摘　　要：利用低温等离子体技术对PTT织物进行改性,在氧气存在下经等离子处理后接枝丙烯酸。通过对处理后试样进行染色性能测试,系统地研究了各处理方法所涉及的实验参数,如放电功率、放电时间、工作压强、接枝反应时间等对PTT织物染色效果的影响,通过Datacolor测色配色仪测定K/S值。研究结果表明:采用等离子体处理方法并进行接枝可以使试样表面引入极性基团,PTT织物的染色性明显改善,在放电功率70 W、丙烯酸浓度80%、工作压强30 Pa、处理时间7 min、反应时间6 h的条件下,染色性能较好。Low temperature plasma technology is used to modify PTT fabric. Grafting of PTT is done in the presence of oxygen. The effect of different grafting method and different parameters, such as discharge power, discharge duration, working pressure, grafting reaction duration on the fabric dyeing are discussed systematically by measuring the K/S value of dyed fabric after grafted by using Datacolor instrument. As shown from the experiments, polar groups can be introduced on the surface of ~ fabric because of the plasma grafting treatment, which promots the dyeability of FT fabric obviously. On the conditions of TOW discharge power, 80% acrylic acid concentration, 30Pa working pressure, 7minutes treating duration and 6hours reaction duration, the dyeability of PTT fabric shows much better.
