Definitions

  • Conventional stitch bonded textile fabrics are well known in the art (see GB-A-2 166 460). They are produced by bonding together the fibers of a fleece by means of a plurality of columns of stitches. If envisioned in terms of conventional woven textiles with warp threads and weft threads, the plurality of stitch columns constitute the warp yarns and the bundle of fibers encompassed within an individual stitch and adjacent stitches in the weft direction constitute the weft yarns.
  • Another disadvantage is a low restistance to pilling, again attributable to the poor binding power between stitch loops and fibers in the weft-wise bundles. Individual fibers pull out of the bundle and pill on the surface of the fabric.
  • a further disadvantage is that the fabric has poor draping characteristics. This is the result of the relatively large length of the stitches which, in turn, create relatively large diameter weft-wise bundles of fibers. These coarse bundles are relatively stiff, thereby resisting drape folds parallel to the warp-wise stitches.
  • a machine also called a sewing-knitting machine, is e.g. described in the DE-OS 25 25 031. This machine is used to reinforce a web consisting of a non-woven fabric by sewing knitting threads into it. It is also known from the DE-PS 31 40 480 to lay parallel filler threads over a textile support layer and to reinforce this combined web by sewing knitting threads into it.
  • a warp knitting machine for stitching which employs offset needles in a stitch bond-type arrangement where the needles are offset in like fashion in repeat units and yarn guides for stitching yarns also offset in a like pattern.
  • the base fabric to be stitched is woven material.
  • the present invention provides a novel stitch bonded fabric and a machine and process for producing the same.
  • a conventional machine for producing stitch bonded fabric consists of a supply package of input fleece, feed belts that convey this fleece to an assembly induding fleece pins or web holders, sinkers, a reciprocating needle bar with a plurality of needles aligned along said bar in a single plane, corresponding yarn guides on the other side of the web to lay the stitching yarn in the needle hooks, and a take-up means for the finished fabric.
  • the just described elements are the main components of the stitch-bonding machine - numerous other ancillary components also exist in the machine.
  • the input fleece is selectively advanced past the needles as they repeatedly pierce the fleece.
  • Each needle - and its corresponding yarn guide - creates a stitch column in the fleece in a warp-wise direction. Since all of the needles are in a single plane, each column of stitches has loops that are in weft-wise alignment with corresponding loops in adjacent columns. The aligned loops in a given weft-wise row capture a bundle of fibers such that the bundle is straight across the fabric in a weft-wise direction.
  • the plurality of needles in the needle bar are not all in one plane, but instead are offset or staggered. Needles in the first, third, fifth, seventh, etc. position are in a first plane and needles in the second, fourth, sixth, eighth, etc. position are in a second plane.
  • the offset needles pierce the fleece and knit the warp-wise columns of stitches
  • the loops in adjacent columns are similarly offset from each other such that the weft-wise fiber bundles captured within the loops are distorted in an oscillated fashion - forming a pattern somewhat similar to two sinusoidal curves 180° out of phase with each other - rather than a straight bundle as is present in a conventional stitch-bonded fabric.
  • These twisted or distorted fiber bundles have a much improved binding power with the loops in the column of stitches, which greatly improves the weft-wise strength or stability of the fabric.
  • the improved binding power is attributable to the wrap angles of the weft-wise fiber bundles relative to the individual stitch-loops in the warp-wise columns.
  • a further advantage of an offset needle configuration is that a finer guage fabric can be produced.
  • conventional single plane needle configurations the dimensional relationships between needles, fleece pins, sinkers and yarn guides limit the machines to 28 guage.
  • two guide bars may be used to create a single bar construction with a fineness as high as 56 guage.
  • a single sinker and a single fleece pin can serve two needles offset from each other by configuring the sinker and the fleece pin as a crank, in a manner to be more fully described below.
  • This finer guage fabric is characterized by superior strength, drape and appearance. It also enables the use of shorter fibers in the fleece.
  • the invention is further based on the requirement to reduce the separating effect, which the penetrations have upon the web in terms of the above-mentioned tear-off perforation and the bunching effect, whilst maintaining a dense penetration pattern.
  • the web take-off is set in such a way that its length per knitting cycle is essentially equal to twice the distance of the penetration rows produced by both knitting needle rows. In this case consecutive zig-zag-shaped needle penetration patterns of equal distance are obtained, which imparts a uniform appearance and a correspondingly uniform reinforcement to the web.
