m f il Patented June 24, 1930 UNITED STATES PATENTl OFFICE JOSEF MAHLER, OF NEMECKY BROD, CZECHOSLOVAKIA, ASSIGNOR T0 FIDELITY MACHINE COMPANY, OF PHILADELPHIA, PENNSYLVANIA, A CORPORATION OF DELAWARE PROCESS OF PRODUCING PATTERNS ON PLATED KNITTING AND THE CORRESPONDING PRODUCT Application filed October 10, 1927, Serial No.

It is known in connection with Woven fabrics to produce patterns by a process of carbonization wherein part of the texture is destroyed by means of corrosive agents.

The present invention consists in applying the above process to plated stockings or other plated knitting, the two'web portions being made of diHerent kinds of materials such as cotton and Wool so that a patterning can subsequently be produced by applying to the top surface, for instance by printing, a corrosive which only attacks the plating and leaves the ground Work to appear through the latter.

In this manner a Jacquard effect can be produced by very simple and inexpensive means.

By the present process, it is possible to obi tain a design outlined by a sharply defined line which will follow a predetermined configuration irrespective of the outline of the individual stitches of the foundation fabric. Designs have been knit into t-he fabric by means of plating, but it has never been possible heretofore to produce a design in a knitted fabric in which the outline of the design will follow a sharply defined line, for, of necessity, the knitted design is defined by the outlines of the individual stitches of the foundation fabric upon which the plating stitches are laid, the plating stitches assuming the same form as that of the underlying foundation stitches. With the present invention, however, if desired, the outline of the design may be made to cut across the plating stitches, a portion of the stitch being removed While the remaining portion constitutes a part of the sharply defined line.

For the etching out ofthe cotton, the pattern is printed with sulphuric acid. A solution of caustic soda may be used for etching out the Wool.

In the accompanying drawing, Figures 1 and 2 respectively illustrate pieces of plated knit goods 1, having areas 2 of predetermined outline in which the plating has been removed, in accordance with the process above set forth, leaving the groundwork 3 exposed to view. In Figure 2, the outlines 4 and 5 of the areas 2 are shown as cutting across the plated stitches 6, thereby sharplyf defining 225,402, and in Czechoslovakia .Tuly 1, 1927.

the outlines of the plated areas 7 irrespective of the outlines of the individual stitches of which the fabric is composed.

I claim:

l. A process of producing patterns on plated knitting consisting in forming the plating and the ground Work out of different materials, and printing the pattern on the knitting with a corrosive agent adapted to destroy the plating material Without attacking the ground work.

2. A process of producing patterns on plated knitting consisting in forming the ground work out of wool and the plating out of cotton, and printing the pattern on the knitting with sulphuric acid.

3. The process of producing designs on plated knitting, outlined by a sharply defined line following a predetermined configuration irrespective of the outlines of the individual stitches of the foundation fabric, the ground Work 0f the plated knitting being of one material and the plating of another material which comprises exposing a portion of the plated knitting to the action of a corrosive agent adapted to destroy the plating in predetermined areas according to the design desired without attacking the ground work or the plating of other areas, allowing the corrosive agent to 4act upon and destroy the susceptible plating material in t-he predetermined areas to which it is applied, and thereafter freeing the fabric of the corrosive agent.

4. A process of producing patterns on plated knitting, the groundwork being of one material and the plating of another material, which comprises exposing a portion of tbe plating to the action of a co1'- rosive agent adapted to destroy the plating in predetermined areas according to the design desired without attacking the groundwork, allowing the corrosive agent to act upon and destroy the susceptible plating material in the predetermined areas to whichit is applied, and thereafter freeing the fabric of the corrosive agent.

5. A plated knitted fabric, the plating of which is of one material while the groundwork is of another material having a design formed thereon, the plating having been removed in predetermined areas by a corrosive agent which destroyed the plating Without attacking the groundwork, the groundwork appearing through the plating in the said predetermined areas to form the design.

6. A plated knitted fabric, the plating of which is of one material While the groundwork is of another material having a design 10 thereon outlined by a sharply deined line following a predetermined configuration irrespective of the outlines of the individual stitches of the foundation fabric, the plating having been removed in predetermined areas 15 by a corrosive agent which destroyed the plating without attacking the groundwork, the groundwork appearing through the platf ing in the said predetermined areas to form the design.

o 7. A plated knitted fabric, the plating of which is of one material while the groundwork is of another material having a design formed thereon, the plating having been re moved in predetermined areas by a corrosive 5 agent which destroyed the plating without attacking the groundwork to form a predetermined design.
