Use of ion-exchange absorbers for removing detergents from laundry effluents

The use of five ion-exchange absorbers for recovering four different detergents from laundry effluents is discussed.

Ecological demands on dyeing systems

In the past dyeing systems were selected according to technical (fastness properties and colour yield) and economic (price/strength ratio) criteria. New criteria which have been adopted are the quality system and the competence of the supplier. Particular emphasis is laid on ecological and toxicological properties. An explanation is given..

Application of the ozone treatment to the purification of textile wastewater

The ozone treatment of various textile effluents, including dyeing and laundry effluents, is examined. The elimination of some toxic impurities is considered.

Textile Effluent Treatment: The Spiral Membrane Advantage.

Desalination Systems Incorporated, a leading manufacturer of filters and filtration systems for the textile industry, recently introduced the Desal-5. The Desal-5 is a spirally wound nanofilter membrane for the decolorization of waste effluent from finishing plants and dyehouses. It removes soluble dyes, dyeing and finishing auxiliaries, ..

A New System of 'Microwash' Rinsing Developed by Sclavos SA.

The firm Sclavos SA announced the launch of a new option on its Apollon Twin flow soft dyeing machine. Conscious of growing demands imposed on fabric dyers to reduce the consumption of water, both to cut down on costs as well a to respond to the new global consciousness for environmental protection, the company disigned Microwash, a speci..

Ozone Can Help in Dyeing.

Ozone treatment of dyehouse effluents is helpful for removing color from the wastewater after the completion of biological treatments. Under suitable operating conditions, ozone also acts as a powerful oxidizer that reduces the total organic carbon content (TOC) in organic pollutants. Experiments conducted in a laboratory confirmed the TO..

Thies: New Eco-Soft Plus Rapid Dyeing Machine

Thies' Eco-Soft rapid dyeing machine is available in both single and double rope models for dyeing knit and woven fabrics. The machine incorporates up to eight chambers that dye at temperatures of 95, 103, or 140 degrees centigrade. The positioning of the reversing winch and an improved nozzle design ensure gentle fabric treatment. The fi..

Economical and Ecological Dyeing with an Aerodynamic Dyeing System.

Then's aerodynamic dyeing system propels fabrics with a flow of moist air or with a flow of air that contains saturated steam. These dyeing machines inject dyes, chemicals, and auxiliaries directly into the air stream. This injection system evenly distributes the atomized bath liquors onto the fabric surface and optimizes liquor penetrati..

Dyeing Pad Control by Dye Measuring.

Preliminary trials at the Kusters development laboratories measured the dye content in wet fabrics behind the pad nip and used this information to control the pressure of the dyeing pads. Objective trials attempted to reduce dyeing faults caused by uneven pad pressure. The moisture measuring device used microwaves to penetrate the fabric ..

Dyeing, Drying, and Tumbling.

Krantz has added a drying/tumbling capability to its Aero-Dye piece dyeing machine with the development of two differently equipped variants: one for tumbling and one for drying and tumbling. Because the auxiliary capabilities do not alter the design of the Aero-Dye machine, the drying and tumbling options can be retrofitted to existing m..
