Description

[Technical field]

[0001] The present invention relates to a mohair yarn, a fabric comprising the mohair yarn, and a clothing product comprising the fabric. [Background technology]

[0002] A mohair yarn is a fiber material including a core yarn and a decorative yarn held by the core yarn. Compared to a yarn consisting of only a core yarn, a mohair yarn has a thick and fluffy appearance in which the decorative yarn is fluffy and bulky so as to cover the core yarn. Due to this characteristic appearance, the mohair yarn is also called a chenille yarn. Generally, mohair yarn is used as a decorative thread for the collars of fashion clothing, and is often sold in craft stores as an embroidery thread or hand-knitted thread.

[0003] Patent Document 1 discloses a molle yarn using a twisted yarn of a core yarn and a presser yarn. In this molle 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 crimping can improve the bulkiness of the molle yarn, and that the molle yarn can be suitably used as a stuffing. [Prior art documents] [Patent documents]

[0004] [Patent Document 1] Patent Publication No. 2022-13788 [Patent Document 2] Japanese Patent Application Publication No. 4-352840 Summary of the Invention [Problem to be solved by the invention]

[0005] On the other hand, in general, in the case of mohair yarn, there is a problem that the flower yarn is easily removed from the core yarn by washing. In the part where the flower yarn has fallen off, the core yarn is exposed, and the bulky and fluffy appearance caused by the flower yarn is damaged. For this reason, for example, it has not been very preferable to use mohair yarn in applications such as manufacturing clothes that are washed repeatedly on a daily basis, or manufacturing fabrics that are used as materials for such clothes. In addition, marine pollution by microplastics has become a problem in recent years. In consideration of these points, when using synthetic resin fibers as the flower yarn of the mohair yarn, it is desirable that the flower yarn is less likely to fall off from the core yarn even if the fabric or clothing containing the mohair yarn is washed. In addition, in general, in clothing, the higher the bulk, the greater the advantage of increased heat retention, but on the other hand, problems such as increased weight and sweatiness are likely to occur. It is desirable to eliminate these problems and manufacture clothing that is as comfortable to wear as possible.

[0006] Therefore, an object of the present invention is to provide a mohair yarn that is lightweight, has heat-retaining properties and breathability, and is easy to manufacture into a fabric in which falling off of decorative threads is suppressed, and to provide said fabric and a clothing product. [Means for solving the problem]

[0007] In order to solve the above problems, the mall yarn according to one embodiment is A mall yarn including a core yarn and a plurality of effect yarns held by the core yarn, The core yarn comprises a plurality of first long fibers, each of which has a single fiber fineness of 0.3 dtex or more and 5.0 dtex or less; Each of the effect filaments comprises a plurality of second long filaments and has a fixed portion held by the core filament, each of the second long filaments having a single filament fineness of 0.3 dtex or more and 8.0 dtex or less, When the longitudinal direction of the mortise yarn and the longitudinal directions of the respective effect yarns are oriented horizontally, a linear distance between the core yarn and a tip of each of the second long filaments is defined as a height T1 of each of the second long filaments, and further, when each of the second long filaments is stretched so as to be linear in a direction perpendicular to the longitudinal direction of the mortise yarn, a linear distance between the core yarn and a tip of each of the second long filaments is defined as a height T2 of each of the second long filaments. The ratio of the height T1 to the height T2 (the height T1 / the height T2) is 0.88 or more.

[0008] Such a molle yarn is likely to have a bulky appearance and heat retention due to the multiple filaments. In addition, since each second long fiber has the above-mentioned single fiber fineness and the above-mentioned ratio (the height T1 / the height T2) is 0.88 or more, when the molle yarn is observed under a microscope, it appears as if each of the relatively thin second long fibers stands up from the core yarn, and the multiple filaments are likely to be lightweight and breathable. Furthermore, since each of the first long fibers included in the core yarn has the above-mentioned single fiber fineness, each of the filaments is unlikely to fall off the core yarn.

[0009] A fabric according to an embodiment may include the mohair yarn. A clothing product according to an embodiment may include the fabric. Effect of the Invention

[0010] As described above, according to the present invention, it is possible to provide a mohair yarn that is lightweight, has heat-retaining properties and breathability, and is easy to manufacture into a fabric in which falling off of decorative yarns is suppressed, and the fabric and clothing product can be provided.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS

[0012] The mohair yarn according to the present invention is a fiber material including at least one core yarn and a plurality of decorative yarns held by the at least one core yarn. The plurality of decorative yarns included in the mohair yarn may be a plurality of relatively short decorative yarns (a plurality of fragmented decorative yarns) formed by cutting one or more relatively long decorative yarns during the manufacturing process of the mohair yarn.

[0013] Although not shown, the mall yarn according to the present invention may include two or more core yarns. For example, when the mall 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 which a part of the flower yarn is sandwiched between the two core yarns. For example, when the mall yarn according to the present invention includes three core yarns, the three core yarns may be twisted together to form a triplet yarn in which a part of the flower yarn is sandwiched between the three core yarns. If necessary, two or more core yarns having the same constituent resins, etc. may be used, or two or more types of 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 the remaining core yarns may be called a pressing yarn. The flower yarn may be called a feather yarn.

[0014] <Embodiment 1> Hereinafter, in this specification, examples of embodiments will be described with reference to several drawings. In each drawing, the same or similar parts are given the same or similar reference numerals. In addition, in this specification, the mall yarn 10a according to the embodiment 1 shown in FIG. 1 will be mainly described, but the present invention is not limited to this one embodiment of the mall yarn 10a.

