Recycled Fashion: Materials, Methods and Quality – A Technical Overview

In response to increasing environmental scrutiny, the global fashion industry is undergoing a structural shift toward more sustainable practices. Among these, recycled fashion has emerged as a leading innovation—offering the potential to mitigate textile waste, reduce virgin material use, and lower carbon emissions across supply chains.

But for many consumers and industry stakeholders, questions remain. What are recycled garments made from? What technologies are involved? And critically—are recycled materials durable, high-performing, and commercially viable at scale?

This technical overview breaks down the material science behind recycled fashion, assesses quality implications, and examines how platforms like Tellar.co.uk are helping consumers make smarter, more sustainable sizing choices—ensuring garments are purchased accurately and worn longer.

1. Definition and Scope of Recycled Fashion

Recycled fashion refers to clothing and accessories manufactured from materials that have been reclaimed and processed from pre-consumer or post-consumer waste streams.

• Pre-consumer waste includes offcuts, fabric remnants, and defective stock from factories.

• Post-consumer waste includes used garments, plastic packaging, discarded fishing nets, and industrial materials.

There are two primary technological pathways:

• Mechanical Recycling: Involves physical breakdown—such as shredding, melting, or carding—to reconstitute fibres.

• Chemical Recycling: Utilises solvents or enzymatic processes to reduce textiles to base monomers or polymers, allowing regeneration into virgin-equivalent fibres.

Each method carries distinct implications for fibre integrity, lifecycle emissions, and cost-efficiency.

2. Core Recycled Materials Used in Fashion

2.1 Recycled Polyester (rPET)

Derived primarily from post-consumer PET plastics, including water bottles and packaging, rPET is the most widely used recycled textile globally.

• Use Cases: Sportswear, outerwear, linings, accessories

• Properties: Lightweight, moisture-wicking, colourfast

• Lifecycle Impact: Requires 59% less energy to produce than virgin polyester (Source: WRAP UK)

• Limitations: Non-biodegradable; may shed microplastics during washing

Recycled polyester is often indistinguishable in performance from virgin polyester when processed through advanced filtration and extrusion methods.

2.2 Recycled Cotton

Recycled cotton is produced by mechanically shredding textile waste into fibres. While environmentally favourable, the mechanical process shortens fibres, reducing softness and strength.

• Use Cases: Denim, t-shirts, loungewear, insulation

• Properties: Breathable, low-impact, biodegradable

• Lifecycle Impact: Saves ~20,000 litres of water per tonne compared to virgin cotton (Source: Textile Exchange)

• Limitations: Degraded fibre length often necessitates blending with virgin cotton or synthetic reinforcement

The fibre quality and final fabric durability are directly tied to the quality and uniformity of the input material.

2.3 Recycled Wool

Sorted by colour and quality, wool garments are shredded and re-spun into new yarns. Recycled wool retains many of the thermal and structural properties of virgin wool due to its long-staple fibres.

• Use Cases: Knitwear, outerwear, accessories

• Properties: Insulating, resilient, biodegradable

• Lifecycle Impact: Substantially reduced water and dye usage

• Limitations: May pill or lose softness if processed at lower grade

High-grade recycled wool, often blended with virgin fibres, is now seen in premium capsule collections across British brands such as Toast and Community Clothing.

2.4 Recycled Nylon (ECONYL®)

ECONYL® is a chemically regenerated nylon made from waste such as discarded fishing nets, carpets, and pre-consumer scraps.

• Use Cases: Swimwear, lingerie, performancewear

• Properties: Strong, elastic, quick-drying

• Lifecycle Impact: Saves 70,000 barrels of crude oil per 10,000 tonnes produced (Source: Aquafil)

• Limitations: More energy-intensive than mechanical methods; requires specific infrastructure

Despite its cost, ECONYL® is favoured in high-end and technical fashion for its purity and repeat recyclability.

2.5 Upcycled Garments and Reclaimed Textiles

Distinct from fibre-level recycling, upcycling uses whole garments or offcuts, which are reconstructed into new apparel without being broken down.

• Use Cases: Artisanal fashion, small-batch collections, bespoke tailoring

• Properties: Highly individual, low-waste

• Lifecycle Impact: Highest material efficiency; minimal energy input

• Limitations: Labour-intensive; hard to scale commercially

British designers such as Bethany Williams and Priya Ahluwalia have built award-winning brands around the upcycling philosophy.

3. Assessing Quality: How Do Recycled Materials Perform?

The assumption that recycled materials are inherently inferior is outdated. In many cases, recycled fabrics meet or exceed the performance standards of virgin fibres—when sourced and processed responsibly.

Critical success factors include blend ratios, fabric construction, post-processing treatments, and manufacturer quality control.

4. Consumer Misconceptions and Greenwashing Risk

While recycled fashion presents clear benefits, there are limitations that consumers should be aware of:

• Many products labelled “recycled” only contain minimal recycled content (e.g. 5–10%)

• Vague claims such as “eco” or “sustainable” are often not third-party verified

• Blended fabrics (e.g. cotton-poly) may be technically unrecyclable in their final form

To ensure transparency, consumers should look for standards such as:

• Global Recycled Standard (GRS)

• Recycled Claim Standard (RCS)

• OEKO-TEX® and Bluesign® certifications

Clarity around fibre composition is also essential when shopping for a durable, high-quality product.

5. Fit and Longevity: The Tellar.co.uk Advantage

Even the most sustainable garment is a poor investment if it doesn’t fit—or ends up returned and unworn.

Tellar.co.uk is the UK’s leading size-matching platform, using actual body measurements to recommend the correct size in over 1,500 clothing brands—including those using recycled materials.

Key Tools:

• ✅ Free printable measuring tape

• ✅ User profile creation to store measurements

• ✅ Real-time store size lookup

• ✅ Recommendations in UK, US, EU sizing, by inches or cm

This ensures consumers buy once, buy right, and reduce the environmental impact of returns—a major sustainability concern.

6. Conclusions: Recycled Fashion and Future Outlook

Recycled fashion is not a trend—it’s a necessary adaptation within a resource-constrained world. Material technology continues to improve, with chemical recycling and fibre regeneration making progress toward scalability.

However, its success hinges on more than materials. It requires:

• Consumer education on what “recycled” really means

• Brand transparency about fibre sources and construction

• Sizing accuracy, to ensure garments are used, not wasted
