Chun Chi introduce you to control the temperature of high-strength polypropylene yarn spinning

Polypropylene high tenacity yarn spinning process should not be underestimated, many factors should be considered which control the spinning temperature is the more important part of the period, for high-strength polypropylene spun yarn. Quality to meet the requirements of high quality and reflect the surplus. For you to do the following description:
 
The spinning temperature according to the melt index polypropylene material may be, we must ensure that the necessary fiber-forming melt flow properties, but also to minimize the thermal degradation of the spinning process to ensure that the nascent fiber has a high molecular weight, thereby high strength wire. Further, since the spinning at high temperature, crystallization occurs before the nascent fibers have greater flowability and low pre-orientation, and remain unstable quasicrystalline structure, so that the back can be a high draw ratio after thereby obtaining a high-strength fibers. It is generally choose a higher spinning temperature, temperature of each screw stalk to 270-280 ℃ is better, spinning box temperature controlled at about 295 ℃ appropriate.
