Chemical technology for a better tomorrowADDRESSING WATER SCARCITY

Governments are closely monitoring the situation. Water scarcity and, as a consequence, water pollution have shown dramatic consequences for local populations in production countries, such as China and India. Authorities in those countries are taking strict measures to ensure cleaner production by local textile mills or laundries, such as water treatment facilities or setting tight load limits in water effluents.

Global awareness about water scarcity has considerably increased in recent years among the general public, with actions conducted by NGOs or inter-national institutions such as the United Nations with the World Water Day on 22 March 2013.

With its DETOX campaign started in July 2011, Greenpeace has brought the topic to the attention of consumers, notably leading major apparel brands and retailers to commit to the so-called Joint Roadmap to Zero Discharge of Hazardous Chemicals. Reducing water pollution is of course one area of action, and Clariant is playing its part with our constant stream of dyes and chemicals innovations.

But a lot can be done in water consumption per se. Major apparel and outdoor brands and retailers are showing strong interest in processes and solutions that allow tackling the problem at its source: reducing water consumption during textile production.

Clariant, with our firm commitment towards “sustainability by innovation”, has introduced in recent years a number of innovative solutions that can be easily adopted by textile mills and manufacturers willing to answer the growing demands for reduced water consumption by brands and retailers.

And with our new ONE WAY sustainability service launched in October 2012, Clariant can help textile mills demonstrate, with transparent and reliable facts and measurements in hands, how new available technologies help answer the brands’ and retailers’ requirements for more sustainability – at controlled cost levels.

Read through the following pages to discover our chemical solutions for reduced water consumption – because each drop counts.

The production of denim fabric usually involves huge quantities of water. This is a problem Clariant practically solves with its groundbreaking Advanced Denim technology, which simplifies the finishing and dyeing of a fabric that accounts for some 14% of global cotton production.

Based on Clariant’s Denim-Ox and Pad/Sizing Ox, the two core innovative processes introduced under our Advanced Denim concept, the idea consists of replacing indigo dyes with Diresul® RDT sulfur dyes in the dyeing process in combination with Arkofil® DEN-FIX sizing agents. The Advanced Denim dyeing processes can cut the number of dyeing vats from 15 in conventional indigo-based dyeing down to 1 (one!).

In total, when employing the Clariant’s Advanced Denim processes, Denim-Ox and Pad/Sizing Ox, water consumption can be reduced by up to 92%, while up to 63% of the usual cotton waste can be avoided. Plus, up to 30% can be saved in energy costs compared to traditional denim processes.

SAvINGS Potential

The use of Clariant’s Advanced Denim technology allowed savings of ~ 700 million liters of water in 2012. Clariant’s Advanced Denim was used only in an extremely small part of the worldwide production of jeans. Imagine how much water could be saved if more manufacturers joined the Advanced Denim revolution!

But there is more. For over a century, the principle dyes used in the production of standard blue denims were indigo based, which restricted the palette of colors available to manufacturers. Clariant sets a new benchmark with its Diresul® RDT “Indicolor” dyes, opening the door to an infinite range of shades and hues: arctic night, blue sky, dark sea, earthy tones, greens and a full range of colors inspired by and created for nature. Together with blues, navies, grays and blacks, they enhance denim’s look and feel, add a vast range of new shades and wash-down effects, and create smart finishes.

Colors other than blue have been in the past trickier to achieve but with Diresul® RDT dyes in combination with the Denim-Ox and Pad/Sizing Ox processes used in the Advanced Denim technology, it is much easier. The process is simple to control, more effi cient and suitable for small batches. Advanced Denim makes it very simple to rapidly respond to changing demands from the market. Clariant’s full range of Diresul® RDT sulfur dyes allow unique eff ects, better reproducibility of tones and shades as well as more precise results to be achieved – without making any changes to existing production lines.

Compared with conventional denim production, Clariant’s unmatched Advanced Denim technology is simpler, more versatile, and opens the doorway to undreamt-of opportunities. And when it comes to environmental compatibility, Clariant’s trail-blazing new technology raises the bar to a whole new level.

Awarded technology, certifi ed environmental benefi tsAdvanced Denim technology has been honored by two of the prestigious 2012 Innovation Awards organized by ICIS Chemical Business magazine. Not only was the Advanced Denim breakthrough eco-advanced dyeing technology recognized by the jury as “Innovation with Best Environmental Benefi t”, but it was also judged as the year’s overall winner.

In addition, Clariant was one of the fi rst companies to be awarded an EU Ecolabel* for its illustration collection of jeans in recognition with the sustainability benefi ts of Advanced Denim. The EU Ecolabel, also known as the “EU Flower label”, is considered one of the highest certifi cations, acknowledging that all stages in the production of a fi nished article have met the EU’s stringent environmental protocols.

