Problems solved by technology

[0011] At present, hydrophilic and water-absorbing natural fibers are mostly used as the fiber raw materials for moisture-absorbing and sweat-wicking fabrics, and natural fibers can absorb sweat in the fibers, which not only absorbs sweat but also retains weight, and cannot wick and guide sweat.
Knitted fabrics with a uniform and loose structure are mostly used, which have no water-conducting differential power, and can only be absorbed and stored in the fibers, and cannot wick away sweat.

Embodiment 1

[0046] Polyester fabric: The contact angle of the polyester fiber after plasma treatment is 60°. After the front surface of the fabric is pressed, the contact angle of the surface layer is 90°. Under normal conditions, the moisture regain of polyester fiber is 0.4%, and after plasma treatment, it can reach 1.6-1.8%. Therefore, the moisture regain of the polyester fabric with double-sided water-repellent and sweat-wicking functions made of this fiber is 2.0- 2.1%. When the water absorption of the polyester fabric reaches 25% of its own weight, which is equivalent to the moisture regain of the fabric is 27.1%, after placing it for 30 minutes, the moisture regain of the polyester fabric returns to 2.3%; when the water absorption reaches 50% of the polyester fabric itself, place it for 45 minutes, the fabric The moisture regain dropped from 52.0% to 2.8%, all in a dry state. On the other side, after 1 minute of water supply, there is no water trace and normal contact pressure (3g...

[0048] Polypropylene fabric: The contact angle of the polyester fiber after plasma treatment is 73°. After the front surface of the fabric is pressed, the contact angle of the surface layer is 161°. Under normal conditions, the moisture regain of polypropylene fiber is 1.0%, and it can reach 1.7-1.8% after plasma treatment. Therefore, the moisture regain of the polypropylene fabric with double-sided water-repellent and sweat-wicking functions made of this fiber is 2.5-1.5%. 2.6%. When the water absorption of the polyester fabric reaches 25% of its own weight, which is equivalent to the moisture regain of the fabric is 27.6%. After placing it for 30 minutes, the moisture regain of the polyester fabric returns to 2.3%. When the water absorption reaches 50% of the polyester fabric itself, place it for 45 minutes. The moisture regain dropped from 50% to 2.8%, all in a dry state. On the other side, after 1 minute of water supply, there is no water trace and normal contact pressure...

[0050] Polylactic acid fiber fabric: The contact angle of the polylactic acid fiber after plasma treatment is 55°. After the front surface of the fabric is pressed, the contact angle of the surface layer is 158°. 32°. Under normal conditions, the moisture regain of polylactic acid fiber is 0.5%, and it can reach 2.8-2.9% after plasma treatment. 3.0 to 3.1%. When the water absorption of the polylactic acid fiber fabric reaches 25% of its own weight, it is equivalent to a moisture regain of the fabric of 28.1%. After placing it for 30 minutes, the moisture regain of the polylactic acid fiber fabric returns to 2.3%; when the water absorption reaches 50% of the polylactic acid fiber fabric itself , placed for 45min, the moisture regain of the fabric decreased from 50% to 3.0%, all in a dry state. On the other side, after the water supply is completed for 1 minute, there is no water trace and normal contact pressure (3g / cm2) 2 ) was measured to be 1.4% wet. In the measurement o...

Abstract

The invention relates to a double-sided functional fabric with a gradient structure for water-repellent and sweat-wicking and its preparation. The fabric is wettable, that is, the surface contact angle is less than 90°, but does not absorb moisture itself, that is, the moisture regain of the fiber is lower than 2%. Fabrics made from purely spun yarns. And the front of the fabric is compacted and ultra-thin surface water-repellent finishing, and the reverse is loosened and hydrophilic, so that the surface layer of the fabric front forms a water-repellent functional layer; the reverse surface layer forms a fast water-absorbing functional layer; and In the middle main layer of the fabric, holes are formed from large to small water-conducting functional layers. In this way, the surface of the fabric is water-repellent outward, and there is space and surface area for moisture to escape; the reverse side of the fabric quickly absorbs water into the fabric and conducts water outward in the fabric as a whole. Such fabrics can be used in clothing and home textiles.

Description

technical field [0001] The invention relates to a double-sided functional fabric with a gradient structure for water repellency and perspiration and its application. Background technique [0002] The water-repellent and sweat-wicking double-sided functional fabric is developed on the basis of improving the fabric's thermal and humid comfort. It solves the realization of the waterproof and water-conducting functions of the front and back (contacting the human body surface) of the fabric, that is, the inner and back of the fabric have a certain moisture-wicking and sweat-wicking function, and the outer front of the fabric has good water repellency. It is a typical functional fabric with double-layer structure, but it does not solve the problem of the connection between layers and the transition conduction in layers. For example, the isolation effect of the water-repellent front prevents external water from entering the fabric to achieve the purpose of water repellency, but at...
