Embodiment 1
[0007] Embodiment 1: ultra-high-viscosity refined cotton production process, its specific production process is as follows: a, material selection, cotton opening: select 4 tons of high-quality cotton linters without three silk impurities as raw material, and the fiber length of cotton linters is between 13 ~ 15mm, absolute dryness is 92%, maturity is over 80%, and has been treated with loosening, impurity removal and cotton opening; The final cotton linters are sprayed with a dissolving ratio of 1:2.7. After extrusion treatment at 0.18MPa, the sodium hydroxide solution is fully and evenly penetrated into the cotton linters to form alkali fibers, and the humidity of the alkali fibers is controlled at 78%; c , Pretreatment: The alkali fibers after soaking in alkali fully and uniformly are subjected to 2MPa rolling treatment, and the lye solution rolled out is recycled and reused. After rolling, the humidity of the alkali fibers is controlled at 45%, and then the mass concentratio...
Embodiment 2
[0008] Embodiment 2: ultra-high-viscosity refined cotton production process, its specific production process is as follows: a, material selection, cotton opening: select 4 tons of high-quality cotton linters without three silk impurities as raw material, and the fiber length of cotton linters is between 13 ~ 15mm, absolute dryness is 92%, maturity is over 80%, and has been treated with loosening, impurity removal and cotton opening; The final cotton linters are sprayed with a solvent ratio of 1:3.0, and after extrusion treatment at 0.20 MPa, the sodium hydroxide solution is fully and evenly penetrated into the cotton linters to form alkali fibers, and the humidity of the alkali fibers is controlled at 75%; c , pretreatment: the alkali fiber after soaking in alkali fully and evenly is processed through 3MPa rolling, and the lye liquid that is rolled out is recycled and reused. 4 kg of AES auxiliary agent is used to perform three times of repeated spraying and rolling treatment ...
Embodiment 3
[0009]Embodiment 3: ultra-high-viscosity refined cotton production process, its specific production process is as follows: a, material selection, cotton opening: select 4 tons of high-quality cotton linters without three silk impurities as raw material, and the fiber length of cotton linters is between 13 ~ 15mm, absolute dryness is 92%, maturity is over 80%, and has been treated with loosening, impurity removal and cotton opening; The final cotton linters are sprayed with a solvent ratio of 1:2.8, and after extrusion treatment at 0.19MPa, the sodium hydroxide solution is fully and evenly penetrated into the cotton linters to form alkali fibers, and the humidity of the alkali fibers is controlled at 76%; c , Pretreatment: The alkali fibers after soaking in alkali fully and evenly are subjected to 2.8MPa rolling treatment, and the lye solution rolled out is recycled and reused. After rolling, the humidity of the alkali fibers is controlled between 43%, and then the mass concentr...
