Abstract

The invention discloses a nonwoven fabric, made with the following materials according to parts by weight: 70-80 parts of PET (polyethylene terephthalate), 15-20 parts of PLA (polylactic acid), 5-10 parts of an antibacterial agent, 10-15 parts of acrylic adhesive, and 1-2 parts of diatomaceous earth; diatomaceous earth particles are fine and porous and can improve filtering precision of the nonwoven fabric, microorganisms such as Escherichia coli are filtered, direct filtration under non-uniform fiber pore size of the nonwoven fabric is avoided, filtering effect of the nonwoven fabric is guaranteed, the antibacterial agent can inhibit reproduction of the microorganisms such as bacteria, antibacterial capacity of the nonwoven fabric is improved, and therefore the produced nonwoven fabric has good antibacterial performance and high filtering precision. The invention also discloses a production process and application of the nonwoven fabric.

Description

technical field [0001] The invention relates to a fabric, in particular to a non-woven fabric and its production process and application. Background technique [0002] Non-woven fabric is a kind of fabric formed without spinning and weaving. It is just oriented or random arrangement of short textile fibers or filaments to form a web structure, which is then reinforced by mechanical, thermal bonding or chemical methods. [0003] At present, the Chinese patent with the publication number CN102575396B discloses a needle-punched nonwoven fabric, which is made of at least two short fibers of the same type or different types with low melting point and high melting point respectively. The hardness of the nonwoven fabric is It is sufficient that the nonwoven fabric is self-supporting, has shape retention, and can be pleated, and the nonwoven fabric also has very excellent moldability and compressive strength. [0004] However, the antibacterial performance of the non-woven fabric i...
