Abstract

Produced in a single weaving operation, they comprise two or more than two yarn layers tangential to one another and superimposed. The yarns of the various layers are of different types, at least in the warp direction. The shaping occurs as the result of the sliding effect caused between the various layers, with the possibility of using heat-shrinkable yarns completely or partially.

Description

TISSUS COMPLEXES SPECIALEMENT CONCUS POUR MISE EN FORME.COMPLEX FABRICS SPECIALLY DESIGNED FOR FITNESS.

L'invention consiste à utiliser un tissu de structure tridimensionnelle, caractérise d'une part par la mise en oeuvre d'un grand nombre de fils de chaine,et par la mise en oeuvre simultanée d'un nombre important de fils de trame, généralement superposees les unes sur les autres dans un même plan vertical perpendiculaire au sens de déroulement de la chaine.Etant par ailleurs précise que la dite structure tridimensionnel le comporte deux nappes ou plus, nettement différenciées entre elles, l'ensemble étant réalisé en un seul tissage sans soudure, ni coutue,ni collage. The invention consists in using a fabric of three-dimensional structure, characterized on the one hand by the use of a large number of warp threads, and by the simultaneous use of a large number of weft threads, generally superimposed on each other in the same vertical plane perpendicular to the direction of unwinding of the chain. Being also precise that the said three-dimensional structure comprises two or more layers, clearly differentiated between them, the whole being produced in a single weaving seamless, neither costly, nor glued.

Lors de la mise en fcrme,la modification structurale de l'ensemble
e ait par décalage as nappes les unes par rapport aux autres
Ex A. Tissu complexe compertant une nappe de tissu tridimensionnel en fil monobrin Polyester. La dite nappe, présentant un vide intérieur de 75 %, et relativement épaisse constitue l'armature mécanique de
l'ensemble. Elle est associée à une couche de surface en fil monobrin,
chaine et trame, ou seulement l'une des deux.La dite couche multibrin, généralement moins épaisse, constituant l'aspect de surface, interne ou externe, recherché après mise en forme, notamment par emboutissage Avec: un tel tissu on obtient sans prebléme une cuvette circulaire à .fond plat1mesurant 50 Oms de diamétre peur une profondeur de 22 Oms. During the setting up, the structural modification of the whole
e has offset by tablecloths with respect to each other
Ex A. Complex fabric comprising a three-dimensional fabric tablecloth in single-strand polyester yarn. Said ply, having an internal vacuum of 75%, and relatively thick, constitutes the mechanical armature of
all. It is associated with a single-strand surface layer,
warp and weft, or only one of the two. The said multi-strand layer, generally less thick, constituting the surface appearance, internal or external, sought after shaping, in particular by stamping With: such a fabric is obtained without preblem a circular bowl with a flat bottom measuring 50 Oms in diameter for a depth of 22 Oms.

Il n'y a ni plis ni trace de déformation apparente de la face multibrin située dans ce cas à l'intérieur du volume.There are no folds or traces of apparent deformation of the multi-strand face located in this case inside the volume.

Dans le cas d'emboutissage à chaud,on peut utiliser en totalité ou partiellement des fils thermo-rétractibles,et en moduler lé retrait thermique.De même pour les problémes de filtres,on peut par exemple un monobrin FEP partiellement rétracté avant tissage et faire varier la porosité en fonction du retrait contrôlé.In the case of hot stamping, heat-shrinkable threads can be used in whole or in part, and the thermal shrinkage can be modulated. Similarly, for filter problems, it is possible, for example, to make a FEP solid-state strand partially shrunk before weaving and make vary the porosity according to the controlled shrinkage.

