Description

Mall yarn, fabrics and clothing products CROSS-REFERENCE TO RELATED APPLICATIONS

[0001] This application claims priority from Japanese Patent Application No. 2023-118500, the contents of which are incorporated herein by reference.

[0002] The present invention relates to a mohair yarn, a fabric comprising the mohair yarn, and a clothing product comprising the fabric.

[0003] Mole yarn is a fiber material containing a core yarn and multiple decorative yarns held by the core yarn. Compared to a yarn consisting only of a core yarn, mole yarn has multiple fluffy, bulky decorative yarns that cover the core yarn, resulting in a thick, fluffy appearance. Due to this distinctive appearance, mole yarn is also called chenille yarn. Mole yarn is generally used as a decorative thread for the collars of fashion clothing, and is often sold in craft stores as embroidery thread or hand-knitting thread.

[0004] Patent Document 1 discloses a mohair yarn using a twisted yarn of a core yarn and a presser yarn. In this mohair yarn, an effect yarn is fused and fixed between the core yarn and the presser yarn, and the effect yarn has a crimp with a curvature radius of 0.5 mm or more and 5.0 mm or less. Patent Document 1 explains that such crimp can improve the bulkiness of the mohair yarn, making the mohair yarn suitable for use as a stuffing.

[0006] On the other hand, mohair yarns generally have the problem that each of the multiple effect yarns easily falls off from the core yarn during washing. In areas where an effect yarn falls off, the core yarn is exposed, damaging the bulky, fluffy appearance resulting from the multiple effect yarns. For this reason, the use of mohair yarns has traditionally been undesirable for applications such as the manufacture of clothing that is washed repeatedly on a daily basis, or for the manufacture of fabrics that serve as materials for such clothing. Furthermore, marine pollution by microplastics has become a problem in recent years. Considering these factors, when using synthetic resin fibers as the effect yarns of mohair yarns, it is desirable that the effect yarns do not easily fall off from the core yarn even when fabrics or clothing containing mohair yarns are washed. Furthermore, while bulkier clothing generally has the advantage of increased heat retention, it is prone to problems such as increased weight and stuffiness. It is desirable to eliminate these problems and produce clothing that is as comfortable to wear as possible.

[0007] Therefore, an object of the present invention is to provide a mohair yarn that is lightweight, has heat-retaining properties and breathability, and that can be easily used to produce a fabric in which the shedding of decorative threads is suppressed, and the fabric and clothing product.

[0008] In order to solve the above-mentioned problems, a molle yarn according to one embodiment is a molle yarn including a core yarn and a plurality of effect yarns held by the core yarn, wherein the core yarn comprises a plurality of first long filaments, each of which has a single fiber fineness of 0.3 dtex or more and 5.0 dtex or less, and each of the effect yarns comprises a plurality of second long filaments, and a fixing part is formed by being held by the core yarn, each of which has a single fiber fineness of 0.3 dtex or more and 8.0 dtex or less, When the longitudinal direction of the molle yarn and the longitudinal direction of each of the effect yarns are oriented horizontally, the linear distance between the core yarn and the tip of each of the second long filaments is defined as a height T1 of each of the second long filaments, and when each of the second long filaments is stretched so as to be linear in a direction perpendicular to the longitudinal direction of the molle yarn, the linear distance between the core yarn and the tip of each of the second long filaments is defined as a height T2 of each of the second long filaments, and the ratio of the height T1 to the height T2 (the height T1 / the height T2) is 0.88 or more.

[0010] The mohair yarn according to the present invention is a fiber material including at least one core yarn and a plurality of effect yarns held by the at least one core yarn. The plurality of effect yarns included in the mohair yarn may be a plurality of relatively short effect yarns (a plurality of fragmented effect yarns) formed by cutting one or more relatively long effect yarns during the manufacturing process of the mohair yarn.

[0011] Although not shown, the mohair yarn according to the present invention may include two or more core yarns. For example, when the mohair yarn according to the present invention includes two core yarns, the two core yarns may be twisted together to form a two-ply yarn in such a way that a portion of each effect yarn is sandwiched between the two core yarns. For example, when the mohair yarn according to the present invention includes three core yarns, the three core yarns may be twisted together to form a triplet yarn in such a way that a portion of each effect yarn is sandwiched between the three core yarns. If necessary, two or more core yarns having the same constituent resin, etc. may be used, or two or more core yarns having different constituent resins, etc. may be used. When two or more core yarns are used, at least one of them may be called a core yarn and at least one of them may be called a pressure yarn. The effect yarn may also be called a feather yarn.

[0012] <Embodiment 1> In the following, in this specification, examples of embodiments will be described with reference to several drawings. The same or similar parts in each drawing are designated by the same or similar reference numerals. In addition, this specification mainly describes a mohair yarn 10a according to embodiment 1 shown in Figure 1, but the present invention is not limited to this one embodiment of the mohair yarn 10a.

[0013] The mall yarn 10a includes one chain knitted core yarn 20 and a plurality of effect yarns 30a held by the one core yarn 20. Each effect yarn 33 included in the plurality of effect yarns 30a is held by the core yarn 20 so as to be sandwiched and fixed by the core yarn 20.

[0014] The core yarn 20 is a multifilament yarn containing a plurality of first long fibers. Each of the first long fibers contained in the core yarn 20 is made of a synthetic resin, and therefore is more stretchy and dries faster than staple fibers such as wool. For the same reasons, the core yarn 20 has superior tensile strength, is less prone to breakage, and is easier to handle than spun yarns spun from staple fibers.

[0015] Each of the first long fibers included in the core yarn 20 may be a thermoplastic polymer produced by condensation polymerization, such as polyamide or polyester, from the viewpoint of being crystalline and having a relatively high melting point, and therefore being resistant to settling even when heated during cleaning, etc. The first long fibers may be, for example, polyamide-based fibers, from the viewpoint of excellent flexibility. Examples of polyamides that can form polyamide-based fibers include nylon 6, nylon 66, para-aramid (e.g., a polycondensate of p-phenylenediamine and terephthalic acid chloride), and meta-aramid (e.g., a polycondensate of m-phenylenediamine and isophthalic acid chloride).

[0016] Each of the first long fibers contained in the core yarn 20 is preferably a polyester-based fiber, from the viewpoints of shrinkage resistance in washing, quick drying, and ease of crimping. The polyester constituting the polyester-based fiber is a polycondensation product of a polycarboxylic acid and a polyol. Examples of polyester include polyethylene terephthalate (hereinafter also referred to as "PET"), polytrimethylene terephthalate, polybutylene terephthalate, polyethylene naphthalate, and polybutylene naphthalate. The first long fiber may be a fiber made of one of the polymers exemplified here as the constituent resin of polyamide-based or polyester-based fibers, or may be a conjugate fiber made of two or more polymers, from the viewpoint of ease of crimping.

[0017] Each of the first long fibers contained in the core yarn 20 is preferably a polyester fiber copolymerized with an ester-forming sulfonic acid metal salt compound represented by the following formula (i) and / or an ester-forming sulfonic acid phosphonium salt compound represented by the following formula (ii), from the viewpoints of converting alkaline sweat to weakly acidic upon contact with the sweat, thereby inhibiting the growth of bacteria, reducing the ammonia odor of sweat, and facilitating removal of stains from the fiber surface during washing:

[0018]

[0020] In the above formula (i), A １represents an aromatic group or an aliphatic group, preferably an aromatic hydrocarbon group having 6 to 15 carbon atoms or an aliphatic hydrocarbon group having 10 or less carbon atoms, and more preferably an aromatic hydrocarbon group having 6 to 12 carbon atoms (for example, a benzene ring). １ represents an ester-forming functional group, and examples thereof include functional groups represented by the following formula (iii).

Examples of the compound include one or more compounds selected from sodium 2,6-dicarbomethoxynaphthalene-4-sulfonate, potassium 2,6-dicarbomethoxynaphthalene-4-sulfonate, lithium 2,6-dicarbomethoxynaphthalene-4-sulfonate, sodium 2,6-dicarbomethoxynaphthalene-1-sulfonate, sodium 2,6-dicarbomethoxynaphthalene-3-sulfonate, sodium 2,6-dicarbomethoxynaphthalene-4,8-disulfonate, sodium 2,6-dicarboxynaphthalene-4,8-disulfonate, sodium 2,5-bis(hydroethoxy)benzenesulfonate, and sodium α-sodium sulfosuccinate.

