[0002] Traditionally, towel fabrics have been basically made by weaving pile yarns, warp yarns, and weft yarns. To improve water absorption, towel fabrics have a relatively high basis weight (mass per unit area), and thick, high-fineness yarns are used as constituent yarns. Patent Documents 1 and 2 propose sizing the pile yarns and warp yarns. In Patent Documents 3 and 4, the present inventor proposes pile yarns for towel fabrics that use tying spun yarns (air-spun yarns).

[0004] However, in the case of ring-spun yarn, both the inner and outer fibers are uniformly twisted, and even if the yarn is untwisted to produce a non-twisted yarn, both the inner and outer fibers become loose, resulting in weak strength and increased fuzz. Furthermore, in the case of bundle-spun yarn (air-spun yarn), the inner fibers are usually loose and the outer fibers are tightly wound, resulting in a stiff texture.

[0005] To provide a pile yarn for towel fabric which is less likely to shed fluff, is bulky, does not easily lose its volume after washing, is less likely to get wet again, and has a comfortable wiping feel, as well as a method for producing the same and a method for producing towel fabric using the same, as a result of extensive studies to make the most of the characteristics of towel fabric.

[0011] A pile yarn for towel fabric according to one aspect of the present invention is a sheath-core spun yarn in which the core fibers are twisted in one direction and the sheath fibers are arranged parallel to the yarn axis, and the sheath-core spun yarn is plied with a water-soluble fiber yarn, and the winding direction of the water-soluble fiber yarn is opposite to the twist direction of the core fiber, thereby providing a towel fabric with a tight core fiber and a soft, fluffy texture with little fluff shedding, high bulk, resistance to loss of bulk after washing, low rewet, and a comfortable wiping feel, as well as a method for manufacturing the same.Furthermore, a towel fabric according to one aspect of the present invention is a pile woven fabric, and the pile yarn is a sheath-core spun yarn in which the core fibers are twisted in one direction and the sheath fibers are arranged parallel to the yarn axis, thereby providing a towel fabric with a tight core fiber and a soft, fluffy texture with little fluff shedding, high bulk, resistance to loss of bulk after washing, low rewet, and a comfortable wiping feel, as well as a method for manufacturing the same.

Figure 2 is a schematic side view of a pile yarn in one embodiment of the present invention. Figure 3 is a schematic explanatory diagram of a towel fabric in one embodiment of the present invention. Figure 4 is a woven structure diagram of the towel fabric in the same embodiment. Figure 5 is a side photograph (magnification 30x) of the pile portion of the towel fabric in Example 1 of the present invention before washing. Figure 6 is a side photograph (magnification 30x) of the pile portion of the towel fabric in Comparative Example 1 before washing. Figure 7 is a side photograph (magnification 30x) of the pile portion of the towel fabric in Example 1 of the present invention after 20 washes. Figure 8 is a side photograph (magnification 30x) of the pile portion of the towel fabric in Comparative Example 1 after 20 washes.

[0013] The present invention focuses on the fact that pile yarns, which account for approximately 70% of the constituent yarns of a towel fabric, are important yarns that determine the pile standing property, the towel fabric's texture, and functionality such as shedding. Through further research, the following findings were obtained: Specifically, a towel fabric according to one embodiment of the present invention includes warp yarns, weft yarns, and pile yarns, with the pile yarns anchored to the warp yarns and weft yarns. The pile yarns are sheath-core spun yarns, with the core fibers twisted in one direction and the sheath fibers oriented parallel to the yarn axis. A water-soluble fiber yarn is wrapped around the surface of the sheath-core spun yarn, and the winding direction of the water-soluble fiber yarn is opposite to the twist direction of the core fibers. This has been found to have the following advantages: (1) When the water-soluble fiber yarn is dissolved and removed in a subsequent process, the inner core fibers are tightened and the outer sheath fibers are loosened. Because the inner core fibers are tight, the strength of the towel fabric is not reduced despite the use of untwisted yarns. This results in a highly durable towel. (2) The pile yarn is a sheath-core spun yarn, with the core fibers twisted in one direction and the sheath fibers arranged parallel to the yarn axis. However, some of the core and sheath fibers undergo migration (a phenomenon in which individual fibers are twisted inward or outward), resulting in good integrity between the core and sheath fibers. This results in high strength and durability. Furthermore, because the pile yarn as a whole is either untwisted or loosely twisted, each constituent fiber exists in a free state, resulting in good pileability and a pile yarn with a soft, fluffy texture. The soft, fluffy texture provides a gentle contact with the skin and allows for efficient wiping of sweat and moisture (texture effect, wiping effect). (3) Because the pile yarn is either untwisted or loosely twisted, the constituent fibers are more likely to absorb moisture, and at the same time, this swelling promotes air movement, resulting in high breathability (water absorption effect, ventilation effect). (4) The intertwining of the constituent fibers reduces pilling (impact of reduced pilling), reduces changes in texture due to washing, and maintains the original soft and fluffy texture (effect of texture durability after washing).

[0014] The pile yarn is preferably air-spun yarn (also called shied spun yarn). Air-spun yarn has a low fuzz count, is uniform, has a strong yarn structure, is resistant to ironing, and can be used to make towel fabric without starch. Furthermore, the yarn speed (winding speed) is 300 to 500 m / min, which is approximately 10 to 30 times more productive than a ring spinning machine.

[0015] The pile yarn fineness, in terms of cotton count (S, single yarn), is preferably in the range of 10 to 50S (118 to 591 decitex). This range ensures a good texture for towel fabric. Preferred cotton for pile yarn is, for example, the extra-long staple cotton or long staple cotton shown in Table 1 below.

[0016]

[0017] The water-soluble fiber yarn is preferably a water-soluble vinylon yarn or a polylactic acid yarn. The preferred fineness is 50 to 200 in English cotton count. The preferred twist coefficient K is greater than 0 and not more than 4.0, more preferably 0.5 to 3.8, and even more preferably 1.0 to 3.5. The twist coefficient (K) is calculated using the following formula (Math 2): Where t: number of twists (twists / 25.4mm), S: total count of spun yarn and water-soluble fiber yarn (British cotton count)

[0018] The warp yarns and weft yarns of the towel fabric may be any type of yarn, such as open-end spun yarns, air-spun yarns, ring-spun yarns, long-fiber composite spun yarns, or shied spun yarns. The preferred fineness is a cotton count (S, single yarn) of 10 to 50S (118 to 591 decitex), and a twist factor K of 3.5 to 4.5. The twist factor (K) is calculated using the above formula (Equation 2). Preferred cottons for the warp yarns and weft yarns are, for example, the long-fiber cottons shown in Table 1 above.

[0019] A method for producing pile yarn for towel fabric according to one embodiment of the present invention comprises the following steps: (1) Spinning step: An air spun yarn is produced using an air spinning machine, in which the core fibers are parallel to the yarn axis and the sheath fibers are twisted in one direction. (2) Winding step: A water-soluble fiber yarn is ply-twisted onto the surface of the air spun yarn in the direction opposite to the twist direction of the core fibers. The coefficient K during plying and twisting is preferably greater than 0 and equal to or less than 4.0. A commonly used twisting machine such as a ring twisting machine is used for plying and twisting. This results in a pile yarn in which the core fibers are twisted in one direction and the sheath fibers are parallel to the yarn axis.

[0020] The towel fabric using the pile yarn according to one embodiment of the present invention is a pile woven fabric, and the pile yarn is a core-sheath spun yarn, with the core fibers twisted in one direction and the sheath fibers arranged parallel to the yarn axis. The pile woven fabric is not limited to, but an example thereof is a three-weft towel weave (3-pick terry motion weave).

[0021] In a method for manufacturing a towel fabric using the pile yarn for towel fabric according to one aspect of the present invention, after weaving the pile fabric into a pile fabric, the water-soluble fiber yarn on the surface of the pile yarn is dissolved. The dissolution of the water-soluble fiber yarn is preferably carried out during scouring, bleaching, and / or dyeing of the pile fabric.

[0022] The pile yarn is preferably 100% by mass cotton. This allows the water absorption, moisture absorption, and good texture of cotton fiber to be brought out. The pile yarn is preferably a single yarn or a two-ply yarn. The warp yarn is preferably a two-ply yarn made of 100% by mass cotton fiber. Two-ply yarns suppress pilling and allow loop pile towel fabric to be woven without starch. This warp yarn is preferably a two-ply yarn made by twisting two single yarns of ring spun yarn or tying spun yarn together. The weft yarn is preferably a single yarn made of 100% by mass cotton fiber. This weft yarn is preferably a single yarn of ring spun yarn or tying spun yarn. Furthermore, the pile yarn according to one aspect of the present invention can be a warp pile yarn or a weft pile yarn, and can be used for either, but it is preferable to use it as a warp pile yarn.

[0023] The mass per unit area (basis weight) of the towel fabric according to one embodiment of the present invention is 100 to 1000 g / m 2 The range is preferably within this range. If the range is within this range, it can be easily used as a towel fabric. 2 , and medium-weight fabrics have a basis weight of 250 to 500 g / m 2 , thickness is 500 to 1000 g / m 2 In addition, 100 g / m 2 Those that are less than 1000 g / m are thin and have no bulk. 2 Anything over that is too thick and heavy, and neither is desirable.

[0024] In one embodiment of the method for manufacturing a towel fabric according to the present invention, the pile yarns, warp yarns, and weft yarns are all unsized, and the towel fabric is preferably woven using a loom. Examples of looms include air jet looms, water jet looms, shuttle looms, and rapier looms, but the most efficient air jet loom is preferred. Air looms can be used for weaving at a loom rotation speed of 300 to 500 rpm.

[0025] Furthermore, in this invention, cotton is the most superior in terms of texture, absorbency, moisture absorption, and ease of handling as a towel. However, cotton can also be blended with small amounts of linen, silk, rayon, polyester, nylon, cupra, acetate, or wool. Blends of rayon, cupra, and acetate provide moisture absorption, while wool provides heat retention. Blends of polyester and nylon provide quick-drying properties. Following the cotton processing process, the woven fabric is desized using a jet dyeing machine and then scoured under standard cotton scouring conditions (a constant temperature of 95-98°C, a hold time of 50 minutes, diluted caustic soda solution, and an alcohol ethoxylate-added bath). Following scouring, the fabric is then bleached under standard conditions (98°C, 50 minutes, hydrogen peroxide solution). The scouring and bleaching process is also called bleaching. The fabric is then dehydrated and set in a tenter to achieve an off-white finish. This bleaching process also involves hot water treatment. The water-soluble fiber yarns are dissolved and removed by the hot water treatment.

[0026] When dyeing after scouring and bleaching, cotton is dyed with a reactive dye (60-80°C, 40 minutes). Also, when polyester fibers are blended, disperse dyes are used (130°C, 40 minutes). When dyeing fabrics containing cotton and polyester, in addition to solid dyeing using this two-bath process, disperse and reactive dyes can be used separately to dye different colors or chambray (shades). Printing is also possible on scoured and bleached off-white fabric. In the case of pre-dyed polyester yarn, crimping can be developed simultaneously with scouring, followed by bleaching and dyeing, and then woven to produce pre-dyed towel fabric. In the case of pre-dyed cotton yarn, the yarn is scoured, bleached, dyed, and then woven to produce pre-dyed towel fabric. In this way, the present invention allows for the commercialization of products with excellent color and design properties through a variety of dyeing methods.

[0027] The towel fabric according to one embodiment of the present invention is suitable for use as a fabric for bath towels (towels for after a bath), bath towels, bedding light towels, face towels, towel handkerchiefs, sports towels, bathrobes, towel blankets, as well as for clothing, socks, rugs, bedding, etc.

[0028] The following description will be made with reference to the drawings. In the following drawings, the same reference numerals indicate the same parts. Figure 1 is a schematic side view of an air spun yarn (shive spun yarn) 10 used in one embodiment of the present invention. In this air spun yarn 10, the core fibers 11 are parallel to the yarn axis, and the sheath fibers 12 are twisted in one direction. Figure 2 is a schematic side view of a pile yarn 14 in one embodiment of the present invention. In this pile yarn 14, the air spun yarn 10 and the water-soluble fiber yarn 13 are twisted together in the untwisting direction of the sheath fibers 12, the core fibers 11 are twisted in the opposite direction by the number of twists of the water-soluble fiber yarn 13, and the sheath fibers 12 are untwisted by the number of twists of the water-soluble fiber yarn 13. In other words, the core fibers 11 are twisted in one direction, the sheath fibers 12 are arranged parallel to the yarn axis, and the water-soluble fiber yarn 13 is wrapped around it, with the winding direction of the water-soluble fiber yarn 13 being opposite to the twist direction of the core fibers 11. As a result, the sheath fibers 12 are in an untwisted or loosely twisted state.

This towel fabric 1 is composed of warp pile yarns 2a, 2b, weft yarns 3, and warp yarns 4a, 4b, and the warp pile yarns 2a, 2b form loop piles while being retained in the ground weave composed of the weft yarns 3 and warp yarns 4a, 4b. The obtained towel fabric 1 is cut to a predetermined size and edge-processed to form towels.

[0030] Figure 4 is a woven fabric diagram of a towel fabric according to one embodiment of the present invention. This woven fabric is a three-pick terry motion weave. The warp pile yarns cross over every three weft ground yarns. The warp ground yarns G and the warp pile yarns P are arranged alternately. The weft yarns 1 to 3 indicate the order. In Figure 4, as viewed from the warp, black and x indicate floating yarns, and white indicates sinking yarns.

[0031] The following provides a more detailed explanation using examples. The present invention is not limited to the following examples. <Evaluation of the texture of finished towel fabric> (1) Evaluation of soft texture The softness of the texture is expressed as the volume per 1 g of towel fabric, and is determined by the bulkiness using the following formula. The higher the value, the softer and better the texture. The thickness was measured in accordance with JIS L-1096 (2010) 8.5 bulkiness test, and the basis weight was measured by precisely weighing the weight of a 1 m square. Measurements were taken at five points and the average value was expressed. Bulkiness (cm 3 / g) = thickness (mm) / basis weight (g / m 2 ) × 1000 (2) Evaluation of fluffy texture The towel fabric was compressed at a constant speed using a compression measuring device: KES-G5 (manufactured by Kato Tech Co., Ltd.), and the compression work: WC = (gf.cm 2 ) was determined. Measurements were taken at five locations and the average value was expressed. The WC value is the energy required to compress the fabric, and the larger the value, the better the towel is compressed, the greater the volume and fluffiness, and the better the result. (3) Evaluation of Washing Durability of Texture The towel fabric was washed 20 times in a washing machine according to JIS L-0217 (1995), Method 103. After drying, the compression work: WC = (gf.cm 2) was measured at five locations and the average value was expressed. The smaller the difference in WC value before and after washing, the less the loss of fluffy texture due to washing, and the better the durability. (4) Evaluation of water drainage after washing A 35 cm wide towel fabric was cut to a length of 80 g, weighed to one decimal place, and soaked in water for 20 minutes. The wet towel fabric was then removed and centrifuged in the spin tub of a washing machine for 4 minutes, then weighed accurately, and the residual moisture content (%) of the towel fabric was calculated using the following formula. The smaller the value, the better the water drainage. Better water drainage tends to result in faster subsequent drying speed. Three measurements were taken and the average value was expressed. Residual moisture content of fabric (%) = (weight of fabric after immersion in water and dehydration (W1)) - (weight of fabric before immersion in water (W0)) / (weight of fabric before immersion in water (W0)) x 100 (5) Evaluation of fuzz shedding due to washing of towel fabric Fuzz shedding due to washing was measured in accordance with JIS L0217 (1995), method 103. The fuzz shedding rate (%) was calculated using the following formula, with a smaller value indicating less fuzz shedding and better performance. Five measurements were taken and the average value was calculated. Fuzz shedding rate (%) = (weight of fuzz removed after washing (g1)) / (weight of towel before washing (g0)) x 100 (6) Evaluation of water absorbency (modified Larose method) Measurements were made five times according to the modified Larose method of JIS L 1907 (2010), and the average value was calculated. The Larose index (water absorption index) was calculated according to the following formula. Larose Index (Water Absorption Index) = 2545V x 1411W + 79 V: Maximum water absorption rate (ml / s), W: Water absorption amount at maximum water absorption rate (ml). The higher the value, the faster and more water is absorbed from the skin, which is preferable. (7) Water Absorption Rate (Drop Method) The water absorption rate of terry cloth was measured based on the Vuillet method, a drop method of JIS L 1907 (2010). The test outline was to drop a drop of water onto the terry cloth from a height of 10 cm, and measure the water absorption time (seconds) until the mirror-like surface of the drop disappeared three times, and calculate the average value. The shorter the time, the faster and better the water absorption.<Test Method for Rewetting Rate> The rewetting rate is described in Patent Publication No. 6991633, proposed by the present applicant. This test method involves dropping water onto a fabric test specimen, allowing it to absorb the water, absorbing it with filter paper, and evaluating the fabric's ability to retain the water. This test method, known as the rewetting rate, is consistent with the assessment of water absorbency perceived by humans when using fiber fabrics such as towels. The lower the rewetting rate, the greater the fabric's water absorbency and the better it is evaluated to be. (1) Test Environment and Other Conditions: The test environment was standard conditions, with a temperature of 20±4°C and a relative humidity of 65±4% RH. The filter paper used was stored for at least 24 hours under standard conditions, with a temperature of 20±4°C and a relative humidity of 65±4% RH. The test specimens used were stored for at least 24 hours under standard conditions, with a temperature of 20±4°C and a relative humidity of 65±4% RH. The dripped water was at a temperature of 20±15°C (5-35°C). (2) Operating Procedure: The test specimen of the fiber towel fabric measured 10 cm in length and 10 cm in width. The test specimen was placed on the specimen stand. The filter paper used was made from α-cellulose, conforming to JIS P 3801 Class 1 standard, with a diameter of 110 mm and a thickness of 0.22 mm, and was weighed. The filter paper used was Advantec's "Circular Qualitative Filter Paper No. 1." 0.8 ml of water was measured into a pipette and dropped onto the test specimen. The test specimen was allowed to absorb the water for 5 seconds. The filter paper was placed on top and a load of 1.3 kg (1274 Pa) was placed on top. The load was then removed after 5 seconds. The weight of the filter paper after water absorption was measured. (3) Calculation of Water Rewet Rate: This was calculated using the following formula. W = [(B - A) / A] x 100 Where, W: Water rewet rate (%) A: Weight (g) of filter paper before measurement B: Weight (g) of filter paper after water absorption The lower the value of the water rewet rate, the better. <Pile Pile Standing Property> A side photograph (30x magnification) of the pile portion of the towel fabric was observed using an optical microscope.

