Aspects of the present invention relate to a method (500) of fabricating a cover for an interior trim component or an exterior trim component for a vehicle. The method comprising forming a 3D knitted structure (510) by knitting together at least one heat activated yarn and at least one non-heat activated yarn. The structure may be arranged whereby, during a subsequent heat treatment process (520) in which the cover is heated to a temperature at or above an activation temperature, the heat-activated yarn is activated thereby to form an automotive cover having a knitted structure of increased stiffness once cooled.

Woven material and altering the weave pattern of the woven material. The woven material may comprise a first portion comprising a weave pattern formed by a plurality of warp threads and at least one weft thread woven between the plurality of warp threads. The first portion may have a first thickness. The woven material may also comprise a locally thinned portion positioned adjacent the first portion. The locally thinned portion may comprise an altered weave pattern, which may comprise the plurality of warp threads positioned on a single side of the at least one weft thread, and/or the at least one weft thread woven between the plurality of warp threads in the locally thinned portion is separated by a first distance. The first distance may be greater than a second distance positioned between the at least one weft thread woven between the plurality of warp threads in the first portion.

The present invention relates to an openwork prosthetic knit (1) made from a single piece based on first yarns of biocompatible polymer materials that define a first face (2) and a second face that are opposite one another and on a second biocompatible yarn that generates barbs (3) that protrude outwards from at least said first face, characterized in that said first face comprises at least one zone in which it is provided with said barbs and at least one zone (5) in which it is free of such barbs. It also relates to a process for manufacturing such a knit (1) and to a prosthesis comprising such a knit (1).

The invention relates to a device and a method for the bonding of a textile web, whereby the textile web is guided over an idler drum into a bonding plant, led around a through-air drum and over a cooling drum and then led out again, whereby heated fresh air flows through the web and the through-air drum and the exhaust air is extracted from the bonding plant. According to the invention, it is intended that cooling air is directed onto the web ahead of the detachment point of the web from the through-air drum onto the web.

A fabric (10) for use in composite materials having a reinforcing system (11) made of reinforcing warp threads (13) and reinforcing weft threads (14), which are placed on top of one other in two different reinforcing layers (16), (17). A binding system (12) of binding warp threads (20) and binding weft threads (21) is formed from a binding yarn (30) with a lower yarn count than the reinforcing yarn (15). The reinforcing system (11) is enclosed between the binding warp threads (20) on the one side and the binding weft threads (21) on the other side, and thus, held in place at binding points (22). At each binding point (22), a binding warp thread (20) is guided and held between a stationary warp thread (25) and a regular warp thread (24) of a warp thread pair (23) of binding warp threads (20). Between two adjacent binding points of a warp thread pair (23), the stationary warp thread (25) and the regular warp thread (24) have intersecting points (26).
