Chitin/Chitosan Fiber Properties

Chitin/Chitosan Fiber Properties

Chitin/chitosan fiber is the only positively charged organic polymer alkaline polysaccharide fiber in nature, which acts on the cytoplasm of the bacteria and can destroy the normal growth of the cytoplasmic membrane, causing disorder of cell metabolism, thus playing an antibacterial and antiseptic effect. The role of the harmful bacteria can not survive on the fiber, fundamentally eliminate the breeding of harmful bacteria and the odor produced by the bacteria. It is not like the chemical finishing agent antibacterial product may have certain irritation and harm to the human body while killing bacteria, reduce the pruritus caused by the stimulation of human metabolites on human Mu, and the washing does not affect the antibacterial property. Has a permanent antibacterial and deodorant effect.

Chitin/chitosan macromolecules have a structure similar to that of plant fibers and a structure similar to that of human ossein. This dual structure confers excellent biological activity or biocompatibility. Chitin and its derivatives have no toxic side effects on the human body. Its chemical properties and biological properties are similar to those of human tissues. It has antibacterial, anti-inflammatory, hemostatic, analgesic, and wound healing functions. It is an excellent biomedical material and can be used to manufacture artificial blood vessels, artificial skin, and surgical sutures. In addition, the complex spatial structure of chitin and its derivatives also exhibits a variety of biological activities. Its products have antibacterial, lower serum and cholesterol levels, inhibit tumor cells and promote epithelial cell growth, promote humoral immunity and cellular immunity.

Chitin/chitosan fibers have a large number of hydrophilic groups such as hydroxyl and amino groups on the Oita-Yakimoto chain, so the fibers have very good hydrophilicity and high hygroscopicity. The equilibrium moisture regain of chitin fiber is generally between 12% and 16%. Under different molding conditions, the water retention value is about 130%. Because of its unique fiber molecular structure, it has strong white and seven wet functions, and it has a good moisturizing and curing effect on the skin.

Chitin and its derivatives decompose into low-molecular substances under the action of enzymes. Therefore, its products used for general organic germanium can be biodegraded and completely absorbed by the organism. After being discarded, it can be decomposed by microorganisms, and the natural decomposition rate in soil is extremely high, which is 2 times higher than that of starch, and it will not cause environmental pollution.
