Problems solved by technology

[0006] The main technical problem to be solved by the present invention is to solve the defects that most of the current non-woven fabrics are made of insulating materials, which are easy to fluff after a certain period of time, and are more likely to generate static electricity due to friction, which makes it difficult to release static electricity stored in non-woven fabrics.

Abstract

The invention discloses a preparation method of an antistatic non-woven fabric, and belongs to the technical field of textile preparation. Polypyrrole is formed from pyrrole by initiating of cationicradical polymerization in a conductive mixed solution and an oxidation initiating solution, and reaction on the surface of a PET spunlace substrate and a mixed solution to improve the antistatic property of the nonwoven fabric; in the oxidation initiating solution, sulfosalicylic acid and ferric nitrate are mixed to form an aqueous solution of the sulfosalicylic acid and the ferric nitrate, and the sulfosalicylic acid is chelated with iron ions to promote stable redox reaction, so that the polypyrrole is uniformly deposited and distributed on the surface of a composite material of the PET spunlace substrate and PVA-co-PE nanofiber, after a modified non-woven fabric is immersed in the suspension of the PVA-co-PE nanofiber, the surface of the modified non-woven fabric is coated with a layerof the PVA-co-PE nanofiber, the specific surface area of the composite material is increased, the mass per unit area of the polypyrrole allowed to be the adsorbed and contained can be more, hole transferring efficiency is higher, the antistatic property of the nonwoven fabric is improved, and the application prospect is broad.

Description

technical field [0001] The invention discloses a method for preparing an antistatic nonwoven fabric, which belongs to the technical field of textile preparation. Background technique [0002] Non-woven fabrics, also known as non-woven fabrics, are composed of oriented or random fibers. It is called cloth because of its appearance and certain properties. Polypropylene pellets are mostly used as raw materials, which are produced by continuous one-step process of high-temperature melting, spinning, laying, and hot-pressing coiling. Non-woven fabrics have no warp and weft threads, are very convenient for cutting and sewing, and are light in weight and easy to shape, so they are deeply loved by handicraft lovers. [0003] According to the composition of non-woven fabrics, there are polyester, polypropylene, nylon, spandex, acrylic, etc.; different compositions will have completely different styles of non-woven fabrics. The spunbond fabric usually refers to polyester spunbond a...