[0015] The mall yarn 10a includes one chain-knitted core yarn 20 and a plurality of effect yarns 30a held by the single 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.

[0016] The core yarn 20 is a multifilament yarn including a plurality of first long fibers. Each of the first long fibers included in the core yarn 20 is made of a synthetic resin, and therefore is more stretchable and dries faster than staple fibers such as wool. For the same reason, the core yarn 20 has superior tensile strength, is less susceptible to yarn breakage, and is easier to handle than spun yarns spun from staple fibers.

[0017] Each of the first long fibers contained 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 unlikely to become worn down even when heated during cleaning or the like. 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-aramids (e.g., polycondensates of p-phenylenediamine and terephthalic acid chloride), and meta-aramids (e.g., polycondensates of m-phenylenediamine and isophthalic acid chloride).

[0018] Each of the first long fibers contained in the core yarn 20 is preferably a polyester fiber from the viewpoints of shrink resistance when washed, quick drying, and ease of crimping. The polyester constituting the polyester fiber is a polycondensation product of a polyvalent carboxylic 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 fiber or polyester fiber, or may be a conjugate fiber made of two or more polymers from the viewpoint of ease of crimping.

[0019] From the viewpoints of converting alkaline sweat into weak acidity when coming into contact with the sweat, thereby inhibiting the growth of bacteria, reducing the ammonia odor of sweat, and making it easier to remove dirt from the fiber surface during washing, it is preferable that each of the first long fibers contained in the core yarn 20 is a polyester-based fiber copolymerized with an ester-forming sulfonic acid metal salt compound represented by the following chemical formula 1 and / or an ester-forming sulfonic acid phosphonium salt compound represented by the following chemical formula 2.

[0028] From the viewpoint of reducing the environmental load 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-based fiber.

[0029] 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 the 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.

[0030] From the viewpoint of preventing the core yarn 20 from becoming worn out and easily maintaining the state in which the effect yarn 33 is held, the single fiber fineness of each of the first long filaments 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 filaments is less than 0.3 dtex, the first long filaments are too thin and easily broken, so that the core yarn becomes worn out and is not practical. From the viewpoint of preventing the effect yarn 33 from falling off the core yarn 20, the single fiber fineness of each of the first long filaments 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 filaments exceeds 5.0 dtex, the problem of the effect yarn falling off during washing is easily noticeable. 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 easily entangled with each other, and thus the effect yarn 33 is less likely to fall off from the core yarn 20 due to the entanglement with each other.

[0031] 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.

[0032] 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 of easily producing a lightweight and highly breathable fabric.

[0033] From the viewpoint of holding the effect yarn 30 so as not to fall off, the core yarn 20 is preferably a multifilament yarn that has been false-twisted and crimped. The crimp rate of the core yarn 20 when crimped 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 yarn 33 so as not to fall off and making it easier to produce a fabric with a soft texture. The crimp rate of the core yarn 20 when crimped 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 with little unevenness by suppressing the resilience of the core yarn 20 from being too strong.

[0034] 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.

[0035] When the core yarn 20 is false-twisted and has crimps, it is preferably a false-twisted crimp-textured yarn. False-twisted crimp-textured yarn has a torque in the S-direction or Z-direction depending on the direction of twisting. Examples of false-twisted crimp-textured yarn include so-called one heater false-twisted crimp-textured yarn in which the false twist is set in the first heater region, and so-called second heater false-twisted crimp-textured yarn in which the torque is reduced by further introducing the yarn into the second heater region and subjecting it to a relaxation heat treatment.

[0036] Each of the filaments 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 filaments 33 may be a polyamide fiber or a polyester fiber from the viewpoint of being resistant to sagging even when heated during cleaning or the like. Each of the second long fibers is preferably a polyester fiber from the viewpoint of being resistant to shrinkage when washed, being quick to dry, and being easy to give shrinkage. The filaments 33 may be a fiber group including one type of second long fiber having the same constituent polymer, or may be 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 among the polymers described above in the description of the first long fiber included in the core yarn 20, but is preferably a conjugate fiber including two or more types of polymers from the viewpoint of making the filaments 33 have a bulky appearance. Since conjugate fibers tend to have crimps, when the filaments 33 are made up of a group of conjugate fibers, each of the conjugate fibers tends to have a bulky appearance due to the crimps of the individual conjugate fibers.

[0037] Each of the second long fibers contained in the effect yarn 33 may be a long fiber having a general circular cross section, but is preferably a long fiber having an irregular cross section (long fiber having a non-circular cross section). For example, the above-mentioned conjugate fiber or fibers having various irregular cross sections such as a cross-shaped, Y-shaped or W-shaped cross section can be used as each of the second long fibers. When a long fiber having an irregular cross section is used as each of the second long fibers in the mohair yarn 10a, when a plurality of such long fibers are bundled together, the long fibers are not likely to be crowded together due to the shapes of the projections and recesses, grooves, etc. formed on each long fiber, and a relatively large inter-fiber space is formed, which is preferable from the viewpoint that the fabric made of the mohair yarn 10a can easily exhibit heat retention, sweat absorption, quick-drying properties, and dry touch (smooth feel on the skin and cool feel) due to the inter-fiber space. Furthermore, compared with long fibers with circular cross sections, long fibers with irregular cross sections are preferred from the viewpoint that they are more likely to be caught and entangled with the first long fibers included in the core yarn 20 due to unevenness, grooves, and the like 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 that changes in shape along the fiber axis direction.

