A method for the application of carbenes as reactive intermediates for surface modification of polymeric substrates has been developed; the efficacy of the process has been demonstrated by irreversible dyeing of polystyrene, polythene, nylon, silica, and controlled pore glass, and to a limited extent, polytetrafluoroethylene.

Traditional dyeing usually consumes a significant amount of water and salts, thus causing environmental pollution. Salt-free low-water has become an important research direction in the cotton fabric industry. The non-aqueous media technology, using decamethylcyclopentasiloxane (D5) as medium, achieved energy saving emission reduction this To investigate influence inorganic salts on properties r...

Water-soluble polymers have versatile applications but they are hardly used in wet processing of cellulosic substrates (cotton, viscose, jute, etc.), particularly in dyeing. In this paper, one such water-soluble polymer, polyacrylic acid has been synthesized, characterized and applied to viscose fabric in conjunction with various types of reactive dyes, namely triazinyl, vinyl sulphone, high ex...

Hand dyeing generates artistic representations with unique and complex patterns. The aesthetics of dyed patterns on a cloth originate from the physical properties of dyeing in the cloth and the geometric operations of the cloth. Although many artistic representations have been studied in the field of nonphotorealistic rendering, dyeing remains a challenging and attractive topic. In this paper, ...

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 study, 1...

The high production yields of pigments by Talaromyces spp. and their high thermal stability have implied that industrial application interests may emerge in the food and textile industries, as they both involve subjecting the colourants to high temperatures. The present study aimed to assess the potential application of the pigments produced by Talaromyces spp. in the textile area by studying t...

Rapid industrialization and urbanization results in the discharge of large amounts of waste to the environment, which in turn creates more pollution (Senan and Abraham, 2004). Synthetic dyes are extensively used in textile dyeing, paper printing, color photography, pharmaceutical, food, cosmetics and other industries. During textile dyeing, the amount of dye lost in effluent is dependent upon t...
