Semi-dull Cationic Dyeable Polyester Chip for CDP Yarn Spinning
Bright CDP or ECDP for Cationic Fiber BCF Yarn Melt/Extrusion Spinning
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 standard pressure chip, and the dyeing condition is at 95-100℃, which can significantly decrease the production cost.
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 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 type of CDP. Especially ECDP fiber can be blended with wool and silk.
ECDP Chips can also produce BCF yarn for carpets.
The above picture compares Cationic Fabric made from different PET chips. From it, we can clearly see the fabric made from our polymer has the best dyeing effect.
