Title

Green Dyeing of Woolen Yarns with weld and Madder natural Dyes in the Presences of Biomordant

Pages

  34-45

Abstract

 Nowadays, using sustainable dyeing process has become a necessity, but does not meet performance requirements. Application of biomordants was recommended to enhance the quality of dyeing. In order to design a green dyeing process, oak extract as bio-mordants and madder and weld luteola as natural dyes were used. The FTIR-ATR spectra of the washed wool yarn, mordanted wool yarn and mordanted dyed wool yarns confirmed bonding of wool yarns to the green mordant and dyes through a comparing chemical structure. The effective linkage between yarn, mordant and dye molecules removes the C-N peaks in FTIR-ATR spectra. After dyeing process, fastness and colorimetric attributes of dyed wool yarns were investigated. The K/S values of dyed wool yarns with extracted madder and weld luteola was quantified, properties including light, wash, and rubbing fastnesses were defined as per ISO standard methods.
