Latest Patents
Andoh's latest patents include groundbreaking advancements in leather-like sheets. One of his patents describes a leather-like sheet that contains a microfine long-fiber nonwoven fabric. This fabric features an entangled web structure made of bundles of microfine long fibers, along with an elastic polymer that is impregnated into the fabric. The resulting leather-like sheet exhibits a machine direction/transverse direction ratio of breaking strength ranging from 1/1 to 1.3/1, with an elongation at break of 80% or more in both directions. This innovative material offers a natural dense feeling, a soft hand, and a moderate resistance to elongation, making it a durable option for various applications.
Another patent focuses on a leather-like sheet that comprises a napped part of ultrafine fibers and a grainy part of nonporous elastic polymer. This unique combination is achieved by infiltrating a porous polymer elastomer into a three-dimensionally intermingled nonwoven fabric of ultrafine fibers. The production method results in a nubuck-type leather-like sheet that boasts good surface abrasion resistance and an elegant, three-dimensional appearance akin to natural leather.
