Embodiment 1
[0040] Raw materials: DSC-14 starch 120kg, PVA 10kg, LMA-95 synthetic slurry 25kg, emulsified oil 16kg, smoothing agent 3kg.
[0041] Process: In the normal pressure mixing tank, first put 75% of the total amount of water, put in PVA, then put in DSC-14 starch, LMA-95 synthetic slurry, emulsified oil and smoothing agent in turn, stir at high speed for 5 minutes, turn on Steam until the pot boils, when the temperature reaches 95°C, boil the slurry for 20 minutes, add water to make up the volume, and the solid content of the slurry is 15.0%.
Embodiment 2
[0043] The sizing process is carried out in accordance with the following procedures: warp creel→water washing tank→multi-tank dyeing→water washing tank→high-pressure press equipment→sizing tank→drying room→car head→weaving shaft; among them, the sizing speed: 30m / min; Tank temperature: above 95°C.
