1.1 Dyeing auxiliaries Auxiliaries are compounds which are not an integral part of the dyeing process but by adding them to the dye bath the dyeing can be improved. The main functions of auxiliaries are to prepare or improve the substrate in readiness for colorants (by wetting, providing sorption sites, improving or resisting the migration of dyes), to stabilize the application media (by improv...

The role of sawdust in the removal of pollutants from textile wastewater has been investigated. The textile wastewater was treated by using sawdust as adsorbent and then filtered. The various physicochemical characteristics of sawdust treated and untreated textile effluent were analyzed. The maximum percent removal of 37% was observed for total suspended solids while minimum removal of 9% for c...

In this paper we show how we have applied, in a current project, mobile agent technology to an industrial process in the field of textile manufacturing. The project involves several companies, each of which is a Europe-wide representative of one of the key phases of the textile production process (e.g. spinning, weaving, dyeing, finishing and ready made clothing). The main contribution of this ...

Wastewater discharge from textile industries concern environmental risks. Superiority of microbial methods over other high cost combined includes conversion persistent organic materials to non-toxic last materials, sustainability, low cost, and comfortable. Textile wastewaters can have opposite effects on the quality water in total carbon (TOC) Chemical oxygen demand (COD). Agitation cultures r...

The domestic use and industrial activity, especially in developing countries, produce large amount of wastewater. This wastewater when disposed into natural channels may lead to high pollution risk. There are different methods for wastewater treatment. One of them is Advanced Oxidation Processes (AOPs), still it has some limitations. The present work has been concentrated on the degradation of ...

Natural dyes have been used from ancient times for multiple purposes, most importantly in the field of textile dying. The increasing demand and excessive costs natural dye extraction engendered discovery synthetic petrochemical compounds. Nowadays, they are dominating market, with nearly 8 × 105 tons produced per year due to their wide range color pigments consistent coloration. Textile industr...

The present study is an attempt to isolate and optimize the fermentation conditions of three fungus, namely Trichoderma virens, Alternaria alternata and Curvularia lunata to get pigments for the purpose of textile dyeing. Highest optical density has been achieved in potato dextrose broth at 28oC in 25 days under static conditions. Wool and silk are dyed unmordanted with very good wash and rub f...

One of the major problems encountered in the textile industry is the production of large volumes of highly coloured wastewater. The textile industries daily discharge million litres of untreated effluents in the form of wastewater into public drains that eventually empty into rivers. They cause serious health hazard. Textile wastewater also contains substantial pollution loads which increase th...

aims: several methods have been used for textile wastewater treatment. the aim of this study was to evaluate the efficiency of rosa damascena watering waste ash for cod and color removal from textile wastewater.  materials & methods: rose watering waste was gathered from one of the kashan processing plants. the raw wastewater sample was taken from one of the textile industries in kashan country...

BACKGROUND Fungal manganese peroxidases (MnPs) have great potential as bio-remediating agents and can be used continuously in the immobilized form like many other enzymes. RESULTS In the present study, purified manganese peroxidase (MnP) enzyme isolated from Ganoderma lucidum IBL-05 was immobilized onto polyvinyl alcohol-alginate beads and investigated its potential for the decolorization and...
