Abstract

The invention discloses a non-woven fabric for medical mask production and a preparation process, and belongs to the technical field of non-woven fabrics. The non-woven fabric is prepared from the following components in parts by weight: 8-12 parts of nano titanium dioxide powder, 5-9 parts of silica-alumina gel, 6-12 parts of a bactericide, 35-48 parts of polypropylene, 15-18 parts of cotton fibers, 20-25 parts of a leveling agent, 8-10 parts of maleic resin, 10-15 parts of modified polyvinyl alcohol, 4-8 parts of saturated erucamide and 5-10 parts of an antioxidant. The added nano titanium dioxide powder has anti-line, antibacterial, self-cleaning and anti-aging properties, meanwhile, the added silica-alumina gel can catalyze the reaction of the nano titanium dioxide powder and saturatederucamide to enhance the sterilization effect of the non-woven fabric, meanwhile, the non-woven fabric is soaked in the bactericide to enhance the antibacterial effect of the non-woven fabric, and the antibacterial time of a mask prepared from the non-woven fabric can be effectively prolonged.

Description

technical field [0001] The invention relates to a non-woven fabric and a preparation process, in particular to a non-woven fabric for the production of medical masks and a preparation process, belonging to the technical field of non-woven fabrics. Background technique [0002] Medical masks are mostly made of one or more layers of non-woven fabrics. The main production processes include meltblown, spunbond, hot air or acupuncture, etc. It has the effects of resisting liquids, filtering particles and bacteria, and is a medical protection. Textiles; 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. [0003] The traditional non-woven fabrics for medical masks have the following deficiencies: (1) the existing non-woven fabrics for medical masks have poor air permeability, and the bacteria-filtering performance of the masks becomes weak after wearing them for a...