[0025] Examples of the ester-forming sulfonate phosphonium salt compound represented by the formula (ii) include 3,5-dicarboxybenzenesulfonic acid tetrabutyl phosphonium salt, 3,5-dicarboxybenzenesulfonic acid ethyl tributyl phosphonium salt, 3,5-dicarboxybenzenesulfonic acid benzyl tributyl phosphonium salt, 3,5-dicarboxybenzenesulfonic acid phenyl tributyl phosphonium salt, 3,5-dicarboxybenzenesulfonic acid tetraphenyl phosphonium salt, 3,5-dicarboxybenzenesulfonic acid butyl triphenyl phosphonium salt, 3,5-dicarboxybenzenesulfonic acid benzyl triphenyl phosphonium salt, 3,5-dicarboxybenzenesulfonic acid tetrabutyl phosphonium salt, 3,5-dicarboxybenzenesulfonic acid ethyl tributyl phosphonium salt, 3,5-dicarboxybenzenesulfonic acid benzyl tributyl phosphonium salt, 3,5-dicarboxybenzenesulfonic acid phenyl tributyl phosphonium salt, 3,5-dicarboxybenzenesulfonic acid tetraphenyl phosphonium salt, 3,5-dicarboxybenzenesulfonic acid ethyl triphenyl phosphonium salt , 3,5-dicarboxybenzenesulfonic acid butyltriphenylphosphonium salt, 3,5-dicarboxybenzenesulfonic acid benzyltriphenylphosphonium salt, 3-carboxybenzenesulfonic acid tetrabutylphosphonium salt, 3-carboxybenzenesulfonic acid tetraphenylphosphonium salt, 3-carbomethoxybenzenesulfonic acid tetrabutylphosphonium salt, 3-carbomethoxybenzenesulfonic acid tetraphenylphosphonium salt, 3,5-di(β-hydroxyethoxycarbonyl)benzenesulfonic acid tetrabutylphosphonium salt, 3,5- Examples of the compound include one or more compounds selected from di(β-hydroxyethoxycarbonyl)benzenesulfonic acid tetraphenylphosphonium salt, 3-(β-hydroxyethoxycarbonyl)benzenesulfonic acid tetrabutylphosphonium salt, 3-(β-hydroxyethoxycarbonyl)benzenesulfonic acid tetraphenylphosphonium salt, 4-hydroxyethoxybenzenesulfonic acid tetrabutylphosphonium salt, 2,6-dicarboxynaphthalene-4-sulfonic acid tetrabutylphosphonium salt, and α-tetrabutylphosphonium sulfosuccinic acid.

[0026] From the viewpoint of reducing the environmental burden and contributing to the realization of a sustainable society as advocated by the SDGs, it is preferable that each of the first long fibers contained in the core yarn 20 is a chemically recycled or material recycled polyester fiber.

[0027] The core yarn 20 may be a multifilament yarn containing a plurality of first long fibers made of one type of polymer selected from the several polymers exemplified above as polyamide-based fibers or polyester-based fibers, or may be a multifilament yarn containing a plurality of first long fibers made of two or more types of different constituent polymers.

[0028] From the viewpoint of making the core yarn 20 less prone to settling and easily maintaining the state in which the effect yarn 33 is held, the single fiber fineness of each first long filament contained in the core yarn 20 is 0.3 dtex or more, preferably 0.4 dtex or more, and more preferably 0.5 dtex or more. If the single fiber fineness of the first long filament is less than 0.3 dtex, the first long filament is too thin and easily breaks, making the core yarn more prone to settling and unsuitable for practical use. From the viewpoint of making the effect yarn 33 less prone to falling off from the core yarn 20, the single fiber fineness of each first long filament is 5.0 dtex or less, preferably 3.0 dtex or less, and more preferably 2.0 dtex or less. If the single fiber fineness of the first long filament exceeds 5.0 dtex, the problem of the effect yarn falling off during washing becomes more likely to become apparent. Although the mechanism is unclear, it is presumed that when the single fiber fineness of the first long filament is 5.0 dtex or less, the first long filament contained in the core yarn 20 and the second long filament contained in the effect yarn 33 have thicknesses that make them easy to entangle with each other, and the entanglement makes it difficult for the effect yarn 33 to slip off from the core yarn 20.

[0029] In this specification, the fineness is the average value of 10 measurements of the mass of 100 m of yarn or fiber, multiplied by 100 to calculate the fineness value, and the process is repeated 10 times.

[0030] The total fineness of the core yarn 20 may be 30 dtex or more or 40 dtex or more, preferably 50 dtex or more, and more preferably 60 dtex or more, from the viewpoint of preventing the core yarn 20 from becoming worn out. The total fineness of the core yarn 20 may be, for example, 100 dtex or less, preferably 90 dtex or less, and more preferably 80 dtex or less, from the viewpoint of preventing the effect yarns 33 from falling out of the core yarn 20 and making it easy to produce a lightweight, highly breathable fabric.

[0031] From the viewpoint of holding the effect yarns 30 so as to prevent them from falling off, the core yarn 20 is preferably a multifilament yarn that has been false-twisted and crimped. The crimp percentage of the crimped core yarn 20 may be, for example, 3% or more, preferably 5% or more, and more preferably 10% or more, from the viewpoint of making it easier to hold the effect yarns 30 so as to prevent them from falling off and making it easier to produce a fabric with a soft texture. The crimp percentage of the crimped core yarn 20 may be, for example, 40% or less, preferably 30% or less, and more preferably 20% or less, from the viewpoint of making it easier to produce a fabric with a relatively uniform texture without unevenness by suppressing the resilience of the core yarn 20 from becoming too strong.

[0032] In this specification, the crimp rate is a measured value measured by a method in accordance with "8.12.2 Crimp rate and residual crimp rate" of JIS L 1015-2010.

[0033] When the core yarn 20 is false-twisted and crimped, it is preferably a false-twist crimped yarn. False-twist crimped yarn has torque in the S or Z direction, depending on the direction of twist. Examples of false-twist crimped yarn include so-called one-heater false-twist crimped yarn, in which the false twist is set in the first heater zone, and so-called second-heater false-twist crimped yarn, in which the torque is reduced by further introducing the yarn into the second heater zone and subjecting it to a relaxation heat treatment.

[0034] Each of the effect yarns 33 is a fiber group including a plurality of second long fibers made of synthetic resin. Each of the second long fibers included in the effect yarns 33 may be a polyamide fiber or a polyester fiber from the viewpoint of being resistant to settling even when heated during cleaning, etc. Each of the second long fibers is preferably a polyester fiber from the viewpoint of being resistant to shrinkage when washed, quick to dry, and easy to impart crimp. The effect yarns 33 may be a fiber group including one type of second long fiber having the same constituent polymer, or a fiber group including two or more types of second long fibers having different constituent polymers. Each of the second long fibers may be a fiber including one type of polymer selected from the polymers described above in the description of the first long fiber included in the core yarn 20. However, from the viewpoint of easily giving the effect yarns 33 a bulky appearance, it is preferable that the second long fiber be a conjugate fiber including two or more types of polymers. Since conjugate fibers tend to have crimps, the effect filaments 33 formed from a group of conjugate fibers tend to have a bulky appearance due to the crimps of each conjugate fiber.

