WARP KNITTED SELF-LINED FABRICS
WITH WOVEN APPEARANCE
ABSTRACT
A self-lining decorative fabric is especially adapted for use as a drapery, and simulates the appearance of a woven fabric. The fabric includes a non-woven or other substrate fabric with weft yarns disposed on a first face of the substrate and warp yarns disposed on the first face of the substrate laying on top of the weft yarn. The warp yarns extend in lines substantially perpendicular to the weft yarns, although they may have curvilinear or zig-zag paths while extending in such lines. Stitching thread holds the warp and weft yarns in place on the substrate first face, stitch portions of the stitching thread passing over the warp and weft yarn, and loops of the stitching thread being disposed in contact with the substrate second face, opposite the first face. The stitching thread may be the same color as the substrate while the majority of the warp and weft yarns are of a different color, and at least some of the warp and weft yarns preferably are effect yarns. When used as a drapery material, a foam backing or other coating may be applied adhering to the substrate second face.

In the production of decorative fabrics, particularly fabrics for home furnishings, such as drapery casements, it is desired to provide self-lining in order to increase fabric opacity and to simulate the appearan~e of a separate lining. Also to allow the application of a foam backing to a type of fabric which otherwise could not be successfully foam backed utilizing conventional techniques.
Further, it is desirable to produce such a self-lined fabric at minimun cost consistent with providing a desirable appearance, a simulation of a woven fabric on the face - with or without effect yarn~.
According to the present invention, a self-lining decorative fabric is provided that has all of the advantages associated with self-lined fabrics, and can be produced in a simple and cost-eEf~ctive manner while ultimately providing a ver~ aeqthetic appearance. The ~abric according to the present invention simulates a woven fabric in appearance and dimensional stability, provides increased fabric opacity without stif~ening "handn, and allows appli-cation of a foam backing utili~ing conventionaL
techniques. The fabric according to the invention is ideally suited for use as a drapery fabric because o~ aesthetics, cost and dimensional stability. It has enough versatility of design to be utilized for a wide variety of decorative purposes, particularly in the home furni~hings area.

The dimensional stability of the compound fabric constructions make this type of manufacture important for industrial fabrics. Similarly, an economic fabric construction achieving opacity through a substrate and controlling the tensile strength with minimum warp and filling threads make attractive for use as print fabric such as for ticking.
According to one aspect of the present lo invention, a self-lining decorative fabric is provided simulating the appearance of a woven fabric. The fabric includes a substrate fabric weave having first and second faces with wef~ yarns disposed on the first face of the substrate, and extending parallel to each other. Warp yarns are disposed on the first face of the substrate and extend in lines substantially parallel to each other and perpendlcular to the we~t yarns, the warp yarns laying on top of the weft yarns at all points of intersectian. Stitching thread holds the warp and weft yarns in place on the substrate first face, the ~titching thread including stitch portion~ and loops with the stitch portions operatively engaging the warp and weft yarns on the substrate first ~ace, and the loops ~eing disposed in contact with the substrate second face.
The fabric according to the present invention may be produced on a commercially available machina manufactured by Rarl Mayer Machinery Co. of the Federal Republic of Germany.
~he machine is a warp knitting machine having pointed (piercing) stitching needles, a substrate fabric feed, a weft-in~ertion feed that feeds the weft yarns truly perpendicular to the warp yarns, and means for introducing decorative warp yarns, .

