When it comes to stretchable, durable, and highly printable fabrics, few materials compare to the polyester spandex blend. Popular in activewear, athleisure, swimwear, leggings, and performance apparel, this blend combines the best functional properties of polyester and spandex. For designers, brands, and textile printing professionals, understanding how polyester and spandex blends work is essential for choosing the right fabric for your next project.
This guide explores the structure of poly spandex blend fabric, its printing performance, and the various types of polyester-spandex fabrics used in modern apparel manufacturing.
1. What Is a Polyester Spandex Blend?
A polyester spandex blend is a fabric created by combining polyester (usually 85–95%) with spandex (5–15%). Polyester contributes durability, color retention, wrinkle resistance, and moisture-wicking properties, while spandex provides stretch and flexibility.
For a deeper look into the science behind polyester fibers, Britannica offers an excellent overview:

Common blend ratios:
95% polyester / 5% spandex
90% polyester / 10% spandex
88% polyester / 12% spandex
Common uses include:
Yoga leggings
Sportswear
Cycling suits
Swimwear
Dancewear
Fashion and athleisure
Kids clothing
2. Key Features of Polyester & Spandex Blend Fabrics
The polyester and spandex blend offers a unique mix of performance qualities:
✔ Stretch & Recovery
Spandex gives the fabric 2-way or 4-way stretch, ensuring it returns to its original shape after movement.

✔ Vibrant Print Quality
Polyester holds color exceptionally well during sublimation, making prints vivid and fade-resistant.
✔ Durability & Shape Retention
These fabrics withstand repeated washing and intensive use, maintaining structure over time.
✔ Breathable, Moisture-Wicking, and Quick-Drying
Polyester efficiently manages moisture, making the blend ideal for athletic garments.

3. Why the Polyester Spandex Blend Is Ideal for Custom Printing
One reason polyester spandex fabrics dominate the custom printing world is their compatibility with sublimation printing.
According to Printful, sublimation works best on polyester-rich fabrics because the dye bonds directly with polyester molecules:
