Piezoelectric bending actuator for textile industry

The warp knitting industry is one of the fastest growing industries in my country's textile industry. Modern warp knitting equipment is constantly developing in the direction of high-speed production, intelligent control, diversified functions, easy operation, and computerized design. The structure of warp knitting products has gradually become more reasonable, with the coordinated development of three categories of products for clothing, decoration, and industrial use, and the application of products has been continuously expanded. These will undoubtedly promote the warp knitting industry to develop in a sustainable, healthy and steady direction. Since this century, the warp knitting industry has entered a period of steady and rapid growth. Modern warp knitting technology has been developed rapidly due to its high production efficiency, product fancy diversity, and flexibility of fabric structure. The industrial scale has expanded rapidly, and it has occupied an important position in the textile industry. Compared with the traditional Jacquard technology, the piezoelectric ceramic Jacquard technology does not have the shifting needle and the Jacquard yarn guide needle to coordinate with the lateral movement, the structure is simpler, and the operation and maintenance are more convenient. The piezoelectric ceramic Jacquard element is controlled by current pulses. Offset one stitch length to realize high-frequency needle selection and meet the needs of high-speed production.
