Global warming has become one of the most important factors threatening the world.The first place among the causes of global warming is taken by fossil fuels, which are mainly used for energy needs.The intensive consumption of fossil fuels causes the decrease of the world's fossil fuel reserves, environmental pollutio…

This study presents a comparative evaluation of chitosans derived from fungi ( Agaricus bisporus ) and mealworms ( Tenebrio molitor ) as sustainable antibacterial finishing agents for textile applications. The structural properties of fungal and insect chitosans were determined using Fourier transform infrared (FTIR)…

This study aims to comprehensively investigate the usability of white mulberry (Morus alba L.) leaf extract as a natural dye, including its fastness properties, antibacterial activity, and antioxidant activity. In the study, dyeing processes were carried out on cotton fabric, wool fabric, wool yarn, polyester, leather…

Some vegetable dyestuffs exhibit low affinity for natural fibers such as wool, cotton, and leather, which reduces their coloring efficiency. To enhance color uptake, transition metal salts such as copper sulfate (CuSO₄·5H₂O), iron sulfate (FeSO₄·7H₂O), alum (AlK(SO₄)₂·12H₂O), and tin chloride (SnCl₂) are commonly used…

The madder plant (Rubia tinctorum L.) is a valuable member of the large Rubiaceae family. Its roots and rhizomes contain anthraquinones, such as alizarin and purpurin, alongside their glycosides, which offer natural coloring for the textile, cosmetic, food, and pharmaceutical industries, while also demonstrating a ran…

Although one-bath dyeing of acrylic/cotton blend fabrics has been investigated at laboratory scale, its industrial application remains poorly understood. This study provides mechanistic insights into dye-fibre interactions, pH and ionic effects, and efficiency limitations, defining the operational boundaries for indus…

The resistance of colour to repeated domestic washing is a critical performance requirement for cotton fabrics dyed with reactive dyes, particularly in terms of maintaining acceptable wet fastness and colour stability. Although the washing fastness of reactive dyed products is generally good, colour change remains an…

Geleneksel boyama yöntemlerinde siyah renk; genellikle meşe palamudu, mazı meşesi veya nar kabuğu gibi tanen (tannic acid) oranı yüksek bitkisel kaynaklarla boyanıp demir sülfat (FeSO_4) ile mordanlanması sonucu elde edilmektedir. Ancak demir mordanın asidik yapısı ve oksidasyon etkisi nedeniyle özellikle protein esas…

Hastane kaynaklı enfeksiyonlar, hastanede kalış sürelerini artırmakta ve ulusal ekonomiler üzerinde baskı oluşturmaktadır. Antimikrobiyal direncin artması, yeni antimikrobiyal ajanların geliştirilmesini ve enfeksiyonların önlenmesine yönelik daha etkili yöntemlerin uygulanmasını gerektirmektedir. Antimikrobiyal teksti…
