BEZAFAST ES – THE NEW WAY TO GO IN CONTINUOUS DYEING

The growing demands of the fashion and textile industry, and a constantly increasing consumer awareness, call for chemical products and process aids which are simple to use while still being efficient and environ-mentally friendly.

Continuous processes have been developed for large quantities and are therefore only profitable and productive from a length of several thousand metres. They also require both very high investment costs and a well planned and functioning infrastructure in-cluding optimum machine maintenance – as otherwise the costs would quickly explode.

The new BEZAFAST ES process offers a fundamentally new opportunity for dyeing light shades on 100 % cellulosic woven fabric and its blends with polyester. This ad-vanced process is made possible by the spe-cial combination of the newly developed BEZAFAST ES dyes and the unique auxiliary system. This innovative system considerably reduces the equipment required and the high consumption of chemicals.

THE NEW BEZAFAST ES PROCESS – FOUR «E»s FOR YOUR SUCCESS

EASY – the easiest and shortest route in continuous dyeing

ECONOMICAL – the most economical way to perform continuous dyeing applications

EFFICIENT – the highest productivity, guaranteed

EXCELLENT – for soft handle, has a low equipment requirement and high light and washing fastness

The BEZAFAST ES system is particularly suitable for use for: Home textiles (e.g. bed and table linen,

curtains, furniture fabrics) Shirt fabrics Ground dyeings for printing Over-dyeing of denim fabrics Shading of vat or reactive-dyed fabrics

BEZAFAST Yellow ES liq. Neutral yellow with high light fastness properties, no catalytic fading

BEZAFAST Red ES liq. Especially for all shades of pink and as a shading component

BEZAFAST Blue ES liq. Combination dye with the highest level of light fastness

BEZAFAST Green ES liq. Ideal for brilliant shades of green, also in combination with BEZAFAST Yellow ES liq.

BEZAFAST Grey ES liq. Especially suitable for grey shades with a high light and wet fastness level, or as a shading component

ARRISTAN ES Multi-functional product developed especially for the BEZAFAST ES process. It guarantees the optimum fixation of the liquid dyes used under the described conditions.

MIGRASOL ES Provides an antimigrant property during pad dyeing and prevents the migration of colour pigments when drying.

KOLLASOL CDS Deaerator and penetration accelerator with excellent foam-inhibiting properties.

PADICOLL DYE Padding auxiliary prevents the formation of deposite on roller.

THE BEZAFAST ES SYSTEM

The BEZAFAST ES process is suitable for use on conventional continuous dyeing ranges (e.g. Hotflues):

However, it is equally suitable for use on stenter frames with controlled air circulation:

ECOLOGICAL INDICATORS

WATER CONSUMPTION

In a Pad Dry Pad Steam process with vat dyes (length 2000 m): approx. 8000 lWhen dyeing with BEZAFAST ES (length 2000 m): approx. 500 l

TOTAL DISSOLVED SOLIDS

In a Pad Dry Pad Steam process with vat dyes (length 2000 m): approx. 55 kgWhen dyeing with BEZAFAST ES (length 2000 m): approx. 3 kg

CARBON DIOXIDE EMISSION

In a Pad Dry Pad Steam process with vat dyes (length 2000 m): approx. 840 kg CO2

When dyeing with BEZAFAST ES (length 2000 m): approx. 400 kg CO2

Continuous dyeing processes consume large amounts of different energy resources, for example for IR-drying, thermofixing, steaming and washing processes. The new BEZAFAST ES process fundamentally changes these previous continuous dyeing conditions.
