[0036] The preparation method of medical sanitary non-woven fabric includes the following steps:
[0037] S1: First, mix the polyester and viscose fibers in the above raw materials. After the raw materials are mixed, the raw materials are extruded and hot melted. After the extruded hot melt is completed, the raw materials are injected into the spinning equipment for spinning processing to make the raw materials Fabric blanks of different sizes are ready to be used; by using the fabric blanks made of the above-mentioned raw materials, the fabric blanks can be made to have a skin-friendly effect, which can prevent the fabrics from polluting the skin wounds, and the fabrics are relatively soft and not Will cause scratches on the skin;
[0038] S2: Put the pure water in the raw material into the reactor and heat it to 25-30℃. After the pure water is heated, put the plant essence extract, chitosan, nano silver, hyaluronic acid and calcium alginate in the raw material in sequence. Put t...
Example Embodiment
[0041] As an embodiment of the present invention, the raw materials also include polyvinylpyrrolidone and amino-terminated polyethylene glycol;
[0042] The polyvinylpyrrolidone used in the raw material is a kind of medicinal material, and has a strong bonding ability. It can exist in the form of a bonding agent in the present invention, and it also has strong stability and lubricity, thereby preventing The prepared dressing is easy to react with other substances to reduce the medical effect. At the same time, polyvinylpyrrolidone can also be combined with the dopamine mixture in the raw material to form a strong hydrogen bond, which can improve the firmness of the non-woven coating And adhesion. At the same time, polyvinylpyrrolidone can also complex with the iodine element in the raw material, thereby introducing the bactericidal group of the iodine element, and constructing a non-woven fabric surface with anti-fouling and sterilization synergistic effects. The amino-terminated...
