Trend Observation
In AW 2026, stretch fabrics are evolving from a 'functional sidekick' to a 'design protagonist'. Consumers' understanding of comfort has moved beyond simple physical stretching, seeking 'memory elasticity' that conforms to the body yet recovers its shape, without sagging after prolonged wear. Thus, spandex blending technology is undergoing refined upgrades: no longer merely adding spandex for stretch, but precisely balancing elasticity and hand-feel by altering fiber cross-sections (e.g., cross-shaped, hollow) and blending ratios (e.g., with recycled nylon or bio-based polyester).
Stretch jacquard stands out as a process highlight this season. By combining jacquard looms with elastic yarns, fabrics develop three-dimensional textures during weaving, offering localized compression (e.g., waist and abdomen support) while adding visual layering. This is especially prominent in sports compression wear and shaping undergarments—elasticity is no longer uniform but zoned, meeting different support needs across body regions.
Four-way stretch technology is also penetrating from high-end activewear into the mass market. Unlike traditional two-way stretch (single-direction elongation), four-way stretch uses special weaves (like honeycomb mesh or diamond grids) or elastic core-spun yarns to achieve high recovery rates (≥85%) in both warp and weft directions, with independently designable elastic moduli. This provides a 'zero-restraint' experience for leggings and running tights.
Industry Impact
Stretch fabric innovation is reshaping supply chain logic. On one hand, sustainable alternatives to spandex are in focus—commercial bio-based spandex (e.g., Lycra's) and recycled spandex exist, but costs are still 15%-20% higher than traditional ones. This prompts brands to adopt differentiated strategies: high-end lines emphasize 'lower carbon footprint', while mass-market lines rely on bulk procurement to dilute costs.
On the other hand, stretch jacquard and four-way stretch demand higher-performance weaving equipment. Utilization rates of high-speed electronic jacquard and warp knitting machines become critical, requiring factories to balance flexible production with batch efficiency. Moreover, testing standards for stretch fabrics (like ASTM D4964) are being replaced by more dynamic tests that simulate multi-directional stretching and fatigue under real wear, driving collaborative development of new methods among testing institutes and fabric companies.
At the category level, the boundary between sportswear and intimates blurs. Sports bras and seamless active bodysuits require fabrics to simultaneously offer support, breathability, and elastic recovery. This compels fabric companies to shift from 'selling cloth' to 'selling solutions'—providing one-stop collaborative development from yarn selection, weave design, to finishing (e.g., moisture wicking, antibacterial).
