The aim of this study was to investigate the decolorisation effect of atmospheric pressure plasma treatment on knitted fabrics dyed with reactive dyes under different processing parameters, ie, air concentration, treatment duration and water content. The fabrics were dyed with reactive dye of a blue colour, and the colour depths were 0.5%, 1.5% and 3.0% on weight of fabric. The colour properties of untreated and plasma‐treated fabric samples were evaluated by means of reflectance, K/S and relative unlevelness index. The colour properties were evaluated instrumentally and quantitatively in order to study the decolorisation effect induced by atmospheric pressure plasma treatment. Experimental results revealed that the desired decolorisation effect was heavily influenced by the atmospheric pressure plasma treatment processing parameters. Although the desired decolorisation effect could be obtained by controlling the processing parameters of the atmospheric pressure plasma treatment, the treatment did not provide any significant reduction in the bursting strength of the fabric.

常压等离子体诱导的活性染料染色棉针织物脱色

这项研究的目的是研究在不同的处理参数(例如空气浓度,处理时间和含水量)下,大气压等离子体处理对用活性染料染色的针织物的脱色效果。织物用蓝色的活性染料染色,且色深为织物重量的0.5%,1.5%和3.0%。通过反射率K / S评估未经处理和经等离子体处理的织物样品的颜色特性和相对失平指数。为了研究由大气压等离子体处理引起的脱色效果,通过仪器和定量方法评估了颜色性能。实验结果表明,所需的脱色效果在很大程度上受大气压等离子体处理工艺参数的影响。尽管可以通过控制大气压等离子体处理的工艺参数来获得所需的脱色效果,但是该处理并没有显着降低织物的破裂强度。
