Definitions

  • This invention relates to a method for simultaneously weaving two pile fabrics with shadow cut pile zones on a face-to-face weaving machine.
  • This invention also relates to a pile fabric with shadow cut pile zones, which can be woven with such a method.
  • weft yarns are bound in the backing fabrics on two different levels: inner weft yarns are inserted on the pile side of the tension warp yarns and back weft yarns are inserted on the other side of the tension warp yarns.
  • Each opening of the binding warp yarns includes only one weft yarn.
  • a pile leg slants to the right side if it burls around an inner weft yarn which immediately follows another inner weft yarn or if it burls around a back weft yarn which follows two inner weft yarns.
  • a change in the slanting direction of the pile yarns requires a modification of the ground binding.
  • the binding warp yarns are driven by a cam machine or a dobby. With such a configuration, it is not possible to create bi-dimensional patterns with pile yarns with different slanting direction along the weft direction.
  • the pile legs orientation can only be changed on the whole width of a fabric, by varying the backing fabric weave structure, which creates strips of differently oriented piles, but no freely designed shadow effect zone.
  • EP-A-2894244 solves this problem with a method where a shadow effect results from the way patterning pile yarns are bound in a backing fabric. Since patterning warp yarns are driven by a Jacquard machine, a fabric with various patterns, such as flowers, can be obtained. This method is globally satisfactory. However, the slanting effect obtained with some kinds of warp yarns might be not significant enough to provide a clear shadow effect.
  • This invention aims at solving this problem with a new method for simultaneously weaving two pile fabrics including shadow cut pile zones clearly visible and adjustable both in the warp direction and in the weft direction of the fabric.
  • the invention relates to a method for simultaneously weaving two pile fabrics with shadow cut pile zones on a face-to-face weaving machine, wherein an upper backing fabric and a lower backing fabric are woven one above the other with at least one filling warp yarn, at least one binding warp yarn, weft yarns inserted in successive weft insertion cycles between binding warp yarns and filling warp yarns, the weft yarns comprising inner weft yarns, which are inserted on a pile side of the filling warp yarns, and back weft yarns, which are inserted on a back side of the filling warp yarns, opposite to the piles of the fabric.
  • patterning pile yarns are interlaced in the upper backing fabric and in the lower backing fabric, each patterning pile yarn turning externally around an inner and a back weft yarns in each backing fabric.
  • weft yarn groups made of an inner weft yarn, a back weft yarn and another inner weft yarn, are inserted in at least one backing fabric, in successive weft insertion cycles, and at least one patterning pile yarn follows a path where:
  • a first and a second weft yarns are consecutive in a backing fabric when, in a warp direction, these first and second weft yarns extend next to each other, with no other weft yarn located between these two weft yarns.
  • a consecutive second weft yarn is a weft yarn which is next, in the warp direction, with respect to a first or reference weft yarn.
  • the slanting direction of one pile yarn can be changed when passing from the first series of weft insertion cycles to the second series of weft insertion cycles, as in EP-A-2894244 .
  • This allows weaving a carpet with shadow zones in which the pile yarns directions can vary along the warp direction and along the weft direction.
  • the path of the patterning warp yarn in the first series of weft insertion cycles, where this warp yarn turns externally around an inner weft yarn, then internally around another inner weft yarn, then externally around a back weft yarn allows obtaining a more noticeable slanting effect of the pile tufts once they have been beaten by the reed and cut.
  • the expression « turns externally » means that a pile yarn “turns”, “winds” or “burls” around a weft yarn, which belongs to a backing fabric, on a side of this weft yarn which is oriented opposite to the backing fabric of the other pile fabric simultaneously woven with the one to which the weft yarn belongs.
  • the expression “turns internally” means that a pile yarn “turns”, “winds” or “burls” around a weft yarn, which belongs to a backing fabric, on a side of this weft yarn which is oriented towards the backing fabric of the other pile fabric.
  • such a weaving method may incorporate one or several of the following features, considered in any technically allowable combination:
  • This invention also relates to a pile fabric with shadow cut pile zones, this fabric comprising a backing fabric woven with yarn sets including at least one filling warp yarn, at least one binding warp yarn and weft yarns located between the binding warp yarn and the filling warp yarn, the weft yarns comprising inner weft yarns which are located on a pile side of the filling warp yarn and back weft yarns which are located on a back side of the filling warp yarn, opposite the piles of the fabric.
  • This fabric also includes pile tufts corresponding each to a patterning pile yarn, belonging to a yarn set, interlaced in the backing fabric and forming two pile legs.
  • weft yarn groups are made of an inner weft yarn, a consecutive back weft yarn and another consecutive inner weft yarn and for at least one yarn set, at least a first pile tuft and a second pile tufts, which are offset with respect to each other in a warp direction of the fabric, are interlaced in the backing fabric in a configuration where:
  • the pile fabric includes two binding warp yarns used to bind the weft yarns to the filling warp yarn and the patterning pile yarn of a yarn set whereas all weft yarns of a weft yarn group go through an opening formed by the two binding warp yarns.
  • the pile fabric includes two binding warp yarns to bind some weft yarns to the filling warp yarn and, for a first yarn set, the binding warp yarns follow a pattern which ties some weft yarns to the filling warp yarns whereas, for second yarn set adjacent to the first yarn set, the binding warp yarns follow a pattern which ties at least some other weft yarns to the filling warp yarns.
  • Figure 1 is a schematic cross-section, in the warp direction, of two carpets C1 and C2 simultaneously woven one above the other on a face-to-face weaving machine or loom, with two non represented insertion means.

