Hydrophobic and oileophobic finishing agent and preparation method thereof

The invention discloses a hydrophobic and oileophobic finishing agent and a preparation method thereof. The method comprises the steps that 0.1-3 parts of fluorine-containing emulsion is added into 0-100 parts of water, after the mixture is stirred uniformly, 0-3 parts of a surfactant is added, after the mixture is stirred fully, 0-3 parts of cross-linking monomers are added, and after mixed liquid is stirred uniformly, acid is added to adjust a pH value to range from 4 to 6, so that the hydrophobic and oileophobic finishing agent is obtained. The hydrophobic and oileophobic finishing agent has excellent washing resistant performance, and can be applied to various textile materials such as cotton, dacron, nylon, real silk and polyester. In addition, the preparation method has the remarkable advantages of being low in investment, easy to operate, wide in prospect and the like.
