摘　　要：涤纶织物采用常压空气等离子体表面改性后,放置在特定环境条件中,研究放置时间对涤纶纤维表面形貌、化学组分、润湿性以及直接喷墨印花性能的影响。试验结果证实,等离子体对织物表面的物理刻蚀作用不存在时效性,而纤维表面化学元素含量和润湿性能则随放置时间呈现出规律性变化,从而影响织物喷墨印花性能。涤纶织物经等离子体处理后,应尽可能在24 h内进行喷墨印花。The polyester fabrics were modified via atmospheric-pressure air plasma and stored at certain ambient condition. The effect of ageing process on surface morphology, chemical composition, wettability and inkjet printing performance of polyester fabrics was investigated. No evidence of morphological change was found during the storage time. The polar group had a loss which accelerated the ageing of the wettability of treated polyester fabric. It was found that the polyester fabric should be car- ried out ink-jet printing as early as possible （within 24h） after plasma treatment in order to keep the best effect of modification.
