- PROCESS OF PRINTING FABRICS.

K0 Drawing.

To all whom it may concern:

Be it known that I, GEORGE PRmoLD, a citizen of the United States, and a resident of Linwood, county of Delaware, State of Pennsylvania, have invented certain Improvements in Processes of Printing Fabrics, of which the following is a specification. My invention relates to certain improvements in the process of printing designs upon woven fabrics, such as carpets, tapestries, &c.

One object of my invention is to improve the process of printing upon these materials so that the color design will extend a considerable depth into the body of the fabric.

A further object of the invention is to use a dye, such as anilin, .or its equivalent, as the coloring matter and to deposit it on the fabric with a vehicle, then removing the vehicle, leaving the coloring matter in the fabric. i

The fabric after being woven is passed through a printing machine of the type illustrated in thepatent granted to William H. Waldron on the sixth day of July, 1915, No. 1,145,821.

This machine consists essentially of a frame having. a series of printing blocks and means for reciprocating said blocks and a series of pigment carriers, which are arranged to reciprocate under the several printing blocks 50 as to supply the blocks with the coloring matter to be impressed upon the fabric. The pigment I use in the present instance is made of anilin colors and is mixed with starch, flour, or equivalent.

material, to give it sufficient body. The fabric is intermittently fed through the machine and the impressions are made by the printing blocks, the number of printing blocks depending upon the design and the number of colors desired. The printed fabric passes from the machine and into a. steam chamber having rollers at each end carrying bands at each side to which the fabric is clamped by any suitable clamping device.

The steam in. the chamber causes the anilin colors to pass into the fibers so that the colors that were deposited on the surface of the fabric run and extend into the Specification of Letters ratent. Patented Jan. 29, 191$.

body of the fibers. Afterthe goods as from the steam chamber they are festo ned in a drying chamber by looping the fibers over in the ordinary manner of festoon drying.

- suitable bars, which are traversed on rails This drying evaporates the moisture in'the 7 material so that the starch or flour become dry, leaving the anilin colors in the fibers. In

order to remove the starch or flour, or like material, that is used to carry the anilin dyes, I pass the fabric through a brushing machine consisting of a series of abutments opposite brushes. There are a number of these brushes and at intervals there is a series of beaters consisting of a rotating drum having a series of bars thereon, which strike against the back of the fabric. The brushes act against the face of the fabric, while the abutments support the back "of the fabric. These brushes remove the dry flour orstarch and the action of the heaters is to cause any particles of starch or flour that have ai'ned access to the body of the fabricto By the above process, I am enabled to print elaborate designs and to cause the dye to penetrate the full depth of the fabric so e removed therefrom and when the fabric passes that the entire surface of the fabric has the same appearance as a fabric where the strands are dyed prior to being woven.-

More elaborate designs can be made by my improved process than by present methods of printing fabrics and the cost of the process of printing is considerably reduced.

Although I have described the use of starch and flour as a carrier for the coloring matter and although I have described anilin colors as used, it will be understood that other vehicles may be used which can be converted into powder andremoved by colors may also be used Without departing from the essential features of the inventiom I claim:

1. The process herein described of printing woven fabrics, said process consisting in mixing a color capable of dyeing a fabric and a vehicle capable of being dried and dusted out of the fabric printing the fabric with said color, then su jectin'g the printed fabric to heat and moisture so as to cause the color material to enter the fabric, then drying the fabric so as to reduce the "ehicle to a solid, then removing the vehicle in the form of dust, leaving the coloring in the fabric.

2., The process herein described of printing Woven fabrics, saidprocess consisting in mixing a color capable of dyeing the fabric and a vehicle capable of being dried and dusted out of the fabric,print-ing the fabric With said color, then subjecting the printed fabric to steam so as to cause the oloring matter to enter the body of the fabric, then drying the fabric so as to reduce the vehicle to a solid, then brushing out the Vehicle in Leashes the form of dust, leaving the color in the fabric. 7

3. The process herein described ofprinting Woven fabrics, said process consisting in printing a surface of thefabric With the color carried by a vehicle of starchy material, then subjecting the printed fabric to the action of steam so as to cause the coloring matter to travel into the fiber of the fabric, then drying the fabric so as to solidify the starch, and finally subjecting the fabric to a beating and brushing action so as to remove the starchand flour, leaving the coloring matter in the fabric.

4:. The process herein described of printing Woven fabrics, said' process consisting in printing the fabric With a composition consisting of an anilin color and a starchy vehicle, subjecting the fabric to the action of moisture and heat to cause the anilin colors to penetrate the fabric, then drying the fabric to solidify the vehicle, then removing the vehicle from the fabric, leaving the anilin color therein, and then sizing the back of the fabric.

In Witness whereof I affix my signature.
