CHT BEZAKTIV ONE
The New WOW of Dyeing

The new BEZAKTIV ONE range meets the highest demands in terms of ecology and sustainability and covers market and customer requirements that are placed on innovative dyes precisely and to the point – therefore they call it The New WOW of Dyeing.

BEZAKTIV ONE is the newest and most modern reactive dye range from CHT. The range covers a broad color spectrum with tinctorial very strong dyes. This enables a cost-efficient dye process with significantly less dye and salt. The excellent wash-off behavior allows short rinse cycles at lower temperatures and therefore offers further ecological and economic advantages. The dyes are particularly suitable for durable textiles due to their good multiple-wash fastness.

Cellulosic fibers are often dyed with reactive dyes, as these are commercially available in a wide range of colors that result in dyeing with high wash fastness. However, reactive dyeing requires a lot of water due to the necessary rinsing processes. Due to increased ecological requirements, the development of energy and water-saving processes is not just a trend, but rather a core prerequisite for new dyes.

A minimal number of rinsing baths and generally lower temperatures for dye exhaust, rinsing, and soaping contribute to overall efficient water and energy-saving dyeing process. This is exactly what the new BEZAKTIV ONE dyes are all about.

Overview of the advantages
• Economical and shortened dyeing, rinsing and soaping processes at temperatures between 40 and 60 °C.
• Good multiple wash fastnesses according to ISO 105-C09.
• Free of p-chloroaniline (below the detection limit of 5 ppm).
• High fixation speed.
• Very good washout/rinsing properties.


• Good color build-up.
• Excellent solubility.
• Suitable for all dyeing processes.
• Well combinable with each other.


• Good reproducibility.

Shortened dye process
BEZAKTIV ONE dyes can be dyed, rinsed and soaped between 40 and 60 °C. Therefore, the BEZAKTIV ONE exhaust dyeing process is significantly shorter compared to conventional reactive dyeing processes, where temperatures between 60 and 98 °C are required. This advantage means savings in process time and higher productivity for the textile dyer.

The advantages become particularly clear when dyeing medium to dark shades with the BEZAKTIV ONE process. Due to the high fixation level in combination with good color build-up dark shades can be matched with lower dye concentrations of BEZAKTIV ONE than with conventional bifunctional reactive dyes.

The addition of the auxiliary COTOBLANC SEL in the second soap bath has an additional positive effect so that a washing process with low water and energy consumption generates excellent wet fastness properties on the textile.

The BEZAKTIV ONE dyes are ideally suited for use in the well-known 4SUCCESS process: a perfectly coordinated process optimization for the discontinuous processing of cellulose fibers. The individual modules have proven themselves in practice and can be combined with each other like building blocks. With the perfect interaction of the individual processes, significant energy consumption can be reduced as well as water requirement, and shorten the processing time.