[0035] Each of the second long filaments contained in the effect yarns 33 may be a long filament having a typical circular cross-sectional shape, but is preferably a long filament having an irregular cross-sectional shape (a long filament having a non-circular cross-sectional shape). For example, the above-mentioned conjugate fibers or fibers having various irregular cross-sectional shapes, such as cross-shaped, Y-shaped, or W-shaped, can be used as each of the second long filaments. When a long filament having an irregular cross-sectional shape is used as each of the second long filaments in the mohair yarn 10a, when a plurality of such long filaments are bundled together, the irregularities and grooves formed on each long filament make it difficult for the long filaments to pack together, forming relatively large inter-fiber spaces. This is preferable from the viewpoint that the inter-fiber spaces allow a fabric made from the mohair yarn 10a to easily exhibit heat retention, sweat absorption, quick-drying properties, and a dry touch (a smooth and refreshing feel). Furthermore, compared with long fibers with a circular cross section, long fibers with an irregular cross section are preferred from the viewpoint that they are more likely to be caught on and entangled with the first long fibers included in the core yarn 20 due to the irregularities and grooves formed on the long fibers, and therefore the effect yarns 33 are less likely to fall off from the core yarn 20. From the same viewpoint, each of the second long fibers is more preferably a long fiber with one or more irregular cross sections selected from hollow fibers having a hollow portion formed in the fiber cross section, flat fibers having a substantially flat fiber cross section, and false-twisted and crimped fibers having a grooved fiber cross section and a fiber cross section whose shape varies along the fiber axis direction.

[0036] A preferred example of the hollow fiber is a polyester fiber having a central hollow portion in its cross section and a plurality of protrusions radially arranged around the central hollow portion, as shown in Fig. 2A. This hollow fiber (Fig. 2A) is preferable from the viewpoints that, when a plurality of hollow fibers are bundled together, the eight protrusions on each hollow fiber tend to form relatively large interfiber spaces, resulting in excellent heat retention, sweat absorption, and quick-drying properties, and that the eight protrusions and hollow portions make the fiber significantly lighter than a fiber with a circular cross section having the same fiber diameter. A preferred example of the flat fiber is a polyester fiber having a substantially flat cross section, as shown in Fig. 2B, in which three grooves are formed by four convex portions on each side of the fiber. This flat fiber (Fig. 2B) is preferable from the viewpoints that, compared with fibers with circular cross sections, when a plurality of flat fibers are bundled, the convex portions of each flat fiber form relatively large inter-fiber spaces, the absorbed sweat (moisture) is easily diffused by the grooves, and the flat fiber (Fig. 2B) has excellent sweat absorption (water absorption), excellent quick-drying properties, and excellent anti-transparency due to its approximately flat shape, and the fiber is easily bendable and exhibits unique flexibility and drapeability. A preferred example of the false-twisted crimped fiber described above is a false-twisted crimped fiber, as shown in Fig. 2C, in which a polyester fiber having grooves formed on the sides of the fiber is false-twisted and crimped, so that the shape of the fiber cross section where the grooves are formed changes irregularly along the fiber axis. This false twisted and crimped fiber ( FIG. 2C ) has an irregular fiber cross section compared to a fiber with a circular cross section. This means that when a plurality of false twisted and crimped fibers are bundled together, large interfiber spaces are formed, resulting in excellent lightness, sweat absorption, quick drying, and a dry feel. Furthermore, the irregular fiber cross section, due to its irregularities and grooves, makes it easy for the fibers to become entangled with each of the first long fibers and less likely to fall off from the core yarn 20, making it preferable from the viewpoint of excellent washing durability.

[0037] From the viewpoints of inhibiting the growth of bacteria, reducing the ammonia odor of sweat, and facilitating removal of stains from the fiber surface during washing, each of the second long fibers contained in the effect yarns 33 is preferably a polyester fiber copolymerized with an ester-forming metal sulfonate compound represented by the above formula (i) and / or an ester-forming phosphonium sulfonate compound represented by the above formula (ii). From the viewpoints of reducing the environmental load and contributing to the realization of a sustainable society as advocated by the SDGs, each of the second long fibers contained in the effect yarns 33 is preferably a chemically recycled or material recycled polyester fiber.

[0038] From the viewpoint of improving heat retention by forming the effect yarn 33 with a fluffy and bulky appearance to some extent, the single fiber fineness of each second long filament contained in the effect yarn 33 is 0.3 dtex or more, preferably 0.4 dtex or more, and more preferably 0.5 dtex or more. If the single fiber fineness of the second long filament is less than 0.3 dtex, each second long filament will be too thin and prone to settling, and multiple second long filaments will tend to lie along the longitudinal axis of the chain-stitched core yarn 20, making it difficult to fluff the effect yarn. From the viewpoint of preventing the effect yarn 33 from falling off the core yarn 20, the single fiber fineness of each second long filament contained in the effect yarn 33 is 8.0 dtex or less, and may be 6.5 dtex or less or 5.0 dtex or less, preferably 3.0 dtex or less, and more preferably 2.0 dtex or less. If the single fiber fineness of the second long filament exceeds 8.0 dtex, the effect yarns will be more likely to fall off during washing. It is thought that if each second long filament contained in the effect yarns 33 has a single fiber fineness of 8.0 dtex or less, it will have a thickness that makes it easy to entangle with each first long filament contained in the core yarn 20, and the effect yarns 33 will be less likely to fall off from the core yarn 20 due to the entanglement.

[0039] The plurality of second long filaments contained in each effect yarn 33 may be in a state in which the spaces between the respective second long filaments are somewhat open, as exemplified in Fig. 1 . The single filament fineness of each effect yarn 33, which can be calculated as the sum of the single filament finenesses of the respective second long filaments, may be 30 dtex or more or 50 dtex or more, preferably 60 dtex or more, and more preferably 70 dtex or more, from the viewpoint of giving the effect yarn 33 a fluffy and bulky appearance to some extent. The single filament fineness of each effect yarn 33 may be, for example, 200 dtex or less or 150 dtex or less, preferably 100 dtex or less or 90 dtex or less, and more preferably 80 dtex or less, from the viewpoint of preventing the effect yarn 33 from falling out of the core yarn 20 and facilitating the production of a lightweight and highly breathable fabric.

[0040] From the viewpoint of forming the effect yarn 33 having a fluffy, bulky appearance and improving heat retention, each second long filament contained in the effect yarn 33 may be a fiber having crimp. From the same viewpoint, the radius of curvature indicating the magnitude of crimp in the second long filament may be, for example, 2.0 mm or less, 1.0 mm or less, or 0.50 mm or less, preferably 0.40 mm or less, more preferably 0.35 mm or less, and even more preferably 0.30 mm or less. On the other hand, if each second long filament has excessive crimp, the second long filaments may be entangled with each other more than necessary, which may easily cause clumps or unevenness in a fabric made from the mohair yarn, and may result in some loss of heat retention. From the viewpoint of imparting crimp so as to facilitate heat retention, the radius of curvature indicating the magnitude of crimp in each second long filament contained in the effect yarn 33 may be, for example, 0.10 mm or more, preferably 0.15 mm or more. From the viewpoint of easily satisfying the curvature radius condition given here, the false twisted crimped yarn described above in the explanation of the core yarn 20 may be used as the effect yarn 33. When used as the effect yarn 33 in this way, the plurality of crimped long filaments contained in the false twisted crimped yarn can be treated as a plurality of second long filaments.

[0041] In this specification, the radius of curvature is a measured value of the radius of the curved shape formed by sampled long filaments 34, as shown in Fig. 3, using an image observed two-dimensionally with a microscope. The radius of curvature is measured by cutting or extracting one second long filament from ten locations randomly selected at regular intervals in the direction X along the longitudinal direction of the mohair yarn 10a, and observing each of the sampled long filaments 34 with a microscope at a magnification that allows the crimp form to be confirmed. Using the observed image, the radius of the curved shape formed by the crimped long filaments is measured ten or more times, and the average of the measured values ​​is defined as the radius of curvature of the long filaments.

[0042] 1, 4, and 7A, in the mohair yarn 10a, a part of each effect yarn 33 (plurality of second long filaments) is sandwiched and fixed within a loop 25 formed by chain stitching in one core yarn 20, thereby forming a fixed part 37 in each effect yarn 33. In other words, the fixed part 37 is formed by a part of each effect yarn 33 (plurality of second long filaments) being wound around and compressed by the core yarn 20, and being fixed between the core yarns 20. Moreover, in order to explain the positional relationship of each effect yarn 33 in the mohair yarn 10a, Fig. 7B shows a plurality of effect yarns 30a in a state in which the core yarn 20 is removed from the mohair yarn 10a shown in Fig. 7A. The remaining portions of each effect yarn 33 (plurality of second long filaments) that do not form the fixed portions 37 are in a state in which each second long filament extends from the fixed portion 37 in the circumferential direction of the core yarn 20 as if blooming to some extent, forming a wing portion, or are in a state in which the second long filaments are pulled between two fixed portions 37 and are bundled together with the core yarn 20, forming a composite portion 40 ( FIG. 7A ).

