Study on the long-term modification of fabric surface by novel glycosylamide organosilicones quaternary ammonium salts

As a widely used fabric, polyester cloth can be modified by finishing to have more excellent properties. Quaternary ammonium surfactants are widely used in textiles as antibacterial finishing agents, but their long-term bacteriostatic properties and multi-functionality are insufficient. This paper studies the application properties of two novel glycosylamide organosilicon quaternary ammonium salts on fabrics, including long-lasting antibacterial effects, softness, foaming, antistatic properties, and self-cleaning. The results showed that the softness of the cloth after cleaning of the two samples was better than that of standard detergents, and the rewettability was better than that of traditional silicone quaternary ammonium salts, and it had certain antistatic and self-cleaning capabilities. And the sample has good foaming and foam stabilization at low flow rates. Through thermogravimetric, skin irritation, and acute oral toxicity tests, it was proved that the samples were not easy to degrade at high temperatures, and were non-irritating and non-toxic to the skin. After 15 times of soaking and washing, the inhibition effect of both samples against Staphylococcus aureus reached 99 %. The results show that the sample application has excellent properties on fabrics and can survive continuously, which provides a new idea for fabric surface modification and broadens the application field of fabrics.
