Bemberg™ is an eco-friendly fiber made from cotton linter—the short, downy fiber that enfolds and protects the cotton seed—featuring a smooth feel, attractive luster, and moisture absorption/release. Made by Asahi Kasei Fibers since 1931, Bemberg™ is used in applications ranging from linings to outerwear, innerwear, sportswear, beddings, and ethnic garments.


Featuring supple stretch and recovery, Roica™ premium stretch fiber (spandex/elastane) provides advanced functionality. It is used for women’s stockings, innerwear, swimwear and other sportswear, diapers, and medical supporters. The global Roica™ supply network includes manufacturing plants in Japan, Taiwan, China, Thailand, and Germany.


Our wide range of highly functional nonwoven products are made with advanced and innovative production technology. Eltas™ spunbond, a nonwoven fabric formed by thermal compression without the use of any binders, is the world’s only spunbond available in three different materials—nylon, polyester, and polypropylene. The ecological Bemliese™ is a binder-free, 100% cellulose cupro nonwoven made from cotton linter. Lamous™ microfiber suede is used for upholstery and automotive interiors. Pulshut™ noise suppression sheet can be applied to digital devices and cables.
