摘　　要：本文探索了莱赛尔族纤维与其他再生纤维素纤维的化学溶解性能的细微差别,通过研究时间、温度和试剂配比等因素对溶解性能的影响,成功找出用经典方法——溶解法对再生纤维素纤维中的莱赛尔族纤维定性鉴别的方法,并对鉴别条件进行优化,最终确定在80∶10的甲酸/氯化锌溶液中,温度70℃、时间40 min,作为莱赛尔族纤维的定性鉴别条件。This paper probed into the subtle differences of chemical dissolving properties of Lyocell fibers and other regenerated cellulose fibers. By investigating the influence of time, temperature and reagent formula on dissolving properties, the classical method - the dissolution method was found out to be suitable tbr distinguishing Lyocell fibers from other regenerated cellulose fibers and the conditions were optimized. Finally, it determined that the best conditions for the qualitative identification is in a solution of tbrmic acid/zinc chloride （80 ： 10） at a temperature of 70 ℃ for a time period of 40 minutes.
