PURPOSE:To reduce the occurrence of white-powder scum to enable a monofilament to be woven with a fine denier and a high strength, by a method wherein a monofilament is made of a polyester containing a calcium compound as fine particles with specific fineness and breaking strength. CONSTITUTION:A monofilament made of a polyester containing a calcium compound as fine particles has a fineness of 5-20 denier and a breaking strength of 5.0-8.0 g/D. The calcium compound is preferably selected from among groups of calcium carbonate, calcium oxide, and calcium terephthalate. The fine particles made of the aforesaid calcium compound reduce a coefficient of friction between the monofilament and a metal to prevent the monofilament itself from being scraped off. Because the particles are soft, the scraping-off of the monofilament caused by the friction of a reed can be prevented. The monofilament has a single-yarn fineness of 5-20 denier, and with more than 20 denier the possibility of enhancing an opening area is eliminated in a high- mesh screening gauze. On the other hand, a breaking strength of 5.0-8.0 g/D is preferable, and with more than 8.0 g/D the occurrence of white-powder scum is increased.
