Example Embodiment
[0019] [Example 1]
[0020] Remove the spinneret from the spinning assembly of wet spinning, immerse the spinneret saturated with the spinning solution in a solution containing 95% dimethyl sulfoxide by mass for 3 minutes, take out the spinneret, The spinning solution solidified on both sides is torn off; then the spinneret is put into a container containing dimethyl sulfoxide, and the container is cleaned in an ultrasonic water bath with heating function. The ultrasonic frequency is 130KHz, and the cleaning is performed 3 times. The cleaning temperature is 60℃ each time for 5 minutes; then the spinneret is dried in a blast oven at a drying temperature of 95℃, and the drying time is 3 minutes; finally, it is made of stainless steel sintered material with a filtration precision of 10μm The compressed air filtered by the resulting filter element is blown toward the outer surface of the spinneret for 3 minutes. Complete the cleaning process of the spinneret. The total cleaning tim...