[0038] A preferred example of the hollow fiber is a polyester fiber having a hollow portion formed in the center of the cross section and a plurality of protrusions arranged radially around the hollow fiber, as shown in Fig. 2(a). This hollow fiber (Fig. 2(a)) is preferable in that it has excellent heat retention, sweat absorption, and quick drying properties because a relatively large inter-fiber space is easily formed by the eight protrusions of each hollow fiber when a plurality of hollow fibers are bundled together, and is considerably lighter than a fiber having a circular cross section with the same fiber diameter due to the eight protrusions and hollow portions. A preferred example of the flat fiber is a polyester fiber having a substantially flat fiber cross section, as shown in Fig. 2(b), in which three grooves are formed by four convex portions on each of one side of the fiber and the other side of the fiber. This flat fiber (Fig. 2(b)) is superior to fibers with a circular cross section in that when multiple flat fibers are bundled together, the convex parts of each flat fiber form relatively large inter-fiber spaces, and the absorbed sweat (moisture) is easily diffused by the grooves, making it quick-drying, and since it is generally flat, it is also excellent in anti-see-through properties, and the fiber is easily bent and exhibits unique flexibility and drapeability, making it preferable. A preferred example of the false-twisted crimped fiber described above is a false-twisted crimped fiber, as shown in Fig. 2(c), in which a polyester fiber having grooves formed on the sides of the fiber is false-twisted and crimped, so that the cross section of the fiber where the grooves are formed changes in shape irregularly along the fiber axis. This false twisted, crimped fiber ( FIG. 2( c )) has an irregular fiber cross section compared to a fiber with a circular cross section. When a plurality of false twisted, crimped fibers are bundled together, large spaces are formed between the fibers, which results in excellent lightness, sweat absorption, quick drying properties, and a dry touch. In addition, the irregular fiber cross section has unevenness and grooves that make it easy for the fibers to become entangled with each of the first long fibers and difficult for them to fall off from the core yarn 20, which is preferable from the viewpoint of excellent washing resistance.

[0039] From the viewpoints of suppressing the growth of bacteria, reducing the ammonia odor of sweat, and facilitating removal of dirt from the fiber surface during washing, each of the second long fibers contained in the effect yarn 33 is preferably a polyester-based fiber copolymerized with an ester-forming sulfonic acid metal salt compound represented by the above-mentioned chemical formula 1 and / or an ester-forming sulfonic acid phosphonium salt compound represented by the above-mentioned chemical formula 2. 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 yarn 33 is preferably a chemically recycled or material recycled polyester-based fiber.

[0040] From the viewpoint of forming the fancy yarn 33 having a fluffy and bulky appearance to some extent and enhancing heat retention, the single fiber fineness of each of the second long fibers contained in the fancy 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 fiber is less than 0.3 dtex, each of the second long fibers is too thin and prone to sagging, so that the second long fibers tend to lie along the longitudinal axis of the chain-knitted core yarn 20, making it difficult to fluff the fancy yarn. From the viewpoint of preventing the fancy yarn 33 from falling off the core yarn 20, the single fiber fineness of each of the second long fibers contained in the fancy 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 fiber exceeds 8.0 dtex, the fancy yarn is prone to falling off by washing. It is considered that when each of the second long filaments contained in the effect yarns 33 has a single fiber fineness of 8.0 dtex or less, the second long filaments have a thickness that allows them to be easily entangled with each of the first long filaments contained in the core yarn 20, and the effect yarns 33 are unlikely to fall off from the core yarn 20 due to the entanglement with each other.

[0041] The second long filaments included in each of the effect yarns 33 may be in a state in which the spaces between the second long filaments are somewhat open as shown in Fig. 1. The single filament fineness of each of the effect yarns 33, which can be calculated as the sum of the single filament finenesses of the 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 making the effect yarn 33 have a fluffy and bulky appearance to some extent. The single filament fineness of each of the effect yarns 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.

[0042] From the viewpoint of forming the filament yarn 33 having a fluffy and bulky appearance to enhance heat retention, each of the second long fibers contained in the filament 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 fiber 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 of the second long fibers has excessive crimp, the second long fibers may be entangled with each other more than necessary, which may easily cause lumps or unevenness in the fabric made from the mohair yarn, and may impair heat retention to some extent. From the viewpoint of imparting crimp so as to facilitate heat retention, the radius of curvature indicating the magnitude of crimp in each of the second long fibers contained in the filament 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 crimp textured 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 multiple crimped long filaments contained in the false twisted crimp textured yarn can be treated as multiple second long filaments.

[0043] In this specification, the radius of curvature is a measured value of the radius of the curved shape formed by the sampled long fiber 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 fiber from 10 locations randomly selected at regular intervals in the direction X along the longitudinal direction of the mall yarn 10a, and observing each of the sampled long fiber 34 with a microscope at a magnification that allows confirmation of the crimp form. Using the observed image, the radius of the curved shape formed by the crimped long fiber is measured 10 or more times, and the average of the measured values ​​is regarded as the radius of curvature of the long fiber.

