Ongoing research.

The development of world textile technology has been focused on the limit of functionality, spinning speed, fiber thickness and strength, and the development of new fibers using new materials. In pursuit of functions such as keeping warm, moisturizing, antifouling, deodorant, breathable and water repellent, the company has focused on softness of fiber, dry and natural fiber of fiber.

Recently, the interest in health and leisure activities and the well-being trend of the five-day work week in Korea are demanding the development of materials with various functionalities and durability, and the role of functional processing in textiles is highlighted.

In order to improve such high-performance processing and durability, the trend of recent convergence of traditional textile technologies such as ceramics and polymers, new materials technologies such as antimicrobial, biotechnologies such as antimicrobial nozzles, micro-processing technologies such as microscopic nozzles, thermochromic and sensor technologies, and nanotechnology Is showing.

These highly functional textile materials are used not only for clothing but also for non-apparel textiles, and are used in automobiles, aviation, electronics, and medical industries. The demand for high-performance fibers continues to grow, and in advanced countries, more than 60% of fiber demand has been replaced by high-performance fiber, but Korea is still in the early stage of development, with less than 30% of fiber demand.

The development of functional materials began with efforts to give absorbent and hygroscopic properties to synthetic fibers and to bring them closer to natural fibers. At present, synthetic fibers with more absorbent and hygroscopic properties than natural fibers have emerged. Materials that give excellent functions such as oil repellent, antifouling, antibacterial and deodorant are being developed continuously. In particular, the demand for functional fibers related to life safety, functional and health is gradually increasing, and the development of new functional fibers for replacement of demand is being made continuously.

In particular, not only good human-friendly, but also widely used as a natural material, and research and development of functional processing of wool and wool blend fibers, which are high-quality materials are continuously made.

In response to this, post-processing technologies using new nano-processing agents have been researched and developed. However, especially in the processing of composite materials including wool, acetate and polytrimethylene terephthalate, multi-processing with water repellent, antifouling, oil repellent, deodorant and antibacterial functions Due to the excessive use of various functional processing agents of the silver polymer and the surfactant type, the functions are not sufficiently expressed, and it is difficult to commercialize due to the deterioration of the feel of the textile products and the decrease in tear strength. In particular, in addition to the shrinkage problem of the wool, in the case of acetate and poly ethylene terephthalate is sensitive to the heat treatment temperature, there was a problem that the unique texture of the material disappears because the curing proceeds at a processing temperature of 110 ℃ or more.

Therefore, the present invention solves the problems of the prior art, it is possible to uniformly dye and high-quality dyeing of the dyeing process while minimizing the dyeing process without lowering the texture and tear strength of the textile products and at the same time excellent water repellent, antifouling, oil repellent, deodorant It is a technical problem to provide a composite processing agent and a processing method that can express antibacterial function.
