摘要
利用超声波对处在蒸馏水的棉纤维进行处理，观察、测试计算棉纤维的微观形貌与聚合度、分子量与断裂强力。研究表明，棉纤维经过在蒸馏水静止侵泡、在蒸馏水中经超声波处理后，其天然转曲的扭曲率均呈现下降趋势，而纤维直径、反光强度增加。其后在蒸馏水静止侵泡处理的棉纤维，其聚合度、分子量与断裂强力变化不大，而经超声波处理后的棉纤维均有较大幅度的降低。
Micro-morphology, degree of polymerization,molecular weight and mechanical properties change were tested to study the changes of cotton fiber caused by uhrasonic treatment in distilled water. The research shows that ＂alter the experiments processing,the natural cotton fiber twist rate in still distilled water and ultrasonic treatment water was both decreased,however,the fiber＇ diameter, reflective intensity of the fiber were increased. After the 2 ways of treatment,breaking strength has increased slightly at point of 0.5 hour. By treatment in distilled water, the degree of fiber aggregation,molecular weight and tensile strength changed little, while properties of cotton fiber decreased greatly after ultrasonic treatment.
