Abstract
Description
[Technical Field]
[0001] The present invention relates to chenille yarn, a fabric containing the chenille yarn, and a garment product comprising the fabric. [Background technology]
[0002] Chenille yarn is a fibrous material that includes a core thread and embellishing threads held by the core thread. Compared to yarn made only of core thread, chenille yarn has a thick, fluffy appearance because the embellishing threads cover and conceal the core thread, making it bulky. Due to this distinctive appearance, chenille yarn is also called chenille yarn. Generally, chenille yarn is used as a decorative thread for collars of fashion clothing, etc., or it is often sold in craft stores as embroidery thread or knitting thread.
[0003] Patent Document 1 discloses a chenille yarn using a twisted core yarn and a binding yarn. In this chenille yarn, a decorative thread is fused and fixed between the core yarn and the binding yarn, and the decorative thread has a crimp with a radius of curvature of 0.5 mm to 5.0 mm. Patent Document 1 explains that such crimping can improve the bulkiness of the chenille yarn, making it suitable for use as a stuffing material. [Prior art documents] [Patent Documents]
[0004] [Patent Document 1] Japanese Patent Publication No. 2022-13788 [Patent Document 2] Japanese Patent Application Publication No. 4-352840 [Overview of the project] [Problems that the invention aims to solve]
[0005] On the other hand, a common problem with chenille yarn is that the decorative filaments tend to detach from the core thread during washing. Where the filaments have fallen out, the core thread is exposed, compromising the bulky, fluffy appearance created by the filaments. Therefore, using chenille yarn has traditionally been undesirable for applications such as manufacturing clothing that is repeatedly washed daily, or for manufacturing fabrics that serve as materials for such clothing. Furthermore, in recent years, marine pollution by microplastics has become a significant problem. Considering these factors, when using synthetic resin fibers as the decorative filaments in chenille yarn, it is desirable that the filaments do not easily detach from the core thread even after washing the fabric or clothing containing the chenille yarn. Additionally, while bulkier clothing generally offers the advantage of increased heat retention, it also tends to increase weight and become more prone to stuffiness. It is desirable to resolve these issues and manufacture clothing that is as comfortable as possible to wear.
[0006] Therefore, the object of the present invention is to provide a chenille yarn that is lightweight, has good heat retention and breathability, and is easy to manufacture with reduced shedding of embroidery floss, as well as the said fabric and clothing products. [Means for solving the problem]
[0007] To solve the above-mentioned problems, the chenille yarn according to one embodiment is A chenille yarn comprising a core thread and a plurality of embroidered threads held by the core thread, 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 filament consists of multiple second long fibers and has a fixed portion that is held by the core thread, and each second long fiber has a single fiber fineness of 0.3 dtex or more and 8.0 dtex or less. When the longitudinal direction of the chenille yarn and the longitudinal direction of each of the embroidered filaments are aligned horizontally, the straight-line distance between the core yarn and the tip of each of the second long fibers is defined as the height T1 of each second long fiber, and when each of the second long fibers is stretched to be straight along a direction perpendicular to the longitudinal direction of the chenille yarn, the straight-line distance between the core yarn and the tip of each of the second long fibers is defined as the height T2 of each second long fiber, in which case the ratio of height T1 to height T2 (height T1 / height T2) is 0.88 or greater.
[0008] Such chenille yarn tends to have a bulky appearance due to the multiple filaments, and it is also prone to retaining heat. Furthermore, because each second long fiber has the aforementioned single-fiber fineness and the aforementioned ratio (height T1 / height T2) is 0.88 or higher, when the chenille yarn is observed under a microscope, it appears as if the relatively thin second long fibers are rising from the core yarn, and the multiple filaments tend to be lightweight and breathable. In addition, because each first long fiber contained in the core yarn has the aforementioned single-fiber fineness, each filament is less likely to fall out of the core yarn.
[0009] A fabric according to one embodiment may include the aforementioned chenille yarn. A garment product according to one embodiment may comprise the aforementioned fabric. [Effects of the Invention]
[0010] As described above, the present invention provides a chenille yarn that is lightweight, has good heat retention and breathability, and is easy to manufacture with reduced shedding of embroidery floss, as well as the said fabric and clothing products. [Brief explanation of the drawing]

Mode for Carrying Out the Invention
[0012] The mohair yarn according to the present invention is a fiber material including at least one core yarn and a plurality of fancy yarns gripped by the at least one core yarn. The plurality of fancy yarns included in the mohair yarn may be a plurality of relatively short fancy yarns (fancy yarns that have become a plurality of fragments) formed by cutting one or more relatively long fancy yarns during the manufacturing process of the mohair yarn.
[0013] 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 is in a form including two core yarns, the two core yarns may form a double yarn twisted so that a part of the fancy yarn is sandwiched between the two core yarns. For example, when the mohair yarn according to the present invention is in a form including three core yarns, the three core yarns may form a triple yarn twisted so that a part of the fancy yarn is sandwiched between the three core yarns. If necessary, two or more core yarns having the same constituent resin or the like may be used, or two or more types of core yarns having different constituent resins or the like may be used. When using two or more core yarns, at least one of them may be called a core yarn, and the remaining at least one may be called a holding yarn. The fancy yarn may be called a downy yarn.
[0014] <Embodiment 1> Hereinafter, examples of embodiments will be described with reference to several figures. In each figure, the same or similar parts are denoted by the same or similar reference numerals. Furthermore, although this specification mainly describes the chenille yarn 10a according to Embodiment 1 shown in Figure 1, the present invention is not limited to this embodiment of chenille yarn 10a.
[0015] The chenille yarn 10a includes a single chain-knit core yarn 20 and a plurality of embroidered flosses 30a held by the core yarn 20. Each embroidered floss 33 included in the plurality of embroidered flosses 30a is held by the core yarn 20 in such a way that it is sandwiched and fixed by the core yarn 20.
[0016] The core yarn 20 is a multifilament yarn containing multiple first long fibers. Each first long fiber in the core yarn 20 is made of synthetic resin, and therefore stretches more easily and dries faster than short fibers such as wool. For the same reason, the core yarn 20 has superior tensile strength, is less prone to breakage, and is easier to handle than spun yarn spun from short fibers.
[0017] Each first long fiber contained in the core thread 20 is crystalline and has a relatively high melting point, and therefore, from the viewpoint of being less prone to deterioration even when heated during cleaning, etc., it may be a thermoplastic polymer produced by condensation polymerization, such as polyamide or polyester. From the viewpoint of having excellent flexibility, the first long fiber may be, for example, a polyamide fiber. Examples of polyamides that can constitute a polyamide fiber include nylon 6, nylon 66, para-aramid (e.g., a polycondensate of p-phenylenediamine and terephthalic acid chloride), or meta-aramid (e.g., a polycondensate of m-phenylenediamine and isophthalic acid chloride).
[0018] Each first long fiber contained in the core yarn 20 is preferably a polyester fiber from the viewpoint of being less prone to shrinkage when washed, drying quickly, and easily crimped. The polyester constituting the polyester fiber is a polycondensation 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, or polybutylene naphthalate. The first long fiber may be a fiber made of one polymer from among the polymers exemplified here as constituent resins of polyamide fibers or polyester fibers, or it may be a conjugate fiber made of two or more polymers from the viewpoint of easily crimping.
