| titleOfInvention | Machine sewing thread made of polyphenylene sulfide fiber and production thereof |
| abstract | PURPOSE: To obtain the subject machine sewing thread having excellent alkali resistance, heat-resistance and moist-heat resistance, by melting a linear polyphenylene sulfide and subjecting the molten polymer to spinning, drawing and heat-treatment under specific condition. n CONSTITUTION: A linear polyphenylene sulfide containing phenylene sulfide unit accounting for ≥85% of the recurring unit is melted, spun at spinneret temperature of 310-330°C and a spinning speed of ≤1,000m/min and then drawn and heat-treated to obtain a drawn yarn. Said drawn yarn is applied with a primary twist with a twist coefficient (K) of 3,000-12,000 and subjected to twist- setting treatment at ≥140°C. Plurality of the obtained multi-filament are doubled, applied with secondary twist with a coefficient K of 3,000-15,000 and subjected to twist-setting treatment at a temperature between 180°C and the melting point of the fiber to attain an untwisting torque (T) of ≤20T/m and obtain the objective machine sewing thread having a strength of 3.0g/de, silk factor of ≥18, dry-heat shrinkage of ≤8.0% (at 220°C) and a single fiber denier of 2-10. n COPYRIGHT: (C)1989,JPO&Japio |
