摘要： A method and device involve simultaneously inserting weft/binding yarns and beating them up, in textile manufacturing processes like 3D-weaving and uniaxial noobing. A yarn carrier is equipped with a beating-up reed dent. In the carrier, which includes a cartridge-like yarn supplying device, the yarn is arranged around two axes of rotation and it is enclosed in a case. It is particularly suitable for 3D textile-forming processes like 3D-weaving and uniaxial noobing because of its relatively low-height but high-width and hence the possibility of carrying relatively large amount of yarn. The yarn is contained on a flanged belt that can be driven either from within or from the outside. Such a cartridge-like yarn supplier is equipped with tips that are offset or displaced oppositely about the central axis. Such a displaced arrangement of the tips directs the carriers to lay yarn in two different paths, relative to a layer of warp/axial yarns, while traversing back and forth in the same linear path. Through such a method the 3D-weaving and uniaxial noobing processes can be made efficient.

摘要： Novel woven materials, producible by a new weaving method, are described that comprise single or doubled warps and wefts in the form of tapes that are preferably partially stabilized type of fibrous tape. These fibres are caused to occur in a non-linear arrangement during the weaving process. The non-linear fibres can be subsequently straightened by pulling the tape longitudinally. The doubled warps and wefts comprise disconnected tapes. Such separateness of constituent tapes of doubled warp and weft tapes enables them to be slid/slipped relative to each other by pulling longitudinally and laterally without causing any alteration in the woven structure. These novel fabrics solve the problem of uneven fibre distribution and orientation arising from crumples/wrinkles due to compression and stretches due to extension, at the inner and outer sides respectively, when tape-woven fabrics are curved into shapes. Further, by using doubled warps and wefts fabrics with relatively flat/planar sections and thicker/raised wide rib sections can be also created that resemble a bit like a profiled material in its cross-section. Other fabrics like those comprising slant/oblique weft tapes, shaped warp and weft tapes, formed shape within its body are also producible.

摘要： A network-like woven 3D fabric material includes select multilayer warp yarns occurring substantially linearly, the remainder multilayer warp yarns occurring in a helical configuration and two orthogonal sets of weft. This network-like fabric construction is made possible through a dual-directional shedding operation of the weaving process. Such a fabric may additionally incorporate non-interlacing multi-directionally oriented yarns across the fabric cross section to improve the fabric's mechanical performance. The produced 3D fabric material, which may be cut into any desired shape without the risk of splitting, may be used wholly or in parts in technical applications.

摘要： A woven 3D fabric material comprises multilayer axial warp yarns and two orthogonal sets of weft which interlace with the rows and the columns of the warp respectively to provide integrity to the fabric which may additionally incorporate between the rows and the columns of the interlacing warp sets of non-interlacing multi-directionally orientated yarns in the fabric-length, -width, -thickness, and two diagonal directions respectively to improve the fabric's mechanical properties. The interlacing of the multilayer warp and the two orthogonal sets of weft is enabled by a dual-directional shedding means which forms sheds in the row-wise and the column wise directions of the multilayer warp. The produced woven 3D fabric material which may be cut into any desired shape without the risk of splitting up, may be wholly or in parts in technical applications.

摘要： A variety of textile materials comprising tapes oriented in two oblique orientations relative to the textile's length and width directions, called OFT for Oblique Fibre Textiles, are disclosed. Such OFTs are provided with secondary structural integrity/stability, in addition to primary structural integrity/stability, for improved resistance to formation of openings/gaps. OFTs comprising tapes, particularly Spread Fibre and Highly Drawn Polymeric types, are needed in a number of applications such as ballistic mitigation, composite materials, safety products etc. because they provide improved performance, material properties/functions and aesthetics. Such OFTs can be used either independently or in combination with other textile materials. Different types of OFTs are producible by a novel OFT forming process which is technically unlike weaving and braiding processes.

摘要： A novel method of weaving is described wherein warp and weft are supplied in the form of tapes, and not yarns. In at least one embodiment, the method, which is preferably carried out in vertical format, essentially includes feeding positively flat tensionless warp for shedding and taking-up; selecting, feeding positively and inserting weft tapes of different widths and thickness by gripping in its fore end in flat condition; depositing inserted weft at fabric-fell in a flat condition without beating-up; and taking-up the woven material that comprises either same or different widths of flat wefts. The warps and wefts, preferably of partially stabilized type of fibrous tapes, can be overfed in a tensionless, positive and controlled manner when required to make the fibres of constituent fibrous tapes occur non-linearly in the form of wave/texture during weaving. Extra warps and wefts can be also fed in tandem whereby the warps and wefts become composed of two or more unconnected, mutually slipping, flat tapes in a stacked arrangement. These doubled warps and wefts function effectively as a unit warp and weft during weaving and in the fabric. In at least one embodiment, the method also makes possible to produce other materials such as those with slant weft tapes in relation to warp, having a shape within the body of the fabric and warp and weft tapes of shaped edges. A variety of fibrous and non-fibrous materials are equally well processed.
