Description

Technical Field

[0001] The present invention relates to composite fabrics and textiles, and particularly to composite fabrics and textiles including a fabric structure layer composed of cotton fibers and nylon fibers.

Background Art

[0002] A composite fabric refers to a fabric woven using fibers of a plurality of different materials. For example, there is a heat-insulating fabric structure presented in Patent Document 1. The one described in the above Patent Document 1 is a double-sided fabric formed by knitting or plain-weaving cotton fibers and polyester fibers, with the upper surface being a cotton fiber surface and the bottom surface being a polyester fiber surface. In clothing production, by facing the cotton fiber surface outward to contact with air and the polyester fiber surface toward the body side, a microclimate is formed between the double-sided fabric and the body. Due to the natural touch and hydrophilicity of cotton fibers, and the breathability, hydrophobicity, and lightness of polyester fibers, this heat-insulating fabric structure has natural touch, heat insulation, freshness, breathability, and lightness.

[0003] However, in the one described in Patent Document 1, the surface facing the body side uses polyester fibers and has no water absorption property. Conversely, when sweating on the body, it gets wet and is uncomfortable. Also, the used polyester fibers cannot provide any other functionality in addition to the above-mentioned properties. When wearing clothes made of the heat-insulating fabric structure described in the above Patent Document 1, the temperature cannot be rapidly lowered. Therefore, it is not suitable for use in a 25°C air-conditioned environment, for example. Moreover, in an environment such as a -40°C freezer with a lower temperature, the heat insulation effect does not reach the blood flow velocity and blood flow volume of the tiny blood vessels on the skin surface, causing frostbite.

[0004] Patent Document 2 presents a composite fabric and textile that uses functional nylon fibers, such as nylon fibers containing a collagen structure, and nylon fibers containing far-infrared radiating materials simultaneously to give the composite fabric and textile far-infrared functionality, as well as moisturizing and cooling effects, thereby reducing itching of the user's skin. However, all of the materials described in Patent Document 2 provide functionality for composite fabrics and textiles using functional nylon fibers, and therefore do not take into account natural feel, comfort, or hydrophilicity (sweat absorption).

[0006] The objective of this invention is to provide fabrics and textiles that possess a natural feel, comfort, and sweat absorption, while also being suitable for use in air-conditioned environments and freezers. [Means for solving the problem]

[0007] A composite fabric according to one embodiment of the present invention includes a woven structure layer, wherein the woven structure layer is a woven structure layer or knitted structure layer composed of a plurality of first yarns and a plurality of second yarns, wherein the first yarns are cotton fiber yarns, and the second yarns are nylon fibers containing pebble particles or nylon fibers containing far-infrared radiating material, wherein the woven structure layer is formed by interweaving the first yarns in the warp direction and the second yarns in the weft direction, or by interweaving the second yarns in the warp direction and the first yarns in the weft direction. The knitted fabric structure layer is formed by a plain weave, twill weave, or satin weave structure, and the knitted fabric structure layer includes a plurality of interleaved first stitches and a plurality of interleaved second stitches, wherein the plurality of first stitches are made of a plurality of first yarns, the plurality of second stitches are made of a plurality of second yarns, and at least some of the plurality of first stitches and at least some of the plurality of second stitches are interleaved, thereby forming the knitted fabric structure layer.

[0008] The aforementioned knitted fabric structure layer may be a single-sided knitted fabric structure layer or a double-sided knitted fabric structure layer.

[0009] The aforementioned single-sided knitted fabric layer may be composed of a rib structure, a jacquard structure, a pique structure, or a mesh structure.

Advantages of the Invention

[0017] The composite fabric and textile of the present invention are made by knitting and weaving with functional nylon fibers and cotton fiber yarns.

By combining nylon fibers containing jade particles and cotton fiber yarns for knitting and weaving, even when the user is in a cold room, the temperature can be rapidly reduced without the user getting hypothermia. The nylon fibers containing far-infrared radiation materials can increase the blood flow rate and blood volume of the tiny blood vessels on the skin surface of the user even when the user is in a freezer environment, preventing frostbite.

Mode for Carrying Out the Invention

[0019] Hereinafter, embodiments of the present invention will be described in detail based on the drawings. Needless to say, the present invention is not limited to the embodiments described below.

