Description

Knitted fabrics and underwear

[0001] This invention relates to knitted fabrics and underwear.

[0002] Conventionally, in underwear materials, the use of hydrophilic cellulose fibers has been used extensively to improve moisture absorption and reduce stuffiness during wear. However, the increased hydrophilicity has presented challenges in quick-drying performance. To address this, knitted fabrics composed of cellulose spun yarn, polyester filaments, and polyurethane (see, for example, Patent Document 1), or woven fabrics containing polypropylene fibers that constitute the back layer have been proposed (see, for example, Patent Document 2). Furthermore, to obtain appropriate moisture absorption and quick-drying properties, woven or knitted fabrics composed of a twisted composite yarn of polyester composite fiber filament yarn in which two polyester polymers with different intrinsic viscosities are bonded side-by-side, and cellulose fiber filament yarn with an official moisture content of 2-8% have also been proposed (see, for example, Patent Document 3).

[0004] However, Patent Document 1 specifies a blending ratio of cellulose-based spun yarn of 20-40% by weight from the standpoint of quick-drying properties, and further improvement in water absorption was desired. In addition, Patent Document 2 suffers from a lack of design appeal because the polypropylene fibers are not dyed. Patent Document 3, being a twisted composite yarn, also suffers from the same problem as Patent Document 2 in that it suffers from a lack of design appeal and does not possess sufficient water absorption and quick-drying performance.

[0005] The present invention has been made in view of the above, and aims to provide knitted fabrics and underwear that have improved water absorption, quick drying, and breathability, and that can also have an excellent texture when configured in a preferred manner.

[0006] To solve the above-mentioned problems and achieve the objective, the following configuration is provided: (1) A knitted fabric comprising at least cellulose fibers and polyester crimped yarn, wherein the knitted fabric comprises at least the cellulose fibers on a first surface and at least the polyester crimped yarn on a second surface, the knitted fabric has a plating structure, and the proportion of the cellulose fibers is 50 to 70% by mass. (2) The knitted fabric according to (1) above, wherein the polyester crimped yarn is a polyester crimped yarn comprising at least two types of polyester polymers. (3) The knitted fabric according to (1) or (2) above, wherein the time measured by the dropping method after 10 washes is 3 seconds or less, and the diffusible residual moisture content is 30% or less after 1 hour after 10 washes. (4) A fabric with a basis weight of 100 to 170 g / m ２ (1) to (3) above, wherein the knitted fabric is as described above and has a drape coefficient of 0.22 or more as defined in JIS L 1096 G method (2020). (5) The knitted fabric is as described above and has a stiffness of 15 to 40 mm as defined in JIS L 1018 (2020) cantilever method. (6) The knitted fabric is as described above and has a cellulose fiber made of cotton. (7) The knitted fabric is as described above and has a drape coefficient of 0.22 or more as defined in JIS L 1096 G method (2020). (8) The knitted fabric is as described above and has a drape coefficient of 0.22 or more as defined in JIS L 1018 (2020). (9) The knitted fabric is as described above and has a drape coefficient of 0.22 or more as defined in JIS L 1096 G method (2020). (1) to (2) above, wherein the

[0007] According to the present invention, it is possible to provide knitted fabrics and underwear that are excellent in water absorption and quick drying properties and in suppressing stuffiness, and in a preferred embodiment, also have excellent texture such as firmness.

[0008] Figure 1 is a schematic cross-sectional view showing an example of a knitted fabric in this disclosure.

[0009] In this disclosure, preferred water absorption can be exemplified by a superior water absorption rate when moisture is applied to the fabric, simulating perspiration. Furthermore, as an example of suppressing stuffiness, one can exemplified by reducing insensible perspiration between the skin and clothing through hygroscopic properties.

[0010] The knitted fabric in this disclosure comprises at least cellulose fibers and polyester crimped yarn. Cellulose fibers have excellent hygroscopic properties, while polyester crimped fibers have excellent quick-drying and moisture-releasing properties. The use of crimped polyester fibers improves the water absorption and quick-drying properties of the knitted fabric. Furthermore, the knitted fabric has a first surface containing cellulose fibers and a second surface containing polyester crimped yarn comprising at least two types of polyester polymers. Here, the first surface and the second surface refer to one surface on the front and back of the knitted fabric, and the opposite surface. Which side is used as the front or back can be appropriately selected depending on the application.

