AI Technical Summary

Problems solved by technology

Silicone water-repellent finishing agents and conventional polymer emulsion finishing agents have many advantages, such as environmental friendliness, low cost, and good heat resistance, weather resistance and UV resistance, etc., but these finishing agents have insufficient mechanical strength , poor adhesion and other deficiencies, can not maintain good waterproof performance for a long time
In addition, most of the existing waterproof finishing agents have a single function, and mainly can only play a waterproof role.
Although there are also researches on multi-functional waterproof finishing agents, such as waterproof and antibacterial effects, etc., the durable waterproof and durable antibacterial properties of these waterproof finishing agents need to be improved
Especially because the antibacterial agent in the existing waterproof finishing agent is only simply blended in the waterproof finishing agent component, the interaction between the antibacterial agent and the waterproof finishing agent is relatively weak, causing the antibacterial agent component to be easily washed in the process of textile washing and the like. Shedding, can not play a long-term antibacterial effect

Abstract

The invention relates to the waterproof processing and finishing technology, in particular to a waterproof antibacterial fabric finishing agent and an application thereof. The waterproof antibacterialfabric finishing agent is composed of the following components by weight parts of: 30 to 45 parts of acrylate copolymer, 5 to 10 parts of silica solution, 1 to 8 parts of long-acting antibacterial agent, 1 to 5 parts of dispersant, and 40 to 60 parts of water. In the invention, through adopting the compounded antibacterial agent components, the dispersion and stability of the long-acting antibacterial agent are improved, and at the same time, the long-acting antibacterial effect of the waterproof antibacterial fabric finishing agent is significantly improved. In addition, the waterproof antibacterial fabric finishing agent disclosed by the invention does not contain PFOS(perfluorooctane sulfonate) and PFOA(perfluorooctanoic acid), which is easily biodegraded, has no bioaccumulative properties, is less harmful to the human body, and is a relatively safe and environmentally friendly product.

Description

technical field [0001] The invention relates to waterproof processing and finishing technology, in particular to a waterproof and antibacterial fabric finishing agent and its application. Background technique [0002] With the improvement of living standards, people's requirements for clothing fabrics and other products are getting higher and higher. Functional textiles such as personalization, high-grade and moisture absorption, breathability, perspiration, quick drying, deodorant and antibacterial, and anti-ultraviolet have become more and more popular. Become the development trend of textile and garment fabrics. Waterproof, oil-repellent, easy-to-decontamination multi-functional finishing can significantly improve the surface properties of the fabric, making the fabric not easily wetted and stained by water, oil, coffee and other stains. Silicone water-repellent finishing agents and conventional polymer emulsion finishing agents have many advantages, such as environmenta...
