Abstract

The invention discloses a preparation method of a high-performance medical textile material and relates to the field of medical materials. The preparation method comprises treating a polypropylene non-woven fabric through plasma, preparing a sodium alginate solution, dissolving DCC and N, N-hydroxysuccinimide in water to obtain a solution, treating the polypropylene non-woven fabric treated by plasma through the solution, adding the sodium alginate solution into the polypropylene non-woven fabric for a reaction so that sodium alginate is effectively cross-linked and grafted to the surface of the polypropylene non-woven fabric, and bonding the polypropylene non-woven fabrics as upper and lower surfaces of the fabric material and a polyester fabric as a middle layer through a polyurethane hot melt adhesive to obtain the medical textile material. The medical textile material has good moisture and air permeability, a certain antibacterial property and large elasticity, is prepared throughsimple processes, realizes a low cost and can be used in field of medical protective clothing and medical surgical caps.

Description

Technical field: [0001] The invention relates to the field of medical materials, in particular to a method for preparing high-performance medical textile materials. Background technique: [0002] Since entering the 21st century, my country's non-woven fabric technology has made great progress, and the development of the production and application of medical non-woven fabrics is particularly prominent. However, my country's medical textiles still have problems such as poor quality and blank qualification certification. In order to re-grasp the frequency of the development of medical textiles in our country, and to study its development direction, I have made research on this. The application of textile materials in the medical field started very early. As early as 4000 years ago, the ancient Egyptians knew how to use linen yarn bonded with natural glue to suture wounds so that the wounds could heal in time, and the mummy was wrapped with fabric treated with medicinal plants to pr...
