By introducing the third monomer of sodium sulfonate group (-SO3Na) in the polymerization of recycled PET,
the recycled semi-extinction, bright, normal temperature and atmospheric pressure cationic chip can be obtained to ensure that the respun polyester yarn can chemically react with cationic dyes.
The spun recycled polyester yarn can chemically react with cationic dyes, so that the dye is easy to fix on the recycled polyester yarn,
and the use of its textile has the advantages of easy color absorption, high color rate, bright color and can be mixed with ordinary polyester,
and finally dyed into hemp gray two-color, multi-color silk.
