Cationic Dyeable Polyester Chip
Cationic Dyeable Polyester Chip for CDP Yarn Spinning
Bright Original or Recycled CDP or ECDP for CD Polyester Fiber
Description: Generally speaking, Cationic Dyeable Polyester Chip can be
divided into two types, CDP and ECDP.
CDP refers to the high-pressure cationic dyeable polyester chip and the
dyeing condition is at 120-130℃ under 0.13MPa.
ECDP is the normal pressure chip and the dyeing condition is at 98-100℃.
Characteristic： For CDP, the advantage is that CDP fiber has a higher
colorfastness, brighter color, and easy to obtain the effect of cross-dye,
white space, and variant dye. The disadvantage is that the dyeing process
needs to be done at high temperatures and under high pressure. And what’s
worse, CDP fiber can not be blended with other synthetic fibers.
ECDP is developed to solve the defect of CDP and also maintain the strength
of CDP. So we can say, ECDP is the modified one based on CDP.
Classification: According to the luster (the content of TiO2), there are
Bright and Semi-Dull CDP/ECDP.
According to raw material, there are Original CDP/ECDP, Recycled CDP/ECDP,
Recycled Cloth CDP/ECDP.