[0020] As shown in FIGS. 1A and 1B, the composite fabric of the present invention includes a fabric structure layer 1. The fabric structure layer 1 is a fabric structure layer 1' or a knitted fabric structure layer 1" (see FIGS. 2A and 2B) composed of a plurality of first yarns 11 and a plurality of second yarns 21. The first yarn 11 is a cotton fiber yarn 111, and the second yarn 21 is a nylon fiber 211 containing jade particles or a nylon fiber 211' containing a far-infrared radiation material.

[0021] <Fabric structure layer 1'> The fabric structure layer 1' is formed by interweaving the first yarn 11 in the warp direction and the second yarn 21 in the weft direction, or by interweaving the second yarn 21 in the warp direction and the first yarn 11 in the weft direction, thereby forming a fabric structure layer 1' composed of a plain weave, a twill weave or a satin or sateen weave. As shown in FIGS. 1A and 1B, in the fabric structure layer 1' of the plain weave, the first yarn 11 in the warp direction and the second yarn 21 in the weft direction are interwoven, and each adjacent first yarn 11 alternately intersects up and down, and each adjacent second yarn 21 also alternately intersects up and down.

[0022] <Knitted fabric structure layer 1"> As shown in Figures 2A and 2B, the knitted fabric structure layer 1" is either a single-sided knitted fabric structure layer or a double-sided knitted fabric structure layer. Taking the double-sided knitted fabric structure layer as an example, the double-sided knitted fabric structure layer includes a plurality of interlocked first stitches 10 and a plurality of interlocked second stitches 20, and at least some of the plurality of first stitches 10 and at least some of the plurality of second stitches 20 are interlocked, forming a double-sided knitted fabric structure layer composed of an interlock structure, a double-sided jacquard structure, a double-sided pile structure, or a double-sided pique structure.

[0023] Figures 2A and 2B show an interlock structure as an example. If we consider the top to bottom as the first, second, and third rows respectively, the four first stitches 10 in the first row are connected to each other to form a row, and the same is true for the second and third rows, where the four first stitches 10 are connected to each other to form rows. However, this is omitted in Figures 2A and 2B. The first and second rows each have four second stitches 20 connected to each other to form a row, and the four second stitches 20 of the first row and the four second stitches 20 of the second row are passed through each other. Similarly, the four first stitches 10 of the second row and the four first stitches 10 of the third row are passed through each other, but this is omitted in Figures 2A and 2B. Furthermore, in Figures 2A and 2B, the rows are labeled 1st, 2nd, 3rd, and 4th from right to left, respectively. Taking the 1st row as an example, the 1st stitch 10 and the 2nd stitch 20 are passed through each other, and the same is true for the 2nd, 3rd, and 4th rows, where the 1st stitch 10 and the 2nd stitch 20 are passed through each other. In this case, the 1st stitch 10 is composed of multiple strands of 1st yarn 11, and the 2nd stitch 20 is composed of multiple strands of 2nd yarn 21. For example, in the case of a flat knitting machine, the 1st yarn 11 and the 2nd yarn 21 are supplied by a dial needle and a cylinder needle, respectively.

[0024] <First Yarn and Second Yarn> The first yarn 11 is a cotton fiber yarn 111, and its number ranges from 40 to 80 strands. The second yarn 21 has a denier count of 40 to 300 denier and is composed of single fibers of nylon fiber 211 containing 38 to 288 jade particles. For example, the nylon fiber 211 containing jade particles produced by a certain biotechnology company in northern Taiwan is made by using Hualien Fengtian jade from Taiwan, which is polished into a powder with a particle size of 100 nm to 2000 nm, mixed with nylon, and then spun (see Taiwan Patent No. I350872).

[0025] Alternatively, the second yarn 21 is a nylon fiber 211' containing far-infrared radiating material. The nylon fiber 211' containing far-infrared radiating material is a nylon fiber containing germanium metal particles, a nylon fiber containing graphene particles, or a nylon fiber containing bamboo charcoal particles. The second yarn 21 has a denier count ranging from 40 to 300 denier and is composed of single nylon fibers 211' containing 38 to 288 far-infrared radiating materials. The nylon fiber 211' containing far-infrared radiating material may be, for example, a nylon fiber with a germanium content of 2.0 wt% to 2.5 wt% (by weight) sold by a certain company in Taiwan. Since this is made by mixing germanium particles with nylon and spinning it, it is resistant to washing and possesses far-infrared functionality.

