Embodiment 1
[0036] A preparation method for deodorizing cellulose fibers, the specific process steps are as follows:
[0037] A. Cellulose Fiber Pretreatment
[0038] Take cellulose fiber as raw material, add it to the reaction kettle Ⅰ, and then take the sodium hydroxide solution with the ratio of cellulose fiber mass (kg): sodium hydroxide solution volume (L) as 1:10, and add it to the reaction kettle Then, the temperature in the reaction kettle I was raised to 90°C, and stirred for 1 hour; the mixed material was washed with soft water until neutral, and dehydrated to obtain the product I, which was set aside;
[0039] B. Copolymerization mixture preparation
[0040] Inject soft water at normal temperature into the reaction kettle II, and take 2-acrylamide-2-methan propanesulfonic acid and acrylic acid, and placed in the reaction kettle II, stirring at a constant speed until uniform, after 2-acrylamide-2-methylpropanesulfonic acid is dissolved, with 2-acrylamide-2-methylpropanesulfoni...
Embodiment 2
[0047] A preparation method for deodorizing cellulose fibers, comprising the steps of:
[0048] A. Cellulose Fiber Pretreatment
[0049] Use cellulose fiber as raw material, add it to reaction kettle Ⅰ, and add 4L of sodium hydroxide solution with a mass concentration of 0.5% per kilogram of raw material, raise the temperature in reaction kettle Ⅰ to 60°C, stir for 5 hours; then wash the mixture with soft water The material is neutral until it is dehydrated to obtain the product Ⅰ, which is set aside;
[0050] B. Copolymerization mixture preparation
[0051] Inject soft water at room temperature into reaction kettle II, add 2-acrylamide-2-methylpropanesulfonic acid, and add 0.8 L of acrylic acid per kilogram of 2-acrylamide-2-methylpropanesulfonic acid, stir at a constant speed until uniform, and wait until After 2-acrylamide-2-methylpropanesulfonic acid is dissolved, add 0.02kg of sodium dodecylsulfonate per kilogram of 2-acrylamide-2-methylpropanesulfonic acid, and stir un...
Embodiment 3
[0057] A preparation method for deodorizing cellulose fibers, comprising the steps of:
[0058] A. Cellulose Fiber Pretreatment
[0059] Use cellulose fiber as raw material, add it to the reaction kettle I, and add 20L of ammonia water with a mass concentration of 1.0% per kilogram of raw material, raise the temperature in the reaction kettle I to 100°C, stir for 0.5h; then wash the mixture with soft water to It was neutral and dehydrated to obtain product Ⅰ, which was set aside;
[0060] B. Copolymerization mixture preparation
[0061] Inject soft water at room temperature into reaction kettle II, add 2-acrylamide-2-methylpropanesulfonic acid, and add 1.3 L of acrylic acid per kilogram of 2-acrylamide-2-methylpropanesulfonic acid, stir at a constant speed until uniform, and wait After 2-acrylamide-2-methylpropanesulfonic acid is dissolved, add 0.20 kg of sodium dodecylsulfonate per kilogram of 2-acrylamide-2-methylpropanesulfonic acid, stir until completely dissolved, and o...
