低温空气等离子体改善聚丙烯纤维的吸湿性

Moisture absorption property of polypropylene fiber modified by air low-temperature plasma

研究低温空气等离子体对聚丙烯纤维吸湿性的影响。实验结果表明,经空气等离子体处理后,聚丙烯纤维的微观表面出现了明显的凹坑和裂纹,吸湿性能得到了提高。

The method of improving the moisture absorption of polypropylene fibers was studied.Especially,the surface modification technique of air low-temperature plasma on polypropylene fibers was discussed.The results show the micro-surface of polypropylene fiber appears as obvious concave and crackle,and the moisture absorption is increased after plasma treatment.