[0044] As shown in Fig. 1, Fig. 4 and Fig. 7(a), in the mohair yarn 10a, a part of each of the effect yarns 33 (plurality of second long filaments) is sandwiched and fixed in a loop 25 formed by chain stitching and squeezed in one core yarn 20, thereby forming a fixed part 37 in each of the effect yarns 33. That is, the fixed part 37 is in a state where a part of each of the effect yarns 33 (plurality of second long filaments) is wound around and compressed by the core yarn 20 and fixed between the core yarns 20. Moreover, Fig. 7(b) shows a plurality of effect yarns 30a in a state where the core yarn 20 is removed from the mohair yarn 10a shown in Fig. 7(a) in order to explain the positional relationship of each of the effect yarns 33 in the mohair yarn 10a. The remaining portion of each of the effect yarns 33 (plurality of second long filaments) not forming the fixed portion 37 is in a state in which each of the second long filaments extends from the fixed portion 37 in the circumferential direction of the core yarn 20 as if blooming out to some extent, forming a wing portion, or is in a state in which the second long filaments are pulled between two fixed portions 37 and bundled together with the core yarn 20 to form a composite portion 40 ( FIG. 7( a )).

[0045] From the viewpoint of facilitating the production of a fabric with excellent heat retention, in which each of the effect yarns 33 has a somewhat bulky appearance, the height T1 of each of the second long filaments 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 of the second long filaments 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 of the second long filaments listed here is the shortest linear distance between the core yarn 20 and the tip (35a or 35b) of each of the second long filaments when the longitudinal direction of the mall yarn 10a and the longitudinal direction of each of the effect yarns 33 (each of the second long filaments) are aligned horizontally (on the XY plane in FIG. 4) as shown in FIG. 4. In this case, the longitudinal direction of the mohair yarn 10a is oriented in a direction X that is along any one of the horizontal XY planes. 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 no external force (e.g., traction force) is applied to each second long filament and the second long filament is lying on the horizontal XY plane.

[0046] From the viewpoint of easily producing 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 (35a or 35b) of each second long filament when the longitudinal direction of the mohair 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 a direction Y perpendicular to the direction X along the longitudinal direction of the mohair 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 each second long filament is stretched by application of an external force (e.g., a traction force) so as to become linear in a direction Y perpendicular to the direction X along the longitudinal direction of the mohair yarn on a horizontal XY plane.

[0047] From the viewpoint of easily producing a fabric having 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 (height T1 / height T2) of each second long filament is 0.88 or more, the mohair yarn 10a has an appearance in which a plurality of second long filaments contained in the effect yarn 33 stand up from the core yarn 20, when observed under a microscope. 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 the ratio, the more each second long filament will lie in the direction X along the longitudinal direction of the mohair yarn, and the more the air flow passing through in the perpendicular direction Y will be hindered by the effect yarns (plurality of second long filaments), resulting in a loss of breathability of the fabric containing the mohair yarn.

[0048] 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 along the horizontal direction, and a woven yarn is placed on the black paper. The core yarn is attached to the black paper so that the longitudinal direction of the woven yarn is generally linear to prepare a sample. When attaching the core yarn, care is taken not to attach the second long filament to the black paper. If any decorative yarn is entangled with the core yarn, the decorative yarn is untangled from the core yarn and then the core yarn is attached to the black paper to prepare a sample. The sample is photographed at 10 points using a microscope at a magnification of 50 times, and the linear distance between the core yarn 20 and the tip (33a or 33b) of the second long filament is measured for each second long filament using the photographed images at the 10 points, as shown in FIG. 4. The linear distance is measured for 50 second long filaments, and the average value is taken as the height T1 of each second long filament.

[0049] The height T2 of each second long filament in this specification is a value obtained by the following method. In the sample after the calculation of the value of the height T1, the same 50 second long filaments as those for which the linear distance for calculating the height T1 was measured are pinched at their tip (33a or 33b) and pulled in a direction Y perpendicular to the direction X along the longitudinal direction of the mall yarn so as to be stretched in a straight line, and the tip (33a or 33b) of the second long filament is attached to a black paper. The sample is in a state where the second long filament is held on the black paper in a linearly stretched state. The sample is observed under a microscope at a magnification of 50 times to measure the linear distance between the core yarn 20 and the tip (33a or 33b) of the second long filament for each of the attached 50 second long filaments. The linear distance is measured for each of the 50 second long filaments, and the average value is taken as the height T2 of each of the second long filaments.

[0050] The present inventors have found that when a certain number of effect yarns 33 are held by a core yarn 20 of a certain length, the effect yarns 33 are more unlikely to fall off the core yarn 20. It is presumed that when the fixing parts 37 of the effect yarns 33 sandwiched between the core yarns 20 reach a certain thickness or more, the core yarn 20 is compressed by the thickness of the fixing parts 37, and the fixing parts 37 are more likely to be stably held between the core yarns 20. From this viewpoint, in the direction X along the longitudinal direction of the mall yarn 10a, the interval between the fixing parts 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 fixed parts 37 where 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 more preferably 21.2 parts / inch or more.

[0051] In addition, if too many fancy yarns 33 are held for a certain length of core yarn 20, the core yarn 20 is excessively pressed by the excessive number of fixing parts 37, and some of the fancy yarns 33 are likely to be pushed out from between the core yarns 20. In other words, it is presumed that the core yarn 20 has an upper limit for stably holding the fancy yarns 33, and if the core yarn 20 holds the fancy yarns 33 in excess of the upper limit, some of the fancy yarns 33 are likely to fall off the core yarn 20 depending on the amount of the excess. In addition, in order to make the texture of the fabric made using the mall yarn 10a soft, it is desirable that the core yarn 20 is not too pressed and is somewhat flexible. From these points of view, the interval between the fixing parts 37 in the direction X along the longitudinal direction of the mall 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.