[0043] From the viewpoint of facilitating the production of a fabric with excellent heat retention due to the appearance of each effect yarn 33 being somewhat bulky, the height T1 of each second long filament may be, for example, 1.5 mm or more, 3.0 mm or more, or 5.0 mm or more, preferably 6.0 mm or more, and more preferably 7.0 mm or more. From the viewpoint of facilitating the production of a lightweight and highly breathable fabric, the height T1 of each second long filament may be, for example, 15 mm or less, 12 mm or less, or 10 mm or less, preferably 9.0 mm or less, and more preferably 8.0 mm or less. The height T1 of each second long filament listed here is the shortest linear distance between the core yarn 20 and the tip (35a or 35b) of each second long filament when the longitudinal direction of the molle yarn 10a and the longitudinal direction of each effect yarn 33 (each second long filament) are oriented horizontally (when they are on the XY plane in FIG. 4 ), as shown in FIG. In this case, the longitudinal direction of the mohair yarn 10a is oriented in the direction X, which is along any one direction in the horizontal XY plane. In other words, the height T1 can be said to be the height from the core yarn 20 to the tip (35a or 35b) of each second long filament when each second long filament is lying on the horizontal XY plane without being subjected to an external force (e.g., a traction force).

[0044] From the viewpoint of facilitating the production of a lightweight and highly breathable fabric, the height T2 of each second long filament may be, for example, 15 mm or less, 12 mm or less, or 10 mm or less, preferably 9.5 mm or less, and more preferably 8.5 mm or less. The height T2 of each second long filament listed here is the shortest linear distance between the core yarn 20 and the tip of each second long filament (35a or 35b) when the longitudinal direction of the molle yarn 10a and the longitudinal direction of each effect yarn 33 (each second long filament) are oriented horizontally (on the XY plane in FIG. 4 ), and each second long filament is stretched linearly in direction Y perpendicular to direction X along the longitudinal direction of the molle yarn 10a. In other words, the height T2 can be said to be the height from the core yarn 20 to the tip (35a or 35b) of each second long filament when the second long filaments are stretched by applying an external force (e.g., a traction force) to the second long filaments so that the second long filaments are linearly stretched in a direction Y perpendicular to the direction X along the longitudinal direction of the mohair yarn on a horizontal XY plane.

[0045] From the viewpoint of facilitating the production of a fabric with excellent breathability, the ratio of the above-mentioned two heights (height T1 / height T2) of each second long filament is 0.880 or more, for example, may be 0.89 or more, preferably 0.90 or more, and more preferably 0.91 or more. When the ratio of the heights of each second long filament (height T1 / height T2) is 0.88 or more, the mohair yarn 10a has an appearance under a microscope in which a plurality of second long filaments contained in the effect yarns 33 stand up from the core yarn 20. This appearance, combined with the fact that each second long filament is thin, allows air to easily pass through the mohair yarn 10a in the orthogonal direction Y. If the height ratio (height T1 / height T2) is less than 0.88, the lower this ratio becomes, the more each second long filament will lie in direction X along the longitudinal direction of the mohair yarn, and the more the flow of air passing through in direction Y perpendicular to the direction X will be obstructed by the effect yarns (plurality of second long filaments), resulting in a loss of breathability of the fabric containing the mohair yarn.

[0046] The height T1 of each second long filament in this specification is a value obtained by the following method. A piece of black paper is placed on a flat table surface extending horizontally, and a molle yarn is placed on the black paper. A sample is prepared by attaching the core yarn to the black paper so that the longitudinal direction of the molle yarn is generally linear. Care is taken during attachment so that the second long filament does not get attached to the black paper. If any effect yarn is entangled with the core yarn, the effect yarn is untangled from the core yarn before attaching the core yarn to the black paper to prepare a sample. This sample is photographed at 10 locations using a microscope at 50x magnification, and the linear distance between the core yarn 20 and the tip (35a or 35b) of the second long filament is measured for each second long filament using the obtained images at 10 locations, as shown in FIG. 4 . This linear distance is measured for 50 second long filaments, and the average value is defined as the height T1 of each second long filament.

[0047] The height T2 of each second long filament in this specification is a value obtained by the following method. In a sample after calculating the value of the height T1 described above, for each of the same 50 second long filaments for which the linear distance described above for calculating the height T1 was measured, the tip (35a or 35b) of the second long filament is pinched and pulled in a direction Y perpendicular to the direction X along the longitudinal direction of the molle yarn to straighten it, and the tip (35a or 35b) of the second long filament is then attached to black paper. The sample is in a state in which the second long filament is held on the black paper in a linearly stretched state. Using a microscope at 50x magnification, the linear distance between the core yarn 20 and the tip (35a or 35b) of the second long filament is measured for each of the 50 attached second long filaments. The linear distances are measured for the 50 second long filaments, and the average value is defined as the height T2 of each second long filament.

[0048] The present inventors have found that when a certain number of effect yarns 33 are held by a certain length of core yarn 20, the effect yarns 33 are even less likely to fall off from the core yarn 20. It is presumed that when the fixing portions 37 of the effect yarns 33 sandwiched between the core yarns 20 reach a certain thickness or more, the thickness of the fixing portions 37 compresses the core yarn 20, making it easier for the fixing portions 37 to be stably held between the core yarns 20. From this perspective, in the direction X along the longitudinal direction of the molle yarn 10a, the distance between the fixing portions 37 at which the effect yarns 33 are held by the core yarn 20 may be, for example, 6.0 mm or less or 4.0 mm or less, preferably 2.0 mm or less or 1.5 mm or less, and more preferably 1.2 mm or less. In other words, in the direction X along the longitudinal direction of the mohair yarn 10a, the number of fixing portions 37 at which the effect yarns 33 are gripped may be, for example, 4.2 parts / inch or more or 6.4 parts / inch or more, preferably 12.7 parts / inch or more or 16.9 parts / inch or more, and further preferably 21.2 parts / inch or more.

[0049] Furthermore, if too many effect yarns 33 are held for a given length of core yarn 20, the core yarn 20 is excessively compressed by the excessive number of fixing parts 37, and some of the effect yarns 33 are likely to be pushed out from between the core yarns 20. In other words, it is presumed that there is an upper limit to the amount of effect yarns 33 that the core yarn 20 can stably hold, and if the core yarn 20 holds more effect yarns 33 than this upper limit, some of the effect yarns 33 are likely to fall off from the core yarn 20 depending on the amount in excess. Furthermore, to achieve a soft texture for a fabric made using the mohair yarn 10a, it is desirable that the core yarn 20 is not too compressed and is somewhat flexible. From these viewpoints, the spacing between the fixing parts 37 in the direction X along the longitudinal direction of the mohair yarn 10a may be, for example, 0.5 mm or more, preferably 0.7 mm or more, and more preferably 0.9 mm or more. In other words, the number of fixed portions 37 in the direction X along the longitudinal direction of the mohair yarn 10a may be, for example, 50 parts / inch or less, preferably 36 parts / inch or less, and more preferably 28 parts / inch or less.

[0050] The interval between the above-mentioned fixing parts 37 is an average value obtained by measuring the intervals between adjacent fixing parts 37 using the images obtained by making a sample in which the mohair yarn 10a is generally straight so that the direction X along the longitudinal direction of the mohair yarn 10a is horizontal, and by untangling the effect yarns 33 entangled with the core yarn 20 so that each effect yarn 33 faces the direction Y perpendicular to the direction X, and then photographing this sample at 10 points using a microscope at a magnification of 50 times.

