Fibres with inherent elasticity from natural or regenerated sources

about
Natural Stretch

Natural stretch fibres combine inherent elasticity in natural or regenerated fibres to offer comfort and fit benefits without synthetics

Natural stretch relies on fibre properties, mechanical innovation, or fabric construction techniques (such as rib knitting or weaving) to provide elasticity without the use of synthetic fibres. Materials like Coreva™, a stretch denim incorporating natural rubber, demonstrate how innovation can deliver performance.

Partially bio-based fibres, such as Sorona, present improved options compared to petroleum-based elastane but are not fully circular. The most responsible solutions come from 100% natural, biodegradable blends that offer stretch without leaving a lasting environmental impact.

our ranking

Natural stretch fibres are preferred

A

Preferred

Preferred materials are considered to be the least environmentally impactful, sustainable, and ethical options for textile production. These materials are often made from natural, renewable resources, and are processed using methods that have minimal impact on the environment. These materials are typically more expensive than synthetic alternatives, but are considered to be worth the extra cost due to their positive environmental and ethical impact, as well as longevity and resell value at end of life.

How to Source Better

Natural Stretch

Substitutes for

Natural Stretch

We recommend using certified biodegradable natural stretch options like Coreva™, which combines organic cotton with a natural rubber core to deliver plastic-free, compostable stretch denim. Pairing organic fibres such as cotton, hemp, or bamboo with mechanical methods like rib knitting or weaving can also provide effective elasticity without relying on elastane.
