JULIUS HÜBNER in CHEADLE HULME.

The invention relates to a new method by means of which brocade effects similar colored patterns can be produced on fabrics. The method is particularly suitable for use on cotton fabrics. The cotton fabrics are in a known manner with mercerizing solutions, for. B. with caustic Soda and the like, and the tissue either completely or only

ίο partially from the mercerising liquid Washing free. Tissues that have been treated with weak mercerising fluids can may be used without being washed beforehand.

The tissue is after the described: treatment in the wet state (without stretching or with extremely little stretch) with one or more patterns or with lines or other engravings embossed or pressed in the usual way.

For embossing or pressing, rolls, plates, molds and the like can be used in cold or heated condition. As mentioned, the goods are during the Embossing or pressing while wet. The tissue is therefore allowed after the treatment not dried with the mercerising liquid and before embossing or pressing will. The fabric is then dyed immediately, or it is first dyed before pickled. If necessary, the goods can be embossed or pressed and before dried before dyeing.

It has been found that completely new effects are achieved when fabrics treated in this way are dyed. Dark 40

For example, patterns on a light background have been used so far manufactured by means of so-called half-etching. Similar effects can now be obtained ' when fabrics treated in the manner described are dyed. It was found that the pressed parts were a have a lower absorption capacity for dyes and stains than the non-pressed ones Parts. The difference in the degree of coloration is due to the depth of the Engraving, the pressure under which the pieces are pressed, the temperature of the rollers, etc. It is therefore possible to add various nuances to the pressing with a roller and the like produce.

All known dyes can be used for dyeing, either individually or in combinations, are used, for example the nouns cotton dyes, alizarine, basic Dyes, indigo, aniline black and the like.

Special effects are obtained when the tissues after treatment with the Mercerizing liquid stained or colored and this afterwards before drying, i.e. in wet, embossed or pressed.

Dyes, stains and the like can also be used at the same time as embossing or pressing and the embossed or pressed fabrics can either before or after drying by known methods can be printed with dyes, etchings, etc.

Although the effects achieved in this way have a certain resemblance to have etched patterns, they are different from such patterns because the pressed ones Parts show a better shine,

while the other parts have less gloss.

The effects achieved using the new method therefore appear more vivid than those which have so far been achieved by one of the known methods.

As a result of the embossing or pressing of the fabrics when wet and practical without stretching one therefore obtains plastic ίο effects which are similar to those which were previously made by weaving (so-called brocade effects).

It should also be emphasized here that the effects achieved in this way are much more authentic are as similar, which are made by embossing, but before their production was dried after embossing.

Godfather NT-A ns PRUCH: Process for producing colored patterns similar to brocade effects on fabrics, characterized in that fabrics treated with mercerising liquids when wet, embossed or pressed with no or almost no stretching, and either before pressing, at the same time as pressing or after pressing, they can be stained and colored in the usual way.
