Document Type and Number:
WIPO Patent Application WO/2020/218092
Kind Code:
A1
Abstract:
Provided is a fiber layered body wherein the cohesion between a non-microfiber layer and a microfiber layer comprising thermoplastic elastomer fibers is excellent. The fiber layered body includes a microfiber layer having a mean fiber diameter of less than 10 μm and comprising thermoplastic elastomer fibers, and a non-microfiber layer adjacent to the microfiber layer and comprising fibers with a mean fiber diameter of 10 to 30 μm. The interlayer detachment strength between the microfiber layer and the non-microfiber layer is 0.40 N/5 cm or greater. Relative to the thickness of the fiber layered body, the height difference between protrusions and recesses on the fiber layered body surface is 40% or less.
