preparation example Construction
[0074] The preparation process of the auxiliary agent can be: mixing the polytetrafluoroethylene emulsion and the benzyl silicone oil emulsion to make a mixed liquid 1, and mixing the water-based flexible polyacrylate emulsion and the amino modified polyether silicone oil to make the mixed liquid 2 , The mixed solution 1, the mixed solution 2, the silane coupling agent and the absolute ethanol are mixed uniformly, added to the water in which a proper amount of ammonium silicofluoride is dissolved, and the auxiliary agent is made after being fully dissolved.
[0075] The auxiliary agent is impregnated according to the amount of o.w.f 1.9% to 4.7%, the liquid ratio of 1:10 to 1:15, and the temperature of 60°C to 90°C for 23 to 36 minutes, then take it out, dehydrate and dry. The fabric can also be finished according to actual needs according to the process conditions in the prior art.
[0076] For example, the following additives can be used for finishing:
Embodiment 1
[0078] PTFE emulsion 18Kg Benzyl silicone oil emulsion 14.5Kg Amino modified polyether silicone oil 4.1Kg Water-based flexible polyacrylate emulsion 12Kg A silane coupling agent 0.5Kg Ammonium silicofluoride 0.19Kg Absolute ethanol 1.8Kg water 48.91Kg
Embodiment 2
[0080] PTFE emulsion 22Kg Benzyl silicone oil emulsion 13Kg Amino modified polyether silicone oil 4.7Kg Water-based flexible polyacrylate emulsion 19Kg A silane coupling agent 1.4Kg Ammonium silicofluoride 0.26Kg Absolute ethanol 0.7Kg water 38.94Kg
