Embodiment Construction

[0024] refer to figure 1 , for figure 2 The fabric 10 of the illustrated cylindrical stencil 12 comprises, parallel to the axis A of the cylinder, threads 14 of diameter d made of a thread material having low elasticity or stretchability and slack (creep of the material under tension). Manufactures such as PET, polyethylene terephthalate (PETP) fibers produced by a melt spinning process, or PEN. The low stretch - in combination with the low sag - facilitates that the stencil 12 provides better alignment than a polyamide (PA) fabric stencil.

[0025] The wire 16 of diameter e is formed from a wire material with high wear resistance, for example polyamide such as PA2000. At this point, the knot or bend 18 that occurs on either side of the wire 14 defines two parallel planes E and E 1 .

[0026] A stencil 12 composed of this fabric 10 has a higher abrasion resistance than a stencil composed of PET, thus providing a higher coating strength. In addition, thicker wear-resistan...

Abstract

The invention relates to a fabric for the manufacture of stencils for rotary screen printing, the fabric being formed from crossed threads of long plastic fibers. The fabric may be coated with an emulsion, especially a photosensitive emulsion. For the cylindrical stencils, the threads of the fabric are made of different materials. The thread material of the fabric having threads oriented in the direction of the longitudinal axis of the cylindrical stencil is less stretchable and less slack than the thread material of threads oriented in the circumferential direction of the stencil, which consists of threads having a greater extension than in the direction of the stencil longitudinal axis. The threads are made of thread materials with higher wear resistance, and the thread materials of the longitudinal threads include or consist of PET or PEN.

Description

technical field [0001] The invention relates to a fabric for the production of stencils for rotary screen printing, having interdigitated filaments of plastics filaments, which is coated with an emulsion, which is especially photosensitive. The invention also includes a stencil made therefrom, and the use of the stencil. Background technique [0002] Centuries after its first use in China, the screen printing process has been known in Europe since about the 19th century; a fine mesh woven cloth or fabric, or wire mesh material, is stretched over a screen printing frame and printed by A stencil covers an image-free area so that it cannot be penetrated by ink. In addition to hand-engraved stencils - such as marking or writing - photolithographically produced direct or indirect stencils are now preferred; the choice of the kind of stencil used - in the case of direct stencils, the stencil has an emulsion, has a direct film and an emulsion, or With direct film and water - depe...
