Mesh fabric for printing screen

Abstract

The mesh fabric is advantageously applicable for producing a printing screen. The mesh fabric consists essentially of conjugate monofilaments each having a core and a sheath. The sheath is formed of a material having high adhesive property to an emulsion and a resin used for making the screen. The core is formed of a material having high dimensional stability and elastic recovery property. The mesh fabric has a breaking elongation of from 15 to 40% and a breaking strength of not less than 25 kgf, and a correlation between the strength (kgf) and the elongation (%) in the elongation range of not less than 5%, in the stress-strain curve of the mesh fabric by the labelled strip method at the specimen width of 5 cm and the grip interval of 20 cm satisfying the following formula: Y.gtoreq.(X+1).times.5/3. The mesh fabric, which comprises such special sheath and core type conjugate filaments, is significantly improved in the dimensional stability and the adhesive property to resins. Production of a printing screen with high precision and workability is enabled. The mesh fabric, which has a relatively high strength and a corelation between the strength and the elongation in the special range as mentioned above, affords to produce a screen having small elongation at high tension and high printing stability.