[0052] 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 by attaching the mohair yarn 10a to a black paper in such a manner that the direction X along the longitudinal direction of the mohair yarn 10a is horizontal as a whole, and by unwinding 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 the sample at 10 points with a microscope at a magnification of 50 times.

[0053] As shown in Figs. 1, 4, 7(a) and 7(b), in the mortise yarn 10a, each of the effect yarns 33 is held by the core yarn 20 so that two fixing parts 37 are formed in each of the effect yarns 33. That is, a plurality of narrowed loops 25 are formed in the core yarn 20, and each of the effect yarns 33 (a plurality of second long fibers) passes through two of the loops formed in the core yarn in the middle of the longitudinal direction of the fiber, and is fixed in each of the narrowed loops 25. In this way, in the mortise yarn 10a, each of the effect yarns 33 has two fixing parts, so that each of the effect yarns 33 is strongly held by the core yarn 20 and is less likely to fall off from the core yarn 20, compared to an effect yarn in which only one fixing part is formed. Also, as described above, the part between the two fixing parts 37 in each of the effect yarns 33 is bundled with the core yarn 20 to form a composite part 40. In this composite portion 40, the multiple first long fibers contained in the core yarn 20 and the multiple second long fibers contained in each of the effect yarns 33 are likely to be somewhat entangled, which is also considered to make each of the effect yarns 33 in the mohair yarn 10a less likely to fall off from the core yarn 20.

[0054] 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 having a bulky appearance and heat retention from 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 having a relatively light weight and high breathability from the mohair yarn 10a.

[0055] Each of the effect yarns 33 may be fusion-fixed to the core yarn 20 at one or more portions selected from the fixed 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 in the core yarn 20. In addition, 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 in 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.

[0056] However, when a fabric is made 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. For this purpose, for example, the plurality of first long fibers contained in the core yarn 20 and the plurality of second long fibers contained in the effect yarn 33 are preferably made of polyester-based fibers having a melting point of 150° C. or higher.

[0057] The method for producing the mohair yarn 10a is not particularly limited, and a person skilled in the art can produce it by a normal method (for example, see 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 at this time, 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.

[0058] The above-mentioned manufacturing method will be described with reference to Fig. 5 and Fig. 6 as an example 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.

[0059] 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 wale, the core yarn 20a that has not yet been chain knitted and the first long effect yarn 31 that has not yet been cut are overlapped, and a loop 25a1 in which the core yarn 20a and the first long effect yarn 31 overlap is knitted. In the second wale 50b, which is adjacent to the right of the first wale 50a, a loop 25b1 in which the core yarn 20b and the second long effect yarn 32 that has not yet been cut are overlapped is knitted in the same manner. Meanwhile, in the third wale 50c, which is adjacent to the right of the second wale 50b (the rightmost wale), a loop 25c1 is knitted only with the core yarn 20c.

[0060] In the next step S2, in the first wale 50a on the far left side, 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 only of 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) in which the core yarn 20b and the second long effect yarn 32 formed in the "previous process" overlap to the third wale 50c on the right, and the core yarn 20b is overlapped with the first long effect yarn 31 stretched from the 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 in which 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", 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", knitting 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.

[0061] In the next step S3, in the third wale 50c located at the far right side, only the second long effect yarn 32 is stretched from the loop 25c2 formed in the immediately preceding step S2, in which the core yarn 20c and the second long effect yarn 32 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 only of 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 overlapped with the first long effect yarn 31 stretched from the second wale 50b on the right side. The core yarn 20a is passed through the loop 25a2 formed in the immediately preceding step S2, and a new loop 25a3 in which the core yarn 20a and the first long effect yarn 31 overlap is knitted.

[0062] Although not shown, in the next step S4, the above-mentioned steps S2 and S3 are alternately repeated multiple times. As a result, while each wale (50a, 50b, and 50c) chain-knits one core yarn (20a, 20b, or 20c), the first long effect yarn 31 alternately bridges the left adjacent core yarn 20a and the right adjacent core yarn 20b so as to be entangled therewith, and similarly, the second long effect yarn 32 alternately bridges the left adjacent core yarn 20b and the right adjacent core yarn 20c. When the second or subsequent steps S2 are performed in step S4, the "previous step" in step S2 refers to the step S3 performed immediately before.

[0063] After the core yarns (20a, 20b, and 20c) and the first long floral thread 31 and the second long floral thread 32 are knitted through the above-mentioned steps S1 to S4, step S5 shown in FIG. 6 is performed. In this step S5, the part of the first long floral thread 31 bridging the core yarn 20a and the core yarn 20b is cut at the intermediate position 55a between the first wale 50a and the second wale 50b. By cutting, one first long floral thread 31 becomes a plurality of relatively short floral threads 30a (a plurality of fragmented floral threads). Similarly, at the intermediate position 55b between the second wale 50b and the third wale 50c, the part of the second long floral thread 32 bridging the core yarn 20b and the core yarn 20c is cut to form a plurality of relatively short floral threads 30a (a plurality of fragmented floral threads) from one second long floral thread 32. In addition, 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.