[0011] In this disclosure, by using cellulose fibers as the first surface and polyester crimped yarn containing at least two types of polyester polymers as the second surface, it is possible to functionally separate hygroscopicity from quick-drying and moisture-releasing properties to obtain higher performance. Furthermore, it is preferable that the cellulose fibers have a larger diameter than the polyester crimped yarn, as this effect is even greater. The diameter can be determined by the method described in the examples.

[0012] Furthermore, it is preferable that the cellulose fibers on the first surface are primarily observed when the surface of the first surface is observed. Similarly, it is preferable that the polyester crimped yarn on the second surface is primarily observed when the surface of the second surface is observed. "Primarily observed" means that when the surface is observed under a microscope, the yarn is observed as the most abundant yarn in two dimensions. Furthermore, the area ratio of the cellulose fibers on the first surface and the polyester crimped yarn on the second surface is not particularly limited, but it is preferable that the cellulose fibers account for 50% or more of the fiber area constituting the first surface, and the polyester crimped yarn account for 50% or more of the fiber area constituting the second surface, more preferably 70% or more, and even more preferably 95% or more. The upper limit is 100%. Note that area % refers to the ratio of the area of ​​each fiber to the total fiber area per unit area observed, and specifically, the value obtained by the method described in the examples is used.

[0013] In this disclosure, the cellulose fibers are not particularly limited, but examples include cotton, regenerated fibers containing long filaments such as rayon and cupro, and plant fibers such as linen and hemp. Cotton is preferred among these. The blending ratio of cellulose fibers to the knitted fabric is 50 to 70% by mass. A cellulose blending ratio of 50% by mass or more, preferably 55% by mass or more, is excellent in terms of design by suppressing the sheen unique to synthetic fibers and also reduces stuffiness. A cellulose blending ratio of 70% by mass or less, preferably 65% ​​by mass or less, can improve the quick-drying performance of the material. The blending ratio can be determined by the method described in the examples below.

[0014] Furthermore, while not particularly limited, examples of polyester crimped yarn include composite fibers such as side-by-side composite fibers or eccentric core-sheath composite fibers, and false-twist crimped yarns with enhanced crimping due to pin false-twist processing. Examples of polyester include polyethylene terephthalate, polypropylene terephthalate, polybutylene terephthalate, and copolymers thereof. In the knitted fabric of this disclosure, since finer crimping tends to result in superior water absorption and quick-drying properties, it is preferable that the polyester crimped yarn contains at least two types of polyester polymers. By including at least two of these, water absorption and quick-drying properties can be enhanced due to structural differences. A preferred combination of the two polymers is polyethylene terephthalate or a copolymer thereof and polybutylene terephthalate or a copolymer thereof. For example, in the case of composite crimped yarn, a combination of yarns made from polyethylene terephthalate or a copolymer thereof and yarn made from polybutylene terephthalate or a copolymer thereof, mixed by blending, entanglement, etc., is preferred (wherein the yarn made from polyethylene terephthalate or a copolymer thereof and the yarn made from polybutylene terephthalate or a copolymer thereof, one may be a crimped yarn and the other a non-crimped yarn, or both may be crimped yarns). Among these, as the polyester crimped yarn in this disclosure, side-by-side type composite fibers or eccentric core sheath type composite fibers which easily yield fine crimp are preferred, side-by-side type composite fibers or eccentric core sheath type composite fibers of polyethylene terephthalate or a copolymer thereof and polybutylene terephthalate or a copolymer thereof are more preferred, and side-by-side type composite fibers or eccentric core sheath type composite fibers of polyethylene terephthalate and polybutylene terephthalate are even more preferred.

[0015] The knitted fabric of this disclosure is a plating structure. A plating structure, also known as a reinforcing yarn knit, is generally a structure in which two or more yarns are used to knit the fabric in two separate front and back sides. By using a plating structure, the cellulose fibers and polyester crimped yarn can be separated into a first surface and a second surface without creating a multi-layered knitted fabric. Here, it is preferable that the first surface is composed of a base yarn containing cellulose fibers and the second surface is composed of a reinforcing yarn containing polyester crimped yarn, as this can better demonstrate the effects of improved water absorption and reduced diffusible residual moisture content. Furthermore, unlike multi-layered knitted fabrics, a plating structure allows for a simpler and lighter design in addition to functionality. In other words, according to the configuration of this disclosure, even a plating structure, rather than a multi-layered knitted fabric, can be given excellent moisture absorption and release properties. For example, in Figure 1, if 1 is a cellulose fiber and 2 is a polyester crimped yarn, then the first surface is 3 and the second surface is 4. In the knitted fabric of this disclosure, by including at least the above-mentioned proportion of cellulose fibers and the above-mentioned polyester crimped yarn, and by having a plating structure for the knitted fabric, moisture absorption and release properties and water absorption and quick drying properties can be improved.

