Natural dyes play an important role in sustainable dyeing processes. However, natural yellow with good performance are rare. Traditional have issues, such as a narrow color range and poor light fastness. In this paper, new dye was extracted from low-cost herb Geranium caespitosum L. (G. caespitosum). addition, the composition analyzed using UV-visible spectroscopy. The process of G. on wool fab...

Abstract The study tested the use of Viscobleach as a multi-scouring agent for pretreating cellulosic fabrics (cotton, viscose, and linen) instead using traditional agents (caustic soda, soda ash, hydrogen peroxide). results showed an increase in whiteness absorbency viscose linen pretreated with Viscobleach. color strength (K/S) increased all shades cotton medium dark linen. also that dye pick...

This study evaluated the color fastness and crust quality of eco-printed leather using various types mordant in natural dye mangrove extract. used 20 sheepskin crusts bark experimental employed a Completely Randomized Design (CRD) with different as treatments. The were Aluminum Sulfate (Al2(SO4)3), Calcium Carbonate (CaCO3), Citric Acid (C6H8O7), Ferrous (FeSO4). results showed that use (FeSO4)...

Resonance Raman spectroscopy offers several advantages in the studies of ink jet prints stemming from its inherent selectivity and sensitivity. These include the possibility to obtain direct information on the chemical interactions between the paper and ink that play a major role in long-term print fastness. However, resonance Raman techniques can suffer from obtrusive fluorescence from coloran...

Today, natural colorants are emerging globally due to their safety and environmental friendly characteristics. Natural dyes have been employed in dyeing Persian carpet piles for many years. Food and fruit industry wastes are one of the main sources of colorants which can be employed for textile coloration. Eggplant (Solanum melongena), a member of the family Solanaceae, is used in food recipes....

The recent pandemic scenario has caused demand for green products that have medicinal aspects, as well greener approaches global health. Natural dye from plants, particularly harmal seeds, is an excellent alternative to carcinogenic yellow synthetic dyes. current study been conducted isolate natural colorants seeds in methanolic medium through Gamma-Assisted Extraction (GAE). dyeing variables a...

Acid dyes are often used to improve the decorative properties of bamboo products. However, the use of these dyes is problematic because they run easily. This study examined the use of chitosan as a fixing agent to address this issue. The study also investigated the interaction between dyed bamboo powder and dyed veneers pre-treated with chitosan. Powder was dyed at various pH values with acid s...
