Title:
NONWOVEN FABRIC LAMINATED STRUCTURE, ITS PRODUCTION AND PRODUCT USING THE SAME
Document Type and Number:
Japanese Patent JP3454375
Kind Code:
B2
Abstract:
PURPOSE: To obtain a nonwoven fabric laminated elastic structure capable of blocking vibration, excellent in heat durability, shape-retaining property and cushioning property, hardly causing stuffiness and constituted of a network material obtained by laminating and joining a short fiber hard stock whose heat bonding component consists of a thermoplastic elastic resin and most suitable as a cushioning material and to provide a method for producing the nonwoven fabric laminated elastic structure and to obtain a product such as quilt or cushion for furniture, beds and vehicles using the nonwoven fabric laminated elastic structure.
CONSTITUTION: In this laminated elastic structure, a nonwoven fabric, obtained by mixing a heat-bondable short fiber consisting of a thermoplastic elastic resin with a short fiber consisting of a thermoplastic nonelastic resin, opening the mixed short fiber and forming the opened short fiber in three-dimensional structure, in which most of the contact part of the yarns is fused by heat bonding and the face is flatted is joined and integrated on the one side of a network material obtained by meandering continuous yarn consisting of a thermoplastic elastic resin having ≤100000 denier fineness and mutually contacting the yarn to form a three-dimensional structure and substantially flatting both faces of the structure. The laminated elastic structure has 0.01-0.2g/cm2 density. Furthermore, this method for producing the laminated elastic structure and this product, using the laminated elastic structure are provided.
