An Approach to the Influence of Particle Size Distribution of Leuco Vat Dye Converted by a Reducing Agent
Fibers and Polymers 2006, Vol.7, No.2, 164-168 An Approach to the Influence of Particle Size Distribution of Leuco Vat Dye Converted by a Reducing Agent Woo Sub Shim*, Jung Jin Lee1, and Renzo Shamey Fiber and Polymer Science Program, North Carolina State University, Raleigh, NC 27695-8301, USA 1Department of Textile Engineering, Dankook University, Seoul 140-714, Korea (Received January 25, 2006; Revised March 23, 2006; Accepted April 2, 2006) Abstract: Three vat dyes have been applied to regular viscose rayon and their dyeing and wash fastness properties were eval- uated. Particle size determination was undertaken to obtain information about the size of dye particles converted by a reduc- ing agent, to see if dye particle size has an affect on dyeing properties of regular viscose rayon. It is observed that viscose rayon exhibits more dyeability with reducing agent concentrations between 5-7.5 g/l. Also, we found that the vat dyeing sys- tem is greatly affected by the particle size of the vat dye converted to leuco form by a reducing agent. Keywords: Particle size, Particle size distribution, Reducing agent, Viscose rayon, Vat dye, Dyeing properties, Wash fastness Introduction (Na2S2O4). The name “hydro” is commonly used for sodium hydrosulfite in the dyehouse. Reduction is done in the presence Vat dyes are used to dye cellulosic fibers in relatively dull of sodium hydroxide (NaOH) which is usually called caustic. shades requiring good fastness. They are insoluble in water The quantities of caustic and hydro required depend on how and cannot be used directly for dyeing cellulosic fibers. -

All rights reserved. http://tarek.kakhia.org - Introduction : Natural dyes are dyes or colorants derived from plants, invertebrates, or minerals. The majority of natural dyes are vegetable dyes from plant sources – roots, berries, bark, leaves, and wood — and other organic sources such as fungi and lichens. Archaeologists have found evidence of textile dyeing dating back to the Neolithic period. In China, dyeing with plants, barks and insects has been traced back more than 5,000 years. The essential process of dyeing changed little over time. Typically, the dye material is put in a pot of water and then the textiles to be dyed are added to the pot, which is heated and stirred until the color is transferred. Textile fiber may be dyed before spinning (dyed in the wool), but most textiles are yarn- dyed or piece-dyed after weaving. -

Removal of Azo and Anthraquinone Dye by Plant Biomass As Adsorbent – a Review

However, the supply of clean water had led to a decrease as pollutants such as dyes had caused a major negative impact on pure and clean main water bodies. In recent years, textile industries have developed and contributed to more than 50% of dye wastewaters in the world. The improper method of discharging dye effluent to the aquatic environment caused the destruction of habitat and degradation of water quality. Advanced treatments such as photocatalysis, electrooxidation, the Fenton process, and biological treatment via bacterium are often used for dye wastewaters. However, these treatment processes are often expensive in operation and maintenance. In conjunction, adsorption is one of the efficient, cost-effective, and environmentally friendly treatment methods. The adsorbent most widely used is the activated carbon adsorbent. Activated carbon comes in two forms, granular activated carbon (GAC) and powdered activated carbon (PAC). There are two methods to activation of carbon that are physical activation and chemical activation.
