Embodiment 1
[0021] A production method of functional filament, it comprises the following steps:
[0022] (1) By weight, weigh 39% of PET slices and 40% of PEE slices for pre-crystallization and drying; by weight, weigh 6% of anti-radiation masterbatch and 8% of drug-loaded microspheres for drying, and weigh 6% % of the crystallization accelerator, weighed 1% of the electrical stress particles;
[0023] (2) Mix the dried polymer chips and the dried anti-radiation masterbatch with the drug-loaded microspheres, and then use a screw extruder to form a mixed spinning melt;
[0024] (3) After the mixed spinning melt is filtered and pressurized, it is distributed to each spinneret assembly by a metering pump to produce primary fibers;
[0025] (4) blowing and cooling the as-spun fibers in the spinning tunnel, the spinning tunnel is divided into upper and lower parts, the upper part of the spinning tunnel is blown with alkaline cooling air, and the lower part of the spinning tunnel is blown wit...
Embodiment 2
[0033] A production method of functional filament, it comprises the following steps:
[0034] (1) By weight, weigh 35% of PBT slices and 40% of PTT slices for pre-crystallization and drying; by weight, weigh 7% of anti-radiation masterbatch and 8% of drug-loaded microspheres for drying, and weigh 7% % of the crystallization accelerator, weighed 3% of the electrical stress particles;
[0035] (2) Mix the dried polymer chips and the dried anti-radiation masterbatch with the drug-loaded microspheres, and then use a screw extruder to form a mixed spinning melt;
[0036] (3) After the mixed spinning melt is filtered and pressurized, it is distributed to each spinneret assembly by a metering pump to produce primary fibers;
[0037] (4) blowing and cooling the as-spun fibers in the spinning tunnel, the spinning tunnel is divided into upper and lower parts, the upper part of the spinning tunnel is blown with alkaline cooling air, and the lower part of the spinning tunnel is blown wit...
