Latest Patents

Nomura's latest patents focus on the development of elastic artificial leather and the production methods associated with it. The first patent discloses a method for producing elastically stretchable artificial leather. This method includes several steps, such as forming microfiberizable fibers into a web, entangling the web to create an entangled nonwoven fabric, and converting the microfiberizable fibers into microfine fibers to produce a substrate for artificial leather. The process continues with the production of artificial leather from the substrate, followed by bringing the artificial leather into close contact with an elastomer sheet that is stretched in a machine direction. The artificial leather is then allowed to shrink in the machine direction while heat-treated, resulting in a shrunk state that is peeled off from the elastomer sheet.
