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