From the Sector

Archroma, a global leader in color and specialty chemicals, has presented an aniline-free* denim indigo dye at the recent Planet Textiles 2018 Conference in Vancouver, Canada. The brand new dye provides a non-toxic way to produce the traditional, iconic indigo blue that consumers associate with denim and jeans.
Currently, aniline impurities are an unavoidable element of producing indigo-dyed denim. Unlike other chemical impurities, aniline is locked into the indigo pigment during the dyeing process and therefore cannot be washed off the fabric.

Scientific testing has shown that aniline impurities are toxic to humans, causing skin allergies, damage to major organs and genetic defects, as well as being linked to cancer. Aniline is also toxic to aquatic life, which is an issue as two thirds of the 400 metric tons of aniline waste on an annual basis ends up in the environment as wastewater discharge. The toxic chemical is therefore starting to feature on the restricted substance lists (RSL) of some major clothing brands and retailers. “We have tested denim garments and found that aniline concentrations are frequently higher than expected,” says Alexander Wessels, CEO, Archroma. “This could put some manufacturers over the limits agreed on their RSLs.”

True to its commitment to take on innovation challenges, Archroma decided to take a closer look at the issue with its R&D experts, and developed an alternative system that is aniline free*.
“At Archroma, we continuously challenge the status quo in the deep belief that we can make our industry sustainable,” continues Alexander Wessels. “By removing a hazardous impurity from the denim supply chain, we aim to protect the workers who create denim, the consumers who wear denim, and the environment with cleaner waterways.” The Denisol® Pure Indigo 30 dye is the latest in a long line of sustainable innovations for denim started in 2009. That year, Archroma introduced its ‘Advanced Denim’ technology which uses up to 90% less water during the dyeing process. “Being not indigo but sulfur based, ‘Advanced Denim’ itself was an aniline free solution too!”, adds Alexander Wessels. For designers and brand owners who long for authentic indigo inspiration, the new Denisol® Pure Indigo 30 now also makes it possible to produce indigo-dyed denim without high levels aniline impurities. Archroma successfully tested Denisol® Pure Indigo 30 at Absolute Denim mill in Thailand. “During the testing everything performed exactly the same as it would with conventional indigo,” says Vichai Phromvanich, Board Member, Absolute Denim. “There was just one important difference: no aniline.”

“We’ve had an overwhelming positive reaction from the industry in sneak previews and during the launch at Planet Textiles,” continues Alexander Wessels. “As a responsible industry leader, we believe it’s important to actively look for eco-advanced solutions that are attractive and at the same time cost-efficient for clothing brands, retailers and end-consumers.”

Archroma will make the Denisol® Pure Indigo 30 dye in the most sustainable way as possible. The new dye will be produced in Archroma’s facility in Pakistan, a plant that made the headlines in 2012 for being what Archroma believed to be the industry’s first zero liquid discharge plant.

• Innovative Textile Processes

Innovations are welcome. Based on innovations, many changes in textile processing are leading to more efficiency in process workflows. At the International Cotton Conference in Bremen on Wednesday, March 21st, Session IV Textile Processing, which takes place from 4:00 pm to 6:00 pm, is dedicated to this subject area and attractive examples.

Sustainable
Michael Tuschak, Mayer & Cie., Germany, informs about the 3-in-1 concept of Spinitsystems. Spinning, cleaning and knitting are all combined in one machine. This enables the production process of high-quality single jersey knitwear to be shortened significantly, which saves energy costs and reduces CO2 emissions.

Indigo.
An old dye returns to glory. Dr. Dean Etheridge of Texas Tech University, USA, talks about a new, innovative indigo dyeing process for cotton yarns using foam. This saves large amounts of water and is now increasingly being used by major brands in jeans production.

Efficient.
Amin Leder, Trützschler GmbH & Co. KG, Germany, presents a technique in which the stretching process for rotor yarn production does not take place in a separate machine, but is integrated into the carding. This makes it possible to efficiently process even cotton with a higher waste content.

Overview.
Harald Schwippel, from Rieter, Switzerland, summarises all four major spinning technologies for cotton – ring spinning, compact spinning, rotor spinning and air-jet spinning. His talk provides an overview of the possibilities that each of these processes currently offers for the manufacture of different yarns and the most efficient options for different applications.

More to know
In the run-up to the International Cotton Conference, the Fibre Institute Bremen and the Cotton Exchange are organising a specific seminar for spinning mills on Tuesday, dealing with the efficient handling of contaminants in cotton, from elimination in production to removal in winding. On Friday morning, Expert Session IX deals with the exchange of the latest research results, e.g. in the field of ginning in relation to cotton quality, or the important issue of checking the traceability of GMO-free cotton.

