Embodiment 1
[0064] Example 1 A method for preparing high-efficiency cool-feeling mildew-proof herbal cotton, specifically comprising the following steps:
[0065] 1. Pretreatment steps of cotton fiber:
[0066] 1. Put the cotton fiber after carding and removing impurities into the dyeing vat, add sodium hydroxide solution and natural active agent to make a bath liquid; The power is 25 kilowatts, and the speed of the bath liquid ejected from the cage core is 20 m / s; the temperature of the bath liquid is slowly raised to 65 °C at a speed of 2 °C / min, and kept for 50 minutes for later use;
[0067] The concentration of sodium hydroxide solution is 4%; the natural active agent is dodecyl dimethyl betaine; the addition of said dodecyl dimethyl betaine is 0.3% of the cotton fiber weight.
[0068] 2. After step 1 heat preservation, lower the temperature of the bath liquid to 20°C and then add hydrogen peroxide; the concentration of hydrogen peroxide is 2g / L, close the top cover of the tank, tur...

[0088] Example 2 A method for preparing high-efficiency cool-feeling mildew-proof herbal cotton, specifically comprising the following steps:
[0089] 1. Pretreatment steps of cotton fiber:
[0090] 1. Put the cotton fiber after carding and removing impurities into the dyeing vat, add sodium hydroxide solution and natural active agent to make a bath liquid; The power is 25 kilowatts, and the speed of the bath liquid ejected from the cage core is 21 m / s; the temperature of the bath liquid is slowly raised to 60 °C at a speed of 2 °C / min, and it is kept for 30 minutes for later use;
[0091] The concentration of sodium hydroxide solution is 5%; the natural active agent is dodecyl dimethyl betaine; the addition of said dodecyl dimethyl betaine is 0.3% of the cotton fiber weight.
[0092] 2. Cool down the temperature of the bath liquid in step 1 to 18°C and then add hydrogen peroxide; the concentration of hydrogen peroxide is 3g / L, close the top cover of the tank, turn on the p...

[0111] Example 3 A method for preparing high-efficiency cool-feeling mildew-proof herbal cotton, specifically comprising the following steps:
[0112] 1. Pretreatment steps of cotton fiber:
[0113] 1. Put the cotton fiber after carding and removing impurities into the dyeing vat, add sodium hydroxide solution and natural active agent to make a bath liquid; The power is 30 kilowatts, and the speed of the bath liquid ejected from the cage core is 22 m / s; the temperature of the bath liquid is slowly raised to 70 °C at a speed of 3 °C / min, and kept for 45 minutes for later use;
[0114] The concentration of the sodium hydroxide solution is 6%; the natural active agent is dodecyl dimethyl betaine; the addition of said dodecyl dimethyl betaine is 0.4% of the cotton fiber weight.
[0115] 2. Cool down the temperature of the bath liquid after the heat preservation in step 1 to 23°C, then add hydrogen peroxide; the concentration of hydrogen peroxide is 3g / L, close the top cover of th...
