中文摘要：为研究脂肪族酯类单体分子结构对脂肪族-芳香族水溶性共聚酯浆料上浆性能的影响,选取具有不同碳链长度的脂肪族二羧酸酯(ADE)单体,以酯交换-缩聚法合成出一系列具有不同酯基结构的水溶性共聚酯,再通过与酸解淀粉共混对涤/棉(65/35)经纱进行上浆实验,测试了浆纱的强伸性、耐磨性及毛羽数量。结果表明:ADE单体的碳链长度对水溶性共聚酯浆料的浆纱性能有着明显的影响,以丙二酸二醇酯为ADE单体合成出的共聚酯浆料具有较为优异的上浆性能,与原纱相比,以此单体合成出的共聚酯与淀粉浆料共混时,浆纱的断裂强度提高了45.72%,断裂伸长率仅降低了11.73%,耐磨次数达到原纱的近2倍,毛羽数量大为降低,生物可降解性能亦比纯芳香族聚酯有较大改善。

外文摘要：In order to study the influence of molecular structure of aliphatic dicarboxylate ester（ ADE）monomers on sizing properties of aliphatic-aromatic water-soluble copolyesters,ADE monomers with various carbon chain lengths were chosen to prepare aliphatic-aromatic water-soluble copolyesters with different ester structures by transesterification-polycondensation. Then the copolyesters were blended with hydrolyzed starch to size polyester / cotton（ 65 /35） warp yarns. The performance of the sized yarns was evaluated in terms of tensile strength,elongation,abrasion-resistance and the amount of hairiness. The results show that carbon chain length of ADE monomers has great effect on sizing properties of watersoluble copolyesters. The copolyester synthesized by dimethyl malonate（ DMM） as aliphatic monomers exhibits better sizing properties than the other water-soluble polyesters. Compared with unsized yarns,the yarns sized by hydrolyzed starch the copolyester synthesized by DMM has tensile strength increased by45. 72% while the tensile elongation is decreased by only 11. 73%. The abrasion number of the sized yarns is almost doubled and the hairiness amount of the yarns is decreased to a large extent. In addition,the biodegradability of the copolyester synthesized by DMM is much better than that of pure aromatic water-soluble polyester.
