| Abstract: | The production process of self-crimping PTT/PET composite fiber was discussed.The results showed that by using PTT chips with the intrinsic viscosity of 1.25 dL/g(spinning temperaturen was 275~280℃),PET chips with the intrinsic viscosity of 0.50 dL/g(spinning temperature was 260~265℃)and the special side-by-side spinning pack could produce the self-crimping PTT/PET composite fiber with stable quality and good performance under the conditions of draw ratio 2.85,winding angle 6.5°,winding tension0.16 cN/dtex,winding speed 4100 m/min,and realized the mass production. |
