Abstract:
A woven article (100') having plural weave layers comprises a plurality of electrically insulating and/or electrically conductive yarn in the warp (110, 120) and a plurality of electrically insulating and/or electrically conductive yarn in the weft (130, 140, 140a, 140b) interwoven with the yarn in the warp. An electrical function is provided by one or more circuit carriers disposed in cavities (106a, 106b) in the plural layer woven article and/or one or more functional yarn (150) in the warp and/or the weft, wherein the circuit carrier and/or functional yarn include an electrical contact for connecting to the electrically conductive yarn in the warp and/or weft.
Abstract:
The present invention is directed to a textile fabric (10). This fabric is particularly well suited for use as the outer shell fabric of spun yarns (12) and multi-filament yarns (14). The spun yarn (12) includes a first staple being a polymer selected from the group consisting of PBI or PBO or melamine formaldehyde, and a second staple being an aramid filament.
Abstract:
A woven industrial fabric, including a plurality of warp yarns 20 interwoven with a plurality of weft yarns 22. At least a portion of one of the plurality of warp 20 and the plurality of weft 22 yarns includes yarn assemblies 12. Each yarn assembly 12 is comprised of at least a first 14a and a second 14b yarn. The yarns 14a, 14b are structured and arranged in the woven fabric so as to be in generally continuous, contiguous contact with each other substantially throughout the fabric.
Abstract:
The invention concerns a reinforced fabric comprising on its front surface a warp yarn weave (2) in one direction and a weft yarn weave (3) in the perpendicular direction or a mesh-type weave. Furthermore, said fabric comprises on its rear surface a reinforcing grid consisting of warp yarns (4) and weft yarns (5) produced in a material having different properties, such as higher mechanical properties than those producing the yarns of the front surface, the reinforcing grid being linked to the front surface by its warp and weft yarns, the warp yarns (4) and the weft yarns (5) being fixed on the front surface in different points and intersecting outside the ground fabric forming the front surface.
Abstract:
A method of weaving tubular textile articles, comprising: forming first, second, third and fourth superposed layers of warp threads; weaving by weft insertion through sheds formed in said layers, the weaving being performed by first and second weft threads inserted by first and second needles from one side of said warp layers; each weft thread being inserted alternately through a selected pair of said warp layers; and the weft loops at the other side of said layers being knitted together, the first layer with the second layer and the third layer with the fourth layer, to form a pair of selvedges. A tubular textile article formed by the method is provided. A needleloom for weaving such articles is also provided.
Abstract:
An on-machine-seamable press fabric for the press section of a paper machine includes a multi-layered integrally woven base fabric having two systems of machine-direction yarns (32, 34) forming seaming loops (42, 44) along each of its two widthwise edges. A seaming spiral (52) is attached to the seaming loops in both rows at each of the two widthwide edges. The two seaming spirals are used to join the press fabric into endless form during installation on the press section of a paper machine.
Abstract:
The patterned scarf is made up of a first and a second layer of fabric (2, 4) which are interwoven at the edges (6, 8). The scarf has colours and/or patterns which are formed with weft threads (12) by spaced out insertions between warp threads (10) of the same colour. The warp threads (10, 10a, 10b, 10c) consist of a textured yarn consisting of chemical fibres, in order to improve the appearance of the fringes (14) at the transverse edges (8).
Abstract:
A base material for use in a printed circuit board, the base material formed from a three dimensional woven fabric (10) having a crimp-free fiber architecture in an x-y plane, the base material comprising a first system of straight first fibres (X) extending along a first direction in a first plane, a second system of straight second fibers (Y) extending along a second direction in a second plane parallel to the first plane, a third system of third fibers (Z) extending along a third direction through the first and second systems and binding the first and second fibers thereof, and a filler material coating at least a portion of the first, second, and third systems.
Abstract:
The invention relates to a reinforcing structure (13), comprising metallic elements (15) (16), to be used to reinforce stiff composite articles (14) comprising such reinforcing structure and a polymer matrix. The reinforcing structure comprises metallic elements with structural deformations in order to improve the bending properties of the reinforcing structure and the impact properties of the stiff composite article, for which the reinforcing structure is used. The metallic elements run essentially parallel to each other.
Abstract:
The invention relates to a reinforcing structure, comprising metallic elements, to be used to reinforce stiff composite articles comprising such reinforcing structure and a polymer matrix. The reinforcing structure comprises metallic elements (201, 202) which are part of a textile fabric. The metallic elements have at least one structural deformation, other than the deformation they have due to their presence in the textile fabric. This additional structural deformation improves the bending properties of the reinforcing structure and the impact properties of the stiff composite article, for which the reinforcing structure is used.
