用超声波对棉织物进行纳米整理的研究

Study of Nano-finishing on Cotton Fabric with Ultrasonic

为了对超声波整理纳米纺织品工艺作出理论解释及试验研究,从微粒在超声波场中的受力运动情况进行分析,对超声波整理纳米织物的机理做出了解释;以多孔材料模拟纺织品,对超声波增强嵌入的影响因素进行了研究;通过扫描电镜对超声波整理后纳米材料在棉织物中的分布状态进行了观察。结果证明:超声波场中的主声辐射力可使纳米粒子在纺织品中聚集且与纤维表面结合;纳米材料嵌入量受纳米分散液浓度、超声作用频率和时间以及织物距超声换能器的距离影响;经该工艺整理的棉织物其整理效果能经受住多次水洗。

To explain and research finishing processing of nano-textile with ultrasonic in theory, stress and movement of particles in ultrasonic field were analysed and the finishing principle was explained. Textile was simulated by porous materials, influential factors of nano-particles into porous materials by ultrasonic was studied. The distribution of nano-particles finished by ultrasonic in cotton field was observed by SEM. The result proves that in ultrasonic field primary acoustic radiation force could make nano-particles assembled and combined with surface of fibre in textile. The embedding mass is effected by concentration of nano-dispersing solution, frequency and acting time of ultrasonic, distance between fabric and ultrasonic transducer. Cotton fabric finished by processing mentioned above can afford repeated washing.