  • binding warp yarns b2 and b2' and filling warp yarn f2 together form a group of warp yarns devoted to backing fabric F2.
  • Binding warp yarns and filling warp yarns are drawn in through heddles which are mounted in heddle frames connected to a non represented shedding device, such as a dobby or a cam machine.
  • Pile warp yarns I to III, PY and VI to VIII are fed from a creel and drawn in through heddles connected to a non-represented Jacquard machine.
  • a top shed is defined between some warp yarns placed by their respective heddles into a top position and a middle position.
  • a bottom shed is defined between some warp yarns placed by their respective heddles into a middle position and a bottom position.

  • This direction is represented on figure 2 with arrow DE, whereas arrow DA represents a warp direction perpendicular to weft direction DE.
  • Warp direction DA is also represented on figure 1 .
  • Directions DA and DE oriented. In particular, direction DA goes from pick P1 towards pick P32.

  • All the warp yarns represented on figure 1 that is binding warp yarns b1, b1', b2 and b2', filling warp yarns f1 and f2 and pile warp yarns I to II, III, PY and VI to VIII belong to the same set of warp yarns.
  • one weft yarn is inserted into backing fabric F1 and one weft yarn is inserted into backing fabric F2 by two non represented insertion means which travel into the top and bottom sheds.
  • This insertion means can include rapiers or any similar device.
  • Weft yarns include inner weft yarns Wi which can also be called “front” weft yarns, since they are oriented, with respect to backing fabric F1 or F2, towards the front of carpet C1 or C2, that is towards median plane ⁇ 0.
  • Weft yarns also include back weft yarns Wb which can also be called “outer” weft yarns, since they are oriented towards the outside of a space defined between backing fabrics F1 and F2 in the configuration of figure 1 .
  • Inner weft yarns Wi are located, in each backing fabric on the same side as the piles D1 or D2 with respect to the filling warp yarn f1 or f2.

