Zusammenfassung: | PROBLEM TO BE SOLVED: To provide polybutylene terephthalate resin monofilament that has reduced filament breakage in the production line with the production efficiency increased and has improved quality because of increased uniformity in strength and thickness, when the polybutylene terephthalate resin monofilament is produced from the polymer formed through the continuous polymerization process. SOLUTION: The monofilament is produced by using the polybutylene terephthalate resin obtained through the continuous polymerization process and has =20 μm sizes in the film thickness of 50 μm. |
