Abstract

Sizing imparts the strength and increases the abrasion resistance of warp yarn in a weave-shed. Various methods were established for characterizing size films and sized yarns to establish relationships that might be useful in predicting weaving performance. A variety of natural and synthetic binders were applied to cotton yarn in a laboratory sizing apparatus, equipments and other available sources. There are two critical factors to evaluate size material performance are : Size must from a tough but flexible film to protect the yarn from stress , strain and rubbing actions , and there must be good adhesion between size and yarn. The flexibility i.e. extensibility is correlated with tensile properties of films. The degree of adhesion was evaluated by Lap-joint test in this study. Presence of starch percentage even after desizing was determined on Tegewa scales, important for environmental concerns [4, 7].
