Problems solved by technology

[0004] Chinese patent 201110362190.8 discloses an antistatic non-woven fabric and its preparation method. This is a composite fiber with a skin-core structure. The core layer is polypropylene, and the skin layer is a blend of polypropylene and conductive fillers. The flexibility of the textile needs to be further improved
[0005] Due to the strong polarity of the antistatic agent, the compatibility with polyester is poor, especially at high temperature, it is easy to precipitate, which leads to the reduction of antistatic performance of polyester materials, which greatly limits the application of polyester materials.

Abstract

The invention relates to an anti-static non-woven fabric and a preparation method thereof. The anti-static non-woven fabric is prepared from the following components in parts by weight: 85-98 parts of polyester, 2-10 parts of a polyamide polymer, and 0.5-5 parts of an antistatic agent. The non-woven fabric prepared by adopting the preparation method is smaller in diameter of fibers; the obtained non-woven fabric has the advantages of large specific surface area, high porosity, excellent filtering efficiency, good softness, strong comfortable feeling and the like. The non-woven fabric can be widely applied to fields such as medical and industrial masks, thermal insulation materials, filtering materials, medical and health materials, oil absorption materials, wiping cloth, battery separators and sound insulation materials.

Description

technical field [0001] The invention belongs to the application field of polymer materials and the technical field of non-woven fabric manufacturing, and relates to an antistatic non-woven fabric and a preparation method thereof. Background technique [0002] The conductivity and dielectric constant of conventional polymer materials are low, and fabrics made of polymer materials are prone to static electricity during use, causing problems such as staining and sticking dust. Therefore, it is more and more important to improve the antistatic properties of materials. [0003] Non-woven fabric, also known as non-woven fabric, is composed of directional or random fibers, and has the characteristics of moisture-proof, breathable, flexible, light, easy to decompose, non-toxic, and non-irritating. The use of melt-blown method to make melt-blown non-woven fabric is a new promising new technology, which has the advantages of advanced technology, short process and low cost. Especially...
