The present research studied the production process and performance of biobased PA56 (polyamide 56) and PET (polyethylene terephthalate) composite fibers through melt side-by-side spinning. The results showed that biobased PA56 and PET composites with strength of 4.0–4.3 CN/dtex were prepared by applying a spinning speed of 4,000–4,050 m/min, draw ratio of 2.50–2.70, first heat roll temperature of 80–90 °C, second heat roll temperature of 160–165 °C, and the addition of 5% compatibilizer between the two components. The fibers and fabric showed high moisture absorption, good air permeability, and excellent antistatic properties. The saturated moisture absorption rate was 11.2%, the air permeability was 9680 g/(m2·d), and the specific resistance was 1080*1010 Ω·m. |