[0051] 1 , 4 , 7A and 7B , in the molle yarn 10a, each effect yarn 33 is held by the core yarn 20 so that two fixing portions 37 are formed in each effect yarn 33. That is, a plurality of constricted loops 25 are formed in the core yarn 20, and each effect yarn 33 (a plurality of second long filaments) passes through two of the plurality of loops formed in the core yarn midway in the longitudinal direction of the fiber, and is fixed in each of the constricted loops 25. As described above, in the molle yarn 10a, each effect yarn 33 has two fixing portions, and therefore each effect yarn 33 is more strongly held by the core yarn 20 and less likely to fall off from the core yarn 20 than an effect yarn having only one fixing portion. Furthermore, as described above, the portion between the two fixing portions 37 in each effect yarn 33 is bundled with the core yarn 20 to form the composite portion 40. In this composite portion 40, the plurality of first long fibers contained in the core yarn 20 and the plurality of second long fibers contained in each of the effect yarns 33 tend to be somewhat entangled with each other, which is thought to be why each of the effect yarns 33 in the mohair yarn 10a is configured to be less likely to fall off from the core yarn 20.

[0052] The total fineness of the mohair yarn 10a may be, for example, 550 dtex or more, preferably 600 dtex or more, and more preferably 650 dtex or more, from the viewpoint of easily producing a fabric with a bulky appearance and heat retention using the mohair yarn 10a. The total fineness of the mohair yarn 10a may be, for example, 1,300 dtex or less or 1,000 dtex or less, preferably 900 dtex or less, and more preferably 800 dtex or less, from the viewpoint of easily producing a fabric with a relatively light weight and high breathability using the mohair yarn 10a.

[0053] Each effect yarn 33 may be fusion-fixed to the core yarn 20 at one or more portions selected from the fixing portion 37 and the composite portion 40. In this case, the plurality of first long fibers contained in the core yarn 20 may contain a low-melting-point polyester fiber in a range of 10% by mass or less of the core yarn 20. Furthermore, in this case, the plurality of second long fibers contained in the effect yarn 33 may contain a low-melting-point polyester fiber in a range of 10% by mass or less of the effect yarn 33. The low melting point here may be, for example, higher than 130°C and lower than 150°C. Examples of such low-melting-point polyester fibers include block copolymers containing polyester in the hard segment and polyether or polyester in the soft segment.

[0054] However, when a fabric is produced using the mohair yarn 10a in which the effect yarns 33 and the core yarn 20 are fused and fixed, the texture of the resulting fabric becomes somewhat hard. From the viewpoint of easily producing a fabric with a soft texture, it is preferable that the mohair yarn 10a is such that each effect yarn 33 is not substantially fused and fixed to the core yarn 20. To achieve this, for example, it is preferable that the plurality of first long filaments contained in the core yarn 20 and the plurality of second long filaments contained in the effect yarns 33 are made of polyester-based fibers having a melting point of 150°C or higher.

[0055] The method for producing the mohair yarn 10a is not particularly limited, and a person skilled in the art can produce it by a conventional method (see, for example, Patent Document 2) based on the description in this specification. As an example, the mohair yarn 10a can be produced by the method described below. First, n core yarns that have not yet been chain knitted and (n-1) long effect yarns that have not yet been cut are prepared. n is a natural number of 3 or more. The n core yarns are arranged in parallel and chain knitted, and each long effect yarn is alternately swung between the core yarn adjacent to the right and the core yarn adjacent to the left, and knitted over the core yarn, thereby producing the mohair yarn 10a.

[0056] 5 and 6, an example of the above-mentioned manufacturing method will be described in which n = 3. As shown in Fig. 5, a first wale 50a, a second wale 50b, and a third wale 50c are arranged in parallel from left to right, and the mohair yarn 10a is manufactured through steps S1 to S5 described below.

[0057] In step S1, one core yarn (20a, 20b, or 20c) is arranged in each wale (50a, 50b, and 50c). In the first wale 50a, which is the leftmost, the core yarn 20a that has not yet been chain knitted is overlapped with the first long effect yarn 31 that has not yet been cut, and a loop 25a1 is knitted in which the core yarn 20a and the first long effect yarn 31 overlap. In the second wale 50b, which is adjacent to the right of the first wale 50a, a loop 25b1 is knitted in which the core yarn 20b and the second long effect yarn 32 that has not yet been cut overlap. Meanwhile, in the third wale 50c, which is adjacent to the right of the second wale 50b (the rightmost), a loop 25c1 made only of the core yarn 20c is knitted.

[0058] In the next step S2, in the first wale 50a on the far left, only the first long effect yarn 31 is stretched from the loop (25a1 or 25a3 described later) in which the core yarn 20a and the first long effect yarn 31 formed in the "previous step" overlap, to the second wale 50b on the adjacent right, and only the core yarn 20a is passed through this loop (25a1 or 25a3 described later), to knit a new loop 25a2 made of only the core yarn 20a. In the second wale 50b, only the second long effect yarn 32 is stretched from the loop (25b1 or 25b3 described later) formed in the "previous process" where the core yarn 20b and the second long effect yarn 32 overlap, to the adjacent third wale 50c on the right, and the core yarn 20b is overlapped with the first long effect yarn 31 stretched from the adjacent first wale 50a on the left, and passed through the loop (25b1 or 25b3 described later) formed in the "previous process", to knit a new loop 25b2 where the core yarn 20b and the first long effect yarn 31 overlap. In the third wale 50c, the core yarn 20c is stretched from the loop (25c1 or 25c3 described later) made only of the core yarn 20c formed in the "previous step", and overlapped with the second long effect yarn 32 stretched from the second wale 50b on the left, and passed through the loop (25c1 or 25c3 described later) formed in the "previous step", to knit a new loop 25c2 in which the core yarn 20c and the second long effect yarn 32 overlap. Note that in this step S2, the "previous step" refers to the above-mentioned step S1 when step S2 is performed for the first time.

[0059] In the next step S3, in the third wale 50c on the far right side, only the second long effect yarn 32 is stretched from the loop 25c2 in which the core yarn 20c and the second long effect yarn 32 formed in the immediately preceding step S2 overlap, to the adjacent second wale 50b on the left, and only the core yarn 20c is passed through this loop 25c2 to knit a new loop 25c3 made of only the core yarn 20c. In the second wale 50b, only the first long effect yarn 31 is stretched from the loop 25b2 in which the core yarn 20b and the first long effect yarn 31 formed in the immediately preceding step S2 overlap to the adjacent first wale 50a on the left, and the core yarn 20b is overlapped with the second long effect yarn 32 stretched from the adjacent third wale 50c on the right, and passed through the loop 25b2 formed in the immediately preceding step S2, to knit a new loop 25b3 in which the core yarn 20b and the second long effect yarn 32 overlap. In the first wale 50a on the far left side, the core yarn 20a is stretched from the loop 25a2 formed in the immediately preceding step S2 using only the core yarn 20a, and is overlapped with the first long effect yarn 31 stretched from the second wale 50b on the right side, and passed through the loop 25a2 formed in the immediately preceding step S2, to knit a new loop 25a3 in which the core yarn 20a and the first long effect yarn 31 are overlapped.

[0060] Although not shown, in the next step S4, the above-mentioned steps S2 and S3 are alternately repeated multiple times. As a result, while chain knitting one core yarn (20a, 20b, or 20c) in each wale (50a, 50b, and 50c), the first long effect yarn 31 is alternately entangled with and bridges the left adjacent core yarn 20a and the right adjacent core yarn 20b, and similarly, the second long effect yarn 32 is alternately bridges the left adjacent core yarn 20b and the right adjacent core yarn 20c. Note that when step S2 is performed for the second or subsequent times in step S4, the "previous step" in step S2 refers to the immediately preceding step S3.

