BACKGROUND OF THE INVENTION
This invention relates to self-lined composite fabrics ~.
of novel functional and aesthetic design. More particularly, it
relates to a novel self-lined fabric which is produced on stitch-
through type machines such as a.Malimo machine and to an apparatus
and method used in making it wherein the fabric is self-lined by ~ `
; one of its own components and which is useful amon~ other things ~ `
in decorative applications such as draperies where it is desired
~ to provide such fabrics with a lining or backing which forms an
integral part of the overall fabric structure.
Malimo fabrics typically comprise a layer of substan~
tially parallel warp yarn elements or ends on a flexible sub-
strate such as a layer of substantially parallel textile filling
~: elements or ends. The warp yarn elements are affixed to the
flexible substrate by laying one on top of the other and joining
.` them into an integrated structure by means of relatively fine
kni.tting threads. In the case where the flexible substrate is
a layer of textile filling elements, a more or less open mesh
~` fabric can be obtained by controlling the spacing between the
individual warp yarn elements and~or the individual filling : ~:
elements. m is and other "stitch-through" type fabric structures
can be obtained on machines of the "Malimo" type, using methods
and equipment described in UOS. 2,890~579; U.S. 3,030,786;
U.S. ReO 25,749; U~So 3,253,426; U.S. 3,274,806; U.S. 3,279,22Z;
UoS~ 3,309,900; U.S. 3,389,583; UoSo 3,392,078; U~So 3,440,8~0;
U.S. 3,452,56Z; UoS~ 3,457,738; UoS~ 3,460,599; U.S. 3,540,238;
U.S~ 3,54Z,8Z2; U~So 3,567,565; and UOSO 3,592,025.
The ability to readily mass-produce a basic fabric in
a variety of patterns is extremel~ important to the comN~ercial
- 2 -
7~38
success of the fabric. ~hile fabric can be produced on the "Malimo"
machines at a very high rate of spee~, much attention has been given
to augmenting this desirable feature with design flexibility, e.g.,
with respect to the density, gauge, and color combination of the
fabric components, the spacing between them, and the purposeful
omission of one or more of such com onents.
Hcwever, a need has existed for Malimo fabrics of still
further design flexibility, not only with respect to the creation
of unusual visual effects but also with respect to achieving new
and useful functional features by incorporating additional com-
ponents into the fabric. For example, extensive use has been
sought in the decorative fabric industry for thin sheets of elasto-
meric foam, made from either natural rubber or synthetic polymeric
materials. In one type of structure, the fabric layers are normally
attached to the foam by spaced-apart quilting stitches.
Considerable interest has also been shcwn in bonded
fabrics, where a layer of a conventional fe~bric is bonded to a
thin sheet of elastomeric foam by means of an adhesive to form a
composite fabric having the limited extensibility and hard ex-
terior surface of the conventional fabric and the insulatingproperties of the foam layer.
While quilted or bonded laminates of fabric and elasto-
meric foam are useful for some purposes, such conventional com-
posite fabric construction suffer certain serious drawbacks which
limit the number of applications in which they can be used. In the
case of bonded laminates, the interposition of an adhesive between
the foam and fabric layers creates problems both in processing and
in the end use of the fabric. For example, extreme care must be
observed in the selection of a suitable adhesive, and in the
application thereof to the foam -to insure proper bonding
~7~
in order that the flexibility and insulating properties of the foam
are retained. Also, the extensibilit..y of a laminate of this type is
limited by the stretch properties of the fabric portion of the lami-
nate and by the nature of the adhesive used.
Another drawback in the manufacture and use of conventional
laminates of fabric and elastomeric foam is manifested in the fact
that the elasto~.eric foams presently available are somewhat fragile
and difficult to handle in the thicknesses ordinarily used for fab-
ric purposes. It is recognized that polyurethane foams tear rather
easily and lack adequate resistance to the effects of heat, oxida-
tion and sunlight, which ultimately contribute to the disintegration
; of such backing materials. Also, whether the foam is bonded to a
conventional fabric by adhesive, or loosely joined therewith, as
by the use of quilting stitches, the resul.ting fabric hcas a hand
which is more characteristic of the foam than of the fabric joined
with it, thereby effectively precluding t~le use of such composite
"fabrics" in applications where the hand m~lst be predominantly that
of the ~abric component.
