Description

technical field [0001] The invention relates to the technical field of textiles, in particular to a casein-chitosan composite fiber and a preparation method thereof, a casein-chitosan composite fabric and its preparation and application. Background technique [0002] The skin is the largest organ of the human body, composed of the epidermis, dermis and subcutaneous tissue. It is a natural barrier between the human body and the outside world. It plays the roles of protection, sensation, temperature regulation, secretion, excretion, absorption and immunity in the human body. The loss of water, electrolytes and acid-base balance will cause imbalance of water, electrolyte and acid-base balance, which will affect the normal absorption and metabolic balance of the human body. The skin is the first layer of barrier for the body to defend against external invasion, and it is also the largest tissue in the body. Foreign substances and microbial attack. There are many reasons for ski...
