Multifunctional, heterogeneous, sectored technical fabric, directly usable for manufacturing various finished articles or products

Abstract

A method for obtaining a multifunctional, heterogeneous, sectored technical fabric usable for manufacturing various finished articles or products. A multiplicity of respectively different functional areas are defined and marked on a template of a flexible part belonging to the article to be produced; a multisector fabric including a multiplicity of respectively different textile sectors is constructed, which sectors respectively correspond to the areas defined in step (a), the latter being able to be respectively contained in the different sectors; the fabric constructed according to step (b) is woven to obtain a multisector fabric part; fabric cutting means are available, able to be referenced with respect to the drawing of the fabric; and the monoblock but multifunctional flexible part is thus directly cut and obtained. The invention can find an application in different sectors, and in particular in that of footwear for which the upper has to be obtained.

Technical fabric ( 3 ,  31 ,  32 ), obtained or able to be obtained in a single weaving operation, characterized in that the fabric, of monolithic but heterogeneous construction or structure, comprises a multiplicity of discrete textile sectors (a 1  to e1; a 2  to e 2 ) each constituting an individualised fabric part, the ordered construction of which differs from one textile sector to another, in the direction of the warp ( 6 ) and/or that of the weft ( 5 ), by at least one of the following parameters:
 the weaving and/or the density of the assembled warp threads and/or weft threads,   the nature, in particular chemical, of said threads, and/or their intrinsic construction,   the processing of said threads before and/or after their assembly,   
       so that the technical or practical properties or characteristics of the different textile sectors are respectively different, for example in the direction of the warp and/or that of the weft. 
     
     
         2 . Technical fabric according to  claim 1 , characterized in that it is constructed in such a way that one or more identical or different templates ( 61 ,  62 ) each comprising a multiplicity of different textile sectors according to  claim 1 , are repeated on the fabric in the direction of the warp ( 6 ) and/or the direction of the weft ( 5 ). 
     
     
         3 . Technical fabric according to  claim 1 , characterized in that warp threads ( 6 ) and/or weft threads ( 5 ) each comprise at least one mechanically resistant material, for example a para-amid, and/or an abrasion resistant material, for example a polyamide, and may be coated, for example with a polyurethane, which may be charged with ceramic. 
     
     
         4 . Technical fabric according to  claim 1 , characterized in that at least one textile sector comprises thermofusible warp and/or weft threads suitable for subsequent heat treatment so as to bind the threads to one another, for example to form and/or locally rigidify the fabric. 
     
     
         5 . Technical fabric according to  claim 1 , characterized in that the warp threads ( 6 ) and/or weft threads ( 5 ) individually have a simple or complex intrinsic construction. 
     
     
         6 . Use of a template ( 61 ,  62 ) in a technical fabric, or of a technical fabric ( 3 ) identical to that defined by any one of  claims 1  to  5 , as a semi-finished product to directly obtain, by flat cutting in the fabric, at least one multifunctional flexible part ( 1 ) comprising a multiplicity of functional areas (A 1  to E 1 ; A 2  to E 2 ) having respectively different functions, properties/characteristics from one area to another. 
     
     
         7 . Use according to  claim 6 , characterized in that cutting means are available and the latter are positioned and referenced with respect to the design drawing of the different textile sectors on the technical fabric so that the functional areas are individually and respectively contained in the different textile sectors of the fabric. 
     
     
         8 . Monolithic, multifunctional flexible part ( 1 ), able to be obtained or obtained by use according to  claim 6  or  7  of a template ( 61 ,  62 ) in a technical fabric, or of a technical fabric ( 3 ) identical to that defined by any one of  claims 1  to  5 . 
     
     
         9 . Manufacturing method of a finished article ( 7 ), or product, comprising a flexible part ( 1 ) according to  claim 8 , which gives technical or practical properties/characteristics differing from one discrete area to another of said part, and therefore of said article, method characterized in that:
 (a) said flexible part ( 1 ) is initially procured,   (b) said flexible part is shaped,   (c) the shaped flexible part is assembled with one or more other components ( 8 ) of said article to obtain a finished article or product ( 7 ).   
     
     
         10 . Article ( 7 ) or product able to be obtained by a method according to  claim 9 . 
     
     
         11 . Footwear article ( 7 ) according to  claim 10 , in particular a sport shoe, for example a shoe for the pursuit of a racket sport, characterized in that the flexible part ( 1 ) according to  claim 8  directly constitutes the upper of the footwear article. 
     
     
         12 . Footwear article ( 7 ), in particular a shoe for the pursuit of a sport, for example a racket sport, characterized in that the upper ( 1 ) of the footwear article is constituted by or comprises a technical fabric of monolithic but heterogeneous construction or structure, as it comprises a multiplicity of discrete textile sectors each constituting an individualised fabric part, the ordered construction of which differs from one textile sector to another in the direction of the warp and/or that of the weft, by at least one of the following parameters:
 the weaving and/or the density of the assembled warp threads and/or weft threads,   the nature, in particular chemical, of said threads, and/or their intrinsic construction,   the processing of said threads before and/or after manufacturing of the footwear article ( 7 ),   
       so that the technical or practical properties or characteristics of the upper ( 1 ) differ from one discrete area to another of the latter.
