摘　　要：为研究水溶性聚酯浆料的酯基结构对其上浆性能的影响并探索聚酯浆料对纯涤纶经纱的上浆配方,选取不同的二醇类单体,合成出2类具有不同酯基结构的水溶性聚酯浆料,再通过与酸解淀粉共混进行上浆实验。结果表明:水溶性聚酯浆料酯基的化学结构对其上浆性能影响显著,以乙二醇为酯基结构单元的聚酯浆料有利于改善其使用性能;在淀粉浆料中加入水溶性聚酯可以显著提高对涤纶经纱的浆纱性能,其用量为20%时浆纱性能较好。In order to study the effect of ester structure of water-soluble polyester（WSP） sizes on sizing properties of polyester warp yarns and investigate the size recipe of WSP sizes,two kinds of WSP sizes with different ester structures were synthesized through choosing different diol monomers and a series of sizing experiments was carried out on pure polyester warp yarns with WSP size blended with acidified starch.The results show that ester chemical structure of WSP sizes has great effect on sizing properties,and the sizing properties of blended size are remarkably improved if WSP size taking glycol as ester structure unit is employed.Moreover,the properties of starch sizes for pure polyester warp yarns are obviously improved if WSP sizes are properly used and the weight percentage of WSP to the blended size is 20%.
