Antistatic composite non-woven fabric

Abstract

The invention relates to an antistatic composite non-woven fabric, which comprises a first non-woven fabric layer, a second non-woven fabric layer, a wear-resistant layer, an antistatic layer, a tear-resistant layer and supporting threads, wherein the wear-resistant layer is arranged between the first non-woven fabric layer and the antistatic layer, the tear-resistant layer is arranged between thesecond non-woven fabric layer and the antistatic layer, the antistatic layer is arranged between the wear-resistant layer and the tear-resistant layer, the supporting threads are arranged between thefirst non-woven fabric layer and the second non-woven fabric layer, the antistatic layer is formed by thermoplastic polyurethane filled with natural rubber and acetylene carbon black, and the supporting threads are glass fiber silk threads. According to the invention, the antistatic composite non-woven fabric is simple in structure; the antistatic effect can be effectively achieved by utilizing the antistatic layer made of polyurethane, so that the quality of an electronic precision instrument is protected; and the tensile strength, the bending strength, the toughness and the stability of thenon-woven fabric can be effectively improved through the additionally-arranged tear-resistant layer and the supporting threads, so that the service life of the non-woven fabric is prolonged, the functions are diversified, the application range of the non-woven fabric is enlarged, and the non-woven fabric can be widely applied and popularized.

Description

technical field [0001] The invention belongs to the technical field of nonwoven fabrics, and in particular relates to an antistatic composite nonwoven fabric. Background technique [0002] Now the non-woven fabric on the market is also called non-woven fabric. Although it is cloth, it is not woven, so it is called non-woven fabric. The existing non-woven fabric has a wide range of applications, such as breathable, tear-resistant, radiation-resistant, etc. And so on, there are many kinds and all kinds, but the non-woven fabrics on the market currently have relatively single functions, relatively large limitations, and relatively small scope of use, especially for fabrics on some electronic precision instruments. , the antistatic requirements for non-woven fabrics are relatively high, and if the antistatic effect is not achieved, it is easy to damage the quality of electronic precision instruments during use, affect the accuracy of the instrument, and even need to replace the ...
