Archroma and COLOURizd™ collaborate to make fashion more sustainable

Archroma, a leader in specialty chemicals towards sustainable solutions, is teaming up with COLOURizd™, an innovator specializing in sustainable textile dyeing technologies, to set a new standard for the eco-friendlier production of sustainable textiles.

The new collaboration will enable fabric mills and brands to combine Archroma pigment coloration solutions with the COLOURizd™ QuantumCOLOUR™ yarn-coloring technology to produce high-quality, high-performance textiles with maximum consumer appeal and minimal environmental impact.

Conventional fiber-reactive methods of dyeing cellulosic and synthetic yarns are multi-step resource-intensive processes that use up to 95 liters of water per kilograms of colored yarn and discharge approximately 94 liters of effluent.

Conventional fiber-reactive methods of dyeing cellulosic and synthetic yarns are multi-step resource-intensive processes that use up to 95 liters of water per kilograms of colored yarn and discharge approximately 94 liters of effluent.

In contrast, the innovative QuantumCOLOUR™ process injects pigment and a binder directly into the yarn, using only 0.95 liters of water per kilograms of colored yarn while producing zero effluent. This represents an unprecedented reduction of 98% in water consumption alongside zero wastewater discharge, zero discharge of harmful chemicals, 73% decrease in carbon footprint and 50% reduction in energy use.*

With Archroma, textile manufacturers and apparel brands can add further value to the QuantumCOLOUR™ process with tailor-made system solutions, including JUST COLOR. This formaldehyde-free** pigment coloration system is based on Archroma’s revolutionary Printofix® pigment dispersions and Helizarin® binders to deliver exceptionally soft fabrics with high fastness and durability, while also enabling energy and chemical savings and higher productivity.

BEZAKTIV ONE: New Reactive dyes range by CHT

  • Reactive dyes for water and energy saving dye processes with significantly shortened process time

BEZAKTIV ONE 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 dyeings with high wash fastness. However, reactive dyeings require 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 an overall efficient water and energy saving dyeing processes.

A minimal number of rinsing baths and generally lower temperatures for dye exhaust, rinsing and soaping contribute to an overall efficient water and energy saving dyeing processes.

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.

Asahi Kasei renews membership by the United Nations BCtA programme

Asahi Kasei's ongoing commitment to strengthen the Bemberg™ fibre value chain from raw materials to final products textile industry and support local people, institutes, and the environment, has been recognized by the United Nations BCtA programme, who has renewed its membership for India. Starting from the company and including the material, Bemberg™ integrates new generations of values such as innovation and responsibility together with design. This important breakthrough showcases how the smart fibre is globally recognized for its innovation, responsibility and ability to deliver high-quality and sustainable ingredients at the same time committed to support the Sustainable Development Goals (SDGs).

Objectives of this initiative include:

Objectives of this initiative include:  

  • By 2023, enhance skills of 1,671 employees in the Bemberg fiber industry and advance production efficiency of 55 small to medium scale de-linting, weaving and dyeing manufacturers, through employee training, capital investment and technical support.
  • By 2023, develop capacity of 575 young people, especially women, who will lead the Indian textile industry, by providing vocational training opportunities and institutional support for the three schools.
  • By 2023 cumulative amount of 40,000m3/day textile dyeing effluent will be treated and recycled back to their own textile dyeing process, which is equivalent to saving daily water access to natural water resources for approx. 25,000 households.
