Destruction of Azo-Reactive Dyes by Ozonation and the Synergetic Effect of a Radio-Frequency Alternating Electric Field Inductance Device-Juniper Publishers


Discharge of textile wastewater into water-bodies causes serious environmental and health problems. Wastewater color remains due to the non-biodegradable nature of the dyes. However, treatment with ozone can lead to the destruction of the dye molecule, decolorizing thus the textile effluent. In this paper, treatment with ozone in a bubble column reactor resulted in rapid destruction of azo-reactive dyes, utilized primarily for dyeing cellulose fibers. Moreover, ozonation kinetics can be described as a mass-transfer-control process. Combining ozonation with a novel radio-frequency alternating electric field inductance device led to faster destruction of the azo-reactive dyes due to synergetic effects.

Reductive Discharge Ink-Jet Printing of Pre-Dyed Textile Fabrics

CURRENT TRENDS IN FASHION TECHNOLOGY & TEXTILE ENGINEERING - JUNIPER PUBLISHERS Authored by  David M Lewis Abstract Bleached cotton fabrics have been dyed with Remazol (sulphatoethylsulphone (Dystar)), Procion MX (dichloro-s-triazine (Dystar)) and Procion HE (bis-monochloro-s-triazine (Dystar)) reactive dyes to yield suitable coloured backgrounds for subsequent reductive discharge ink-jet printing. Silk fabric has also been dyed with an acid dye to provide an alternative substrate for subsequent discharge printing. Suitable white discharge inks have been formulated using either Decrolin (zinc sulphoxylate formaldehyde (BASF)) or Rongalit C (sodium sulphoxylate formaldehyde (BASF)), whilst coloured illuminating inks have been formulated using either vat or solubilised vat dyes. Inks containing both a discharging agent and an illuminating colour have also been developed. A process has been developed in which the free aromatic amine groups present in the discharged areas of white ...

  CURRENT TRENDS IN FASHION TECHNOLOGY & TEXTILE ENGINEERING - JUNIPER PUBLISHERS Abstract In the present investigation an attempt has been made to fabricate jute reinforced bagasse composites which was developed by layer by layer techniques of composite manufacturing methods. As it was known, previously ceramics and plastics materials have been more dominant in the world market. Due to the rapid growth of the applications of composite materials, they penetrate and conquer the new markets persistently. Nowadays, composites have become one of the most important engineering materials in various applications. This composite material has been made by using sugarcane bagasse as a filler, jute natural fiber as reinforcement material with PVA as matrix. The fabricated composite materials were characterized for its mechanical properties like tensile, bending and compression strength and compared with the existing wood chipboard. The test result obtained showed that the jute reinforced ...
