<P>PROBLEM TO BE SOLVED: To provide a polyester monofilament for screen gauze in which high strength and high modulus are maintained in a high strength single component monofilament that is easily scraped compared to a core-sheath monofilament and a scraping defect occurring when obtaining a screen gauze having improved printing durability and dimensional stability can be suppressed. <P>SOLUTION: A polyester monofilament for screen gauze is a single component polyester monofilament, and the difference between a degree of crystallinity at a fiber center and a degree of crystallinity at a position 1 μm from a fiber surface to the fiber center in any fiber cross section perpendicular to a fiber axis of the polyester monofilament is 4% or less. <P>COPYRIGHT: (C)2013,JPO&INPIT |
