There are two ways of fabric weight calculation. One is the weight per unit area such as GSM (grams per square meter) or oz / yd2 and another way is weight in running length. Fabric Weight Calculation from Running Length: Calculate the GSM of the following technical textile fabric, …120 x 70 ……………………… x 58 … Read more
Introduction: Shedding is the first primary motion of the loom motions. Dividing of warp threads into two parts for insertion of weft thread is called shed, and the mechanism to form shed is called shedding.

Introduction The process of applying a protective adhesive (PVC, CMC, PVA etc.) coating upon the yarn (warp) surface is called sizing. This is the most important operation to attain maximum weaving efficiency specially for blended and filament yarns. Due to sizing increases elasticity of yarn, yarn strength, smoothness, weight of the yarn and frictional resistance … Read more
Introduction Ring Frame is the last and most important machine in a spinning mill where the final draft is applied on roving and converted to yarn with the required count, i.e., the final yarn with desired count gets spun on the Ring Frame machine. Actually, Ring spinning is a method of producing yarn from fibers … Read more
Introduction Combing is the removing process of short fibers, neps & impurities of carded sliver and to make the fiber more parallel, uniform & straight by using a comb machine or comb associated by knives, brushes and rollers. Combing is necessary for better yarn appearance and regularity. Longer fibers are finer than shorter fibers. After … Read more
Introduction Roving Frame or Speed Frame or Simplex is the machine of a spinning mill, where the sliver is subjected to one or more attenuating process and the attenuated sliver receives a small amount of twist and is then wound on bobbins. The output product of speed frame machine is called Roving. So it is … Read more
