Archroma: new eco-avanced “indigo clone” solution

The producer of dyes and specialty chemicals Archroma Management LLC, Reinach/Switzerland, recently launched its new Diresul Smartdenim Blue, a liquid sulfur blue dye designed to mimic indigo, at the ITMA 2019 in Barcelona/Spain. The new product will be the core of the company’s Indigo Reflection, a coloration system that behaves like indigo, but with a comparatively more sustainable and efficient application process.
The new indigo-mimicking Diresul Smartdenim Blue is aniline-free and can be used in Archroma’s water-saving Advanced Denim technology. It is a liquid sulfur dye that behaves like liquid indigo in neutral-green blue tone and in the most common wash-down processes. It has better fastness to minimize back staining, and allows overall wash-downs much closer to actual indigo to be created, whilst avoiding greyish cast especially in bleaching with hypochlorite.
Diresul Smartdenim Blue can be applied in all the standard dyeing methods recommended for sulfur dyes, including pad-ox, pad-steam, exhaust, denim in all its variations (color denim, bottoming and topping of indigo), as well as in the Advanced Denim procedures (Denim-Ox, Pad-Sizing-Ox).

CHT Group breaks the €500 million sales mark in 2018

With a turnover of €513 million, the producer of specialty chemicals CHT Group, Tübingen/Germany,  achieved a 12% increase in sales in 2018.
The clear commitment to sustainability not only pays off in the form of awards and prizes, but also scores points in daily business life. With its sustainable core range and efficient and resource-saving process control, the group is a pioneer in the industry, particularly in the traditional textile chemicals sector.
Presently, the development focus is clearly on the circular economy. Together with industrial partners, the group has developed a biodegradable textile printing system which will soon be sold at the Lidl discount store. In the field of PET plastic recycling, concepts and products were developed that support the process from PET bottle to baby diaper.
In addition, the business development with textile dyes in 2018 made an unexpectedly strong contribution to sales, as the CHT Group was able to supply dye classes that were affected by a shortage of raw materials due a very good sourcing strategies.
The investment in silicone specialties in 2017, through the acquisition of the ICM Silicones Group, also paid off in 2018 in an extremely difficult market environment, even though the shortage of silicone raw materials on the world market led to extreme price increases while the demand remained high.
In terms of the result, the CHT Group was unable to meet expectations in 2018, in particular due to the raw material cost problems. For some raw material groups, massive cost increases of over 80% were recorded by mid-2018.
For 2019, because of political and economic risks, a rather moderate growth in sales is expected. Due to increasing trade conflicts, especially between the USA and China, the market development has not become easier.
The group is focusing on the strategic realignment of the Southeast Asia region which is now benefiting from the trade conflict.
In financial terms, the CHT Group has set itself the goal of continuing to grow profitably in 2019, and thus significantly increasing its result compared with the previous year.

Monforts: new system for multi-color yarn dyeing

At the ITMA 2019 from June 20-26, 2019, in Barcelona/Spain, the manufacturer of textile machinery A. Monforts Textilmaschinen GmbH & Co. KG, Mönchengladbach/Germany, introduced a new system for yarn dyeing based on the Econtrol dyeing system for fabrics. This CYD denim processing technology integrates new functions and processes into the weaving preparatory processes – spinning, direct beaming, warping and assembly beaming, followed by sizing and dyeing – in order to increase quality, flexibility, economic viability and productivity.
Econtrol is a pad-dry process employed in Monforts continuous dyeing in which the reactive dyestuff is fixed to the cellulose fibers during drying and the CYD multi-color yarn dyeing system introduces a number of new concepts based on it, including the unique Eco Bleach process. This is the first bleaching system for yarn treatment available on the market and will be of particular interest to denim manufacturers.
The Eco Bleach system is combined with the washing units and the fabric is then dyed immediately, resulting in considerable savings in waste water and chemicals. The most effective dyeing process for fabrics is now being applied for yarn dyeing and it is possible to process short batches of between 5-10,000 m of yarn in order to produce 2-300 m of fabrics in a single continuous process.

Monforts: new exhaust air treatment system

The manufacturer of textile machinery A. Monforts Textilmaschinen GmbH & Co. KG, Mönchengladbach/Germany, presented an energy-optimized new version of its Montex at the ITMA 2019 from June 20-26, 2019, in Barcelona/Spain. With the introduction of the new MonforClean exhaust air treatment system and other process innovations, Monforts has been able to further reduce the energy consumption of Montex stenters by a further 13%.
Exhaust air treatment on stenter frames has posed particular challenges over the years, since the air can contain significant amounts of oil, fiber and even wax particles that may see emissions limits being reached in the processing of certain fabrics, depending on the legal specifications. In addressing this issue, Monforts is now incorporating the MonforClean module into the stenter frame, so there is no additional space requirement. At the same time, the costs for laborious secondary installations and the piping of the exhaust air treatment components, as well as supporting structures are eliminated due to the machine configuration. The waste heat from the drying process is used to pre-heat the drying air, resulting in a radical reduction in the conventional heat supply required compared to gas and thermal oil heating. The further integration of an automatic exhaust air filter washing system automatically cleans the module elements, ensuring the consistent efficiency of both the filter and heat recovery modules. The modular MonforClean system is also available in different expansion stages and automates the heat recovery and exhaust air treatment, while eliminating odors and ensuring the exhaust air is highly purified before escaping into the atmosphere.

Karl Mayer: new eco-friendly indigo dyeing technology

At the ITMA in Barcelona/Spain from June 20-26, 2019, the textile machinery manufacturer Karl Mayer Textilmaschinenfabrik GmbH, Obertshausen/Germany, launched an eco-friendly indigo dyeing technology. Greendye, an innovative technology for producing jeans fabrics with minimal ecological footprint, opens up another market sector, Sustainable Denim.
The nitrogen technology ensures less environmental impact and more efficiency during indigo dyeing. With its high concentration in the dye bath and under nitrogen atmosphere, the dye diffuses and migrates more intensely into the fiber than in the case of conventional comparable procedures. The yarn can absorb 3 times more dye in a dye vat. In this way, it is possible to reduce the number and length of vats, with positive effects for the environment. The chemical consumption can be reduced considerably, a reduction of 50% is possible when using hydrosulfite and caustic soda, and there is also less yarn waste. Moreover, due to the good fixation of the dyestuff on the fiber, considerably less water is required during the washing process.
