摘要
以水溶性阿拉伯树胶作为对比,研究了棉织物上蓖麻油、磷脂、液体石蜡、羊毛脂的脱附过程。用准二级动力学方程拟合了脱附动力学,相关系数均接近于1。结果表明:阿拉伯树胶在洗衣液中的脱附效果最好,脱附得最快,羊毛脂最难脱附,但是脱附速率较快。通过SEM表面观察发现,洗涤后阿拉伯树胶在纤维上几乎没有残留;羊毛脂洗涤前后变化不大,蓖麻油不易吸附也不易清除;磷脂、液体石蜡、蓖麻油洗涤前后均有一定程度的残留,附着在纤维表面,不同污渍在棉纤维表面的结合力不同。
A comparative study was undertaken of desorption process of water soluble arabic gum,castor oil,phosphatide,liquid paraffin,lanolin from the cotton fabric under certain conditions.Quasi-secondary reaction kinetics equation was used to fit desorption curves,and the correlation coefficients were close to 1.The results showed that arabic gum exhibited the best desorption result and the fastest desorption rate in the washing water.On the contrary,lanolin was most difficult to be desorbed,but it had faster desorption rate than other soils.SEM observation showed that almost no arabic gum residue was on the fiber surface after washing;lanolin changed little before and after washing;castor oil was not easy to be adsorbed or easy to be removed;and phosphatide,liquid paraffin,castor oil all displayed certain degree of residues after washing,and were adhered to the fiber surface.Adhesion forces of different soilson the sunface of cotton fiber were different.
