DULL POLYAMIDE 56 FIBER AND METHOD FOR MANUFACTURING THE SAME

摘要

A method for manufacturing a dull polyamide 56 fiber includes steps as follows. Bright polyamide 56 chips are provided. A viscosity adjusting step is provided, wherein a relative viscosity in sulfuric acid of the bright polyamide 56 chips is adjusted to a range of 2.90 to 3.00. A moisture adjusting step is provided, wherein a moisture content of the bright polyamide 56 chips is adjusted to a range of 350 to 550 ppm. A spinning step is provided, which includes providing dull polyamide 6 chips and a blending step. The dull polyamide 6 chips include TiO2. In the blending step, the dull polyamide 6 chips and the bright polyamide 56 chips dealt with the viscosity adjusting step and the moisture adjusting step are melted and blended, and then spun at a temperature ranging from 275° C. to 285° C., thus the dull polyamide 56 fiber is obtained.
