Abstract

The invention discloses flexible antibacterial medical non-woven fabric and a preparation method thereof. The flexible antibacterial medical non-woven fabric is prepared from, by weight, 48-65 parts of polypropylene fibers, 12-25 parts of tea fibers, 28-42 parts of polyvinyl alcohol fibers, 1-2 parts of sodium pyrrolidone carboxylate, 0.5-1 part of allantoin, 2-4 parts of fibrin glue and 1.5-3 parts of genipin. According to the flexible antibacterial medical non-woven fabric and the preparation method thereof, the prepared product has excellent flexibility, antibacterial performance and good comfort and is beneficial to wound healing and skin relieving of a patient.

Description

technical field [0001] The invention relates to the technical field of nonwoven fabrics, in particular to a flexible antibacterial medical nonwoven fabric and a preparation method thereof. Background technique [0002] Non-woven fabrics, also known as non-woven fabrics, are composed of directional or random fibers, and are called cloth because of their appearance and certain properties. Due to the excellent characteristics and low processing cost of non-woven fabrics, they are widely used in the fields of medical treatment, home decoration, clothing and industrial fabrics. Among them, when medical non-woven fabrics are used for wound dressing, due to direct contact with the skin, there are certain requirements for their flexibility and antibacterial properties. At present, the flexibility and antibacterial properties of medical non-woven fabrics still need to be improved. Contents of the invention [0003] Based on the technical problems in the background technology, the...
