Uticaj obrade niskotemperaturnom plazmom na bojenje konoplje

Obrada niskotemperaturnom plazmom povećava brzinu iscrpljenja boje, završno iscrpljenje i intenzitet obojenja tkanine od konoplje. Poboljšanja posle obrade plazmom su izraženija kod bojenja bojom C.I. acid blue 113 nego kod C.I. direct red 81. Promena ponašanja prilikom bojenja je posledica nagrizanja i oksidacije površine vlakna konoplje plazmom. Low-temperature plasma treatment of hemp fabric causes an increase in dyeing rate, final dye exhaustion and dyeing strength of dyed samples. The positive effect of plasma treatment is more prominent in case of dyeing with C.I. acid blue 113 than with C.I. direct red 81. The observed changes in dyeing behavior could be explained by plasma etching and oxidation effect on the hemp fiber surface.
