Cationic Dyeable PET Chip

CDP Characteristics:
These are high-pressure cationic dyeable polyester chips, with dyeing conditions
set at 120°C to 130°C and 0.13 MPa.

Advantages of CDP:

CDP fibers exhibit excellent color fastness and vibrant hues.
They facilitate cross-dyeing, resist printing, and variation dyeing effects.


ECDP Characteristics:
ECDP chips vary in Tio2 content, offering both bright and semi-dull options. They
can be dyed at standard cationic dyeable polyester chip conditions of 95°C to
100°C, under room temperature and pressure.

Advantages of ECDP:

With a higher sulfonic acid group content ranging from 2.5% to 7%, ECDP chips boast
superior dyeability, allowing for deeper colors.
They also excel in moisture absorption and possess certain anti-pilling properties.


Applications:
These chips are primarily used in the development of cellulose-like fibers.

Through specialized post-spinning false twist processing, they can produce viscose
and cotton-like fibers.

They can serve as a partial substitute for nylon 6 fibers.
