PROCESS FOR TREATING TEXTILE FABRICS.

Specification of Letters Patent.

Application filed March 2, 1914. Serial No. 822,004.

Patented Oct. 20, 1914.

To all whom it may concern:

Be it known that I, CHARLES M. Mo- LEOD, a citizen of Great Britain, residing at New York, in the county of New York and State of New York, have invented certain new and useful Improvements in Processes for Treating Textile Fabrics; and I do hereby declare the following to be a full,

clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same.

My improved process of printing textiles has for its object the production of woolen fabrics bearing an ornamental design of a permanence and appearance hitherto not attainable. More especially, by the process to be hereafter described, I am enabled to produce a printed woolen blanket with a permanent and durable design which is superior in appearance to a woven design, as I am enabled to secure a variety of coloring not attainable in a purely woven pattern.

To produce my improved printed fabric I proceed as follows I prepare a woolen fabric in' the ordinary manner by weaving and then subject this rough unfinished cloth to a process of sulfurization, that is to a bath of sulfurous acid or sulfur dioxid gas which tends to bleach the fiber and prepare same for the subsequent process of printing;

This fabric in its ordinary form be ore napping has a thickness of approximately one fourth of an inch and presents a felted roughened surface. This cloth is then printed in the ordinary manner either by block printing or by spray printing, care being taken to use permanent colors which will not be discolored b the subsequent finishing process and which are not changed by the woolen fiber. In order that the design may be' impressed upon the fabric throughout its thickness, it is required that the printing be applied with considerable necessary were the printing on the surface merely. After the printing in one or more colors is completed, the cloth is finished by steaming which tends to distribute and fix the color uniformly throughout the thickness of the fiber. Lastly the napping process is resorted to, so that a fabric of approximately one fourth of an inch thickness will attain double this thickness and the soft appearance of the ordinary blanket. By printing the fabric before the napping operation,.a softness of outline and a delicacy of tone is obtained which it is not possible to obtain by printing on the napped fabric. This enables me to reproduce on blankets the emblem or crest of societies, clubs, hotels, etc., in theirproper colors and also to produce borders on blankets which will be in harmony with the decorations of the room in which they will be used.

I am aware that it is old in the art to print textiles by means of block printing or spraying, but what I have discovered is the art of so treating blanket fabrics so as to produce clear and permanent designs in one or more colors, such designs penetrating the entire thickness of the fabric so that the design appears in a uniform manner throughout the same.

What I claim is: I

1. A process of treating textile fabrics by block printing the woolen fabric and subsequently napplng the same.

2. A process of treating Woolen fabrics by block printing said cloth with inks not affected by the woolen fiber, then napping said fabric.

In testimony whereof I afiix my signature in presence of two witnesses.
