Title:
THERMAL BOND NON-WOVEN FABRIC CONTAINING CYCLIC OLEFIN RESIN
Document Type and Number:
WIPO Patent Application WO/2016/194553
Kind Code:
A1
Abstract:
Provided is a non-woven fabric that absorbs only a small amount of volatile low molecular weight compound, and that has good texture when used as a non-woven fabric that makes contact with human skin. This thermal bond non-woven fabric containing cyclic olefin resin includes at least: fibers (A) containing at least 50 mass% of a cyclic olefin resin (A1) having a glass transition temperature TgA1°C; and fibers (B) containing at least 10 mass% of either a cyclic olefin resin (B1) having a glass transition temperature TgB1°C, or a crystalline thermoplastic resin (B2) having a melting point MpB2°C; the fibers (A) and the fibers (B) being heat-spliced together; wherein TgA1 > TgB1 or TgA1 > MpB2, and either the difference between the glass transition temperature TgA1°C and the glass transition temperature TgB1°C or the difference between the glass transition temperature TgA1°C and the melting point MpB2°C exceeds 20°C.
