低温等离子体是改变纺织材料物理和化学性能的有用技术。在本实验中，研究了低温等离子体放电处理（氦气）在不同持续时间和磁场变化下对聚丙烯纤维和织物的物理、机械和化学性能的影响。等离子处理主要通过在纤维表面产生微裂纹和增加表面摩擦力来引起物理变化。通过这样的处理，提高了纤维的润湿性和染色性。随着可染性的提高，光反射减少，纤维在处理后变得更加暗淡。结果表明，较长时间的处理不仅增加了表面摩擦力，而且增加了耐磨性，而对纤维强度没有太大损害。这可能是一种生产消光和半消光聚丙烯纤维的方法。
Low temperature plasma is a useful technique to change the physical and chemical properties of textile materials. In this experiment, the effect of low temperature plasma discharge treatment (helium) on physical, mechanical and chemical properties of polypropylene fibers and fabrics has been investigated for the different duration with variation of magnetic field. Plasma treatment causes mainly physical changes by creating microcrack on fiber surface and increasing surface friction. The wettability and dyeability of fiber are increased by the treatment in such a way. As to increase in the dyeability, light reflection decreases and the fibers get duller with the treatment. The results show that in longer time treatments not only increase the surface friction but also increase the abrasion resistance, without much damage to the fiber strength. This may be a method for production of dull and semi dull polypropylene fibers.