Ex B.Tissu comportant une couche monobrin Polyester prérétracté, une couche fil métallique (acier inox,cuivre,aluminium,etc) et éventuellement une couche extérieure mince,destinée à recevoir un vernis de protection.On peut ainsi obtenir toutes sortes de coupoles, plus ou moins profondes,convenant notamment à réaliser des collecteurs d-'ondes.De même des antennes de radar,autoporteuses si l'ensemble comporte des logements réalisés au cours même du tissage,sans Çouure,ni soudure,ni collage.Ex B. Fabric with a pre-shrunk polyester single-strand layer, a metallic wire layer (stainless steel, copper, aluminum, etc.) and possibly a thin outer layer, intended to receive a protective varnish. We can thus obtain all kinds of domes, more or shallower, particularly suitable for making wave collectors. Similarly, radar antennas, self-supporting if the assembly includes housings made during weaving, without seaming, welding or gluing.

Avan-ages:cout faible poids réduit,simplification corrélative des dispositifs de support et d'orientaion.On peut aussi noter que la paroi en fil monobrin Polyester est brise-vent. Advantages: low cost, reduced weight, correlative simplification of support and orientation devices. We can also note that the polyester single-strand wall is windbreak.

. Ex C.Tissage entiérement métallique,par superposition en un
seul tissage de nappes de fils métalliques de nature différente,
notamment pour filtres,tamis,etc. . Ex C. Entirely metallic weaving, by superposition in one
single weaving of plies of metallic threads of a different nature,
especially for filters, sieves, etc.

Ex D.Tissus de prctectlon:on superpose éventuellement trois couches de tissu:une couche extérieure composée d'un fi!
complexe (25 %coton + 75 % polyester muitibrin)
couche médiane en aramide ou équivalent,de préférence en
titre fin,et couche d'envers identique à la face de dessus:
Applications vestes d'escrime, gilets de protection.Dans ce dernier cas on peut superposer un certain nombre de couches
alternées Et de même en augmentant l'épaisseur pour des
problémes de blindage,etc.Ex D. Prctectlon fabrics: if necessary, three layers of fabric are superimposed: an outer layer composed of a thread!
complex (25% cotton + 75% polyester muitibrin)
middle layer in aramid or equivalent, preferably in
thin title, and reverse layer identical to the top side:
Applications fencing jackets, protective vests, in the latter case a number of layers can be superimposed
alternately And likewise by increasing the thickness for
shielding problems, etc.

En ce qui concerne les cuirasses pour combat au sabre, on
remplace la couche supérieure de surface des vastes d'
escrime par une couche dense de fils métalliques, notamment
acier inox, d'épaisseur convenable, conductrice
Ces tissus sont suceptibles d'etre mis en forme, pour tous problémes de protection, la coupe et la confection étant grandement facilitées par la cite mise en en
principe préalable.Regarding the saber combat breastplates, we
replaces the upper surface layer of the vast
fencing with a dense layer of metallic wires, in particular
stainless steel, of suitable thickness, conductive
These fabrics are likely to be shaped, for all protection problems, cutting and making being greatly facilitated by the quotation
preliminary principle.

Applications générales:il ressort de tous les exemples cicités que l'invention qui onsiste à créer des tissus spéciale- ment déformables est applicable à toutes structures renforcées.General applications: it emerges from all the examples cited that the invention which seeks to create specially deformable fabrics is applicable to all reinforced structures.

L'imprégnation pouvant avoir lieu avant ou aprés la mise enferme tout enmaintenant la possibilité d'introduction d'éléments dans des logements prévus lors du tissage.The impregnation can take place before or after the setting, while maintaining the possibility of introducing elements into housings provided during weaving.

Ex E.Elément de carrosserie,d' avion,etc,d' un tissu comportant deux couches de fil Polyester,lrune en fil multibrin,l'autre en fil monobrin.L'impoe'gnation peut être totale ou partielle:
Pour gagner du poids on peut n'imprégner, peindre, enduire etc que la seule face multibrin. Ex E. Element of bodywork, airplane, etc., of a fabric comprising two layers of polyester yarn, one in multi-strand yarn, the other in single-strand yarn. The taxation may be total or partial:
To gain weight, you can only impregnate, paint, coat, etc. the single strand side.