It is in the decorative drapery or casement fabric field
that the shor~comings of prior techniques for combining functional
backing materials with ornamental textile fabric structures are
particularly significant. This situation has become more notice-
able in recent years during which the demand for decorative
drapery fabrics possessing thermal insulating properties has in-
creased markedly in the face of rising home and office heating
expenses and energy costs.
l~hile the use of alternative methods for producing
textile fabric structures containing a layer of functional
sheeting material (e.g.l elastomeric foam) inter~osed between
layers of textile ele~.ents has been disclosed in the art, e.g.,
,. . ~. ~
748~
in U.S. 3,274,805 and U.S. 3,27~,806 the search for other novel
types of fabric constructions which differ from those heretofore
developed still continues. The present invention provides a lined
decorative fabric suitable for making on a stitch-through type
of machine, such as a Malimo machine, which overcomes the short-
comings of the prior art construction described above. The
invention further provides practical as well as aesthetically
useful composite fabrics in which a component lining material
~ performs a definite function (e.g., thermal insulation) either
~er se or through special post-treatment (e.g., resin back-
coating which also provides a convenient way of achieving a
"blackout" effect when desired) without interfering with the
decorative function of the remaining components of the ~abric
which are positioned in front of the lining or backing component.

SU~RY OF THE INVENTION
The present invention more specifically provides a
novel, self-lined fabric made on a stitch-through type machine
such as a Malimo machine, and which is composed of a flexible
lining material, a flexible interstratum laid on the lining
material, a plurality of optional textile yarn elements laid
on the interstratum in the general warp direction, and knitting
thread forming a multiplicity of warp-wise loop chains whose
- loops appear on the rear surface of the fabric and which bind
together into an integrated self-lined textile fabric structure
the lining material, interstratum and warp yarn elements and
which secure said components against relative displacement.
The fabric of the invention achieves an unusual and heretofore
unattainable combination of functional utility and decorative
visual effect of aesthetically pleasincJ appearance according
to the present invention through the uni~ue placement of the
functional lining of flexible material which is disposed behind
or beneath the ornamental layers of flexible interstratum and
textile warp yarn elements. In this way, the lining material
performs its function (e.g., thermal, acoustic or optical
insulation) without interfering with or obstructing the ornamental
effect of the interstratum and outer layer of warp yarn elements.
- The adjacent warp yarn elements, when employed in the
present fabric construction, can be laid on the interstratum
and lining components of the fabric in either mutually contacting
relationship or can be spaced apart from one another in the
weft direction at any predetermined distance. Desirably, such
warp yarn elements are substantially spaced apart in order to
amplify and enhance the visual effect of the open-weave "look"
characteristic of fabrics produced in stitch-through type machines. In
J~
.: -.,~ . ' :
addition/ the warp yarn elements can be laid on the interstra-
tum and lining in a substantially rectilinear or straight line
fashion parallel to the warp direction; alternatively, as des-
cribed in U.S. 3,672,187 the warp yarn or"design" elements ~so
called because of the aesthetically pleasing appearance and
ornamental effect which they impart in the fabric) can be caused
to follow non-rectilinear paths along the warp direction, and/or
in a twisted configuration in the manner disclosed in appli-
cantls copending and commonly assigned Canadian application
Serial No. 304,032 filed May 25, 1978.
The flexible interstratum upon which the warp yarn
elements are laid in forming the fabric of the present inven-
tion can be pre-knitted (e.g., tricot) or pre-woven fabric,
fibrous batting or any other continuous sheeting, one or more
layers of textile filling elements running in a general weft-
wise direction with respect to the warp yarn elements, or any
other flexible structure capable of being secured to the warp
yarn elements with knitting thread according to procedures des-
cribed in U.S. 3,672,187 and now familiar to those skilled in
the art of stitch-through fabric construction. In the case of
fabrics having the open-mesh "home spun" appearance character-
istic of casement or drapery fabrics, a flexible interstratum
in the form of a layer of more or less spaced-apart textile
filling elements is preferred.