[0032] (Example 1) 1. Fibers Used (1) Warp Pile Yarns Cotton with a fiber length of 31.3 mm and a micronaire of 4.4 μg / inch was used as the warp pile fiber. The fiber was 100% combed cotton, with a sliver thickness of 320 Gr / 6 yd. A sheath-core whirling air spun yarn with a cotton count of 40S was obtained, with the center (core) of the spun yarn being 20-30% parallel fiber and the outer layer (sheath) being 80-70% (Figure 1). Next, the whirling air spun yarn was plied with an 80-count single yarn and a 38 mm fiber length water-soluble vinylon spun yarn using a ring twister. The twisting coefficient K was set to 2.7, and the plying direction was the untwisting direction of the sheath fiber (wrapped fiber) of the whirling air spun yarn, leaving the sheath fiber in a nearly untwisted state (Figure 2). (2) Warp yarn: Cotton with a fiber length of 31.3 mm and a micronaire of 4.4 μg / inch was used, and a ring-spun yarn made of 100% cotton fiber, a two-ply yarn with a cotton count of 30S (394 decitex) was used (30S / 2). (3) Weft yarn: Cotton with a fiber length of 31.3 mm and a micronaire of 4.4 μg / inch was used, and a ring-spun yarn made of 100% cotton fiber, a single-ply yarn with a cotton count of 20S (295 decitex) was used (20S / 1). 2. Weaving of towel fabric: The warp pile yarns, warp yarns, and weft yarns were unsized and woven on an air loom at 400 rpm to produce the loop pile fabric shown in Figures 3 and 4. The warp pile yarn was fed at a rate of 8.3 times that of the warp yarns. In this way, a double-sided pile fabric with a warp density of 60 threads / 2 inches, a weft density of 54 threads / inch, and a pile length of 1.18 cm was produced. After scouring and bleaching this pile woven fabric (no desizing required), it was heat-treated in a tenter and finished. The mass per unit area (basis weight) of this fabric was 313 g / m 2 3. Scouring and finishing of towel fabric Next, this greige fabric was scoured in a dilute caustic soda and alcohol ethoxylate-added bath at 98°C for 50 minutes in accordance with the usual method for processing cotton. Next, it was bleached in a hydrogen peroxide bath at 98°C for 50 minutes in the usual method, and set at 135°C in a tenter and finished (off-white finish). The pile length was 1.18 cm.

[0033] Comparative Example 1 A towel was woven and desized in the same manner as in Example 1, except that 100% cotton ring-spun yarn, a single yarn with a cotton count of 40S, was used as the warp pile yarn and sizing was performed. The results are shown in Table 2.

[0034]

[0035] As is clear from Table 2, the towel fabric of Example 1 had the following advantages over Comparative Example 1: (1) Less shedding of fuzz. (2) High volume. (3) Less loss of fluffiness after washing. In other words, less deterioration after washing. (4) Less rewetting, providing a comfortable wiping experience.
