Production of high-strength polyester abrasive cloth

Abstract

A process for preparing high-strength polyester-type abrasive cloth features that its substrate cloth is pretreated by high-tension stretching and hot shape-fixating and finishing. Its apparatus has additionally two high-tension stretching unit, a group of 10 high-temp ironing drums and a baking room at 190-210 deg.C.

Description

Technical field: [0001] The invention relates to a method for manufacturing abrasive cloth, in particular to a method for manufacturing high-strength abrasive cloth. Background technique: [0002] A large number of cotton fiber materials are used in abrasive cloth products produced by my country's abrasive tool manufacturing industry, which not only has limited uses, but also wastes a lot of land resources. Therefore, it is necessary to use synthetic fiber materials instead of cotton fibers to produce multi-performance and multi-variety grinding products The top priority of my country's abrasive tool manufacturing enterprises, and polyester fiber is the synthetic fiber material with the largest output, the widest application and the lowest price in the world. Compared with cotton fiber, it has higher mechanical tensile strength. The strong abrasive cloth products made can extend the use to high-strength grinding of large parts, and are not easy to break, and are safer and more...

Problems solved by technology

[0002] A large number of cotton fiber materials are used in abrasive cloth products produced by my country's abrasive tool manufacturing industry, which not only has limited uses, but also wastes a lot of land resources. Therefore, it is necessary to use synthetic fiber materials instead of cotton fibers to produce multi-performance and multi-variety grinding products The top priority of my country's abrasive tool manufacturing enterprises, and polyester fiber is the synthetic fiber material with the largest output, the widest application and the lowest price in the world. Compared with cotton fiber, it has higher mechanical tensile strength. The strong abrasive cloth products made can extend the use to high-strength grinding of large parts, and are not easy to break, and are safer and more reliable to use. At present, some domestic enterprises have gradually begun to realize the development prospects of polyester cloth strong abrasive cloth, but due to lack of relevant The special equipment and technology for polyester cloth pre-treatment and post-finishing are only suitable for making some blended cloth abrasive belt products, and the product quality is very unstable

The problem is mainly reflected in the fact that when polyester blended fabric is used to manufacture strong abrasive cloth, the equipment conditions and process conditions originally used to produce cotton cloth abrasive cloth cannot eliminate the high extensibility of polyester fiber and maintain dimensional stability. It is very easy to deform and make the abrasive cloth unusable, so the development and production of high-strength polyester abrasive cloth with high flatness and high stability has a very broad market prospect