  • the web may e.g. be a non-woven fabric. It is also possible to supply a web formed of diagonal filler threads. Moreover such filler threads may be combined with any given support layer, in particular to form a non-woven fabric.
  • a warp knitting machine for performing the above-described method is conveniently constructed in such a way that its two knitting needle rows are arranged on a common guide bar, in which case only one drive mechanism is required for operating both knitting needle rows.
  • a normal warp knitting machine may be used equipped with sharp-nosed knitting needles as normally used for sewing knitting threads into a web.
  • FIG. 1 is a schematic of the major components of a stitch bonding textile machine.
  • a roll 10 of fleece - such as produced by a cross folder - serves as an input supply of the fiber fleece which are to be bonded together to produce the fabric.
  • the input fleece can be fed directly from a cross-folder.
  • Feed belts 20A and 20B convey the fleece to the stitching zone 30, where it passes between fleece pins or web holder pins 50 and sinkers 40 in a conventional manner.
  • Needles 60 stitch through the fleece, creating a plurality of warp-like columns of stitches from yarn supplied from packages 80 through yarn guides 70.
  • Closing wire 90 functions in a conventional manner to close the hook on needle 60.
  • Additional guide rolls 20C convey the stitch bonded fabric to take-up package 100.
  • Needle bar 64A holds a plurality of needles 60 (only the closest of which is visible in the figure), each of which has a point 61, a hook 62 and a groove 63 to accommodate closing wire 90.
  • a web path W exists between knocking-over sinkers 40 and web holder pins 50, both of which are attached to the machine by means of sinker leads 41 and web holder pin leads 51, respectively.
  • the point 61 of needle 60 passes through the web, picks up a stitching yarn in hook 62 from yarn guide 70, and pulls the yarn through the web to form, in cooperation with sinker 40, a stitch.
  • there are a plurality of needles 60 In a conventional stitch bonding textile machine, there are a plurality of needles 60, all located in the same plane. In like manner, there are a corresponding plurality of sinkers and fleece pins.
  • needle bar 64B of the present invention is shown in an oblique view in Figure 3.
  • Needles 60 are staggered or offset from each other both vertically and horizontally such that they fall into two planes A-A and B-B and such that a needle in plane A lies over the space between two needles in plane B.
  • the horizontal spacing between needles may be varied, as may be the vertical spacing.
  • the offset needles illustrated in Fig. 4 show less of a vertical spacing than the needles in Fig. 3.
  • the embodiment of Fig. 4 has the front needle obscuring a portion of the needle behind it, and so on for all the needles in the bar. While this preferred embodiment is described with respect to offset needles in only two planes, it should be understood that offset needles in more than two planes are also contemplated for some applications.
  • Figure 4 illustrates the stitching zone in a view similar to Figure 2, but in which needle bar 64B of the present invention and its offset needles replace the conventional single plane needle bar 64A of Figure 2.
  • needle 66 is in plane A-A and needle 65 is in plane B-B, although these planes are vertically doser to each other than those shown in Fig 3.
  • a plurality of needles exists in each plane - only one in each plane is shown in Figure 4.
  • a conventional stitch bonded fabric is illustrated in Figure 5.
  • a plurality of stitch columns C 1 , C 2 , C 3 , C 4 , C 5 ...C 12 are formed in the warp-wise direction, and a plurality of fiber bundles B 1 , B 2 , B 3 , B 4 , B 5 ...B 12 are formed in the weft-wise direction.
  • the columns of stitches C constitute the warp yarns and the fiber bundles B constitute the weft yarns.
  • the vast majority of the fibers in the fleece are captured by the individual stitches and form part of a given bundle but, as is apparent in Figure 5, a small number of fibers f lie outside the bundles.
  • the fiber bundles When the fabric of Figure 5 is subjected to a weft-wise tension, the fiber bundles have a poor binding power with their corresponding stitches, and slip through same with relative ease. This results in a fabric with a poor, or low, weft stability.
  • a fabric produced according to the present invention is shown in Figure 6.
  • the columns of stitches are indicated by reference letters C' 1 , C' 2 , C' 3 , C' 4 ... C' 12 with columns C' 1 , C' 3 , C' 5 ... knit by needles in one plane and columns C' 2 , C' 4 , C' 6 ... knit by needles in a second plane.
  • Fiber bundles B' 1 , B' 2 , B' 3 ...B' 12 form a oscillating pattern quite different from the pattern formed by the bundles in Figure 5.
  • Figure 6A is a greatly magnified view of the upper left corner of the fabric structure shown in Figure 6.
