FOR USE AS WAISTBAND REINFORCEMENT
Abstract of the Disclosure An elastic warp knit fabric having a rela-tively stiff monofilament inlaid in the fabric be-tween the courses thereof in a sinusoidal fashion so that the reverse portions of the monofilament did not extend to the outer extremities of the fabric.
In one form of the invention a skirt is provided on one side of the fabric to decrease the possibility of cutting the monofilament when being connected for use as a waistband for body conforming garment.
Description
The present invention is directed to an elastic warp knit fabric con~truct:ion and its meth-od of manufacture, and, more particularly, to an elastic warp knit narrow tape or band fabric partic-ularly suitable for use as a waistband support in garments.
It is known to employ narrow elastic fabric bands or tapes having long:itudinal stretchability and good transverse sta~ ity in the waist portion of garments, such as skirts, slacks, and pants, to provide po~itional support of the garments on the wearer. In such garments, it is desirable that the elastic band or tape have a high degree of stretch and elastic recovery in the lo~gitudinal direction ,s.

; to fit waists of varying size and to provide sup-port of the garment on the wearer. It is also desirable that such bands be of sufficient width to be comfortable to the wearer and to have widthwise stability against rolling, twisting or bending of the tape in the garment during wear.
Such elastic fabric bands typically consist of a narrow knitted or woven tape containing elas-tic yarns, such as spandex or rubber, disposed in the longitudinal or warp direction and relatively large and stiff monofilament synthetic yarns such as nylon, employed in the transverse or weft (fill) direction to resist the tendency of the tape to roll or twist on the wearer's waist during use.
Although such tapes can be produced individually on narrow looms or needle looms, it is desirable for economy of production, particularly in handling and finishing, to manufacture the tapes from wide or full width fabrics from which can be suitably cut after finishing into individual narrow widths.
~t is recogni~ed that in waistband support tapes employing relatively large, stiff weft yarns that there is a tendency for the sharp ends of the ; weft yarns at the outer side edges of the tape to stick the wearer and be uncomfortable during use.
When such tapes are made by cutting a wide woven or knit ~abric lnto narrow strips~ the sharp cut ends of the yarns are often subsequently coated with a suitable polymeric resin to provide a pro-3Q tective bead or covering on the cut edges of the `:;
fill yarns and reduce their roughness during wear.
Typical of Ruch textile fabrics and their produc-tion are described in U. S. 3,597,300. It can be appreciated that the additional. coating of the edges of the fabric bands to protect the wearer from the rough edges of the stiff wet yarns requires addi-tional processing ~teps in the manufacturing opera-tion. Even if the tapes are made individually on narrow looms or ~mall needle looms, the stiff fill yarns extending to the outer edges of the ape can produce discomfort for the wearer.
It i8 an object of the present inventi~n to provide a narrow ~idth elastic fabric band or tape construction particularly suited for u~e as an elastic waist support in garments which overcomes to a large extent certain of the problems experi-enced in the prior art.
The invention in one aspect provides a warp knit fabric of relatively wide width comprising a plurality of relatively narrow knit tape constructions positioned in ~ide-by-side relation across ~he width of the fabric and joined at their side edges by a removable yarn, each narrow tape cons~ruction ~omprising a plurality of pairs of relatively inelastic yarns with each yarn forming single stitches in every course and wale of the tape, a plurality of relative.ly elastic yarns inlaid in said stitches and with elastic yarn extending across at least one wale of the tape from course to course, and a relatively E~tiff and heavy monofilament yarn in-laid in the stitches and extending across the tape ~ _ 3 _ - - .. : : .
between every course, said monofilament yarn at ~11 times being positioned inwardly of said edges of the tape construction whereby said monofilament yarns are effectively covered by the yarns adjacent the edges of the tape.
More particularly, a typical embodiment of the present invention is directed to ~he production of an elastic warp knit fabric band construction hav-.- ing the desired stretch and elastic recovery in the longitudinal direction and employing rigid mono-filament yarns in the wid~hwise direction for stability against roll, and wherein the ~tiff mono-filament yarns are effectively maintained within, - or inside, the side edges of the band to greatly reduce discomfort to the wearer. The invention al-so provides a method of producing such warp knit elastic bands in an economical manner by knitting a wide width fabric construction from which the bands can be easily s.epar~ted into individual tapes.

