Effects of monomer compatibility of aliphatic/aromatic dicarboxylic ester on sizing performance of water-soluble copolyester
摘要
Abstract
The effects of monomer compatibility of dimethyl malonate (DMM) and dimethyl terephthalate (DMT) on sizing performance of environment friendly water- soluble aliphatic/aromatic copolyesters (WSACP) were surveyed. Through blending DMM/DMT monomers with various molar ratios, a series of environment friendly WSACP with different molecular structures were prepared using a two- step method (i.e. transesterifi?cation- polycondensation). Viscosity average molecular weight, COD & BOD values and contact angles on T/C blended fabric of the WSACP sizes, as wel as apparent viscosity of WSACP/starch blended sizing paste were evaluated initial y. Then the copolyesters were blended with starch sizes and the blends were employed to size T/C 65/35 warp yarns. Tensile strength, tensile elongation, abrasion resistance and hairiness of the sized yarns were tested. The experiment results showed that when the molar ratio of DMM and DMT was 3/7, the sized T/C blended yarns exhibited better sizing performance.关键词
