Abstract

The invention discloses a preparation process of non-soaking antibacterial and deodorant cotton. The preparation process of the non-soaking antibacterial and deodorant cotton comprises the following steps of pretreating dry cotton fibers; performing antibacterial treatment on the pretreated cotton fibers to obtain antibacterial cotton fibers; carrying out antibacterial treatment on polyurethane fibers to prepare antibacterial polyurethane fibers; and blending and rolling the prepared antibacterial cotton fibers, antibacterial polyamide fibers, linen fibers and polylactic acid fibers to preparethe antibacterial and deodorant cotton. According to the preparation process of the antibacterial and deodorant cotton, common cotton fibers are subjected to antibacterial treatment and blended withthe antibacterial polyamide fibers to achieve antibacterial and bactericidal effects, and odor is avoided. The prepared antibacterial and deodorant cotton is excellent in antibacterial performance andwashing resistance, and natural balance of skin cannot be damaged.

Description

technical field [0001] The invention relates to the technical field of fabric treatment, in particular to a preparation process of non-soaked antibacterial and deodorant cotton. Background technique [0002] People will inevitably come into contact with various bacteria, molds, viruses and other microorganisms in daily life. Since ordinary cotton textiles do not have antibacterial properties, the residual human body secretions provide protection for microorganisms during people's daily wear. A good living environment, especially in a high temperature, humid, poorly ventilated environment, will breed and reproduce a large number of bacteria and molds, making cotton fabrics smelly, moldy and discolored, and even seriously affect human life and health. Therefore, people modify cotton fabrics And the demand for antibacterial functionalization is getting stronger and stronger, and the requirements are getting higher and higher. [0003] The principles and methods of preparing an...
