Definitions

  • ABSTRACT A textile fabric which consists of a warp knitted fabric [52] [1.5. Cl.........................66/l92, 66/195, 139/1 R .D04b 23/00 .66/192, 190, 195,
  • Woven fabric provides, amongst other things, a better dimensional stability in inelastic as well as in elastic fabrics. Warp knitting provides a more aerated fabric and a higher production.
  • the present invention provides a textile fabric comprising in combination first warp threads and second warp threads, said second warp threads being warp knitted together to form wales and the underlaps of the second warp threads between said wales forming the weft with which said first warp threads are woven.
  • FIG. 1 graphically represents the intersection of the threads of a traditional warp and weft fabric with plain weave
  • FIG. 2 graphically represents the thread intertwining in of a conventional warp knitted fabric in which each two wales are knitted together
  • FIG. 3 graphically represents one of the many combinations of the application of the present invention
  • FIG. 4 graphically represents apparatus for carrying out the present invention.
  • the present invention is characterized by the combination (FIG. 3) of:
  • Warp threads a running in the longitudinal direction of the cloth in the manner of the warp threads on wellknown weaving looms and intertwined in accordance with one of the possible weaves, including leno weave," either intermittently or constantly, whatever their number, thickness, material or color, regularly or not regularly spaced from one another.
  • FIG. 3 comprises a strip with three threads and a strip with four threads.
  • the weave used in this embodiment is a plain weave in which each warp is alternatively overcrossed and undercrossed by two of the knitting thread sections that interconnect two wales but it could be different as well, knitting warp threads b, in one or several layers, as known in relation to warp knitted fabrics, in which each thread is formed in loops on two wales interconnected by so-called bridging sections, whatever their type of binding and the length of the overcrossing" and undercrossing bridging sections, coming from one or several warping beams or even from individual bobbins, spaced and interlaced uniformly or not, with open or closed loops, whatever the material they are made from, their count, colors or physical and chemical properties.
  • warp threads b have the particular feature, when formed in loops on two wales, of binding simultaneously said wales in a fabric-like manner, by means of the bridging sections that may interconnect adjacent or not adjacent wales, or wales, differently spaced, depending on. the binding design.
  • the bridging sections interconnect two adjacent wales, but in FIG. 3 they interconnect two wales separated by another wale and it is quite possible to have in the same fabric bridging sections as in FIG. 2 and/or quite different ones. realization is that the wales be connected to each other.
  • any other connection effected on warp or Rachel looms for example two layers of warp b, one making the stitch on a single line (chain stitch) and the other ensuring the connection either by producing a stitch or by being simply held to the heads of the stitches.
  • the present invention also includes the complementary use of a core thread, that is not formed in loops, does not form bridging sections but is fastened to the top of the loops in the manner of an elastic yarn in the elastic knitted net fabric.
  • the combination of connections used for these threads b must'comprise a certain number of underlaps which are destined to serve as weft for the threads a.
  • the fabric as described above may include other additional elements such as warp and weft of plush or velour, the second fabric being super-imposed with the pile adapted to obtain velours, carpet fabrics or moquettes or simply in a tubular manner whatever the length, with plain or intermediate connections which create continuous or intermittent channels or piping, with the incorporation of fibers, down, which may be expanded, glued, quilted or hooked, in layers or otherwise, or the fabric may also be completed by means of other additions.
  • additional elements such as warp and weft of plush or velour
  • the second fabric being super-imposed with the pile adapted to obtain velours, carpet fabrics or moquettes or simply in a tubular manner whatever the length, with plain or intermediate connections which create continuous or intermittent channels or piping, with the incorporation of fibers, down, which may be expanded, glued, quilted or hooked, in layers or otherwise, or the fabric may also be completed by means of other additions.
  • the warp threads a may be used in lieu of the knitting threads b and vice versa, whereby the knitting threads b will function as warp threads.
  • This alternative embodiment may give to the final fabric some particular appearance or property, but it is necessary to make a judicious use of the combination possibilities so that, in any case, the bridging section of those-threads used as knitting threads can serve as a weft thread to be inserted in the shed left open by the thread used as warp threads.