[0064] In the above-mentioned step S5, FIG. 6 shows an example in which the first long flower thread 31 and the second long flower thread 32 are cut, and then the loops (25b1, 25b2, and 25b3) are squeezed to form the mall thread 10a. Alternatively, from the viewpoint of making the mall thread 10a easier to produce, it is preferable to squeeze the loops (25b1, 25b2, and 25b3) in the above-mentioned step S4 or step S5 to hold the first long flower thread 31 and the second long flower thread 32 with the core thread 20b, and then cut the first long flower thread 31 and the second long flower thread 32 to form the mall thread 10a. In addition, in FIG. 5 and FIG. 6, the manufacturing method of the mall thread 10a in the case of n=3 is described, but the larger the number of n, the more mall threads 10a can be simultaneously produced, which is preferable. When n is 4 or more, one mall thread 10a can be produced for each wale, except for the first wale on the leftmost side and the nth wale on the rightmost side. That is, (n-2) mohair yarns 10a can be produced at the same time. 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 portion of the first long effect yarn 31 and the cut portion of 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 parts 37 are formed per 0.25 inch in the direction X along the longitudinal direction of the mohair yarn 10a (24 parts / inch), that is, the interval D between the fixing parts 37 in this case is 1 / 24 inch.

[0065] 5 and 6, in the mohair yarn 10a formed, for example, in the second wale 50b, a composite portion 40 in which each of the effect yarns 33 is bundled with the core yarn 20 is connected in the direction X along the longitudinal direction of the mohair yarn 10a, as shown in Fig. 7(a). In Fig. 7(a), each of the effect yarns 33 with their tips (35a and 35b) facing the upper side (one side) of the paper with respect to the core yarn 20 originates from the first long effect yarn 31. In Fig. 7(a), the effect yarns 33 with their tips (35a and 35b) facing the lower side (the other side) of the paper with respect to the core yarn 20 originates from the second long effect yarn 32. 7(b), in the mall yarn 10a, in the direction X along the longitudinal direction of the mall yarn 10a, the ornamental yarns 33 originating from the first long ornamental yarn 31 and facing the upper side (one side) of the paper and the ornamental yarns 33 originating from the second long ornamental yarn 32 and facing the lower side (the other side) of the paper are alternately connected. Therefore, for example, when the mall yarn 10a is produced using yarns with somewhat different physical properties, the first long ornamental yarn 31 and the second long ornamental yarn 32, it is possible to produce a mall 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) of the paper.

[0066] Although not shown, the fabric according to one embodiment is a fabric containing a mohair yarn 10a. For example, a woven fabric or knitted fabric containing a mohair yarn 10a can be mentioned. The fabric may be, for example, a woven fabric formed by interweaving a mohair yarn 10a with a polyester-based fiber, or a knitted fabric formed by interweaving a mohair yarn 10a with a polyester-based fiber. From the viewpoint of easily exhibiting the heat retention, light weight and breathability due to the mohair yarn 10a by containing a certain amount of the mohair yarn 10a in the fabric, the content of the mohair yarn 10a in the fabric may be, for example, higher 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 more preferable that the fabric is a woven fabric or knitted fabric substantially composed of the mohair yarn 10a. From the viewpoint of being easier to manufacture than woven fabric, it is even more preferable that the fabric is a knitted fabric made of mohair yarn 10a.

[0067] In order to make it easier for the mohair yarn 10a to exert its heat-retaining properties, 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 In order to make the fabric relatively light and highly breathable, the fabric containing the mall yarn 10a has a basis weight of, for example, 350 g / m 2 Less than 300 g / m 2 In this specification, the basis weight is a value measured according to a measurement method in accordance with 8.3 of JIS L 1096-2010.

[0068] 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.

[0069] The fiber shedding rate in this specification is a value obtained by the following method. (Method of measuring fiber shedding rate) Step 1: Three test pieces of 300 mm x 300 mm size containing synthetic fibers are obtained from a textile product such as a fabric. At this time, the test pieces are cut out to 300 mm x 300 mm size from the fabric using a flat nichrome heater type soldering iron (Ishizaki Electric Works Co., Ltd., model number: SB-100). Step 2: The mass of the obtained test piece 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 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 washing machine. Step 3: Measure the mass of the dried test piece to the nearest 0.1 μg using an electronic balance. The mass measurement of the test piece before washing is L0, and the mass measurement of the test piece after washing and drying is L1. Calculate the fiber (microplastic) shedding rate (%) from the test piece using the following formula. Dropout rate (%)=((L0-L1) / L0)×100

[0070] From the viewpoint of easily producing a textile product (e.g., clothing product) that dries quickly and does not get stuffy, it is preferable that the time for the diffusible residual moisture content of the 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 calculating it according to the following formula. Residual moisture rate (%) = Moisture content at each time (g) / Moisture content immediately after dripping (back side) (g) x 100

[0071] From the viewpoint of easily producing a textile product (e.g., a clothing product) that is highly breathable and does not easily become stuffy, the air permeability of the fabric containing the mohair yarn 10a is preferably 100 cc / (cm 2 ·sec) or more, more preferably 150cc / (cm 2 / sec) 2 In this specification, the air permeability is a value measured in accordance with JIS L 1096-2010, 8.26.1 Method A (Fragile method).

[0072] From the viewpoint of easily producing a textile product (e.g., clothing product) having 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.

[0074] <Other embodiments 2 to 8> Hereinafter, with reference to Figs. 8 to 13, mohair yarns (10b to 10g) according to other embodiments will be described. These mohair yarns (10b to 10g) each have roughly the same configuration and action and effect as the mohair yarn 10a (Fig. 7(a)) described above. Explanations of the points in common with the mohair yarn 10a will be largely omitted, and differences will be mainly described.

