Embodiment Construction
[0015] Below in conjunction with embodiment the present invention will be further described.
[0016] Example: a production method of grinding and polishing fiber filaments blended with PET and SIC.
[0017] The first step: Mix the PFT bottle flakes and PET filaments evenly, and dry them under vacuum at 140 degrees Celsius;
[0018] Step 2: Keep the temperature at 140 degrees Celsius, add 0.1% calcium stearate under normal pressure, and mix well;
[0019] The third step: add 10% silicon carbide micropowder of the total mass of the above-mentioned materials, and mix evenly;
[0020] The fourth step: the mixture is melted and extruded by a screw, and then spun through a spinneret and wound to obtain a spun filament;
[0021] Step 5: After balancing, stretch, curl, relax and heat-set to obtain polished fiber filaments.
[0022] The above-mentioned SIC silicon carbide powder number is 2000#, the melt temperature of melt extrusion is 280 degrees Celsius, the melt viscosity is 0....
