For example, it may be a fixed connection, a detachable connection, or an integral connection, a mechanical connection, an electrical connection, a direct connection, or a connection through an intermediate member, or a connection inside two components. Those skilled in the art can understand the meaning of the above terms according to the situation.

[0024] [Moisture-absorbing, heat-generating, heat-retaining fabric] The moisture-absorbing, heat-generating, and heat-retaining fabric of the first specific embodiment of the present invention includes a heat-generating layer 1 and a napped layer 2, as shown in Figure 1.

[0025] The heat-generating layer 1 has a reinforcing yarn structure, preferably a full-loop reinforcing yarn structure with plain knit as the base structure. A schematic diagram of the reinforcing yarn structure is shown in Figure 2.

[0026] The heat-generating layer 1 includes a ground yarn layer 11 and a reinforcing yarn layer 12.

[0027] The ground yarn layer 11 contains a first yarn 111, and the first yarn 111 contains a moisture-absorbing, heat-generating yarn.

[0028] The moisture-absorbing, heat-generating yarn includes, for example, one or more types of yarn (e.g., blended yarn) selected from regenerated cellulose fibers, cotton, wool, polyester fibers, polyamide fibers, viscose fibers, and polyacrylonitrile fibers. Both the yarn and the blended yarn are commercially available and readily obtainable.

[0029] The thickness of the first thread 111 is, for example, 20-300D (e.g., 20D, 40D, 60D, 80D, 100D, 150D, 200D, 250D, or 300D), or 10-100S (e.g., 10S, 20S, 40S, 45S, 50S, 60S, 80S, or 100S).

[0030] The supplementary yarn layer 12 includes a second yarn 121, and the second yarn 121 includes an elastic yarn.

[0031] The elastic yarn includes, for example, at least one yarn or two or more yarns (e.g., blended yarn) selected from polyurethane elastic fiber yarn, polyolefin elastic fiber, polyester elastic fiber, and polyamide elastic fiber. Both the yarn and the blended yarn are commercially available and readily obtainable.

[0032] The thickness of the second thread 121 is, for example, 5-60D (e.g., 5D, 10D, 15D, 20D, 30D, 40D, 50D, or 60D).

[0033] The napped layer 2 contains a third yarn 211, and the third yarn 211 contains natural fibers and / or regenerated cellulose fibers.

[0034] The aforementioned natural fibers include, for example, at least one yarn or two or more yarns (e.g., blended yarns) selected from cotton, linen, wool, and silk. Both the yarns and blended yarns are commercially available and readily obtainable.

[0035] The regenerated cellulose fiber includes, for example, at least one yarn or two or more yarns (e.g., blended yarns) selected from rayon, cupro, lysel fibers, and modal fibers. Both the yarns and blended yarns are commercially available and readily obtainable.

[0036] The third yarn 211 is, for example, a low-twist yarn or a bulky yarn.

[0037] The thickness of the third thread 211 is, for example, 20-300D (e.g., 20D, 40D, 60D, 80D, 100D, 120D, 150D, 200D, 250D, 300D) or 10-100S (e.g., 10S, 20S, 30S, 40S, 50S, 55S, 60S, 70S, 80S, 90S, or 100S).

[0038] The napped layer 2 is, for example, a loop structure or a plain knit structure. Among the napped layer 2, the loop structure is preferred because it has excellent heat retention properties. A schematic diagram of the loop structure is shown in Figure 3.

[0039] An air layer containing a large amount of static air is formed between the loop tissue structures of the raised layer 2. Since air has a low thermal conductivity, the air layer has excellent heat preservation function, can effectively block the dissipation of the heat of the human body to the outside, and can reduce the intrusion of cold outside air. Furthermore, since the loop tissue structure has a three-dimensional protrusion structure, the specific surface area of the fabric is greatly increased, and when it comes into contact with moisture (e.g., sweat), the moisture can be adsorbed rapidly. Also, the voids between the loop tissue structure and the fabric substrate accelerate the diffusion and evaporation of water vapor and suppress the retention of moisture, so the moisture absorption and heat generation properties and quick drying property of the fabric can be enhanced.

[0040] The length of the hairs of the raised layer 2 is, for example, 0.3 to 10 mm (e.g., 0.3 mm, 0.5 mm, 1 mm, 2 mm, 2.5 mm, 3 mm, 4 mm, 6 mm, 8 mm, or 10 mm).

