The nominees:

The Straw Flexi-Dress: Design Meets Sustainability – DITF & VRETENA (DE)
The Flexi-Dress design was inspired by the natural golden colour and silky touch of HighPerCell® (HPC) filaments based on unbleached straw pulp. These cellulose filaments are produced using environmentally friendly spinning technology in a closed-loop production process. The design decisions focused on the emotional connection and attachment to the HPC material to create a local and circular fashion product. The Flexi-Dress is designed as a versatile knitted garment – from work to street – that can be worn as a dress, but can also be split into two pieces – used separately as a top and a straight skirt. The top can also be worn with the V-neck front or back. The HPC textile knit structure was considered important for comfort and emotional properties.

Additionally, it is verified in the Product Environmental Footprint.

LENZING™ Cellulosic Fibres for Glacier Protection – Lenzing (AT)
Glaciers are now facing an unprecedented threat from global warming. Synthetic fibre-based geotextiles, while effective in slowing down glacier melt, create a new environmental challenge: microplastics contaminating glacial environments. The use of such materials contradicts the very purpose of glacier protection, as it exacerbates an already critical environmental problem. Recognizing this problem, the innovative use of cellulosic LENZING™ fibres presents a pioneering solution. The Institute of Ecology, at the University of Innsbruck, together with Lenzing and other partners made first trials in 2022 by covering small test fields with LENZING™ fibre-based geotextiles. The results were promising, confirming the effectiveness of this approach in slowing glacier melt without leaving behind microplastic.

The RENU Jacket – Advanced Recycling for Cellulosic Textiles – Pangaia (UK) & Evrnu (US)
PANGAIA LAB was born out of a dream to reduce barriers between people and the breakthrough innovations in material science. In 2023, PANGAIA LAB launched the RENU Jacket, a limited edition product made from 100% Nucycl® – a technology that recycles cellulosic textiles by breaking them down to their molecular building blocks, and reforming them into new fibres. This process produces a result that is 100% recycled and 100% recyclable when returned to the correct waste stream – maintaining the strength of the fibre so it doesn’t need to be blended with virgin material.
Through collaboration with Evrnu, the PANGAIA team created the world’s first 100% chemically recycled denim jacket, replacing a material traditionally made from 100% virgin cotton. By incorporating Nucycl® into this iconic fabric construction, dyed with natural indigo, the teams have demonstrated that it’s possible to replace ubiquitous materials with this innovation.

Textiles Made from Easy-to-dye Biocelsol – VTT Technical Research Centre of Finland (FI)
One third of the textile industry’s wastewater is generated in dyeing and one fifth in finishing. But the use of chemically modified Biocelsol fibres reduces waste water. The knitted fabric is made from viscose and Biocelsol fibres and is only dyed after knitting. This gives the Biocelsol fibres a darker shade, using the same amount of dye and no salt in dyeing process. In addition, an interesting visual effect can be achieved. Moreover, less dye is needed for the darker colour tone in the finished textile and the possibility to use the salt-free dyeing is more environmentally friendly.
These special properties of man-made cellulosic fibres will reassert the fibres as a replacement for the existing fossil-based fibres, thus filling the demand for more environmentally friendly dyeing-solutions in the textile industry. The functionalised Biocelsol fibres were made in Finnish Academy FinnCERES project and are produced by wet spinning technique from the cellulose dope containing low amounts of 3-allyloxy-2-hydroxypropyl substituents. The functionality formed is permanent and has been shown to significantly improve the dyeability of the fibres. In addition, the functionalisation of Biocelsol fibres reduces the cost of textile finishing and dyeing as well as the effluent load.

A New Generation of Bio-based and Resource-efficient Fibre – TreeToTextile (SE)
TreeToTextile has developed a unique, sustainable and resource efficient fibre that doesn't exist on the market today. It has a natural dry feel similar to cotton and a semi-dull sheen and high drape like viscose. It is based on cellulose and has the potential to complement or replace cotton, viscose and polyester as a single fibre or in blends, depending on the application.
TreeToTextile Technology™ has a low demand for chemicals, energy and water. According to a third party verified LCA, the TreeToTextile fibre has a climate impact of 0.6 kg CO2 eq/kilo fibre. The fibre is made from bio-based and traceable resources and is biodegradable.

• Growing geographic separation between cotton production and textile manufacturing since the 1990s

The United States Department of Agriculture (USDA) released a comprehensive study about Chinese cotton in August 2022. The authors, Fred Gale and Eric Davis, concentrate on textiles, imports and Xinjiang.