  • Three stitch columns C' 1 , C' 2 , C' 3 and three fiber bundles B' 1 , B' 2 , B' 3 are shown in Figure 6A.
  • the oscillating path assumed by each bundle is readily apparent from Figure 6A.
  • Bundle B' 1 is completely encompassed in stitch S 1a of column C' 1 but then, moving to the right of the figure (in a weft-wise direction), splits so that roughly half of bundle B' 1 is encompassed in stitch S 2a of column C' 2 and the other half is encompassed in stitch S 2b of column C' 2 .
  • bundle B' 1 comes together and is completely encompassed within stitch S 3a in column C' 3 .
  • the bundle configuration just described occurs with the majority of the fibers in a given bundle. In actual application, there exists some minor but unpredictable fiber cross-over from bundle to bundle, such as shown by filament f' passing from bundle B' 2 to B' 1 and beyond.
  • This oscillating pattern repeats itself throughout the fabric and creates a more efficient binding power attributable to greater frictional engagement between bundle and stitch created by the wrap angle of the bundle around the stitch yarn. This creates a greatly. improved weft-wise tensile strength and resistance to distortion, or a high weft stability. This fabric structure also results in good pilling resistance and improved drape characteristics across the filling.
  • Comparative tensile strength tests were run on a sample of conventional stitch bonded fabric and a sample of fabric produced according to the present invention.
  • the distance between stitches in a given column was 1.4 mm.
  • the needle planes A-A and B-B were offset 0.7 mm and the distance between stitches in a given columns was held to 1.4 mm.
  • the stitches in adjacent columns were offset from each other by half their length.
  • the guage of the two samples was the same, i.e., 28 gauge.
  • the fleece consisted of 4 denier - four inch length polyester.
  • the weight of one sample of the conventional fabric was 4.67 ounces per square yard while the fabric of the invention weighed 4.40 ounces per square yard.
  • Tensile-Warp Direction - 1bs A tensile force measured in pounds was applied in the warp direction until failure.
  • Tensile - Weft Direction (Filling) - 1bs A tensile force measured in pounds was applied in the weft direction until failure.
  • Initial Modulus Filling - gms. An indication of force per unit stress, i.e., stress in grams divided by strain - i.e. % stretch.
  • Stress in grams i.e., stress in grams divided by strain - i.e. % stretch.
  • Sample 1 of the conventional fabric indicates that for 252 grams of force applied, the sample stretched 1%. This is an indication of the resistance to distortion.
  • Modulus Filling - grams i.e., the additional grams of force required to take the sample from its initial modulus to failure. This is an indication of the resistance to failure after the fabric has been distorted.
  • the samples were also subjected to a standard ASTM Random Tumble Pilling Test, and compared with samples - in a visual grading scale of 1-5, with 5 being excellent.
  • the conventional fabric was 3.0 - i.e. moderate pilling.
  • the fabric of the invention was 4.5 - very slight pilling.
  • Figure 8 is a schematic view of the components in the stitching zone when modified to produce a fine guage fabric. Like elements are numbered as in Fig. 4, but with prime (') designations.
  • the plane of needles which includes needle 66' is vertically offset from the plane of needles which includes needle 65' by an amount greater than that shown in either Fig. 4 or Fig. 3.
  • the vertical offset may be, for example, four and one-half stitch lengths -i.e., 6.35-mm which is sufficient to accommodate yarn guide blades that are 2 mm wide.
  • the sinker blades 40' must be made longer so that the offset needles can fit between sinker leads 41' and sinker nose 42'; (2) the fleece pins 50' must also be made correspondingly longer; (3) closing wires 90' 1 and 90' 2 must be offset in two planes corresponding to the needle offset such that they can ride in the corresponding grooves in the needles; and (4) the needles in the upper plane (as seen in Fig. 8) are cranked at location D so that needles in both planes can be cast into a conventional sized needle bar 64B'. Alternatively, if needle bar 64B is made larger in the vertical dimension, the upper needles need not be cranked.
  • the clearance between the yarn guide blade and needle - both in front and behind the hook - should preferably be a minimum of 1 mm.
  • the opening of the sinker window X (see Fig. 9) will be large enough to accommodate both needles - in this example, the window would be 8.85 mm.
  • Both the sinker blades and the fleece pins are bent into a crank-like configuration, as is visible in Figs. 9 & 10.
  • This cranked configuration permits a single sinker blade, and a single fleece pin, to serve two needles, one in each plane.
