Reduction of effluent pollution in textile printing by production integrated measures. I

This article presents a number of production-integrated measures to permit a combination of ecology with economy. The measures are determined from the results of a survey of the mass flow conditions of a textile printworks.

The decolorization of textile effluent by the formation of a dye-including compound. VI.Investigation of industrial effluents and for regenerating the complex former

The decolorizing of dyeing effluents by complexing the dye molecules with the ligand cucubituril is studied. An almost quantitative removal of the dyes from the effluent is possible even if textile auxiliaries are present. In most cases the chemical oxygen demand is not affected by the decolorizing. Ligand regeneration by oxidative degrad..

A vacuum arrangement for draining yarn packages after dyeing is claimed. IPC F26B.

Process for dyeing or printing hydroxylgroup-containing fibre materials

A process for dyeing or printing a hydroxyl-group-containing fibre material comprises applying a trichromatic mixture of dyes of specified type to the fibre material. The blue dye is a sulphonated azo or azo copper complex dye and the red dye is a sulphonated azo copper complex dye. The composition of the yellow or orange dye is claimed. ..

Non-aqueous polyamide dyeing process utilizing controlled dye addition

A process for dyeing an article containing nylon fibres with an anionic dye comprises: immersing the article in a liquid dyebath containing a non-aqueous solvent medium; heating the dyebath; adding the anionic dye to the dyebath at a rate of about 0.0005 to 0.5％ dye/min based on the weight of the article; and stirring the dyebath to caus..

Wool dyeing process microlevelness and high standard of wetfastness

This article studies the dyeing of wool with newly designed wool dyes Acidol KM, based on 1:2 metal complexes and Acidol KW, metal free brightening components for Acidol KM dyes. The dyeing process for untreated wool, machine-washable wool and oxidized wool are described.

Blow-dye world premiere

A new Krantz dyeing machine known as the Blow-Dye is described. The machine combines the advantages of the classic winch beck with the components of modern dyeing machines and can be used for all tubular goods which do not require an HT system. The prototype has gone into production with the Turkish firm Cemtas in Istanbul. Its main featu..
