Description

Detailed Description of the Invention [Industrial Application Field] The present invention relates to fabrics using conventional general-purpose filament yarns and/or spun yarns made by general-purpose machines to remove moisture (sweat) from the skin of a sweat-prone wearer. The present invention relates to a moisture transfer fabric that eliminates the wet feeling caused by the fabric in contact with the skin by transferring the moisture to the surface of the fabric or into the interior of the fabric when absorbed.

[Prior Art] Various technical means have been proposed in the past in order to reduce the discomfort of getting wet when knitted fabrics absorb sweat. For example, in the invention of JP-A-52-25158, one side or the inner layer of the fabric is made of fine fibers of 0.7 d or less, and one side or both outer layers of the fabric are made of thick fibers of 1 d or more, There is a description of a water-absorbent fabric that is composed of a fiber/fineness fiber ratio of 4 or more and whose fiber surface is made hydrophilic, and in Japanese Utility Model Publication No. 12290/1983, the front side of the knitted fabric is made of hydrophobic fibers, In a three-layer knitted fabric in which the back side is made up of hydrophobic fibers and hydrophilic fibers, and the middle layer is made of hydrophilic fibers, the part made up of the hydrophilic fibers on the back side is higher than the part made up of the hydrophobic fibers. (There is a description of a knitted fabric with a three-layer structure in which the hydrophilic fibers on the back side are connected to the hydrophilic fibers in the middle layer, and JP-A-2-20742 discloses a fabric made of filament yarns of synthetic fibers. A knitted fabric having an uneven structure surface on one side and a water-absorbing layer on the opposite side of the uneven structure surface, the layer having the uneven structure and the water-absorbing layer being connected by a water-conducting portion made of water-conducting fibers. and an air-containing layer made of intercalated yarn is interposed between the uneven structure surface layer and the water absorption layer, and the single yarn denier of the yarn constituting the air-containing layer and the single yarn of the yarn constituting the air intake layer are This invention relates to a water-absorbing and heat-retaining knitted fabric whose denier satisfies D4/D5≧25, and at the same time, the single yarn denier of the yarns constituting each layer satisfies either of the following formulas.

Here D, >DI≧D2≧D3≧D5 ・・・・・・
・・(1) D4>D,>D2≧D3≧D5 ・・
・・・・・・・・・(2) However, D,...Single yarn denier D2 of the yarn forming the convex portions on the uneven surface...Single yarn denier D3 of the yarn forming the concave portions on the uneven surface. ...Single thread denier of water-conducting fiber D4...Single thread denier of inserted yarn d,...Single thread denier of yarn forming the water-absorbing layer As mentioned above, inventions and ideas related to water-absorbing or water-absorbing and heat-retaining fabrics There are many (exist).

[Problem to be Solved by the Invention 1] In view of the above, it is possible to easily produce moisture-transferable fabric at low cost using conventional machinery and equipment using filament yarns and/or spun yarns of versatile synthetic fibers or natural fibers. Considering the conventionally known techniques mentioned above from the viewpoint of the above, the invention of JP-A-52-25186 uses fine denier fibers with a water-absorbing fabric of 0.7 d or less and large fibers with a denier four times or more larger than that. In addition, the fiber surface is made hydrophilic.

According to the specification of the above-mentioned invention, knitted and woven fabrics using such fine fibers are complicated to manufacture, and there is a problem in that they cannot be expected to have very high heat retention properties despite being expensive. In addition, the device proposed in Japanese Utility Model Application Publication No. 58-12290 uses a three-layer knitted fabric consisting of hydrophobic fibers on the front side, hydrophobic fibers and hydrophilic fibers on the back side, and hydrophilic fibers in the middle layer. The structure of the knitted fabric is complicated because the part made of hydrophobic fibers rises higher than the part made of hydrophobic fibers, and the hydrophilic fibers on the back side are connected to the hydrophilic part of the middle layer. Although it takes time and effort to manufacture, its water absorption and heat retention properties are not sufficient.

Furthermore, since the invention of JP-A-2-20742 uses a combination of various denier yarns, the structure of the knitted fabric is complicated, and therefore, there is a problem that manufacturing is expensive.

The present invention provides a versatile synthetic fiber filament yarn and/or
Alternatively, it is an object of the present invention to easily produce moisture-transferable fabrics at low cost using spun yarn, other natural fibers, or artificial fibers.

[Means for Solving the Problems 1] In order to achieve the above object, the first aspect of the present invention is to use filament yarns of synthetic fibers and/or bulky yarns with a sparse density of spun yarns, such as crimped yarns and filament yarns of synthetic fibers. and/or fabrics that are composed of spun yarns and/or high-density parts made of natural fibers or artificial fibers, and related to moisture-transferring fabrics in which moisture absorbed by the fabric migrates from a surface with a loose density to a surface with a high density. The second is a bulky yarn with a low density of synthetic fiber filament yarn, such as a crimped yarn, as the front or back surface,
The fabric is composed of the bulky yarn and filament yarns and/or spun yarns of synthetic fibers and/or high-density internal fibers of natural fibers and artificial fibers, and moisture absorbed into the fabric flows from the front or back side into the fabric. The present invention provides a moisture transfer fabric that transfers.

