Description

Intro

GOYENCHEM-SIPM is mainly used in producing polyester, film, etc., especially in the field of Polyester fiber as the third monomer of cation modified polyester【CDP】.  It has good affinity function with cation dyestuff because of the CDP fiber containing sulfo group, the dyed fiber is bright and lustrous, having a complete range of color and dying deeply, so this kind of fiber is developing quickly at abroad.  The output of modified polyester fiber of Japan and USA amounts to more than 15%. The modified fiber has woolens feeling, it is easily blended with flex and suitable for materials for making garments.
