Reducing pollution in various industries such as textile is very important. In this paper, two parallel methods were used to reduce of the process and application dye. The first approach was selection plant-based dyes (Madder with botanical name Rubia tinctorum Reseda odorata) a tannin-based mordant (pomegranate peel Punica granatum). second extraction dyeing ultrasound media. efficiency madder...

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...

Nowadays, textile processing based on biotechnology has gained its importance in the view of stringent environmental and industrial safety conditions. The use of protease enzymes in protein fibers to improve some physical and mechanical properties is particularly interesting. In this research, wool yarns were first treated with different concentrations of protease enzymes in aqueous solution in...

Hand dyeing generates artistic representations with unique and complex patterns. The aesthetics of dyed patterns on a cloth originate from the physical properties of dyeing in the cloth and the geometric operations of the cloth. Although many artistic representations have been studied in the field of nonphotorealistic rendering, dyeing remains a challenging and attractive topic. In this paper, ...