The flexible lining or backing material component of
the fabric of the invention is preferably a layer of fibrous
non-woven fabric. The use of such lining material is parti-
cularly advantageous because of the ease with which, say, a
fibrous non-woven lining can be back-coated with a thin layer
of polymer, e~g., acrylic or urethane foam, to impart effective
thermal insulating or barrier properties while retaining the
desired casement-like "feel" and "look" of the
- 7 -
.
7~
composite fabric as a whole. Alternatively, the lining can be
any other flexible material capable of being stitched-through
by knitting thread and secured thereby to the overlying inter-
stratum and warp yarn elements. Such other lining materials
include, without limitation, elastomeric foam sheeting made of
rubber or synthetic polymeric compositions such as foamed poly-
urethane and fibrous batting, e.g., continuous filament batting.
The knitting thread used to bind together into an in-
tegrated textile fabric structure the warp yarn elements, flex-
ible interstratum and lining material can be any thread hereto-
fore used in stitch-through fabric construction and is applied
to the fabric components by means of the mechanical stitching
elements conventionally employed on stitch-through type machines.
These elements and their mode of operation are well known to
those skilled in the art and include a comb-line sinker bar and
comb-like retainer pin bar, which together define an elongated
space or work zone for fabric formation between them. The stit-
ching elements include additionally a row of pronged or bearded
pointed needles and corresponding closing wires the combination
of which is caused to move in a reciprocating fashion through
the aforesaid work zone in coaction with a row of knitting thread
guides for forming a multiplicity of warp-wise knitting thread
loop chains. In a preferred mode of operation of the machine,
alternate loops in each chain are formed with a different knit-
ting thread, and each thread forms a series of warpwise loop
chains. The loop chains formed can be any type familiar to
those skilled in the art, although loop chains of the type
characteristic of the well-known half-tricot stitch configura-
tion are preferred when the fabric includes warp yarn elements
because of the normally greater structural
~;~ - 8 -
~ :...
3L097~38
integrity imparted to the overall fabric by the half-tricot stitch
knitting thread network. In such cases the fabric components are
engaged and held together by the knitting thread on the rear side of
the fabric by the loops o the half-tricot stitch network and on
the front surface by the diagonal courses formed by the knitting
thread. In this way the warp yarn elements are "lapped" around
the interstratum and lining material by the knitting thread to
achieve an integrated fabric structure. In cases where the ODm-
posite fabric of the invention involves only the "interstratum"
(e.g., an outer surface layer of textile filling elements) and
lining material, the knitting thread can be employed in either
the half-tricot or chain loop chain oonfiguration to form an
article of manufacture having acceptable structural integrity.
In one embodiment of the fabric of the invention, at
least two warp ~arn elements can be laid on the substrate along
non-rectilinear paths in the warp direction thereby creating a
design effect which serves to augment the aes-thetically pleasing
appearance of the fabric. More partlcularly, such warp yarn
"design elements" can include portions o~ substantial length
extending diagonally, relative to the warp direction, along
straight lines or curving substantially uniformly. The design
elements can be disposed in groups composed of at least two
adjacent elements following a substantially identical pattern.
Alternatively, adjacent design elements can be laid on the
flexible substrate to form different patterns, e.g., wherein they
form the same pattern but one is reversed relative to the other.
m is ~abric design feature and an apparatus and method for
achieving it, which can be practiced in conjunction with the
present invention, are described respectively in V.S. 33672,Z87,
8~
particularly at column 1, line 31 through column 3, line 44, and
U.S. 3,677,03~, particularly at column 1, line 44 through column
8, line 22, which disclosures are incorporated herein by refer-
ence.
