After the polyurethane fiber cloth is soaked in hot water for 10 hours, the sterilization efficiency is reduced by 7.4 percent when the polyurethane fiber cloth is installed in a mask again.
Example 5
The mask is the same as example 2 in specific structure and implementation manner, and is different in that succinic acid is 0.5 parts by weight in the preparation process of the pretreatment liquid.
After the polyurethane fiber cloth is soaked in hot water for 10 hours, the sterilization efficiency is reduced by 8.7 percent when the polyurethane fiber cloth is installed in a mask again.
Example 6
The mask is the same as example 2 in specific structure and implementation manner, and is different in that succinic acid is 5 parts by weight in the preparation process of the pretreatment liquid.
After the polyurethane fiber cloth is soaked in hot water for 10 hours, the sterilization efficiency is reduced by 4.4 percent when the polyurethane fiber cloth is installed in a mask again.
The mask loads titanium dioxide on polyurethane fibers through polyurethane emulsion, particularly succinic acid is added, the dispersion uniformity and firmness of the titanium dioxide are improved, free radicals are generated through photocatalysis under the action of the LED lamp, and the free radicals and water vapor are cooperated to degrade organic matters in inhaled gas and kill bacteria and viruses. And the breathing permeability is good, the wearing feeling is comfortable, the repeated use can be realized, and the high sterilization effect can be still kept after multiple times of washing.
The above is only a preferred embodiment of the present invention, and the protection scope of the present invention is not limited to the above-mentioned embodiments, and all technical solutions belonging to the idea of the present invention belong to the protection scope of the present invention. It should be noted that modifications and embellishments within the scope of the invention may be made by those skilled in the art without departing from the principle of the invention.
