| Abstract: | By applying spinneret holes with special shape and a cooling unit,a three-dimensional self-crimp polypropylene (PP) fiber was prepared from PP with the melt flow index of 25 g per 10 min by turbulence method and fast cooling technology. The production process was discussed.The results showed that the resulted fiber had favorable crimp effect,the crimp number of 10 per 25 mm and the crimp rate of 22%when the conditions were as followed:spinneret hole diameter 0.85 mm,eccentric flare angle 83°,fast cooling tank using dry ice and chilled water as cooling medium,spinning temperature 220 -235℃,winding speed 400 m/min,spin pack pressure 1.5 -4.5 MPa. |
| Keywords: | polypropylene fiber three-dimensional self-crimp fiber spinneret hole cooling unit |
