In this research, we investigated the dyestuff properties of dwarf elderberry (Sambucus ebulus), which has many pharmacological functions. Dyeing of cotton fabrics and wool yarns was carried out ...using Sambucus ebulus L. fruit extracts. Textile products were processed to pre–, meta–, and post– mordanting methods in the presence of iron sulfate (FeSO4), copper sulfate (CuSO4) and alum (AlK(SO4)2) mordants. Color analyses of dyed textile products were performed and, the results were examined in terms of washing, rubbing, and light fastness. According to the results, it was determined that wool yarns showed better dyeing potential than that of cotton fabrics in terms of washing fastness. While the highest K/S value was measured as 6.55 in cotton fabrics with the pre-mordanting method, the highest K/S value was measured as 14.90 in wool yarns. In addition, the highest color strength values were obtained in each three mordanting methods. While gray, beige, and cream color tones were obtained in dyeing cotton fabrics, beige, green, and gray color tones were obtained in dyeing wool yarns.
In the fight against the new type of coronavirus (SARS-CoV-2 causing Covid-19), which emerged in China in 2019 and caused the illness and death of many people all over the world, preventive measures ...come to the fore as vaccines have not yet been produced. These are physical distance, mask use, and hygiene. The use of masks has become mandatory all over the world and the production of alternative masks continues uninterruptedly. In this study, we aimed to produce an effective and breathing mask against the virus using antiviral and aromatic vegetable oils. As a result of the study, 100% cotton fabrics dyed with anti-microbial effective herbal dyes were treated with anti-viral, breathable vegetable oils, and new types of protective masks against coronavirus were produced, and odor emission times of the produced masks were determined.

with post–mordanting method for dyed cotton fabrics. While generally blue, burgundy, green and lilac color tones were obtained in cotton fabrics, burgundy, red brown and green color tones were obtained in wool yarns. As a result, it was determined that cotton fabrics exhibited better dyeing potential compared to wool yarns, and the highest color strength values were obtained using the post–mordanting method.

Morus nigra L. is a biologically important plant. In addition to the biological importance of the extracts obtained from its various parts, it is used as a material in various fields. In this work, ...dyeing properties of the cotton fabrics and the wool yarns with Morus nigra L. leaf extracts were investigated. In dyeing studies using Morus nigra L. leaf extracts, yellow tones were obtained in dyeing cotton fabrics, and green and yellow tones were obtained in dyeing wool yarns. Washing, rubbing and light fastness of dyed textile products were examined. According to the results, cotton fabrics showed better dyeing potential than wool yarns. As a result, Morus nigra L. leaf can be used as a natural dyeing agent in the dyeing of textile products.
