The Function of Water Absorption and Purification of Lotus Fiber

Abstract

In order to understand the water absorption and purification performance of lotus fiber, the relationship between the structure of lotus fiber and water absorption and purification performance was analyzed through experimental tests. Under standard conditions, the characteristics of the absorption and desorption characteristics of lotus fiber were determined, and from this, the regression equations of moisture regain and time and the equations of the rate of moisture absorption and desorption of lotus fiber during the process of reaching equilibrium between absorption and desorption were deduced.The results showed that the lotus fiber had better absorption and desorption properties, and the resorption and desorption rates of lotus fiber were higher than those of cotton fiber and flax fiber.The moisture absorption rate of lotus fiber is the highest, the flax is centered, and the cotton fiber is the lowest;The water absorption and purification performances of the three fibers were similar, and the lotus fiber was slightly higher than the cotton fiber and the flax fiber.
