The influence of weft filling yarn on the properties of warp knitted fabric

Abstract

An important issue for people today is to extend the solutions to health problems, including treatment and prevention of spine diseases. This increases the need for support and fixing of different spine parts, that promotes the demand growth of the binders and braces. Such special goods prevent the emergence and stop the disease development, improves the well-being condition and normal function of the body, the ability to maintain performance and activity. Despite the huge number of existing structures of therapeutic and prophylactic products, the elastic fabrics of different width are the basic materials for their manufacture. Therefore, the main attention is directed to the formation and investigation of the knitted elastic fabric for special purposes, especially for preventive goods The knitted fabrics with weft - inserted yarn that produced on crochet knitting machine is the subject of this research. The chain is the basic interlooping of all variants. An elastomeric thread is introduced into the structure as longwise inlaying yarn with preliminary elongation to ensure the necessary extensibility of knitted structure. The weft filling yarn is laid on both sides of the elastomeric threads to prevent its contact with the body and to ensure the hygienic properties of medical goods. The few variants of weft yarn filling have been used: at the whole width of fabric that create a smooth surface and according to the repeats as well. The studies of fabrics properties were carried out at this research. The influence of inlaying variants of weft yarn on structure parameters and mechanical properties was found.
