In the hitherto known methods for producing ground off, the washable portions being thenr'eprinting stencils for cloth printing, the pattern is moved. painted on the plate made of gauze or metal iab- Sulphite waste liquor is a commercial product ric by means of water glass and, after the stencil and a residue from the manufacture of cellulose,

'I'his method, howcellulose is freed. ever, produces a pattern which is not sharp and The method is employed in the following manconsequently cannot be employed for iine patterns ner: because, owing to the washing out of the water The printing frame in which the gauze (Fig. 1)

The gauze is It has been found that the patterns can be carthen coated with a soluble auxiliary coating of ried out very much smaller and therefore absozinc-white bound with sulphitelye (Fig. 2),which lutely sharply if they are not applied directly onto has the property of bridging even wide meshes the gauze but onto a soluble auxiliary coating, for and consequently does not penetrate vto the other example of varnish from which they are removed side of the gauze. 'I'he penetration of the coating before the Washing out. By the employment of is prevented by the addition of suiiicient zinc two different auxiliary substances for producing white.` When the coating has completely dried,

It is not new to make textile stencils by succesfor which purpose a viscous likewise soluble paint sively treating a surface of gauze, silk or wire is employed having a similar composition to the y fabric with varnishes soluble in water and insoluauxiliary coating, the zinc-white being however 25 ble in Water. 'I'hese methods have, however, notpreferably coloured with aniline red, and this hitherto been generally introduced because in this pattern enters the meshes of the gauze and pene- Yinstance the pattern is formed by dissolving the trates the auxiliary coating with which it intipaste and consequently the contours of the patf mately unites. After the removal of the auxiliary tern are likewise damaged and ragged. Accordstencil the pattern remains on the gauze in relief 30 ing to the invention the pattern is applied in rewith sharp contours. 'Ihe pattern must then dry lief onto the surface by means of hardening paste completely. Whereupon the side of the gauze and a 4damaging of its contours is prevented by carrying the pattern is then coated with a var- .glrlding off. Y nish-like caoutchouc solution (Fig. 4) composed An embodiment of the invention is illustrated of one part by weight of linseed oil, one part of 35 by way of example in the accompanying drawing caoutchouc and three parts of pigments Which are in which:- intermixed and adhere tightly to the gauze. The Figs. 1 to 7 show in cross section a stencil in the blocked out parts of the stencil are therefore prodifferent stages of production. tected by the coating of caoutchouc so that they 40 Fig. 8 is a cross section of the nished stencil. are not affected during the further treatment of 40 Fig. 9 isa top plan view of Fig. 8. the stencil. When the caoutchouc coating has The invention consists in that on one side of dried, the printing frame is submerged in water the stencil support l consisting of gauze or the and the raised portion of the pattern ground oil like a tough but porous auxiliary coating 2 adaptto the surface of the caoutchouc layer covering ed to be washed oil and consisting of zinc-white the gauze (Fig.'5) by friction using iine pumice 45 bound with sulphite waste liquor isl applied on to stone. The auxiliary coating is then washed off which from the unpainted side of the gauze the from the inner side of the frame together with pattern 3 proper is applied in relief by means of the remainder of the pattern paint (Fig. 6). The an auxiliary stencil and of apaint which is viscous blocked out parts of the stencil itself remains in but capable to be washed out and which consists the caoutchouc coating with sharp contours as the 50 of the constituents of the auxiliary varnish, the varnish was applied by means of the auxiliary zinc-white of which is preferably colored with stencil. In order to prevent the finished stencil` anilne red, whereupon the side of the gauze which from becoming porous, the gauze is coated on the carries. the pattern is coated with caoutchouc 4 washed inner side with a diluted blue varnish hav- (Fig. '1), and when this blue varnish is dry, the stencil is ready for use (Figs. 8 and 9). The dilution consists of about one further component of the linseed oil.
I claim:- A method for producing stencils for printing textile fabrics, consisting .in applying to one side ,of a-gauze forming the support of the stencil an adhesive, glutinous but porous soluble auxiliary,
