Due to being made of 100% polyurethane elastic fibers, it is extremely flexible, and the unique high stretch of polyurethane elastic fibers is achieved in all directions, 360 degrees!
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.
