Research of technological parameters and physical and mechanical properties of double-layer knitwear

The article presents the results of an analysis of the technological parameters and the physic mechanical properties of new variants of the structures of double-layer knitwear worked out on a long-plane flat-wing machine. In order to reduce the consumption of raw materials, improve the quality of knitwear and expand the technological capabilities of the Long Xing flat-plate machine and the range of knitted fabrics, a method for producing double-layer knitted fabrics on a flat-plate machine has been developed. An analysis of the results of the study shows that the structure of double-layer knitwear helps to reduce bulk density, increase the strength of knitwear in length and width, reduce the elongation and shrinkage of knitwear, which improves shape stability, which positively affects the consumer properties of the developed samples of doublelayer knitwear.
