Description

Technical Field

[0001] This invention relates to the field of fabric technology, specifically to a moisture-wicking fabric and its preparation process. Background Technology

[0002] As people become more health-conscious, consumers are demanding higher performance from clothing fabrics. Traditional clothing fabrics are mostly made of pure cotton or ordinary synthetic fibers. Although pure cotton fabrics have good moisture absorption, they are slow to wick away sweat. When exercising, sweat adheres to the fabric, making the clothes damp and heavy, and they are not easy to dry. This can easily breed bacteria, produce odors, and affect the wearing experience.

[0003] In order to optimize the moisture-wicking performance of existing fabrics, it is easy to affect the elasticity and abrasion resistance of the product. It is difficult to balance and coordinate the improvement of the product's performance, and the product's poor weather resistance stability limits the product's efficiency. Summary of the Invention

S02: The carbon nanotubes are first placed in a proton irradiation chamber and irradiated for 1 hour at an irradiation power of 350-400W. After irradiation, the irradiated carbon nanotubes are obtained. Irradiated carbon nanotubes and graphene compound solution were mixed at a weight ratio of 5:3 and ball-milled at a speed of 1500 r / min for 2 hours. After ball milling, the mixture was filtered and dried to obtain the modifier.

[0008] Preferably, the impregnation treatment is carried out by ultrasound, with an ultrasonic power of 350-400W and an impregnation time of 1 hour.

[0009] Preferably, the sodium dodecylbenzenesulfonate solution has a mass fraction of 5-8%.

[0010] Preferably, the preparation method of the functional additive is as follows: 2-3 parts by weight of titanium oxide, 3-5 parts by weight of aluminum borate whiskers and 2-3 parts by weight of boron nitride are mixed evenly and then sintered to obtain a functional sintered body. 5-8 parts by weight of functional sintered body and 6-9 parts by weight of sol solution were mixed and ball-milled at a speed of 1500 r / min for 2 hours.

The modified polyester filaments are improved and optimized using polyester resin and modifiers. The carbon nanotubes in the modifiers are activated by irradiation and then ball-milled with a graphene blending solution. The graphene in the graphene blending solution serves as the matrix and is combined with diatomaceous earth, sodium carboxymethyl cellulose, and chitosan solution. Through the synergistic effect of the raw materials, the moisture-wicking properties, elasticity, and abrasion resistance of the polyester filaments are enhanced. The functional yarn is made by processing modified spandex fibers and combed cotton on a spinning machine, combined with functional additives and acrylic fibers. The resulting functional yarn optimizes the performance coordination and stability of the system. The modified spandex fibers are improved through a modifying solution containing silane coupling agent KH550, lanthanum oxide, nano-attapulgite, and other raw materials. The layered nano-attapulgite interweaves within the system, enhancing the yarn's performance stability. The functional additives, including functional sintered bodies and sol-gel mixtures, are ball-milled. The functional sintered body is improved and optimized by sintering titanium dioxide, aluminum borate whiskers, and boron nitride. At the same time, the whisker structure of aluminum borate whiskers is harmonized with boron nitride and titanium dioxide raw materials, as well as the harmonized sol solution. The nano-silica sol, sodium silicate solution, and zinc nitrate solution in the sol solution are combined and strengthened through the composite of raw materials.

[0070] Table 1. Product performance test results of Examples 1-3 and Comparative Examples 1-13: From Examples 1-3 and Comparative Examples 1-13, it can be seen that Example 3 of the present invention has the best moisture permeability, water absorption rate, elastic recovery rate and abrasion resistance.

In the preparation of functional yarns, the modified spandex fibers were not treated with a modifying solution, lanthanum oxide and nano-attapulgite were not added to the modifying solution, and functional additives were not added in the preparation of functional yarns. The performance of the products all tended to deteriorate to varying degrees. In particular, the performance deterioration was more obvious when no functional additives were added. In the preparation of functional additives, no functional sintered body is added; in the preparation of functional sintered body, no boron nitride and titanium oxide are added; in the preparation of functional sintered body, no aluminum borate whiskers are added; in the preparation of functional additives, no sol solution is added; and in the sol solution, no nano-silica sol or sodium silicate solution is added. The performance of the products in these cases tends to deteriorate to varying degrees. The functional additives prepared using the specific method of this invention, combined with the sol solution, exhibit the most significant performance improvement. Other methods used to replace them are not as effective as those of this invention. Furthermore, the preparation method of the functional additives is unique, and other methods used to replace them are not as effective as those of this invention.