ClARIANT’S ONE WAY SCORE CARDClariant’s SWIFT continuous dyeing process for PES/CEL, compared to conventional process

Continuous dyeing of polyester/cellulose (PES/CEL) woven fabrics is another example of a process that can be extremely resource intensive. Established methods for dyeing such blends require high amounts of water, as well as energy and chemicals.

Clariant therefore developed the new so-called “SWIFT” continuous dyeing process for PES/CEL blends using the innovative Foron® S-WF disperse dyes together with the high performing Drimaren® HF-CD specialty reactive dyes for continuous application. A little bit of Clariant’s SWIFT process for dyeing PES/CEL woven fabrics represents a lot: an innovative solution for dyeing all depths of shades, which minimizes the environmental impact by meeting industry demands for shorter and economical processes that save water and energy.

SWIFT process allows considerable water savings.

A one-bath, two-stage process for dyeing PES/CEL with alkali clearable Foron® S-WF disperse and Drimaren® HF reactive dyes where high wash fastness is achieved without a reduction clearing step.

The disperse and reactive dyes are padded together, and the whole process can be completed with one pass through a continuous dyeing range. The SWIFT continuous dyeing process for PES/CEL can dye fabrics at all depths of shade, reducing water and energy consumption while increasing productivity.

SAvINGS Potential

The swift process allows up to 50% water savings compared to conventional continuous dyeing process for PES/CEL fabrics using disperse and reactive dyes.

In the established process for continuous dyeing PES/CEL fabric, a polyester/cellulose fabric is most commonly dyed using a combination of either disperse/vat dyes or disperse/reactive dyes.

The polyester portion of the blend is dyed with disperse dyes by a pad-dry-thermosol procedure, whereas the cotton portion is dyed with either vat or reactive dyes by a chemical pad steam process.

In the case of vat dyes, a reductive steaming (caustic/hydros) step is necessary to convert the dye to its soluble form so that it can diffuse inside the cotton fiber. At the same time, this acts as a reduction clearing process by removing any unfixed disperse dye from the polyester fiber surface, ensuring that a high fastness level is achieved.

This reduction clearing step means that the fabric must be passed twice through the continuous dyeing range. This has a high impact on energy and water consumption together with productivity, labor and effluent treatment costs.

Let’s pour water in a glass, not in a tee-shirtUlTRA lOW lIQUOR RATIO CEllUlOSIC DYEING

Preparation, dyeing and finishing of cotton substrates have utmost water, energy and chemical requirements and therefore offer high possibilities for savings. Reduction in the amount of water used is a particular focus because it brings corresponding reductions in the energy required to heat water and, to a lesser extent, the amount of dyes and chemicals used.

In the past few years, new types of jet dyeing machines have been introduced which can dye cotton at an ultra low liquor ratio (ULLR) of 4:1 – 6:1. For cotton processing, the liquor ratio can be reduced from 8:1 to 4:1, allowing reduced fabric tension and friction for better fabric running conditions in the chamber, shorter processing times (e.g. faster loading/unloading, heating/cooling, filling/draining) and reduced water, energy and chemical consumption.

Add to that the right dyes, Clariant’s Drimaren® HF range, and textile manufacturers are in the position to achieve vast savings in water, energy and chemical consumption, and reduce the environmental footprint of the textile produced.

When dyeing at low liquor ratio, Clariant’s Drimaren® HF reactive dyes display high neutral substantivity combined with very good migration/leveling in the salt phase and a high degree of fixation close to the exhaustion value after the alkaline step guarantees high shade reproducibility. Lower salt requirements help save water as the number of rinsing baths can be reduced. And the low substantivity of the unfixed dye, combined with very good diffusion, guarantees optimum washing off performance. This saves time and energy as high wet fastness is achieved after only four rinsing baths at a temperature of 60ºC.

SAvINGS Potential

With Clariant’s Drimaren® HF reactive dyes used in ultra low liquor ratio dyeing process, water consumption can be reduced by 25% compared to traditional processes.

Clariant does not only focus on developing water saving solutions for its customers; we also take at heart to reduce our own impact on water usage. In May 2012, Clariant started operating what we believe is the first-ever sustainable effluent treatment (SET) facility for a textile operational site in Jamshoro, Pakistan.

With an investment of USD4.0 million, the SET facility not only supports the substantial saving of 80 percent of water by recycling and reusing, but also allows effluent treatment based on zero liquid discharge fulfilling the very stringent Pakistan’s National Environmental Quality Standards (NEQS) requirements.

The Jamshoro site is one of the biggest textile chemical sites within Clariant. It produces dyes, chemicals, emulsions and pigment dispersions. The SET facility is a clear sign that we are constantly aiming for ever more sustainable solutions.

The operational SET plant is spread over an area of 25 acres consisting of primary, secondary and tertiary treatment to yield colorless water with a COD (Chemical Oxygen Demand) less than 75 ppm, BOD (Biological Oxygen Demand) below 20 ppm and TDS (Total Dissolved Solids) below 250 ppm.
