Printing with Natural Dye Extracted from Impatiens glandulifera Royle

Invasive alien plants that damagingly overgrow native ecosystems can be beneficially used to produce natural dyes. Natural dyes are healthier and more environmentally friendly than synthetic dyes, so their use on textiles other products come into contact with humans is desirable. In this study, the possibility of using a dye extracted from purple petals invasive plant Impatiens glandulifera Royle (Himalayan balsam) for screen printing various substrates; woven fabrics different papers made virgin fibers, recycled fibers Japanese knotweed, was investigated. The prints were evaluated by color measurements fastness properties. With violet extract, purple-brown obtained brown substrates. They had excellent rub but faded significantly when exposed light. wash cotton moderate poor polyester fabrics, good resistance wet ironing. addition acid paste resulted in lighter color, alkali caused drastic change green, both additives increased light reduced treatments.