[0075] The mall yarn 10b according to the second embodiment shown in FIG. 8(a) includes one chain-knitted core yarn 20 and multiple flower yarns 30b held by the core yarn 20. Each of the multiple flower yarns 30b includes two fixed parts 37 sandwiched within a loop 25 formed in the core yarn 20 and squeezed. The mall yarn 10b can be manufactured in the third wale (n-th wale) in the manufacturing method (where n=3) described with reference to FIG. 5 and FIG. 6. That is, each flower yarn 33 in the mall yarn 10b can be derived from the second long flower yarn 32, and both the first tip 35a and the second tip 35b face the upper side (one side) of the paper in FIG. 8(a). On the other hand, the mall yarn 10b does not include a flower yarn whose tip faces the lower side (the other side) of the paper in FIG. 8(a). In FIG. 8(b), in order to explain the positional relationship of each of the effect yarns 33 in the mohair yarn 10b, a plurality of effect yarns 30b are shown in a state in which the core yarn 20 is removed from the mohair yarn 10b shown in FIG. 8(a) (the relationship between (a) and (b) in FIG. 8 is the same as the relationship between (a) and (b) in each of FIG. 9 to FIG. 13 described below). As is clear from FIG. 8(a) and FIG. 8(b), in the direction X along the longitudinal direction of the mohair yarn 10b, a composite part 40 in which the core yarn 20 and each effect yarn 33 are bundled, and a part consisting only of the core yarn 20 are alternately and repeatedly connected. The mohair yarn 10b has a bulky appearance due to the effect yarns 33 on the upper side (one side) of the paper, but is lighter than the above-mentioned mohair yarn 10a (FIG. 7(a)) because there is no effect yarn on the lower side (the other side) of the paper.

[0076] The mall yarn 10c according to the third embodiment shown in FIG. 9(a) includes one chain-knitted core yarn 20 and multiple flower yarns 30c held by the core yarn 20. Each of the multiple flower yarns 30c includes two fixed portions 37 sandwiched within a loop 25 formed in the core yarn 20 and drawn. Compared to the above-mentioned mall yarn 10b (FIGS. 8(a) and 8(b)), the mall yarn 10c (FIGS. 9(a) and 9(b)) is generally configured in the same manner, 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 flower yarns 33 on both the upper side (one side) and the lower side (the other side) of the paper, and is lightweight due to the smaller amount of flower yarns 33 compared to the above-mentioned mall yarn 10a (FIGS. 7(a) and 7(b)).

[0077] The mall yarn 10d according to the fourth embodiment shown in FIG. 10(a) includes one chain-knitted core yarn 20 and multiple flower yarns 30d held by the core yarn 20. Each of the flower yarns 33 included in the multiple flower yarns 30d has two fixed parts 37 sandwiched within a loop 25 formed in the core yarn 20 and squeezed. As shown in FIG. 10(b), in each flower yarn 33 in the mall yarn 10d, the first tip 35a faces the upper side (one side) of the paper and the second tip 35b faces the lower side (other end side) of the paper. Compared with the mall yarn 10a described above (FIGS. 7(a) and 7(b)), the mall yarn 10d is likely to have substantially uniform characteristics such as softness and texture between the upper side (one side) and the lower side (other side) of the paper even if the physical properties of the first long flower yarn and the second flower yarn used in the manufacturing process are different.

[0078] The mall yarn 10e according to the fifth embodiment shown in Fig. 11(a) 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 passes through three of the multiple loops formed and drawn in the core yarn to form three fixed parts 37 (Fig. 11(b)), and both the first tip 35a and the second tip 35b face the upper side (one side) of the paper. In the direction X along the longitudinal direction of the mall yarn 10e, a composite part 40 in which each effect yarn 33 is bundled with the core yarn 20 and a part of only the core yarn 20 are alternately and repeatedly connected. In the mohair yarn 10e, each of the effect yarns 33 has three fixing parts 37, which is preferable in that the effect yarns 33 are less likely to fall off the core yarn 20 compared to the above-mentioned mohair yarn 10b (FIGS. 8(a) and 8(b)) in which each effect yarn 33 has two fixing parts.

[0079] The mall yarn 10f according to the sixth embodiment shown in Fig. 12(a) 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 parts 37 formed (Fig. 12(b)). Each effect yarn 33 in the mall yarn 10f has a first tip 35a facing the upper side (one side) of the paper and a second tip 35b facing the lower side (the other side) of the paper. Except for this point, the mall yarn 10f is configured in the same manner as the above-mentioned mall yarn 10e (Fig. 12(a)).

[0080] The mall yarn 10g according to the seventh embodiment shown in Fig. 13(a) 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 parts 37 (Fig. 13(b)). In the direction X along the longitudinal direction of the mall yarn 10g, composite parts 40 in which each effect yarn 33 is bundled with the core yarn 20 are repeatedly connected, and apart from this, the mall yarn 10g is configured in the same manner as the above-mentioned mall yarn 10e (Fig. 11(a)).

[0081] 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, more preferably three or more fixing parts formed thereon.

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 and crimped under conditions of a draw ratio of 1.6 times, 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 and 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 was about 2.3 dtex.

