What are the factors that affect the breaking elongation of polypropylene high-strength yarn for safety nets?

Polypropylene high-strength yarn has very excellent properties, so that it can be used to make safety nets. What are the factors that affect the breaking elongation of polypropylene high-strength yarns for safety nets?

1. Spinning temperature

In the spinning process of polypropylene high-strength yarn, we use the same drawing multiple and different spinning temperature, and the physical properties of polypropylene high-strength yarn will be different. When the spinning temperature becomes higher, the elongation of the polypropylene high-strength yarn will become higher.

2. Side blowing temperature

Experiments have shown that the side blowing temperature has little effect on the elongation of polypropylene high-strength yarns, but too low a temperature will affect the quality of polypropylene high-strength yarns and need to be kept at a certain temperature.

3. Heat setting temperature

Lowering the heat setting temperature can increase the shrinkage rate and elongation rate of polypropylene high-strength filament fibers.

4. Drafting multiple

Within a certain range, the higher the draft ratio, the lower the elongation of the polypropylene high-strength silk fiber.

5. Strength of polypropylene high-strength yarn

The strength of polypropylene high-strength yarns has an inverse relationship with elongation. Under the same process conditions, the stronger the strength of polypropylene high-strength yarns, the lower the elongation.

Taixing Hongyang New Material Technology Co., Ltd. has a professional R&D and production team, introduces advanced technology and equipment, and is committed to producing high-quality polypropylene high-strength yarns, polypropylene air-changing yarns, polyester air-changing yarns, webbing and other products!
