In the chemical fiber industry, polypropylene high strength yarn has long been labeled as "strong industrial yarn". When people think of it, they often associate it with heavy-duty lifting belts, outdoor sunshade nets, or car seat belts. However, with the rising demands of the consumer market for functional textiles, an interesting question has been repeatedly raised: Can this fiber, known for its "strength", also exhibit a "soft" aspect?

The molecular structure of polypropylene high-strength yarn determines its excellent resistance to breakage and chemical corrosion. However, "high strength" and "skin-friendly" are not mutually exclusive. Taixing Hongyang New Materials Technology Co., Ltd. discovered through process adjustments that when the twist coefficient of the high-strength yarn matches the fabric's organization density reasonably, the texture can change significantly.

The feeling of skin-friendly contact is closely related to the pressure distribution and heat and moisture transfer efficiency when the fiber comes into contact with the skin. Polypropylene materials have a low thermal conductivity, so there is no cold sensation upon contact; at the same time, its non-absorbent property makes sweat stains difficult to adhere and bacteria less likely to breed, which are inherent conditions that are friendly to the skin. Hongyang New Materials introduced an air flow network treatment on the polypropylene high-strength yarn production line, forming regular bonding nodes on the surface of the long fibers, which not only maintains the bundled strength of the yarn but also increases the overall fluffiness. After this treatment, the high-strength yarn woven into fabrics has a reduced stiffness, while the wrinkle recovery and softness are improved.

The basic raw material of polypropylene high strength yarn is polypropylene, which itself belongs to a flexible chain polymer and has inherent flexibility. The reason for its high-strength characteristic lies in the high-bias stretching orientation process during spinning. If the orientation degree is guaranteed, the single filament density is reduced, and a composite spinning component is adopted, it is possible to change the hand feel of the yarn on a macroscopic level. The R&D team of Taixing Hongyang New Materials Technology Co., Ltd. has mastered the core parameters for preparing fine-diameter polypropylene high-strength yarn through multiple rounds of sample trials, ensuring that the breakage strength retention rate of the finished product is not lower than that of conventional products while effectively controlling the bending stiffness.

In addition, the friction coefficient is an important indicator affecting the skin-friendly perception. An excessively high friction will cause dragging and irritation, while an excessively low friction is prone to slippage, resulting in unstable adhesion. Hongyang New Materials adjusted the formula proportion of the spinning oil agent to form a uniform thin layer lubricating film on the fiber surface, controlling the dynamic friction coefficient of the polypropylene high-strength yarn within an appropriate range. This improvement not only enhances the contact comfort but also reduces the breakage rate during weaving, bringing more ideal processing efficiency to customers.

It is worth noting that polypropylene hollow yarn and polyester hollow yarn have gained market recognition for their soft characteristics due to their curled and fluffy surface. Nowadays, polypropylene high-strength yarn is drawing on certain decyling and blowing spinning principles from the hollow yarn process to develop intermediate product types that combine strength and feel. This provides new material options for outdoor equipment, military and police training uniforms, and other fields that require both durability and comfort.
