Top Fabrics for Swimsuits Guide Best Materials for Making Swimwear

Swimsuit Industry Growth and Why Fabric Choice Matters

The swimsuit industry is booming, expected to surpass a staggering $34.2 billion by 2031. Whether you’re launching a new swimwear line or expanding an existing product range, selecting the right fabric is critical to your success.

Swimwear fabrics must meet unique demands for performance, comfort, durability, and style. Let’s dive into the 7 best fabrics for making swimsuits to help you find the perfect material for your collection.

What Makes a Great Swimsuit Fabric?

Swimwear fabric can’t just look good—it needs to perform. The ideal material is lightweight, flexible, and stretchy for freedom of movement in water, while providing solid support. After swimming, it must dry quickly to keep the wearer comfortable.

Resistance to chlorine, UV rays, and color fading is vital due to constant exposure at pools and beaches. Finally, modern consumers increasingly value sustainability and ease of maintenance. Balancing all these qualities can seem daunting, but certain fabrics rise above the rest.

1. Polyester

Polyester is a staple fabric in swimwear for good reasons. Its resilient fibers stand strong against chlorine and UV damage, so polyester swimsuits maintain shape and color even after repeated wear.

Water resistance gives it fast-drying capabilities, and its excellent dye absorption unlocks endless design possibilities. For new swimwear brands, polyester offers an affordable yet high-performance choice.

2. Polybutylene Terephthalate (PBT)

PBT is a specialized type of polyester that stands out for its natural stretch comparable to Lycra. It’s lightweight, fast-drying, and highly resistant to chlorine, snagging, and pilling—common issues reducing swimsuit comfort and lifespan.

These qualities make PBT an excellent choice for swimwear designed to withstand intensive use.

3. Nylon

Nylon has long been a swimwear favorite due to its lightweight feel, smooth texture, abrasion resistance, and affordability. It dries quickly and provides a comfortable fit, enhancing swimmer mobility.

However, nylon lacks polyester’s colorfastness and can fade with sun exposure. Printing on nylon may also blur, so it’s best suited for solid colors or minimal design details.

4. Neoprene

For thicker, insulating swimwear like wetsuits, neoprene—a type of rubber—is unmatched. It excels at retaining warmth, ideal for cold-water activities such as diving or surfing, helping brands serve niche markets.

5. Scuba

Often confused with neoprene, scuba fabric lacks the inner insulating foam layer. Though unsuitable for cold water, its structure, resilience, and opacity make it perfect for more modest and fashion-forward swimwear designs.

6. REPREVE

7. ECONYL

ECONYL is another eco-conscious choice made by regenerating nylon waste from oceans and industrial sources. This closed-loop system recycles nylon back to pure fiber, reducing environmental impact.

Swimsuits crafted from ECONYL are soft, breathable, stretchy, and quick-drying, providing both high performance and sustainability benefits.