The fibers used in the present invention may be one or more filament yarns and/or spun yarns of synthetic fibers such as polyester, nylon, polyamide, and polyurethane on both the dense and sparse sides, and in particular polyester fibers. Synthetic fibers are preferred. The yarn used in the dense portions may be of any type, and may be natural fibers such as cotton, wool, silk, linen, or spun or filament yarns of synthetic fibers. The yarn used in the sparse portions may be filament yarn or spun yarn of crimped synthetic fibers, or may be crimped by post-processing.

Regarding the thickness of the thread used, any conventional thread thickness may be used. The less dense bulky side is used on the back side, and the higher density one is used on the front side with highly twisted yarn. When sewing on underwear, the less dense side should be used as the skin measurement, and the richer side should be used as the surface.

Furthermore, it is also possible to use pile-like bulky yarns on both the front and back sides, and create a fabric using high-density yarns inside.

[For use] When crimpable synthetic fiber filament yarn is boiled, it becomes crimped and becomes bulky as shown in the lighted part in Figure 1.One part (B) is left as it is in Figure 1, and the other part is ( If a drop of water is applied to point (A) on the border of the twisted state as shown in Fig. 2, the arrow (-) will be drawn.
), the water spreads toward C, but hardly spreads toward (B). This phenomenon indicates that the capillary phenomenon is greater in areas where the fiber density is denser than in areas where the fiber density is sparse. The present invention is based on this principle. That is, when fabrics are manufactured using the above-described principle, moisture can be transferred from one side to the other, or from the front and back surfaces to the inner surface, even with one type of 100% synthetic fiber.

The structural diagram of this fabric is shown in Figures 3 (a) and (b).

When you wear this fabric with the less dense side (1) facing your skin,
As soon as the sweat is absorbed into the fabric, it is absorbed into the dense areas (
2) Move to. Therefore, the skin surface is no longer wet and can maintain a refreshing feel. Of course, it is also possible to use two or more types of yarn to make the fabric more comfortable to wear, and to control the fabric weight. In addition, the threads used in dense areas are not only synthetic fibers, but also cotton, wool,
Natural fibers such as silk and hemp, and artificial fibers such as human silk and cotton wool can also be used.

[Example] Next, the present invention will be explained by examples.

Example 1 The fleece structure of a circular knitting machine was knitted using 100% polyester, nylon, or acrylic filament yarn, and the fabric was knitted with 100% filament yarn of polyester, nylon, or acrylic.
Knitted fabric with a structure of The structure of this leek dough is shown in Figure 4. Lay-in (3) in Figure 4
Because the yarn does not form loops, if it is sufficiently crimped as shown in Figure 1 (Bj), the density becomes small and bulky, whereas tie-in (4) and knit-in (4)' are continuous loops. After wetting this dense knitted fabric with water, when we squeezed it gently with our hands, the (3) side didn't feel wet at all, whereas the 4) side felt very wet. . The same is true for sweat. Although filament yarn was used in the above example, spun yarn is also used. It is suitable as a fabric for sports clothing.

Example 2 The bracket pile structure of a circular knitting machine was knitted with polyester filament yarn to form piles (5) and cotton yarn to form stitches (6).

A structural diagram of this knit fabric is shown in Figure 5.

When the pile portion (5) of the polyester filament yarn is sufficiently crimped, it becomes bulky. Since the stitch (6) is a hydrophilic cotton thread, water mainly concentrates in the stitch (6), resulting in a knitted fabric with the functions shown in Figure 3 (O).

In the case of this knitted fabric, since it does not have a wet appearance, surface gloss and change in fabric color are suppressed, and it is suitable as a fabric for clothing for sports, especially indoor sports.

[Effect of the invention] The effects of the present invention can be summarized as follows.

The knitted fabric of the present invention is a fabric that does not feel wet against the wearer's skin even when sweating, and can be made of versatile synthetic fibers, natural fibers, and man-made fibers. Since conventional machines can be used as they are, it is possible to efficiently weave and knit moisture-transferring fabrics easily and inexpensively.Furthermore, by using various conventional fibers, a remarkable variety of fabrics can be produced. Moisture transfer fabric can be produced.Furthermore, by transferring moisture from the skin surface to the inside, not only does the skin not feel wet, but the appearance also does not feel wet, and changes in surface gloss and color are suppressed, making it suitable for sports clothing. The benefits are great.
