Abstract
Ozone plasma treatment is accessible to be applied on shading adjustment and colour fading because of the capacity of ozone production. It is a green process that treats dyed cotton fabric under dry condition so as to avoid chemical pollutants. This study means to explore colour reflectance of decolourized sulfur dyed cotton texture using ozone plasma treatment. Sulfur dyed cotton textures with various colour depths (0.5%, 1.5%, 2.5%) were set up to be treated different plasma parameters, including ozone air concentrations (10%, 30%, 50%, 70%), water contents in terms of weight percentage (35%, 45%) of fabric and ozone air plasma treatment periods (10 mins, 20 mins, 30 mins). The colour fading result is assessed by the colour reflectance in percentage (R%) utilizing spectrophotometer under CIE standard illuminant D65. The valid colour fading based on high percentage of reflectance was demonstrated from plasma treatment under higher ozone air concentration (50% and 70% ozone in air) and longer time length of plasma treatment (20 mins and 30 mins). The level of water content contained in the cotton fabrics is appeared to have noteworthy relationship with the degree of decolourization.

Ozone plasma treatment has been a compelling strategy for surface modification of textile fabrics by a dry etching process [3] [4]
Summary
Notwithstanding, some conventional colour fading technologies such as acid washing and bleaching which contaminate enormous amount of water with chemical concoctions utilized in process [1]. Low temperature plasma treatment with air contains clear yield during process and with eco-accommodating setting with no toxic pollutant discharge and reduction of handling time has been presented. According to the eco-friendly nature of plasma, a specific benefit of ozone plasma treatment over other traditional textile finishing strategies is the likelihood to control the process parameters including ozone concentration in air, water content and time length for plasma treatment. Just as altering the morphology and surface chemical structure of the fiber [5], the impact of plasma treatment on the colour fading level of 100% sulfur dyed cotton knitted fabrics were examined in this study. The colour shading properties of plasma-treated cotton fabrics were evaluated from the measurement of colour reflectance data (R %) in visible range
