[0017] In a specific embodiment, the weight ratio of the ethanol added twice is 23:1; the weight ratio of the monomer added twice is 1:3; and the weight ratio of the initiator added twice is 9:1.

[0018] By adopting the above technical solution, the addition of ethanol, monomer and initiator is further limited to two times, so that the slurry can be better formed.

After the heat preservation reaction, add ammonia water, stir and mix evenly, then add deionized water at 75°C, stir and mix evenly, finally add emulsifier, penetrant, defoamer, and lubricant, stir for 25-35 minutes, adjust the viscosity and sugar content of the slurry, so that the viscosity of the slurry is lower than 100 mPa·s and the sugar content is 19.5-20.5 g / ml, and obtain textile slurry.

9. The method for preparing a textile slurry for ultra-fine yarn according to claim 8, characterized in that: The weight ratio of the ethanol added twice is 23:1; the weight ratio of the monomer added twice is 1:3; and the weight ratio of the initiator added twice is 9:1.
