DETAILED DESCRIPTION OF THE INVENTION

[0011] The fabric constituting the water-absorbing and dispersive fabric of the present invention is a knitted or woven fabric containing a core component made of synthetic multifilament yarn and a sheath component made of animal hair fibers or a blend of animal hair fibers and short fibers other than animal hair fibers. This fabric has been subjected to a water-absorbing and dispersing treatment in which a water-absorbing and dispersing agent is adsorbed. Therefore, when liquid water (e.g., the main component of sweat) adheres to the fabric, the water quickly penetrates from the sheath component fibers on the surface of the fabric into the synthetic multifilament core component yarn within the fabric, where it is absorbed and diffused in the plane of the fabric. This water-absorbing and dispersing treatment imparts water-absorbing and dispersing properties to the synthetic multifilament core component yarn. Liquid water that collects in one place is difficult to dry, becomes damp, and the fabric sticks to the skin, making it difficult to release, resulting in a poor wearing comfort. However, in the water-absorbent and water-diffusing fabric of the present invention, when liquid water adheres to the fabric, the water quickly penetrates into the yarns, preventing stickiness on the surface of the fabric, and the water quickly diffuses in the planar direction of the fabric, allowing the fabric to dry easily and providing a good feel and texture. Furthermore, by including animal hair fibers in the sheath component, the part that comes into contact with the skin has a good texture.

[0012] The water-absorbing / diffusing agent for the fabric may be any hydrophilic substance that can adhere to fibers and impart affinity to moisture, and those commonly used in the textile field can be used. Examples of water-absorbing / diffusing agents include water-absorbent polyester resins, water-absorbent silicone resins, water-absorbent acrylic resins, and water-absorbent nylon resins, each of which is block copolymerized with a hydrophilic component, such as polyester resin, silicone resin, acrylic resin, or nylon resin, as well as nonionic polymer surfactants. When the water-absorbing / diffusing agent is adsorbed into the synthetic multifilament yarn, which is the core component, water easily penetrates into the interior of the synthetic multifilament yarn and diffuses in the planar direction of the fabric. More specifically, water easily penetrates between the filaments that make up the synthetic multifilament yarn, and the water that has entered between the filaments easily diffuses in the planar direction of the fabric. This enhances the effect of suppressing stickiness.

[0013] These water-absorbing and diffusing agents may be used alone or in combination of two or more. More specifically, examples include polyethylene oxide-added polyester compounds (e.g., block copolymers of polyethylene glycol and polyethylene terephthalate) and polyethylene oxide-added silicone compounds. Commercially available water-absorbing and diffusing agents include, for example, "Parasolve PET" manufactured by Ohara Palladium Chemical Co., Ltd. and "SR1801" manufactured by Takamatsu Oil & Fat Co., Ltd. When the core component is a polyester multifilament yarn, the water-absorbing and diffusing agent is preferably a water-absorbent polyester resin. Because water-absorbent polyester resins have a high affinity with the polyester multifilament core component, the water-absorbing and diffusing properties of the polyester multifilament yarn are significantly improved.

[0014] The long-short composite spun yarn is preferably a ring-spun yarn or a tying-spun yarn. Ring-spun yarns can be produced using a ring spinning machine, and tying-spun yarns can be produced using a tying-spinning machine. The long-short composite spun yarn produced using the tying-spinning machine is composed of a core component and a sheath component, and the sheath component includes an inner layer fiber and a surface layer fiber arranged outside the core component, in that order from the core component side. Therefore, the long-short composite spun yarn has a three-layer structure. Because this yarn structure is strong, using a tying-spun yarn as the long-short composite spun yarn can improve the friction strength and anti-pilling properties of the fabric.

[0015] The synthetic multifilament yarn is preferably a polyester multifilament yarn or a nylon multifilament yarn. In particular, the synthetic multifilament yarn is preferably a polyester multifilament yarn. Polyester multifilament yarn is composed of hydrophobic fibers with a low standard moisture regain of approximately 0.4%, and while moisture easily penetrates between the polyester filaments that make up the yarn, it is hardly absorbed into the filaments (fibers). Therefore, when the polyester multifilament yarn is given moisture absorption and diffusion properties by the moisture absorption and diffusion treatment, it is preferred because it absorbs and diffuses moisture faster into the yarn and dries faster than synthetic multifilament yarn composed of more hydrophilic filaments.

