| titleOfInvention | It is a kind of for the hydrophilic production method for leading wet polyester staple fiber of Direct Spinning |
| abstract | The present invention provides a kind of for the hydrophilic production method for leading wet polyester staple fiber of Direct Spinning, it include: that (1) mixes terephthalic acid (TPA) with ethylene glycol, prepolymerization reaction is carried out, gained prepolymer obtains hydrophilic modifying copolyesters melt after terminal polymerization kettle polycondensation；(2) melt is fed directly to spinning manifold, after profile spinneret squeezes out, is made hydrophilic and leads wet polyester staple fiber.The present invention will be by that will have hygroscopic reactive functionality to be introduced into based on PET in the polyester system of structure, process aoxidizes heat stabilizer using titanium catalyst and compound a heatable brick bed, polyethers hydrophilic modifier is added in precondensation stage simultaneously, reduce residence time of the polyethers in kettle, it avoids polyethers from degrading, and reduces the dry step of polyester slice, further decrease poly- ether bond rupture, a possibility that polyester is degraded, can be prepared the fiber of excellent in mechanical performance with lower intrinsic viscosity. |
