低温等离子体处理木棉纤维的染色性能

为提高活性染料对木棉纤维的染色性能，引入低温等离子体技术对木棉纤维进行前处理，采用SEM和FT-IR对其形态和结构进行表征，着重考察了强碱处理、半碱处理、等离子体处理及等离子体结合半碱处理四种不同前处理工艺对木棉纤维强力及其染色性能的影响。结果表明：采用四种前处理工艺均能迅速提高纤维的吸水能力和染色性能，等离子体处理仅仅在纤维的表面，采用等离子体结合半碱处理工艺，可以有效地减少强碱处理对木棉纤维机械性能的损伤，并可以有效地改善活性染料的染色性能。以活性橙X-EN染色为例，经过等离子体结合半碱处理，上染率和固色率分别达到86.63 %和70.32 %。

Dyeing properties of kapok fiber treatedby low temperature plasma

Low temperature plasma as a pretreatment technology was adopted to improve the kapok fiber dyeing behavior. The micromorphology and structure were investigated by SEM and FT-IR. Effect of status on mechanical properties and dyeing properties of kapok fiber was investigated emphatically with four different processes including strong alkaline treatment, semi alkaline treatment, low temperature plasma treatment and semi alkaline treatment combined with low temperature plasma treatment. The research result shows that the four pretreatment processes can rapidly improve the water absorbing capacity and dyeing performance. Low temperature plasma treatment processes on the surface of fiber. Semi alkaline treatment combined with low temperature plasma treatment can effectively reduce the mechanical damage caused by alkaline treatment and improve the dyeing ability of the reactive dyestuff. Taking Reactive Orange X-EN as an example, its rate of dye-uptake and fixation could reach 86.63 % and 70.32 %, respectively, after the treatment of semi alkalinetreatment combined with low temperature plasma.
