Definitions

  • the invention relates to a knitted fabric comprising loops or plush loops.
  • the loops or plush loops are adapted to engage in hooks to form a self-gripping hooking device.
  • the knitted fabric comprises a foundation made up of interlacing wale threads and connecting threads without a weft, and a network of loops formed from threads of loops knitted in the foundation of the fabric, the loops inter alia each having a crest and two feet knitted along the wales.
  • knitted fabrics of this kind have a disadvantage, firstly, in that all the loops are formed facing the same direction, i.e. the crest of each loop is always on one side (to the left or right) of the feet of the loop in all the loops in the fabric. This results in less efficient engagement of the hooks of the self-gripping article in one direction than in the opposite direction.
  • the prior-art knitted fabrics also have a second disadvantage in that the percentage of threads used for forming the loops is much lower than the percentage of threads used to form the foundation.
  • the useful engagement part is made up of loops, and consequently it is desirable to use the maximum proportion of thread to form the loops.
  • the invention aims to obviate these two disadvantages simultaneously, i.e. to obtain a knitted fabric having the same hooking capacity as the female part of a self-gripping article in either direction of the fabric (without a weft) and wherein a larger proportion of the threads are used to form the loops, e.g. 40 to 70%, inter alia 50 to 60% of all the threads in the fabric.
  • the looped knitted fabric comprising:
  • a first network of loops knitted in the foundation each comprising two feet knitted in the foundation, two first strands extending from the first feet and a first crest connecting the two first strands, each first crest being on a given side of the two first feet in the case of all the first loops,
  • [0007] is characterised in that it comprises a second network of loops knitted in the foundation, each comprising two second feet knitted in the foundation, two second strands extending from the two second feet, and a second crest connecting the two second strands, each second crest being on the side opposite the said side of the two second feet in the case of all the second loops, and each second foot lying on the imaginary line connecting two first feet of a first loop, between and preferably half-way between the two first feet.
  • each first crest of a first loop is interlaced in a second crest of a second loop.
  • the feet of the loop are formed along the wales.
  • the fabric has a weight between 15 g/m 2 and 150 g/m 2 , inter alia between 15 g/m 2 and 40 g/m 2 , in the case of a thread diameter between 17 and 120 decitex, inter alia between 22 and 70 decitex.
  • the invention also relates to a method of producing a fabric as described hereinbefore.
  • the method of producing a looped fabric on a warp knitting machine comprising rows of needles comprising steps consisting in using three guide bars, a first for forming the chain stitches in co-operation with some needles, a second for forming weft-less connections with the chain stitch-forming needles, and a third for alternately forming meshes (the feet of the loops) on one row of chain stitch-forming needles and meshes (the crests of the loops) on the needles between two consecutive rows of chain stitch-forming needles, is characterised in that at least two rows of loop crest-forming needles are provided between two consecutive rows of chain stitch-forming needles and the third bar acts on two threads so as to knit at least two networks of loops between two consecutive rows of chain stitch-forming needles, the two threads being offset by a spacing corresponding to the distance between two rows of needles on the loom.
  • a 10-23 weave is used for the third bar.
  • a 10-45 weave is used for the third bar.
  • the invention also relates to a laminated assembly comprising a fabric according to the invention fixed to a support, inter alia by pasting.
  • the invention relates to a laminated assembly having a support in the form of a pilch.
  • the invention relates to a pilch comprising a self-gripping female part comprising a fabric according to the invention.
  • FIG. 1 diagrammatically shows the production of a looped fabric according to the invention, using a 10-23 weave for the third bar;
  • FIG. 2 diagrammatically shows production of a second looped fabric according to the invention using a 10-45 weave for the third bar;
  • FIG. 3 is another diagrammatic view of production of a looped fabric according to the invention, the wales being separated by three rows of needles instead of two in FIGS. 1 to 2 , using a 10-34 weave for the third bar, and
  • FIG. 4 is a diagram showing production of another looped fabric according to the invention, the wales in this case being separated by three rows of needles instead of two in FIGS. 1 and 2 and a 10-56 weave being used for the third bar, and
  • FIG. 5 shows a pilch according to the invention comprising the self-gripping part according to the invention.