[0019] Each first long fiber contained in the core yarn 20 is preferably a polyester fiber copolymerized with an ester-forming metal sulfonic acid salt compound represented by the following chemical formula 1 and / or an ester-forming phosphonium sulfonic acid salt compound represented by the following chemical formula 2, from the viewpoint of converting alkaline sweat to a weakly acidic state when it comes into contact with sweat, thereby suppressing the growth of bacteria, reducing the ammonia odor of sweat, and making it easier to remove dirt from the fiber surface during washing.

[0028] From the perspective of reducing environmental impact and contributing to the realization of a sustainable society as advocated in the SDGs, it is preferable that each first long fiber contained in the core yarn 20 is a polyester fiber that has been chemically recycled or materially recycled.
[0029] The core yarn 20 may be a multifilament yarn comprising multiple first long fibers composed of one type of polymer from among the polyamide-based fibers or polyester-based fibers exemplified above, or it may be a multifilament yarn comprising multiple first long fibers of two or more types, each composed of a different polymer.
[0030] From the viewpoint of making the core thread 20 less prone to sagging and maintaining the state in which the embroidered floss 33 is held, the single fiber fineness of each first long fiber contained in the core thread 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 fiber is less than 0.3 dtex, the first long fiber is too thin and easily breaks, causing the core thread to sag easily and making it unsuitable for practical use. From the viewpoint of making the embroidered floss 33 less likely to fall out of the core thread 20, the single fiber fineness of each first long fiber 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 fiber exceeds 5.0 dtex, the problem of the embroidered floss falling out during washing is likely to become apparent. Although the mechanism is unknown, it is presumed that when the single fiber fineness of the first long fiber is 5.0 dtex or less, the first long fiber contained in the core thread 20 and the second long fiber contained in the embroidered filament 33 become thick enough to easily intertwine, and as they intertwine with each other, the embroidered filament 33 becomes less likely to fall out of the core thread 20.
[0031] In this specification, fineness is the average value obtained by measuring the mass of 100m of yarn or fiber, multiplying it by 100, and repeating this process 10 times.
[0032] The total fineness of the core thread 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 thread 20 from collapsing easily. The total fineness of the core thread 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 embroidery thread 33 from falling out of the core thread 20 and from the viewpoint of making it easy to produce a lightweight and highly breathable fabric.
[0033] From the viewpoint of gripping the embroidery floss 30 so that it does not easily fall out, it is preferable that the core yarn 20 is a multifilament yarn that has been false-twisted and crimped. The crimping rate of the core yarn 20 when crimped may be 3% or more, preferably 5% or more, and more preferably 10% or more, from the viewpoint of making it easier to grip the embroidery floss 33 so that it does not easily fall out and from the viewpoint of making it easier to produce a fabric with a soft texture. The crimping rate of the core yarn 20 when crimped may be 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, while keeping the resilience of the core yarn 20 from becoming too strong.
[0034] In this specification, the crimp rate shall be the measured value obtained by the method conforming to "8.12.2 Crimp rate and residual crimp rate" of JIS L 1015-2010.
[0035] If the core yarn 20 is a false-twisted yarn with crimp, it is preferably a false-twisted crimped yarn. A false-twisted crimped yarn has torque in the S direction or the Z direction depending on the direction of twisting. Examples of false-twisted crimped yarns include a so-called one-heater false-twisted crimped yarn in which the false twist is set in the first heater area, or a so-called second-heater false-twisted crimped yarn in which the torque is reduced by further introducing this yarn into the second heater area and performing relaxation heat treatment.
[0036] Each floss 33 is a group of fibers comprising multiple second long fibers made of synthetic resin. Each second long fiber in the floss 33 may be a polyamide fiber or a polyester fiber, from the viewpoint of being resistant to deformation even when heated during cleaning, etc. Each second long fiber is preferably a polyester fiber, from the viewpoint of being resistant to shrinkage when washed, drying quickly, and easily crimped. The floss 33 may be a group of fibers consisting of one type of second long fiber having the same constituent polymer, or it may be a group of fibers consisting of two or more types of second long fibers having different constituent polymers. Each second long fiber may be a fiber made of one type of polymer from the polymers described above in the description of the first long fiber contained in the core thread 20, but from the viewpoint of the floss 33 having a bulky appearance, it is preferable that it be a conjugate fiber made of two or more types of polymers. Because conjugated fibers tend to have crimp, when the floss 33 is composed of a group of conjugated fibers, each conjugated fiber has crimp, which tends to result in a bulky appearance.
[0037] Each second long fiber in the floral yarn 33 may be a long fiber having a general circular cross-sectional shape, but preferably it is a long fiber having an irregular cross-sectional shape (a long fiber whose cross-sectional shape is not circular). For example, the conjugate fibers mentioned above, or fibers having various irregular cross-sectional shapes such as cross-shaped, Y-shaped, or W-shaped, can be used as each second long fiber. When long fibers with irregular cross-sectional shapes are used as each second long fiber in the chenille yarn 10a, when multiple of these long fibers are bundled together, the shapes of the irregularities and grooves formed on each long fiber make it difficult for the long fibers to become densely packed together, and relatively large interfiber spaces are formed. For this reason, the fabric made from the chenille yarn 10a is preferable from the viewpoint of easily exhibiting heat retention, sweat absorption and quick drying properties, and a dry touch (a smooth and refreshing feel) due to these interfiber spaces. Furthermore, compared to long fibers with a circular cross-section, long fibers with an irregular cross-sectional shape are preferable because the irregularities and grooves formed on these long fibers make it easier for them to catch on and entangle with each of the first long fibers contained in the core yarn 20, thus preventing the embroidered filaments 33 from easily falling off the core yarn 20. From a similar viewpoint, each second long fiber is more preferably a long fiber having one or more irregular cross-sectional shapes selected from hollow fibers with a hollow portion formed in the fiber cross-section, flat fibers with a substantially flattened fiber cross-section, and false-twisted crimped fibers with a grooved fiber cross-section and a change in the shape of the fiber cross-section along the fiber axis.
