Abstract

The invention discloses an antibacterial non-woven fabric for a mask and a preparation method of the antibacterial non-woven fabric, and belongs to the technical field of non-woven fabric preparation. The antibacterial non-woven fabric comprises the following raw materials by weight of 80-100 parts of PET polyester chips, 5-10 parts of an antibacterial agent, 1-3 parts of a lubricant, 3-5 parts of a flexibilizer, and 5-8 parts of a plasticizer; the antibacterial agent is prepared in the process of preparing the non-woven fabric, the antibacterial agent belongs to a polymer, and the antibacterial effect cannot be reduced after the mask is used for a period of time; and meanwhile, the molecular structure of the antibacterial agent contains a large number of quaternary ammonium salt structures, the activity of metabolic enzymes in microbial cells can be reduced so as to hinder the respiratory action of the microbial cells, the production of substances required by bacteria production is interfered, the synthesis of cell walls is destroyed, then cells are killed, and therefore the antibacterial effect of the mask is ensured.

Description

technical field

[0001] The invention relates to the technical field of nonwoven fabric preparation, in particular to an antibacterial nonwoven fabric for masks and a preparation method thereof. Background technique

[0002] Most of the large-scale outbreaks in recent years are respiratory infectious diseases, such as SARS, highly pathogenic avian influenza, and H1N1 influenza. Respiratory infectious diseases are transmitted through droplets and air, and have the characteristics of rapid transmission, wide susceptible population, and high incidence, posing a great threat to public health. Wearing a protective mask can block the invasion of pathogenic microorganisms into the human body, and is an effective means to prevent the prevalence of respiratory infectious diseases and protect the health of personnel. Insisting on wearing masks can reduce the infection of influenza, and many countries stockpile protective masks as a means of non-pharmaceutical intervention to control t...

Examples

Embodiment 1

[0032] An antibacterial nonwoven fabric for a mask, comprising the following raw materials in parts by weight: 80 parts of PET polyester chips, 5 parts of antibacterial agent, 1 part of lubricant, and 5 parts of plasticizer;

[0033] Step S1: adding PET polyester chips, antibacterial agent, lubricant, and plasticizer into the extruder, and melt extruding to obtain polyester fiber;

[0034] Step S2: Weaving the polyester fiber into a cloth to prepare an antibacterial non-woven fabric for a mask.