  • fabrics may be obtained which range from the conventional woven fabrics to the conventional knitted fabric, with all the possible intermediate types as novel fabrics.
  • the deletion of the suppression of the weft inserting device enables the process of the present invention to manufacture fabrics over the whole width of the loom or in series of bands (or ribbons) to be woven side by side with a minimum of space lost in between the various pieces on either warp and/or Rachel looms.
  • the production of a fabric in accordance with the present invention may also encompass any additions deemed as required for the purpose of obtaining a desired result, but requires necessarily the combination, according to a defined weave, of:
  • one or several layers of b threads of which at least one is formed in loops and at least one provides the bridging sections that interconnect the wales and are to be inserted in the shed formed by the warp threads.
  • the same layer may be formed in loops and provides the bridging sections.
  • Warp a coming from a beam 1 and positioned by a thread guide roller 3 passes into the shafts 8 and 9 of a traditional harness, ensuring the formation of the shed and then goes into a reed 1 1 which distributes it, for example, in the pattern of one empty dent, and one dent having three or four threads.
  • Warp b coming from a beam 2 passes over a fixed roll 4, then over a balancer 6 pivotable about the axis which tensions the warp by means of a spring 7.
  • the warp b is then threaded into the rails of a plate 10 and finally passes into the empty dents of reed 11 with one thread per dent.
  • Plate 10 has a special movement which will be explained later.
  • the warp b guide plate 10 has an up and down movement which is calculated to ensure that the threads b are taken up on the needles 12.
  • the reed may have a to-and-fro movement such as that of the picks on weaving looms with a suitable amplitude, but it is also possible to give it a lateral movement in the manner of the guide bars in warp and/or Rachel looms.
  • FIG. 4 there is shown a knitting mechanism constituted by a needle bed 13 bearing the needles 12 and, a knock-over plate 14.
  • the caster and the needles (of whatever type) have a movement which is substantially parallel to that of the warp threads and which may be synchronized with the toand-fro movement of the reed.
  • the gauge of the needle bed is selected according to the article required.
  • the needle points When threads a cross each other and the reed is positioned such that the shed is open, the needle points will be opposite the dents of the reed supporting the b threads which fact presupposes that the gauge of the reed (i.e., the number of dents per unit length) is a multiple of that of the needle bed.
  • Needle bed and reed move towards the rear while the opening of the shed of threads a is taking place, the b threads being at the level of the lower layer and the needle field penetrating lightly into the shed above the lower layer of threads.
  • the earlier stitch opens up the needle latches.
  • the b threads are thus subjected to a lateral movement towards the right (or left) inducedby the reed, in order to face the next needle on the right (or left).
  • the plate 10 of the b threads then lifts up to engage the b threads on the right (or left) of the located needles and passes thereabove whilst a lateral return of the b threads, induced by the reed towards the left (or right) takes place at the same time as the plate 10 is again lowered as soon as the b threads have been engaged with the needles.
  • the b threads will then return to their initial position opposite the starting needles and at the level of the lower thread layer.
  • the combined movement of the reed and of plate 10 has put the b thread into the opening of the adjacent needle which continues to move backwards and lets the earlier stitch slide on its shaft and under the latch.
  • the stitcher assembly could also be provided with a lateral movement
  • the balancer system could be either modified or totally deleted
  • the harnessing system designed as a weaving scheme could be replaced by any other system which allows the required movement to be carried out, the arrangement of warp layers may be different:
  • the present invention relates to a new type of fabric characterized by a combination of new thread interlacings and by a manufacturing process for this new product comprising multiple possibilities of realization which are suitable to produce improvements whilst still remaining within the framework of the basic process.
  • a textile fabric constituted partly of a knitting component and partly of a weaving component, comprising in combination; first and second warp threads, said second warp threads being knitted together to form wales, and sections of said second warp threads interconnecting said wales being interwoven with said first warp threads whereby the knitting component of said fabric is interlaced with the weaving component of said fabric.
