Latest Patents

Yasui holds a patent for a non-woven fabric usable as a substratum sheet for artificial leather. This invention involves a unique process where fibrous bundles, consisting of extremely fine filaments or fibers with a denier of 0.005 to 0.5, are allowed to spontaneously adhere to each other without the use of adhesives. The resulting fibrous bundles are then formed into sheets or webs, which undergo a non-woven fabric forming operation that entangles the bundles together. This innovative method results in a non-woven fabric with relatively high flexural rigidity.
