MXPA00009016A - Flat textile structure with predetermined separation line - Google Patents

Abstract

In a double woven fabric with an upper layer (1) and a lower layer (2), provision is made that, in the area of a desired predetermined separation line (9), a thread system with warp threads (3, 6) and weft threads (4, 5 or 4', 5') alternates out of the upper layer (1) into the lower layer (2) and a thread system alternates out of the lower (2) into the upper layer (1). At both sides of the desired predetermined separation line (9), the threads (3, 6, 4, 5 or 4', 5') alternating between the upper layer (1) and the lower layer (2) and vice versa are separated in the lower layer (2). Created thereby is a flat textile structure with a predetermined separation line (9) invisible from the viewing side of the surface of the double woven fabric.

Description

SMOOTH TEXTILE STRUCTURE WITH DEFAULT SEPARATION LINE Prior Art The smooth textile structures are already known, which, when necessary, open or divide into a defined area when a predetermined minimum force is applied in the direction transverse to the woven plane. Smooth textile structures with a predetermined separation line are used, for example, in motor vehicles as the cover of the interior of the doors on air bags mounted on the doors. Known smooth textile structures have, in the area of the predetermined separation line, splice edged edges, which are joined together on opposite sides by the seams. The number and strength of the seams are designed so that the smooth textile structures are held together in the normal state and, when the air bag is released, it is opened by the force exerted by the air pocket in the line area of predetermined separation. A disadvantage of known fabrics of this type is the fact that the predetermined separation line is always visible as a seam and is visually unattractive.

DESCRIPTION OF THE INVENTION The fundamental objective of the invention is to create a smooth textile structure, having a predetermined separation line that is invisible from the observation side. In the accomplishment of this objective, a smooth textile structure is provided having a double weave with an upper layer and a lower layer with systems of threads each with warp and weft threads, in which, in the area of the predetermined, desired separation line, a yarn system is provided alternating from the upper layer to the lower layer and a system of yarns alternating from the lower layer to the upper layer, and on both sides of the predetermined separation line, desired , the threads of the thread systems alternating in the area of the predetermined separation line between the upper and lower layer and the upper and lower layer [sic] are separated. Since the threads of each system of threads that alternate from the upper layer to the lower layer and vice versa are cut in each case in front of and behind this alternating point in the area of the lower layer, the separated threads slide together transversely to the predetermined separation line when a force is applied, and continue so until the textile structure flat separates in two parts in the area of the separation line default However, the presence of the predetermined separation line in the normal state is not visible from the upper or visible side of the smooth textile structure. The thread systems alternating from the upper layer to the lower layer and vice versa can be the warp or weft threads. The smooth textile structure can be produced as a double-woven fabric or also as a jacquard fabric, a fabric with uniform colors or patterns and as a fabric with variable textures. After the weaving operation, except for the cutting or separation operation, no other working processes are necessary, such as the gluing and / or sewing of the parts of the fabric. The smooth textile structure of the invention with a predetermined separation line can be used in different ways, for example, as geotextiles in landscape architecture, as coatings for containers, as carrier materials or also as covers for technical components.

DESCRIPTION OF THE DRAWINGS The invention is explained in more detail below with reference to the examples illustrated in the accompanying drawings. These show: Figure 1, a schematic section through a double-woven fabric, with thread systems alternating between the upper layer and the lower layer. Figure 2 is a representation comparable to Figure 1 with a schematic indication of the separation of the yarn systems, alternating between the upper and lower layer and vice versa, in the lower layer. Figure 3 is a representation comparable to the Figure 2 with the schematic illustration of an air bag acting on the smooth textile structure from the side of the lower layer in the area of the predetermined separation line. Figure 4 is a representation comparable to Figure 3 with the predetermined separation line opened by the action of the force exerted by the air bag. A smooth textile structure has an upper layer (1) represented as a scheme and a lower layer (2), also shown schematically. The upper layer (1) has warp threads (3) as well as weft threads (4) and (5). The lower layer (2) has warp threads (6) as well as weft threads (4 ') and (5'). In a comparable mode, the threads of the weft (4 ') alternate between the lower layer (2) towards the upper layer (1) and continue as weft threads (4). To obtain the predetermined, desired separation line, the warp threads (4 ') and (5') in the lower layer (2) are separated on both sides from the area of the predetermined separation line, as indicated by the schematic separation points (10) and (11) and illustrated in Figure 2. the separation points (10) and (11) are not visible when the upper side of the upper layer (1) is observed in the direction of the arrow (A). When, for example, by means of the air bag (13) shown schematically in Figure 3, a force transverse to the plane of the smooth textile structure consisting of the lower and upper layer is applied in the direction of the arrow (B) towards the lower side of the lower layer (2), the separated weft yarns (4) and (5) are pulled towards the lower layer (2) so far that the ends (14) and (15) are completely released from the lower layer , so that an opening action comes in the direction of the arrow (C) along the predetermined separation line. The opening force depends on the density of the fabric, the type of joint, the characteristics of the threads and the construction of the fabric.
