摘　　要：采用光学法测量了不同材质单根纤维的接触角,并对测量单根纤维接触角的影响因素进行分析。结果表明:不同的纤维制备方法制取的纤维接触角不同,其中,硝酸-氯酸钾离析的纤维接触角与次氯酸钠和过氧化氢-冰醋酸离析的纤维接触角差异比较显著。同一处理方式得到的不同纤维的接触角不同,苎麻纤维接触角最小。对于单根天然植物纤维,环境的温、湿度都会影响其接触角,湿度的影响更明显;对于单根再生纤维素纤维,温度对接触角几乎没有影响,湿度的影响较大;对于单根化学合成纤维,环境的温、湿度对其影响较小,湿度几乎没有影响。The objective of this research was to investigate the influence factors of testing contact angle of single fibers by using optical methods.The results indicated that the contact angles of fibers isolated by different methods were different,and the contact angle of fibers isolated in HNO3-KClO3 was different significantly with that isolated in NaClO and H2O2-HAc.With the same treatment,the fibers＇ contact angle of different types was various,the smallest one was ramie fibers.Both temperature and relative humidity affected the contact angle of natural fibers,and humidity influenced more.Temperature affected contact angle of regenerated cellulose fibers scarcely,but humidity influenced significantly,however,temperature affected that of synthetic fibers little and humidity almost had no influence on it.
