Properties of PA/cotton yarns enhanced by the sizing process

Yarn sizing represents the most complex phase in the fabric production, due to the necessary multidisciplinary approach to the whole process, with the aim of achieving improvement in the yarn physical-mechanical parameters relevant for the further weaving process. Changes of the sizing parameters, of both, the sizing plant and the sizing conditions, greatly influence the sized yarn properties. This research deals with type of yarn (PA 6.6 / cotton) that are characterized by their abrasion resistance but at the same time by their durability, comfort, lightweight and strength. Despite these remarkable properties, subjecting these yarns to the sizing process enhance their properties relevant for further technological processes of fabrication in order to achieve maximum effects. This research shows the extent to which the sizing process influences the improvement of tested yarns properties and analyse the impact of various size mass concentrations and different sizing processes. The complete analysis is considered in the context of sizing process optimization and overall justification and acceptability.
