Overview

This course Basic Textile calculation is related to all basic calculations used in textile industry ie spinning & weaving. The content includes all conversions of units, yarn count system, conversion formulas for yarn counts, calculations in warping, sizing & weaving. This course is helpful for students & working professionals.Yarn count system includes Direct, Indirect & Tex count system with examples for better understanding. Conversion of count from one system to other, count of plied yarn etc. Weaving& fabric calcuations part covers most of useful formulas required for warping calculation, yarn requirement calculations, sizing calculations & production calculations of weaving.COUNT of yarn is numeric expression, which defines its fineness.1. Indirect system- Fixed Weight SystemIn this system Count is no. Of units of length per unit weight of yarn.2. Direct system - Fixed Length SystemIn this system Count is no. of units of weight per unit length of yarn.3. Universal System -Ø TEX is universal system.Ø It is Direct system introduced by ISO.Ø Useful for natural as well as synthetic fibers.Ø Used for fiber to yarnØ Finess of fiber is expressed in militex - Wt. Of fiber in mg in one km lengthØ Fineness of ropes, cords & twines expressed in kilotex.Count of Folded / Plied yarns: Single yarns are made into ply by twisting in order to increase strength. Count of folded yarns is indicating size is preceded by no. Indicating ply or strand of which the yarn is composed.Direct Warping; Sectional warping; DBF; No of sections, width of section, weight requirement of dyed yarn.Sizing: Yarn weight cal, size pick up%, costing calculations.Weaving - Loom production, Reed, CMPX - Warp/weft breakages per centi million picks.