China is the world’s largest textile manufacturer and the largest cotton consumer, but changes in China’s economy are reshaping the geography of its cotton-textile sector. Nearly all of China’s cotton is produced in the Xinjiang Uyghur Autonomous Region (XUAR), also known more simply as Xinjiang.

Their study reviewed the regional patterns of China’s cotton textile industry development and identified growing geographic separation between cotton production and textile manufacturing since the 1990s using data from Chinese sources. The study investigated spatial patterns of demand for imported cotton by analyzing lists of Chinese companies applying for a share of the import quota from 2016 to 2022. Multiple regression analysis was used to control for potentially confounding influences when investigating whether companies in coastal provinces were more likely to use imported cotton than similarly sized companies in other regions.

Textile manufacturers — the main consumers of cotton — are concentrated in coastal and central regions where the share of China’s cotton production fell from over 50 percent to 10 percent during 2011–21. These geographic changes are a factor influencing global trade in cotton and textiles. Additionally, the use of forced labor in Xinjiang attracted more attention to the industry, prompting the United States and other countries to ban products produced in the region.

This study reviews the economic, geographic, and policy factors reshaping the industry and influencing the global trade of cotton and textile products. The study also examines data on Chinese companies applying for a share of China’s cotton import quota to gain insight about the demand for imported cotton.

China became the world’s largest producer, consumer, and importer of cotton soon after joining the World Trade Organization (WTO) in 2001. Despite adopting a tariff-rate quota (TRQ) system for cotton imports and issuing supplemental quotas in most years, the large number of cotton goods manufacturers that request shares of the quota suggests demand for imported cotton exceeds  the quota.

While the TRQ was intended to protect China’s cotton farmers, many farmers abandoned the labor-intensive crop as wages rose rapidly in many other industries and other crops produced higher returns. In response, officials encouraged cotton production in the relatively remote region of Xinjiang to prevent China from becoming reliant on imported cotton. Xinjiang growers receive a subsidy payment for cotton, and subsidies for machinery and seeds. A transportation subsidy induces textile manufacturers in eastern and central regions to purchase cotton from Xinjiang, which is about 2,200 to 2,900 miles from most of the country’s textile manufacturers. Financial support and other incentives encourage manufacturers to shift operations to Xinjiang.

Textile manufacturers in China are highly interested in importing cotton due to its lower price and quality. China imports about 20 percent of its cotton, and the United States is a chief exporter of cotton to China. While imported cotton is used in all provinces, manufacturers near the eastern seaboard show a greater propensity for imports. Nevertheless, in all regions, domestic cotton has the largest share of mill use.

Between 2016 and 2022, 1,581 companies applied for a share of the TRQ, and 265 companies applied in all 7 years. Most of these companies also applied for supplemental quotas issued with slightly higher tariffs. This large number of applicants suggests that imports could be even greater if quotas did not limit them. The operation of the quota application process is not public information, but data submitted by applicants suggests access to imported cotton is uneven. About 14 percent of applicants said imported cotton comprised over half of the cotton they used. Another 20 percent of companies requesting import quota did not use any imported cotton, suggesting that many applicants are unable to import. Textile manufacturers coped with limits on cotton imports by increasing their use of synthetic, chemical-based fibers or by importing cotton yarn. From 2000 to 2020, China’s yarn imports doubled from under 1 million metric tons to around 2 million metric tons with Vietnam supplying about 45 percent of that total in 2020.

The number of textile manufacturers in Xinjiang applying for a share of the cotton import quota rose from 37 to 68 between 2016 and 2022. However, imports constituted less than 2 percent of  the cotton Xinjiang applicants reported using—and 66 percent of them reported using no imported cotton—suggesting that applications from Xinjiang textile companies were often denied.
Analysis found that applicants in coastal provinces used more imported cotton than similarly sized applicants in other regions. Each location of a multi-plant company must apply separately for tariff-rate quotas. Textile manufacturers in Xinjiang that requested a share of the import quota included branches of some of China’s largest textile companies, but the analysis found that Xinjiang applicants used less imported cotton than similar manufacturing plants located in other regions. China’s role as a cotton importer appears to have peaked, while other countries are increasing their share of imports.

USDA baseline projections suggest that by 2030 Vietnam, Pakistan, Indonesia, Bangladesh, and Turkey will together account for 47 percent of the world’s cotton imports while China will only account for 24 percent. The study cam be downloaded from the USDA website.