[0016] The synthetic fiber multifilament yarn is preferably at least one selected from the group consisting of raw silk (raw silk), conjugate multifilament yarn, and false-twisted multifilament yarn. Among these, false-twisted multifilament yarn is preferred because it is stretchable, does not easily protrude outside the sheath component, and is less likely to cause snarnling.

[0017] When the long and short composite spun yarn is taken as 100% by mass, the blending ratio of animal hair fibers is preferably 5 to 90% by mass, more preferably 7 to 85% by mass, and even more preferably 10 to 80% by mass. This allows the excellent texture of animal hair fibers to be exhibited. Examples of animal hair fibers that can be used include sheep's wool (merino wool, fiber length 30 to 150 mm), goat's mohair (fiber length 100 to 300 mm), cashmere (fiber length 40 to 90 mm), camel's camel hair (fiber length 50 to 70 mm), alpaca (fiber length 100 to 200 mm), vicuña (fiber length 20 to 70 mm), and rabbit's Angora rabbit (fiber length 100 to 130 mm). Of these, wool is preferred as it is the most versatile. Wool may also be blended with other animal hair fibers. In the case of ring spun yarn, the animal hair fibers are preferably spun at their original length (long spinning), while in the case of bundle spun yarn, the animal hair fibers are preferably cut to an average fiber length of 20 to 35 mm before being spun (short spinning).

[0018] The sheath component may be a blend of animal hair fibers and staple fibers other than animal hair fibers. The staple fibers other than animal hair fibers may be synthetic fibers, regenerated fibers, or natural fibers. Preferred staple fibers other than animal hair fibers include polyester staple fibers, nylon staple fibers, cellulose acetate staple fibers, cupra staple fibers, silk staple fibers, cotton fibers, hemp fibers, and rayon fibers. From the viewpoint of improving the water absorption and diffusibility of the long-short composite spun yarn, the staple fibers other than animal hair fibers are preferably more hydrophobic than animal hair fibers. When the staple fibers other than animal hair fibers are hydrophobic fibers such as polyester staple fibers, the water absorption and diffusibility of the polyester staple fibers is improved by the water absorption and diffusibility treatment described above. However, since the water is hardly absorbed into the polyester staple fibers, drying is also fast, which is preferable. Polyester staple fibers are also preferable because they have high strength and stiffness. In the case of bundle spinning, the staple fibers other than animal hair fibers are preferably cut to an average fiber length of 20 to 51 mm. In the case of ring-spun yarn, the short fibers other than animal hair fibers are preferably cut to an average fiber length of 70 to 90 mm.

[0019] When the long and short composite spun yarn is taken as 100% by mass, preferably the synthetic fiber multifilament yarn serving as the core component is 10 to 40% by mass and the sheath component is 60 to 90% by mass, more preferably the synthetic fiber multifilament yarn serving as the core component is 15 to 35% by mass and the sheath component is 65 to 85% by mass, and even more preferably the synthetic fiber multifilament yarn serving as the core component is 20 to 30% by mass and the sheath component is 70 to 80% by mass.

[0020] The long and short composite spun yarn in the present invention is preferably a typographical spun yarn because of its excellent productivity. Compared to ring-spun yarn, typographical spun yarn is approximately 10 to 20 times more productive. In particular, typographical spun yarn obtained by a typographical spun device with a single swirl flow nozzle has less fuzz and a stronger yarn structure, which can improve the friction strength and anti-pilling properties of the fabric. Note that typographical spun yarn is also called vortex spinning.

[0021] The thickness of the long and short composite spun yarn is preferably in the range of 20 to 80 metric count (single yarn) (fineness: 500 to 125 decitex). Within this range, the moisture-absorbing and dispersive fabric is suitable for T-shirts, sports shirts, underwear, inner pants, tights, socks, business suits, business uniforms, school uniforms, etc. When the moisture-absorbing and dispersive fabric is a knitted fabric, the long and short composite spun yarn is preferably a single yarn. When the moisture-absorbing and dispersive fabric is a woven fabric, the long and short composite spun yarn is preferably a two-ply yarn formed by twisting two single yarns together. The two-ply yarn preferably has a metric count of 10 to 40 (fineness: 1000 to 250 decitex). When the long and short composite spun yarn is a two-ply yarn, the surface of the fabric becomes smooth and the strength of the woven fabric increases.

