Investigations of dye adsorpThe effects of tannic acid and Rhodamine B on the zeta potention on the materials and the electrical and thermodynamic tials and surface free energy components of polyester fabric (Daproperties of the fiber/solution interface are fundamental for cron 54, Style 777) were studied. Knowledge of these parameters understanding the dyeing mec...

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 ...

Comet assays were carried out to evaluate DNA damage in human lymphocytes from 20 volunteers before and after hair dyeing. DNA damage in lymphocytes was found to be slightly higher in volunteers after hair dyeing. Tail moments before and after hair dyeing were 1.47 +/- 0.41 and 1.75 +/- 0.29 respectively (p<0.0008). DNA damage in lymphocytes showed significant difference with treatment and heat...

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...

The present work deals with the ways of testing the compatibility of reactive dyes with cotton in different textile industries in Bangladesh. This report includes three laboratory trials that were carried out for three different reactive dyes to check the compatibility for use in a dye recipe on cotton knitted goods. In this study, Spectrophotometric analysis was conducted and the fixation of e...

As people in the 21st century become increasingly environmentally aware, environmentally friendly products have come into focus. As such, environmentally friendly textiles and eco-textiles have become an international trend in research and development. Poly(lactic acid) fiber, which is biodegradable, holds much promise, but it is difficult to deep dye. This study used chitosan, succine anhydrid...

In the study of color matching in textile dyeing, regression algorithm is used to analyze the nonlinear relationship between the dye concentration and the color data in CIE-La*b* color space of dyeing sample, thereby providing theory basis for establishing mathematical model for textile dyeing. Statistical analysis is conducted on a number of experimental data and the model is tested by actual ...
