摘　　要：采用高碘酸钠氧化嫁接乙二胺、聚乙二醇二缩水甘油醚(PEGDE)交联嫁接乙二胺和氨气低温等离子体处理3种改性工艺对亚麻织物进行表面改性,选用两种活性染料(活性艳红X-3B,活性艳蓝X-BR)对改性前后亚麻织物进行染色,结合上染率、嫁接率的变化,研究了工艺条件对染色性能的影响,确定最优改性工艺。结果表明,在这3种改性工艺中,PEGDE交联嫁接乙二胺改性后的亚麻织物染色效果最优。8%PEGDE、0.5 mol/L乙二胺在60℃、pH值=6的条件下反应10 h后的亚麻织物嫁接率达到11.2%,上染率达到89.39%。改性后亚麻织物的固色率、耐摩擦色牢度、耐皂洗色牢度和抑菌性能均得到一定程度的提升,染色性能更好。The surface of linen fabric is modified by three modification processes with sodium periodate oxidation grafting ethylenediamine,polyethylene glycol diglycidyl ether(PEGDE)crosslinking grafting ethylenediamine and ammonia low temperature plasma treatment.Two kinds of reactive dyes(reactive brilliant red X-3B and reactive brilliant blue X-BR)are used to dye the modified linen fabric.Combined with the change of dyeing rate and grafting rate,the influence of process conditions on dyeing performance is studied,and the optimum modification process is determined.The results show that among the three modification processes,the linen fabric modified with PEGDE crosslinking grafting ethylenediamine has the best effect.Under the conditions of modification at 60℃for 10 h with PEGDE 8%,ethylenediamine 0.5 mol/L and pH=6,the grafting rate of linen fabric can reach 11.2%and the dyeing rate can reach 89.39%.The fixation rate,rubbing fastness,soaping fastness and antibacterial properties of the modified linen fabric have been improved to a certain extent,and the dyeing performance is better.
