Description

Knitted fabrics and clothing containing them

[0001] The present invention relates to knitted fabrics and garments.

[0002] Conventionally, attempts have been made to combine the warmth of spun yarn with the wash-and-wear properties of long fibers to produce heat-retaining fiber products for innerwear. For example, knitted fabrics containing viscose rayon fibers, cationic dyeable polyester fibers, polyacrylic synthetic fibers, and polyurethane elastic fibers are known (see, for example, Patent Documents 1 and 2).

[0003] Also, attempts to improve heat retention by using an interlock weave and adopting a specific loop balance to incorporate dead air into the knitted fabric are known (see, for example, Patent Document 3).

[0004] Patent No. 6447128 Patent No. 5453863 Patent No. 6635972

[0005] When considering the heat retention of clothing, it is preferable to increase the bulk by using spun yarn and long fibers as described in Patent Documents 1 and 2, or by using an interlock structure as described in Patent Document 3.

[0006] On the other hand, for example, underwear, thin, soft, and smooth knitted fabrics are preferred. However, according to the findings of the present inventors, thin and soft single knit structures have uneven surfaces against the skin, which makes the feel of the fabric difficult. Furthermore, when spun yarn and continuous fibers are used to improve heat retention and wash-and-wear properties, as described in Patent Documents 1 and 2, for example, the spun yarn is thick and the continuous fibers are thin, which makes the unevenness of the single knit fabric more pronounced.

[0007] Furthermore, the technology of Patent Document 3 has excellent heat retention and does not cause the problem of surface smoothness, but causes problems with thickness and flexibility.

[0008] Therefore, an object of the present invention is to provide a knitted fabric that is thin and soft, and has excellent skin smoothness, heat retention, and wash-and-wear properties, and to provide clothing containing the same.

[0009] In order to achieve the above-mentioned objects, the present invention has the following configurations. (1) A knitted fabric in which courses of fiber 1 made of spun yarn and courses of fiber 2 made of continuous fibers are alternately repeated in the warp direction, wherein the ratio (D2 / D1) of the total fineness D2 of fiber 2 to the total fineness D1 of fiber 1 is in the range of 0.50 to 0.90, and the ratio (L2 / L1) of the yarn length L2 of fiber 2 to the yarn length L1 of fiber 1 per 100 wales is greater than 1.00. (2) The knitted fabric according to (1) above, in which the spun yarn contains a cellulose fiber and an acrylic fiber. (3) The knitted fabric according to (1) or (2) above, in which the total fineness of fiber 1 is 70 to 150 decitex. (4) The knitted fabric according to any of (1) to (3) above, in which the continuous fibers are cation-dyeable polyester continuous fibers. (5) The knitted fabric according to any one of (1) to (4) above, wherein the total fineness of the fiber 2 is 33 to 135 decitex. (6) The knitted fabric according to any one of (1) to (5) above, further comprising an elastic fiber. (7) The knitted fabric according to any one of (1) to (6) above, further comprising an elastic fiber course. (8) The knitted fabric according to any one of (1) to (7) above, wherein the ratio (L2 / L1) of the yarn length L2 of the fiber 2 to the yarn length L1 of the fiber 1 per 100 wales is in the range of 1.02 to 1.20. (9) Clothing comprising the knitted fabric according to any one of (1) to (8) above. (10) Undergarments or underwear made from the knitted fabric according to any one of (1) to (8) above.

[0010] According to the present invention, it is possible to obtain a knitted fabric that is excellent in smoothness against the skin, heat retention, and wash-and-wear properties, and clothing containing the same.

[0011] FIG. 1 is a schematic diagram of a knitted fabric illustrating one embodiment of the present invention.

[0012] An embodiment of the knitted fabric of the present invention will be described in detail. The knitted fabric of the present invention includes a course of fiber 1 made of spun yarn and a course of fiber 2 made of long fibers. The spun yarn can improve heat retention. Furthermore, the long fibers not only provide excellent wash-and-wear properties, but also improve the strength and wrinkle resistance of the single knit fabric in the present invention. Fiber 1 may contain materials other than spun yarn, and fiber 2 may contain materials other than long fibers, as long as they do not impair the effects of the present invention.

