摘　　要：以L-谷氨酸钠为原料,采用干热法合成天然保湿因子成分L-吡咯烷酮羧酸钠(PCA-Na),探讨了合成工艺条件对转化率的影响;热解温度190℃,热解时间90min条件下,L-谷氨酸钠的转化率可达到96%以上,产物的吸湿、保湿性能优于甘油和丙二醇.由该保湿因子制备的涤棉(T/C)混纺整理织物的吸湿、透湿等舒适性能指标得到显著改善.The natural moisturizing factor component sodium L-pyrrolidonecarboxylate （PCA-Na） was synthesized from sodium L-glutamate by dry heating method. The influence of the synthetic conditions on the transition ratio was investigated. The sodium L-glutamate transition ratio attained more than 96% with pyrolysis at 190 ℃ for 90 min. The hydroscopic and moisture retaining properties were better than glycerin and propylene glycol. The T/C blends finished with this moisturizing factor component showed remarkably improved comfortableness indices such as hydroscopic and moisture retaining properties.
