Title
(EN) COEXTRUDED THERMOPLASTIC STRUCTURAL MATERIAL FOR SHOES AND MANUFACTURING PROCEDURE OF COEXTRUDED MATERIAL
(FR) MATERIAU STRUCTURAL THERMOPLASTIQUE COEXTRUDE POUR CHAUSSURES ET PROCEDE DE FABRICATION DUDIT MATERIAU COEXTRUDE
Abstract
(EN)
This invention refers to an innovating structural material for footwear, thermoplastic and coextruded with thermoadhesives, comprising a multilayer material. The invention also refers to a manufacturing procedure of said structural material for shoes. The structural material proposed may consist of: only a sheet of thermoplastic resins; one sheet of thermoplastic resins coupled to a substratum of woven or non-woven material on only one side; a sheet of thermoplastic resins coupled to two similar or different of woven or non-woven substrates on the two sides (right and reverse). The substrate may use, among others, the following materials: nonwoven polyester, nonwoven polypropylene, polyester web, cotton web, PVC sheet, cotton flake, jersey, mesh, etc. Its thickness may vary according to the material to be laminated. The thermoplastic sheet consists of the following layers: external layers A and C formed by thermo-reactivatable adhesives such as EVA (ethyl-vinyl-acetate), taquifying esters and auxiliary additive substances of flow, such as amides. These layers may present a different formulation among them, according to the use to be given to the structural material. Intermediate layer B formed by polyolefinic resins such as polypropylene, polyethylene or ethylene copolymers of ethylene.

L'invention concerne un nouveau matériau structural pour article chaussant, thermoplastique et coextrudé, pourvu de thermoadhésifs, comprenant un matériau multicouche. L'invention concerne également le procédé de fabrication dudit matériau structural pour chaussures. Ce matériau structural comprend une feuille de résines thermoplastiques couplée à un substrat de matériau tissé ou non tissé recouvrant une surface de ladite feuille, une feuille de résines thermoplastiques couplée à deux substrats identiques ou différents tissés ou non tissés recouvrant les deux surfaces de ladite feuille (endroit et envers). Le substrat peut utiliser, entre autres, un polyester non tissé, un polypropylène non tissé, une bande de polyester, une bande de coton, une feuille en PVC, des flocons de coton, du jersey, un réseau maillé, etc. Son épaisseur peut varier en fonction du matériau à stratifier. La feuille thermoplastique comprend des couches extérieures A et C formées par des adhésifs thermoréactifs tels que l'éthyl-vinyl-acétate (EVA), des esters collants et des substances d'additifs auxiliaires d'écoulement, telles que des amides. Les couches peuvent posséder une formulation différente en fonction de l'utilisation du matériau structural. La couche intermédiaire B est formée de résines polyoléfiniques telles que du polypropylène, du polyéthylène ou des copolymères d'éthylène.
