wovEN CURTAIN FABRIC Filed May 6, 1959 2 Sheets-Sheet 2 ."mmmmmmmmmmmmmmn United States Patent O 2,998,829 WOVEN "CURTAIN FABRIC Harry Horowitz, 499 7th Ave., Summit, NJ. Filed May 6, 1959, Ser. No. 811,391 Claims. (Cl. 139-384) T-he present invention relates to a novel drapery fabric and it particularly relates to a method of making such drapery fabric.
It is among the objects of the present invention to make a novel drapery fabric which can be readily woven by standard procedures in a loom and which after weaving may be readily converted into a drapery fabric without additional processing.
It is a further object of the present invention to make a drapery fabric which may be directly woven upon the loom and which by simple manipulation may be converted into an attractive drape or curtain.
Still further objects and advantages will appear in the more detailed description set forth below, it being understood, however, that this more detailed description is given by way of illustration and explanation only and not by way of limitation, since various changes therein may be made by those skilled in the art without departing from the scope and 'spirit of the present invention.
In accomplishing the above objects, it has been found most satisfactory to weave a drapery fabric So that in-V cluded with the normal weft` and warp strands there will be an additional relatively heavy readily adjustable or slidable warp strands or group of warp strands which will permit the fabric to be drawn up into attractive drapery appearance or mflied appearance permitting it to be immediately utilized without further mechanical processing or sewing or stitching as a curtain or drape. 4
The relatively heavy warp strands which are responsible for this procedure should have a diameter or thickness preferably about two to three times and sometimes up toy the other weft or warp,v
four or five times the diameter of strands.' f
'I 'heir surface should be relatively smooth so that they may slide through the overloopingpor engaging warp 'and weft strands but at the same time they should maintain their adjusted position after the fabric has once been drawn up so that it will have its final curtained or rued appearance.
With the foregoing and other objects in view, the invention consists of the novel construction, combination and arrangement of parts as hereinafter will be more specifically described, and illustrated in the accompanying drawings, wherein is shown an embodiment of the invention, but it is to be understood that changes, variations and modifications can be resorted to which fall within the scope of the claims hereunto appended. f
In the drawings wherein like reference characters denote corresponding parts throughout the several views:
FIG. 1 is a side diagrammatic view showing the manner of weaving the fabric of the present invention upon a loom.
FIG. 2 is a fragmentary plan view showing the construction of the fabric after it has been woven.
FIG. 3 is a transverse sectional view upon the line 3-3 of FIG. 2.
FIG. 4 is a fragmentary plan view upon enlarged scale as compared to FIGS. 2 and 3 of the portion of the fabric of FIG. 2.
FIG. 5 is a fragmentary top perspective view showing a portion of the fabric upon a greatly enlarged scale as compared to FIGS. 2, 3 and 4.
FIG. 6 is a diagrammatical elevational view showing the manner in which the fabric has been gathered tothat it will hold n adjusted ice gether by the into.
FIG. 7 is a transverse sectional View upon the line 7,7 of FIG. 6. y
FIG. 8 is an elevational view of the portion of the fabric of FIG. 6 showing the fabric construction.
FIG. 9 .is a fragmentary diagrammatic transverse sectional view of a fabric construction upon enlarged scale showing the doubling of the heavy pull strand S with la-` warp strand. l
FIG. 10 is a fragmentary diagrammatic transverse sectional view of a fabric construction upon enlarged scale showing the tripling of the heavy pull strand S with a warp strand. w Y
Referring to FIGS. 2 to 8, the fabric may be a woven fabric with a taffeta weave such as is shown in FIG, 5 with the warp strands 51 and the filler or weftstrands 50.
The important feature of the present invention is that there is woven into the fabric a relatively heavy'strand S which is frictionally retained 4in adjusted position` between the warp strands 51 and by the Yfiller or weft strands 570 without being locked in position, as is true of the usual manner of the weft and warp strands.
This condition continues even if the fabric be finished' and even if the fabric be subsequently sized.
