How much do you know about the spinning temperature of polypropylene high-strength yarn?

The spinning temperature of polypropylene high-strength yarn is mainly determined according to the melt index of the polypropylene raw material, because it is necessary to ensure the necessary flow properties of the melt into fiber, and also to minimize the thermal degradation in the process of arrogance to ensure that the nascent fiber has a higher Molecular weight, which makes polypropylene high-strength yarn possess high-strength performance.

Because at a higher spinning temperature, the nascent fiber has greater fluidity and low pre-orientation before crystallization, and maintains an unstable quasicrystalline structure, so that a higher post-drawing ratio can be used later to obtain For high-strength fibers, it is generally necessary to select a higher spinning temperature. The temperature of each zone of the screw should be 270~280℃, and the temperature of the spinning box should be controlled at about 285℃.

The above is some knowledge about the spinning temperature of polypropylene high-strength yarn. The editor of Taixing Hongyang polypropylene high-strength yarn manufacturer hopes that the above introduction can be helpful to everyone.

Taixing Hongyang New Material Technology Co., Ltd. has a professional R&D and production team, introducing advanced technology and equipment, and is committed to producing high-quality polypropylene high-strength yarns, polypropylene air-changing yarns, polyester air-changing yarns, ribbons and other products! The company is still growing, and we look forward to working with you for a win-win cooperation!
