Abstract

Humans have been using plant-based dyestuff for centuries as the main provider of dyes for industrial products such as textiles, food, leather, etc. Specifically in Turkey, such plants have been used for the dyeing of the fibre and yarn of cotton, wool and silk used in handicraft products, such as carpets, rugs, fabrics, etc. With the discovery of synthetic dyestuffs in the mid-19 th century, natural dyes, and thus, natural dyeing, gradually lost importance, although today, plant-based dyestuffs are again gaining popularity as a result of the rising popularity of the natural and the sustainable concept. The purpose of the present study is to investigate the dyeing effect of solutions obtained from gallnut dyestuffs and mordants from whey, yeast, lye and mushroom extract, with the intention being to identify light, crock and wash fastness levels and examine their usability in today’s textile sector. Dyeing cotton fabric samples with gallnut dyestuffs and natural mordants has allowed some important conclusions to be drawn with respect to human and environmental health. Keywords: Gallnut dyestuff, Light Fastness, Crock Fastness, Wash Fastness, Natural mordants

Highlights

Natural dyestuff and natural dyeing is as least as old as the history of textiles; and it is known that the natural dyeing of textile fibres started in India and Mesopotamia in the 2000s B.C. (1)
This study is the first step in the use of gallnut, the dyeing characteristics of which have been well documented in literature, as a dyestuff in the textile sector, in the investigation of the dyeing effects and fastness on different fabrics under industrial conditions and in the transfer of natural dyeing processes to the commercial sector
Within the scope of the study, it was concluded that the light fastness obtained when dyeing cotton fabric specimens with pre-mordanting using lye, yeast, whey and mushroom extract is at a medium level, except for whey

Natural dyestuff and natural dyeing is as least as old as the history of textiles; and it is known that the natural dyeing of textile fibres started in India and Mesopotamia in the 2000s B.C. (3) At these times and in the periods that followed, tests were made in many regions of the world with different auxiliary substances to identify natural dye-bearing plants, and attempts were made to achieve various colour tones. Analysing the development of natural dyeing among the Turkish tribes, it is possible to say that dyestuff plants have existed and been cultivated in Central Asia and Anatolia throughout history.