  • Sinker pins 40' should preferably have a hole 43' punched in each with a supporting wire 44' running therethrough to support the back side of the needles 66'. (The lower needles 65' are supported by sinker nose 42'.)
  • crank offset of both sinker blades and fleece pins is determined by dividing the guage - i.e., the number of needles per inch into 25.4 mm - the number of millimeters in one inch. Thus for a 56 guage needle assembly, the crank offset is 0.454 mm, indicated by Y in Figs. 9 and 10.
  • the finer guage fabric would have vastly superior strength, drape and appearance, and would enable the use of a shorter staple length fiber in the fleece.
  • Figure 11 shows a section of a web 101 formed of diagonal filler theads 104, which has been treated by the method according to the invention and which was subjected to two knitting cycles during which two needle penetration rows respectively were produced simultaneously, i.e. rows 102a and 102b and 103a and 103b.
  • rows 102a and 102b Within the two rows 102a and 102b a zig-zag-shaped penetration pattern exists of which the penetrations of row 102b are symmetrically offset in relation to the penetrations of row 102a. Rows 102a and 102b are simultaneously worked in one knitting cycle.
  • the take-off length of the web per knitting cycle is such that the distance with which penetration row 103a follows penetration row 102b is twice the distance between penetration rows 102a and 102b. In this way the same penetration pattern repeats, at a distance such that the individual penetration patterns repeat symmetrically following each other resulting in an altogether uniform appearance of all penetration patterns. As a consequence a correspondingly evenly distributed reinforced web 101 is obtained on the basis of the needle penetrations and the worked-in knitting threads. But it is also possible, of course, to operate the respective machine at a shorter or longer web take-off per knitting cycle.
  • the needle penetrations of row 102b as projected lie resp. centrally between two penetrations of row 102a in feed direction of web 101 (indicated by the arrow) so that when projected this way, a uniform relatively narrow pitch is obtained. But since this narrow pitch does not belong to a row of adjacent needle penetrations, the penetrations of one knitting cycle resp. being spaced and offset at a distance from each other, sufficient distance remains between individual penetrations of rows 102a and 102b to ensure that undesirable bunching of the fibres of web 101 or diagonal filler threads 104 is avoided, although in total a considerable density of individual needle penetrations is obtained across web 101.
  • the adjacent penetration rows shown in figure 11, i.e. 102a and 102b and 103a and 103b are, as already mentioned, produced simultaneously in a single knitting cycle, with 2 rows of sharp-nosed knitting needles penetrating the web 101 submitted at any one time.
  • the knitting tools of the warp knitting machine used in this case are illustrated in figure 12, the base fabric being a web in the form of a non-woven fabric 107.
  • These knitting tools consist of sharp-nosed slide needles 108 and 109, whereby these two needles belong to one row of slide needles resp. extending longitudinally to the needle array.
  • the two needle rows containing slide needles 108 and 109 therefore penetrate (the web) they produce the penetration rows 102a and 102b seen e.g. in figure 11.
  • the two needle rows containing slide needles 108 and 109 are both attached to sliding guide bar 120, i.e. they are operated jointly as the guide bar 120 is moved up and down in the customary way.
  • Assigned to slide needles 108 and 109 are the slides 111 and 112, which are also operated by a common sliding guide bar 113. Cooperation between needles 108 and 109 and slides 111 and 112 is as commonly known for slide needles.
  • Laying of the warp threads serving as knitting threads is effected by two laying guides 124, 125 for each two slide needles 108, 109, the laying guides being suspended in the known manner from laying guide bars 116, 117 and operated by the same.
  • One laying guide would already suffice for each two knitting needles 108 and 109.
  • more than one laying guide may be conveniently provided.
  • the web submitted in the form of non-woven fabric 107 is supplied via the knock-over sinker 118 and held from above in a downward direction by the trace comb 106.
  • two penetration rows (e.g. 102a and 102b in figure 11 are produced by the two needle rows containing knitting needle 108 and 109, which two penetration rows are repeated with each subsequent knitting cyde.
  • the web take-off speed set appropriately, consecutive zig-zag-shaped needle penetration patterns of equal distance are obtained resulting in the altogether uniform appearance seen in figure 11.
  • This figure also reveals that the warp knitting machine of figure 12 is able to operate at twice the take-off speed compared to other machines with only one row of knitting needles and thus with twice the output since one knitting cycle on this machine corresponds to two knitting cycles of a machine with only one row of knitting needles.
  • the two laying guides 114 and 115 are required, which are assigned respectively to the two knitting needles 108 and 109 for laying the warp threads around the respective knitting needles.