The improved fabric of the present invention is made
possible by a unique process utilizing a novel apparatus in con-
junction with stitch-through type machines. The apparatus per-
forms the function, never heretofore achieved, of continuously
supplying and guiding the flexible substrate lining material to
lQ the work zone of the stitch-through type machine such that the
flexible interstratum is laid on top of the lininq material and
the warp yarn elements are laid on top of the interstratum, and
all three camponents of the fabric are secured together by ~lit-
ting thread to form an integral textile structure in a continuous
operation, In its essential features the apparatus comprises,
in combination, means for continuously supplying lining material
to the stitch-through machine, means for colltinuously withdrawing
lining material from the supply means, and means for continuously
guiding the withdrawn lining material to the work zone of the
machine independently of the other fabric components and applying ~ -~
the material to the flexible interstratum and optional warp yarn
elements so that the interstratum is interposed between the lining
material and the warp yarn elements.
In a preferred embcdiment of the apparatus of the in-
vention, the means for supplying the lining material to the
; machine ~s a supply roll or beam of said material, the means for
withdrawing the lining material from the supply means comprises
two or more driven feed rolls, and the means for independently
guiding the withdrawn lining material to the work zone of the
machine and applying said material to the flexible inters-tratum
-- 10 --
7~
and warp yarn elements comprises a smooth slide plate, e.g., of
polished metal such as brass or stainless steel, disposed upstream
from the work zone of the machine and adapted to receive the lining
material in sliding contact therewith and to direct said material
to the work zone at a point such that -the interstratum is inter-
posed between the lining material and warp yarn elements in a
continuous operation.
In its broad aspect, the process or method of the present
invention includes the steps of (a) delivering a flexible lining
lQ material to the above-described elongated work zone of the stitch-
through type machine; (b) delivering a flexible interstra-tum to the
work zone conjointly with and in superimposed relation to the lining
material; and (c) delivering a plurality oE textile desiqn elements
(warp yarn elements) to the work zone conjointly with and ir. super-
imposed relation to the linin~ material and interstratum; ancl
(d) binding together the superimposed lining material, interstratum
and warp yarn elements at the work zone of the machine by warp-wise
knitting thread loop chains to form an integrated structure which
is the fabric of the present invention in greige form. Such greige
goods are suitable for further processing to finished fabric accord-
incl to art-recognized procedures, e.g., dyeing, drying, resinating,
and the like.
It is a feature of the present apparatus and method that
the lining material is delivered to the work zone of the stitch-
through machine independently of the flexible interstratum com-
ponent. In this way, it has been discovered that each of the
fabric components can adjust itself to the forces exerted by the
stitching elemen-ts without mu~ual distortion. Whereas conventional
wisdom suggests applying the lining material to the filling hooks
a7~38
of the machine followed by overlaying the interstratum onto the
same hooks as a means of delivering these two ccmponents to the
work zone of the machine, such an approach has in fact been found
to result in distortion of the assembled fabric.
In the method of the invention, knitting thread is
employed in the manner described hereinabove to form a multipli-
city of warpwise loop chains to bind together the warp yarn
elements, interstratum and lining material with the loops
appearing on the rear surface of the composite fabric. Usually~
alternate loops on each chain are formed with a different
knitting thread, and each thread forms a series of warpwise
loop chains, preferably in the manner of a half-tricot stitch
configuration, or, in cases where the fabric is made up of
interstratum and lining material without a top layer of warp
yarn elements, a chain stitch configuration.
It is a further feature of the invention that the pre-
sent method can be carried out in the manner described above
while at the same time guiding the warp yarn "design" elements
back-and-forth in a direction substantially parallel to the rows
2a of stitching elements to thereby cause each design element to
; move back-and-forth within the elongated work zone past a
plurality of needles. Equipment and procedure for imparting this
additional design feature to the fabric of the invention are
described in the aforementioned V.S. 3,677,034. In using this
procedure, the design elements are guided back and forth in re-
ciprocating motion whereby a pattern of design elements is formed
on the fabric in which substantial lengths of each design element
- 12 -
1~ 1(1 97~8
1 lextend diagonally, relative -to the warp direction. For e~ample,
2 the design elements can be guided back and forth at either constan
or, more desirably, varying speed, e.g., sinusoidally, so as to
4 form a pattern in which substantial lengths of the design elements
5 are laid on the substrate in a corresponding straight line or,
6 e.g., uniformly, curved fashion. In a further variant, two
7 groups of design elements can be delivered to the elongated work
8 zone and guided back and forth therein independently or in cor-
9 responding phased relation to each other, thereby forming a patter
10 of design elements on the fabric in which the two groups of design
11 elements form different or substnatially identical patterns,
12 respectively. In the former case, one group of design elements
13 can be maintained in phased but opposite relation to the other
14 group, whereby a pattern of design elements is formed in which
15 the two groups of elements form i.dentical patterns, but one is
16 reversed relative to the other. In yet another embodiment, the
17 design elements can be given a periodic "twist" configuration
18 in the manner described in applicant's aforesaid copending appli-

DESCRIPTICN OF THE PREFERRED EMBODIMENTS
In the following description, the corresponding
elements as shown in each figure o the drawings are given the
same .reference number, and letter suffixes are added to
designate specific ones of these elements where necessary.
