s1, adding 114-228g of ammonium persulfate into 1-2kg of industrial xylan, continuously stirring at 55-65 ℃ for reaction for 5-8 hours, cooling to room temperature, and centrifuging at a rotating speed of 7000-9000r/min for 4-6min to obtain a centrifugal solid;
S2, adding centrifugal solids into deionized water, carrying out ultrasonic treatment for 5-10min, centrifuging for 8-12min again at a rotating speed of 7000-9000r/min, dialyzing in water by using a dialysis membrane with a molecular weight cut-off value of 8000-14000 Da to thoroughly purify solid products, and centrifuging for 15-25min at a rotating speed of 1000-3000r/min to obtain oxidized xylan;
S3, adding 150-200g of xylan oxide into deionized water to obtain 5wt% of dispersion liquid, adding 50-100g of acetic anhydride, adding 3wt% of NaOH solution to adjust the pH to 8-9, stirring gently at the speed of 100r/min for 4-6h at the temperature of 35-45 ℃, and centrifugally washing for 3-5 times to obtain acetylated xylan;
S4, adding 80-160g of acetylated xylan and 50-100mg of sodium montmorillonite into 10-20L of water, and adding sodium citrate to adjust the pH to 7 to obtain the low-temperature lotion.
2. The open-felt wool scouring process according to claim 1, wherein the open-felt wool comprises at least one of wool, rabbit hair, goat hair.
3. The process for washing open felt according to claim 1, wherein in the step (7), the temperature of the third tank, the fourth tank and the fifth tank is 43-45 ℃.
