Raw material requirement: polyester chip virgin grade, chip off grade, and washed bottle flakes.
First step: the spinning line for this project starts from vacuum dryer and finishes at the fiber can turn table, and the spinning machine makes use of high pressure, melting spinning technology.
Second step: this project starts from the creel stand and finishes at the baler.
Second step (solid fiber): creel stand → cable guide → dipping bath → first drafter → draw bath → second drafter → steam chest → third drafter → crimper → conveyor → j duct → relaxing heat setter → tension device → cutter → fibre transport device → baler.
