KB Seiren manufactures and sells synthetic fibers, as well as weaving, processing, and selling textile materials, and the production and sale of secondary textile products. The new functional polyester "Belcouple" combines regular polyester in the core and low-melting-point polyester in the sheath, allowing two types of polymers with different melting points to change into various forms through thermal processing. The woven and knitted materials made from this yarn exhibit high heat sealability (preventing misalignment), shape stability, and hardness adjustability. 【Features】 ■ Fibers melt with heat (thermal fusion) By applying thermal processing (at 190°C), the low-melting-point polyester in the sheath melts, transforming the multifilament into monofilament (single yarn), resulting in high resilience. Fabrics treated with Belcouple and heat processing can prevent fraying and misalignment. ■ Hardness is adjustable (hardness adjustability) By varying the processing temperature or combining with other materials, fabrics of different hardness can be produced. This eliminates the need for resin processing steps as in conventional methods, making it superior in cost performance and environmental hygiene. *For more details, please download the PDF or contact us.

KB Seiren manufactures and sells synthetic fibers, engages in the knitting and processing of textile materials, and produces and sells textile secondary products. The heat-reflective polyester material "Ireido" reflects infrared rays contained in sunlight and cuts ultraviolet rays, making it a heat-reflective polyester filament. "Ireido" is a conjugate filament with a core-sheath structure created through unique composite spinning and blending technologies. By incorporating infrared-reflective ceramics in the core and titanium oxide in the sheath, it provides heat-reflective effects. This material has energy-saving effects that suppress the rise in temperature inside clothing and indoor spaces, enhancing air conditioning efficiency, along with UV-cut effects, making it a comfortable and reassuring material. 【Features】 ■ Energy-saving with heat-reflective effects It prevents the entry of infrared rays by reflecting them while allowing normal light to pass through, effectively preventing temperature rises inside clothing and indoor spaces during summer, thus contributing to energy savings. ■ UV-cut for skin safety By blocking the entry of ultraviolet rays, it also provides skincare benefits through UV-cut effects, making it a friendly material for both living environments and people due to its safe and comfortable functionality. *For more details, please download the PDF or contact us.
