摘　　要：纱线的吸湿透湿性能是影响纺织品舒适性的基本条件和重要因素。测试大麻、棉、棉/大麻和棉/大麻/莫代尔这4种纱线在不同温湿度条件下的吸放湿性能。结果表明:大麻纱线的毛效数值最高,可达11.0 cm,说明大麻纱线具有很好的吸湿性能;同一温湿度条件下,当纱线吸湿达到平衡时,大麻、棉和棉/大麻混纺纱线的回潮率接近,棉/大麻/莫代尔混纺纱线的回潮率明显比前3种纱线高;棉/大麻/莫代尔混纺纱线的吸放湿速率最大,吸放湿速率减小的最快;大麻纱线的吸放湿速率比棉、棉/大麻混纺纱线快。The moisture absorption and moisture permeability of the yarn are important factors influencing the fabric comfort.The moisture absorption and moisture permeability properties of hemp,cotton,hemp/cotton and hemp/cotton/modal were investigated under different temperature and relative humidity.The results showed that the capillary effect of the hemp was the best,up to（11.0 cm）,indicating the hemp yarn had good moisture absorption.Under the same temperature and humidity,when the moisture absorption reached balance,the regain percentage of cotton/hemp/modal blended yarn was higher than the other three yarns whose regain percentage was close.Meanwhile,the moisture absorption and permeability speed of cotton/hemp/modal blended yarn was the fastest,and its diminishing speed of moisture absorption and permeability was also the fastest.The moisture absorption and permeability of hemp yarn were better than those of cotton and cotton/hemp.
