Dyeing of wool and cotton fibres with fruit rind of Juglans regia as natural dyes, and standardization of ancient dyeing procedure

Abstract

Vegetable  dyes  and  their  uses  are  known  in  an cient  time  more  than  2000  years  ago.  It  was  found  that  the discovery  of synthetic  dyes  reduce  the  use  of  natural  dyes  and  consequently  the  export  of  same  was  affected in large  extent.  However  due  to  non  toxic  nature,  eco-friendly  behaviour  and  properties  to  impart  variety  of colours  once  again  natural  dyes  are  getting  more  attention  of  chemists  and  dyers.  The  present  paper  deals with  optimization   of  dyeing  and  mordanting  of wool  and cotton  samples  with  fruit  rind  of  Juglans  regia  and standardization   of ancient  dyeing  procedure  and  also  the  fastness  studies  of  dyed  samples  toward  light  and washing.
