Abstract

The invention relates to the field of non-woven fabric, and particularly discloses antibacterial non-woven fabric and a preparation process thereof. The antibacterial non-woven fabric comprises the following raw materials in parts by weight: 50-60 parts of polypropylene resin; 10-12 parts of 3,4-dihydroxy-5-nitro-benzaldehyde; and 8-10 parts of nano TiO2. The preparation process comprises the following steps: S1, preparing cellosilk; S2, preparing a fiber net; and S3, preparing the non-woven fabric. According to the antibacterial non-woven fabric, 3,4-dihydroxy-5-nitro-benzaldehyde is adopted, aldehyde groups in molecular structure of the 3,4-dihydroxy-5-nitro-benzaldehyde can be combined with amino groups on enzyme molecular structures in microbial cells, so that the enzyme activity is inhibited, then cell growth and proliferation of microorganisms are inhibited, breeding of the microorganisms on the surface of the non-woven fabric is reduced, thus mildewing of the surface of the non-woven fabric is reduced, and the antibacterial effect of the non-woven fabric is improved; in addition, according to the preparation process, needling is conducted on the fiber layer through the component density, the compactness of connection between the cellosilk is improved, and thus the prepared non-woven fabric is better in toughness.

Description

technical field [0001] The application relates to the field of non-woven fabrics, more specifically, it relates to an antibacterial non-woven fabric and its preparation process. Background technique [0002] Non-woven fabrics, also known as non-woven fabrics, are composed of oriented or random fibers. It is called cloth because of its appearance and certain properties. [0003] The non-woven fabrics in the prior art are widely used in the medical and health industry, and are widely used in production and life. For example, it is widely used in paper diapers, sanitary napkins, panty liners, wet wipes, Band-Aids, masks, food packaging bags and other products. [0004] The inventor found that after the non-woven fabric is placed for a long time, mildew will appear on the surface, which affects the processing and use of the non-woven fabric, and needs to be improved. Contents of the invention [0005] In order to improve the problem that mildew will appear on the surface of...
