[0018] First, plant ramie on a land of 5m×5m. In the initial stage of ramie growth, spray 100mg / L butyl titanate evenly on the leaves of ramie, and then water tap water 4 hours after spraying. Spray and water alternately for 15 days, and then change to Spray with 200mg / L butyl titanate, and then pour the carbon tetrachloride solution 4 hours after spraying, continuously alternately spray and water for 10 days, and finally spray with 300mg / L butyl titanate solution, and then use it after 4 hours Irrigate with propanol, continuously alternately spray and water for 8 days, so that the cultivated ramie contains titanic acid; pick 3 kg of the above-mentioned cultivated ramie, clean it with water, put it into the reaction tank, and add 3% cellulose of the total mass to the tank Enzyme, enzymatic hydrolysis for 3 hours, after enzymolysis, add 35% concentrated hydrochloric acid to the pool for acidification until the pH reaches 2, and filter after standing for 30 minutes to obtain a mu...

[0021]First, plant ramie on a land of 5m×5m. In the initial stage of ramie growth, spray 100mg / L butyl titanate evenly on the leaves of ramie, and then water tap water 6 hours after spraying. Spray and water alternately for 17 days, and then change to water Spray with 200mg / L butyl titanate, and then pour the carbon tetrachloride solution 6 hours after spraying, continuously alternately spray and water for 12 days, and finally spray with 300mg / L butyl titanate solution, and then use it after 6 hours Irrigate with propanol, continuously alternately spray and water for 9 days, so that the cultivated ramie contains titanic acid; pick 3.5kg of the above-mentioned cultivated ramie, wash it with water, put it into the reaction tank, and add 3.5% of the total mass of fiber to the tank. Sulfase, enzymolysis for 3.5h, after enzymolysis, add concentrated hydrochloric acid with a mass fraction of 37% to the pool for acidification until the pH reaches 2.5, and filter after standing for 35m...

[0024] First, plant ramie on a land of 5m×5m. In the initial stage of ramie growth, spray 100mg / L butyl titanate evenly on the leaves of ramie, and then water tap water 8 hours after spraying. Continuously alternate spraying and watering for 20 days, and then change to water. Spray with 200mg / L butyl titanate, and then pour carbon tetrachloride solution 8 hours after spraying, continuously alternately spray and water for 14 days, and finally spray with 300mg / L butyl titanate solution, and then use it after 8 hours Irrigate with propanol, spray continuously and alternately, and water for 10 days, so that the cultivated ramie contains titanic acid; pick 4 kg of the above-mentioned cultivated ramie, clean it with water, put it into the reaction tank, and add 4% cellulose in total mass to the tank Enzyme, enzymatic hydrolysis for 4 hours, after enzymatic hydrolysis, add 40% concentrated hydrochloric acid to the pool for acidification until the pH reaches 3, and filter after standin...
