1. Introduction

Super Chlorine Resistant Spandex is a specialized elastic fiber engineered to withstand the aggressive degradation caused by Chlorine (commonly found in swimming pools) and other disinfecting chemicals. While standard Spandex quickly becomes brittle, loses its elasticity, and breaks after a few swims, this super-resistant fiber ensures that swimwear maintains its shape and stretch several times longer.

Qianxi super chlorine-resistant spandex is a new high-grade differentiated product which has super chlorine resistance. The damage by active chlorine can be effectively avoided during daily washing, bleaching or in swimming pool.

The product has super chlorine resistance compared with the ordinary chlorine-resistant spandex. It can keep excellent performance of strength and elastic recovery under the environment with high concen-tration of active chlorine. Meanwhile, it also maintain the high-tempera-ture resistance and uniformity. Those problems like spandex broken in cloth, stripes, unsmooth surface caused by spandex fused or deteriorat-ed will be avoided during the processes like high temperature singeing. setting and dyeing.

It has excellent resistance to chlorine bleaching, which can effectively avoid the problem that spandex is easily damaged in daily care, swimming pool environment and heavy rinsing.

2. Composition

The yarn is based on a Polyurethane polymer backbone but is enhanced with advanced chemical technologies:

• Anti-chlorine Stabilizers: Deeply integrated into the polymer molecular structure to block oxidation caused by Chlorine.

• Surface Protective Film: A specialized coating that prevents pool water from rapidly penetrating the fiber core, protecting the internal polymer bonds.

3. Key Characteristics

• Exceptional Chlorine Durability: Retains high elastic strength even under continuous exposure to high concentrations of Chlorine.

• UV and Sunscreen Resistance: Resists damage from sunlight and body oils/lotions, preventing the fiber from yellowing.

• Long-lasting Shape Retention: Prevents fabrics from "bagging" or sagging after use in water.

• Color Fastness: Helps maintain fabric color integrity when exposed to bleaching agents.

5. Applications

• Professional Swimwear: Competition swimsuits, premium swimwear for men, women, and children.

• Water Sports Gear: Wetsuits, surfing gear, and water polo uniforms.

• Hot Spring Wear: Designed to withstand mineral-rich and high-temperature water environments.

6. Conclusion

Super Chlorine Resistant Spandex yarn is the ultimate solution for swimwear brands focusing on durability and high performance. It not only extends the lifespan of the garment but also provides confidence to the wearer through its ability to maintain perfect shape in harsh environments.