[0061] After the core yarns (20a, 20b, and 20c) and the first and second long effect yarns 31 and 32 are knitted through the above-described steps S1 to S4, step S5 shown in Fig. 6 is performed. In step S5, the portion of the first long effect yarn 31 bridging the core yarns 20a and 20b is cut at an intermediate position 55a between the first wale 50a and the second wale 50b. By cutting, one first long effect yarn 31 becomes a plurality of relatively short effect yarns 30a (a plurality of fragments of the effect yarn). Similarly, at an intermediate position 55b between the second wale 50b and the third wale 50c, the portion of the second long effect yarn 32 bridging the core yarns 20b and 20c is cut, and a plurality of relatively short effect yarns 30a (a plurality of fragments of the effect yarn) is formed from one second long effect yarn 32. When the core yarn 20b is pulled at both ends, the loops (25b1, 25b2 and 25b3) are squeezed (contracted), and a part of each effect yarn 33 is sandwiched and fixed in each of the squeezed loops 25, thereby forming the mohair yarn 10a.

[0062] Regarding the above-mentioned step S5, Fig. 6 shows an example in which the first long effect yarn 31 and the second long effect yarn 32 are cut, and then the loops (25b1, 25b2, and 25b3) are squeezed to form the mohair yarn 10a. Alternatively, from the viewpoint of further facilitating production of the mohair yarn 10a, it is preferable to form the mohair yarn 10a by squeezing the loops (25b1, 25b2, and 25b3) in the above-mentioned step S4 or step S5 to hold the first long effect yarn 31 and the second long effect yarn 32 with the core yarn 20b, and then cutting the first long effect yarn 31 and the second long effect yarn 32. Furthermore, Figs. 5 and 6 show a method for producing the mohair yarn 10a when n = 3, but a larger number of n is preferable because it allows for the simultaneous production of a larger number of mohair yarns 10a. When n is 4 or more, one mohair yarn 10a can be produced per wale, except for the first wale (the leftmost) and the nth wale (the rightmost). That is, (n-2) mohair yarns 10a can be produced simultaneously. The length of the interval between the intermediate positions 55a and 55b shown in Fig. 6 (i.e., the length of the cut width L between the cut portions of the first long effect yarn 31 and the second long effect yarn 32) tends to be relatively close to twice the height T1 of each second long filament. The lower part of Fig. 6 shows a micrograph of a prototype in which six fixing portions 37 are formed per 0.25 inch in the direction X along the longitudinal direction of the mohair yarn 10a (24 portions / inch). In other words, the interval D between the fixing portions 37 in this case is 1 / 24 inch.

[0063] 5 and 6 , in the mohair yarn 10a formed, for example, in the second wale 50b, a composite portion 40 in which each effect yarn 33 is bundled with the core yarn 20 is continuous in the direction X along the longitudinal direction of the mohair yarn 10a, as shown in Fig. 7A . Note that in Fig. 7A , each effect yarn 33 with its tip (35a and 35b) facing upward (one side) on the paper with respect to the core yarn 20 originates from the first long effect yarn 31. In Fig. 7A , the effect yarn 33 with its tip (35a and 35b) facing downward (the other side) on the paper with respect to the core yarn 20 originates from the second long effect yarn 32. 7B , in the mohair yarn 10a, in the direction X along the longitudinal direction of the mohair yarn 10a, the effect yarns 33 originating from the first long effect yarn 31 and facing upward (one side) on the paper surface and the effect yarns 33 originating from the second long effect yarn 32 and facing downward (the other side) on the paper surface are alternately connected. Therefore, for example, when the mohair yarn 10a is produced using yarns with somewhat different physical properties, the first long effect yarn 31 and the second long effect yarn 32, it is also possible to produce a mohair yarn 10a in which the properties such as softness and texture are significantly different between the upper side (one side) and the lower side (the other side) on the paper surface.

[0064] Although not shown, a fabric according to one embodiment is a fabric containing mohair yarn 10a. Examples include woven or knitted fabrics containing mohair yarn 10a. The fabric may be, for example, a woven fabric formed by interweaving mohair yarn 10a with polyester-based fibers, or a knitted fabric formed by interweaving mohair yarn 10a with polyester-based fibers. To incorporate a certain amount of mohair yarn 10a into the fabric and facilitate the warmth, lightness, and breathability provided by the mohair yarn 10a, the content of the mohair yarn 10a in the fabric may be, for example, greater than 50% by mass, 60% by mass or more, 70% by mass or more, 80% by mass or more, or 90% by mass or more, preferably 95% by mass or more or 98% by mass or more, and even more preferably 99% by mass or more or 100%. In other words, it is even more preferable that the fabric be a woven or knitted fabric essentially consisting of mohair yarn 10a. From the viewpoint of being easier to manufacture than woven fabrics, it is even more preferable that the fabric is a knitted fabric made of mohair yarn 10a.

[0065] In order to easily exert the heat retention properties of the mohair yarn 10a, a certain amount of the mohair yarn 10a is used, and therefore the basis weight of the fabric containing the mohair yarn 10a is, for example, 200 g / m ２ or more, preferably 250 g / m ２ From the viewpoint of making the fabric relatively light and highly breathable, the fabric containing the mohair yarn 10a has a basis weight of, for example, 350 g / m ２ Preferably 300 g / m or less ２ In this specification, the basis weight is a value measured by a measurement method in accordance with 8.3 of JIS L 1096-2010.

[0066] From the viewpoint of ease of use of the fabric in applications for producing textile products (e.g., clothing products) that can be washed repeatedly on a daily basis, the fabric containing the mohair yarn 10a may have a fiber shedding rate of, for example, 0.80% or less or 0.50% or less, preferably 0.30% or less, and more preferably 0.20% or less.

[0067] The fiber shedding rate value in this specification is a value obtained by the following method. (Method for measuring fiber shedding rate) Step 1: Three 300 mm x 300 mm test pieces containing synthetic fibers are obtained from a textile product such as a fabric. At this time, 300 mm x 300 mm pieces are cut from the fabric using a flat nichrome heater soldering iron (Ishizaki Electric Mfg. Co., Ltd., model number: SB-100). Step 2: The mass of the obtained test pieces is measured to the nearest 0.1 μg using an electronic balance. After the mass measurement, the test pieces are washed one by one in a drum-type washing machine without using detergent, in accordance with the JIS L 1930 C4M method. The washed test pieces are dried by tumble drying in the same drum-type washing machine. Step 3: The mass of the dried test pieces is measured to the nearest 0.1 μg using an electronic balance. The measured mass of the test piece before washing is L0, and the measured mass of the test piece after washing and drying is L1. The fiber (microplastic) shedding rate (%) from the test piece is calculated using the following formula: Shedding rate (%) = ((L0 - L1) / L0) x 100

[0068] From the viewpoint of easily producing textile products (e.g., clothing products) that are quick-drying and not prone to sweating, it is preferable that the time required for the diffusible residual moisture content of a fabric containing the mohair yarn 10a to reach 10% or less is 80 minutes or less. The shorter this time, the faster the fabric dries, which is preferable. In this specification, the diffusible residual moisture content is a value calculated by dropping about 0.6 g of water onto a sample (fabric) in an atmosphere of 20°C x 65% RH, measuring the mass at each time, and then using the following formula: Residual moisture content (%) = Moisture content (g) at each time / Moisture content (g) immediately after dropping (back surface) x 100

[0069] From the viewpoint of easily producing textile products (for example, clothing products) that are highly breathable and do not get stuffy, the air permeability of the fabric containing the mohair yarn 10a is preferably 100 cc / (cm ２ · seconds) or more, more preferably 150 cc / (cm ２ In this specification, the air permeability is a measured value measured in accordance with JIS L 1096-2010, 8.26.1 A method (Frazier method).

[0070] From the viewpoint of facilitating the production of textile products (e.g., clothing products) with excellent heat retention, the heat retention rate of the fabric containing the mohair yarn 10a is preferably 60% or more, and more preferably 65% ​​or more. The heat retention rate value in this specification is a value obtained by a measurement method in accordance with JIS L 1096, 8.27.

[0071] Although not shown, a clothing product according to one embodiment is a product comprising a fabric containing molle yarn 10a. Examples of such products include tops, trousers, skirts, outerwear, underwear, sleepwear, hats, gloves, and socks. From the perspective of utilizing the characteristic of molle yarn 10a, namely, that the effect yarn 33 does not easily slip out of the core yarn 20, clothing products comprising a fabric containing molle yarn 10a are preferably general clothing items that are washed repeatedly on a daily basis. Furthermore, from the perspective of utilizing the warmth, lightness, and breathability of molle yarn 10a, clothing products comprising a fabric containing molle yarn 10a are more preferably clothing products that replace conventional fleece clothing. When the clothing product is a clothing product that replaces fleece clothing, the weight of the clothing product is preferably 200 g or more and 450 g or less.

