Journal Title: Annals of the University of Oradea. Fascicle of Textiles, Leatherwork - Year 2016, Vol 0, Issue 2
Abstract
Nowadays natural dyes have been attracted by many researchers and firms due to demands on sustainable and nontoxic products. In this study the mature berries of bay laurel (Laurus nobilis L.) were collected from trees located Kuşadası Turkey. The berries dried at 25oC and % 20-25 relative humidity. Dried berries milled and extracted with ethanol. Extracted dye was used. Three mordanting procedure (pre, meta and post mordanting) and two concentrations were applied to wool yarns. Cupric sulfate, ferric sulfate, potassium dichromate and alum was used as mordant Color strength and colorimetric values were measured by Konica-Minolta 3600D spectrophotometer. Fastness to washing, perspiration and light were applied according to ISO 105C06 (A1S), ISO 105E04 and ISO 105B02 (method 2) respectively. The highest color strength (K/S) value was 16.6405 and was obtained in the case of premordanting with cupric sulfate at 2 gr/L concentration. If the a* and b* values were examined, the conditions at highest color strength, the yarns had yellow color with a reddish hue. Generally, the fastness properties were moderate and good results were obtained in the case of premordanting procedure. The results show us ethanol extract of bay laurel berries can be used for dyeing of woolen products.
