MULTILAYER LAMINATED NETWORK MATERIAL, ITS PRODUCTION AND PRODUCT USING THE SAME

Document Type and Number:

Japanese Patent JP3444374

Kind Code:

B2

Abstract:

PURPOSE: To obtain a multilayer laminated network structure, excellent in heat-resistant durability, shape retaining and cushioning properties, hardly becoming musty, constituted of a network material formed by laminating and joining staple fiber hard cotton comprising a thermoplastic elastic resin to a network material prepared by laminating many layers of the thermoplastic elastic resin and a thermoplastic nonelastic resin and optimal for a cushioning material.
CONSTITUTION: This multilayer laminated network structure is obtained by fusing and integrating continuous filaments having 100-100000 denier size, laminating and fusing a thermoplastic elastic resin layer and a thermoplastic nonelastic resin layer forming a three-dimensional solid structure, forming a laminated network material having substantially flattened surfaces, forming staple fibers comprising two kinds of the thermoplastic elastic resins into a three-dimensional structure, fusing and integrating contact parts thereof with a heat bonding component, substantially flattening the surfaces thereof and joining and integrating the resultant nonwoven fabric having the substantially flattened surfaces to the surface of the thermoplastic elastic resin layer in the laminated network material. Furthermore, this method for producing the multilayered laminated network structure is provided and a product using the same is obtained.
