Title:
SKIN MATERIAL SHEET, METHOD FOR PRODUCING SAME AND SOUND-ABSORBING MATERIAL
Document Type and Number:
WIPO Patent Application WO/2017/006993
Kind Code:
A1
Abstract:
To provide a lightweight skin material sheet which is able to have improved formability, while having favorable sound absorption performance; a method for producing this skin material sheet; and a sound-absorbing material. This skin material sheet is composed of: a base layer that is formed of a nonwoven fabric; and a coating layer that is formed on one surface of the base layer and contains cellulose nanofibers. This skin material sheet has a ventilation resistance of 0.2-5.0 kPa·s/m, and is produced by applying an aqueous dispersion of cellulose nanofibers to one surface of a nonwoven fabric by diffusion coating, and drying the aqueous dispersion thereon. In addition, this sound-absorbing material is obtained by laminating this skin material sheet on the surface of a layer that is formed of an air-permeable porous base.
