Problems solved by technology

In particular, chitosan and polyethylene oxide have a certain degree of water solubility, which will swell and disintegrate after forming the material, which will also cause a burst release effect in the later stage of release.

Abstract

The invention discloses a preparation method of an aromatic, antibacterial and waterproof non-woven fabric and belongs to the field of textile engineering. The provided preparation method comprises the steps of (1) wrapping an antibacterial agent in a stable siliceous body formed by organic and inorganic composite lipid; (2) completely dissolving a certain amount of chitosan and polyethylene oxidein a 90% acetic acid solution, and uniformly stirring the mixture to obtain a spinning solution; (3) adopting the spinning solution for carrying out electrostatic spinning to obtain a chitosan/polyethylene oxide nanofiber; (4) soaking the nanofiber in an antibacterial siliceous body solution for a grafting reaction, treating the nanofiber by a plasma processor, and then air-drying the nanofiber;(5) soaking the air-dried nanofiber in an ethanol solution containing organic and inorganic composite lipid, carrying out negative-pressure flash explosion, washing the nanofiber with water, and performing drying at the high temperature to obtain the aromatic, antibacterial and waterproof non-woven fabric. The non-woven fabric has the advantages of lasting antibacterial effect, good waterproof performance and certain plant fragrance.

Description

technical field [0001] The invention relates to the field of textile engineering, in particular to a method for preparing an aromatic antibacterial and waterproof nonwoven fabric. Background technique [0002] When traditional non-woven fabrics, cotton yarns and other materials are used as medical fabrics, due to the thicker fabric fiber diameter and larger fiber pore size, the filtering effect on particles carrying pathogenic bacteria is not ideal. However, nanofibers are used as medical fabrics, and their ultra-fine diameter and extremely small porosity can effectively filter substances such as disease-bearing particles. However, as antibacterial nanofibers, if the antibacterial agent and high polymer are simply electrostatically blended, the phenomenon of burst release of antibacterial drugs will inevitably occur. [0003] In addition, due to the loose surface of the non-woven fabric, its water-permeable and water-conducting properties are better, and vice versa, its wat...
