New Equipment for Pad-Dry Dyeing.

Benninger's hot flue pad dry dyeing machines provide highly reliable dyeing with low maintenance costs and environmental friendliness. The range allows for the continuous in-line operation of both pad dry and pad-steam dyeing. Machine design includes a fabric feeder, padder, air passages, infrared predrying, hot flue, cooling cylinders, e..

The Use of a Crosslinking Agent to Achieve Covalent Fixation of Hydroxyethylsulphone Dyes on Cotton.

Research on dyeing woven cotton fabric used hydroxyethylsulfone dyes and a tetrafunctional crosslinking agent to achieve covalent fixation. The tetrafunctional crosslinking agent was N,N'-bis(dichloro-s-triazinyl) 4,4'-diaminostilbene 2,2'-disodiodisulfonate (T-DAS), which contained two highly reactive dichloro-s-triazine residues and two..

New generation of monitoring systems for the textile industry

The PCMs (Personal Computer Monitoring System) from Barco automation, Belgium, is based on a client-server concept with a Windows NT server and a network of Windows-based clients (95 or MT). The most important real-time analysis tool is the Mill, a colour-coded layout of the production floor showing all the machines which are colour-coded..

Quality assurance and reduction in costs by process control

This article features two papers which were presented at the Dyers Conference which was held in Bad Salzuflen, Germany in 1998. The first paper deals with the factors that influence quality in the dyehouse, it is titled how can quality assurance be taken into account in modern dyehouses? and was written by R. Adrion. The second paper is a..

Color resist style on wool/natural silk blended fabric using reactive dyes

A colored-resist style could be achieved by including in the printing paste an illuminating dyestuff that is fixed in the presence of a resist agent. The illuminating color is monochlorodifluoro pyrimidine. The ground shade is printed wet-on-wet with viny sulphone dye, (pH 1-2). After moderate during the printed area is steamed for 10 min..

Ultrasonics in wool dyeing - ready for practical application?

A study was carried out to compare conventional dyeing to the ultrasonics method of operation by dyeing wool fabric with two acid dyes of different molecular size, Telon Red AFG and Supranol Blue RLW, in a laboratory dyeing machine. The use of ultrasonics is discussed in detail, together with aspects of economics and energy expenditure fo..

Knitted fabrics: considerations (Italian) (Tessuti a maglia: considerazioni)

The dyeing of knitted fabrics is discussed, with particular reference to improving the prospects of the dyeing industry. Among the possible ways of doing this: a recovery of consumption; increased demand from developing countries; reducing labour costs modifying the means of transporting the dyes, the author considers the only remaining w..

Process automation - the key to wastewater recyling and water and energy conservation

The application of process control automation software for the recycle of peroxide bleaching rinse water to fabric scouring on a continuous preparation range is presented. analytical data taken on wastewater samples document operating conditions of the preparation range and the quality of the recycle water. An economic analysis of the rec..

New methods for treating textile finishing effluents

Following an outline of the problems faced by the textile finishing industry due to the high effluent level and a review of conventional effluent treatment technologies, the development of some new methods is described. These include the use of modified biofilters and ozonisation, the re-use of concentrated residual liquors from chemical ..

Real Time Analysis and Control of Batch Dyeing Processes.

Researchers developed systems for dyebath monitoring, neural network and fuzzy logic control, color matching algorithms, and closed loop dye and chemical dosing. Spectrophotometric methods monitored the exhaustion of vat dyes, whereas a flow injection analysis system monitored reactive and direct dyeing of cotton, basic dyeing of acrylic,..
