摘要：

利用静电纺丝法制备聚乳酸（PLA）包覆相变材料的纳米纤维膜，为了改善其与普通织物间的复合牢度，首先对其进行等离子体处理，再同粘胶、羊毛织物进行复合，探讨了等离子体处理复合织物前后及各材料之间在保温、透气透湿、拉伸强力和剥离强力方面的差异。结果表明：等离子体处理前后粘胶/PLA/羊毛复合织物的透气性低于羊毛织物，处理前后的透湿量较羊毛/ 粘胶复合织物分别降低76.5%和62.5%；拉伸强力高于PLA/相变材料纳米纤维膜；粘胶/PLA/羊毛复合织物经等离子体处理前后的克罗值比粘胶/羊毛复合织物分别提升了18.07%和17.78%；等离子体处理后的粘胶/PLA/羊毛复合织物在剥离强力性能上较处理前提升了34.4%.

Abstract:

The PLA/phase change material nanofibers membrane was prepared by electrospinning method. In order to impeove the adhesion between nanofibers membrane and fabric, the nanofibers meinbrant was fitrsitly treated by plasma technology, and then combined with viscose fabric and wool fabric. The differences of the insulation, air permeability, moisture permeability, tensile strength and peel strength among materials after plasma treatment were discussed. The results showed that the air permeability of plasma untreated adn treated viscose viscose fiber/PLA/wool composite fabric mainly depended on wool fabric and both of them were lower than wool fabric, and the water vapor permeability were decreased 76.5% and 62.5%, respectively. The PLA nanofibers membrane played a more important role in tensile strength of plasma untreated and treated viscose fiber/PLA/wool composite fabric, and the tensile strength of which were higher than PLA nanofibers membrane. Compared to the viscose/wool composite fabric, the crow value of plasma untreated and treated viscose fiber/PLA/wool composite fabric increased by 18.07% and 17.78%, respectively. The peel strength properties of viscose/PLA/wool composite fabric subjected to plasma treatment added up to 34.3% in comparison with untreated composites.
