The investigation of the loop length of elastic warp knitted fabric

Abstract

The loop length is the main parameter of the knitted structure, that affect the fabrics density and its basic weight as well as air permeability, strength, elasticity, and other properties. It affects also extensibility, width and length of product and, therefore, a whole appearance of the item. The study of the influence of knitting technological parameters on the loop length of elastic warp knitted fabric for the rehabilitation and preventional goods manufacture is the purpose of this research. The three-factor experiment has been planned and carried out during this study. The linear density of the weft filling-in yarn, the pre-elongation of an elastomeric thread and the tension of ground yarn were chosen as input factors. The regression equations that adequately describe the dependencies of the loop length on these technological parameters have been established.

Dužina petlje je osnovni parametar pletene strukture, koja utiče na gustinu tkanine i njenu osnovnu težinu, kao i propusnost vazduha, čvrstoću, elastičnost i druge osobine. To utiče i na rastegljivost, širinu i dužinu proizvoda i, samim tim, na čitav izgled predmeta. Svrha ovog istraživanja je proučavanje uticaja tehnoloških parametara pletenja na dužinu petlje elastičnog osnovnog pletiva za proizvodnju sanacione i preventivne robe. Eksperiment sa tri faktora je planiran i sproveden tokom ove studije. Kao ulazni faktori izabrane su linearne gustine prediva za popunjavanje potke, predizduženje elastomernog konca i zatezanje prediva. Utvrđene su regresione jednačine koje adekvatno opisuju zavisnosti dužine petlje od ovih tehnoloških parametara.