Feeding warp yarns, extending in lines parallel to each other and perpendicular to the weft yarns, to the stitching needle substantially in the first direction, the warp yarns being laid on top of the weft yarns at the stitching needles. And, stitching through the substrate with the stitching needles to loop stitching threads stitch portions over warp and weft yarn3 to hold them ln place on the substrate first ace, and to form stitch loops on the substrate second face.
By providing the warp yarn~ extending in lines perpendicular to the weft yarns a woven appearance is simulated and the stability of the fabric con~truction improved. A wide variety of decorative effects may be obtained by using effect yarns for the warp and/or weft yarns, and by providing at least some of the warp yarns in curvilineae or zig-zag paths while extending in their lines perpendicular to the weft yarns. The stitching threads s~itch portions each pass over and hold the warp and weft yarns, with the warp and weft yarn~ passing between a stitch portion and the substrate first face. The stitching thread stitch portions may be provided in a zig-~ag configuration, straight line configuration, or the like. For some purposes, the stitching threads may be provided as ~17~
the same color as the substrate (e.gl, white) while the majority of the warp and weft yarns are of a different color than the substrate, simulating a woven appearance.
When used as an open type self-lining drapery casement fabric, it may be des;rable to provide a foam backing to the substrate second face, the foam encapsulating the stitching thread loops~
Foam backing may be practiced as taught by U.~.

While a non-woven is desirable as the substrate fabric for most purposes, if desired for a parti-cular situation a woven or knit substrate film or foil may be provided.
The substrates mentioned above could be selected to increase the decorative effect, e.g., by causing pucker of the face fabric through differential shrinkage. Also the substrates could be used for functional qualities such as heat dissipation o~ lighted cigarette for ticking or upholstery fabrics, insulation of heat transmission or heat refle~tion for drapery or appar~l abrics, or sound insulation for drapery fabrics.
Construction of fabrics for the desired performance could require one or several substrates inserted in a sandwich.