[0038] A preferred example of the hollow fiber described above is a polyester fiber in which a hollow portion is formed in the center of the cross-section and multiple protrusions are arranged radially around it, as shown in Figure 2(a). This hollow fiber (Figure 2(a)) is preferable because when multiple hollow fibers are bundled together, a relatively large interfiber space is easily formed by the eight protrusions of each hollow fiber, resulting in excellent heat retention and sweat absorption / quick drying properties, and it is considerably lighter than a circular cross-section fiber with the same fiber diameter due to the eight protrusions and hollow portion. Another preferred example of the flattened fiber described above is a polyester fiber having a substantially flattened fiber cross-section, in which three grooves are formed by four convex portions on each of the fiber sides, as shown in Figure 2(b). These flat fibers (Figure 2(b)) are preferable to fibers with a circular cross-section because, when multiple flat fibers are bundled together, the convex portions of each flat fiber create relatively large interfiber spaces, resulting in excellent sweat absorption (water absorption). Absorbed sweat (moisture) is easily diffused by the grooves, resulting in excellent quick-drying properties. Furthermore, because they are roughly flat, they offer excellent opacity, and the fibers are easily bent, making them preferable in terms of exhibiting unique suppleness and drape. As a preferred example of the above-mentioned false-twist crimped fibers, as shown in Figure 2(c), false-twist crimped fibers are obtained by false-twist crimping polyester fibers in which grooves are formed on the sides of the fibers, resulting in a false-twist crimped fiber in which the shape of the fiber cross-section in which the grooves are formed changes irregularly along the fiber axis. This false-twist crimped fiber (Figure 2(c)) has an irregular fiber cross-section compared to fibers with a circular cross-section. Therefore, when multiple false-twist crimped fibers are bundled together, a large inter-fiber space is formed, resulting in excellent lightness, sweat absorption and quick-drying properties, and a dry-touch texture. Furthermore, the irregular shape of the fiber cross-section, with its unevenness and grooves, makes it easy for each first long fiber to intertwine and prevents it from falling off the core yarn 20, making it preferable from the viewpoint of excellent wash resistance.
[0039] Each second long fiber in the floral yarn 33 is preferably a polyester fiber copolymerized with an ester-forming sulfonic acid metal salt compound represented by chemical formula 1 and / or an ester-forming sulfonic acid phosphonium salt compound represented by chemical formula 2, from the viewpoint of suppressing the growth of bacteria, reducing the ammonia odor of sweat, and making it easier to remove dirt from the fiber surface during washing. Each second long fiber in the floral yarn 33 is preferably a polyester fiber that has been chemically recycled or materially recycled, from the viewpoint of reducing environmental impact and contributing to the realization of a sustainable society as advocated in the SDGs.
[0040] From the viewpoint of forming a somewhat fuzzy, bulky appearance of the floss 33 to enhance heat retention, the single fiber fineness of each second long fiber included in the floss 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 second long fiber is too thin and easily collapses, so multiple second long fibers tend to lie along the long axis direction of the chain-knitted core yarn 20, making it difficult to fluff up the floss. From the viewpoint of preventing the floss 33 from falling out of the core yarn 20, the single fiber fineness of each second long fiber included in the floss 33 is 8.0 dtex or less, 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 floss will easily fall out during washing. It is likely that if each of the second long fibers contained in the floss 33 has a single fiber fineness of 8.0 dtex or less, it will be thick enough to easily intertwine with each of the first long fibers contained in the core thread 20, and the intertwining will prevent the floss 33 from easily falling out of the core thread 20.
[0041] The multiple second long fibers contained in each floss 33 may be somewhat separated from each other, as illustrated in Figure 1. The single filament fineness of each floss 33, which can be calculated as the sum of the single filament finenesses of each second long fiber, 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 floss 33 a somewhat fuzzy and bulky appearance. The single filament fineness of each floss 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 it from easily falling out of the core yarn 20 and from the viewpoint of making a lightweight and highly breathable fabric.
[0042] From the viewpoint of forming a fluffy, bulky appearance in the floss 33 to enhance heat retention, each second long fiber included in the floss 33 may be a crimped fiber. From a similar viewpoint, the radius of curvature, which indicates the amount 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 second long fiber has excessive crimp, the second long fibers may entangle with each other more than necessary, which can easily cause lumps and unevenness in the fabric made using chenille yarn, and may impair some of the heat retention. From the viewpoint of imparting crimp to facilitate heat retention, the radius of curvature, which indicates the amount of crimp in each second long fiber included in the floss 33, may be, for example, 0.10 mm or more, preferably 0.15 mm or more. From the standpoint of easily satisfying the radius of curvature conditions mentioned here, the false-twist crimped yarn described in the explanation of the core yarn 20 may be reused as the embroidery yarn 33. When the false-twist crimped yarn is reused in this way as the embroidery yarn 33, the multiple crimped long fibers contained in it can be treated as multiple second long fibers.
[0043] In this specification, the radius of curvature is the measured value of the radius of the curved shape formed by a collected long fiber 34, as illustrated in Figure 3, using images observed two-dimensionally with a microscope. The radius of curvature is measured by randomly selecting 10 locations at regular intervals along the longitudinal direction X of the chenille yarn 10a, and collecting one second long fiber at each location by cutting or pulling it out. Each collected long fiber 34 is then observed using a microscope at a magnification that allows confirmation of the crimped shape. Using these observation images, 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 taken as the radius of curvature of the long fiber.
[0044] As shown in Figures 1, 4, and 7(a), in the chenille yarn 10a, a portion of each flower floss 33 (multiple second long fibers) is sandwiched and fixed within a loop 25 formed and tightened by chain stitch on a single core thread 20, thereby forming a fixing portion 37 on each flower floss 33. In other words, the fixing portion 37 is a state in which a portion of each flower floss 33 (multiple second long fibers) is wrapped around the core thread 20, compressed, and fixed between the core threads 20. Furthermore, Figure 7(b) shows multiple flower flosses 30a in the chenille yarn 10a with the core thread 20 removed, in order to explain the positional relationship of each flower floss 33 in the chenille yarn 10a. In each filament 33 (multiple second long fibers), the remaining portion that does not form a fixing portion 37 is either in a state where the second long fibers extend outwards from the fixing portion 37 in the circumferential direction of the core thread 20, forming a wing-like portion, or in a state where they are pulled between two fixing portions 37 and bundled together with the core thread 20 to form a composite portion 40 (Figure 7(a)).
[0045] From the viewpoint of creating a fabric with a somewhat bulky appearance and excellent heat retention, the height T1 of each second long fiber 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 creating a lightweight and highly breathable fabric, the height T1 of each second long fiber 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 fiber mentioned here is the shortest straight-line distance between the core thread 20 and the tip (35a or 35b) of each second long fiber when the longitudinal direction of the chenille yarn 10a and the longitudinal direction of each embroidery yarn 33 (each second long fiber) are oriented along the horizontal direction (when they are on the XY plane in Figure 4). In this case, the longitudinal direction of the chenille yarn 10a is oriented in a direction X that is any one direction along the horizontal XY plane. In other words, the height T1 can also be said to be the height from the core yarn 20 to the tip (35a or 35b) of each second long fiber when each second long fiber is lying on the horizontal XY plane without any external force (e.g., tensile force) being applied to it.
[0046] The height T2 of each second long fiber 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, from the viewpoint of easily producing a lightweight and breathable fabric. The height T2 of each second long fiber mentioned here is the shortest straight-line distance between the core thread 20 and the tip (35a or 35b) of each second long fiber when the longitudinal direction of the chenille yarn 10a and the longitudinal direction of each embroidered thread 33 (each second long fiber) are oriented in directions that are parallel to the horizontal direction (on the XY plane in Figure 4), and each second long fiber is stretched in a straight line along the direction Y which is perpendicular to the direction X which is parallel to the longitudinal direction of the chenille yarn 10a. In other words, height T2 can also be described as the height from the core thread 20 to the tip (35a or 35b) of each second long fiber when an external force (e.g., tensile force) is applied to each second long fiber and it is stretched so that it is in a straight line in the direction Y perpendicular to the direction X along the longitudinal direction of the chenille yarn on the XY plane along which each second long fiber is horizontal.
