5. The degumming process for a fibrilia according to claim 4, wherein: in step S 200 Wherein the pre-degumming liquid medicine comprises ethanol, water and sulfuric acid, the volume fraction of the ethanol is 60-98%, and the concentration of the sulfuric acid is 0.4-0.8g/L.
6. The degumming process for a fibrilia according to claim 4, wherein: in step S 300 In the middle feeding process, the yarn cage rotates continuously at the speed of 3-5 revolutions per minute, and the compression bar moves up and down to compact and homogenize fibrilia; and meanwhile, continuously spraying water into the yarn cage from top to bottom for leaching, wherein the leaching water temperature is 50-80 ℃.
7. The degumming process for a fibrilia according to claim 4, wherein: in step S 500 The emulsion is prepared from (by weight) mechanical oil 6-30 g, sodium hydroxide or potassium hydroxide 2-10 g, detergent 2-12 g and water 3-12 kg.
8. The process for degumming a fibrilia according to claim 4, whereinThe method comprises the following steps: in step S 100 Wherein the weight ratio of the fibrilia to the treatment fluid is 1:10-30, the concentration of sodium hydroxide is 3-6 g/L, the temperature is 60-80 ℃, the treatment time is 5-20 min, and the pH value is neutral by water washing.
9. The degumming process for a fibrilia according to claim 4, wherein: in step S 200 Wherein the weight ratio of the fibrilia to the treatment liquid is 1:10-30, the pH value is 4-6, the concentration of anhydrous ferrous sulfate is 8-10 g/L, the concentration of hydrogen peroxide is 7-10 g/L, the treatment temperature is 50-80 ℃, the treatment time is 30-60 min, and the pH value is neutral by washing with water.
10. The degumming process for a fibrilia according to claim 4, wherein: the fibrilia is hemp, flax, ramie, kendir, jute, sisal or kenaf.
