Latest Patents

Miyoshi's latest patents focus on ultrafine sheath-core composite fibers and the composite sheets made from them. These improved fibers possess a fineness ranging from 0.0001 to 0.5 denier. The composite fibers consist of 10 to 70% core material, which has a very high intrinsic viscosity, and 90 to 30% sheath material made from a polyester copolymer. The sheath incorporates 1.5 to 8 mole % of 5-sodium (or lithium or potassium) sulfoisophthalate, resulting in fibers that are not only strong but also dyeable with cationic dyes. When combined with elastic materials like polyurethane, these fibers can create suede-like artificial leathers that exhibit excellent softness, touch, feel, and color.
