Before the First World War, almost all dyes were applied from solution in an aqueous dyebath to substrates such as cotton, wool, silk and other natural fibres. However, the introduction of a man-made fibre, cellulose acetate, with its inherent hydrophobic nature, created a situation where very few of the available dyes had affinity for the new fibre. Water-soluble anionic dyes had little substa...

In this work, raw fibers of a local species of stabraq (milkweed) were scoured, bleached and blended with cotton fibers with a ratio of 75/25 (cotton/stabraq). The improved stabraq fibers, scoured and bleached cotton and the blended fibers were spun into fine yarns and then they were subjected to dyeing with two types of reactive dyes namely, cold brand and high exhaustion brand reactive dye at...

To increase the color range of textile. Dyeing is to be done with more than one color-shedding substances, However before the conduction of Dyeing with the form of combining color-substances, the capability and probability of the combination, that is to be tested with the scale of degree in compatibility, has to be considered. Bearing in mind the necessity of producing a high range of color in...

The main objective of this work was to increase the retarding effect of the acid dye Telon(®) Blue RR (C.I. Acid Blue 62; DyStar, Frankfurt, Germany) release on polyamide fibres dyeing by encapsulation of the dye in liposomes as an alternative to synthetic auxiliaries, in order to reduce effluent pollution. The retarding effect achieved with the use of mixed cationic liposomes of dioctadecyldim...

Hair dyes are more and more used and the role of the exposure to these products in the development of skin reactions in the exposed region is suspected. The aim of this study is to assess the effects of hair dyes on facial skin and scalp sensitivity by performing a Computer Assisted Web Interview on 1257 women older than 15 years old. Differences were observed in the scores evaluating facial sk...

Microbial iron reduction is an important biogeochemical process and involved in various engineered processes, including the traditional clay dyeing processes. Bioaugmentation with iron reducing bacteria (IRB) is generally considered as an effective method to enhance the activity of iron reduction. However, limited information is available about the role of IRB on bioaugmentation. To reveal the ...

A novel chitosan-based biopolymer dye possessing antibacterial properties was synthesized by reaction of O-carboxymethyl chitosan and Acid Red GR. The synthesized materials were characterized by Fourier transform infrared spectroscopy (FTIR), degree of substitution (DS), X-ray photoelectron spectroscopy (XPS), thermogravimetric analysis (TG), X-ray diffraction (XRD), water solubility test, anti...

Laccase efficiently catalyses polymerization of phenolic compounds. However, knowledge on applications of polymers synthesized in this manner remains scarce. Here, the potential of laccase-catalysed polymerization of natural phenols to form products useful in hair dyeing was investigated. All 15 tested phenols yielded coloured products after laccase treatment and colour diversity was attained b...

The visual appearance of seamless dyed edges of luxury leather goods represents a key issue in terms of quality grading since a high-quality leather has to be characterized by homogeneously coloured and shaped edges with uniform ink thickness. Despite a huge literature produced by scientific and technical community to automate many leather manufacturing processes, since leather patches are ofte...
