Relationship polypropylene stretch yarn false twisting process and spinning temperature
Olefinic thermoplastic polypropylene fiber, it has good deformability and heat-setting performance. Therefore, production of polypropylene stretch yarn using false-twist texturing method.
False twist heating temperature is high, good distortion performance yarn. But the temperature is too high, it can cause strength and elongation drop wire to form a stiff wire, yarn and even melt adhesion phenomenon. When the temperature is heated to 150 , yarn melt adhesion occurs when the temperature drops to 145 , melt adhesion disappears, but the breakage rate is still very high, when the temperature is lowered to 140 , the 0 breakage rate reduced, false twist runs smoothly.
