When purchasing polypropylene high strength yarns, many customers will pay attention to how to determine the "strength" and whether it is stable. As one of the main products of Taixing Hongyang New Materials Technology Co., Ltd., polypropylene high-strength yarns are often asked three questions in practical applications. We attempt to answer them in a straightforward manner. 

One, where does "high strength" lie? It's not about the greater the stretch, the better.

The core of high-strength fibers lies in the balance between "breaking strength" and "modulus". In simple terms: it needs to have sufficient load-bearing capacity while also not deforming excessively under force. Some fibers are very "rigid" when stretched, but break under impact; some are too soft and tend to loosen over time when used as a fabric strip under long-term stress. What we control is the stable strength range suitable for industrial use such as fabric strips and lifting belts, ensuring that the finished product can maintain its shape and toughness even under repeated stress and in humid environments. 

2. Will the strength change when the color and thickness vary?

Yes. For the same specification of  polypropylene high strength yarn, if the color shade and single filament denier (thickness) are adjusted, the process parameters need to be adjusted simultaneously. For example, the color masterbatch used for dark-colored filaments is different, and there may be slight differences in the cooling crystallization process, which may cause fluctuations in the actual strength. Experienced manufacturers will conduct on-site inspections during each batch production instead of simply copying the indicators from the previous batch. We suggest that you clearly specify the final application (such as the load-bearing grade of the webbing) when purchasing, so as to facilitate matching the most suitable filament diameter and color formula. 

III. What are the differences between air changed yarns and high-strength yarns?

Hollow-changed fibers undergo air deformation treatment, resulting in a fluffy surface and a texture similar to that of short fibers. They are suitable for making cotton-like fabrics or decorative bands. On the other hand, high-strength fibers have a higher degree of orientation and crystallinity, highlighting "strength" and "low elongation". The production lines for these two types of fibers are completely different and cannot be substituted for each other. If you need smooth edges and priority in strength for the fabric, choose high-strength fibers; if you need good coverage and soft texture, then consider using hollow-changed fibers.