[0013] In the present invention, the spun yarn is not particularly limited, and one or more of natural fibers such as cotton, linen, and wool, chemical fibers such as rayon and acetate, and synthetic fibers such as polyester, acrylic, and nylon may be used. In the present invention, it is preferable that the spun yarn contains cellulose fibers such as cotton, rayon, and acetate, and acrylic fibers, from the viewpoint of heat retention.

[0014] The cellulose fiber is not particularly limited, but is preferably a viscose rayon-based fiber. Viscose rayon-based fibers are regenerated fibers spun using the viscose method, and are short fibers that refer to viscose rayon and saponified acetate. The mass ratio of the cellulose fiber to the spun yarn is preferably 15% by mass or more. By containing cellulose fiber in the above range, a knitted fabric with excellent durability and hygroscopic heat generation properties can be obtained. Because the knitted fabric has hygroscopic heat generation properties, the knitted fabric generates heat due to water vapor emitted from the human body when worn, thereby raising the temperature of the garment. Furthermore, the mass ratio of the cellulose fiber to the spun yarn is preferably 60% by mass or less, and more preferably 40% by mass or less. By setting the upper limit of the cellulose fiber content within the above range, wrinkles after washing can be further suppressed.

[0015] The acrylic fiber is not particularly limited, and in addition to regular polyacrylic fibers made from polyacrylonitrile, it may be a polyacrylic fiber obtained by copolymerizing or adding other compounds based on an acrylic composition, or may be a polyacrylic fiber modified to be anti-pilling or water-absorbent. The mass ratio of the acrylic fiber to the spun yarn is preferably 40% by mass or more, and more preferably 60% by mass or more. By containing acrylic fiber within the above range, the effect of further improving heat retention is achieved. Furthermore, the mass ratio of the acrylic fiber to the spun yarn is preferably 80% by mass or less, and more preferably 70% by mass or less. By setting the upper limit of the acrylic fiber content within the above range, the content of, for example, cellulose fiber, etc. can be relatively increased, thereby improving moisture absorption and heat generation properties.

[0016] The single fiber fineness of the acrylic fiber is preferably 0.6 dtex or more in terms of softer texture, improved heat retention, improved spinnability, improved strength, etc. In terms of texture, it is preferably 2.2 dtex or less, more preferably 1.5 dtex or less.

[0017] Considering that the knitted fabric of the present invention can be preferably used for underwear, T-shirts, and the like that come into direct contact with human skin, the total fineness of fiber 1 is preferably 150 decitex or less, more preferably 130 decitex or less, in terms of excellent feel and softness. Furthermore, in terms of excellent heat retention, the total fineness of fiber 1 is preferably 70 decitex or more, more preferably 90 decitex or more. Considering its intended use, the single fiber fineness of the spun yarn is preferably 0.5 decitex to 2.5 decitex. Furthermore, the spun yarn is composed of staple fibers, the fiber length of which is preferably in the range of 38 to 52 mm.

[0018] In the present invention, the long fibers are not particularly limited, and monofilaments or multifilaments of chemical fibers such as rayon or acetate, or synthetic fibers such as polyester, nylon, or acrylic can be used as appropriate. Among these, polyester long fibers are preferred in terms of strength and wrinkle resistance. Examples of polyester long fibers include polyethylene terephthalate long fibers, polybutylene terephthalate long fibers, polytrimethylene terephthalate long fibers, and long fibers of copolymers thereof. In addition to single-component long fibers, bicomponent long fibers having cross sections such as side-by-side or core-sheath can also be used. In the present invention, taking into consideration dyeability with other materials, cationic dyeable polyester long fibers that can be dyed with cationic dyes, such as polyethylene terephthalate long fibers copolymerized with 1.0 to 3.0 mol % of a 5-sodium sulfoisophthalic acid component, are preferred. The use of cationic dyeable polyester long fibers allows for dyeing at lower temperatures than ordinary polyester fibers and also allows for dyeing with the same dyes as acrylic fibers. Furthermore, the cationic dyeable polyester long fiber exhibits excellent color development and fastness at temperatures of 105°C to 115°C, and therefore can suppress deterioration of other fibers, particularly polyurethane elastic fibers, due to heat.

