From the Sector

Electronically conductive fibres are already in use in smart textiles, but in a recently published research article, ionically conductive fibres have proven to be of increasing interest. The so-called ionofibres achieve higher flexibility and durability and match the type of conduction our body uses. In the future, they may be used for such items as textile batteries, textile displays, and textile muscles.

The research project is being carried out by doctoral student Claude Huniade at the University of Borås and is a track within a larger project, Weafing, the goal of which is to develop novel, unprecedented garments for haptic stimulation comprising flexible and wearable textile actuators and sensors.

In Claude Huniade’s project, the goal is to produce conductive yarns without conductive metals.
"My research is about producing electrically conductive textile fibres, and ultimately yarns, by coating non-metals sustainably on commercial yarns. The biggest challenge is in the balance between keeping the textile properties and adding the conductive feature," said Claude Huniade.

Currenty, the uniqueness of his research leans towards the strategies employed when coating. These strategies expand to the processes and the materials used.

Uses ionic liquid
One of the tracks he investigates is about a new kind of material as textile coating, ionic liquids in combination with commercial textile fibres. Just like salt water, they conduct electricity but without water. Ionic liquid is a more stable electrolyte than salt water as nothing evaporates.

"The processable aspect is an important requirement since textile manufacturing can be harsh on textile fibres, especially when upscaling their use. The fibres can also be manufactured into woven or knitted without damaging them mechanically while retaining their conductivity. Surprisingly, they were even smoother to process into fabrics than the commercial yarns they are made from," explained Claude Huniade.

Ionofibres could be used as sensors since ionic liquids are sensitive to their environment. For example, humidity change can be sensed by the ionofibers, but also any stretch or pressure they are subjected to.

"Ionofibres could truly shine when they are combined with other materials or devices that require electrolytes. Ionofibres enable certain phenomena currently limited to happen in liquids to be feasible in air in a lightweight fashion. The applications are multiple and unique, for example for textile batteries, textile displays or textile muscles," said Claude Huniade.

Needs further research
Yet more research is needed to combine the ionofibres with other functional fibres and to produce the unique textile devices.

How do they stand out compared to common electronically conductive fibres?
"In comparison to electronically conductive fibres, ionofibers are different in how they conduct electricity. They are less conductive, but they bring other properties that electronically conductive fibers often lack. Ionofibres achieve higher flexibility and durability and match the type of conduction that our body uses. They actually match better than electronically conductive fibres with how electricity is present in nature," he concluded.

• Aims to tackle the immense textile waste generated in urban environments, on the back of import bans of waste materials
• Addresses the shortcomings of current textile recycling technologies, which are unsuitable for urban settings due to the use of heavy chemicals
• Technologies developed by the newly-formed RGE-NTU Sustainable Textile Research Centre will be test-bedded in RGE’s pilot urban-fit textile recycling plant, projected for completion as early as 2024

Royal Golden Eagle (“RGE”), a global group of resource-based manufacturing companies, which includes a world-leading viscose fibre producers Sateri and Asia Pacific Rayon (APR), is developing urban-fit, closed-loop textile-to-textile recycling solutions, through the newly-formed RGE-NTU Sustainable Textile Research Centre (RGE-NTU SusTex). This is a five-year research collaboration between RGE and Nanyang Technological University, Singapore (“NTU”), to accelerate innovation in textile recycling that can be deployed in urban settings. The research centre will develop new technologies to recycle textile waste into fibre and create new, next-generation eco-friendly and sustainable textiles.

This move comes on the back of the tightening of waste import bans in countries such as China, India and Indonesia, which are among the world’s largest waste processors. The stricter import bans have left cities in need of viable local textile recycling solutions to tackle the immense textile waste generated.

RGE Executive Director, Mr Perry Lim, said, “Current textile recycling technologies, which rely primarily on a bleaching and separation process using heavy chemicals, cannot be implemented due to environmental laws. At the same time, there is an urgent need to keep textiles out of the brimming landfills.” He added, “As the world’s largest viscose producer, we aim to catalyse closed-loop, textile-to-textile recycling by developing optimal urban-fit solutions that can bring the world closer to a circular textile economy.”

Globally, an estimated 90 million tonnes of textile waste is generated and disposed of every year, with less than 1% being upcycled into new clothing or other textile materials. By 2030, the amount of global textile waste, which currently accounts for almost 10% of municipal solid waste, is expected to reach more than 134 million tonnes. The textile industry is also responsible for 10% of global greenhouse gas emissions – more than international flights and maritime shipping combined.

At present, most of the available textile recycling technologies are open-loop, where textile waste is typically downcycled to lower-quality products (insulating materials, cleaning cloths, etc.) or be used in waste-to-heat recycling.

“Closed-loop textile-to-textile recycling processes, particularly chemical recycling, are still under development. Scaling up the technologies to industrial scale remains a challenge. A key bottleneck is that refabricating textile waste into fibre needs purity standards for feedstock. However, most of the clothes that we wear are made of a mixture of different synthetic and natural fibres, which makes separating the complex blends of materials challenging for effective recycling.