[0016] The method for producing the plating structure is not particularly limited, but for example, it can be obtained by simultaneously feeding and knitting cellulose fibers and polyester crimped yarn. In addition to cellulose fibers and polyester crimped yarn, elastic yarns such as polyurethane may also be fed simultaneously, which is one of the preferred embodiments in this disclosure.

[0017] Figure 1 is a schematic diagram showing a cross-section of a knitted fabric formed with a plating structure. In Figure 1, cellulose fibers 1 and polyester crimped yarn 2 are knitted together, and the appearance can be changed on each surface depending on the yarn tension during knitting, the diameter of the fibers, the shrinkage rate, etc. The surface viewed from above the paper in Figure 1 is the first surface 3, and the surface viewed from below the paper is the second surface 4. Varying the diameter of the fibers to cause them to be unevenly distributed on the first and second surfaces is a preferred manufacturing method in this disclosure.

[0018] The knitted fabric of this disclosure preferably has a water absorption test time (time by dropping method) of 3 seconds or less, and more preferably 2 seconds or less, after 10 washes. A time of 3 seconds or less shortens the time the moisture is in contact with the skin, resulting in a better feel against the skin. The lower limit is not particularly limited. Here, washing is the method specified in JIS L 1930 (2014) C4N, and "after 10 washes" means after repeating this method 10 times. Furthermore, the diffusible residual moisture content is preferably 30% or less, and more preferably 20% or less, after 1 hour following 10 washes. A value of 30% or less reduces the likelihood of the fabric sticking to the skin, resulting in better separation from the skin and a more refreshing feel. In this disclosure, by simultaneously satisfying the above ranges for both the dropping method and the diffusible residual moisture content, a more comfortable and refreshing feel against the skin can be obtained. The lower limit is not particularly limited, but is usually 1% or more. To shorten the time required by the drop method, examples of methods include increasing the proportion of cellulose fibers, making the crimp of the polyester crimp yarn finer, using crimp yarn containing at least two types of polyester polymers, and adding a wash-resistant water-absorbing agent during the dyeing process. To reduce the diffusible residual moisture content, examples of methods include increasing the proportion of polyester crimp yarn, making the crimp of the polyester crimp yarn finer, using crimp yarn containing at least two types of polyester polymers, and reducing the basis weight. The values ​​obtained by the drop method and the diffusible residual moisture content described above are those obtained by the method described in the examples.

[0019] Furthermore, the knitted fabrics described herein have a basis weight of 100 to 170 g / m². ２Preferably, the drape coefficient as defined in JIS L 1096 8.21.7 G method (2020) is 0.22 or higher. A drape coefficient of 0.22 or higher, preferably 0.25 or higher, and even more preferably 0.27 or higher is preferable in that it can improve the firmness of the fabric. There is no particular upper limit, but a value of 0.40 or lower is preferable in terms of flexibility. The polyester crimped yarn can create a firmness in the fabric, thereby improving the drape coefficient. In order to further increase the drape coefficient, in addition to increasing the fineness of the yarn or using a thicker yarn count, it is also preferable to increase the yarn density of the fabric, use a side-by-side type composite fiber or a core-sheath type composite fiber for the polyester crimped yarn, and select and use a yarn with a high stretch recovery rate (CR value) or boiling water shrinkage rate. In this disclosure, the preferred stretch recovery rate (CR value) of the polyester crimped yarn is 30% or higher, and the boiling water shrinkage rate is 4% or higher.

[0020] On the other hand, taking the above measures to increase the drape coefficient may reduce quick-drying properties. Therefore, it is preferable to keep the basis weight within the scope of this disclosure along with the drape coefficient. That is, in order to improve quick-drying performance, the basis weight should be 170 g / m². ２ Preferably, it is 160 g / m² ２ The following is preferable. Also, in terms of improving firmness, the weight should be 100 g / m. ２ Preferably, it should be 120 g / m² or more. ２ It is more preferable that the amount be greater than or equal to 130 g / m². ２ It is even more preferable that the above conditions are met. By using the drape coefficient and weight ranges within the scope of this disclosure, excellent firmness and texture can be obtained. The weight and drape coefficients described above are the values ​​obtained by the method described in the examples.

