New Trends in Textile Printing and Decolourization via Plasma (Paperback)

New manufactured plasma device has proved its efficiency in color removal and degradation of six different anionic dyes at lower discharge power and exposure time. Ozone concentration plays a great role on the (η) % of dyes removal for all the six dyes used in this work. The degradation of some dyes reached up to 95-99% at ozonation time 90 sec. Plasma technology assists printing of different fabrics (blend, nature and synthetic) with nature dyes. Cotton, polyester, wool and their blends with polyester could be successfully printed with pigment technique containing natural dyes then fixed with plasma. DBD plasma fixation enhanced the printability of all treated fabrics and increased their color strength nearly to the triple compared to the control ones. Fastness properties as rubbing, washing & light are all improved to excellent after DBD plasma fixation.
