摘要

Lyocell fibers have excellent properties, but they show a distinct tendency to fibrillate with wetting and mechanical stress. Chemical modification by esterification of these fibers Could be a good means of solving this problem. A scanning electron microscopy analysis shows that treatment with polycarboxylic acids can effectively reduce the fibrillation tendency of lyocell fibers. A revised wet abrasion test method is used to measure fibrillation tendency. Wet abrasion time and mechanical property measurements reveal that fibers treated with 5-6% 1, 2, 3, 4-butanetetra-carboxylic acid or 13-14% polymaleic acid exhibit satisfactory fibrillation resistance and mechanical properties.
