Emerging Trends in Sustainable and Technical Textiles

Sustainability within the fashion industry is no longer a new concern for brands to consider for implementation, but rather an integrated factor that is part of an industry standard.The latest innovations are no longer surface level, but are developing into sophisticated and scalable systems in order to combat the astronomical waste the textile industry is responsible for.

A closer look at trends in sustainable & technical textiles…

Advanced Circularity

What used to be a niche concept and optional consideration for companies to implement, circular practices have grown into more of an industry standard, being pushed by recycled and bio-based textiles. Large projects such as ALADIN aim to advance circular textile production in Europe, through integrating digital platforms and local demand-driven systems to reduce overproduction.

Biodegradable Fabrics

The development and technology surrounding biodegradable materials have offered a lifeline for the textile industry, especially in regard to packaging. Currently, the industry is exploring a shift towards biodegradable clothing, with more research being funded to develop specific fibres that can mirror the same strength and flexibility of natural materials.

For example, the Bezos Earth Fund has awarded $10 million to research in developing biodegradable fibres with a “waste to weave” process, taking inspiration from protein-based silk woven by spiders.

Smart Textiles

The smart textiles market is projected to surge toward $8.48 billion by 2034, with a CAGR of 14.9% during the forecast period. In essence, smart textiles are fabrics that integrate electronic components, sensors and other advanced materials. This rapid evolution signifies the transformation from smart textiles into “ultra-smart” capabilities, including cognitive processing, dual-stimuli response and autonomous adaptation, which can be leveraged to reduce waste and optimise energy use.

Recycling Catalysts

Recycling catalysts are fundamental agents in textile recycling, with reactions such as photocatalytic oxidation being used to break down organic pollutants. Other catalysts include:

Anaerobic Digestion

Transforms textile waste into renewable biogas by using specialised microorganisms, acting as a biological upcycling pathway.

Fermentation

Uses microorganisms like bacteria to break down natural or blended fibres and converts it into chemical building blocks, commonly targeting complex materials like cotton-polyester blends.

Composting

Transforms organic materials into nutrient-dense soil, which can be applied to 100% natural textile fibres like cotton, linen, hemp and wool.

Fibre Regeneration

This process breaks down textiles and recovers them at molecular levels, enabling these fibres to be re-spun into new yarns and fabrics, resulting in an infinite-cycle material recovery.

Thermal Recovery

As a recycling catalyst, thermal recovery is a heat-based process used to break down mixed or synthetic clothing waste, often non-recyclable, where energy is recovered into textile recycling.

Plant-Based Leather

As the textile industry has been discovering alternatives to fur, leather and skins, a variety of plant-based solutions have emerged over the years, sourced from the likes of fruit waste to grain proteins.

Piñatex

Utilises the pineapple leaf often discarded within the fruit industry. Coated with a water-based PU resin, Piñatex is partly biodegradable in controlled conditions. 

Mycelium

Grown from root-like thread structures of fungi to mimic animal hide from forestry by-products such as sawdust, and is currently being scaled for wider industry use.

AppleSkin

Leftover waste residue and fibres from industry, including skins, seeds and cores are dried and crushed into a fine powder and mixed with a PU binder.

Desserto

Made from cactus components sourced in Mexico, often supported with bio-resin or recycled backing fabrics.

Uncaged

Derived from grain proteins and possesses similar structure to collagen in skins, as well as the ability to be embossed and used similarly to any animal-derived leather.
