Cationic Dyeable PET Chip is a specialized polyester chip designed for superior dye absorption and color fastness in textile manufacturing. 

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.
