Abstract

The effect of CPI starch on basic yarn mechanical properties that are critical to weavability was evaluated and compared to a commercial starch and polyvinyl alcohol (PVA). Size penetration, tensile strength, elongation, and bending flexibility of sized yarns were examined. Desizing, add-on, and abrasion properties of the starch were tested. The CPI starch exhibited greater stiffening of yarns than the commercial starch and stiffening that was very close to PVA. The CPI starch also had excellent performance of forming starch film round yarn surface and less penetration into fiber bundle of the yarn. CPI starch exhibited less impairment of yarn extensibility and compressibility of sized yarns and improved yarn surface properties.
