摘要
采用常压氩气介质阻挡放电(DBD)等离子体对聚乳酸(PLA)纺黏非织造材料进行表面改性处理,以提高材料的亲水和染色性能.考察了等离子体处理电压对PLA非织造材料的表面形貌、接触角、芯吸高度、表面化学成分、染色性能以及拉伸断裂强力的影响规律.研究结果表明:经氩气DBD等离子体处理后,PLA非织造材料的表面粗糙度明显增加;随着等离子体处理电压的增加,PLA非织造材料的接触角先减小后增加,当处理电压为200 V时,接触角达到最小值,此时材料的芯吸和染色性能的提高最显著.
In this paper, PLA spunbond nonwovens materials were treated by the atmospheric pressure dielectric barri- er discharge （DBD） to improve hydrophilic property and dyeability of the material. The effect of treatment voltage on the surface morphology, contact angle, wicking, surface chemical component, and dyeability of the PLA materials were discussed. SEM images showed that the surface roughness of PLA nonwoven materials increases significantly after the treatment. The results also showed that with the increase of the treatment voltage, the surface contact angles first decreased and then tended to increase with the further increase of treatment voltage. When the treatment voltage was 200 V, the contact angle got to the minimum value, and at this time, the increase of the wicking and dyeing performance of the material was the most significant.
