Buying Guide: Choosing Stretch Fabric for Swimwear
Not all stretch fabrics are equal. Here is what to look for when sewing swimwear:
- 4-way stretch is non-negotiable: Swimwear must stretch in both directions (lengthwise and crosswise). 2-way stretch fabrics will restrict movement and feel uncomfortable in the water.
- Nylon vs polyester base: Nylon spandex has a smoother hand feel and better drape, making it ideal for swimsuits. Polyester spandex is more durable in chlorinated pools but has a slightly rougher texture.
- Spandex percentage: Look for 15-20% spandex content. Less than 15% will not have enough recovery; more than 20% can feel too tight and is harder to sew.
- Recovery test: Stretch the fabric and let go. Good swimwear fabric should snap back instantly with no distortion. If it stays stretched, it will sag when wet.
- Weight: Swimwear-weight nylon spandex is typically 6-8 oz/yd². Lighter weights work for competition suits; heavier weights work for active surfing.
Sewing Tips for Stretch Fabric
- Use a ballpoint or stretch needle to avoid snagging the fibers
- Sew with a zigzag stitch or stretch stitch — a straight stitch will pop when the fabric stretches
- Use polyester or wooly nylon thread for seams that stretch with the fabric
- Consider a serger for clean, professional-looking seams
Frequently Asked Questions
What fabric is swimsuit material made of?
Most modern swimsuits are made from nylon spandex (also called nylon lycra). The typical blend is 80 percent nylon and 20 percent spandex. This combination provides 4-way stretch, chlorine resistance, and quick-dry properties.
Is nylon spandex chlorine resistant?
Yes. Nylon spandex resists chlorine degradation much better than cotton or polyester blends. It maintains its stretch and color even after repeated pool use. For maximum lifespan, rinse your swimwear in fresh water immediately after swimming.
How much stretch should swimwear fabric have?
Swimwear fabric should stretch at least 50 percent in both directions and recover to its original size. This is called 4-way stretch. Our nylon spandex fabrics have 75 percent or more stretch with full recovery.
