Study on the Chemical Agent Resistance Ability of Bamboo Pulp Fibers

Abstract

This paper aims to understand the chemical properties of bamboo pulp fiber, and to provide a theoretical basis for developing bamboo pulp fiber fabric. The chemical agent resistance ability of bamboo pulp fiber is therefore researched through analyzing and comparing the dissolution of the fiber at different concentrations and different temperatures of the chemical reagents. The results show that different concentrations of acid and alkali, oxidizing agents, and reducing agents affected the solubility of viscose and bamboo pulp fibers. Under a high concentration of acid and alkali, oxidant, or reducer solution, viscose and bamboo pulp fibers were easily dissolved. The solubility of viscose and bamboo pulp fiber decreased with a reduction in the concentration of the chemical reagent. The resistance of bamboo pulp fiber to strong acid is as poor as that of viscose fiber. However, the resistance of bamboo pulp fiber to weak acid is better than that of viscose fiber. The effects of acid on bamboo pulp fiber vary according to the type of acid, its concentration and the temperature it is at. The alkali resistance and oxidation resistance of bamboo pulp fiber is as high as that of viscose fiber, but bamboo pulp fiber is more resistant to reducing agents than viscose is.
