The designations in the figures illustrate the following: 1-an inner layer; 2-an intermediate layer; 3-an outer layer; 4-microporous membrane.
Detailed Description
The utility model is further described with reference to the following figures and specific examples.
Example one
This embodiment will be described in detail with reference to fig. 1. The moisture absorption and ventilation spunlace nonwoven fabric for medical and health comprises an inner layer 1, a middle layer 2 and an outer layer 3 which are compounded; the inner layer 1 is carboxymethyl chitosan/ES fiber spunlace nonwoven fabric, the middle layer 2 is wood pulp spunlace nonwoven fabric, and the outer layer 3 is soybean protein fiber spunlace nonwoven fabric; and an amino-terminated hyperbranched polymer is attached to the fiber surface of the wood pulp spunlace non-woven fabric.
Chitosan is a deacetylated product of chitin, is the only natural basic polysaccharide discovered up to now, has biocompatibility and biodegradability, and can be used for stopping bleeding, preventing corrosion and promoting wound healing. Chitosan can activate a series of biological effects of an organism system and a mediation organism system, improves the system function of phagocytes, has bacteriostasis, and is widely applied to biomedical dressings. The carboxymethyl chitosan product, namely carboxymethyl chitosan, not only retains the excellent performance of chitosan, but also greatly improves the water solubility, antibacterial property and degradability of the chitosan. The carboxymethyl chitosan fiber can rapidly form hydrogel with a three-dimensional network structure after contacting deionized water, has good moisturizing performance, accords with the moist environment healing theory, can provide more effective and faster treatment for chronic wounds with longer healing time, and is applied to novel medical dressings and is greatly approved in the medical field.