[0019] Cationic dyeable polyester filaments can be produced by any commonly known method for producing polyesters. Furthermore, as is commonly known, cationic dyeability of ordinary polyesters can be achieved, for example, by copolymerizing 1.0 to 3.0 mol % of a 5-sodium sulfoisophthalic acid component with ordinary polyester.

[0020] In the present invention, fiber 2 is preferably a multifilament, and in this case, the number of filaments is preferably 24 to 192. Furthermore, considering that the knitted fabric of the present invention can be preferably used for underwear, T-shirts, and the like that come into direct contact with human skin, the total fineness of fiber 2 is preferably 135 decitex or less, more preferably 120 decitex or less, and even more preferably 100 decitex or less, in terms of excellent feel and softness. Furthermore, in terms of excellent strength, the total fineness is preferably 33 decitex or more, more preferably 40 decitex or more, and even more preferably 50 decitex or more.

[0021] The mass ratio of fiber 2 to the knitted fabric is preferably 20% by mass or more, and more preferably 30% by mass or more. By setting it in this range, it is possible to further suppress the occurrence of wrinkles in the fiber structure after washing. Furthermore, the mass ratio of fiber 2 to the knitted fabric is preferably 60% by mass or less, and more preferably 50% by mass or less. By setting it in this range, it is possible to improve heat retention.

[0022] In the present invention, it is preferable that the above-mentioned fiber 1 and fiber 2 exist in different courses.

[0023] In terms of wearing comfort, it is a preferred embodiment of the knitted fabric of the present invention that it further contains elastic fiber. More preferably, it contains courses of elastic fiber. The elastic fiber is preferably contained in an amount of 3% by mass or more of the knitted fabric, and more preferably 5% by mass or more. By containing the elastic fiber in the above range, it is possible to increase the appropriate elongation and the gaps between the knitted fabric loops, thereby allowing the fabric to smoothly follow the movement of the body and further improving wearing comfort. Furthermore, it is preferable that the elastic fiber is contained in a proportion of 15% by mass or less of the knitted fabric, and more preferably 13% by mass or less. By containing the elastic fiber in the above range, it is possible to reduce excessive tightness caused by the elastic fiber when worn, and improve wearing comfort.

[0024] As the elastic fiber, polyurethane-based elastic fibers are preferred in terms of cost and stretchability. Polyurethane-based elastic fibers preferably have an elastic recovery rate of 90% or more when stretched 200%. By setting the elasticity within the above range, excellent durability can be obtained against repeated wearing. Furthermore, the knitting structure and knitting density can be set as desired depending on the intended application. Furthermore, since polyurethane-based elastic fibers are preferably used for underwear and T-shirts that come into direct contact with the skin, the total fineness is preferably 15 to 50 decitex, more preferably in the range of 20 to 45 decitex. Furthermore, polyurethane-based elastic fibers are usually used as long fibers (filaments), and polyurethane-based elastic fibers with 1 to 3 filaments are preferably used.

[0025] Furthermore, the knitted fabric of the present invention may further contain, in addition to the above, polyester fibers other than those mentioned above, polyester fibers in which a third component is copolymerized with polyester, polyamide fibers, regenerated cellulose fibers, and protein fibers such as wool and silk, etc. The above fibers constituting the knitted fabric are used in the form of mixed fibers, mixed spinning, mixed weaving, inter-knitted, etc.

[0026] In the knitted fabric of the present invention, the above-mentioned courses of fiber 1 and courses of fiber 2 are alternately repeated in the warp direction. This allows for improved heat retention and strength. The form in which they are alternately repeated is not particularly limited, and may be, for example, as exemplified in the knitted fabric (4) of Figure 1, in which fiber 1 (1) and fiber 2 (2) are alternately repeated in each row, or in which each fiber is grouped together in two or more rows.