[0072] <Other Embodiments 2 to 8> Hereinafter, mohair yarns (10b to 10g) according to other embodiments will be described with reference to Figures 8A to 13B. These mohair yarns (10b to 10g) each have substantially the same configuration and effects as the mohair yarn 10a (Figure 7A) described above. Explanation of the features common to the mohair yarn 10a will be largely omitted, and differences will be mainly described.

[0073] The mohair yarn 10b according to embodiment 2 shown in Fig. 8A includes one chain-knitted core yarn 20 and multiple effect yarns 30b held by the core yarn 20. Each effect yarn 33 included in the multiple effect yarns 30b has two fixing portions 37 sandwiched within a constricted loop 25 formed in the core yarn 20. The mohair yarn 10b can be produced, for example, in the third wale (nth wale) in the production method (when n = 3) described with reference to Figs. 5 and 6. That is, each effect yarn 33 in the mohair yarn 10b can originate from the second long effect yarn 32, and both the first tip 35a and the second tip 35b face upward (one side) in the plane of Fig. 8A. On the other hand, the mohair yarn 10b does not include an effect yarn whose tip faces downward (the other side) in the plane of Fig. 8A. 8B shows a plurality of effect yarns 30b in a state in which the core yarn 20 is removed from the mohair yarn 10b shown in FIG. 8A in order to explain the positional relationship of each effect yarn 33 in the mohair yarn 10b (note that the relationships between FIGS. 9A and 9B , 10A and 10B , 11A and 11B , 12A and 12B , and 13A and 13B , which will be described later, are similar to the relationships between FIGS. 8A and 8B ). As is clear from FIGS. 8A and 8B , in the direction X along the longitudinal direction of the mohair yarn 10b, composite portions 40 in which the core yarn 20 and each effect yarn 33 are bundled together and portions consisting only of the core yarn 20 are alternately and repeatedly connected. The mohair yarn 10b has a bulky appearance on the upper side (one side) of the paper due to the effect yarns 33, but is lighter than the above-mentioned mohair yarn 10a ( FIG. 7A ) because there are no effect yarns on the lower side (the other side) of the paper.

[0074] The mall yarn 10c according to embodiment 3 shown in Fig. 9A includes one chain-knitted core yarn 20 and multiple effect yarns 30c held by the core yarn 20. Each effect yarn 33 included in the multiple effect yarns 30c has two fixed portions 37 sandwiched within a drawn loop 25 formed in the core yarn 20. Compared to the above-mentioned mall yarn 10b (Figs. 8A and 8B), the mall yarn 10c (Figs. 9A and 9B) has a similar configuration, but differs in that the first tip 35a faces the upper side (one side) of the paper and the second tip 35b faces the lower side (the other side) of the paper. The mall yarn 10c has a bulky appearance due to the effect yarns 33 on both the upper side (one side) and the lower side (the other side) of the paper, and is lightweight compared to the above-mentioned mall yarn 10a (Figs. 7A and 7B) due to the smaller amount of effect yarns 33.

[0075] The mohair yarn 10d according to embodiment 4 shown in Fig. 10A includes one chain-knitted core yarn 20 and multiple effect yarns 30d held by the core yarn 20. Each effect yarn 33 included in the multiple effect yarns 30d has two fixing portions 37 sandwiched within a drawn loop 25 formed in the core yarn 20. As shown in Fig. 10B , in each effect yarn 33 in the mohair yarn 10d, a first tip 35a faces the upper side (one side) of the paper, and a second tip 35b faces the lower side (the other end) of the paper. Compared to the mohair yarn 10a described above (Figs. 7A and 7B), the mohair yarn 10d is likely to have substantially uniform properties such as softness and texture between the upper side (one side) and the lower side (the other side) of the paper, even if the physical properties of the first long effect yarn and the second effect yarn used in the manufacturing process are different.

[0076] The mohair yarn 10e according to embodiment 5 shown in Fig. 11A includes one chain-knitted core yarn 20 and multiple effect yarns 30e held by the core yarn 20. Each effect yarn 33 included in the multiple effect yarns 30e has three fixing portions 37 formed by passing through three of the multiple loops formed and drawn in the core yarn (Fig. 11B), and both the first tip 35a and the second tip 35b face upward (to one side) on the paper. In the direction X along the longitudinal direction of the mohair yarn 10e, composite portions 40 in which each effect yarn 33 is bundled with the core yarn 20 and portions consisting only of the core yarn 20 are alternately and repeatedly connected. In the mohair yarn 10e, each effect yarn 33 has three fixing portions 37, which is preferable from the viewpoint that the effect yarn 33 is less likely to fall off the core yarn 20 compared to the mohair yarn 10b (Figs. 8A and 8B) in which each effect yarn 33 has two fixing portions.

[0077] The mohair yarn 10f according to embodiment 6 shown in Fig. 12A includes one chain-knitted core yarn 20 and multiple effect yarns 30f held by the core yarn 20. Each effect yarn 33 included in the multiple effect yarns 30f has three fixing portions 37 formed therein (Fig. 12B). Each effect yarn 33 in the mohair yarn 10f has a first tip 35a facing upward (one side) on the paper surface and a second tip 35b facing downward (the other side) on the paper surface; apart from this, the mohair yarn 10f is configured in the same manner as the above-mentioned mohair yarn 10e (Fig. 11A).

[0078] The mohair yarn 10g according to embodiment 7 shown in Fig. 13A includes one chain-knitted core yarn 20 and multiple effect yarns 30f held by the core yarn 20. Each effect yarn 33 included in the multiple effect yarns 30f has three fixing portions 37 formed therein (Fig. 13B). In the direction X along the longitudinal direction of the mohair yarn 10g, composite portions 40 in which each effect yarn 33 is bundled together with the core yarn 20 are repeatedly connected, and apart from this point, the mohair yarn 10g is configured in the same manner as the above-mentioned mohair yarn 10e (Fig. 11A).

[0079] In the mohair yarn according to the present invention, from the viewpoint of preventing the effect yarns from falling off the core yarn, it is desirable that each effect yarn has preferably two or more, and more preferably three or more, fixing parts formed thereon. From the viewpoint of avoiding complication of the manufacturing process, the mohair yarn according to the present invention may have five or less, or four or less fixing parts formed thereon.

[0081] According to the molle yarn described in (1) above, the multiple effect yarns tend to give the yarn a bulky appearance and heat retention. Furthermore, since each second long fibrous substance has the above-described monofilament fineness and the above-described ratio (the height T1 / the height T2) is 0.88 or more, when the molle yarn is observed under a microscope, the appearance of each relatively thin second long fibrous substance standing up from the core yarn tends to make the multiple effect yarns lightweight and breathable. Furthermore, since each first long fibrous substance contained in the core yarn has the above-described monofilament fineness, each effect yarn is less likely to fall off from the core yarn.

[0082] The present invention is not limited to the above-described embodiments, and various improvements, modifications, or variations can be made based on the knowledge of those skilled in the art without departing from the spirit of the present invention. The present invention may be embodied in a form in which any specific feature is replaced with another technology within the scope of producing the same action or effect.

[0083] Several examples will be described below, but the present invention is not limited to the following examples.

[0084] Core yarn: False-twisted crimped yarn A1 Polyethylene terephthalate (matting agent content 0.3% by mass, semi-dull (SD)) was melt-spun at 280°C using a conventional spinning apparatus, taken up at a speed of 2,800 m / min, and wound up without stretching to obtain a semi-stretched multifilament yarn. This multifilament yarn contained 36 PET long fibers, each of which had a circular cross-sectional shape. This multifilament yarn was simultaneously stretched and false-twisted crimped under conditions of a draw ratio of 1.6, a false-twist number of 2,500 T / m (S direction), a heater temperature of 180°C, and a yarn speed of 350 m / min to produce a false-twisted crimped yarn A1 (PET SD84T36, crimp rate 20%) with a total fineness of 84 dtex / 36 fibers. The single fiber fineness of the PET long fiber contained in this yarn A1 is about 2.3 dtex.

