Surface modification of Polyester is well known method to scour the Polyester. Among the various factors of the primary treatment conditions, the research reports have underlined the role of temperature and presence of catalyst. In this study an attempt has been made to examine the effects of Pick spacing along with the primary treatment conditions. The starting materials were 100% Polyester woven on a power loom in the laboratory. The fabric was subjected to alkaline hydrolysis and tested for various properties. The first part of this paper discusses the effect of concentration of NaoH on % shrinkage, weight loss and bending length of polyester fabrics. The results show the sensitiveness of the fabric to primary treatment conditions and the pick spacing as revealed by the properties.
