METHOD AND onnrrroar. MI TURE FOR PRODUCING BROCADED mnxrrnns.

- N Drawing".

The present invention relates to method, apparatus, "and treating. mixtures, for producing brocaded fabrics. The'invention relates particularly to the producing oi a brocade from a fabric having a cottonback and a wool face, such as a corduroy, velvet, or plush, but is applicable to fabrics of other combinations of backing and facing. 'The invention further reli-ites to the producing ot a brocade and the, dyeing oi the different parts of the brocade in side by side, intermingled, or simultaneous steps of one proc ess. late s to the production of pile textile in which the are oi different materials,

a brocade from a pile and backing as wool and cotton respectively, by using a chemical which will attack the wool but not tlre-cotton,the mixture being applied to the pile over designed areas; I

According to myinventiona brocade of velvet, plush o other textile having pile fibres, is made removing designed areas of the pile thereof by means of a chemical which will destroy the integrity of the fibres ot' the pile at the designed areas. This destruction of the pile fibre may involve the solution of the fibre or the disintegration thereof or both. The fibre destroying or burning mixture maybe applied by printing it on by means of intaglio plate or rolls. The mixture may then be permitted to have time to attack the fibres oi the pile to which it was applied and the destruction of these [ibres may be hastened by the application of heat or moisture or both;

During the process of removing designed areas oi? the pile to produce a brocade from a suitable textile dye may be applied to the textile either to a portion or all of that part o i? the backing from which the pile is removed or to'the pile which is left or to 'both in one or more colors. Color or dye may be applied to the backing by mixing it with and applying it to the textile with the Jurning mixture. I The colors may be; printed on the cloth in a textile printing machine of the sort well known in the art and means may be provided for applying the burning mixture thereby.-

Other objects of my invention will appear from the specification and the claims.

According to this invention, in making a brocade from a velour having a cotton back: ine and a woolpile, a chemical mixture for destroying a part of the pile is made up 0t The invention'ifurther particularly re-- such for example Application filed October 9, 1525. Serial No. 61,,519-

the following ingredients and quantities:

about 60 :parts of 15% caustic soda solution by volume, one part of 15% sulphuric acid, and 140 parts 10% gum arabic solution or other strengthcommonly used for printing on textiles. I I 1 The mixture is applied to designed areas of the textile by printing it on the pile face with intaglio plates or, preferably, by means of a iriiiting machine such as is commonly used on textiles. The textile is run from the printing machine to and through a steaming chamber where it is exposed to the heat and moisture. of the steam for about thirty minutes, whereby the pile fibres of the areas printed are disintegrated and destroyed.

1 After the steaming the cloth is dried at about 200 F.

After drying the disintegrated fibres these are brushed from the cloth, after which itis washed and dried and when necessary again brushed to bring up the fibres of the pile.

Ai'ter this treatment the velour, or any.

other like textile, has all the pile fibres in 5 the unprinted areasin as good condition as before and the line between the unprinted areas of the pile and the backing which now shows is sharp and clear. The burning mixture does not spread from the prmted areas and sharp pointed, designs and finely linedides'igns may be made. The cotton of the backing is strengthened by the process and is tightened about the fibres of the pile areas not printed. The pile iibres'printed areremoved even entirely through the weave o l? the back.

Dyes may be applied at thetime '01? print ing which after the process is completed will serve as decoration for the reverse side of the textile in which case hangings, tapestries, and the likemay bemade which will not require lining.

Although I have shown and described and have pointed out in the'annexed claims certain novel features of the invent-ion, it will be understood that various omissions, substitutions and changes in the several steps of the process and in its operation may be made by those skilled in the art without departing from the spirit of the invention.

I claim:

1. The method. of making a brocade from a textile having a cotton back and a pile. face ofwool-which comprises impregnating designed portions of the pile face with a mixture comprising a carrier and {30 parts a textile having by Volume of 15% solution of caustic soda to one part of a 15% Water. solution of sulphuric acid, permitting the mixture to disintegrate the impregnated portions of the pile, and then removing disintegrated pile fibers and any remaining inpregnating 1niX- ture. i
