Modification of the Flax Fiber with Acetylation

摘要

The effect of acetylation modifying pretreatment of the flax fiber properties was researched. By the acetylation, the property and spinning ability of flax technical fiber have been largely improved. It can be used in cotton system processing to develop superior quality and diversified flax products. In this paper, it uses the orthogonal experiment to modify the flax fiber with acetylating. Through testing the physical mechanical properties of the flax fiber, the influences of the modified condition, such as the caustic soda density, infusion time, acetate density and acetylating time are optimized. So that the fiber can be modified to improve spinning performance to meet high-production high-end linen and meet the requirements of thin fabric.
