Polypropylene industrial yarn
Polypropylene industrial yarn in industrial applications, but you know it can also show their skills in the car seat belts?
In recent years, the strong development of China's auto industry has led to the rapid growth of the automobile seat belt industry. In addition, people's awareness of automobile safety is increasing day by day. The mandatory requirements of relevant policies and regulations make the market demand for car seat belts huge. It is predicted that global vehicle production in 2016 will be around 95 million vehicles, and the demand for seat belt materials will reach around 550,000 t. Due to its low strength, vinylon material is used less and less in actual production. However, the cost of polypropylene is less than one-half of that of nylon and vinylon in meeting the processing requirements of seat belts. Therefore, the development strength is high and abrasion resistance is good. The substitution of traditional industrial belt material with less polypropylene industrial yarn has become a global trend.
In this study, a polypropylene industrial yarn for high-strength seat belt was prepared by the optimized melt spinning process. The influence of spinning process on the fiber strength was discussed. The crystallization and mechanical properties of the yarn were tested. Automotive Polypropylene industrial yarn product performance, increase product added value has important value.
The value of Polypropylene industrial yarn is immeasurable, the field of application is also gradually expanding, the market prospects worth the wait.
