| titleOfInvention | A kind of cationic fiber can contaminate the preparation method of artificial leather |
| abstract | The present invention relates to the preparation methods that a kind of cationic fiber can contaminate artificial leather,, the following steps are included: diglycol terephthalate oligomer is transferred in polymerization reaction kettle by (a), addition polycondensation catalyst, 5-sodium sulfo isophthalate, polyethylene glycol and surfactant carry out reacting obtained modified poly ester for it；It (b) is that sea component by two-component spinning equipment prepares figured sea-island staple fiber using the modified poly ester as island component, alkali solubility polyethylene terephthalate；(c) it by the figured sea-island staple fiber lapping, then through needing machine obvolvent processes to form non-woven fabrics；(d) to non-woven fabrics carry out macromolecular elastomer pad, alkali process, sanding, dyeing and arrangement.Initial stage pressure when melt spinning can be reduced in this way, filtering pressure is inhibited to rise, the fiber with excellent cation-dyeable performance is made, so that artificial leather has gay colours. |
