WEAVING MACHINE, METHOD FOR SIMULTANEOUSLY WEAVING TWO PILE FABRICS ON SUCH A MACHINE AND PILE FABRIC OBTAINABLE WITH SUCH A METHOD
This weaving machine (2) is for simultaneously weaving a top pile fabric (F2) and a bottom pile fabric (F4), each pile fabric presenting some pile patterns (P2, P2, P4) and including tufts, made from warp yarns (24), binding warp yarns (14, 16) and inwoven weft yarns. This machine comprises a pile warp yarns feeding unit (20), a binding warp yarns feeding unit (18), a shedding unit (6) for creating a shed with the pile warp yarns and the binding warp yarns (14, 16). A weft insertion unit (8) is used for inserting the weft yarns in the shed in successive insertion cycles. A beating-up mechanism (32) is used for beating the weft yarns into the shed. A take up system (70) is used for taking-up the two pile fabrics. A drawing-in unit (26) draws the pile warp yarns from the pile warp yarn unit (20) and a control unit (80) controls operation of the weaving machine (2). This weaving machine also comprises a treatment unit (90) located, along a path of the pile warp yarns (24), between the pile warp yarns feeding unit (26) and the shedding unit (6), for applying different segments of treatment on at least some of the pile warp yarns (24).
Heat sink with carbon-nanostructure-based fibres
The invention relates to a heat sink (1) having a main body (2) and a plurality of carbon-nanostructure-based fibres (CNB, 3), more particularly carbon nano tubes (CNT, 4) or graphene fibres, of which at least some are attached to the main body (2). According to the invention, the fibres (3, 4), by adhering to or supporting one another, form a volume structure (12), more particularly in the manner of cotton wool, felt or a spun yarn, or the fibres (3, 4) form loops (6) or a three-dimensional woven fabric.
Carpet having a shadow effect and method for weaving a carpet fabric having a shadow effect
A carpet having a shadow effect comprises a backing fabric having weft threads (S) and tension warp threads (S1, S2), further comprising pile warp threads (P) interlaced with the weft threads (S) of the backing fabric and forming pile elements, the weft threads (S) being provided in groups (G) of weft threads repeatedly appearing in a warp direction, each group (G) of weft threads providing a relative positioning of the weft threads (S) thereof relative to at least one tension warp thread (S1, S2), a weft thread (S) of a group (G) being either positioned on a pile side relative to a tension warp thread (S1, S2) or on a back side relative to this tension warp thread (S1, S2) in a respective relative positioning, a first group (G1) of weft threads having a first relative positioning of the weft threads (S) thereof and a second group (G2) having a second relative positioning of the weft threads (S) thereof different from the first relative positioning, wherein the first relative positioning and the second relative positioning provide a substantially mirror-symmetrical arrangement with respect to each other relative to a plane of symmetry (Sy1) extending in the weft direction, and/or wherein in the first relative positioning and the second relative positioning weft threads (S) positioned at a first group end region (E1) in the warp direction and weft threads (S) positioned at a second group end region (E2) in the warp direction have a different relative positioning with respect to at least one tension warp thread (S1, S2).

FABRIC, IN PARTICULAR CARPET, AND METHOD OF WEAVING A FABRIC
A fabric (e.g., carpet having a shadow effect) includes a backing fabric having binding warp yarns repeatedly crossing each other for providing weft receiving openings, tension warp yarns substantially extending in a warp direction, and weft yarns substantially extending in a weft direction through the weft receiving openings, pile warp yarns interlaced with weft yarns for providing piles extending out of the backing fabric, wherein, at least one weft yarn is positioned immediately adjacent to one of the crossings of the binding warp yarns provides an end weft yarn positioned at a back side relative to at least one weft separating warp yarn extending in the backing fabric substantially in the warp direction, and at least one intermediate weft yarn positioned adjacent to such an end weft yarn in the warp direction is positioned at the pile side.

METHOD FOR FACE-TO-FACE WEAVING OF FABRICS WITH FIGURE WARP THREADS
A method for face-to-face weaving of two at least partially pile-free fabrics (I), (II) in which weft threads (101-104),(201-204) are inserted between warp threads (1a-14a,1b-14b) of warp thread systems with figure warp threads (1a-8a),(1b-8b) that are allocated to respective fabrics (I,II) and are either pattern-determining in that fabric or are incorporated therein, whereby at least one set (1a,1b), . . . (8a,8b) of two identical figure warp threads is provided per pair of neighbouring warp thread systems, while the two figure warp threads of each set belong to a different warp thread system (1a-14a), (1b-14b) and are allocated to a different fabric (I,II), so that each set of figure warp threads per pair of neighbouring warp thread systems provides a figure warp thread in both fabrics (I,II) to determine the pattern.