“Our aim is to address this industry pain point by developing viable solutions that use less energy, fewer chemicals and produces harmless and less effluents, and then potentially scale up across our global operations,” Mr Lim said.

To tackle the key challenges in closed-loop textile recycling, RGE-NTU SusTex is looking into four key research areas, namely cleaner and more energy efficient methods of recycling into new raw materials, automated sorting of textile waste, eco-friendly dye removal, and development of a new class of sustainable textiles that is durable for wear and, at the same time, lends itself to easier recycling.

Technologies developed by RGE-NTU SusTex will be test bedded at RGE’s pilot urban-fit textile recycling plant in Singapore, which is projected for completion as early as 2024. If successful, RGE has plans to replicate the plant in other urban cities within its footprint.

Cotton Incorporated published its monthly economic letter of August and shared new insights of the cotton prices:

Cotton prices continue to be caught between the two competing storylines that have been in play for the past several months.
On one side, there is the deteriorating global macroeconomic situation.  The International Monetary Fund (IMF) lowered its projection for global economic growth in both 2022 (3.2%) and 2023 (2.9%) in the updates released in late July.  Current IMF forecasts are significantly beneath those from January (called for 4.4% growth in 2022 and 3.8% growth in 2023) and April (called for 3.6% growth in 2022 and 3.6% growth in 2023).  The evolution in the macroeconomy was a likely factor contributing to the shift in investors’ outlook on the commodity sector, which led to a collapse in prices for cotton and a range of other commodities in June and July.

Beyond the weakening macroeconomic environment, there also may be factors associated with cotton supply chains that could affect demand during the 2022/23 crop year.  Downstream consumer markets for cotton can be viewed as more discretionary than other spending categories, such as food, energy, and lodging, that experienced some of the sharpest effects of inflation.  Given price increases for necessities, consumers may have less income to devote to apparel and home furnishings.

In the U.S., consumer spending on clothing has been flat for the past year.  However, it has been holding at levels that are 25% higher than they were in 2019.  If U.S. consumers pull back on clothing purchases, it may hit the market just as retailers have caught up with consumer demand after the onset of the shipping crisis.  In weight volume, the cotton contained in U.S. apparel imports was up 22% year-over-year in the first half of 2022.  Relative to 2019 (pre-COVID and pre-shipping crisis), the volume in the first half of 2022 was up 23%.  Given strong import volumes, if there is a dip in consumer demand, inventory could build both at retail and upstream in supply chains.  This could lead to cancelations, potentially all the way back to the fiber level, where contracts signed at prices higher than current values could be particularly susceptible.

Tight U.S. supply is on the other side of price direction arguments.  Cotton is drought tolerant, and that is why it can be viably grown in perennially dry locations like West Texas.  However, cotton requires some moisture to germinate and generate healthy yields.  West Texas has had very little rain over the past year, and drought conditions have been extreme.  As a result, abandonment is forecast to be widespread.  It remains to be seen exactly how small the U.S. crop will be, but the current USDA forecast predicts only 12.6 million bales in 2022/23 (-5.0 million fewer bales than in 2021/22).

Meanwhile, demand for U.S. cotton has been relatively consistent, near 18 million bales over the past five crop years (an average of 15.5 million bales of exports and 2.7 million bales of domestic mill-use).  A harvest of only 12.6 million falls well short of the recent average for exports alone, and U.S. stocks were near multi-decade lows coming into 2022/23.  All these statistics suggest shipments from the world’s largest exporter may have to be rationed in 2022/23.  If cotton is not readily available from other sources, the scarcity of supply from the U.S. could support prices globally.

Simultaneously, there is weakness from the demand side.  The market has struggled to find the balance between the weakened demand environment and limited exportable supply in recent months.  The conflict between these two influences makes it difficult to discern a clear direction for prices and suggests continued volatility.

SUPPLY, DEMAND, & TRADE
The latest USDA report featured reductions to figures for both world production and mill-use for both the 2021/22 and 2022/23 crop years.  For 2021/22, the global production estimate was lowered -0.7 million bales (to 116.2 million) and global consumption was lowered -1.9 million bales (to 119.8 million).  For 2022/23, the global production forecast was lowered -1.2 million bales (to 120.7 million) and global consumption was lowered -1.6 million bales (to 119.9 million).

With the decreases in use exceeding the declines in production, figures for global ending stocks increased.  For 2021/22, the projection rose +1.1 million bales (to 84.0 million).  For 2022/23, the forecast increased +1.6 million bales (to 84.3 million).

At the country-level, the largest changes to 2021/22 production were for Brazil (-400,000 bales to 12.3 million) and Uzbekistan (-100,00 bales to 2.7 million).  The largest changes for the 2022/23 harvest were for the U.S. (-1.0 million bales to 15.5 million) and Brazil (-200,000 bales to 13.0 million).

