However, this prior patent has at least the following disadvantages:

1. The hydrophilic fiber component only accounts for about a quarter, so after absorbing a certain amount of sweat, there will still be a sticky and uncomfortable feeling when wearing, so its water absorption rate is not high.

2. The hydrophilic fibers of the second material layer cannot be arranged in high density on one side of the first material layer, so the siphon effect of the hydrophilic fibers on the other side of the first material layer is not enough, so the fabric There is still room for improvement in moisture wicking speed.

Three, the polyester mixture of its second material layer is to adopt from the cloth that the Lyocell of 10% to 50% by weight is made, and this material preparation is quite complicated, and very high to technical requirement, so the shortcoming that cost remains high is arranged.

In view of this, the designer carefully researches and improves, and finally develops the utility model that can improve the above-mentioned shortcomings.

Utility model content

The purpose of the utility model is to provide a double-layer fabric with higher water absorption rate and faster moisture absorption and perspiration speed than the prior art.

In order to achieve the above object, the solution of the present utility model is:

A double-layer fabric, the fabric is interwoven with an inner layer and an outer layer; the inner layer is woven with hydrophobic polypropylene fibers; the outer layer is woven with special-shaped cross-section yarns with hydrophilic properties. The section veil is a non-circular section.

The profiled yarn is formed with grooves arranged along the axial direction.

The profiled veil adopts an X-shaped cross-section.

The special-shaped cross-section yarn adopts a trifurcated cross-section.

Detailed ways

In order to further explain the technical solution of the utility model, the utility model is described in detail through specific examples below.

Please refer to Fig. 1 to Fig. 4, the double-layer fabric of the present invention is formed by interweaving the inner layer 10 and the outer layer 20 by knitting, flat weaving or needle-punching; wherein;

The inner layer 10 is woven with water-repellent polypropylene fibers 11, and the polypropylene fibers 11 will form a plurality of air-permeable gaps 12 with each other, and its cross-section adopts the most common circular drawing, so that the inner layer 10 touches the skin It has a less frictional touch;

Outer layer 20 is all woven with special-shaped cross-section yarn 21 with hydrophilic physical properties, and this special-shaped cross-section yarn 21 can be selected Polyester (PET) polyester fiber or other class cellulose fibers (for example, cotton fiber, acrylic fiber or mucus fiber) rayon fiber), as shown in Figure 3, the utility model does not need to add any hygroscopic agent or water repellent, so that the sweat produced by the skin can be enough for the inner layer 10 to be produced by the outer layer 20 due to the hydrophilic physical property. The siphon effect (capillary action) forces the sweat to pass through the gap 12 of the inner polypropylene fiber 11, and then is fully absorbed by the hydrophilic outer layer 20, so as to increase the water absorption rate and moisture absorption and perspiration speed at the same time. More importantly, The special-shaped cross-section yarn 21 of the utility model is further defined as a non-circular cross-section, and the optimization is to form a cross-section with a channel 22 along the axial direction of the special-shaped cross-section yarn 21, as shown in FIG. The trident-shaped cross-section shown can be used. This cross-sectional shape can be achieved only by changing the drawn mold. It is mainly used to increase the total surface area of the outer layer 20 covering the inner layer 10 on one side and contacting the external air on the other side. In addition to further Adding to the siphon effect on the sweat of the inner layer 10, the outer layer 20 can quickly volatilize into the air after absorbing sweat, so the utility model can complete moisture absorption and perspiration in the shortest time, so that it has better dryness when wearing comfort. In the same way, when external water stains splash onto the outer layer 20 as shown in FIG. 4 , the outer layer 20 can absorb the water stains and prevent them from penetrating into the inner layer 10 .
