Embodiment 1
[0043] The dried polyester chips are heated and extruded to be melted with a screw, the temperature of the screw is 280° C., and the rotation speed is 100 rpm. The melt is sent to each spinning position of the spinning box, and is accurately metered and filtered by the metering pump, and then sprayed out from the spinneret. The diameter of the spinneret holes was 100 μm. After the thin stream of melt is sprayed out, it is cooled and solidified into filaments by the cooling air flow. There is one hole in the cross-section of the fiber, and the opening size of the hole on the fiber surface is 40-60 μm, that is, the feeding gap of the special-shaped hole of the spinneret is set at 40-60 μm. The silver ion antibacterial agent with an average particle size of 20-30 μm is used as a functional substance, and the spinning machine oil with a content of 10 wt % of the functional substance is prepared after being dispersed by ultrasonic vibration. After the solidified filaments are wet...
Embodiment 2
[0049] The dried polyester chips are heated and extruded to be melted with a screw, the temperature of the screw is 280° C., and the rotation speed is 100 rpm. The melt is sent to each spinning position of the spinning box, and is accurately metered and filtered by the metering pump, and then sprayed out from the spinneret. The diameter of the spinneret holes was 100 μm. After the thin stream of melt is sprayed out, it is cooled and solidified into filaments by the cooling air flow. There are 3 holes in the cross-section of the fiber, and the opening size of the holes on the fiber surface is 20-30 μm, that is, the feeding gap of the special-shaped hole of the spinneret is set at 20-30 μm. Use TiO with an average particle size of 10-15 μm 2 Anti-virus and deodorizing functional substances are dispersed by ultrasonic vibration to prepare spinning machine oil with a content of 10wt% functional substances. After the solidified thread passes through an oil bath, the fiber stays ...
Embodiment 3
[0055] The dried polyester chips are heated and extruded to be melted with a screw, the temperature of the screw is 280° C., and the rotation speed is 100 rpm. The melt is sent to each spinning position of the spinning box, and is accurately metered and filtered by the metering pump, and then sprayed out from the spinneret. The diameter of the spinneret holes was 150 μm. After the thin stream of melt is sprayed out, it is cooled and solidified into filaments by the cooling air flow. There are 2 holes in the cross-section of the fiber, and the opening size of the holes on the fiber surface is 30-50 μm, that is, the feeding gap of the special-shaped hole of the spinneret is set at 30-50 μm. The tourmaline negative ion powder with an average particle size of 15-20 μm is used as a functional substance, and the spinning machine oil with a content of 12 wt % of the functional substance is prepared after surface modification and dispersion. When spinning filaments, the filaments ar...
