PRATTELN, Switzerland — January 17, 2022 — Archroma, a global supplier of specialty chemicals towards sustainable solutions, and Jeanologia, a world supplier of sustainable and efficient technology development, joined forces to launch an eco-advanced alternative to the denim fabric washing process, including in some cases the mercerization, one of the most water-intensive and pollutant processes of denim fabric finishing.
The production of denim requires a succession of several steps aimed at imparting the qualities we love in our favorite pair of jeans.
It all starts with the spinning step where the cotton is turned into yarn. The second step is a pretreatment that will prepare the yarn for the dyeing step. The dyed yarn then goes through the sizing process, which is a treatment preparing it for weaving. At this stage, we have obtained a denim fabric that will go through a few more steps. First, the fabric may undergo a washing treatment or, in some cases, mercerizing treatment which consists of treating it with caustic soda in order to obtain a more lustrous, flat and less reddish blue and black denim.
In both traditional ways to clean the fabric, washing or mercerizing, multiple highly water intensive washings are required in order to restore optimal fabric pH and remove unfixed dyestuff and any undesired deposits or impurities from the fabric. One of such impurities released in the washing process is aniline, a substance that is classified as a category 2 carcinogen and considered toxic to aquatic life.
That is why Archroma and Jeanologia decided to team up and develop an alternative to the traditional fabric cleaning process and its subsequent water-intensive and water-polluting washings.
Jeanologia和Artroma提出的织物清洁概念的突破性替代方案结合了对Artroma的无苯胺*纯靛蓝偶像染色系统的使用，以及无水**和无化学的“ G2动态”珍妮拉洛尼亚的固定技术。
Artroma Pure Indigo图标是基于该公司于2018年5月发起的一项创新：无苯胺*Denisol®纯靛蓝。苯胺是制造靛蓝分子的关键要素。不幸的是，在此过程中，一些苯胺杂质被带入靛蓝染料。当靛蓝被染成织物上时，许多苯胺杂质被锁定在织物中的颜料中。染色期间，每年约300公吨的苯胺杂质的其余部分被排出。这可能是一个问题，因为苯胺对水生生物有毒。此外，对工厂工人的接触水平可能很高。因此，新的Denisol Pure Indigo 30 Liq被开发为无苯胺（1）靛蓝解决方案，适用于渴望真实的靛蓝灵感的设计师，制造商和品牌所有者。
Jeanologia G2 Dynamic于2008年推出。连续织物的市场优先处理大大减少了所使用的水和化学物质的量，同时又减少了磨坊的节省成本，并最终在服装装修设施中节省了成本。这项技术使织物更稳定和一致，并为使用其他技术（如激光器）做好了更好的准备。正如几个月前与Artroma合作提出的那样，该机械可与PAD-OX技术一起使用，以帮助清洁织物，从而在室温下，可在能源和CO2上节省大量资金。
The Archroma/Jeanologia solution allows to create aniline-free* denim, and improve the final aspect of the fabric through a fully chemical-free and almost water-free** cleaning alternative treatment.

Umberto Devita, Business Development manager at Archroma’s Competence Center for Denim & Casual Wear, who was the project leader for this new development, commented: “At Archroma, we strive to develop solutions in line with our principles of “The Archroma Way to a Sustainable World: Safe, efficient, enhanced, it’s our nature”. It was therefore very inspiring to work with a partner who shares the same values of developing efficient new processes to bring all know-how to our customers to maximize value – for denim that looks as good as the good it creates.”
For Jean-Pierre Inchauspe, Business director of G2 Dynamic at Jeanologia: “this association is another step to change traditional, more polluting and water consuming processes in the textile industry for new ones using technology, improving, and boosting subsequent production stages up to the finishing of the garment, making them more efficient and allowing companies to be more competitive, increase productivity and offer a product that is completely sustainable with high quality.”
