Swimwear Fabrics & Linings: What Designers Should Know
Compare nylon vs polyester vs spandex blends, choose the right lining, validate chlorine/UV performance, and pick eco materials and print methods that last.
Core Fibers & Blends
Fiber/Blend | Strengths | Use Cases |
|---|---|---|
Nylon/Spandex | Soft hand, great drape, vibrant prints | Fashion swim, bikinis, one-piece |
Poly/Spandex | Better chlorine/UV resistance, shape retention | Training, resort pools, kids |
High Spandex (20%+) | Superior stretch & recovery | Compression, performance lines |
Linings & Comfort
Prioritize opacity when wet, breathability, and soft hand. Common lining choices include nylon tricot, poly tricot, and power mesh for support panels.

Chlorine & UV Performance
Lab tests should validate colorfastness and stretch recovery. Polyester-dominant blends usually outperform nylon in chlorinated pools and high UV exposure.
Eco Materials & Certifications
Recycled nylon (e.g., pre/post-consumer)
Recycled polyester with GRS claims

Printing & Dyeing for Longevity
For crisp graphics, sublimation on poly blends excels. For deep saturated colors on nylon, ensure heat profiles and pre-treatment are dialed in. Always confirm wash/bleed resistance in pre-production.
Logo Techniques & Cost Impact
Process | Look/Feel | Durability | Cost Level | Production Comment |
|---|---|---|---|---|
Screen Print | Bold solids | High | 💸 Low–Medium | Most economical for large production runs; costs increase for multi-color or small batches. |
Heat Transfer | Clean edges for small logos | High | 💸💸 Medium | Suitable for complex designs or small batches; materials and process are slightly more expensive than screen printing. |
Embroidery (select areas) | Premium tactile | Very High | 💸💸💸 High | Highest cost due to time, machine work, and thread materials. |
Care & Longevity Tips