As the global textile industry’s most comprehensive sourcing summit for the spring / summer season, Intertextile Shanghai Apparel Fabrics is naturally the ideal place to find the latest developments in product innovation and sustainability. This is especially true in the fair’s Beyond Denim zone, which this edition will feature over 110 exhibitors from China, Japan, Pakistan, Turkey and elsewhere. Adding to a total of some 3,300 exhibitors from around 22 countries and regions, they provide sourcing options for the entire industry, from fabrics for ladieswear, menswear, suiting, shirting, lingerie and swimwear to high-end wool fabrics, original pattern designs, functional & performance fabrics, sustainability products & services, digital printing technologies, garment & fashion accessories and more.

Denim enriched with volcanic ash: the latest innovation from Orta Anadolu
Volcanic ash is not uncommon in beauty products – it is known as Mother Nature’s skin purifier after all, and used as an exfoliator for example – but it is far less common in the textile industry. Orta Anadolu are set to change that with their BIOWARE denim which is enriched with mineralised volcanic ash to create an odour absorbing effect. This technology captures and absorbs odour compounds that would normally pass through the fabric, neutralising bad bacteria while retaining the helpful bacteria that common deodorisers, which contain harsh substances, normally eliminate. This leads to a more environmentally friendly product that is better for the user’s skin.

Orta will also be presenting BIOCHARGE at Intertextile, which, according to the company, is the world’s first denim fabric for muscle wellness. Infused with minerals, Orta state that BIOCHARGE is medically proven to refresh muscles, relieve muscle tension and optimise body balance. They will also present their BOUNCE stretch range, with high elasticity and a ‘street’ style, while CHRONICLE, another in their S/S 19 range, is a blend of heritage and future styles.

US Denim Mills blend tomorrow’s technology with yesterday’s style
Another innovative denim firm exhibiting at Intertextile Shanghai, and another blending old and new, is US Denim Mills. According to the company, their collection at the fair will “harness tomorrow’s textile advances to revitalise the great style visions of the past by adding fashion, comfort, performance and sustainability advantages to authentic denim looks.” This collection includes:

• Selvedge: using the company’s legacy selvedge looms to produce bi-stretch ‘SelvedgeX’ while experimenting with blends of natural yarns and high-tech fibre blends in its ‘HeritEdge+’ range
• Stretch: including ‘Flex 360’ bi-stretch denim with a slight cross-bias freedom, and ‘Modern Stretches’ with a higher stretch range for intense comfort
• SoftWear: advanced finishing treatments for superior soft touch from natural fibre blended yarns and softness-selected weaves
• Sustainable: new additions to the range of recycled and natural ‘GreenEgo’ denims

Kipas Denim step up their sustainability efforts
Well aware of the effect denim production has on the environment, Kipas Denim’s multi-faceted programme to address this is one of the most comprehensive in the denim sector. Their recycled yarn initiative includes recycling waste yarn from the production process, while it also takes waste cotton yarn and blends it with REPREVE® fibres to create an eco-friendly denim fabric. Kipas also uses BCI cotton and organic cotton, and targets each to be 15% and 5% of total consumption, respectively. Furthermore, their Conservablue technology aims to reduce the environmental impact of the dyeing process by eliminating the use of rinsing overflow boxes before and after the indigo dye boxes, as well as ensuring 100% of applied dyestuff remains on the yarn in the rinsing bath.

As well as the overseas offerings, a wide range of domestic denim exhibitors covering all price and quality points will also feature in Beyond Denim. Some of the more notable brands participating include Advance Denim, Black Peony, Guangzhou Foison and Prosperity Textile.

Denim’s ‘next move’ to be debated in INVISTA panel discussion
The market is changing and so must apparel and textile manufacturers. Low prices and discounts are no longer driving sales the way they used to. Today’s consumer wants better quality, appreciates new technology and is evolving their casualwear style. This is the premise behind the INVISTA-sponsored panel discussion which will take place on day 1 of the fair. Titled ‘Denim’s Next Move – New Opportunities to Keep Growing Sales of Jeans and Casualwear at Retail’, participants will learn what consumers really want in jeans and casualwear, the return of chinos and new fabric technologies that are energising casualwear.

The panel will be moderated by Jane Singer, Director and Head of Market Development at Inside Fashion. Panellists will include representatives from Advance Denim, Guangzhou Conshing Clothing Group, Prosperity Textile and Texhong who will share their latest innovations that will help brands and retailers drive sales and profits.

In addition to Intertextile Shanghai Apparel Fabrics, four other textile fairs also take place at the National Exhibition and Convention Center: Yarn Expo Spring, Intertextile Shanghai Home Textiles – Spring Edition, fashion garment fair CHIC and knitting fair PH Value.
