Examination of Dyeing Properties of the Dyed Organic Cotton Knitting Fabrics Using Yarrow (Achillea Biebersteinii AFAN and Achillea Millefolium L.)

In this study, organic cotton knitting fabrics were dyed with yarrows (Achillea biebersteinii and Achillea millefolium L.). The fabric samples were separately dyed with flowers and leave-stems of yarrows - alum and yarrow - alum - gall oak. A reverse-phase high-performance liquid chromatography with diode-array detection method was utilized for the identification of the coloring compounds of dyes in the dyed fabrics and the plant extracts. The extraction of dyes was carried out with a hydrogen chloride forward slash methanol forward slash water (2:1:1; v forward slash v forward slash v) mixture. Keampferol-O-glucoside, axillarin, luteolin-7- glucoside and patulitrin were determined in the dyed fabrics and extracts. The color coordinates and fastness values (washing, perspiration and rubbing) were investigated. Rubbing dry and wet fastnesses are excellent. Dyed organic knitting fabrics were studied calorimetrically and their color coordinates L*, a*, b*, C*, h, K/S, and increment E* values were given. Yarrow can be used in textile dyeing for yellow dyeing.

Automated summary

Organic cotton knitting fabrics were dyed with yarrows, and the coloring compounds of dyes were identified using a high-performance liquid chromatography method. Results showed that yarrow can be used for textile dyeing to achieve yellow coloring, with excellent color coordinates and fastness values in the dyed fabrics.
