[0020] The present invention will be further described below in conjunction with the examples.
[0021] A deepening finishing method of wool fabric, the method at least comprises the following steps:
[0022] (1) Preparation of fluoroalkyl modified amino silicone oil:
[0023] 3L of toluene was added to the reaction vessel, and 3KG of N-β-aminoethyl-γ-aminopropyl methyl silicone oil and 3.2KG of hexafluorobutyl acrylate were added in sequence under nitrogen protection; solvent to obtain fluoroalkyl modified amino silicone oil, the mass fraction of fluorine is 25%;
[0024] (2) Emulsification of fluoroalkyl modified amino silicone oil:
[0025] Add 1KG fluoroalkyl modified amino silicone oil to the high-speed shearing dispersing emulsifier, then add 0.15KG fatty alcohol polyoxyethylene ether surfactant, stir and emulsify at room temperature at 2800 r / min for 15 minutes, and dilute with water to obtain the mass concentration It is 30 g / L finishing liquid;
[0026] (3) Paddin...