[0026] <Composite Fabrics and Textiles> For example, the first yarn 11 and the second yarn 21 are supplied from the dial needle and cylinder needle of a flat knitting machine, respectively, with a weight range of 180 g / m². 2 From 400g / m 2 When a controlled double-knit structure layer is woven between these layers, a composite fabric with comfort and functionality is obtained. Textile 100 is produced using this comfortable and functional composite fabric by known textile manufacturing processes. Textile 100 can be used for inner shirts, outerwear, inner pants, or other general clothing, bedding, and decorative items, with an inner shirt being shown as an example in Figure 3. Of these, the first yarn 11 accounts for 60% to 90% of the weight of the double-knitted fabric structure layer, and the second yarn 21 accounts for 10% to 40% of the weight of the double-knitted fabric structure layer. The proportions of the first yarn 11 and the second yarn 21 are adjusted according to the intended use of the textile and the desired functional effects. [Examples]

[0027] In Example 1, the composite fabric has an interlock structure in the double-knitted structure layer, the first yarn consists of 60 cotton fibers, and the second yarn consists of 48 single fibers of nylon fibers containing germanium metal particles, with a denier count of 70 denier. Cotton fibers account for 70% of the weight of the double-knitted fabric structure layer, and nylon fibers containing germanium metal particles account for 30% of the weight of the double-knitted fabric structure layer. The weight of the double-knitted fabric structure layer is 300 g / m². 2 That is the case.

[0028] <Tests of average far-infrared emissivity, blood flow rate, blood flow velocity, skin surface temperature, and surface temperature under specific heat sources and conditions> The composite fabric according to Example 1 was sent to TTRI (Textile Research Institute) for testing of the average far-infrared emissivity, blood flow rate, blood flow velocity, skin surface temperature, and surface temperature under specific heat sources and conditions. The test methods and test results are shown in Table 1.

[0029] [Table 1]

[0030] As shown in Table 1, the average far-infrared emissivity of the composite fabric according to Example 1 reached 0.83. Generally, a test result of 0.8 or higher using the FTTS-FA-010 method indicates the presence of far-infrared effects, thus demonstrating that the fabric possesses far-infrared properties. Furthermore, the blood flow rate measured before wearing the composite fabric according to Example 1 was 14.1, and the measured value 10 minutes after wearing it was 16.3, representing a difference of 15.6%. The blood flow velocity measured before wearing the composite fabric according to Example 1 was 21.7, and the measured value 10 minutes after wearing Example 1 was 25.6, representing a difference of 18.0%. Therefore, both the blood flow rate and blood flow velocity measurements indicate that the blood flow rate and blood flow velocity 10 minutes after wearing the composite fabric according to Example 1 are at least 1.179 times higher than before wearing it. Furthermore, the skin surface temperature increased from 31.7°C before use to 34.2°C after use, an increase of 2.5°C. Under specific heat sources and conditions, the surface temperature increased from 20.04°C before irradiation to 28.80°C after use, an increase of 8.76°C. Therefore, it has been proven that the composite fabric according to Example 1 has the effect of far-infrared radiation, and when the user is in a freezer environment, it can increase the blood flow velocity, blood flow rate, and skin surface temperature of the tiny blood vessels on the skin surface, preventing frostbite, and that the temperature can be quickly restored when the user leaves the freezer and returns to normal room temperature or is heated with a heat source. [Examples]

[0031] In Example 2, the composite fabric has an interlock structure in the double-knitted structure layer, the first yarn consists of 60 cotton fibers, and the second yarn consists of 48 single fibers of nylon fibers containing pebble particles, with a denier count of 70 denier. Cotton fibers account for 70% of the weight of the double-knitted fabric structure layer, and nylon fibers containing pebble particles account for 30% of the weight of the double-knitted fabric structure layer. The weight of the double-knitted fabric structure layer is 300 g / m². 2 That is the case.

[0032] <Tests of instant contact cooling sensation and skin surface temperature> The composite fabric according to Example 2 was sent to TTRI (Textile Research Institute) for testing of instantaneous contact cooling and skin surface temperature. The test methods and test results are shown in Table 2.

