摘要:
The present invention refers to an impact-resistant and penetration-resistant textile structure (100), to a method and to an apparatus for production thereof, wherein the textile structure comprises a first bundle of unidirectional threads (101), which are arranged parallel to each other on the same first plane, and a second bundle of unidirectional threads (102), which are arranged parallel to each other on the same second plane, wherein the first plane and the second plane are overlapped each other with the threads (101) of the first bundle oriented at 90° +/-50 with respect to the threads (102) of the second plane and wherein between the first plane and the second plane is interposed at least one intermediate layer (106), and it is characterised in that the threads (101) of the first bundle, also differing in nature and/or count, are joined to the threads (102) of the second bundle, also differing in nature and/or count, by knit stitching traversing the intermediate layer and in such a manner that an n-number of said threads (101) of the first bundle is joined by knit stitching to an equal n-number of said threads (102) of the second bundle, and in that the coverage factor referring to the threads (101, 102) of the first and second bundle is less than 100%, with a uniform and symmetrical distribution of the discontinuity coverage areas (104) on the first plane and on the second plane, wherein the volume of the discontinuity coverage areas (104) is reduced by at least 5% with respect to the initial volume after pressing and wherein le discontinuity coverage areas (104) act as cavities for collecting and distributing at least one polymeric substance present in or applied to the threads, and/or to the intermediate layer and/or to the structure, after pressing.

摘要:
The subject invention comprises a flexible multilayer fire-rated material that has at least one layer of an intumescent material. Because it is flexible, the fire- rated material is usable in situations where it is desirable for the fire-rated material to be rolled up or folded into a non-flat storage application. This allows the subject fire- rated material to be used in fire-rated and smoke-resistant barriers that are recessed in walls or ceilings until use. One end use embodiment includes without limitation, recessed or rolled up fabrics used in elevator lobby ceilings to seal off elevators or their lobbies from smoke or fire.
摘要:
Non-woven layer having a first and second, generally opposed major surfaces, a length with first and second, generally opposed edges, wherein the non-woven layer comprising inorganic fibers and having a binder content not greater than 7 percent by weight, based on the total weight of the non-woven layer, wherein there is at least one line of stitching. The non-woven layer is useful, for example, for mounting mats for pollution control devices.

The invention relates to the reinforcement of sandwich structures by means of a reinforcement device. The cover layers can be made of fiber-plastic composites and the sandwich material of polymer high-resistance foam. The introduction of a through-hole in the sandwich material is carried out at a different time than the introduction of the reinforcement structure. After introducing the though-hole by means of a hook, gripper or needle, the reinforcement structure is fetched and introduced into the sandwich structure by an upward movement. Then the needle, the gripper or the hook is guided to the next infeed hole in the stitching direction, wherein the upper and lower reinforcement structures get intertwined.

Methods for making a self-conforming non-crimp fabric involving tailoring at least a first parameter to anchor the fabric and at least a second parameter to provide conformability of the fabric, the first and second parameters selected from stitch type, stitch spacing, stitch density, stitch material, stitch weight, stitch tension, and combinations of the same.
摘要:
An apparatus and method for making a trim panel. The method includes providing a preform laminate including a compressible material sandwiched between a flexible skin and a back skin. Positioning the preform laminate in the mold. Placing an insert with the preform laminate in the mold to created a step to establish a seam location and define a secondary area on the preform laminate. Compressing the compressible material by introducing a molten polymeric material to the mold forming a substrate and bonding the substrate to the preform laminate forming the trim component. The preform laminate folds onto itself and creates a crease along the step to simulate the seam and provide a contour change with the appearance of cushioning in the secondary area, and removing the trim panel component from the mold.
摘要:
A stitchbonded fabric has a regionally segmented discontinuous base layer of webs of substrate material extending in the machine direction which webs are laterally separated by a region devoid of substrate material. The lateral separation in the stitchbonded fabric is formed prior to stitching by a method that includes slitting the substrate and folding the material adjacent the slits outwardly in contact with substrate material outboard of the slit, or by a method that includes slitting the substrate while applying tension.