In the embodiment shown in FIG. 1, the warp yarn
elements 1 are laid on a flex.ible interstratum composed of a
layer of spaced-apart textile filling elements 2 which in turn
is laid on a flexible lining material 3 cc~osed of an
; 2Q. elastc.meric foam sheet to provide a self-lined fabric according
to the present invention. The warp yarn elements 1, filling
elements 2 and lining material 3 are secured in their relative
positions by means of knitting thread 4 which forms parallel
rows of warp-wise loop chains with the loops appearing on the
rear surface of the fabric, i.e., behind the lining material.
The knitting thread 4 shown in FIG. 1 is employed in a half-
tricot stitch configuration in which diagonally-extending
portions of the kni-tting thread cross between adjacent loop
~ca74~
chains on the front surface of the fabric. Each pair of adjacent
loop chains shares two knitting threads, alternate loops of each
chain being part of a first thread and the running loops being
from a second thread, to form the half-tricot stitch. Warp
yarn elements 1 are also referred to as "design elements"
because of the aes-thetically pleasing appearance and orna-
mental effec-t which they impart to the fabric as a whole,
either as shown in FIG. 1, or by virtue of any of a number of
non-rectilinear configurations with which they can be applied
to the lining material and interstratum as illustrated in
FIG. 2.
FIG. 3 shows the manner in which the knitting threads
regularly penetrate the lining material 3 at the underside oE
the fabric o:E FIG. 1 comprising a layer of warp yarn elements
(not shcwn) laid on an interstratum of textile filling
elements (not shown) which in turn is laicl on the lining
material 3 composed of a continuous sheeting made of elasto-
meric foam so that the chain lcops of a half-tricot stitch
configuration appear behind the fabric. In this wa~ the wc~rp
yarn elements, interstratum filling elements and lining material
3 are secured or "lapped" together to form a unitary self-
lined structure by the knitting threads 4 which lock the three
other cc~mponents of the fabric in position relative to one
another. In fabrics of the type illustrated in FIG. 1 and
FIG. 3, the elastc~meric foam lining material 3 is normally
employed in thicknesses varying from l/32nd of an inch to
akout 1/2 inch depending on the particular use for which the
fabric is intended.

1 I In the embodiment depicted in the photogra~h of FIG. 4,
21 wherein the scale a-t the left is graduated in inches, -the :
31 fabric comprises a layer or interstratum of spaced-apart textile
4 ¦filling elements 50 laid on a flexible lining material 51
5 ¦composed of a continuous fibrous non-woven batting to provide, . '
6 ¦a self-lined fabric according to the present invention. The
7 ¦selvage of the layer of spaced-apart filling elements extends
8 ¦ laterally beyond the edge of fle~lble lining material in keeping
9 ¦with the aforementioned feature of the process of the inven-tion ,,
10 jwhereby the lining material is delivered to the work zone of the
11 machine independently of the interstratum, the latter being applie 1 :~
12 ~ to the filling hooks exclusive of the lining material. The ¦ :
13 ¦ filling elements 50 and lining material 51 are secured in -their
1~ ¦ relative positions by means of knitting thread 52 which forms
15 ¦ parallel rows of warp-wise loop chains applied in a chain-stitch
16 ¦ configuration as depicted in F~GS. S and 6, which also show
17 ¦ more clearl~ the placement and appearance of the non-woven lining
18 material 51.
