Background
In recent years, with the improvement of people on healthy life and green environmental protection concepts, the proportion of functional and environmental protection fabrics in the garment fabric market is continuously increased. The functional textile has one or more of the effects of resisting bacteria, retarding flame, repelling water and oil, preventing ultraviolet rays, resisting fragrance and the like besides the basic use value of the textile, and is mainly woven by adopting novel functional yarns developed through physical or chemical modification as raw materials, or the functional auxiliary agent is added in the production process of the fabric to finish the fabric, so that the fabric has specific functions and super-strong performance.
Chinese published patent document (CN112252037A) discloses an antibacterial finishing process of cotton fabric. The finishing process comprises the following steps: s1, pretreatment: pretreating pure cotton gray cloth to obtain pretreated gray cloth; s2, dyeing: dyeing the pretreated gray cloth obtained in the step S1 to obtain dyed gray cloth; s3, antibacterial finishing: performing antibacterial finishing on the dyed gray cloth obtained in the step S2 by using an antibacterial finishing agent to obtain antibacterial gray cloth; in step S3, the antibacterial finishing agent includes the following components in parts by weight: 55-65 parts of an antibacterial agent; 10-20 parts of dopamine. The application has the advantage that the antibacterial effect of the cotton fabric can be improved. However, this antimicrobial effect is not durable, and the antimicrobial agent is easily lost after many washes to weaken or even lose the antimicrobial effect.