[0033] [Table 2]

[0034] The comparative example features an interlock structure in a double-knitted layer, where both the first and second yarns are ordinary nylon fibers with no special functionality, a denier count of 70, and composed of 48 single fibers.

[0035] As shown in Table 2, the instantaneous contact cooling Q-max value of the composite fabric according to Example 2 is 0.152 W / cm². 2 The test result using the FTTS-FA-019-2022 method is generally 0.130 W / cm². 2 If the above is achieved, it can be considered to have a cooling sensation upon contact. In addition, the skin surface temperature was 33.1°C before use and 31.2°C after use, a decrease of 1.9°C. On the other hand, the comparative example showed a temperature of 33.0°C before use and 32.5°C after use, a decrease of only 0.5°C. Therefore, the composite fabric according to Example 2 has been proven to have a cooling effect, and when a user enters an air-conditioned room from an extremely hot external environment, it can rapidly lower the skin surface temperature, resulting in a cooling sensation and energy-saving effect.

[0036] <Evaluation of natural feel, comfort, and prolonged stay in an air-conditioned room> For Examples 1 and 2 and the Comparative Example, multiple inner shirts were produced for each example, designated as Application Example 1, Application Example 2, and Application Comparative Example. Five subjects aged 20-40 years wore these shirts directly against their skin under ambient temperature and humidity conditions of 25±2°C and 65±4%RH, and described the natural tactile sensation during wear. The average results are shown in Table 3. In Application Example 2 and Application Comparison Example, participants ran on a treadmill for 40 minutes, observing whether sweat remained on the inner shirt or body, or dripped onto the equipment, and judging comfort based on whether or not they felt stuffy. The average results are shown in Table 3. After wearing the inner shirts described in Application Example 2 and Application Comparative Example, participants spent one hour outdoors at 33°C, respectively. Then, they entered air-conditioned rooms at 25±2°C and 65±4%RH, and their body's sensation of coldness and warmth was evaluated after three hours.

[0037] [Table 3]

[0038] As shown in Table 3, both Application Examples 1 and 2 contain 70% cotton fiber yarn by weight, resulting in a good feel and being judged as acceptable. On the other hand, the Comparative Application Example does not contain cotton fiber yarn, resulting in a rough feel and being judged as unacceptable. Regarding comfort, in Application Example 2, the cotton fiber yarn accounts for 70% by weight, and it was observed that after 40 minutes of running on a treadmill, sweat was absorbed and remained on the shirt, not falling onto the equipment. Furthermore, since the nylon fiber containing the pebble particles in Application Example 2 accounts for 30% by weight, the body heat generated after exercise is quickly dissipated to the outside, preventing stuffiness and resulting in a comfortable and satisfactory result. On the other hand, the Comparative Application Example is woven only from ordinary nylon fiber with no functional properties, and contains neither cotton fiber yarn nor the aforementioned nylon fiber containing pebble particles. As a result, sweat is not absorbed by the shirt and falls onto the equipment, and the body heat generated after exercise is not quickly dissipated to the outside, causing stuffiness and discomfort, and resulting in a failure to meet the criteria. When staying in an air-conditioned room for an extended period, Application Example 2, containing 70% cotton fiber by weight, was judged to be comfortable and acceptable after 3 hours in an air-conditioned room at 25±2℃ and 65±4%RH because the cotton fiber was able to maintain body temperature. On the other hand, Application Example 2 was judged to be unacceptable because it was knitted using only general nylon fibers with no functional properties and lacked any cotton fiber to maintain body temperature, causing body temperature to continuously decrease and making the wearer feel cold.

[0039] The garment in Application Example 2 offers comfort and practicality when worn. The fabric is gentle on the skin, soft to the touch, elastic, lightweight, and highly breathable, preventing stuffiness. Even in air-conditioned rooms, its excellent breathability and slight heat retention allow for a comfortable temperature, preventing feelings of cold even with strong air conditioning. The stable perceived temperature is a major advantage.

[0040] The above is a description of embodiments of the present invention, and these do not limit the present invention. Any changes or modifications that do not depart from the scope of the utility model registration claims are included within the scope of the rights of the present invention. [Explanation of Symbols]