[0022] The mass per unit area of ​​the moisture-wicking fabric of the present invention is 200 g / m 2 Preferably, the density is 50 to 200 g / m or less, more preferably 50 to 200 g / m 2 and more preferably 50 to 180 g / m 2 Within the above range, the garment can be lighter and more comfortable to wear. The woven fabric may be of any type, such as plain weave, twill weave, satin weave, or other variegated weaves. The knitted fabric may be of any type, such as flat knitting, circular knitting, or warp knitting.

[0023] The water absorption length of the core filament constituting the long-short composite spun yarn is preferably 1.2 to 3 times, more preferably 1.2 to 2.5 times, the water absorption length of the long-short composite spun yarn. This increases the water diffusibility of the core filament, suppresses stickiness on the fabric surface, and makes the fabric easier to dry. The water absorption lengths of the core filament and the long-short composite spun yarn can be measured by the method described in the Examples.

[0024] The method for producing a water-absorbing and dispersing fabric of the present invention includes dyeing a fabric containing the long and short composite spun yarn, and then contacting the fabric with a water-absorbing and dispersing agent at a temperature lower than the dyeing temperature, thereby causing the absorbent and dispersing agent to adsorb onto the dyed fabric. For example, in one embodiment, the method for producing a water-absorbent / diffusive fabric of the present invention includes dyeing the fabric with a heated dye liquor and then performing an adsorption treatment using an aqueous dispersion of the water-absorbent / diffusive agent to adsorb the water-absorbent / diffusive agent onto the fabric. The aqueous dispersion of the water-absorbent / diffusive agent is placed in a dyeing tank from which the dye liquor has been discharged, and the dyed fabric is immersed in the heated aqueous dispersion of the water-absorbent / diffusive agent. Alternatively, the method for producing a water-absorbent / diffusive fabric of the present invention can also employ a padding method. Specifically, for example, the dyed fabric is immersed in an aqueous dispersion of the water-absorbent / diffusive agent at room temperature to allow the fabric to absorb the aqueous dispersion, and then the fabric is squeezed with a mangle to uniformly penetrate the water-absorbent / diffusive agent, followed by drying (heat treatment). Depending on the type of resin, the resin may be fixed by a heat setting process at a higher temperature after drying.

[0025] Suitable garments comprising the moisture-absorbing and diffusive fabric of the present invention include T-shirts, sports shirts, underwear, inner pants, tights, socks, business suits, business uniforms, school uniforms, and the like.

[0026] Next, an apparatus and method for producing the sheath-core yarn used in the production of the moisture-absorbing and diffusive fabric of the present invention will be described with reference to the drawings. In the following drawings, the same reference numerals indicate the same parts.

[0027] FIG. 1 is a schematic cross-sectional view showing the diffusion of liquid water when it adheres to a woven or knitted fabric according to one embodiment of the present invention. When liquid water 54 (e.g., moisture contained in sweat) adheres to fabric 51, water 54 enters the synthetic multifilament yarn of core component 52 from the sheath component fibers on the surface of fabric 51 and is absorbed and diffused along arrows 56a and 56b. This is because the above-described water absorption and diffusion treatment imparts water absorption and diffusion properties to the synthetic multifilament yarn of core component 52. If liquid water 54 collects in one place, it is difficult to dry, feels damp, sticks to the skin, and has poor skin release properties, resulting in a poor wearing comfort. However, if liquid water 54 diffuses quickly, it dries easily, resulting in good skin release properties and a good texture. Furthermore, sheath components 53a and 53b contain animal hair fibers, resulting in a good texture.

