Colorful nanofibrous membranes have attracted much attention for their visual varieties and various functionalities. In this article, a colored solution electrospinning process was used to fabricate colorful hydrophobic poly(vinyl butyral) (PVB)/cationic dye nanofibrous membranes (NFMs) successfully. The color and morphology of these as-spun nanofibrous membranes have been analyzed by colorimet...

The purpose of a cross-sectional study was to investigate factors influencing the quality of life among Thai workers in textile dyeing factories. Samples included 205 Thai workers from five textile dyeing factories located in the suburban area of Bangkok in Thailand. Data were collected with a self-administered questionnaire. Scales of the questionnaire had reliability coefficients ranging from...

Many natural fibres, including wool, cashmere and silk, are protein-based materials; the dry weight of wool is almost entirely derived from proteins (Maclaren & Milligan 1981). As such, they possess an inherent structural and chemical heterogeneity not found in synthetic polymers. Although typically less heterogeneous than biological fibres, the rapidly emerging range of commercially available ...

Cotton hanks were dyed with three different sulphur dyes using non-sulphide reducing agents such as glucose, fructose, invert sugar and molasses. The alkalies employed for reduction were sodium carbonate and sodium hydroxide. Invert sugar as a reducing agent and sodium carbonate as alkali proved to be better as this combination gave results comparable to those obtained with the conventional sod...

An inclusive chemical definition of “reactive” dyeing textiles is introduced, encompassing the CI Azoic, Mordant, Reactive, Sulphur and Vat dye application classes. Such reactive increases fibre retention makes practically possible. The analogous dyes fluorescent probes as microscopic stains in biology medicine outlined, focussing on using with living cells. Parallels textile are noted, eg, enh...

This study presents a novel method for eco-friendly dyeing of cotton fabrics with direct dyes. Cotton fabric modified with chitosan-poly propylene imines dendrimer CS-PPI, and its dyeing and fastness properties were investigated using three direct dyes. The impacts of important factors, i.e., CS-PPI concentration, dye concentration, dyeing time, dyeing temperature, and salt concentration were i...

  Background :Despite the presence of many textile and dyeing plants in Iran, we couldn’t find similar studies in this country. Forthermore, considering progress in the dyeing process and engineering controls, assessment of respiratory system is important for these workers. The present study was performed to evaluate the respiratory system in dyeing workers.   Methods : In a cross-sectional stu...
