MESH WOVEN FABRIC FOR PRINTING SCREEN

摘要

A mesh cloth is composed of a composite filament. The composite filament is composed of raw material having good adhesiveness with screen emulsion and resin as sheath and raw material having high dimensional stability and elastic recovery as core. When the cloth is employed in label-stripping process as a test piece of 5 cm in width, stress-strain curve is measured by providing gripping distance 20 cm, breaking elongation is 15-40 %, breaking strength is more than 25 kg. f. When elongation is more than 5 %, relation of strength Y (kg.f) and elongation X (%) are such that Y is at least (X + 1 ) X 5/3. Volume ratio of core and sheath in the composite film is 1:5 -3:1, pref. 1:2 - 2:1. Raw material of the core component in the composite filament is a polyester or polyolefin and raw material of the sheath component is aliphatic or aromatic polyamide e.g. nylon-6, or nylon-6,6.