  • a pick sequence is defined by picks P1 to P6 and this sequence is repeated for picks P7 to P12 and starts again with pick p13.
  • a first series of weft insertion cycles is formed by picks P1 to P13. In this first series of weft insertion cycles, each pick where two outer weft yarns Wb are inserted into backing fabrics F1 and F2 is followed by two picks where tow inner weft yarns Wi are inserted into these fabrics.
  • patterning pile yarn PY follows a three pick binding path within each backing fabric F1 or F2. More precisely, patterning pile yarn PY turns externally around a first inner weft yarn Wi of backing fabric F1, at picks P5 and P11, before it turns internally around a second consecutive inner weft yarn Wi, at picks P6 and P12. Then, patterning pile yarn PY turns externally around a back weft yarn Wb of backing fabric F1, at picks P7 and P113.
  • patterning pile yarn PY turns externally around a first inner weft yarn Wi, at picks P2 and P8, prior to turning internally around a second consecutive inner weft yarn Wi, at picks P3 and P9, and then turning externally around a back weft yarn Wb, at picks P4 and P10.
  • patterning warp yarn PY leaves the backing fabric where it has been previously turning around two inner weft yarns Wi and crosses the empty space between backing fabrics F1 and F2 in order to enter the other backing fabric, as shown, for example, between picks P4 and P5 or between picks P7 and P8.
  • patterning pile yarn PY forms successive loops which includes two legs that will form pile D1 or D2 once cut by knife K.
  • each loop, formed by patterning pile yarn PY during picks P1 to P13 successively goes around one inner weft yarn Wi, on the outer or external side of this weft yarn, around another inner weft yarn Wi, on the inner or internal side of this weft yarn, and around one back weft yarn Wb, on the outer or external side of this weft yarn.
  • Picks P14 to P18 together constitute a transition series of weft insertion cycles where patterning weft yarn PY follows a V shaped binding in each backing fabric F1 or F2.
  • patterning yarn PY starts again to follow a three picks binding path in each backing fabric, with a path different from the one used in picks P1 to P13.
  • patterning yarn PY turns first around a back weft yarn Wb, then internally around a first consecutive inner weft yarn Wi and then externally around a second consecutive inner weft yarn, in three consecutive picks, as shown by picks P19 to P21 in top backing fabric F1 and by picks P22 to P24 in bottom backing fabric F2.
  • patterning warp yarn PY leaves the backing fabric where it has been previously turning around the outer weft yarn Wb and the first inner weft yarns Wi and crosses the empty space between backing fabrics F1 and F2 in order to enter the other backing fabric, as shown, for example, between picks P21 and P22 or between picks P24 and P25.
  • the piles D1 and D2 formed by patterning pile yarn PY take two different slanting orientations once fabrics F1 and F2 have been beaten by the reed and separated from each other by knife K.
  • portion PY.1 of yarn PY which has been woven in backing fabric F2 between picks P10 and P11, forms a tuft or loop with two piles D2 slanted in the direction of arrows A1.
  • portion PY.1 is a patterning individual pile tuft of carpet C2 which, along warp direction DA turns externally around inner weft yarn Wi inserted at pick P8, then internally around inner weft yarn Wi inserted at pick P9 before it turns around back weft yarn Wb inserted at pick P10.
  • portion PY.2 of yarn PY which has been woven in backing fabric F2 at picks P22 to P24, forms a tuft or loop with two piles slanted in the direction of arrows A2.
  • Portion PY.2 is a patterning individual pile tuft of carpet C2 which, along warp direction DA, turns externally around back weft yarn Wb inserted at pick P22 before it turns internally around inner weft yarn Wi inserted at pick P23 and the externally around inner weft yarn Wi inserted at pick P24.
  • Pile tufts PY.1 and PY.2 are offset with respect to each other along warp direction DA.
  • This change of the slanting orientation of the piles D1 and D2 is obtained without changing the weave patterns of the binding warp yarns b1 and of the filling warp yarns f1 and f2, which remain the same between picks P1 and P32.
  • the backing fabric ground weave structure remains the same for each backing fabric F1 and F2, for all picks.
  • the BFWR remains equal to six.
  • the change of the slanting orientation of piles D1 and D2 along warp direction DA can be obtained by individually driving patterning pile yarn PY via the Jacquard mechanism, which means that adjacent pile yarns in the weft direction DE can have different configurations and switch from a first slanting orientation to a second slanting orientation at different locations along the warp direction DA.
  • patterning pile yarn PY follows a path where, in each backing fabric F1 and F2, the binding path of picks P5 to P7 in backing fabric F1 or the binding path of picks P2 to P4 in backing fabric F2 is implemented twice before the slanting direction of the piles D1 and D2 is changed. Similarly, the binding path of patterning pile yarn PY is repeated twice in each backing fabric as from pick 19. In practice, in order for the change in the slanting direction or orientation of the piles to be easily visible, the patterning pile yarn PY follows such a patterning path twice or more in each backing fabric, both during the first series of weft insertion cycles and during the second series of weft insertion cycles.
  • each carpet at least four consecutive pile tufts PY.1 turn externally around a first inner weft yarn Wi prior to turning internally around a second inner weft yarn and to turning externally around a consecutive back weft yarn Wb.

  • a weft yarn group can be defined by three weft yarns successively introduced within one backing fabric F1 or F2 during three successive picks.
  • successive weft yarn groups G1 are formed, which include an inner weft yarn Wi, an outer weft yarn Wb and another inner weft yarn Wi, inserted consecutively, in this order, within the shed.
  • a group G1 is formed by weft yarns inserted into the top shed during picks P3 to P5 or during picks P21 to P23.
  • successive weft yarn groups G2 are formed, which include an inner weft yarn Wi, an outer weft yarn Wb and another inner weft yarn Wi, inserted consecutively, in this order, within the shed.
  • a group G2 is formed by weft yarns inserted into the bottom shed during picks P3 to P5 or during picks P21 to P23.

  • Each weft yarn group G1 is inserted in a single opening O1 and each group G2 is inserted in a single opening 02.
  • all weft yarns are firmly held in position within backing fabrics F1 and F2.

  • the slanting effect is obtained by inner weft yarn Wi inserted at pick PN acting on pile tufts PY.2 formed between picks PN and PN+1, for N equal to 21, 24, 27 and 30.
  • the face-to-face weaving machine used with these methods also has two non represented insertion means, a first shedding device, for instance a dobby, which can move the binding and filling warp yarns between two positions, and a second shedding device, for instance a Jacquard mechanism, which can move the pile yarns between three positions.
  • a first shedding device for instance a dobby
  • a second shedding device for instance a Jacquard mechanism
  • the patterning weft yarn PY follows the same path as in the first embodiment.
  • the ground weave structure is changed in order to achieve a greater density in the warp direction DA. More precisely, one defines a set of warp yarn as in the first method and, for such a set of warp yarns, the binding pile yarns b1, b1', b2 and b2' follow a path where they bind together only some of the weft yarns Wi and Wb with the filing warp yarns f1 or f2. In the example of figure 3 , between picks P1 and P13, only warp yarns Wi and Wb inserted at picks P1, P2, P4, P7 and P9-P14 are bound to backing fabric F1.
  • Warp yarns Wi inserted at picks P3, P5, P6 and P8 are bound to backing fabric F1 in the adjacent set of warp yarns, that is in the set of warp yarns going through a reed dent adjacent to the one through which the warp yarns visible on figure 3 go through. This also applies for the transition series P14 to P18 and for the second series of weft insertion cycles P19 to P32.
