Abstract
The invention relates to a production process of ultrafine denier yarns, which is characterized by including the following steps: 1) feeding raw materials to a screw extruder through a material inlet; 2) extruding the raw materials through the screw extruder; 3) feeding the raw materials extruded by the screw extruder to a melt dispensing tube to keep warm; 4) metering the raw materials through a metering pump after the raw materials are dispensed by the melt dispensing tube, producing yarns by a spinning component and keeping side blowing during producing yarns; 5) feeding the yarns to a first roll and a second roll through a shaft after applying 1% to 1.5% of oil to the yarns by side blowing; 6) feeding the yarns to a third roll and a fourth roll after passing the first roll and the second roll; 7) feeding the yarns to a fifth roll through the network after passing the third roll and the fourth roll; 8) winding the yarns on a finished-product rotary shaft to be a spindle by the rotation speed ranging from 4800m/min to 4900m/min after the yarns pass the fifth roll. By the production process, ultrafine denier yarns with 0.51dpf can be produced effectively, have performance superior to that of conventional products and accordingly have wide market prospects.