[0047] From the viewpoint of easily producing a fabric with excellent breathability, the ratio of the two types of heights (height T1 / height T2) for each second long fiber is 0.880 or more, for example, 0.89 or more is also acceptable, preferably 0.90 or more, and more preferably 0.91 or more. When the ratio of the heights (height T1 / height T2) in each second long fiber is 0.88 or more, when the chenille yarn 10a is observed under a microscope, it has an appearance in which multiple second long fibers contained in the embroidery filament 33 appear to be rising from the core yarn 20. In the chenille yarn 10a, this appearance, combined with the fact that each second long fiber is thin, allows air to pass through easily along the orthogonal direction Y. If the height ratio (height T1 / height T2) is less than 0.88, the lower this ratio is, the more each second long fiber will lie horizontally in the direction X, which is along the longitudinal direction of the chenille yarn. The airflow that would otherwise pass through in the perpendicular direction Y will be obstructed by the embroidery filaments (multiple second long fibers), impairing the breathability of the fabric containing the chenille yarn.
[0048] In this specification, the height T1 of each second long fiber is obtained by the following method. A sample is prepared by placing black paper on a flat table surface extending horizontally, placing chenille yarn on the black paper, and attaching the core yarn to the black paper so that the longitudinal direction of the chenille yarn is generally straight. Care is taken not to attach the second long fiber to the black paper during attachment. If there are any filaments entangled with the core yarn, the filaments are untangled from the core yarn before attaching the core yarn to the black paper to prepare the sample. This sample is photographed at 10 locations using a microscope at a magnification of 50x, and using the obtained images at 10 locations, the straight-line distance between the core yarn 20 and the tip of the second long fiber (33a or 33b) is measured for each second long fiber, as shown in Figure 4. This straight-line distance is measured for 50 second long fibers, and the average value is taken as the height T1 of each second long fiber.
[0049] In this specification, the height T2 of each second long fiber is a value obtained by the following method. In the sample after calculating the height T1 value described above, for each of the same 50 second long fibers whose straight-line distance for calculating height T1 has been measured, the tip (33a or 33b) of the second long fiber is pinched and pulled in a direction Y perpendicular to the direction X along the longitudinal direction of the chenille yarn to stretch it into a straight line, and the tip (33a or 33b) of the second long fiber is attached to black paper. The sample will be in a state where the second long fibers are held on the black paper in a straight-line stretched state. Using a microscope at a magnification of 50x, the straight-line distance between the core yarn 20 and the tip (33a or 33b) of the second long fiber is measured for each of the 50 attached second long fibers. This straight-line distance is measured for each of the 50 second long fibers, and the average value is taken as the height T2 of each second long fiber.
[0050] The inventors have found that when a certain number of embroidered flosses 33 are held by a core thread 20 of a certain length, the embroidered flosses 33 become less likely to fall out of the core thread 20. It is presumed that when the fixing portion 37 of the embroidered floss 33 sandwiched between the core threads 20 reaches a certain thickness or more, the core thread 20 is compressed by the thickness of the fixing portion 37, and the fixing portion 37 is more likely to be held stably between the core threads 20. From this viewpoint, in the direction X along the longitudinal direction of the chenille yarn 10a, the distance between the fixing portions 37 that hold the embroidered floss 33 by the core thread 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 chenille yarn 10a, the number of fixing parts 37 that grip the embroidery floss 33 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 even more preferably 21.2 parts / inch or more.
[0051] Furthermore, if too many embroidered threads 33 are held by a core thread 20 of a certain length, the core thread 20 will be excessively compressed by the excessive number of fixing parts 37, and some of the embroidered threads 33 are likely to be pushed out from between the core threads 20. In other words, there is an upper limit to the amount of embroidered threads 33 that the core thread 20 can stably hold, and if the amount of embroidered threads 33 held by the core thread 20 exceeds this upper limit, it is presumed that some of the embroidered threads 33 will easily fall off the core thread 20 in proportion to the excess amount. Also, in order to make the texture of the fabric made using the chenille yarn 10a soft, it is desirable that the core thread 20 is not compressed too much and is somewhat flexible. From these viewpoints, the spacing between the fixing parts 37 in the direction X along the longitudinal direction of the chenille 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 fixing parts 37 in the direction X along the longitudinal direction of the chenille yarn 10a may be, for example, 50 parts / inch or less, preferably 36 parts / inch or less, and even more preferably 28 parts / inch or less.
[0052] The spacing between the fixing parts 37 described above is the average value obtained by preparing a sample in which the chenille yarn 10a is attached to black paper so that the direction X along the longitudinal direction of the chenille yarn 10a is horizontal, and the flower floss 33 that is entangled with the core thread 20 is untangled so that each flower floss 33 is facing in a direction Y perpendicular to direction X. This sample is then photographed at 10 locations using a microscope at a magnification of 50x, and the spacing between adjacent fixing parts 37 is measured using the obtained images from the 10 locations.
[0053] As shown in Figures 1, 4, 7(a), and 7(b), in the chenille yarn 10a, each floss 33 is held by the core yarn 20 such that two fixing parts 37 are formed on each floss 33. In other words, multiple constricted loops 25 are formed on the core yarn 20, and each floss 33 (multiple second long fibers) passes through two of the loops formed on the core yarn at some point along the longitudinal direction of the fiber, and is fixed within each constricted loop 25. Thus, in the chenille yarn 10a, since each floss 33 has two fixing parts, each floss 33 is held more strongly by the core yarn 20 and is less likely to fall off the core yarn 20 compared to a floss with only one fixing part. Furthermore, as mentioned above, the portion between the two fixing parts 37 of each floss 33 is bundled together with the core yarn 20 to form a composite part 40. In this composite section 40, the multiple first long fibers contained in the core thread 20 and the multiple second long fibers contained in each embroidered floss 33 tend to intertwine to some extent, which is thought to make it difficult for each embroidered floss 33 in the chenille yarn 10a to fall off the core thread 20.
[0054] The total fineness of the chenille 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 bulky and heat-retaining fabric using the chenille yarn 10a. The total fineness of the chenille 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 relatively lightweight and highly breathable fabric using the chenille yarn 10a.
[0055] Each floss 33 may be fused and fixed to the core thread 20 at one or more portions selected from the fixing portion 37 and the composite portion 40. In this case, low-melting-point polyester fibers may be included among the plurality of first long fibers contained in the core thread 20 in a range of 10% by mass or less of the core thread 20. Also, in this case, low-melting-point polyester fibers may be included among the plurality of second long fibers contained in the floss 33 in a range of 10% by mass or less of the floss 33. Here, low melting point 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 chenille yarn 10a in which the flower floss 33 and core floss 20 are fused and fixed, the texture of the resulting fabric becomes somewhat stiff. From the viewpoint of easily producing a fabric with a soft texture, it is preferable that the chenille yarn 10a is not substantially fused and fixed to each flower floss 33 and core floss 20. For this purpose, for example, it is preferable that the plurality of first long fibers contained in the core floss 20 and the plurality of second long fibers contained in the flower floss 33 are made of polyester fibers with a melting point of 150°C or higher.
