摘要： A core-sheath composite type polyester monofilament for use in a screen gauze in which the sheath ingredient is a polyester formed by adding and copolymerizing, based on the polyester, 2 to 10% by weight of a polyalkylene oxide with a coloration degree (APHA) after heating at 175° C. for one hour of 30 or less and having a number average molecular weight of from 300 to 4000 and having a peak temperature (Tmax) of a dynamic loss tan (tan &dgr;), at a measuring frequency of 110 Hz of from 97 to 120° C. which is lower by 10° C. or more than that for the core and the area ratio of core to sheath is within a range from 60:40 to 90:10. The polyester monofilament for use in a screen gauze is a monofilament for use in the high mesh screen gauze capable of completely preventing formation of scams during weaving, satisfactory in the gauze tension and excellent in the dimensional stability of gauze and in the adhesion to the photosensitive resin.

摘要： 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.
