Description

The present invention relates to the textile industry, more specifically to antibacterial polypeptide yarns and their constituents.

The textile industry has traditionally used both natural and synthetic fibers to create a variety of products. Each fiber has its strengths and weaknesses in terms of strength, comfort, softness and longevity. There is an ever-increasing demand for producing products with higher quality fibers, rather than simply enhancing traditional properties, providing users with more comfort, freshness and cleanliness. More functions are required for fibers. Attempts have been made to apply antibacterial chemicals to fabrics to meet the demand for modern hygienic lifestyles. Usually these agents are applied to the fabric at the finishing stage to have antibacterial properties.

However, these fabrics cannot maintain antibacterial properties for a long period of time and are washed away by washing or being exposed to ultraviolet rays. The main reason why antibacterial properties cannot be maintained for a long period of time is that such chemicals are applied together with various chemicals at the finishing stage of the fabric.
