PLASMA ENHANCED MODIFIED (LOW TEMPERATURE AND SHORTENED TIME) DISPERSE DYEINGS OF POLYETHYLENE TEREPHTHALATE FABRICS WITH IMPROVED FASTNESS PROPERTIES

摘要

Within the context of environmental impact, the scope of the current study is focused on researching effect of low temperature plasma treatment on dyeing of polyester fabrics. This is done in terms of low temperature, short time and improved fastness. Plain weave 100% polyester fabrics were subject to low frequency plasma treatment under a well selected power and duration using acrylic acid (AA) monomer. Plasma polymerization treatment was investigated by considering water absorption, ESCA and SEM analysis outputs, followed by dyeing and related color measurements. Consequently, results were compared with dyed untreated fabrics. Additionally, washing and rubbing fastness were also examined to exploit the effects of plasma on permanentness of short time (<30 minutes) and low temperature (<110oC) dyeing compared to coventional disperse dyeing. This work5s appearant result was the effectiveness of acrylic acid plasma polymerization technique on dye uptake of polyester fibers in disperse dyeing. However, high impact result of the work was short time (30min) disperse dyeing of polyester fabrics. We can conclude that the mentioned method can be an alternative to conventional long time dyeing (60min) with acrylic acid plasma polymerzation treatment, increasing dry rubbing fastness. This results are promising for an ecological and energy saving alternative to conventional disperse dyeing.
