Description

Double layer fabric

The novel provides a double-layer fabric having a higher water absorption rate and a faster moisture wicking speed.

The latest technology is the result of the application of No. 095135032 "Clothing and wicking fabrics and garments made of the fabric", which is interwoven with the first layer and the second layer. The first layer is woven from a hydrophobic fiber, and the second layer is woven from a material in which a hydrophilic fiber and a hydrophobic fiber are mixed, wherein the first and second layers are knitted, plain woven, or needled. The thorn bonding method is combined so that the requirement of moisture wicking can be achieved without chemical treatment (adding a moisture absorbent or a water repellent agent), and the problem of attenuation of the conventional moisture wicking function can be improved.

However, the patent premature has at least the following disadvantages:

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

2. The hydrophilic fiber of the second layer cannot be disposed at a high density on one side of the first layer. Therefore, the hydrophilic fiber has insufficient siphon effect on the other layer, so that the cloth is sucked. There is still room for improvement in wet wicking speed.

3. The polyester mixture of the second layer is made of Lyocell from 10% to 50% by weight. The preparation is quite complicated and has high technical requirements, so it has the disadvantage of high cost.

In view of this, the creator has carefully researched and improved, and finally developed the novel that can improve the above shortcomings.

The present invention provides a double-layer fabric interwoven with an inner layer and an outer layer, the inner layer of which is woven with polypropylene fibers having water-repellent properties, and the outer layer is woven by all-shaped cross-section yarns having hydrophilic properties, so that Greatly enhance the overall water absorption rate and moisture wicking speed. More importantly, the novel profiled yarn system is further defined as a non-circular section, thereby increasing the total surface area of the outer layer covering the inner layer and contacting the air on the other side, in addition to further adding the siphon to the inner layer of sweat. The effect is that the outer layer can absorb the sweat and can be quickly volatilized into the air due to the action of temperature or air flow. Therefore, even if the new type is used for a period of time, it will not be said to be very wet, heavy and sticky ice-ice concerns.

The third figure is a schematic diagram of the present embodiment of the perspiration.

The fourth figure is a schematic diagram of the present invention.

The fifth figure is a schematic view of another embodiment of the novel profiled cross-section yarn.

Referring to Figures 1 to 4, the present invention is formed by interweaving the inner layer 10 and the outer layer 20 by knitting, plain weaving or needle bonding; wherein the inner layer 10 is woven with polypropylene fibers 11 having water-repellent properties. The polypropylene fibers 11 are formed with a plurality of gas permeable gaps 12, and the cross-section is made by the most common circular drawing, so that the inner layer 10 has a small friction when it contacts the skin; The hydrolyzed profiled cross-section yarn 21 is woven, and the profiled cross-section yarn 21 may be selected from Polyester (PET) polyester fiber or other cellulose-like fibers (for example, cotton fiber, acrylic fiber or mucus fiber), such as As shown in the three figures, the present invention can make the sweat produced by the skin without the addition of any hygroscopic agent or water-repellent agent, and can be sufficiently siphoned by the hydrophilic outer layer 20 to the inner layer 10 (capillary action), forcing The sweat passes through the gap 12 of the inner polypropylene fiber 11 and is then fully adsorbed by the hydrophilic physical outer layer 20 to simultaneously increase the water absorption rate and the moisture wicking speed. More importantly, the novel profiled yarn 21 is further defined as a non-circular section, It is preferred to form a section of the channel 22 along the axial direction of the profiled cross-section yarn 21, as shown in the second figure, or to adopt a three-pronged section as shown in the fifth figure, which is mainly used as an increase. The outer layer 20 covers the inner layer 10 on one side and contacts the outer surface of the outer air. In addition to further adding the siphon effect on the inner layer 10, the outer layer 20 can be quickly volatilized into the air after adsorbing the sweat, so The new type can achieve moisture wicking in the shortest time, so that it can be worn with better dry comfort. The same reason, when the external water stains are like the fourth When splashed to the outer layer 20, the outer layer 20 is capable of adsorbing the water stain and does not penetrate into the inner layer 10.

It is known from the above description that the present invention has at least the following advantages:

1. The outer layer 20 of the novel is all woven by the hydrophilic profiled cross-section yarn 21, so the water absorption rate is relatively increased. In addition, the profiled cross-section yarn 21 can increase the total surface area of the contact air, so that the outer layer 20 can be heated by the sweat. Or the airflow acts quickly to volatilize into the air, so the present invention does not have the wet, heavy and sticky ice-ice concerns mentioned in the previous patent.

2. The novel profiled cross-section yarn 21 can relatively increase the total surface area of the inner layer 10 by the outer layer 20, so that the siphon effect of the sweat of the inner layer 10 can be further increased to make the moisture absorption and perspiration speed faster.

3. The outer layer 20 of the present invention is woven by using a hydrophilic profiled cross-section yarn 21, which is relatively simple and easy, so that the cost of the preparation can be effectively reduced.

In summary, the overall structural features of this creation can be said to be unprecedented in the existing structure, and it is a rather outstanding and excellent design, and no similar creation or disclosure is found in similar products. Published, it is in line with the application requirements of the new patent, and is submitted in accordance with the law. However, the above description is only a preferred embodiment of the present invention, and the scope of the present invention is not limited by the scope of the present invention, that is, the equal variation and modification of the patent application scope of the present invention is within the scope of the present creation. .