  • the method of producing a looped fabric on a warp knitting machine illustrated by the diagram in FIG. 1 consists in working with three guide bars.
  • a first bar forms the chain stitches 1 in co-operation with a row (vertical in the drawing) of needles out of three in the example under consideration.
  • a second guide bar forms the weft connections 2 in cooperation with chain stitch-forming needles 1 .
  • Finally a third bar alternately forms meshes 3 and 3 ′ (the feet of the loops) on the chain stitch-forming needles in one row and meshes corresponding to the loop crests 4 , 4 ′ on the two rows of needles situated between two consecutive rows of chain stitch-forming needles.
  • the weft connection here is represented by a non-meshed (picked) system; however a meshed system or a varying system are also possible.
  • the chain stitches or wales can be open, closed or alternating (two meshes in one direction, two in another).
  • the fabric on a loom shown in FIG. 1 also comprises two networks of plush loops, i.e. a first network of loops comprising feet 3 and loop crests 4 and a second network of loops comprising feet 3 ′ and loop crests 4 ′.
  • the guide bar C for forming the loops knits all the loops in the same direction of advance of the fabric on the loom. However it acts on two threads offset by the distance between two adjacent rows of needles and, since two rows of needles have now been left free between two consecutive rows of chain stitches, the two networks of loops face in opposite directions, i.e. in FIG.
  • a foot 3 ′ of a loop 4 ′ extends along a chain stitch 1 between two feet 3 of the first network of loops.
  • the foot 3 ′ in question is halfway between two feet of a first neighbouring loop.
  • the gill bar C for forming the loops travels in accordance with a 10-23 weave.
  • the needles (represented by points in FIGS. 1 and 2) are distributed over the loom in a matrix having lines (horizontal in the drawing) and columns or rows (vertical in the drawing), the columns or rows being numbered starting from 0.
  • the cycle travelled by the gill bar C is as follows.
  • the bar unravels a first thread in a needle in one of the two rows of needles situated between rows of wale or chain stitch needles (column 1 ) to form a crest of a second loop, then meshes a second thread in a needle where a wale (column 0 ) has already been meshed, to form a loop foot for each mesh.
  • the gill bar unravels the second thread in a needle in the other of the two rows (column 2 ) to form a crest of the first loop and meshes the second thread in the next wale (column 3 ) to form a foot of a second loop.
  • FIG. 2 shows another embodiment substantially identical with that in FIG. 1.
  • the loops in the first network interlace at their crests 4 with the loops in the second network at the level of their crests 4 ′.
  • the loops here are larger since when the interlaced loops are withdrawn from the loom, they retain a greater length than in the embodiment in FIG. 1.
  • the loop bar C for knitting the two networks of loops follows a 10-45 weave.
  • FIG. 3 shows a fabric looped on a loom identical with that in FIG. 1 except that the wales or chain stitches 1 are separated by three rows of needles instead of two.
  • the bar C therefore follows a weave 10-34.
  • FIG. 4 shows a fabric looped on a loom identical with that in FIG. 2 except that the chain stitches 1 are separated by three columns or rows of needles instead of 2.
  • the bar C therefore follows a weave 10-56.
  • FIG. 5 shows a pilch 5 comprising a self-gripping device comprising a female part 6 in the form of a knitted fabric according to FIG. 1 or 2 pasted to a support which in turn is pasted or heat-sealed or fixed in any other manner to the edge of the pilch, which can be fastened by means of the self-gripping device and the male part 7 situated on the other edge.
  • a self-gripping device comprising a female part 6 in the form of a knitted fabric according to FIG. 1 or 2 pasted to a support which in turn is pasted or heat-sealed or fixed in any other manner to the edge of the pilch, which can be fastened by means of the self-gripping device and the male part 7 situated on the other edge.
