This invention relates to polyester materials. The extracted aqueous soluble polyester paste comprises terephthalic acid and some other dicarboxylic acids, glycol and some other diols, some inorganic salt additives and at least two species of polyglycol with a structural formula shown below: H-(OCH2CH2)n-OH where n is not less than 2 and not more than 4 or not less than 45 and not more than 136. The method to prepare aqueous soluble polyester paste is direct esterification polycondensation during which modification ingredients including sulphonate, inorganic salts and polyglycol are added so that products are eligible for the requirements of sizing production in spinning. The aqueous soluble polyester not only performs good adhesion to dacron yarns and good miscibility to starch and other polymer paste, but also has the advantages of environmental friendliness and easy de-sizing. |
