KB Seiren manufactures and sells synthetic fibers, as well as weaving, processing, and selling textile materials, and the production and sale of textile secondary products. "Rib Fresh (R) P Super" minimizes changes in yarn quality due to the incorporation of antibacterial agents, maintaining a quality comparable to regular polyester yarn in terms of strength, elongation, and shrinkage. High-performance antibacterial glass continuously releases trace amounts of silver ions, which exhibit excellent antibacterial effects against bacteria due to their inherent properties, suppressing the growth of bacteria on the fibers. It can be used in a wide range of fields, from sportswear and workwear, where cleanliness is essential, to everyday goods. 【Features】 ■ Antibacterial and deodorizing properties Exhibits excellent antibacterial effects against bacteria, suppressing their growth on the fibers. ■ Safety Tests conducted by the Japan Food Analysis Center and the Japan Industrial Skin Hygiene Association found no toxicity, confirming high safety, making it safe for use in care applications such as nursing. ■ Durability By incorporating antibacterial agents, it offers superior wash resistance compared to post-processing products. *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 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. Textile materials made from this yarn exhibit high heat sealability (prevention of misalignment), shape stability, and hardness adjustability. 【Features】 ■ Fibers melt with heat (thermal fusion) By applying thermal processing (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 can be freely adjusted (hardness adjustability) By varying the processing temperature or combining with other materials, fabrics with 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. It is a comfortable and reliable material that helps reduce the rise in temperature inside clothing and indoor spaces, enhancing cooling effects and offering energy-saving benefits along with UV-cut effects. 【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 increases 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 skin care benefits through UV-cut effects, making it a material that is safe and comfortable, contributing to a gentle lifestyle for people. *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. "Bell Split" is an ultra-high shrinkage fabric that uses the microfiber "Beryma (R) X," which is a blend of polyester and nylon, and has undergone a unique high shrinkage processing. Due to its special high-density processing, it blocks rain and wind while allowing sweat and moisture to escape, creating a comfortable internal space in clothing that is less prone to dampness. 【Features】 ■ Elegant and finely textured feel By using microfiber with the properties of both polyester and nylon in both the vertical and horizontal directions, and applying ultra-high shrinkage processing, it expresses a unique firmness and fine texture. ■ Pursuit of high functionality that prevents rain and dampness By adding ultra-high shrinkage processing technology to the fine fiber technology and composite spinning technology that created "Beryma X," it achieves excellent moisture-permeable waterproofing and breathability. *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. "Espansion" is a spunbond nonwoven fabric made from thermoplastic polyurethane elastomer developed by KB Seiren using its unique technology. Due to its structure of thin continuous filaments made of 100% polyurethane elastic fibers randomly layered, it possesses many excellent features, including high elasticity (approximately 400%) and flexibility, in addition to the traditional spunbond characteristics of breathability and handling. "Espansion" leverages these properties and is expected to have potential for various applications as a new material. 【Features】 Flexibility: Extremely flexible due to being made of 100% polyurethane elastic fibers. Breathability and water permeability: Excellent breathability and water permeability due to the structure where thin filaments are layered and only the intersection points are bonded. Dust collection: Prevents the passage of fine dust particles due to the dense layering of fibers. Welding and cutting: Easy processing for welding and cutting using high-frequency welders, heaters, etc. *For more details, please download the PDF or contact us.

KB Seiren is engaged in the manufacturing and sales of synthetic fibers, the knitting and processing of fiber materials, and the manufacturing and sales of secondary fiber products. In response to the needs of the times, we have developed the wiping cloth "Zavina MX," which can fully accommodate the ultra-clean environment of super clean rooms. Wipers used in clean rooms play a role in cleaning without contaminating instruments, devices, and surrounding items, while also achieving water absorption. "Zavina MX," which possesses all the necessary characteristics required for wipers, is indeed a high-performance wiping cloth born from the high-tech era. With our unique technology, we achieve ultra-high shrinkage both vertically and horizontally, resulting in high density. The surface of the wiping cloth captures dust with 82,550 fibers per square centimeter. 【Features】 ■ Extremely low self-generated dust ■ Excellent water absorption (absorption speed and retention capacity) ■ Minimal elution components such as residual ions ■ Good cleaning ability (removes dirt without causing re-contamination) *For more details, please download the PDF or contact us.
