[0002] Fabrics play an extremely important role in the field of clothing. They directly affect the appearance, comfort, functionality and durability of clothing. Using fabrics made of different materials to sew clothing can provide users with different wearing experiences. It not only affects the appearance and comfort of clothing, but also determines the functionality and durability of clothing. The existing summer uniform fabrics are limited by the materials themselves. The clothes prepared are prone to static electricity and do not have UV protection function, which affects the comfort of users wearing. At the same time, the auxiliary preparations added in the fabric preparation process are mostly filled in the surface of the fabric by impregnation. The limited binding strength makes it easy to fall off during repeated use, affecting the timeliness of the auxiliary agent function. In addition, water is required as a medium for dyeing during the fabric processing process, which increases the consumption of water resources and the discharge of wastewater. At the same time, the chemical auxiliaries used for dyeing will increase the pollution to the environment. Therefore, it is very necessary to design a highly comfortable, UV-proof and anti-static summer uniform fabric and its preparation process. Summary of the Invention

[0073] In the above step 6, the antistatic agent is applied to the UV-resistant fabric prepared in the above step 5 by a padding method to obtain an integrated fabric, which is then set aside. The process of applying the antistatic agent by the padding method is as follows: first, the UV-resistant fabric is fully soaked in the finishing liquid through a padding device, while controlling the liquid content to be between 70%, and then padding the fabric in the padding liquid for 50 minutes; after the padding treatment, the fabric needs to be removed from the padding liquid and continuously dried at a temperature of 118° C. for 17 minutes;

[0074] In the above step seven, the integrated fabric prepared in the above step six is ​​subjected to a post-finishing process, and after the post-finishing process, a highly comfortable anti-UV and anti-static summer uniform fabric is obtained, and performance testing is performed; the post-finishing process includes softening finishing, anti-wrinkle finishing and setting treatment, wherein the softening finishing uses a silicone oil softener to soften the fabric; the anti-wrinkle finishing applies a resin finishing agent to improve the wrinkle resistance of the fabric; the setting treatment is to stand at 180°C to set the fabric to ensure the stability of the fabric size.

[0075] The high-comfort anti-ultraviolet and anti-static summer uniform fabrics obtained in the above examples were subjected to performance tests and compared with ordinary summer uniform fabrics on the market. The results are shown in the following table:

[0076] UPF value Surface resistance test Air permeability test Example 1 64.5 1.05*10^9Ω / sq 287mm / s Example 2 63.4 1.01*10^9Ω / sq 274mm / s Example 3 65.2 1.10*10^9Ω / sq 281mm / s Example 4 62.9 1.05*10^9Ω / sq 285mm / s Example 5 63.4 1.07*10^9Ω / sq 277mm / s Comparative Example 51.2 1.53*10^10Ω / sq 214mm / s

[0077] Based on the above, the advantages of the present invention are that, when used, the UPF value of the fabric is improved by adding an anti-ultraviolet agent, and ultraviolet damage is reduced. At the same time, PLA fiber is used to replace part of the polyester fiber material to improve the environmental protection and biodegradability of the fabric. The added cotton fiber can improve the hygroscopicity and comfort, and increase the skin-friendliness of the fabric. The added antistatic agent can prevent static electricity on the fabric, making the wearer more comfortable. The yarn is surface-treated before dyeing, and plasma is used to treat the surface of the fabric during the process to enhance the binding force between the fiber and the functional additive, and prevent the functional additive from falling off during use, thereby ensuring the service life of the fabric; during the dyeing process, supercritical CO2 is used instead of water as the dyeing medium for treatment, and dyeing additives composed of pectinase and cellulase are added to the medium to replace chemical additives, thereby reducing water resource consumption and wastewater discharge, and reducing the pollution of fabric production to the environment.