[0027] In the present invention, the ratio (D2 / D1) of the total fineness D2 of fiber 2 to the total fineness D1 of fiber 1 is in the range of 0.50 to 0.90. Here, both D1 and D2 are expressed in decitex. In the present invention, the cotton count used as a fineness unit for spun yarn is converted to decitex by dividing 5910 by the cotton count. Specific measurement methods are as described in the Examples below.

[0028] The ratio (D2 / D1) of the total fineness D2 to D1 in the knitted fabric of the present invention is 0.50 or more, preferably 0.55 or more, and more preferably 0.60 or more. Furthermore, the ratio (D2 / D1) of the total fineness D2 to D1 in the knitted fabric of the present invention is 0.90 or less, preferably 0.85 or less, and more preferably 0.80 or less. Most preferably, (D2 / D1) is 0.60 or more and 0.80 or less. By keeping the ratio within the above range, excellent smoothness and excellent feel can be obtained even in a single knit structure.

[0029] Furthermore, in the knitted fabric of the present invention, the ratio (L2 / L1) of the yarn length L2 of fiber 2 to the yarn length L1 of fiber 1 per 100 wales is greater than 1.00. It is preferably 1.02 or greater, more preferably 1.05 or greater, and even more preferably 1.10 or greater. The upper limit is preferably 1.20 or less. It is most preferable that (L2 / L1) is 1.05 or greater and 1.20 or less. By keeping the ratio (L2 / L1) of yarn length L2 to L1 within the above range, excellent smoothness and excellent feel can be obtained even in a single knit structure. Therefore, by keeping (D2 / D1) in the range of 0.60 or greater and 0.80 or less and (L2 / L1) in the range of 1.05 or greater and 1.20 or less, the most excellent smoothness and excellent feel can be obtained.

[0030] It is generally known that the thinner the fiber, the better the flexibility and feel on the skin. In the present invention, however, it has been discovered that by setting the ratio of the total fineness D2 to D1 (D2 / D1) and the ratio of the yarn lengths L2 to L1 (L2 / L1) within the above-mentioned specific ranges, respectively, the unevenness of the skin surface formed by the arrangement of fibers 1 and 2 is eliminated, thereby achieving extremely excellent smoothness and feel on the skin.

[0031] Next, the knitted fabric of the present invention is not particularly limited as long as it is a single knit structure. A single knit structure can achieve thinness and flexibility. In terms of smoothness and feel, structures such as jersey and inlay are preferred.

[0032] The clothing of the present invention includes the knitted fabric of the present invention described above. The knitted fabric of the present invention preferably accounts for 50% by mass or more of the clothing, more preferably 80% by mass or more. The clothing is not particularly limited as long as it is clothing worn on the body, such as outerwear such as underwear, T-shirts, blousons, slacks, and skirts, and underwear such as tights, spats, camisoles, and pants, and is preferably used for various clothing. In particular, clothing that comes into direct contact with the skin, such as underwear, underwear, T-shirts, tights, spats, and camisoles, is preferred because it can better demonstrate the effects of the present invention. Underwear and underwear are particularly preferred.

[0033] Next, the knitted fabric of the present invention will be specifically described based on examples. Here, the methods for evaluating each performance in the examples etc. are as follows.

[0034] (1) Total fineness, cotton count The cotton count of the spun yarn was measured in accordance with JIS L1095 (2010) 9.4.1. The cotton count of the continuous fiber was measured in accordance with JIS L1013 (2010) 8.3 A method, and the values ​​were rounded to the nearest integer.

[0035] (2) Yarn length (stitch length) The yarn was unraveled from the knitted fabric obtained after processing, and the stitch length (mm) for 100 wales was measured in accordance with JIS L1096 (2020) 8.8, and rounded to two decimal places.

[0036] (3) Ratio of total fineness D2 of fiber 2 to total fineness D1 of fiber 1 (D2 / D1) For spun yarn, the results measured in (1) above were converted to decitex. The cotton count obtained in (1) above was converted to decitex using the following formula according to the determined count, and the result was rounded to the nearest integer to obtain D1. D2 / D1 was calculated using D1 and D2, and rounded to two decimal places. D1 = 5,910 / cotton count (4) Ratio of yarn length L2 of fiber 2 to yarn length L1 of fiber 1 per 100 wales (L2 / L1) This was calculated using the results measured in (2) above, and rounded to two decimal places.