[0021] Furthermore, it is preferable that the stiffness / softness, as defined in JIS L 1096 (2020) Cantilever Method, be 15 to 40 mm. A stiffness / softness of 15 mm or more is preferable, and 20 mm or more is more preferable. A stiffness / softness of the above or higher is achieved by creating a firmness in the fabric using polyester crimped yarn. Also, a stiffness / softness of 40 mm or less is preferable, and 35 mm or less is more preferable. A stiffness / softness of below the above range provides a particularly flexible feel when used in clothing. To increase stiffness / softness, methods include increasing the fineness of the yarn, using a thicker yarn count, increasing the yarn density and basis weight of the fabric, and selecting yarns with high shrinkage recovery rate (CR value) and boiling water shrinkage rate. The stiffness / softness values ​​used above are those obtained by the method described in the examples.

[0022] The underwear of this disclosure is made using the knitted fabric of this disclosure. By having the first side of the knitted fabric of this disclosure face outwards and the second side face inwards, it is preferable that the underwear has excellent water absorption and quick-drying properties and can look like cotton underwear. Among underwear, underwear for use as a top, especially underwear for use as a men's top, is preferable because it looks like cotton and can be worn outside without an outer garment.

[0023] The present invention is not limited to the following embodiments. The performance in the embodiments was evaluated according to the following method.

[0024] (Calculation of Area Percentage) The knitted fabric was dyed with disperse dyes. Next, 10 random samples were taken from the disperse-dyed polyester crimped yarn and the undyed cellulose yarn using a microscope at 20 to 50x magnification, and a 5cm x 5cm area was observed on both sides. The area occupied by each fiber within the total area of ​​all fibers was determined, and the average was rounded to the nearest integer to calculate the area percentage. In cases where it was difficult to distinguish using the above method, such as with knitted fabrics dyed in dark colors, the determination was made based on appearance.

[0025] (Fiber diameter) The fiber diameter was measured in micrometers using a microscope at 50x magnification after randomly sampling 10 points. The obtained values ​​were rounded to the nearest integer by rounding to the first decimal place.

[0026] (Cellulose fiber content) The cellulose fiber content was measured in accordance with the blending ratio specified in JIS L 1030-2 (2010).

[0027] (Washing) Washing in this disclosure was carried out in accordance with the JIS L 1930 (2014) C4N method. Note that "after 10 washes" as described later refers to the time after repeating this method 10 times.

[0028] (Water Absorption) The water absorption was measured in accordance with JIS L 1907 (2010) 7.1.1 Dropping Method. Specifically, the "time by dropping method" in this invention refers to the time measured to the nearest second using a stopwatch, after dropping one drop of water from a burette onto a 200 mm x 200 mm test piece and allowing the water droplet to reach the surface of the test piece. The time from when the water droplet reaches the surface of the test piece until the specular reflection disappears and only wetness remains as the test piece absorbs the water droplet was measured in accordance with the JIS L 1907 (2010) 7.1.1 Dropping Method. A water absorption rate of less than 2 seconds was considered good water absorption, and a water absorption rate of 1 second was considered very good. The measurement was performed after 10 washes (HL10).

[0029] (Diffusible Residual Moisture Content) This was measured at the Kaken Test Center, a general incorporated foundation. Specifically, the mass (W) of a randomly selected 10 cm x 10 cm test piece was measured, 0.3 mL of water was dropped onto the test piece, and the mass (W0) was measured. The test piece was hung to dry under standard conditions (20°C, 65% RH), and the weight (Wt) was measured at predetermined intervals to calculate the residual moisture content (%) at each interval. From the obtained results, the residual moisture content (%) after 1 hour was calculated, and it was judged that it was fast-drying if it was 30% or less. The measurement was performed on a sample after 10 washes (HL10). ・Residual moisture content = {(Wt - W) / (W0 - W)} × 100.

[0030] (Drape coefficient) Measured in accordance with JIS L 1096 8.21.7 G method (2020).

[0031] (Rigidity / softness) Measured according to the cantilever method of JIS L 1096 (2020).