[0085] Core yarn: False twist crimped yarn A2 Polyethylene terephthalate (matting agent content 0.3% by mass) was melt-spun at 280°C using a conventional spinning apparatus, taken up at a speed of 2,800 m / min, and wound without stretching to obtain a semi-stretched multifilament yarn. From this multifilament yarn, a false twist crimped yarn with S-direction torque and a false twist crimped yarn with Z-direction torque were produced. Specifically, stretching and false twist crimping were performed simultaneously under conditions of a draw ratio of 1.6, a false twist number of 2,500 T / m (S-direction or Z-direction), a heater temperature of 180°C, and a yarn speed of 350 m / min, to obtain two types of false twist crimped yarns with different torque directions. Next, the false twist crimped yarn with S-direction torque and the false twist crimped yarn with Z-direction torque were combined and air entangled. This air entanglement treatment is an interlace process using an interlace nozzle, and the overfeed rate is 1.0%, and the compressed air pressure is 0.3 MPa (3 kgf / cm ２ ) was used to create a composite yarn, false-twisted and crimped yarn A2 (PET SD66T72, crimp rate 28%). This yarn A2 had a total fineness of 66 dtex / 72 strands and a torque of 0 T / m, and the single fiber fineness of the PET long fiber contained in yarn A2 was approximately 0.92 dtex.

[0086] Comparative core yarns: non-crimped yarns A3 and A4. Non-crimped yarn A3 was a multifilament yarn (NY6 56T / 17) made of nylon 6 with a total fineness of 56 dtex / 17 strands. Non-crimped yarn A4 was a multifilament yarn (NY6 78T / 24) made of nylon 6 with a total fineness of 78 dtex / 24 strands. These yarns A3 and A4 were substantially free of crimps, and the single fiber fineness of the NY6 filaments contained therein was approximately 3.3 dtex.

[0087] Effect yarn: false twisted crimped yarn B1: False twisted crimped yarn B1 (PET CD84T72, crimp rate 8%) with a total fineness of 66 dtex / 72 fibers was produced under the same prototyping conditions as false twisted crimped yarn A1, except that cationic dyeable copolymerized polyethylene terephthalate (copolymerized with 5-sodium sulfoisophthalic acid, matting agent content 0.3% by mass, CD) was used instead of SD, the number of long fibers was changed, and the draw ratio was changed. The single fiber fineness of the PET long fibers contained in this yarn B1 was approximately 1.2 dtex.

[0088] Effect Yarn: False Twist Crimped Yarn B2 Polyethylene terephthalate (matting agent content 0.3% by mass, full dull (FD)) was melt-spun at 280°C using a conventional spinning apparatus, taken up at a speed of 2,800 m / min, and wound without stretching to obtain a semi-stretched multifilament yarn. This multifilament yarn has single fibers with a cross-shaped cross section. This multifilament yarn was simultaneously stretched and false-twisted using a two-heater false-twist crimping method under the conditions of a false-twist number of 2,633 T / m, heater temperatures (first heater 160°C, second heater 170°C), and a yarn speed of 140 m / min, to produce a false-twisted crimped yarn B2 (PET FD84T72, crimp rate 9.4%) with a total fineness of 84 dtex / 72 strands. Each of the PET long fibers contained in this yarn B2 has a single fiber fineness of 1.2 dtex and a cross-shaped cross section.

[0089] Effect Yarn: False Twist Crimped Yarn B3 Polyethylene terephthalate (matting agent content 0.3% by mass, full dull (FD)) was melt-spun at 280°C using a conventional spinning apparatus, taken up at a speed of 2,800 m / min, and wound up without stretching to obtain a semi-stretched multifilament yarn. This multifilament yarn has single fibers with a flat cross-sectional shape. This multifilament yarn was simultaneously stretched and false-twisted using a two-heater false-twist crimping method under the conditions of a false-twist number of 2,633 T / m, heater temperatures (first heater 160°C, second heater 170°C), and a yarn speed of 140 m / min, to produce false-twisted crimped yarn B3 (PET FD84T30, crimp rate 2.5%) with a total fineness of 84 dtex / 30 strands. Each of the PET long fibers contained in this yarn B5 has a single fiber fineness of 2.8 dtex and a flat cross section.

[0090] Comparative effect yarns: non-crimped yarns B4 and B5. As non-crimped yarn B4, a commercially available multifilament yarn (rayon 84T / 50) made of rayon and having a total fineness of 84 dtex / 50 strands was prepared. The single fiber fineness of the rayon long fiber contained in this yarn B4 was approximately 1.7 dtex. As non-crimped yarn B5, a commercially available multifilament yarn (rayon 84T / 24) made of rayon and having a total fineness of 84 dtex / 24 strands was prepared. The single fiber fineness of the rayon long fiber contained in this yarn B5 was 3.5 dtex. The rayon long fiber contained in each of yarns B4 and B5 was substantially not crimped.

[0091] As shown in Table 1, in combinations (each of Examples 1 to 9 and Comparative Examples 10 and 11) in which any one of the aforementioned yarns A1 to A4 was used as the core yarn and any one of the aforementioned yarns B1 to B5 was used as the effect yarn, the mohair yarn produced in each wale, except for the rightmost and leftmost wales, through steps S1 to S5 in the aforementioned mohair yarn manufacturing method when n = 4 or more was used was adopted as the mohair yarn for the Examples or Comparative Examples. In other words, all of the mohair yarns produced as prototypes were mohair yarns including a single chain-knitted core yarn and multiple effect yarns held by this core yarn. In these prototypes, the core yarn and the effect yarns were not heat-sealed. Micrographs of the mohair yarns are shown in Figure 14A for Example 4, Figure 14B for Example 5, Figure 14C for Example 6, Figure 14D for Example 7, Figure 14E for Example 8, Figure 14F for Example 9, Figure 14G for Comparative Example 10, and Figure 14H for Comparative Example 11, respectively. For each of the mohair yarns produced as prototypes, the single fiber fineness of each long fiber contained in each of the core yarn and effect yarn used, and the ratio (height T1 / height T2) of each long fiber contained in the effect yarn measured by the above-mentioned method are shown in Table 1 below.

[0092]

[0093] For each of the mohair yarns according to the experimental Examples 1 to 9 and Comparative Examples 10 and 11, the height T1, height T2, and curvature radius of each long fiber contained in the effect yarn were measured, and the distance between the fixing parts of the effect yarn in the core yarn was also measured. The results are shown in Table 2 below.

[0094]

[0095] For each of Examples 1 to 9 and Comparative Examples 10 and 11, mesh knitted fabrics having the structures shown in Figures 15(a) and 15(b) were produced by a conventional method using only the mohair yarn produced as a material. For each of the produced knitted fabrics (fabrics consisting only of mohair yarn), the basis weight, fiber shedding rate, breathability, and heat retention were measured using the measurement methods described above, and the results are shown in Table 3 below.

[0096]

[0097] Tables 1 to 3 suggest that Examples 1 to 9 have higher heat retention rates and significantly lower fiber shedding rates than Comparative Examples 10 and 11. Compared to Comparative Example 10, Examples 1 to 9 have relatively lower basis weights (relatively lighter weights) and higher breathability.

[0098] Furthermore, for each of Examples 1 to 9 and Comparative Examples 10 and 11, seamless shirts (whole garment) in adult men's sizes were fabricated using only the mohair yarns produced as materials, in a conventional manner, and were primarily composed of mesh knit fabrics having the structures shown in Figures 15A and 15B (see Figure 15C). All of these prototype shirts were lightweight, weighing between 200g and 450g. When worn outdoors in winter, the shirts produced from the mohair yarns of Comparative Examples 10 and 11 felt warmer than commercially available shirts made from conventional fleece materials. On the other hand, the shirts produced from the mohair yarns of Examples 1 to 5 and those produced from the mohair yarns of Examples 7 to 9 felt even warmer than commercially available shirts made from conventional fleece materials when worn outdoors in winter.
