Trend Observation

For AW26, stretch fabrics are no longer just about adding spandex. At fabric fairs from Milan to Shanghai, spandex blends are undergoing a quiet revolution: bio-based spandex (such as corn-based PTT) blended with recycled polyester is rising significantly, and low-temperature setting allows stretch fabrics to achieve stable recovery at 130°C, cutting energy consumption by about 20%. This is not just an eco narrative but a rebalancing of cost and performance.

Stretch jacquard is another breakout track. The combination of double-sided jacquard machines and high-elastic core-spun yarns keeps patterns clear and undistorted after stretching. Three-dimensional rib jacquards on sports jackets provide localized compression while retaining design appeal. In intimates, ultra-fine stretch jacquards are popular, using yarns below 40D to weave lace-like breathable holes while offering 4-way stretch coverage.

4-way stretch itself is evolving. Traditionally dependent on spandex, it now achieves mechanical stretch without spandex through bicomponent composite yarns and special knit structures. These fabrics maintain over 95% recovery after repeated stretching and are more resistant to chlorine, suitable for swimwear and high-intensity training. Fluorine-free water repellency combined with stretch has become a new favorite for outdoor sports brands.

Industry Impact

The low-temperature setting of spandex blends directly impacts dyehouses and setting mills. Previously, stretch fabrics required high-temperature setting; now low-temperature processes not only save energy but also reduce spandex heat damage, extending fabric life. This means factories need to upgrade setting equipment or adjust auxiliary formulas, or risk losing high-end orders.

The popularity of stretch jacquard has driven up demand for double-sided jacquard machines. Many domestic factories are purchasing high-gauge jacquard machines to produce finer patterns. However, combining jacquard with stretch places strict demands on yarns: the covering degree of spandex core-spun yarn must be uniform, otherwise white spots appear after stretching. This forces yarn suppliers to improve quality and raises procurement thresholds.

The cross-penetration of 4-way stretch in sports and intimates blurs category boundaries. Sports bras need 4-way stretch for support while requiring skin-friendliness and breathability; shapewear seeks high recovery and seamless effects. This pushes fabric mills to develop "one fabric, multiple uses" solutions, such as the same 4-way stretch fabric for yoga pants and sports bras. In foreign trade, demand for fluorine-free water-repellent stretch fabrics is surging in European and American brands, but testing standards are tightening, requiring exporters to secure certifications in advance.

Practical Advice

For Buyers - Prioritize bio-based spandex blend fabrics, look for low-temperature setting certifications, and calculate total lifecycle cost rather than unit price. - Require suppliers to provide stretch recovery test reports (e.g., ASTM D2594) and clarify elasticity retention after washing. - For sports and intimates, request chlorine resistance and skin-friendly test data separately to ensure fabric suitability.

For Designers - Try localized stretch jacquard in sports jackets, using patterns to guide compression zones instead of traditional splicing. - For intimates, choose ultra-fine stretch jacquard, using breathable holes and lace effects to replace traditional lace, enhancing comfort. - 4-way stretch fabrics can be used for dart-free designs, leveraging stretch to fit the body, reducing seams, and improving freedom of movement.

For Factories - Invest in low-temperature setting equipment or retrofit existing setting machines to secure high-end stretch fabric orders. - Jointly develop uniformly covered spandex core-spun yarns with yarn suppliers to solve jacquard white spots. - Establish dedicated quality inspection processes for stretch fabrics, focusing on recovery, weight, and width stability.

For Traders - For European and American markets, prepare bluesign or OEKO-TEX certifications for fluorine-free water-repellent stretch fabrics in advance. - Monitor tariffs and rules of origin for bio-based spandex, and optimize supply chain layout. - Offer customers "stretch + function" combination solutions, such as 4-way stretch + antibacterial + fluorine-free water repellency, to increase premium space.
