What are the excellent properties of differential polypropylene fiber?

Excellent mechanical properties

High strength: differential polypropylene fiber can improve strength by adjusting the internal structure of the fiber, such as increasing the degree of crystallinity and orientation. This high strength characteristic makes it widely used in industrial fields. For example, when making ropes, they are able to withstand heavier objects without breaking. Compared with ordinary fiber ropes, the strength of differential polypropylene fiber ropes may be increased several times, and can be used for ship docking cables, mountaineering ropes, etc., providing a strong guarantee for safety.

Good elasticity: Its elastic recovery ability is good. When subjected to a certain degree of stretching, it can quickly return to its original state after the stress has disappeared. In textile fabrics, this elasticity allows the garment to maintain a good shape during wearing and is not easy to deform. For example, in sports clothing, the athletes' various large-scale actions will not make the clothing slack or lose the original version, ensuring the beauty and comfort of the clothing.

Thermal performance improvement

Certain heat resistance: ordinary polypropylene fiber has a low melting point, but the differential polypropylene fiber improves the heat resistance by adding heat stabilizer or changing the crystalline structure. Performs well in some environments that need to withstand higher temperatures, such as automotive interior materials. In the interior of the car, the temperature may increase due to factors such as sunlight exposure, and the interior materials made of differential polypropylene fiber can withstand such temperature changes, and will not soften or deform because of high temperature, extending the service life of the interior materials.

Diverse optical properties

Adjustable gloss: The gloss can be adjusted by changing the cross section shape and surface treatment of the fiber. For example, the use of special-shaped cross sections (such as three-leafed, cross-shaped, etc.) of differential polypropylene fibers will produce a special luster effect, making the fabric look more beautiful. After adding matting agent, the fiber luster will become softer and used to make some high-end clothing fabrics, which can show a low-key luxury texture to meet the requirements of different consumers for the appearance of clothing luster.

Enhanced hygroscopicity (chemically modified)

Conventional polypropylene fibers are almost non-hygroscopic, while chemically modified differential polypropylene fibers can effectively absorb and disperse water by introducing hydrophilic groups (such as hydroxyl, carboxyl, etc.) into the molecular chain. In the field of sportswear and outdoor clothing, this performance advantage is obvious. When people exercise or in the outdoor environment, the body will sweat, this moisture absorption good fiber can quickly absorb sweat, and distribute it, keep the skin dry, improve the comfort of wearing.

Improved dyeing properties (after chemical modification)

Ordinary polypropylene fiber is difficult to stain because of the lack of active groups that can bind with dyes. By introducing acid dye dyeable groups and cationic dye dyeable groups, the chemically modified differential polypropylene fiber broadens the dyeing range and can dye colorful colors. This makes polypropylene fiber more widely used in clothing, home textiles and other fields, can be dyed according to different seasons, occasions and consumer preferences, greatly enriching the color choice of products.

Improved antistatic performance (after chemical modification)

The use of chemical modification, such as the addition of antistatic agents or the introduction of antistatic groups in the molecular chain, can effectively reduce the electrostatic generation of fibers. In electrostatic sensitive industries such as electronics industry and chemical industry, wearing work clothes made of antistatic differential polypropylene fiber can avoid safety accidents caused by electrostatic sparks, such as damage to electronic components, chemical raw materials explosion, etc., but also reduce problems such as electrostatic adsorption dust and keep the working environment clean.

Good softness and comfort

Fine denier differential polypropylene fiber has good softness. Its monofilament size is small, feel delicate, in the production of underwear, home textiles and other products, can provide a comfortable touch. For example, the use of fine denier polypropylene fiber in underwear fabrics, like contact with soft silk, can make consumers feel comfortable and close, improve the quality of the product and user experience.

Uv resistance (some fibers)

Some differential polypropylene fibers have anti-ultraviolet function after special treatment. When used in outdoor clothing, curtains and other products, it can effectively block the damage of ultraviolet light to the human body and indoor furniture. For example, outdoor sun-protective clothing made from this fiber can provide the wearer with sun protection, reduce the damage of ultraviolet rays on the skin, and reduce the risk of skin cancer and other diseases.
