Currently, in terms of clothing, people's requirements for clothing have shifted from the initial practical functions such as covering the body, keeping warm, and protecting to functionality, efficacy, and comfort. The popular theme of clothing and textiles has gradually shifted from simple styling to the direction centered on hydrothermal comfort and tactile comfort. Sports socks are products developed for sports, and they are required to have good moisture absorption, sweat discharge, deodorization, and wear resistance.

[0155]

[0156]

[0157] Combining Examples 1 - 12 and Comparative Examples 1 - 10 and referring to Table 1, it can be seen that by comparing Examples 1 - 5 with Comparative Examples 1 - 2, when the addition amount of the functional filler is controlled within 8 - 20 parts, the sports socks prepared have relatively good moisture absorption, sweat discharge, antibacterial and deodorant properties, and the production cost is also relatively low. Preferably, the addition amount of the functional filler is controlled within 12 - 16 parts.

[0158] Combining Examples 1 - 12 and Comparative Examples 1 - 10 and referring to Table 1, it can be seen that by comparing Examples 1 - 5 with Comparative Example 8, when the mass ratio of KH570 coupling agent to 3 - isocyanatopropylmethyldimethoxysilane is (3 - 4):(0.5 - 2), the functional filler can be better compatible and dispersed, ensuring that the sports socks prepared have relatively good moisture absorption, sweat discharge, antibacterial and deodorant properties, and relatively good mechanical strength.

[0159] Combining Examples 1 - 12 and Comparative Examples 1 - 10 and referring to Table 1, it can be seen that by comparing Examples 1 - 5 with Comparative Examples 9 - 10, when the mass ratio of silica - alumina molecular sieve powder, zirconium carbide powder, and titanium nitride powder is (6 - 8):(1 - 2):(0.1 - 0.5), the sports socks prepared have good moisture absorption and air permeability, deodorant properties, and at the same time have good abrasion resistance. Preferably, the mass ratio of silica - alumina molecular sieve powder, zirconium carbide powder, and titanium nitride powder is 8:1.7:0.3.

[0160] Combined with Examples 1-12 and Comparative Examples 1-10 and Table 1, it can be seen that by comparing Example 1, Examples 6-7 with Comparative Examples 3-5, it is known that 10-15 parts of the hydrolyzable polyester EHDPET chips can ensure that the prepared sports socks have good moisture absorption and air permeability and deodorant performance. Preferably, the addition amount of the hydrolyzable polyester EHDPET chips is relatively optimal at 12-13 parts, ensuring that the prepared sports socks have relatively good moisture absorption and sweat discharge and antibacterial and deodorant performance, and have relatively good mechanical strength.

[0161] Combined with Examples 1-12 and Comparative Examples 1-10 and Table 1, it can be seen that by comparing Examples 8-10 with Comparative Examples 6-7, it is known that when the addition amount of the hydrophilic modified polyacrylate powder is controlled at 4-12 parts, the prepared sports socks have good moisture absorption and air permeability and deodorant performance, but the wear resistance will decrease. Preferably, when the hydrophilic modified polyacrylate powder is controlled at 6-8 parts and the dosage of the functional filler is controlled at 12-16 parts, the prepared sports socks have good moisture absorption and air permeability and deodorant performance and at the same time have good wear resistance.

[0162] Combined with Examples 1-12 and Comparative Examples 1-10 and Table 1, it can be seen that by comparing Example 1 with Example 11, it is known that the addition of the silica-aluminum molecular sieve hybrid particles loaded with nano silver on the surface has a relatively good influence on the moisture absorption, sweat discharge and deodorant performance of the sports socks, and at the same time can endow them with good antibacterial and bacteriostatic performance. Therefore, the silica-aluminum molecular sieve powder is composed of the silica-aluminum molecular sieve hybrid particles loaded with nano silver on the surface and the unmodified silica-aluminum molecular sieve powder, and the mass ratio of the silica-aluminum molecular sieve hybrid particles to the unmodified silica-aluminum molecular sieve powder is (2-3):(7-8), which can endow the present application with good antibacterial and deodorant performance and good moisture absorption and sweat discharge performance.
