摘要/Abstract

摘要：

以对苯二甲酸（PTA）、乙二醇（EG）、间苯二甲酸（IPA）、聚乙二醇（PEG）为单体合成了一种新型分散染料常压可染聚酯（NEDDP），其Tg低于60℃，Tcc为120℃，Tm为252℃。以NEDDP为岛组分，易水解聚酯（EHDPET）为海组分纺制的海岛型复合纤维，用稀碱溶液水解剥离制备NEDDP超细纤维时，岛组分不会被刻蚀。0.06dtexNEDDP超细纤维织物可在100℃下染成中深色，在120℃下染成黑色或深棕色。NEDDP也可纺制多种规格1.0~1.5dtex的POY-DTY及FDY，该NEDDP纤维织物可以在100℃下染成黑色。NEDDP纤维织物具有优良的染色牢度。与以往的PET纤维织物在130℃染色相比较，可节省能量30%，染中深色时可节约染料20%左右，可缩短染色时间25%，提高了劳动生产率。

Abstract:

A new easy disperse dyeable polyester (NEDDP) which can be dyed under atmospheric pressure has been synthesized by PTA, EG, IPA, PEG. Tg of NEDDP is below than 60℃, Tcc is about 120℃ and Tm is about 252℃. NEDDP as island component and easy hydrolysis degradation polyester（EHDPET）as sea component, Sea-Island composite fibers can be obtained. Further NEDDP super fine fibers formed hydrolysis with sparse alkali solution. And during hydrolysis course island component wasn’t damaged i. Fabric made of NEDDP super fine fibers (0.06dtex ) can be dyed to Medium depth at 100℃ and deep black at 120℃. Several NEDDP’s POY, DTY and FDY (1.0~1.5dex) produced, and these fabrics can be dyed black colour at 100℃and have same fastness with common PET fabrics dyed at 130℃, the energy cest can be saved by 30% if NEDDP fabrics dyed the same color. When dying close to deep color, the energy cost can be saved by 20% and dyeing time can be shorten by 25%.

Key words: easy desperse dyeable polyeser, sea-island compound fiber, energy conservation, glass transition temperature
