Abstract

The invention belongs to the field of manufacturing of articles for daily use, and discloses a degradable spinning raw material, a degradable fiber membrane and a degradable protective cover. The degradable spinning raw material comprises the components in parts by weight: 55-85 parts of a medical-grade or food-grade polymer base material, 0.5-8 parts by weight of a nano non-metal photocatalytic material, 0.5-5 parts by weight of an auxiliary agent, and 2-44 parts by weight of a solvent, wherein the auxiliary agent comprises an antioxidant and a lubricant. The degradable spinning raw materialis environmentally friendly, has the performance of killing viruses and bacteria, and is suitable for being used as an antibacterial filtering material of protective covers such as masks and facial masks.

Description

technical field [0001] The invention relates to the field of daily necessities manufacturing, in particular to a degradable spinning raw material, a degradable fiber film and a degradable protective cover. Background technique [0002] In public health safety incidents, the use of protective shields or protective clothing plays a vital role in reducing the impact and scope of infectious incidents and enhancing personal protection. At the same time, in the season when influenza and viruses are active, using protective covers, such as masks, can also effectively prevent and reduce the incidence of respiratory diseases. [0003] With the increase in the use of protective covers or protective clothing, the number of discarded protective covers or protective clothing has increased rapidly, making the problems of recycling and secondary pollution of discarded protective covers or protective clothing increasingly prominent. [0004] The use and disposal of protective covers or pro...