[0086] Core yarn: False twisted crimped yarn A2 Polyethylene terephthalate (matt agent content: 0.3% by mass) was melt spun at 280°C using a conventional spinning device, taken up at a speed of 2,800 m / min, and wound up without stretching to obtain a semi-stretched multifilament yarn. From this multifilament yarn, a false twisted crimped yarn having a torque in the S direction and a false twisted crimped yarn having a torque in the Z direction were produced. Specifically, drawing and false twisted crimping were carried out 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 twisted crimped yarns with different torque directions. Next, the false twisted crimped yarn having torque in the S direction and the false twisted crimped yarn having torque in the Z direction were combined and subjected to air entanglement. This air entanglement was an interlace process using an interlace nozzle, with an overfeed rate of 1.0% and an air pressure of 0.3 MPa (3 kgf / cm). 2 ) to give 50 entanglements / m, and false twisted crimped yarn A2 (PET SD66T72, crimp rate 28%) was produced as a composite yarn.

[0088] Flower yarn: False twisted shrink-processed yarn B1: A false twisted crimped yarn B1 (PET CD84T72, crimp rate 8%) with a total fineness of 66 dtex / 72 strands was produced under similar trial conditions, except that cationic dyeable copolymerized polyethylene terephthalate (copolymerized with 5-sodium sulfoisophthalic acid, matting agent content 0.3 mass%, CD) was used instead of SD, the number of long fibers was changed, and the draw ratio was changed, compared to false twisted crimped yarn A1. The single fiber fineness of the PET long fiber contained in this yarn B1 is about 1.2 dtex.

[0089] Flower yarn: False twisted shrink-processed yarn B2 Polyethylene terephthalate (matting agent content 0.3% by mass, full dull (FD)) was melt spun at 280°C from a normal spinning device, 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 a single fiber with a cross-shaped cross section. This multifilament yarn was simultaneously stretched and false twisted and crimped by a two-heater false twist crimping method under the conditions of false twist number 2,633 T / m, heater temperature (first heater 160°C, second heater 170°C), and yarn speed 140 m / min, to produce false twisted and crimped yarn B2 (PET FD84T72, crimp rate 9.4%) with a total fineness of 84 dtex / 72 fibers. Each PET long fiber contained in this yarn B2 has a single fiber fineness of 1.2 dtex and a cross-shaped cross section.

[0090] Flower yarn: False twisted shrink-processed yarn B3 Polyethylene terephthalate (content of matting agent: 0.3% by mass, full dull (FD)) was melt-spun at 280°C from a normal spinning device, 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 a single fiber with a flat cross-sectional shape. This multifilament yarn was simultaneously stretched and false-twisted and crimped by a two-heater false-twisting crimping method under the conditions of false-twist number of 2,633 T / m, heater temperature (first heater 160°C, second heater 170°C), and 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 fibers. Each PET long fiber contained in this yarn B5 has a single fiber fineness of 2.8 dtex and a flat cross-section.

[0091] Comparison of filaments: Non-crimped yarns B4 and B5 As the 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 about 1.7 dtex. As the 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 the yarns B4 and B5 was substantially not crimped.

[0092] As shown in Table 1, in the combination of any one of the yarns A1 to A4 described above as the core yarn and any one of the yarns B1 to B5 described above as the effect yarn (each of Examples 1 to 9 and Comparative Examples 10 and 11), the mall yarns produced in each wale, except for the rightmost wale and the leftmost wale, through steps S1 to S5 in the case of n=4 or more in the above-mentioned mall yarn manufacturing method were adopted as the mall yarns of the Examples or Comparative Examples. That is, all of the mall yarns produced as prototypes are mall yarns including one chain-knitted core yarn and multiple effect yarns held by this core yarn. In the prototypes, the core yarn and the effect yarn were not heat-sealed. Micrographs of the mall yarns of each of Examples 4 to 9 and Comparative Examples 10 and 11 are shown in FIG. 14. For each of the mall yarns produced as prototypes, the single fiber fineness of each long fiber contained in each of the core yarns and effect yarns used, and the ratio (height T1 / height T2) measured by the above-mentioned method for each long fiber contained in the effect yarn are shown in Table 1 below.

[0093] [Table 1]

[0094] For each of the prototyped mohair yarns according to 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.

[0095] [Table 2]

[0096] For each of Examples 1 to 9 and Comparative Examples 10 and 11, mesh knitted fabrics having the structure shown in Figures 15(a) and 15(b) were produced by a conventional method using only the mohair yarn produced as the material. The weight, fiber shedding rate, air permeability, and heat retention of each of the produced knitted fabrics (fabrics consisting of only mohair yarn) were measured by the measuring methods described above, and the results are shown in Table 3 below.

[0097] [Table 3]

[0098] Tables 1 to 3 suggest that the heat retention rate of the fabrics in Examples 1 to 9 is higher and the fiber shedding rate is significantly lower than those in Comparative Examples 10 and 11. Compared to Comparative Example 10, Examples 1 to 9 suggest that the basis weight is relatively low (relatively light) and the breathability is high.

[0099] In addition, for each of Examples 1 to 9 and Comparative Examples 10 and 11, a seamless shirt (whole garment) for an adult male size was produced by a conventional method using only the mohair yarn as a material, and was mainly composed of a mesh knit fabric having the structure shown in Figures 15(a) and 15(b) (see Figure 15(c)). All of these prototype shirts were lightweight, with a mass ranging from 200g to 450g. When the shirts prototyped from the mohair yarn of Comparative Examples 10 and 11 were worn outdoors in winter, they felt warm to a similar extent to commercially available shirts made of conventional fleece material. On the other hand, when the shirts prototyped from the mohair yarn of Examples 1 to 5 and the mohair yarn of Examples 7 to 9 were worn outdoors in winter, they felt even warmer than commercially available shirts made of conventional fleece material.