[0037] (5) Smoothness (Tribomaster) Using a Tribomaster TL201Ts manufactured by Trinity Lab Co., Ltd. as a measuring device, the sample was stretched in all directions under the test conditions of a pressure load of 10 g, a friction speed of 50 mm / sec, and the measurement was performed on the back side of the measurement surface, and the kinetic friction coefficient was determined by measuring in the bias direction using a skin imitation sheet.

[0038] (6) Heat retention (CLO value) Measured in accordance with ASTM D1518-85 using an ASTM type heat retention tester at a test room temperature of 20°C, a test room humidity of 65% RH, and with the back of the fabric facing the hot plate.

[0039] Example 1 40% by mass of viscose rayon staple (single fiber fineness 1.4 dtex, 38 mm) and 60% by mass of polyacrylic fiber staple (single fiber fineness 1.0 dtex, 45 mm) were mixed by card mixing to obtain a 125 dtex spun yarn (fiber 1).

[0040] The spun yarn thus obtained, cationic dyeable polyester long fiber (84 dtex - 72 filaments) (fiber 2), and polyurethane-based elastic fiber (33 dtex - 2 filaments) were knitted into a plain weave on a single knit knitting machine with a 76.2 cm bobbin diameter and a gauge of 28 / 2.54 cm. The yarn lengths at the time of knitting were designed to be 275.00 mm for the spun yarn and 315.00 mm for the cationic dyeable polyester long fiber after the following processing, and were repeated alternately in the warp direction. The polyurethane-based elastic fiber was then knitted in parallel with the spun yarn and long fiber. The knitted fabric was 30% by weight of polyacrylic fiber, 20% by weight of viscose rayon fiber, 38% by weight of cationic dyeable polyester fiber, and 12% by weight of polyurethane-based elastic fiber.

[0041] The thus obtained greige fabric was processed through the steps of heat setting (190°C, 30 seconds)-scouring (70°C)-dyeing (115°C)-drying (130°C)-heat setting (130°C).

[0042] The yarn length, smoothness, and heat retention of the fabric thus obtained were evaluated. The results are shown in Table 1. The knitted fabric obtained had a good balance between D2 / D1 and L2 / L1, and was particularly good in both smoothness and heat retention.

[0043] (Example 2) In Example 1, the yarn lengths after processing were designed to be 255.00 mm for the spun yarn and 260.00 mm for the cationic dyeable polyester long fiber, and the polyurethane elastic fiber was 22 dtex-2 filament, but knitting and processing were carried out in the same manner as in Example 1. The obtained fabric was evaluated in the same manner as in Example 1, and as shown in Table 1, a knitted fabric with good smoothness and heat retention was obtained.

[0044] Example 3 40% by mass of viscose rayon staple (single fiber fineness 1.4 dtex, 38 mm) and 60% by mass of polyacrylic fiber staple (single fiber fineness 1.0 dtex, 45 mm) were mixed by card mixing to obtain a spun yarn of 98 dtex.

[0045] The spun yarn thus obtained, cationic dyeable polyester long fiber (56 dtex - 72 filaments), and polyurethane-based elastic fiber (22 dtex - 2 filaments) were knitted into a plain weave on a single knit knitting machine with a 76.2 cm bobbin diameter and a gauge of 28 / 2.54 cm. The yarn lengths at the time of knitting were designed to be 255.00 mm for the spun yarn and 295.00 mm for the cationic dyeable polyester long fiber after the following processing, and were repeated alternately in the warp direction. The polyurethane-based elastic fiber was then knitted in parallel with the spun yarn and long fiber. The knitted fabric was 32% by weight of polyacrylic fiber, 23% by weight of viscose rayon fiber, 32% by weight of cationic dyeable polyester fiber, and 13% by weight of polyurethane-based elastic fiber.

[0046] The thus obtained greige fabric was processed through the steps of heat setting (190°C, 30 seconds)-scouring (70°C)-dyeing (115°C)-drying (130°C)-heat setting (130°C).

