| Abstract: | Using melt-spun 75 dtex/144 f PET POY as raw material, 55 dtex/144 f polyester DTY was prepared on a FK6-1000 texturing machine. The production process was discussed. The results showed that the production was stable with less fuzz and breaks under the conditions as followed: processing speed 600-700 m/min, draw ratio 1.65, polyurethane friction disk 1-4-1, D/Y ratio 1.60, network pressure 0.12 MPa, setting over-feed ratio 4.00%-5.50%. The obtained 55 dtex/144 f polyester DTY with the first-grade rate of 95... |