[0028] FIG. 2 is a perspective view showing the main part of the bundle spinning device 1 according to one embodiment of the present invention. (1) Drafting process The draft zone 6 of the bundle spinning device 1 is composed of a pair of front rollers 2, 2′, a pair of second rollers 3 with aprons, a pair of third rollers 4, and a pair of back rollers 5. A sliver 7, which serves as the sheath component and is made by blending, for example, animal hair fibers with short fibers other than animal hair fibers, passes through a sliver guide 8, is supplied from the back rollers 5, and is drafted in the draft zone 6. (2) Combining the core and sheath components A synthetic multifilament yarn 9 serving as a core component is supplied to the draft zone 6 in front of the front rollers 2, 2' (upstream side), and the sliver 7 is combined with the drafted fiber bundle. (3) Spun yarn formation process The combined fiber bundles for the core component and sheath component are fed to a spindle 10 arranged away from the discharge portion of the front rollers 2, 2', and false twisted by a swirling flow to form a long and short composite spun yarn 11. (4) Winding process The obtained long and short composite spun yarn 11 passes through a slub catcher 12, is taken up by a friction roller 13, and is driven by a winding drum 14 of a winding section 17 and wound onto a package 16 supported by a cradle arm 15. The spinning machine used in the manufacturing method of the present invention is, for example, manufactured by Murata Machinery Co., Ltd. and sold under the trade name "MURATA VORTEX SPINNER." A distinctive feature of this machine is that it has a yarn speed of 300 to 450 m / min, which is about 10 to 20 times faster than a ring spinning machine.

[0029] FIG. 3 shows a long-short composite spun yarn (bundled spun yarn) 20 according to an example of the present invention. In this example, the blend ratio of animal hair fibers such as wool is 15% by mass when the long-short composite spun yarn is 100% by mass. The core component 21 is a synthetic multifilament yarn, and the sheath component 24 is a blend of animal hair fibers such as wool and staple fibers other than animal hair fibers, such as polyester (PET) staple fibers. The animal hair fibers such as wool are present in large amounts in the inner layer and are in an untwisted state. The staple fibers other than animal hair fibers, such as PET staple fibers, are present in large amounts in the surface layer and are wound around the inner layer fibers 22 to form the surface layer. The wound fibers in the surface layer (surface layer fibers 23) are twisted and form a true twist, binding the entire yarn together. As a result, the long-short composite spun yarn has little fuzz or slack, does not lose fibers even when worn, and maintains a strong yarn state. In the above, "unidirectional" refers to the winding direction of the S twist or the winding direction of the Z twist, and does not mean that the twist angle is the same. The winding direction of the S twist or the Z twist is determined by the direction of the compressed air swirl flow of the spinner of the tying spinning machine. This long-short composite spun yarn (tying spun yarn) 20 has a three-layer structure consisting of a core component 21, an inner layer fiber 22 of a sheath component 24, and a surface layer fiber 23. This yarn structure results in high yarn strength. Furthermore, the animal hair fiber such as wool that constitutes the inner layer fiber 22 is covered and protected by the short fiber other than animal hair fiber such as PET short fiber that constitutes the surface layer fiber 23, thereby preventing damage to the wool.

[0030] Another example of a long-short composite spun yarn (bundled spun yarn) 25 according to the present invention is shown in Figure 4. In this example, the blend ratio of animal hair fibers such as wool is 35% by mass when the long-short composite spun yarn 25 is taken as 100% by mass. The difference from Figure 3 is that both the inner layer fiber 26 of the sheath component 28 and the surface layer fiber 27 wrapped around the inner layer fiber 26 are blended fibers of animal hair fibers such as wool and staple fibers other than animal hair fibers such as PET staple fibers. 26b denotes animal hair fibers such as wool that form the inner layer, and 26a denotes staple fibers other than animal hair fibers such as PET staple fibers that form the inner layer. 27b denotes animal hair fibers such as wool that form the surface layer, and 27a denotes staple fibers other than animal hair fibers such as PET staple fibers that form the surface layer. This long-short composite spun yarn also has a three-layer structure, resulting in high yarn strength. In addition, in the surface layer, animal hair fibers such as wool and short fibers other than animal hair fibers such as PET short fibers are tightly entangled, so damage to the animal hair fibers such as wool is prevented.

[0031] Figure 5 is a perspective view showing the main parts of a ring spinning frame 30 for producing long and short composite spun yarns. A front bottom roller 34 is provided for each spindle on a front bottom main shaft 33 that is driven to rotate in a positive direction. A front top roller 35 is placed on top of the front bottom roller 34. The front top rollers 35 are covered with a rubber cot and fitted onto a common arbor 36 to be able to roll independently. A short fiber bundle (roving) 45 drawn from a roving bobbin 31 is supplied to a back roller 38 via a guide bar and a trumpet feeder 37. The short fiber bundle delivered from the back roller 38 and drafted by a draft apron 39 is nipped by the front bottom roller 34 and front top roller 35 and spun.

