Recycled polyester fiber with the chemical method of dyeing at low temperature and normal pressure

Recommendation Reasons

The advanced chemical recycling production technology was upgraded and modified by combining polymerization, and the variety innovation of recycled polyester fiber was realized. Low-temperature, normal-pressure dyeing and high-quality comfort are integrated into the fiber, and the environmental protection effect is superimposed to upgrade the low carbon effect.

Processing Technology

Advanced chemical recycling technology and process equipment were adopted, and modified

chips were prepared by polymerization modification with fourth monomer cationic auxiliaries,

and then the recycled polyester fiber with dyeing at low temperature and normal pressure was

spun-prepared.

Q: Do you know the advantages of differentiated product design, energy

saving and emission reduction technology of recycled polyester fiber with the

chemical method?

A: Chemical recycling system can integrate environmental protection,

functionality and other characteristics into recycled polyester fiber. In the

process of macromolecules being depolymerized into monomers and

repolymerization, different functional additives can be added for modification

to realize different functions of fibers. Compared with the traditional

production process with petroleum refining as the raw material, CO2emission

is reduced by 52% and energy consumption is reduced by 39%.
