Description

TECHNICAL FIELD

[0001] The present application belongs to the technical field of textile fabric processing, and particularly relates to a waterproof and antibacterial moisture-conducting home textile fabric and a preparation method thereof. BACKGROUND

[0002] With the development of science and technology and the improvement of people's living standards, people's demand for household textiles is becoming more and more personalized and waterproof and antibacterial. Household textile fabrics are prone to contamination and wetting during use, and it is difficult to remove contaminants from household textile fabrics. In addition, household textile fabrics are prone to bacterial growth during use, causing human infection and transmission, which seriously affects people's life and health. In addition, household textile fabrics should also have a moisture-conducting function, so that the sweat on the skin can be quickly guided from the inner layer of the fabric to the outer layer of the fabric and dissipated into the air, solving the problem of stuffiness and sweat sticking to the body. Therefore, household textile fabrics with waterproof, antibacterial and moisture-conducting functions are of great significance.

[0003] Bamboo fiber has good air permeability, and also has natural antibacterial, bacteriostatic and acaricidal functions. In addition, bamboo fiber has excellent skin-friendliness, soft touch, skin comfort and winter warm and summer cool functions. Milk protein fiber has natural and persistent bacteriostatic function, and the broad-spectrum bacteriostatic rate of Staphylococcus aureus, fungi, Candida albicans and mold is more than 80%, which has the effect of moisturizing the skin.

[0004] N-halogen antibacterial agent has broad-spectrum, high-efficiency and renewable antibacterial effect, and has N-H bond (such as N-isopropyl acrylamide) in the molecular structure. The N-H bond is changed into N-Cl bond by chlorination treatment, which has strong oxidizing property, so the inactivation performance to bacteria is strong. At present, the treatment of household textile fabric is mostly carried out by coating finishing. The treated household textile fabric has problems such as poor water resistance, high-temperature baking treatment fabric strength reduction and the like. The use of adhesive makes the air permeability and moisture permeability of the fabric worse, affecting the inherent properties of the fabric. Therefore, the household textile fabric is treated to have waterproof, antibacterial and moisture-conducting functions, and the inherent properties of the fabric will not be greatly affected.
