聚酯

In home, due to the shortage of polyester glycol, one of raw materials of preparing water-borne polyurethane, aromatic polyester glycols having designed molecular weight of 600,1000 and 2000 are synthesized in lab.

由于国内缺乏制备水性聚氨酯的原料聚酯二醇，实验自制了设计分子量为600、1000和2000的芳香族聚酯二醇；其中以邻苯二甲酸酐、间苯二甲酸、对苯二甲酸为二元酸，乙二醇、1，3—丙二醇和新戊二醇等为二元醇。

The result which was gained through experiments shows that the transverse tensile brute force of short-fiber non-woven fabric composite is higher than that of long-fiber non-woven fabric composite, but the transverse tearing brute force is lower than that of long-fiber non-woven fabric composite when the thickness of two kind of non-woven fabric composite are the same.

经实验发现，同种厚度短纤非织造布基布的横向拉伸性能优于长纤的，横向撕裂强力次于长纤的。聚酯非织造布基布的横向拉伸强力优于聚酯和尼龙混纤非织造布基布的，而横向撕裂强力两者均较差。确定热敏凝胶体系并研究其对基布横向力学性能的影响。
