Abstract

Non-functionalized and functionalized Tagetes minuta (TaMi) dye obtained using methanol and water showed varied fastness onto cotton fabric. Furthermore, HPLC profile of the methanol dye showed more peaks and hence was expected to be richer in secondary metabolites that impacted on the quality of the dye. This was confirmed from the IR spectrum which showed more functional groups from this dye as compared to the water dye. The functionalized methanol dye exhibited good fastness onto cotton textile and minimal bleaching effects, as compared to non-functionalized H 2 O and MeOH dye. Furthermore, the process involved the use of low quantities of the dye material/solution as compared to non-functionalized dye, hence resulting to less impact on environmental degradation. The colors of the textiles produced from the methanol functionalized dye were highly resistant to fading or running. The cotton fabric articles that were tri-mordanted at 80-90 °C and dyed using the functionalized dye exhibited uniform absorption of color of the dye and good fastness. Functionalization of the methanol TaMi dye was obtained by the reaction of the TaMi dye with 1,4-butanediol diglycidyl ether (BDDE). The alum tri-mordanted textile materials produced brighter colors of brown as compared to the singly alum mordanted fabrics. This is due to the tannin factor in tri-mordants that led to the brightening effect. Furthermore, longer duration of time for tri-mordanting might have had a greater impact to the brightness effect. Additionally, characterization of the dye obtained using the two solvents was done using HPLC and IR. The formed functionalized dye has many applications as colorants in textiles, paints, inks, plastics, cosmetic articles and electronic materials.

Highlights

1.1 TaMi dyes TaMi dye is a natural dye from a plant known as Tagetes minuta, which is known as Inabutsaka in Luhya[1]
3.1 The TaMi dyestuff and dye solutions/baths A dark brown dye stuff was obtained after grinding the inflorescences parts of Tagetes minuta plant, resulting to dark brown dye solutions from the three solvents used: MeOH, H2O and functionalized MeOH
3.2 The dyeing process After the dyeing process on to cotton fabric, there were no substantial differences in terms of the colours of the cotton fabric as all the three dye solution resulted to dark brown fabrics with minimal differences in their shades

Summary

Introduction

1.1 TaMi dyes TaMi dye is a natural dye from a plant known as Tagetes minuta, which is known as Inabutsaka in Luhya[1]. In 2009, Mibey et al from Moi University discovered the use of this plant, which is a stubborn weed, as a natural dye applied mainly onto cotton fabric which is currently being used in Rivatex textile industry, Kenya[2]. The use of functionalized dye in textile coloration usually results to good fastness onto fabric that leads to reduction in environmental pollution as compared to the traditional dyeing methods.
