PURPOSE:To facilitate penetration of a photosensitive resin to enhance an adhesion, by a method wherein; after a specific polyester monofilament is woven into a screen, a treatment for loss in weight is conducted with a solvent to apply emboss patterns on the surface of the fiber cloth. CONSTITUTION:A monofilament, containing fine particles in a polyester having ethylene terephthalate units 80mol% ore more, is woven into a screen, thereafter being treated to reduce the weight with a solvent capable of dissolving or decomposing the polyester such as caustic soda water solution, whereby the fine particles and the polymer around the fine particles are removed as much as possible to generate sophisticated emboss patterns on the surface of the fiber. In this manner, the increase of the surface area and the penetration of a photosensitive resin into the sophisticated emboss patterns are realized, thus enabling improvement of an adhesion. The fine particles of, for example, mica, talc, kaolin, glass powder, zirconium silicate, titanium oxide, calcium carbonate, and silica, can be used here; especially the calcium carbonate and silica are preferable. |
