低温等离子体-壳聚糖在涤纶织物喷墨印花中的应用

Application of Low-temperature Plasma Chitosan in Inkjet Printing of Polyester Fabrics

采用低温等离子体/壳聚糖协同工艺对涤纶春亚纺织物进行表面改性处理,再采用HDL型高温分散直喷墨水对织物进行喷墨印花。试验结果表明,低温等离子能够使涤纶织物表面产生刻蚀,引入亲水性基团,以涤纶的失重率和吸湿性能为评价指标,等离子体改性涤纶春亚纺织物的最佳工艺为时间6min、压强40Pa、功率200W。经过低温等离子体/壳聚糖改性工艺处理后的涤纶织物吸湿性能、印花色深得到明显提高,印花后的织物具有较好的耐水洗、耐摩擦和耐升华色牢度。

The low-temperature plasma/chitosan synergistic process was adopted to modify the surface of polyester Chunya textiles,then HDL type high-temperature dispersed direct jet ink was used for inkjet printing of the textiles.The experimental results showed that low-temperature plasma could cause etching on the surface of polyester textiles and adding hydrophilic groups.Taking the weight loss rate and moisture absorption performance of polyester as the evaluation index,the optimal process for plasma modified polyester Chunya textiles was time 6 min,pressure 40 Pa and power 200 W.The moisture absorbing performance and printing color depth of polyester textiles were significantly improved after low-temperature plasma/chitosan modification processing,while the printed textiles had high color fastness to washing,friction and sublimation.