Desirably the strand S, two or three of which are used parallel to one another, as shown in FIGS. 2 and 6, has a dimension or thickness of about two to'three timesthe thickness of the weft and warp strands 5t) and 51 and it has a substantially smooth surface which might be slightly abraided as by frictional contact or by sand blasting so 6, 7 and 8.
In weaving this fabric the warp strands E- comeoff the usual shed and are separated by means of ing vertically postitioned heddles D`.
These heddles will form the alternating Weft .strands into the shedsV 23 and 24./
The extra strands S are fed from independent feed roller 17 over the guide rollers 19 on the shafts 18 'into' selected heddles to form fthe strands25 which are woven into the fabric by the filler placed therein bythe shuttles L.
The loom is driven from ythe shaft provided with the" fly Wheel 20 andthe follower arm 22 and the cam 21: The lay G will reciprocate backwardly and forwardly" upon the shaft 26 and the vreed M Iwill separate the ,-Warpj -will beat up the strandsto they fellstrands 51 and position; n f The woven fabric will appear as shown in FIG. 2 with groups of relatively heavy slidable or adjustable Warp strands S in the fabric R which are held in position in the manner diagrammatically shown in FIG. 5
but which lwhen drawn up will gather the fabric so that it may be used as an attractive drape or curtain of the Viennese type.
The strands S as shown in FIGS. 4 and 8 alternate so that only one or two groups of filler or weft strands are on each side thereof but for greater clarity, a larger or" smaller number are shown thereon.
Although not restricted thereto, it has been found satisfactory to double with the pulling or slipping warp S, one or two normal size warps 5'1 so as to enable the heavy warp S more readily to be drawn through the fabric to achieve the drape effect as shown in FIGS. 6 and 7.
This may be accomplished either by feeding the warp f Patented Sept. A5 19516y use of the extra warp strands woven there-gr position as shown in FIGS.V
the *reciprocat-` end S with one or more normal warp ends 51 through the same heddle eye.
However, it is preferably` accomplished by so setting the dobby mechanism so that the pulling strand S will be positioned alongside a relatively thin diameterl strand 51.
'I'he strand S may be of high tenacity rayon Aof 800 to 1500 denier and it may consist of two endshaving an organzine twist. The normal warp and lling strands may be of 75 denier acetate.
Generally the preferred weave is composed of warp and filler strands of relatively small diameter having a denier of 75 to 100 together with spaced relatively heavy warp strands having a denier of 750 to 1500.
Desirably the weave is a taifeta weave with one end up and one end down and with the heavy strand S always being included in the same iiller loop with one or more of the thin strands 51.
If desired, this heavy strand S may be shifted back and forth so that it will -be looped together with the thin warp strand on one side and then with the thin warp strand on the other side and although the main strand S is desirably of doubled high tenacity rayon, it may also consist of doubled mixed strands of nylon and rayon or of double strands of nylon.
In the preferred form, the strands S consist of nonstretchable rayon or nylon, whereas the small diameter filler and warp strands 50 and 51 of 50 to 75 denier with either bright or dull surface and permit ready slippage of the heavy strands S.
In FIG. 9 is shown the construction in which the taifeta weave represented by the over and under filler strands 61 and 62 forms a series of pockets in which there is normally only one warp strand 60.
However in the pocket 63 which receives the heavy warp strand S, there will also be doubled with the heavy strand S a single warp strand 64. This aids in the pulling and gathering of the fabric in the manner shown in FIGS, 6 and 7.
In the transverse section as shown in FIG. 10, the filler strands 70 and 71 in combination with the normal Warp strands 72 may form a standard woven fabric except for the pockets 75 which receive the heavy strand S for gathering purposes.
The heavy strand S may betripled with the normal warp strands 73 and 74 so that the heavy strand S may be most readily drawn up in respect to the fabric to give the gathered effect.
While I have shown the invention in but one form, it will be obvious to those skilled in the art, that it is not so limited, but is susceptible of various changes and modifications, without departing from the spirit thereof, and I desire therefore that only such limitations shall be placed thereupon as are imposed by the prior art or as are specifically set forth in the appended claims.