[0057] The method for manufacturing the chenille yarn 10a is not particularly limited, and those skilled in the art can manufacture it by conventional methods based on the description herein (see, for example, Patent Document 2). As an example, the chenille yarn 10a can be manufactured by the method described below. First, n core threads that have not yet been chain-knitted and (n-1) long embellishments that have not yet been cut are prepared. n is a natural number of 3 or more. The n core threads are arranged in parallel and chain-knitted, and in doing so, each long embellishment is alternately swung between the core thread to the right and the core thread to the left, overlapping the core threads as they are knitted, thereby manufacturing the chenille yarn 10a.
[0058] The above-described manufacturing method will now be explained with reference to Figures 5 and 6, illustrating an example where n=3. As shown in Figure 5, the first wale 50a, the second wale 50b, and the third wale 50c are arranged in parallel from left to right, and the chenille yarn 10a is manufactured through steps S1 to S5 described below.
[0059] In step S1, one core thread (20a, 20b, or 20c) is placed in each wale (50a, 50b, and 50c). In the leftmost first wale 50a, the core thread 20a, which has not yet been chained, is overlapped with the first long embroidery thread 31, which has not yet been cut, to form a loop 25a1 in which the core thread 20a and the first long embroidery thread 31 overlap. Similarly, in the second wale 50b, which is to the right of the first wale 50a, a loop 25b1 is formed by overlapping the core thread 20b and the second long embroidery thread 32, which has not yet been cut. Meanwhile, in the third wale 50c, which is to the right of the second wale 50b (the rightmost wale), a loop 25c1 is formed using only the core thread 20c.
[0060] In the next step S2, in the leftmost first wale 50a, the first long embroidered filament 31 is pulled out from the loop (25a1 or 25a3 described later) formed in the previous step by the core thread 20a and the first long embroidered filament 31 to the second wale 50b to the right, and the core thread 20a is passed through this loop (25a1 or 25a3 described later) to form a new loop 25a2 consisting only of the core thread 20a. In the second wale 50b, the core thread 20b formed in the "previous step" and the second long embroidered thread 32 overlap in a loop (25b1 or 25b3 described later), and only the second long embroidered thread 32 is extended to the third wale 50c to the right. The core thread 20b overlaps with the first long embroidered thread 31 extended from the first wale 50a to the left, and is passed through the loop (25b1 or 25b3 described later) formed in the "previous step," forming a new loop 25b2 in which the core thread 20b and the first long embroidered thread 31 overlap. In the third wale 50c, the core thread 20c is stretched out from the loop (25c1 or 25c3 described later) formed solely from the core thread 20c in the "previous step," overlapped with the second long embroidery thread 32 stretched out from the second wale 50b to the left, and passed through the loop (25c1 or 25c3 described later) formed in the "previous step," thereby creating a new loop 25c2 in which the core thread 20c and the second long embroidery thread 32 overlap. Note that in this step S2, "previous step" refers to the aforementioned step S1 when step S2 is being performed for the first time.
[0061] In the next step S3, in the third wale 50c on the far right, the second long embroidered filament 32 is pulled out from the loop 25c2 formed in the previous step S2, where the core thread 20c and the second long embroidered filament 32 overlap, to the second wale 50b to the left, and the core thread 20c is passed through this loop 25c2, thereby forming a new loop 25c3 consisting only of the core thread 20c. In the second wale 50b, the first long embroidered floss 31 is stretched from the loop 25b2 formed by the core thread 20b and the first long embroidered floss 31 in the previous step S2 to the first wale 50a to the left, while the core thread 20b is stretched over the second long embroidered floss 32 stretched from the third wale 50c to the right and passed through the loop 25b2 formed in the previous step S2 to create a new loop 25b3 in which the core thread 20b and the second long embroidered floss 32 overlap. In the leftmost first wale 50a, the core thread 20a is stretched out from the loop 25a2 formed in the previous step S2, overlapped with the first long embroidery thread 31 stretched out from the second wale 50b to the right, and passed through the loop 25a2 formed in the previous step S2, thereby forming a new loop 25a3 in which the core thread 20a and the first long embroidery thread 31 overlap.
[0062] Although not shown in the diagram, in the next step S4, steps S2 and S3 described above are repeated alternately multiple times. In this way, one core thread (20a, 20b, or 20c) is chain-knitted in each wale (50a, 50b, and 50c), while the first long embroidered floss 31 is bridged by alternately intertwining with the core thread 20a to its left and the core thread 20b to its right, and similarly, the second long embroidered floss 32 is bridged alternately with the core thread 20b to its left and the core thread 20c to its right. Note that when performing step S2 for the second time or later in step S4, the "previous step" in step S2 refers to the step S3 that was performed immediately before.
[0063] After going through the processes S1 to S4 described above, and weaving the core threads (20a, 20b, and 20c) with the first long embroidered thread 31 and the second long embroidered thread 32, process S5 shown in Figure 6 is performed. In this process S5, at a position 55a midway between the first wale 50a and the second wale 50b, the portion of the first long embroidered thread 31 that bridges the core threads 20a and 20b is cut. By cutting, one first long embroidered thread 31 becomes several relatively short embroidered threads 30a (flesh as multiple fragments). Similarly, at a position 55b midway between the second wale 50b and the third wale 50c, the portion of the second long embroidered thread 32 that bridges the core threads 20b and 20c is cut, forming several relatively short embroidered threads 30a (flesh as multiple fragments) from one second long embroidered thread 32. Furthermore, when the core thread 20b is pulled at both ends, the loops (25b1, 25b2, and 25b3) are tightened (contracted), and a portion of each embroidered thread 33 is gripped and secured within each tightened loop 25, thereby forming the chenille thread 10a.
[0064] Regarding step S5 described above, Figure 6 shows an example in which, after cutting the first long floss 31 and the second long floss 32, each loop (25b1, 25b2, and 25b3) is squeezed to form the chenille yarn 10a. Alternatively, from the viewpoint of making it easier to produce the chenille yarn 10a, it is preferable to form the chenille yarn 10a by squeezing each loop (25b1, 25b2, and 25b3) in step S4 or step S5 described above to grip the first long floss 31 and the second long floss 32 with the core thread 20b, and then cutting the first long floss 31 and the second long floss 32. Also, although Figures 5 and 6 describe the manufacturing method of the chenille yarn 10a when n=3, it is preferable that the more n is, the more chenille yarn 10a can be produced simultaneously. When n is 4 or more, one chenille yarn 10a can be produced for each wale, excluding the first wale on the far left and the nth wale on the far right. In other words, (n-2) strands of chenille yarn 10a can be manufactured simultaneously. Furthermore, as shown in Figure 6, the length of the distance between intermediate positions 55a and 55b (i.e., the length of the cut width L between the cutting point of the first long filament 31 and the cutting point of the second long filament 32) tends to be relatively close to twice the height T1 of each second long fiber. Also, the lower part of Figure 6 shows a micrograph of a prototype where six fixing parts 37 are formed per 0.25 inches in the direction X along the longitudinal direction of the chenille yarn 10a (24 parts / inch). In this case, the distance D between the fixing parts 37 is 1 / 24 inch.
