Description

- Patented a. is, 1932 UNITED STATES CAIILLB DBEYI'US, 01 NEW YORK, N. Y.
' wm ram'rme No Drawing.
This invention relates to the production of novel color eflects by the printin of warps of arns of organic derivatives 0 cellulose.
object of my invention is to locally color 5 warps of yarns of organic derivatives of cellulose, whereby novel color effects are produced. Other objects of my invention will appear from the following detailed descript1on.
In the weaving of fabrics, a warp is first made which comprises a series of parallel yarns wound on a beam. This. warp is fed to a loom where the weft or filling is woven in to make a fabric. When yarns of organic derivatives of cellulose are employed in the warp, it is necessary to size the same in'order to impart sufiicient strength to the warp to withstand the drastic conditions to which it is subjected in the loom.
I have madethe surprising discovery that such warps, while they have the size thereon,
- may be successfully printedwith a suitable printing paste despite the presence of the size thereon.
In accordance with my invention, I locally color warps of yarns containing organic derivatives of cellulose which have thereon a suitable size, by locally applying thereto a coloring matter.
The warps to be locally colored by my invention are parallel yarns wound on a beam corresponding in length to the width'of the fabric eventuallyto be made therefrom. In
order to prevent the warp from becoming disarranged duringprinting, leases are preferably woven at intervals therein. The warp may consist of yarns of organic derivatives of cellulose, examples of which are organic esters of cellulose such as cellulose acetate,
' 4o cellulose formate, cellulose propionate and cellulose butyrate and cellulose 'ethers such as ethyl cellulose, methyl cellulose and benzyl cellulose. If desired the warp may also contain yarns ofother fibres such as silk, cotton, reconstituted cellulose, wool or flax.
Application fled September 8, 1925. Serial No. 804,803.
The warp yarns are sized with a suitable size which may contain glue, gelatin, starches, A
dextrines, etc. or any suitable mixtures of these, in order to increase the strength of suchyarns. The sized yarns then have locally applied thereto a suitable coloring matter, in any suitable manner. The. colored designs may be applied by printing with engraved or embossed rolls or blocks, or it may e applied by brushing or spraying of a suitable coloring material onto stencils placed over the warp.
The dyestufl's employed in the coloring matter may be any suitable-dye that has an aflinity for organic derivative of cellulose yarns. Examples of such dyestuffs are insoluble anthraquinone dyes in the unreduced state dispersed in aqueous dispersions by means of a dis ersing medium such as Turkey red oil. ther suitable dyes such as the :basic dyes may also be employed. The coloring matter also contains suitable thick- ,eners such as gum arabic, gum tragacanth,
British gum, dextrine, starches, etc.
After the coloring matter is applied locally to the warps, they may be dried on rotating heated drums or cans or in any other suitable manner, and, if desired, they may be steamed or aged. The warps, when treated in the above manner, are ready for weaving and may be woven with a weft or filling of yarns of organic'derivatives of cellulose or of other fibres such as silk, cot.-' ton, etc. The filling yarn may be of any desired color. I
An advantage of my process is due to th fact that the thickener of the printing paste, when it is retained on the warp, further in: creases the strength of the same and acts as a size during the weaving operation. Ins5 stead of weaving the warp to make a woven fabric, the warp may be knitted to form a warp knitted fabric. a
After weaving or knitting of the printed warp, a fabric s produced having subdued fabrics containing cellulose acetate yarn.-
Example A warp is employed that consists of parallel yarns made of cellulose acetate and having leases woven therein at intervals of, say one yard, to retain the warp in place during printing. The warp yarns are sized prior to beaming with an appropriate size containing gelatin, glycerine, castor oil and water. The Warp is fed to an ordinary printing machine, where it is printed by means of suitable engraved rolls with a printing paste that is ordinarily used for printing An example'of such printing paste is:
The printed warp is then dried by being passed around rotating heated drums or cans, and if desired, may be aged by steaming. The warp is'now ready for weaving and this is done in any suitable loom after the leases have been removed. The weft or filling may be a yarn of organic derivatives ofcellulose r of any other fibre and may be of any 'esired color. Despite the presence of the size on the warp yarns, the printing paste produces clear and well colored designs thereon.
It is to beunderstood that the foregoing detailed description is given merely by way of illustration and that many variations may be made therein without departing from the spirit of this invention.
Having described my invention, what I claim and desire to secure by Letters Patent V 1. In the method of producing warp print' effects, the step of printing a warp containing organic derivative of cellulose yarns and having a size thereon, with a paste containing an insoluble 'anthraquinone dye.
2. In the method of producing warp print eflects,the step of printing a warp containing cellulose acetate yarns and having a size thereon, with a aste containing an insoluble anthraquinone ye.
, 3. The method comprisin passing a warp of cellulose acetate yarn having leases at intervals therein, which yarn has a size con-.
taining gelatin thereon, in contact with a rotating printed roll which applies a printing paste containing an inso uble anthra quinone dye locally t ereto, passing the warp over drying drums and then converting said warp into a fabric. y