73g The warp knit elastic fabric construction of the present invention comprises a plurality of sets of relatively inelastic yarn forming a knitted ground construction, sets of elastic yarns inlaid therein to provide longitudinal stretch, and a set of stiff monofilament yarns to provide good trans-verse dimensional stability against bending or roll-ing of the tapes during their use. Additionally, the construction may contain a plurality of covering yarns, such as textured yarns, to effectively hide the elastic yarns in the tape construction.
The narrow elastic fabric bands o~ the pre-sent invention are preferably produced by knitting a wide width fabric construction which can be econ-omically finished in wide width form, and whlch thereafter can be easily separated into the multiple fabric bands withQut cutting. The elastic band construction also maintains the relatively sti$f monofilament yarns inside the side edges of the band so as to eliminate the necessity of a sub-sequent edgecoating operation to prevent discomfort to the wearer during use and to prevent acciden-tal severing of the fabric during the garment forming operation.

Looking now to Figure 1, the fabric 10 is shown schematically as it comes off the knitting machine with individual widths 12 of the fabric being connected together on the knitting machine by a connecting yarn 14 in order to knit a plurality of waistband tapes 12 at the same time. In the pre-ferred form of the invention, each of the tapas 12 are approximately one inch (1") in width and have a skirt portion 15, ha~ing a width of approximately one-eighth inch (1~8"), at one side thereof for reasons hereinafter explained.
The fabric construction shown in Figures 2-11 is preferably knit on a Raschel warp knitting ma-chine having at least nine guide bars to form the desired characteristics in the fabric. As discussed above, a wide width of fabric is knit with each tape 12 encompassing eighteen needles in the course di-rection with the overall design repeating every eight courses.

Tricot stitches 18 of 150 denier polyester yarns are used for the selvedges of the tapes 12 to prevent unraveling thereof while lock stitches 20 and 22 oE 150 denier polyester yarn form a divided warp to provide strength to the fabric, prevent un-raveling in the warp or wale direction and cover )7~
for the spandex yarn 24 laid in by the movement of bar 8. The stitches 20 and 22, respectively are controlled by the movement of bars 3 and ~.
Bars 5 and 9 lay in yarns 26 and 28 of 150 denier textured polyester yarn between adjacent courses of the fabric 12 to provide top and bottom cover for the 800 denier polyester monofilament yarn 30, also laid in be~ween adjacent courses of the fabric to provide rig:idity in the fill or course direction of the fabric while the spandex yarn 24 ¦ provides elasticity in the warp or wale direction of the fabric. Figures 7 and 11, respectively show the lay in of the cover yarns 26 and 28 while ~igure 9 shows the lay in of the polyester monofilament yarn by bar 7.
To provide a connecting stitch, bar 6 guides in the yarn 32 of 70 denier polyester on both sides of the fabric 12 for interconnection with the chain stitch 16 which connects adjacent tapes or bands 12 together in the warp or wale dire~tion to form the fabric 10.
As dis.cussed brie~ly before the monofilament 30 is laid in between adjacent courses to provide rigidity in the course direction and follows a sinusoidal path throughout the length of the fabric.
The rigidity of the monofilament prevents the tape 12 from bending when used as a waistband in a gar-ment since it will be parallel to the standing position of a person wearing such garment. At the . , , .. ~
~1~2V73~
same time, the us~ of such a monofilament, if acci-dentally severed while heing placed in a garment, will cause discomfort to the wearer of the garment.
This accidental severing of the monofilament usually occurs where the monofilament reverses direction in the ~abric ad~acent one end thereof on the side of the fabric which is sewn to the garment and cut.
To greatly decrease this possibility, this side of fabric 12, which is the righthand side on Figures 1-11, the monofilament is reversed at a point which is at a greater distance inward from the edge of the fabric than the reversal point of the mono-filament at the other side of the fabric. This difference in distance is preferably equal to the spacing between two adjacent needles. To provide the skirt 15 on this side of the fabric, an addi-tional selvedge yarn 18 is guided therein by bar 2 so that the reversal point of the monofilament is inwardly substantially from the edge of the tape 12.
As disclosed in the preferred embodiment, the tape is basically being knit using three bars, namely bars 2, 3 and 4 with bars 4-9 laying in yarn but, obviously, if desired, the tape can be knit us~ng four bars, namely bars 1-4, with bars 4-~

It can readily be seen that a waistband fabric has been provided which can be manufactured in wide widths which can be readily separated to provide in-dividual waistband fabrics that has rigidity in the course direction and elasticity in the wale direction.
