Analysis of four methods of textile abrasion testing

Many products will have certain losses due to handling collision or friction. After a long time, they will fade, blur patterns, and surface wear. Therefore, it is necessary to conduct abrasion testing to understand the abrasion performance of the product and obtain information on reliability such as product wear resistance. Manufacturers can improve product materials or designs based on this information.

Shanghai Qianshi Precision Electromechanical Technology Co., Ltd. was established in 2012. It focuses on the research, development, design, and production of textile testing instruments, and provides textile testing instruments and services for academic research units and testing institutions. Shanghai Qianshi is currently one of the most competitive R&D textile testing instrument manufacturers in China. The R&D team is composed of a group of experienced engineers. We are committed to serving customers wholeheartedly and striving to promote technological innovation in textile testing instruments.