[0047] As in Example 1 above, yarn length, smoothness, and heat retention were evaluated, and as a result, a knitted fabric with good smoothness and heat retention was obtained.

[0048] (Example 4) Knitting and processing were carried out in the same manner as in Example 3, except that the yarn lengths after processing were designed to be 255.00 mm for the spun yarn and 268.00 mm for the cationic dyeable polyester long fiber. The obtained fabric was evaluated in the same manner as in Example 1, and as shown in Table 1, a knitted fabric with good smoothness and heat retention was obtained.

[0049] Comparative Example 1 In Example 1, a plain weave was knitted using 110 dtex cationic dyeable polyester long fiber instead of the spun yarn. The yarn lengths during knitting were designed to be 275.00 mm for the 110 dtex cationic dyeable polyester long fiber and 295.00 mm for the 84 dtex cationic dyeable polyester long fiber, alternately repeated in the warp direction after the following processing, and polyurethane elastic fiber was aligned with each long fiber for knitting. The knitted fabric was 88% by weight of cationic dyeable polyester fiber and 12% by weight of polyurethane elastic fiber.

[0050] The thus obtained greige fabric was processed through the steps of heat setting (190°C, 30 seconds)-scouring (70°C)-dyeing (115°C)-drying (130°C)-heat setting (130°C).

[0051] As in Example 1 above, the thread length, smoothness, and heat retention were evaluated, and it was confirmed that the smoothness was good, but the heat retention was poor.

[0052] Comparative Example 2 30% by mass of cotton and 70% by mass of polyacrylic staple fiber (single fiber fineness 1.0 dtex, 45 mm) were mixed by card mixing to obtain a spun yarn of 147 dtex (cotton count 40).

[0053] The spun yarn thus obtained, cationic dyeable polyester long fiber (33 dtex - 24 filaments), and polyurethane elastic fiber (22 dtex - 2 filaments) were knitted into a plain weave on a single knit knitting machine with a 76.2 cm bobbin diameter and a gauge of 28 / 2.54 cm. The yarn lengths at the time of knitting were designed to be 265.00 mm for the spun yarn and 295.00 mm for the cationic dyeable polyester long fiber after the following processing, and were repeated alternately in the warp direction. The polyurethane elastic fiber was then aligned with each long fiber and knitted. The knitted fabric was 21% by weight of cotton, 50% by weight of polyacrylic fiber, 17% by weight of cationic dyeable polyester fiber, and 12% by weight of polyurethane elastic fiber.

[0054] The thus obtained greige fabric was processed through the steps of heat setting (190°C, 30 seconds)-scouring (70°C)-dyeing (115°C)-drying (130°C)-heat setting (130°C).

[0055] As in Example 1 above, the thread length, smoothness, and heat retention were evaluated, and it was confirmed that the heat retention was good, but the smoothness was poor.

[0056] Comparative Example 3 35% by mass of viscose rayon staple (single fiber fineness 1.4 dtex, 38 mm) and 65% by mass of polyacrylic fiber staple (single fiber fineness 1.0 dtex, 45 mm) were mixed by card mixing to obtain a spun yarn of 147 dtex.

[0057] The spun yarn thus obtained, cationic dyeable polyester long fiber (90 dtex - 48 filaments), and polyurethane-based elastic fiber (28 dtex - 2 filaments) were knitted into a plain weave on a single knit knitting machine with a 76.2 cm bobbin diameter and a gauge of 28 / 2.54 cm. The yarn lengths at the time of knitting were designed to be 265.00 mm for the spun yarn and 250.00 mm for the cationic dyeable polyester long fiber after the following processing, and were repeated alternately in the warp direction. The polyurethane-based elastic fiber was then aligned with each long fiber and knitted. The knitted fabric was composed of 20% by weight of viscose rayon, 38% by weight of polyacrylic fiber, 34% by weight of cationic dyeable polyester fiber, and 8% by weight of polyurethane-based elastic fiber.

[0058] The thus obtained greige fabric was processed through the steps of heat setting (190°C, 30 seconds)-scouring (70°C)-dyeing (115°C)-drying (130°C)-heat setting (130°C).
