IN THIS VIDEO I AM EXPLAINING SIZING CALCULATIONS THAT ARE REQUIRED TO MAKE A SIZED BEAM. When we apply a thin film of starch and binders on the yarn surface, the yarn twist gets permanent. Thus sizing process makes a single-ply yarn weavable. The main objectives of sizing are given below: 1- To improve the weavability of the yarn. 2- To improve the strength of warp yarn. 3- To improve the degree of hairiness of warp yarn. 4- To optimise the abrasion resistance of yarn. Stretch % : it is the ratio of the difference between sized warp length and warp length before sizing to warp length before sizing expressed in the term of percentage. Please note, the stretch% should be as minimum as possible. WARP COVER IN SIZING: The ratio of space occupied by yarn to total space occupied by warp sheet expressed in the term of percentage is called warp cover in sizing R f % or size concentration%: The size liquor concentration is measured by refractometer so that it is also called refractometer value in terms of %. The size liquor concentration is the ratio of solid contents to the total volume of liquor after cooking expressed in terms of percentage is called size liquor concentration% or RF %.