[0065] As shown in Figures 5 and 6, in the chenille yarn 10a formed from the second wale 50b, for example, as shown in Figure 7(a), a composite section 40 is formed in which each embroidered floss 33 is bundled together with the core yarn 20 in a direction X along the longitudinal direction of the chenille yarn 10a. In Figure 7(a), each embroidered floss 33 with its tip (35a and 35b) facing upward (one side) of the paper relative to the core yarn 20 originates from the first long embroidered floss 31. In Figure 7(a), the embroidered floss 33 with its tip (35a and 35b) facing downward (the other side) of the paper relative to the core yarn 20 originates from the second long embroidered floss 32. Furthermore, as is clear from Figure 7(b), in the chenille yarn 10a, in the direction X along the longitudinal direction of the chenille yarn 10a, the embroidery floss 33 originating from the first long embroidery floss 31 and facing the upper side (one side) of the paper surface, and the embroidery floss 33 originating from the second long embroidery floss 32 and facing the lower side (the other side) of the paper surface are alternately connected. For this reason, for example, if the chenille yarn 10a is made using yarns with somewhat different physical properties for the first long embroidery floss 31 and the second long embroidery floss 32, it is possible to manufacture a chenille yarn 10a in which the characteristics such as softness and texture differ greatly between the upper side (one side) and the lower side (the other side) of the paper surface.
[0066] Although not shown in the figures, one embodiment of the fabric is a fabric containing chenille yarn 10a. For example, a woven or knitted fabric composed of chenille yarn 10a may be mentioned. The fabric may be a woven fabric composed of chenille yarn 10a interwoven with polyester fibers, or a knitted fabric composed of chenille yarn 10a interwoven with polyester fibers. From the viewpoint of incorporating a certain amount of chenille yarn 10a into the fabric to easily exhibit the heat retention, lightness, and breathability of the chenille yarn 10a, the content of chenille yarn 10a in the fabric may be higher than, for example, 50% by mass, and may be 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% or more, or 100%. In other words, it is even more preferable that the fabric is a woven or knitted fabric substantially composed of chenille yarn 10a. From the perspective of ease of manufacture compared to woven fabrics, it is even more preferable that the woven fabric be a knitted fabric made from chenille yarn 10a.
[0067] From the perspective of easily achieving the heat retention properties of chenille yarn 10a, a certain amount of chenille yarn 10a is used, so the weight of the fabric containing chenille yarn 10a should be, for example, 200g / m 2 The above is also acceptable, preferably 250 g / m² 2 That concludes the explanation. From the perspective of making the fabric relatively lightweight and highly breathable, the weight of the fabric containing chenille yarn 10a should be, for example, 350 g / m. 2 Preferably 300 g / m 2 The following applies: In this specification, basis weight is a measurement value obtained by the measurement method in accordance with JIS L 1096-2010, 8.3.
[0068] For applications involving the production of textile products (e.g., clothing products) that can be washed repeatedly on a daily basis, and from the viewpoint of ease of use of the fabric, the fabric containing the chenille 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 values used in this specification are obtained by the following method. (Method for measuring fiber shedding rate) Step 1: Obtain three 300mm x 300mm test pieces containing synthetic fibers from textile products such as fabrics. In this process, use a flat nichrome heater type soldering iron (Ishizaki Electric Works Co., Ltd., model number: SB-100) to cut 300mm x 300mm sections from the fabric to be used as test pieces. Step 2: Measure the mass of the obtained test specimens to the nearest 0.1 μg using an electronic balance. Wash each test specimen individually in a drum-type washing machine without detergent, in accordance with the JIS L 1930 C4M method. Dry the washed test specimens by tumble drying in the same drum-type washing machine. Step 3: Measure the mass of the dried test specimen to the nearest 0.1 μg using an electronic balance. Let L0 be the mass measurement of the test specimen before washing, and L1 be the mass measurement of the test specimen after washing and drying. Calculate the percentage of fiber (microplastic) shedding from the test specimen using the following formula. Dropout rate (%)=((L0-L1) / L0)×100
[0070] From the viewpoint of easily producing textile products (e.g., clothing products) that are quick-drying and less prone to stuffiness, it is preferable that the time it takes for the diffusible residual moisture content of a fabric containing chenille 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 at 20°C × 65% RH, measuring the mass at each time, and using the following formula. Residual moisture content (%) = Moisture content at each time point (g) / Moisture content immediately after dropping (back side) (g) × 100
[0071] From the viewpoint of easily producing textile products (e.g., clothing products) that are highly breathable and less prone to stuffiness, the air permeability of a fabric containing chenille yarn 10a is preferably 100 cc / cm². 2 (seconds) or more, more preferably 150 cc / cm³ per second. 2 It is (in seconds) or more. In this specification, the air permeability is a measured value in accordance with JIS L 1096-2010, Method 8.26.1 A (Fragile method).
[0072] From the viewpoint of easily producing textile products (e.g., clothing products) with excellent heat retention properties, the heat retention rate of a fabric containing chenille yarn 10a is preferably 60% or more, and more preferably 65% or more. The heat retention rate values in this specification are values obtained by the measurement method in accordance with JIS L 1096 8.27.
[0073] Although not shown in the figures, one embodiment of the garment product is a garment comprising a fabric containing chenille yarn 10a. Examples include tops, trousers, skirts, outerwear, underwear, pajamas, hats, gloves, or socks. From the viewpoint of taking advantage of the characteristic of chenille yarn 10a that the embroidery floss 33 does not easily fall out from the core yarn 20, the garment product comprising a fabric containing chenille yarn 10a is preferably an ordinary garment that is washed repeatedly on a daily basis. Furthermore, from the viewpoint of taking advantage of the heat retention, lightness, and breathability of chenille yarn 10a, it is even more preferable that the garment product comprising a fabric containing chenille yarn 10a is a garment that replaces conventional fleece garments. If it is a garment that replaces fleece garments, the mass of the garment product is preferably 200g or more and 450g or less.
[0074] <Other Embodiments 2 to 8> The following describes chenille yarns (10b to 10g) according to other embodiments, with reference to Figures 8 to 13. Each of these chenille yarns (10b to 10g) has a structure and effect that is generally similar to the chenille yarn 10a (Figure 7(a)) described above. The explanation of matters common to chenille yarn 10a will be generally omitted, and the differences will be explained mainly.
