01 — The white short

Everything you'd expect from a legging short.
One ingredient missing.

No conventional elastane in the intended textile construction. That is the starting point of our M˚Pulse legging shorts.

The development goal is to bring useful stretch, recovery, fit and compression-inspired support into garments without depending on conventional elastane. A new approach to athletic wear is taking shape.

03 / Why challenge elastane?

Ten reasons to
ask a better question.

01

One more material

Elastane can add another polymer category to a garment, complicating some separation and recycling routes.

RESEARCH CONTEXT ↗
02

The sorting challenge

Small elastane fractions can be difficult to characterize with some automated textile sorting processes.

RESEARCH CONTEXT ↗
03

Less predictable feedstock

Recycling systems work best with known, consistent input streams; complex mixtures can lower recovery efficiency.

RESEARCH CONTEXT ↗
04

Mechanical recycling limits

Some stretch constructions complicate opening, shredding and reclaiming fiber fractions efficiently.

RESEARCH CONTEXT ↗
05

Purity requirements

Certain fiber-to-fiber processes require controlled material purity for reliable output quality.

RESEARCH CONTEXT ↗
06

An extra separation step

Even small proportions of another polymer can create treatment or purification needs for certain recycling technologies.

RESEARCH CONTEXT ↗
07

Heat changes the equation

Different polymer behaviors under temperature can create challenges in specific thermal recycling routes.

RESEARCH CONTEXT ↗
08

Processing compatibility

Some elastomer-containing fractions may require special handling or filtering in selected processing systems.

RESEARCH CONTEXT ↗
09

The economics of recovery

More sorting and purification can affect the cost and value of recovered textile materials.

A new design brief

Circular design asks an important question: when can we deliver the function without adding an additional material?