[0041] The density of the hairs of the raised layer 2 is, for example, 500 to 2000 hairs / cm 2 (e.g., 500 hairs / cm 2 、600 hairs / cm 2 、650 hairs / cm 2 、700 hairs / cm 2 、900 hairs / cm 2 、1100 hairs / cm 2 、1300 hairs / cm 2 、1500 hairs / cm 2 、1700 hairs / cm 2 、1900 hairs / cm 2 、or 2000 hairs / cm 2 )

[0042] The heat generating layer 1 and the raised layer 2 are connected by a joining thread. The joining thread is, for example, the third thread 211. Examples of the third thread 211 used for the joining thread are the same as those of the third thread 211 included in the raised layer 2.

[0043] The moisture absorption, heat generation and heat preservation fabric has high-efficiency moisture absorption and heat generation characteristics and continuous heat storage and heat preservation properties, and at the same time is soft and comfortable, and excellent in elasticity and quick drying property.

[0044] There are no particular limitations on the method for manufacturing the moisture-absorbing, heat-generating, and heat-retaining fabric. For example, it can be manufactured by knitting the fabric according to a desired structural composition and by performing a napping treatment on the napped layer. In the napping treatment step, it is preferable to treat the napped layer so that the length and density of the fibers are within a predetermined range.

[0045] [Textiles] The textile of this invention includes at least the above-mentioned moisture-absorbing, heat-generating, and heat-retaining fabric.

[0046] Examples of the aforementioned textiles include thermal underwear, outdoor sportswear, children's clothing, and household textile products. [Examples]

[0047] To more clearly demonstrate the technical effects of the moisture-absorbing, heat-generating, and heat-retaining fabric provided by this invention, the technical solutions will be explained below with specific examples and data.

[0048] Example 1 A moisture-absorbing, heat-generating, and heat-retaining fabric was manufactured, consisting of a heat-generating layer 1 and a napped layer 2 joined together with a bonding yarn. The heat-generating layer 1 has a plain knit base structure with a full loop supplement yarn structure, and includes a base yarn layer 11 and a supplement yarn layer 12. A schematic diagram of the structure of the moisture-absorbing, heat-generating, and heat-retaining fabric is shown in Figure 1, and a triangular arrangement diagram of the woven structure of the moisture-absorbing, heat-generating, and heat-retaining fabric is shown in Figure 4.

[0049] A polyacrylonitrile fiber / viscose blend yarn with a thickness of 50S was used as the first yarn 111 that constitutes the ground yarn layer 11.

[0050] A 40D polyurethane fiber was used as the second thread 121 that constitutes the reinforcing thread layer 12.

[0051] Cotton with a thickness of 50S was used as the third yarn 211 that constitutes the napped layer 2. Then, a fabric with a loop structure was knitted using this third yarn 211. Next, the resulting fabric was subjected to a napping treatment to make the length of the napped layer 2 fibers 2.5 mm and the density of the fibers 700 fibers / cm. 2 This created the second napped layer.

[0052] Cotton with a thickness of 50S was used as the joining thread.

[0053] Example 2 A moisture-absorbing, heat-generating, and heat-retaining fabric was obtained in the same manner as in Example 1, except for the following changes. A wool / cotton blend yarn with a thickness of 45S was used as the first yarn 111 that constitutes the ground yarn layer 11. The third yarn 211 that makes up the napped layer 2 is made of cotton with a thickness of 55S, with a pile length of 2mm and a pile density of 650 fibers / cm. 2 The napped finish was applied. Cotton with a thickness of 55s was used as the joining thread.

[0054] Example 3 A moisture-absorbing, heat-generating, and heat-retaining fabric was obtained in the same manner as in Example 1, except that the structure of the napped layer 2 was changed from a loop structure to a plain knit structure.

[0055] Comparative Example 1 A moisture-absorbing, heat-generating, and heat-retaining fabric was obtained in the same manner as in Example 1, except that the napped layer 2 was not subjected to a napping treatment.

[0056] The moisture-absorbing, heat-generating, and heat-retaining fabrics obtained in the examples and comparative examples were subjected to the following performance tests (1) to (3). The results are shown in Table 1. Performance testing (1) Heat retention: The heat retention rate was measured according to the constant temperature method of JIS L 1096A. (2) Moisture-absorbing heat generation: The moisture-absorbing heat generation temperature was measured in accordance with ISO 18782. (3) Moisture absorption: The moisture absorption rate of the fabric was measured according to the BOKEN method BQE A034.

[0057] [Table 1]

[0058] As can be seen from Table 1, the fabrics of Examples 1 to 3 have higher heat retention, moisture-absorbing heat generation temperature, and moisture absorption rate compared to the non-brushed fabric of Comparative Example 1.
