What are the factors that affect the strength of polypropylene high-strength yarn?
The strength of polypropylene high-strength yarn affects the application of polypropylene high-strength yarn. The greater the strength, the wider the application range of polypropylene high-strength yarn. This article mainly discusses the main factors that affect the strength of polypropylene high-strength yarns, such as the melt index of the raw material, the stretching speed and the stretching speed.
Through experiments, it is found that under exactly the same process conditions, the melt index of the raw materials is different, and the strength of the finished polypropylene high-strength yarn is different, and shows a certain regularity. Under the same spinning temperature, the same draw ratio and the same process parameters, the lower the melt index of the polypropylene chip, the higher the strength of the polypropylene high-strength yarn.
As the draw ratio increases, the strength of the fiber increases, and the draw ratio makes a greater contribution to the strength of the fiber.
Different drawing speed means different spinning speed, the strength of its polypropylene high-strength yarn is different, and it decreases with the increase of drawing speed.
In summary, the draw ratio has a greater contribution to the strength of polypropylene high-strength yarns.
