| titleOfInvention | A kind of preparation method of porous easy dyeing spandex |
| abstract | The present invention relates to a kind of preparation method of porous easy dyeing spandex, the method is at the first reactor 1 st In Reactor, add polytetramethylene ether diol PTMG, 4 simultaneously, 4-'-diphenylmethane diisocyanate 4,4-MDI, fully carries out prepolymerization reaction, obtains the prepolymer PP with-NCO end-blocking; In high speed dissolving machine Dissolver, adopt DMA DMAC as solvent, to prepolymer, PP fully dissolves, the pre-polymer solution PPs of contained-NCO end-blocking; At the second reactor 2 nd In Reactor, adopt the mixed amine DMAC solution that contains Diamines chain extender, monoamine terminator and hydramine to carry out chain growth, chain termination to PPs simultaneously, prepare end with-OH polyurea based formic acid esters solution; Then, add antioxidant, lubricant, delustering agent, ultraviolet absorber and polyvinylpyrrolidone PVP, dispersed with stirring; Finally, by dry spinning system, the polyurea based formic acid esters solution that contains auxiliary agent is sprayed to silk a stretching, high temperature drying, finish oil, coiling and molding, just obtain easy pore, chromatophilia can spandex. |
