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.

A method for simultaneously weaving, on a face-to-face weaving machine, two pile fabrics each including an area with and without pile. For a pick corresponding to the area without pile, a dead pile thread is placed between the backing fabric and a patterning weft and a dead pile thread is placed opposite the backing fabric with respect to the same patterning weft. An additional fabric is formed in the area without pile by the first and second dead pile threads woven with the patterning wefts, this additional fabric covering the backing fabric.

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.

A pile knit fabric for internal materials of vehicles may include a knit layer prepared by weaving ground yarns, on one surface thereof, and a pile layer prepared by interweaving pile yarns with ground yarn loops of the knit layer, on the other surface thereof and, thus, has excellent physical coupling force between the ground yarns and the pile yarns and has excellent abrasion resistance, scratch resistance and formability as well as soft tactility.

A fabric includes a backing fabric having binding warp yarns, weft yarns, and pile warp yarns interlaced with the weft yarns. In a weft receiving opening, one of the weft yarns is positioned at a back side relative to a weft separating warp yarn extending in the backing fabric in the warp direction and the other weft yarn is positioned at the pile side. A pile warp yarn is interlaced with the weft yarn positioned at the back side relative to the weft separating warp yarn to extend out of the backing fabric between this weft yarn and the other weft yarn. In a transition zone, two transition weft yarns provided immediately adjacent to each other in the warp direction extending through a weft receiving opening are positioned at substantially the same level in a direction that is perpendicular with a plane defined by the warp and weft directions and/or are not separated by a weft separating warp yarn.

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).
