【摘要】 应用外部电容耦合式低温等离子体处理装置．在不同处理条件下，对PET工业长丝进行表面改性。并通过失重、回潮率和染色实验等方法，研究了处理前后样品的吸湿性、染色性等的变化。结果表明，处理后样品的吸湿性有较大提高，可达到未处理样品的2倍；经处理后的涤纶纤维对分散性染料的染色有一定的改善作用；处理后样品的失重随处理时间的延长而增加，而其强度几乎无变化。更多还原

【Abstract】 Surface modification of PET industrial fibre is investigated by using low temperature plasma with different treatment time, power and atmosphere. With appropriate treatment conditions, the dye uptake and the water absorbability of the fibre are increased by 85% and 11o% respectively, and a little part of the weight of the fibre loses, but the strength of the fibre is almost maintained.更多还原