[0075] The chenille yarn 10b according to Embodiment 2 shown in Figure 8(a) includes a single chain-knitted core yarn 20 and a plurality of embellishment flosses 30b held by the core yarn 20. Each embellishment floss 33 included in the plurality of embellishment flosses 30b has two fixing portions 37 that are sandwiched within a loop 25 formed and tightened on the core yarn 20. The chenille yarn 10b can be manufactured, for example, in the third wale (nth wale) in the manufacturing method described using Figures 5 and 6 (when n=3). That is, each embellishment floss 33 in the chenille yarn 10b may originate from a second long embellishment floss 32, with both the first tip 35a and the second tip 35b facing the upper side (one side) of the paper in Figure 8(a). On the other hand, the chenille yarn 10b does not include any embellishment floss with its tip facing the lower side (the other side) of the paper in Figure 8(a). Figure 8(b) shows multiple embroidered flosses 30b in the chenille yarn 10b with the core thread 20 removed, in order to explain the positional relationship of each embroidered floss 33 in the chenille yarn 10b (the relationship between (a) and (b) in Figure 8 is the same as the relationship between (a) and (b) in Figures 9 to 13 described later). As is clear from Figures 8(a) and 8(b), in the direction X along the longitudinal direction of the chenille yarn 10b, composite sections 40 in which the core thread 20 and each embroidered floss 33 are bundled together, and sections consisting only of the core thread 20, are alternately repeated. The chenille yarn 10b has a bulky appearance on the upper side (one side) of the paper due to the embroidered flosses 33, but is lighter on the lower side (the other side) of the paper because there are no embroidered flosses.
[0076] The chenille yarn 10c according to Embodiment 3 shown in Figure 9(a) includes a single chain-knitted core yarn 20 and a plurality of embellishment yarns 30c held by the core yarn 20. Each embellishment yarn 33 included in the plurality of embellishment yarns 30c has two fixing parts 37 that are sandwiched within a loop 25 formed and tightened on the core yarn 20. Compared to the chenille yarn 10b described above (Figures 8(a) and 8(b)), the chenille yarn 10c (Figures 9(a) and 9(b)) is constructed in a generally similar 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 chenille yarn 10c has a bulky appearance due to the embellishment yarns 33 on both the upper side (one side) and the lower side (the other side) of the paper, and is lighter than the chenille yarn 10a described above (Figures 7(a) and 7(b)) because it has less embellishment yarn 33.
[0077] The chenille yarn 10d according to Embodiment 4 shown in Figure 10(a) includes a single chain-knitted core yarn 20 and a plurality of embellishment yarns 30d held by the core yarn 20. Each embellishment yarn 33 included in the plurality of embellishment yarns 30d has two fixing parts 37 that are sandwiched within a loop 25 formed and tightened on the core yarn 20. In each embellishment yarn 33 of the chenille yarn 10d, as shown in Figure 10(b), the first tip 35a faces the upper side (one side) of the paper and the second tip 35b faces the lower side (the other end). Compared with the chenille yarn 10a described above (Figures 7(a) and 7(b)), the chenille yarn 10d tends to have nearly uniform characteristics such as softness and texture between the upper side (one side) and the lower side (the other side) of the paper, even if, for example, the physical properties of the first long embellishment yarn and the second embellishment yarn used in the manufacturing process are different.
[0078] The chenille yarn 10e according to Embodiment 5 shown in Figure 11(a) includes a single chain-knitted core yarn 20 and a plurality of embellishment yarns 30e held by the core yarn 20. Each embellishment yarn 33 included in the plurality of embellishment yarns 30e has three fixing portions 37 formed by passing through three of the loops of a plurality of loops formed and tightened on the core yarn (Figure 11(b)), with both the first tip 35a and the second tip 35b facing upward (one side) of the paper. In the direction X along the longitudinal direction of the chenille yarn 10e, a composite portion 40 in which each embellishment yarn 33 is bundled together with the core yarn 20 and a portion consisting only of the core yarn 20 are alternately repeated. In the chenille yarn 10e, each flower floss 33 has three fixing parts 37, which is preferable from the viewpoint that the flower floss 33 is less likely to fall off the core yarn 20 compared to the case where each flower floss 33 has two fixing parts, as in the chenille yarn 10b (Figures 8(a) and 8(b)) described above.
[0079] The chenille yarn 10f according to Embodiment 6 shown in Figure 12(a) includes a single chain-knitted core yarn 20 and a plurality of embellishment yarns 30f held by the core yarn 20. Each embellishment yarn 33 included in the plurality of embellishment yarns 30f has three fixing parts 37 formed thereon (Figure 12(b)). Each embellishment yarn 33 in the chenille yarn 10f has its first tip 35a facing the upper side (one side) of the paper and its second tip 35b facing the lower side (the other side) of the paper. Except for this point, the chenille yarn 10f is constructed in the same way as the chenille yarn 10e described above (Figure 12(a)).
[0080] The chenille yarn 10g according to Embodiment 7 shown in Figure 13(a) includes a single chain-knitted core yarn 20 and a plurality of embellishing yarns 30f held by the core yarn 20. Each embellishing yarn 33 included in the plurality of embellishing yarns 30f has three fixing portions 37 formed thereon (Figure 13(b)). In the direction X along the longitudinal direction of the chenille yarn 10g, composite portions 40 in which each embellishing yarn 33 is bundled together with the core yarn 20 are repeatedly connected, and except for this point, the chenille yarn 10g is constructed in the same way as the chenille yarn 10e described above (Figure 11(a)).
[0081] In the chenille yarn according to the present invention, it is desirable that each flower floss has two or more fixing parts, more preferably three or more, to prevent the flower floss from falling off the core thread. From the viewpoint of avoiding complexity in the manufacturing process, the chenille yarn according to the present invention may have five or fewer fixing parts, or four or fewer, to be formed on each flower floss.

[0083] The present invention is not limited to the embodiments described above, and can be implemented in various forms with improvements, modifications, or alterations based on the knowledge of those skilled in the art, without departing from the spirit of the invention. The present invention can also be implemented in a form in which any specific item is replaced with another technology, as long as the same function or effect is produced. [Examples]
[0084] Several examples are described below, but the present invention is not limited to these examples.
[0085] Core yarn: False-twist crimped yarn A1 Using polyethylene terephthalate (0.3% by mass of matting agent, semi-dull (SD)), the yarn was melt-spun at 280°C using a conventional spinning machine, taken up at a speed of 2,800 m / min, and wound without stretching to obtain a semi-stretched multifilament yarn. This multifilament yarn contained 36 PET filaments, and the cross-sectional shape of each filament was circular. This multifilament yarn was subjected to simultaneous stretching and false-twist crimping under the conditions of a stretching ratio of 1.6 times, false twist count of 2,500 T / m (S direction), heater temperature of 180°C, and yarn speed of 350 m / min to produce a false-twist crimped yarn A1 (PET SD84T36, crimping rate 20%) with a total fineness of 84 dtex / 36 fibers. The single fiber fineness of the PET filaments contained in this yarn A1 is approximately 2.3 dtex.
