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...

In this investigation dyeing of alginate fiber was carried out after cationic treatment of 11 EPTAC (2, 3-Epoxypropyl Trimethyl Ammonium Chloride). Optimum dyeing process and 12 parameter show good dyeing performance when alginate fiber dyed with rhubarb dye. In addition 13 to cationic treatment is taken into account for alginate fiber to improve fastness, color strength, 14 breaking strength. ...

Increasing environmental awareness has led to a growing interest in natural dyes the textile dyeing industry as consumers become more aware of toxicity synthetic that are harmful environment and health. Although environmentally friendly compared dyes, general their performance is less than dyes. Typically, metallic mordants used enhance affinity materials, perhaps this process breaks journey gr...

Penggunaan pewarna alami dalam industri tekstil khususnya pewarnaan kain tenun Timor semakin diminati, namun warna yang dihasilkan cenderung tidak tahan luntur terhadap pencucian sehingga dibutuhkan mordan sebagai pengikat dan serat kain. Pewarna berasal dari bahan alami, selain berfungsi pemberi penguat warna, juga memiliki aktivitas fungsional seperti antibakteri antioksidan. Penelitian ini d...

In this study, all conditions of the natural dyeing process cotton fabric with antibacterial efficiency, extracted from leaves nettle were optimized using a central composite design. The are: concentration 16.943 g, temperature 50 °C, time 40 min, and color strength obtained at optimum condition was 1.53. Nettle dye is applied to fabrics by Pad-Dry-Cure method for imparting properties textile p...

FT-IR spectroscopy is a nondestructive technique that can be utilized for the qualitative characterization of natural dyes and dyed substrates through structure elucidation. This work aimed at dye extract from Beta vulgaris peels pomaces surface analysis optimally dyed-mordanted cotton (cellulosic) fabric using Fourier Transform Infrared (FT-IR) spectroscopy, as well colour fastness tests (ligh...
