Abstract
The invention discloses a production technology of chloride-ion-removed refined cotton. The technology comprises the steps of material selecting, alkali-oxygen steaming, continuous pulp washing, bleaching, dehydrating and bake-drying, and packaging. During the alkali-oxygen steaming process, NaOH, H2O2 solutions and O2 are added. During the bleaching process, NaOCL and H2O2 solutions are added. A high-molecular YY-01 auxiliary agent is added during the alkali-oxygen steaming process. An integrating agent is added during the bleaching process. In the dehydrating and bake-drying process, one-step washing is carried out by using deionized water. The deionized water is processed through an original water treatment device, and is further treated by using an ion-permeable membrane. With the technology provided by the invention, steaming time of cotton refining technology is shortened, energy consumption is low, and discharge amount is low. Wastewater is effectively utilized and is treated in time, such that environment pollution caused by traditional cotton refining technologies is reduced. Also, pulp yield, product concentrated-alkaline resistance, product high-temperature resistance, product oxidant resistance, product hard water resistance, and the like are effectively improved.