[0086] Core yarn: False-twist crimped yarn A2 Using polyethylene terephthalate (containing 0.3% by mass of a matting agent), the yarn was melt-spun at 280°C using a conventional spinning apparatus, taken up at a speed of 2,800 m / min, wound without stretching, and semi-stretched multifilament yarn was obtained. From this multifilament yarn, we produced a false-twist crimped yarn with torque in the S direction and a false-twist crimped yarn with torque in the Z direction. Specifically, under the conditions of a draw ratio of 1.6 times, a false twist count of 2,500 T / m (S direction or Z direction), a heater temperature of 180°C, and a yarn speed of 350 m / min, we performed drawing and false-twist crimping simultaneously to obtain two types of false-twist crimped yarns with different torque directions. Next, a false-twist crimped yarn with torque in the S direction and a false-twist crimped yarn with torque in the Z direction were joined together and subjected to air entanglement treatment. This air entanglement treatment was an interlacing process using an interlacing nozzle, with an overfeed rate of 1.0% and a compressed air pressure of 0.3 MPa (3 kgf / cm²). 2 A false-twist crimped yarn A2 (PET SD66T72, crimp rate 28%) was fabricated as a composite yarn by applying 50 entanglements / m. This yarn A2 has a total fineness of 66 dtex / 72 strands and a torque of 0 T / m, and the single fiber fineness of the PET filament contained in yarn A2 is approximately 0.92 dtex.
[0087] Core yarns used for comparison: Non-crimped yarns A3, A4 As non-crimped yarn A3, a multifilament yarn (NY6 56T / 17) made of nylon 6 with a total fineness of 56 dtex / 17 strands was prepared. Additionally, as non-crimped yarn A4, a multifilament yarn (NY6 78T / 24) made of nylon 6 with a total fineness of 78 dtex / 24 strands was prepared. These yarns A3 and A4 were substantially free of crimp, and the single-fiber fineness of the included NY6 filaments was approximately 3.3 dtex.
[0088] Flower yarn: False-twisted crimped yarn B1: Compared to false-twist crimped yarn A1, false-twist crimped yarn B1 (PET CD84T72, crimping rate 8%) was produced under similar trial conditions, except that cationic dyeable copolymer 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 total fineness of the PET long fibers contained in yarn B1 is approximately 1.2 dtex.
[0089] Flower yarn: False-twisted crimped yarn B2 Using polyethylene terephthalate (containing 0.3% by mass of a matting agent, full-dull (FD)), the yarn was melt-spun at 280°C using a conventional spinning machine, 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 a cross-shaped cross-section for its single fibers. This multifilament yarn was subjected to simultaneous stretching and crimping using a two-heater false twist crimping method with a false twist count of 2,633 T / m, heater temperatures (first heater 160°C, second heater 170°C), and yarn speed of 140 m / min to produce a false twist crimped yarn B2 (PET FD84T72, crimping rate 9.4%) with a total fineness of 84 dtex / 72 strands. Each PET long fiber contained in yarn B2 has a single fiber fineness of 1.2 dtex and a cross-shaped cross-section.
[0090] Flower yarn: False-twisted crimped yarn B3 Using polyethylene terephthalate (containing 0.3% by mass of a matting agent, full-dull (FD)), the yarn was melt-spun at 280°C using a conventional spinning machine, taken up at a speed of 2,800 m / min, wound without stretching, and obtained a semi-stretched multifilament yarn. This multifilament yarn has a flattened cross-sectional shape for its single fibers. This multifilament yarn was subjected to simultaneous stretching and crimping using a two-heater false twist crimping method with a false twist count of 2,633 T / m, heater temperatures (first heater 160°C, second heater 170°C), and yarn speed of 140 m / min, to produce a false twist crimped yarn B3 (PET FD84T30, crimping rate 2.5%) with a total fineness of 84 dtex / 30 strands. Each PET long fiber contained in this yarn B5 has a single fiber fineness of 2.8 dtex and a flattened cross-section.
[0091] Comparing flosses: Uncurled yarns B4 and B5 As non-crimped yarn B4, a commercially available multifilament yarn made of rayon with a total fineness of 84 dtex / 50 strands (rayon 84T / 50) was prepared. The single fiber fineness of the rayon filaments contained in yarn B4 is approximately 1.7 dtex. In addition, as non-crimped yarn B5, a commercially available multifilament yarn made of rayon with a total fineness of 84 dtex / 24 strands (rayon 84T / 24) was prepared. The single fiber fineness of the rayon filaments contained in yarn B5 is 3.5 dtex. The rayon filaments contained in yarns B4 and B5 respectively had virtually no crimp.
[0092] As shown in Table 1, in combinations where one of the aforementioned yarns A1 to A4 is used as the core yarn and one of the aforementioned yarns B1 to B5 is used as the embellishing yarn (Each of Examples 1 to 9, and Comparative Examples 10 and 11), the chenille yarn produced in each wale was adopted as the chenille yarn for the example or comparative example, after going through steps S1 to S5 in the aforementioned chenille yarn manufacturing method when n=4 or more, excluding the wale at the far right and the wale at the far left. In other words, each of the prototyped chenille yarns is a chenille yarn containing one chain-knitted core yarn and multiple embellishing yarns held by this core yarn. In this prototype, no heat fusion was performed between the core yarn and the embellishing yarns. Microscopic images of the chenille yarns for Examples 4 to 9, and Comparative Examples 10 and 11 are shown in Figure 14. For each prototyped chenille yarn, the single fiber fineness of each long fiber contained in the core yarn and embellishing yarn, and the ratio (height T1 / height T2) of each long fiber contained in the embellishing yarn measured by the method described above are shown in Table 1.
[0093] [Table 1]
[0094] For each of the prototyped chenille yarns from Examples 1 to 9 and Comparative Examples 10 and 11, the height T1, height T2, and radius of curvature of each long fiber contained in the embroidery floss were measured, and the spacing between the fixing points of the embroidery floss in the core yarn was also measured, as shown in Table 2.
[0095] [Table 2]
[0096] For each of Examples 1 to 9 and Comparative Examples 10 and 11, a mesh knit fabric having the structure shown in Figures 15(a) and 15(b) was fabricated using only the prototyped chenille yarn as the material, by conventional methods. For each prototyped knit fabric (a woven fabric consisting only of chenille yarn), the basis weight, fiber shedding rate, air permeability, and heat retention rate were measured using the measurement method described above, and are shown in Table 3.
[0097] [Table 3]
[0098] Tables 1 to 3 suggest that, compared to Comparative Examples 10 and 11, Examples 1 to 9 showed higher heat retention and significantly lower fiber shedding rates in the fabrics. Compared to Comparative Example 10, Examples 1 to 9 showed relatively lower basis weight (relatively lighter) and higher breathability.
[0099] Furthermore, for each of Examples 1 to 9 and Comparative Examples 10 and 11, a seamless shirt (whole garment) for adult men was prototyped using only the prototyped chenille yarn as material, and by conventional methods, 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 prototyped shirts were lightweight, with a mass in the range of 200g to 450g. When the shirts prototyped from the chenille yarn of Comparative Example 10 or 11 were tried on outdoors in winter, they felt as warm as commercially available shirts made of conventional fleece material. On the other hand, when the shirts prototyped from the chenille yarn of Examples 1 to 5 and the shirts prototyped from the chenille yarn of Examples 7 to 9 were tried on outdoors in winter, they felt even warmer than commercially available shirts made of conventional fleece material.
