Abstract

The invention discloses a composite antibiotic finishing agent which comprises an organic antibacterial active component, an inorganic antibacterial active component, a penetrating agent, an adhesive, a softening agent, a suspending agent and the balance of water, wherein a non-dissolution type polymer antibacterial agent is selected as the organic antibacterial active component, and silver-loaded nanometer titanium dioxide is selected as the inorganic antibacterial active component. The invention also discloses a method for preparing the composite antibiotic finishing agent and a process used for finishing a mucilage glue and cotton fiber interweaved jacquard fabric. The main material of the composite antibiotic finishing agent for textiles is formed by the organic antibacterial active component and the inorganic antibacterial active component, thus the composite antibiotic finishing agent has a high-efficiency inhibiting capacity of more than 20 kinds of harmful bacteria such as escherichia coli, staphylococcus aureus, gonococcus and the like; the bacteria inhibiting rate is higher than 99 percent; the repelling and preventing rate of dust mites, gamasid mites and chigger is higher than 99 percent; the repelling and preventing rate of dust mites, gamasid mites and chigger is higher than 95 percent, and the killing rate is higher than 90 percent after the mucilage glue and cotton fiber interweaved jacquard fabric is washed for 50 times; and the gonococcus, escherichia coli, staphylococcus aureus and the like do not grow on the fabric which is not washed for 30 times, 50 times or 100 times, and the bacteria inhibiting rate is higher than 99 percent.

Description

technical field [0001] The invention relates to the technical field of antibacterial finishing of textile fabrics, in particular to a composite antibacterial finishing agent applied to jacquard fabrics interwoven with viscose and cotton fibers, a preparation method and a finishing process thereof. Background technique [0002] With the continuous improvement of people's living standards and the continuous updating of consumption concepts, people's requirements for decorative fabrics are also constantly increasing. Cellulose fiber-based high-count, high-density and complex decorative fabrics are more and more popular, and have become a new generation of fabrics. High-grade decorative fabric. Cotton and viscose jacquard fabrics have great market prospects due to their excellent wearing comfort, hygroscopicity, air permeability and antistatic properties. [0003] But they have some disadvantages, such as cotton fabrics are much more sensitive than synthetic fibers to the attac...
