Easily alkali soluble polyester and method for producing the same |
| abstract |
The present invention discloses an easily alkali soluble polyester comprising at least one dicarboxylic acid or monoesters thereof or diesters thereof; at least one diol; at least one carboxylic acid anhydride; at least one sodium or lithium based aromatic co-monomer and at least one hydroxyl terminated polyester polyol. The polyester is produced by esterifying at least one dicarboxylic acid or monoesters thereof or diesters thereof and at least one diol alongwith at least one acid anhydride at a temperature in the range of 250 to 290° C and pressure in the range of 0 to 5 kg/cm2g; and polycondensing the esterified mixture along with at least one sodium or lithium based aromatic compound and at least one hydroxyl terminated polyether polyol at temperature in the range of 250 to 290° C and under vacuum of 0.1 to 10 torr. The invention further discloses bicomponent filament yarns or staple fibers comprising the above easily alkali soluble polyester as one polymer component and any filament or fiber forming polymer as a second polymer component and process for producing the same. |