[0032] (Stiffness) In clothing, materials with stiffness maintain their shape and three-dimensionality. Conversely, materials without stiffness tend to conform to the body's lines when worn. Based on sensory evaluations by five experts, materials were rated as follows: 1 for no stiffness at all, 2 for some stiffness, 3 for moderate stiffness, 4 for slight stiffness, and 5 for great stiffness.

[0033] (Stuffiness) In clothing, materials that feel stuffy are often dry to the touch, while those that feel less stuffy feel moist. Based on sensory evaluations by five experts, materials were rated as follows: 1 for high stuffiness, 2 for slight stuffiness, 3 for moderate stuffiness, 4 for low stuffiness, and 5 for almost no stuffiness.

[0034] [Example 1] Using 60-count cotton yarn (diameter approximately 100-150 μm), a 55-decitex 72-filament side-by-side composite fiber (PBTPET) made of polyethylene terephthalate and polybutylene terephthalate (diameter approximately 60-80 μm), and a 22-decitex polyurethane yarn (diameter approximately 30-50 μm), a plating knitted fabric consisting of 61% cotton, 33% PBTPET, and 6% polyurethane was knitted according to a conventional method. Subsequently, scouring, peroxidation bleaching, dyeing with fluorescent dyes, and tenter drying were performed according to a conventional method to create a white fabric. After that, the fabric was immersed in a processing solution containing a water absorbent, softener, and antibacterial agent, then compressed in a mangle machine, and dried at 130-150°C to obtain the knitted fabric of Example 1. The basis weight was 150 g / m ２ The fabric was finished in the following manner. The area of ​​cellulose fibers accounted for approximately 90% or more of the area of ​​fibers constituting the first surface. Conversely, polyester fibers were present in a similar proportion on the second surface. The knitted fabric obtained in this manner had superior firmness compared to the knitted fabrics of Comparative Examples 1 to 3, which did not contain polyester crimped yarn, and had superior quick-drying properties compared to the knitted fabric of Comparative Example 2, which had the same weight. Furthermore, it had superior water absorption and breathability compared to Comparative Example 3, which was not a plating structure. The evaluation results are shown in Table 1.

The area of the cellulose-based fibers with respect to the area of the fibers constituting the first surface was about 90% or more. Conversely, polyester fibers were present in a similar amount on the second surface. The knitted fabric obtained in this way was slightly inferior in quick-drying property compared to Example 1, but excellent water absorption, quick-drying property, and stuffiness results were obtained as in Example 1. The evaluation results are shown in Table 1.

The area of the cellulose-based fibers with respect to the area of the fibers constituting the first surface was about 95% or more. Conversely, polyester fibers were present in a similar amount on the second surface. Although it was inferior in stiffness and quick-drying property compared to Example 2 which is a side-by-side type composite fiber (PBTPET), excellent water absorption was obtained. The evaluation results are shown in Table 1.

Following a conventional method, it was dyed using disperse dyes and reactive dyes to achieve black color, then treated with a cotton fixative and tenter-dried. The resulting black fabric was subjected to the same finishing process as in Example 1 to obtain the knit fabric of Example 4. The basis weight was 200 g / m ２ The fabric was finished using the following method. The area of ​​cellulose fibers accounted for over 90% of the total fiber area of ​​the first surface. Conversely, polyester fibers were present in a similar proportion on the second surface. The resulting knitted fabric had a basis weight of 200 g / m². ２ However, 150 g / m ２ Excellent breathability was achieved. The evaluation results are shown in Table 1.

Subsequently, scouring, peroxidation bleaching, dyeing with fluorescent dyes, and tenter drying were performed according to a conventional method to create a white fabric. After that, the fabric was immersed in a processing solution containing a water absorbent, softener, and antibacterial agent, then compressed in a mangle machine, and dried at 130-150°C to obtain the knit fabric of Comparative Example 1. The basis weight was 175 g / m ２ The surface was finished using the following method.

In the fabric subjected to dyeing and finishing treatment in the same manner as in Comparative Example 1, the basis weight was adjusted to 150 g / m ２ by stretching in the width direction. The area of the cellulose-based fibers with respect to the area of the fibers constituting the first surface was about 95% or more. Conversely, polyester fibers were present in a similar amount on the second surface. The obtained knitted fabric was inferior in stiffness compared to the knitted fabrics of Examples 1 and 2 having the same basis weight. The evaluation results are shown in Table 1.
