Abstract:
Before a rising awareness of consumers and producers regarding the problems caused by the use of synthetic dyes, using natural dyes and mordants extracted from the agricultural industries’ residues, such as peel from jaboticaba (Plinia cauliflora), pomegranate (Punica granatum L.), grape (Vitis sp.) and banana (Musa spp.), subjects of the research, is a solution for a less enviromental and human health harming production. The peel collected were oven-dried at 45ºC for 24h and aqueous extractions were carried out at 1:10 ratio, at 100ºC for 1h on a heating plate. Different exhaust dyeing conditions were tested, varying the pH and the mordants. The dyed fabrics were evaluated in spectrophotometer through the CIE L*a*b system. The results of the color fastness to washing and to light tests of the samples indicated that all of the residues have the potential to be used as dyes and mordants for textile dyeing.
