Stretch characteristics of fillet warp knit with elastomeric in-layed yarn

Abstract

This paper presents results of an investigation on the stretch characteristics (full strain and its parts) of fillet warp knitted fabric with elastomeric yarn longwise inlaying. In order to undertake the study of the influence of in-layed yarn positioning and of fillet interloping repeat different types of fillet warp knit fabrics with in-lay yarn were produced. The array of data for the various design options provide analytical tool for making comparisons about the mechanical properties of the warp knit fillet structures with elastomeric inlayed yarn. It is observed that the repeat of fillet interloping and the position of in-laying yarn have some effect on stretch characteristics of warp knit structures. It is a consequence of a different relaxation of inlayed yarn in structure. Elastic strain is the largest part of the full strain of warp knit fabric and the part of residual strain does not exceed 0.11.
