Embodiment 1
[0044] A novel spinneret washing process is characterized in that: the specific steps are as follows:
[0045] The first step, lye spray washing;
[0046] The second step, hot water spray washing;
[0047] The third step, hot water spray washing;
[0048] The fourth step; cut water;
[0049] The fifth step, pickling;
[0050] The sixth step, lye spray washing;
[0051] The seventh step, hot water spray washing;
[0052] The eighth step, hot water spray washing;
[0053] The ninth step, cut the water;
[0054] The tenth step, drying.
[0055] The lye spraying in the first step and the sixth step is to continuously clean the spinneret after the lye is filtered, the spraying pressure is 1.2-1.7kgf, the working temperature is 40-50°C, and the filtration is 80-120 filter.
[0056] The hot water spray washing in the second and seventh steps is specific, and the spinneret is cleaned continuously after the city water is filtered. The spray washing pressure is 1.2-1.7kgf, the ...
Embodiment 2
[0062] The first step is lye spraying; after the lye is filtered, the spinneret is continuously cleaned, the spraying pressure is 1.5kgf, the working temperature is 40-50°C, and the filtration is specifically 100 mesh filtration.
[0063] The second step is hot water spray washing; after the city water is filtered, the spinneret is continuously cleaned, the spray washing pressure is 1.5kgf, the working temperature is 50-60°C, and the filtration is specifically 100 mesh filtration.
[0064] The third step is hot water spray washing; after the city water is filtered, the spinneret is continuously cleaned, the spray washing pressure is 1.5kgf, the working temperature is 50-60°C, and the filtration is specifically 50μ filtration.
[0065] The fourth step: cut water; under normal temperature, use air to spray the spinneret continuously, and the spray pressure is 3523Pa.
[0066] The fifth step, pickling; at room temperature, use concentrated H 2 SO 4 The solution washes the spinn...
