Loom parameters play a significant role in producing fabrics from finer yarns. It is always difficult to weave cloths especially with finer yarns controlled by asymmetric cam motion. That is why showing the effect of cam asymmetry on the formation of woven fabrics and finding out an optimum setting of the loom parameters to produce the …
Weaving is a method to produce fabrics by the right angle interlacement of 2 sets of yarn –named as warp [longitudinal direction or length-wise direction] and weft [transverse direction or width-wise direction]. In this article, A-Z of producing the woven fabrics from swatch to the finished fabric delivery has been precisely outlined. Let’s see how …
Knitting is one of the most used fabric production techniques, where yarns are interlooped to form the flat fabric. Two types of knitting exist, namely, warp knitting and weft knitting. A weft-knitted fabric can be produced using one single strand of yarn Figure-1(a). while a warp-knitted fabric or a woven fabric requires the same number …
Statement: “the force needed to extend or compress a spring by some distance is proportional to that distance.” and this can be written as: F = -kx …………………………(1) Where F is the force, x is the length of extension/compression and k is a constant of proportionality known as the spring constant which is usually given …
Yarn pull-out measurements reveal information on the interactions among the yarns of the fabrics, mainly on the friction between yarns. In the yarn pull-out method, the fabric is held by fixed jaws on both sides. A certain number of yarns in the form of fringe on the upper part of the fabric are formed and …
To understand the fabric behaviour under tensile load, a generalized load–elongation behaviour of woven fabric is shown in figure 2. The curve consists of three distinct regions. Initial (OA) dominated by frictional restraint, followed by AB (decrimping region) and, finally, BC leading to yarn extension. Region 1 (OA): The initial part of the curve, is …
