For AW26, stretch fabric is no longer a comfort sidekick defined by 'a bit of spandex.' It has become the performance core pursued by sportswear, intimates, outerwear and even tailoring. From Milan to Shanghai, bio-based spandex blends, three-dimensional stretch jacquards and extreme 4-way stretch are redrawing the boundaries of elasticity. The season's keywords: adaptive, recoverable, low environmental load.

Trend Watch

Spandex blends are undergoing a quiet revolution. Conventional petroleum-based spandex offers excellent stretch but is non-recyclable and energy-intensive. For AW26, bio-based spandex (from corn or castor beans) and recycled spandex (rECONYL® etc.) are blended at significantly higher ratios. When interwoven with recycled polyester, organic cotton or lyocell, elastic recovery can exceed 95% while cutting carbon footprint by 30%. Brands no longer ask only 'how much stretch?' but 'does it recover, and can it degrade?'

Stretch jacquards are moving from decoration to function. In the past, jacquards relied on spandex core-spun yarns for elasticity. Now, double-layer structures and high-shrinkage yarns create 'structural stretch'—20%-30% elongation without spandex. This is especially popular in sports outerwear and shaping intimates because breathable and support zones can be woven in one piece, reducing seams and enhancing comfort.

4-way stretch continues to deepen in sportswear and intimates. In sports, it combines with laser cutting and ultrasonic welding for seamless activewear. In intimates, paired with micro-denier nylon, it delivers a 'second-skin' fit with antibacterial and cooling functions. For AW26, 4-way stretch also begins to integrate phase-change material microcapsules for dynamic moisture and temperature management.

Industry Impact

The upgrade in stretch fabrics is reshaping supply chains. Upstream spandex makers are accelerating bio-based and recycled routes. Midstream weavers are investing in high-gauge circular knitting and jacquard warp knitting machines. Downstream brands demand full traceability. For mills, stretch jacquards are technically demanding, requiring precise tension control and inline inspection to avoid barré and uneven elasticity.

Cost structures are shifting. Bio-based spandex remains 20%-40% more expensive than conventional, but brands are willing to pay a premium for 'traceable stretch.' In export markets, the EU's Carbon Border Adjustment Mechanism and Digital Product Passport impose stricter requirements on carbon footprint and chemical composition. Exporters need to prepare LCA data and certifications such as bluesign® and OEKO-TEX®.

On the consumer side, stretch has evolved from 'sports-only' to 'daily essential.' The post-pandemic pursuit of comfort and freedom continues, driving tailoring to become stretchy, intimates to become seamless, and activewear to become fashion-forward. Global demand for stretch fabrics is growing 6%-8% annually.

Actionable Advice

For Buyers - Prioritize spandex blends with traceable certifications. Request elastic recovery (≥95%) and residual deformation (≤5%) data. - For stretch jacquards, clarify the ratio of structural to spandex stretch to avoid over-reliance on spandex and premature loss of elasticity. - For 4-way stretch, test multi-directional elongation and recovery, especially dimensional stability after multiple washes.

For Designers - In sportswear and intimates, replace traditional seams with 4-way stretch for a seamless experience. - Use stretch jacquards for localized support, such as waist and side seams, balancing aesthetics and function. - For color and texture, stretch jacquards work best in tonal, three-dimensional effects. Avoid complex prints that obscure structural beauty.

For Mills - Invest in high-precision circular knitting machines and inline tension monitoring. Control yarn feed error within ±2% for stretch jacquards. - Establish dedicated finishing lines for stretch fabrics to avoid high-temperature setting that damages spandex. - Co-develop with spandex suppliers to secure stable supply of bio-based and recycled raw materials.

For Exporters - Prepare in advance for the EU Digital Product Passport: fabric composition, carbon footprint and recycling information. - For North America, highlight cooling and antibacterial functions of 4-way stretch to align with athleisure trends. - Watch regionalized supply chains. Set up stretch weaving and dyeing in Southeast Asia to shorten lead times.

AW26 stretch fabric is where technology, aesthetics and responsibility intersect. Those who balance stretch and recovery will take the lead in the next season's market.
