Introduction: During warp calculation in weaving, the following formula will be found useful for determining various particulars required in practice. In this article we will discuss warp calculation formulas in weaving with problems, solutions, and examples They have all been derived from the fundamental formula, Count = Number of hanks per lb. Different Formulas of Warp…
Yarn diameter: The cross-section of cotton yarn is more or less circular. Therefore, as the count of cotton yarn is equal to the number of length unit per weight unit it can be shown that for practical purposes, the diameter of yarns is approximately inversely proportional to the square root of the counts. In this…
Production of Loom: The production of a loom mainly depends on the speed of the loom. Higher speed does not always mean higher production because if it exceeds a certain limit, loom stoppages due to excessive warp breakages occurring. As a result of higher speed may even reduce the production to a considerable extent. Other…
Sizing: Sizing is a complementary operation that is carried out on warps formed by spun yarns with insufficient tenacity or by continuous filament yarns with zero twists. In general, when sizing is necessary, the yarn is beam warped, therefore all beams corresponding to the beams are fed, as soon as warping is completed, to the…
Counting of reed count: Reed determines the spacing of warp threads. Ordinary reed used for weaving cotton fabrics is made of rustless steel wires. They are bound at each end on balks by pith bands, whose thickness determines the spacing of dents. Sometimes brass wires are used instead of rustless steel. In this article, counting…
Warping: Warping is defined as the parallel winding of yarn from a cone or cheese package onto a warp beam. The operation of winding warp yarns onto a beam usually in preparation for slashing, weaving, or warp knitting. Also called warping. In this article, we will discuss different formulas of warping calculation with examples. Different…