[0032] Meanwhile, multifilament yarn 46 is unwound from pirn 32 while being rotated in the direction of arrow 48, passes through nip rollers (supply rollers) 49, passes through yarn guide 44 with 0.5 to 5% overfeed, and is supplied to the upstream side of front top roller 35. It is overlapped with the staple fiber bundle at the nip line between front bottom roller 34 and front top roller 35, and then a real twist is added. The real twist is added by passing the yarn through snell wire 40 and antinode ring 41, and winding it onto a spindle-mounted yarn spool 43 via traveler 42. The resulting long and short composite spun yarn 50 is wound onto yarn spool 43.

[0033] FIG. 6 shows a long-short composite spun yarn (ring-spun yarn) 50 according to one example of the present invention. In the long-short composite spun yarn 50, a multifilament yarn serving as a core component 57 and a staple fiber bundle serving as a sheath component 58 are twisted together. When viewed from a cross section, the synthetic fibers constituting the multifilament yarn are present in a cluster, with some exposed but most contained within the sheath component 58 and concentrated in clusters around the periphery. In other words, the multifilament yarn serving as the core component 57 is eccentric in the long-short composite spun yarn 50. When viewed from the side, the multifilament yarn serving as the core component 57 is twisted spirally along the twist direction of the long-short composite spun yarn. Because the multifilament yarn serving as the core component 57 is mostly surrounded by the sheath component 58, the multifilament yarn is buried and less exposed, allowing the properties of the sheath component 58 to be fully utilized. This results in the long-short composite spun yarn 50 having a soft, fluffy texture with less crispness. [Example]

[0034] The present invention will be explained in more detail below using examples, but the present invention is not limited to the following examples. Measurement methods other than those listed below were performed in accordance with JIS or industry standards.

[0035] <Water absorption of spun yarn (water absorption length)> The yarn was removed from the knitted fabric, and the water absorbency of the long-short composite spun yarn was measured in accordance with the Byreck method specified in JIS L 1907: 2010. Specifically, a 10 g load was applied to 20 cm of the yarn removed from the knitted fabric, and the yarn was immersed 20 mm into a water tank. After 10 minutes of immersion, the height (mm) of water that rose above the water surface due to capillary action was measured.

[0036] <Water absorption of the core part (water absorption length)> The yarn removed from the knitted fabric was squeezed to remove the sheath, and only the core (synthetic multifilament yarn) was extracted. Ten of the extracted synthetic multifilament yarns were bundled together, and the water absorption of the core was measured. Specifically, a 10 g load was applied to a bundle of ten 20 cm synthetic multifilament yarns, which were then immersed 20 mm into a water tank. 10 minutes after immersion, the height (mm) of water rising above the water surface due to capillary action was measured.

[0037] <Water absorption of knitted fabric> The water absorbency was measured by the dropping method specified in JIS L 1907:2010. <Water absorption and diffusion properties of knitted fabric> The dropping method specified in JIS L 1907:2010 was carried out, and the diffusion area was measured 5 minutes after dropping.

[0038] <Quick-drying knit fabric> Evaluation was based on the drying time (100%) according to the method specified in ISO 17617:2014 A1.

[0039] <Stickiness of knitted fabric> A 20cm x 20cm knitted fabric was sprayed with distilled water at 50% of the weight of the knitted fabric using a spray bottle, and after 5 minutes the fabric was placed on the inside of the arm and the feel was judged. Ten subjects were tested. The evaluation criteria were as follows, and the average was used as the score. 4: It has a smooth feel without stickiness, and has excellent breathability and texture. 3: There is a slight stickiness, but the texture and feel are good. 2: Sticky feeling, and the ease of removal from the skin and texture are somewhat poor. 1: Stickiness is noticeable, and the texture and feel are very poor.

[0040] Example 1 1. Fiber used (1) Core component Nylon multifilament yarn (total fineness 33 decitex, number of filaments 12) was used as the core component. (2) Sheath component As the sheath component, Kroyharcoset shrink-proof wool with an average diameter of 19.5 μm and an average fiber length of 80 mm was used.

