摘要:
Un renfort textile de renforcement d'une matrice de polymère de matériau composite comporte une nappe non tissée (3) constituée de fibres de lin (4) dont la pluparts s'étendent individuellement, parallèlement à une même direction (X-X') perpendiculaire à une largeur (ℓ) de cette nappe (3), lorsque ladite nappe (3) est à plat.
摘要:
A reinforcing textile complex for composite materials, comprising a stack of textile layers with a view to their impregnation by a polymer resin, the including complex comprising: • an assembly of weft threads (2); • an assembly of warp threads (3, 4) associated in pairs, each pair comprising two threads of different type, at least one of which (3) is based on high toughness threads, the two threads of a given pair being woven with the weft threads in a "leno" weave.
摘要:
A process for preparing a semi-finished textile product intended for thermoplastic injection moulding, according to which a multilayer complex comprising at least one reinforcing layer combined with a draining layer, is impregnated with at least one thermoplastic compound by passing into an aqueous solution containing said at least one thermoplastic compound. And also the product obtained by this process.
摘要:
The material for decorating a substrate of the invention includes a sheet (2) transferable by hot-pressing. A raised pattern (5, 6) is defined by a front surface (4) of said transferable sheet (2), a shape-holding layer (7) of which is obtained from a high polyurethane dry extract solution having a partial, prematurely blocked polymerization. The invention is usable in the field of fabric decoration.
摘要:
The invention relates to a method allowing the heat transfer of a multilayer complex (1) onto the front face of a textile material (13), said multilayer complex comprising a layer (5) containing polyurethane and a superimposed expansible layer (6) containing a gelled vinyl polychloride plastisol and a non-expanded heat-expansion agent. To this end: the multilayer complex is placed on the visible front face of the textile material, the polyurethane-containing layer being the furthest away from the textile material so as to form, after the transfer, a visible decorative layer on the front face of the textile material; and temperature and pressure conditions are applied so as to cause the adhesion of the multilayer complex to the visible front face of the textile material and the simultaneous expansion of the expansible layer. A three-dimensional edge effect can be obtained using different colour layers.
摘要:
The invention relates to a method for making a textile complex (10) including a textile web (11) and an upper coating layer (12) having an irregular surface condition, and comprising decorative patterns (8, 9, 58) applied onto the upper coating layer (12), characterized in that the method comprises the following steps: preparing a decorative multilayer complex (1) comprising at least three basic layers, i.e. a substrate layer (5), a colored layer (4), a heat-fusible layer (2), by cutting the colored layer (4) and the heat-fusible layer (2) along the outlines (6) of the decorative patterns (8, 9) without cutting the substrate layer (5) and then removing the fractions of said colored (4) and heat-fusible (2) layers outside the pattern areas (8, 9); arranging said prepared multilayer complex (1) on the upper coating area (12) of the textile complex (10) by means of the surface thereof with the heat-fusible layer (2); applying temperature and pressure conditions that trigger the adhesion of the heat-fusible layer (2) to the upper coating layer (12) of the textile complex; subjecting the assembly to a processing (27) resulting in a structured and regular surface condition of the upper coating layer.
