An ecological approach has been obtained by using natural dyes and mordant for dyeing process. Silk fabrics dyed using natural mordants: powder of sour pomegranate and sweet pomegranate and mixture them. A beautiful red color were obtained by using theses mordants. The color of dyed silk fabrics was investigated in CIE Lab L, a and b and K/S values. Finally, all dyed fabrics were tested for was...

This study aims to determine the % solid content determination of concentration dispersing agent / leveler. Therefore, in order correct concentration, varied, namely 43.930%, 21.975%, and 14.650%, with each dispersing/averaging 0 g/l, 0.5 0.75 g /l, 1.5 g/l. Furthermore, preliminary testing power was carried out before immersion application. The results most optimal test were obtained at a vari...

Application of natural dyes in textile coloring has been widely used because it is more environmentally friendly than synthetic and able to produce various colors from one dye. In this study, cotton fabric was treated with chitosan at different concentrations (0, 0.25%, 0.5%, 1%) determine its effect on the color fastness using mango leaves extract as dyes. Fastness ironing, washing sun drying ...

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...

A series of disperse dyes, 9,10-anthraquinone containing dithiocarbamate, thiourea and triazole fragments, were prepared via consecutive refunctionalization aminoanthraquinones in our previous studies their structures confirmed by the 1H-, 13C-NMR, IR spectra, LC-MS elemental analysis data. The obtained compounds applied on polyester fabrics exhaustion method at 130?C pH 4.0-5.0, dyeing propert...

Abstract Progressive environmental awareness and legislation regarding the pollutants discharged from textile coloration plants allocate natural colorants in forefront position for dyeing printing of many substrates. In this study, a genuine dye was synthesized by combining diazonium salt m -anisidine with crude extract peanut skin. The melting point (SD) as well its Fourier transform infrared ...

Indonesia is rich in flora diversity, very potential for the development of natural dyes. The advantage dyeing fabrics with dyes that they contain antioxidants and environmentally friendly. purpose this study was to optimize process on chitosan-modified variations temperature solution ratio. used were kesumba keling seeds (Bixa Orellana) sappan wood (Caesalpinia sappan). analysis carried out va...

The goal of this project is to assess the effect natural dye absorption from turmeric powder on cotton fabrics. At commencement, fabrics are mordanted with two different processes, one synthetic mordanting, and another bio mordanting. Both mordanting processes done at 100°C temperature for 60 minutes then dyed 80°C minutes. Application was made mordants. After completing dyeing process, color f...

The process of bleach washing on denim fabrics produces a paler or lighter shabby effect. effect is produced by using an oxidizing agent. application sodium hypochlorite can cause decrease in color aging and high tensile strength. pH condition also affects the occurrence oxycellulose damage which will affect final result. Inappropriate very oxidation produce less Therefore, concentration NaOCl ...