DETAILED DESCRIPTION OF THE DR~WI~GS
An exemplary fabric according to the pre~ent invention is indicated generally by reference numerals 10, 10', and 10~ in FIG~RES 1-3, FIGUR~ 4, and FIGURE S, respectively. The fabric 10, 10', and 10~ comprises a self-lined decorative fabric which~ as an inspection of FIGURES 1 and 5 in par~icular makes clear, simulate~ the appearance of a woven fabric, and is eminently suitable for use as a drapery casement fabric. The fabric 10, 10', and ,' ` ~
~ 1 ~78 1 ~
10" is desirably produced on a commercially available warp knitting machine pr~duced by Rarl Mayer Machinery Co. of the Federal Republic of Germany, Model No. RS4(6)MSU, such a machine having a substrate fabric feed, parallel weft insertion, pointed Qtitch through needles, and decorative warp yarn introducing means.
As FIGURES 2-4 make clear, the fabric 10, 10', and 10~ according to the present invention include~ a substrate 12 having a first face 13 (see FIGURE 2) and a second face 14, opposite the first face 13. Depending upon the ultimate use of the fabric 10 and substrate availabilities, the substrate 12 may be a non-woven, woven, or knit fabric film or foil. A light non-woven fabric such a~ that produced according to U.S. Patent 3,485,706, is preferred for most 31tuations, especially when the ~abric 10 comprises drapery casement fabric.
Weft yarns 16 are di~posed on tha first face 13 oE the substrate 12, the weft yarns 16 extending parallel to each othe-r. If desired, the we~t yarns may be efect yarn~,, the term "effect"
being a generic term to describe all types of yarns having pronounced variations ~n linear density, such as knops, loops, slubs, lumps, nubs, and the like.
For instance, weft yarns 16', lSW illustrated in FIGURE ~ are a slub yarn (having an irreqular, fuzzy configuration over the entire length ~hereof) and a nub yarn (having irregular configurations at spaced pointQ therealong) respectively.
The weft yarns can be introduced singly or with two or more yarns placed in the same course simultaneously. This could be for a decorative effect, economy, or to increase the tensile strength ~17~
with a yarn combination, e.g., fine filament with a coarse weak spun yarn.
The fabric 10 ~10', lOn~ further comprises warp yarns 18 disposed on the first face 13 of the substrate 12 and extending in lines L (see FIGURE 2) substantially parallel to each other and perpendicu-lar to the weft yarn 16, and laying on top of the weft yarns 16 at all points of intersection. While the warp yarns 18 extend in lines L perpendicular to ~0 the weft yarn 16, they may extend in curvilinear or zig-zag paths, as clearly illustrated in FIGURES 1,
2, and 5. At least some of the warp yarns 18 also preferably are effect yarns.
The fabric 10 (10', lOn) also includes stitching thread holding the warp and weft yarns 18, 16 in place on the substrate first face 13. The stitching thread is indicated generally by reference numeral 20, and includes stitch portions 2~' and loops 20n. The stitch portions 20' each pass over and hold the warp and weft yarns 18, 16, with the warp and weft yarn 18, 16 passing between a stitch portion 20' and the substrate first face 13.
Preferably each stitch portion ;20' holds a weft yarn 16 ~although ~kipped picks may be provlded), and at 2s least some o~ the stitch portiolls 20' hold a warp yarn 18. In the embodiments illustrated in FIGURES
1, 2, and 5, warp yarns 18 are provided only at predetermined intervals along the fabric face, there being no provision ~or one warp yarn for each row of stitching thread 20. The loops 20' are disposed in contact with the substrate second face 14, conventional chain stitching being illustrated in FIGUR~S 2 and 3. Variations in the exact stitch configuration o~ the stitching thread 20 may be provided. For instance, the stitching thread 1~781B~
portions 20' may be provided in a straight line configuration as illustrated in FIGURES 1 and 2, or they may have a zig-zag configuration as illustrated in FIGUR~ 5. Alternatively, tricot stitche~ may be provided, or any other type of conventional stitching achievable utilizing a warp knitting machine.
In order to obtain proper aesthetic effect, the stitching thread 20 may be provided having the same color as the substrate 12 (e.g., white), while the ma~ority of the warp and weft yarns 18, 16 are of colors different than ~he substrate 12a Especially where a white substrate 12 and white stitching thread 20 is provided with multi-color warp and weft yarns, an appearance truly simulating that of a woven fabric is provided at a distance of more than a few inches.
FIGURE 4 illustrates a fabric 10' according ~o the present invention which Ls identical to the fabric 10 only it includes a foam backing 25~ An open-weave fabric normally cannot be successfully foam-backed utilizing conventional techniques, however, the sel~-lined fabric according to the present invention may be successfully foam backed.
The foam backing 25 is applied to the substrate second face 14, and encapsulates the stitching loops 20'. After production of the fabric 10, it is fed to a conventional foam backing station, and conventional foam-backing techniques are utilized to apply the backing 25. Two conventional types of foam backing techniques are disclosed in U.S.
Patent~ 3,527,654 and 4,072,775.
As previously indicated, a decorative fabric 10, lOi, and 10~ according to the present invention is produced on a commercially available .

warp knitting machine having pointed stitching needles. The substrate 12 is fed in a first direction to the stitching needles of the warp knitting machine, while parallel weft yarns 16 are fed in the first direction, with yarn 16 being disposed in a second direction perpendicular to the first direction. The weft yarns 16 are in contact with the substrate first face 13 at the stitching needles. Warp yarns 18 are fed, extending in lines parallel to each other and perpendicular to the weft yarns, to the ~titching needles substantially in the first direction, the warp yarns being laid on top of the weft yarns 16 at the stitching needles. The fabric is completed by stitching through the substrate 12 with the stitching needles to loop stitching threads stitch portions 20' over the warp and weft yarns 18, 16 to hold them in place on the substrate first face 16, and forming ~titch loops 20~ on ~he substrate second face 14. The decorative warp yarns may be introduced by patterning bars, or with a straight lay-in bar plu9 patterning bars, and under some circumstances no decorative warp yarns need be provided, but rather thle stitching threads themselves can provide the woven e~fect (in conjunction with the weft yarns). If foam backing of the fabric were desired, after formation it would be passed to a foam backing station and the backing 25 applied to the second face 14 of substrate 12.
It will thus be seen that according to the present invention an aesthetic, functional fabric has been provided which has a wide variety of uses, but is particularly adapted for use as a drapery casement.
