Abstract

The purpose of the article is to introduce the method of making double-layer knitwear with reduced material consumption. A decrease in the material consumption of knitwear can be achieved by: excluding a part of the needles from the looping process; knitting wth incomplete weaves; the inclusion of press loops into the knit structure. A method has been developed for producing a double-layer knitwear with reduced material consumption. The new method is simple to implement, does not require changes in the design of the flat-fang machine. In order to expand the range of knitted fabrics and to study the effect of press loops in the structure of a double-layer knit on its parameters and physicomechanical properties, 5-variants of a double-layer knit were developed, which differed from each other in structure. Comparison of pressed, jacquard and incomplete weave knitwear among themselves by surface density showed that the knitwear of incomplete weaves has the smallest surface density, while comparison of the samples by bulk density showed that the pressed weave knitwear has the lowest density, because the thickness of the press knitwear is greater than that of the other weaves. The change in the structure of the layers of double-layer knit affects not only its parameters, but also the physicomechanical properties of the knit. The variants with the lowest material consumption, high strength and the highest dimensional stability are determined. The best variants of double-layer knitwear are recommended for the manufacture of knitwear for adults and children’s assortment. Comparison of samples of double-layer knitwear with each other by bulk density showed that when improving developed double-layer knitted fabrics, the reduction in raw material consumption reaches 7–15% compared to the base weave.
