Title:
FIBER STRUCTURE AND METHOD FOR PRODUCING SAME
Document Type and Number:
WIPO Patent Application WO/2018/159729
Kind Code:
A1
Abstract:
The objective of the present invention is to provide: a fiber structure which is used for bedding mattresses, bed covers and other bedding, seats for various vehicles, furniture cushions, and the like, and which provides exceptional comfort; and a method for producing the fiber structure. The objective can be solved with a fiber structure wherein crimped short fibers and heat-bonding composite short fibers obtained by providing, on the surface as a heat-bonding component, a thermoplastic resin having a melting point that is at least 40°C lower than that of a thermoplastic resin forming the crimped short fibers, are blended at a specific weight ratio. In the fiber structure, fixation points where the heat-bonding composite short fibers intersect each other and are thermally fused, and/or fixation points where the heat-bonding composite short fibers and the crimped short fibers intersect and are thermally fused, are dispersed. The fiber structure has a laminate structure of at least three layers with defined thickness and density, wherein when the fiber structure is divided into three parts, the ratio of hardness between the middle layer part and the surface layer part is 0.60 or more.
