等离子体表面改性对相变纳米纤维复合织物性能的影响

Effects of plasma treatment on the phase change nanofiber composite fabric

为改善相变纳米纤维复合织物的保温及服用性能,使用静电纺丝法制备了相变醋酸纳米纤维膜,并与羊毛和粘胶两种传统织物复合,制成相变调温三明治结构复合纺织品。在该复合织物的制备过程中,利用常压等离子体技术分别对复合织物各层材料进行了表面改性处理以提高其服用性能。通过测试各材料经等离子体处理前后的静态接触角及形貌,获得了最佳等离子体处理参数;比较了等离子体处理前后复合织物在保温性、透气和透湿性能上的差异。实验结果表明:等离子体的物理撞击作用能够提高复合织物的保温性能,并且增强了透气、透湿性能。说明了此种方法的必要性及其可行性。

In order to improve the heat preservation and wearability of phase change nanofiber composite fabric, a novel phase changenanofiber composite fabric with sandwich structure is made by firstly preparation of a phase change material/ cellulose acetate nanofiber filmwith electrospinning followed by compounding with wool and viscose fabric. During the preparation process, atmospheric pressure plasmatreatment is used onto each layer of composites to improve its wearability. The static contact angle and morphological observation of samplesare measured to obtain the optimum parameters of plasma treatment, as well as the air permeability and water vapor permeability. The resultsshow that the physical impact effect of plasma can improve the heat preservation and wearability of the composites with heat preservation, airpermeability and water vapor permeability increased by 19.4%, 84.6% and 65.7% respectively compared with the untreated one. It is provedthis project is necessary and effectively.