[0041] 2. Preparation of long and short composite spun yarn Using the ring spinning machine shown in Figure 5, a multilayered shim-spun yarn was produced using nylon multifilament yarn (Ny) as the core component and wool (W) as the sheath component. The ratio of nylon multifilament yarn (Ny) to wool (W) was 21% by mass (shown as "Ny21" in Table 1) and 79% by mass (shown as "W79" in Table 1). The metric count of the obtained long and short composite spun yarn was 60 (167 decitex). This yarn was a single yarn and was shown as 1 / 60. 3. Knitting The long and short composite spun yarn obtained above was fed to a 28-gauge circular knitting machine to knit a plain knit fabric. The mass per unit area (basis weight) of the obtained knit fabric was 150 g / m 2 It was. 4. Post-processing of knitted fabrics The knitted fabric was immersed in an acid dye solution (aqueous dispersion), heated from room temperature 25°C to 98°C, and maintained at 98°C (dyeing temperature) for 50 minutes for a dyeing process. The solution temperature was then lowered, the solution was discarded, and the dyed knitted fabric was washed with water for 10 minutes. The fabric was then immersed in an aqueous dispersion of a water-absorbing and diffusing agent containing 2% owf (on the weight of fiber) of a polyester resin-based water-absorbing and diffusing agent (manufactured by Ohara Palladium Chemical Co., Ltd., product name "Parasolve PET"), and heated from room temperature 25°C to 80°C. The temperature was then maintained at 80°C for 30 minutes for an adsorption treatment in which the water-absorbing and diffusing agent was adsorbed into the fabric. The solution temperature was then lowered, the solution was discarded, and the fabric after the adsorption treatment was washed with water for 10 minutes and dried.

[0042] Example 2 The same procedure as in Example 1 was carried out, except that polyethylene terephthalate multifilament yarn (PET) (total fineness 33 decitex, number of filaments 12) was used as the core component instead of nylon multifilament yarn (Ny).

[0043] Example 3 The same operations as in Example 2 were carried out, except that the sheath component consisted of 33 mass% polyethylene terephthalate (PET) short fibers (single fiber fineness 3.3 decitex, bias cut, average fiber length 78 mm) and 67 mass% wool (W), with the overall proportions set to the values ​​shown in Table 1. The same wool (W) as in Example 1 was used.

[0044] Example 4 The same procedure as in Example 1 was carried out using the bundling spinning machine shown in Figure 2 (manufactured by Murata Machinery Co., Ltd., product name "No. 870, MURATA VORTEX SPINNER," spinning speed 300 m / min). The core component was polyethylene terephthalate multifilament false twist textured yarn (PET) (total fineness 33 decitex, number of filaments 12). The sheath component consisted of 87 mass% polyethylene terephthalate (PET) staple fibers (single fiber fineness 1.43 decitex, square cut, average fiber length 38 mm) and 13 mass% wool (W) fibers square-cut to an average fiber length of 28 mm from fiber bundles (20 g / m) of Kroyharco shrink-proof wool with an average diameter of 19.5 μm and an average fiber length of 80 mm. The overall proportions were as shown in Table 1. The yarn structure was as shown in Figure 4.

[0045] (Comparative Examples 1 to 4) Knitted fabrics of Comparative Examples 1 to 4 were obtained in the same manner as in Examples 1 to 4, except that the dyed knitted fabric was not subjected to the treatment of adsorbing a water-absorbing and diffusing agent. The above results are summarized in Tables 1 and 2.

[0046] [Table 1]

[0047] [Table 2]

[0048] As is clear from Tables 1 and 2, in Examples 1 to 4, the moisture-absorbing and dispersing treatment of the fabric significantly improved the moisture absorption of the synthetic multifilament yarn, which is the core component of the yarn. Furthermore, the inclusion of animal hair fibers in the sheath component resulted in excellent skin-releasing properties and texture. Since Examples 1 to 4 did not have a multilayer structure like the knitted fabric of Patent Document 1, for example, they were able to produce light, thin, moisture-absorbing and dispersing fabrics. Furthermore, in Examples 1 to 4, there were no problems such as staining of the dyed product or removal of the dye, and the water-absorbing and diffusing agent was able to be reliably adsorbed onto the fabric using the aqueous dispersion of the water-absorbing and diffusing agent. [Industrial Applicability]

[0049] The water-absorbing and diffusive fabric of the present invention is suitable for use as a fabric for T-shirts, sports shirts, underwear, inner pants, tights, socks, business suits, business uniforms, school uniforms, and the like. [Explanation of symbols]
