SIPM/DMSIP/third monomer
Uses: The product is a white powder , soluble in water and alcohol. As the most used dyeing property modifier of polyesters, it is mainly used to improve the dyeing properties of polyesters, but can also be used as the intermediate in the synthesis of organic agents, large molecules and find chemicals.
Dimethyl-5-Sulfoisophathalate Sodium salt(DMSIP, CAS:3965-55-7) is mainly used to produce the dyed polyester chip.DMSIP(CAS:3965-55-7)is also used in water dispersible resin systems applied in coating and adhesives.DMSIP(CAS:3965-55-7) is acting as the third monomer of cation modified polyester(CDPET).DMSIP(CAS:3965-55-7) has a good affinity function with cation dyestuff because of the CDPET fiber containing sulfo group,the dyed fiber is bright and lustrous,having a complete range of color and dying deeply.The modified fiber has woolens feeling,it is easily blended with fleece that is necessary for garments manufacturing.