19 In the embodimen-t shown in FIG. 7, a composite fabric,
which is made of a layer of filling elements 53 secured to a
21 ¦ non-woven backing or lining material by means of thread 5~ in a .
22 I chain-stitch configuration, is back-coated with a flexible ~
: 23 I acrylic-type foam resin 55 as can be seen by reference to FIG. 8 ¦
2^~ ¦ and FIG. 9.
Referring to FIG. 10, there is illustrated an embodi-
2b ¦ ment of the apparatus 10 and method for producing a self-lined
27 fabric of the present invention in a stitch-through type machine
2~ such as a Malimo machine (partially shown in schematic) wherein
23 the apparatus feeds in lining material between the filling chains ¦
of a Malimo-type machine under controlled -tension in order to
-17- ` :
!
7~
form a novel fabric with warp and filling yarns and a lining
material stitch-bonded to the warp and filling yarns in one con-
tinuous operation. A beam or roll 11 of lining is adapted to
supply lining material 12 to the machine by means of driven feed
rolls 13a and 13b which coact to withdraw the lining material
from the supply roll. Guide rolls 14a, 14b and 14c serve to
govern the pathway followed by the lining material 12 beneath
the machine operator's platform 31 and direct the lining material
to guide plate 15 over which the lining material passes in slid-
lQ ing contact therewith on its way to the work zone or stitching
point 16 of the machine independently of the other feed com-
._ :
ponents of the fabric. The entrance end 17 of guide plate 15
is beveled or sloped downward to smcothen the initial contact
between the plate and moving lining material. Likewise, the
exit end 18 of the guide plate 15 is beveled or sloped downward
to direct the traveling lining material l:oward the work zone of
the machine while preventing the lining material from under-
going abrupt changes in direction or contact with abrasive or
sharp edges. The guide plate 15 is made of a smooth, wear-
resistant material, preferably ceramic or polished metal or
steel.
The work zone 16 of the machine defines the location
where the stitching elem~ents, e.g., sewing needles, closing
wires, sewing thread guides, sinker bars and retainer pin bars,
coact in mutual synchronization to join the fabric components
into an integral textile structure. These stitching elements
are denoted by reference numeral 19. The warp yarn feed com-
ponent of the fabric is made up of a plane of parallel yarn
ends 20 which are supplied to the machine by any convenient
means (not shown), e.g., from a beam or creel, and fed to the work
zone of the machine in the direction of the yarn axes by guide
- 18 -
lOq7488
1 roll 21. The interstratum component of the fabric produced by
2 ! the apparatus of FIG. 10 is made up of a plane of parallel
3 ~ textile filling yarns or elements which are supplied to the
4 j machine from one or more creels (not shown) and fed to the work
5 ¦ zone of the machine in a direction substantially perpendicular
6 I to the filling yarn axes by means of a pair of opposed
7 parallel ~ws of filling hooks, each row being fitted to a
8 chain drive whicll is driven by rollers 23a-23d o~ a circular
9 pathway deno~ed by reference numeral 24. The textile ~illing ~:
iO elements are applied to the filling hooks by means of filling
11 yarn carrier 25 which comprises a set of reeds mounted on a
12 reciprocating carriage.and through which the filling elements 22
13 pass while the filling carriaye passes back and forth between
l_ the rows of filling hooks. In cases where the interstratum
is other than a layer of textile fi:lling elements, the filling
16¦ hooks can be appropriately modified in a nlanner which will be
17 apparent to those skilled in the art of stitch-through machines.
18 It is a feature of the apparatus and method of the
,9 i~vention that ~he lining material 12 is fed to the wor~ zone 16
of t;ne machine so that the interstratum of filling elements
21 is disposed between the layer of warp yarn elements and lining
22¦1 material at the point where the fabricc~mponents are joined -:~
23l together with knitting thread into an integral textile structure .:
2~ by the stitching elements 19.
The self-lin~d fabric produced in the work zone ol the
26 machine is withdrawn therefrom along the pathway indicated by
~7 ¦ reference numeral 26 and is directed by means of driven rolls
