| titleOfInvention | Preparation method of cation-dyeable regenerated polyester fiber and product thereof |
| abstract | The invention discloses a preparation method of cation dyeable regenerated polyester fiber and a product thereof, which comprises the steps of respectively pre-crystallizing and drying regenerated polyester and crystalline sulfonate copolymer master batches, mixing, carrying out double-screw melt blending, conveying to a spinning position for melt spinning, and preparing the cation dyeable regenerated polyester fiber; the crystalline sulfonate copolymerization master batch is prepared by carrying out esterification reaction on dihydric alcohol and dibasic acid, introducing sodium dihydroxy ethyl isophthalate as a third monomer, long-carbon-chain polyethylene glycol as a fourth monomer, and simultaneously introducing inorganic nucleating agent powder for polycondensation. The invention solves the problem of difficult copolymerization of high proportion modified components, and promotes the high proportion copolymerization of the third monomer, the fourth monomer and the polyester ester; meanwhile, the crystallinity of the master batch is promoted, and the master batch particles are prevented from being bonded and are sufficiently dehumidified. |