It may be notable that there were no upward country-level revisions for mill-use in either 2021/22 or 2022/23.  The largest revisions for 2021/22 included those for China (-1.0 million to 37.0 million), Vietnam (-400,000 bales to 6.9 million), Bangladesh (-300,000 to 8.0 million), Pakistan (-100,000 bales to 10.9 million), and Uzbekistan (-100,000 bales to 2.7 million).  For 2022/23, consumption estimates were lowered for China (-500,000 bales to 37.5 million), India (-500,000 bales to 25.0 million), Bangladesh (-300,000 bales to 8.6 million), and Vietnam (-300,000 bales to 7.1 million).
The global trade forecast for 2022/23 was lowered -1.1 million bales (to 46.4 million).  The most significant changes on the import side included those for China (-500,000 bales to 10.0 million), Bangladesh (-300,000 bales to 8.5 million), and Vietnam (-300,000 bales to 7.2 million).  On the export side, the largest updates included those for the U.S. (-500,000 bales to 14.0 million) and Australia (+300,000 bales to 6.0 million).
 
PRICE OUTLOOK
Recent volatility was not limited to the cotton market.  A wide range of commodities lost significant value in June.  Between June 9th and July 5th (dates chosen unsystematically to describe the magnitude of declines), cotton fell -25% (NY/ICE December futures), corn fell -19% (Chicago Board of Trade, December contract), soybeans fell -17% (Chicago Board of Trade, November contract), wheat fell -25% (Chicago Board of Trade, December contract), copper fell -20% (London Metal Exchange, nearby), and Brent crude oil fell -12% (ICE, nearby).

The breadth of losses throughout the commodity sector suggests a sea change in investor sentiment for the entire category.  The effects of inflation, the withdrawal of stimulus, rising interest rates, and concerns about a possible recession could all be reasons explaining a reversal of speculative bets, and all could be contributors to the losses.  While the macroeconomic environment can be expected to continue to weigh on prices, there are also supportive forces for the market that are specific to cotton.

The current USDA forecast for U.S. cotton production is 15.5 million bales, and it may get smaller over time because of the severe drought in West Texas.  The current harvest figure is two million bales lower than the 2021/22 number and is equal to the five-year average for U.S. cotton exports (2017/18-2021/22).  On top of exports, the U.S. will need to supply domestic mills with 2.5 million bales.  The last time the U.S. had a severely drought-impacted crop (2020/21), the harvest was only 14.6 million bales.  In that crop year, the U.S. was able to export more than it grew because it had accumulated stocks in the previous year.  The U.S. is coming into the 2022/23 crop year with low stocks.  This suggests U.S. shipments may have been rationed.  Since the U.S. is the world’s largest exporter, this may lend some support to prices internationally.

Carbios has signed an agreement with On, Patagonia, PUMA, and Salomon, to develop solutions that will enhance the recyclability and circularity of their products.
 
An important element of the two-year deal will be to speed up the introduction of Carbios’ biorecycling technology, which constitutes a breakthrough for the textile industry. Carbios and the four companies will also research how products can be recycled, develop solutions to take-back worn polyester items, including sorting and dismantling technologies, and gather data on fiber-to-fiber recycling as well as circularity models.
 
The challenge the four brands share, is that their ambitious sustainable development goals can only partially be met by conventional recycling technologies which mostly target bottle-to-fiber recycling. Future regulations will require more circularity in packaging and textile. Yet the market consensus is that there will soon be a shortage of PET bottles, as they will be used for circular production methods in the Food & Beverage Industry.   
 
Carbios’ innovative process constitutes a technological breakthrough for the recycling of polyester (PET) fibers, which are widely used in apparel, footwear and sportswear, on their own or together with other fibers. PET polyester is the most important fiber for the textile industry with 52 MT produced, even surpassing cotton at 23MT. The biorecycling process uses an enzyme capable of selectively extracting the polyester, recovering it to recreate a virgin fiber. This revolutionary technology makes it possible to recover the PET polyester present in all textile waste that cannot be recycled using traditional technologies.
 
PET plastics and fibers are used to make everyday consumer goods such as bottles, packaging and textiles. Today, most PET is produced from fossil resources, then used and discarded according to a wasteful linear model. By creating a circular economy from used plastics and fibers, Carbios’ biorecycling technology offers a sustainable and more responsible solution.

Natural fibers are among the most important raw materials in the textile and fashion industry worldwide. For centuries, they have fed millions of people through their cultivation or breeding, and it is impossible to imagine daily life without them. Especially at the moment, natural fibers are gaining special importance due to the intense discussions about sustainable living. Even though natural fibers have accompanied mankind for a long time, they are changeable, technical, and adaptable to the challenges of the textile industry.

The Discover Natural Fibres Initiative (DNFI) is celebrating natural fibres in a program to be conducted during Heimtextil in Frankfurt on 23 June. Anyone with an interest in the role of natural fibres in the world economy, economic indicators of textile activity, innovations in natural fibre research, and updates on proposed EU legislation affecting textiles is welcome to attend.

The program will include various presentations by the previous and current award winners, presentations, and discussions:
