电雾化处理对羊毛织物抗起毛起球性能的影响

针对羊毛织物在穿着时受外力摩擦作用易起毛起球的现象,采用可产生单分散小尺寸微粒的电雾化技术整理羊毛织物。实验选用常见的环保型整理剂过氧化氢和壳聚糖溶液,探究整理剂类型、溶液浓度和处理时间对羊毛织物抗起毛起球性能的影响,并通过扫描电子显微镜观察电雾化整理前后羊毛织物和纤维表面的形貌变化。结果表明:电雾化处理壳聚糖溶液产生的微粒对羊毛纤维表面起到了包裹作用,羊毛织物抗起毛起球等级最高提升1级以上;电雾化处理过氧化氢溶液对羊毛纤维表面鳞片有一定的破坏作用,羊毛织物抗起毛起球等级可提升0.5级以上;电雾化处理过氧化氢和壳聚糖溶液对羊毛织物协同整理较长时间(如240 min),织物的抗起毛起球提升效果最好。

Effect of electro-spraying treatment on anti-pilling performance of wool fabrics

Wool fabrics are prone to fuzzing and pilling when they are worn by external forces. To deal with this problem, the electro-spraying technique capable of producing monodisperse micro liquid particles was used to treat wool fabrics. Commonly used finishing agents hydrogen peroxide and chitosan solution were employed in the experiments to explore the effects of finishing agent type, solution concentration and treatment time on anti-pilling performance of wool fabrics, and the morphological changes of the wool fabrics and fiber surfaces after electro-atomization finishing were observed by scanning electron microscope. The results show that the particles produced by electro-spraying chitosan solution encapsulates the surface of the wool fiber, and the anti-pilling result is increased by more than 1 level. After electro-spraying of hydrogen peroxide solution, a certain destructive effect was observed on the surface scales of the wool fiber, and the anti-pilling grade is increased by more than 0.5 level. Joint electro-spraying hydrogen peroxide and chitosan solution treatment to the wool fabrics for a long time (e.g. 240min) demonstrates the best anti-pilling effect.
