Swimwear Fabric Guide: Nylon vs Polyester vs Recycled (2026)
This swimwear fabric guide covers the 4 primary options for startup brands: nylon/spandex, polyester/spandex, recycled nylon (Econyl), and recycled polyester (rPET). Swimwear fabric costs $3 to $16 per yard wholesale in Los Angeles, and the fabric you choose determines chlorine resistance, fade resistance, print capability, and sustainability positioning. Choosing the wrong fabric for your price point is one of the most expensive startup swimwear mistakes.

Expert note from the Plucky Reach production team: the most common swimwear sampling failure we see is not the print or the fit, but the fabric losing recovery after the first chlorine soak, which only surfaces once a buyer wears the suit in a pool. We always wet-test and chlorine-soak the approved roll before cutting a production run.
What This Swimwear Fabric Guide Covers: Chlorine Resistance First
A practical swimwear fabric guide starts with chlorine resistance, because that single property decides which fiber and spandex blend your collection needs. Chlorine resistant swimwear fabric is constructed so that the spandex/elastane content maintains its stretch and recovery after repeated exposure to pool chlorine. Standard spandex degrades significantly after 150 to 200 hours of chlorine exposure. The fabric loses elasticity, begins to sag, and fades. Chlorine-resistant spandex (Creora Highclo, LYCRA XTRA LIFE) degrades at 10 to 20% of the rate of standard spandex.
For competitive or frequent-use swimwear, chlorine resistance is essential. For resort or occasional-wear swimwear at $60 to $120 retail, standard nylon/spandex fabric is usually sufficient because most customers wash in freshwater and avoid chlorine pools.
Swimwear Fabric Guide to Chlorine Resistance by Fabric Type
The table below is the quick-reference part of this swimwear fabric guide: match the chlorine resistance level to how your customer will actually use the suit.
Which Swimwear Fabric Should You Choose: Nylon vs Polyester?
Nylon vs polyester swimwear fabric is the most important fabric decision for startup brands, and it is the section of any swimwear fabric guide founders revisit most. The choice affects feel, performance, price point, and which customers you attract.
Nylon/Spandex Swimwear Fabric
Properties: Softer hand feel than polyester, higher stretch recovery, better drape, superior color depth and vibrancy, more UV resistance. The premium choice for fashion swimwear at $80 to $200 retail.
Chlorine resistance: Good to excellent depending on spandex type.
Cost: $5 to $12 per yard for standard colorways. Custom colors: add 30 to 50% for custom dye lots (minimum 50 to 100 yards). Print capability: excellent. Sublimation print on nylon produces vibrant, deep color output.
Best for: fashion swimwear, bikinis, one-pieces with high color story, brands positioning at $80 to $200 retail.
Polyester/Spandex Swimwear Fabric
Properties: Less soft than nylon, quicker-dry properties, excellent sun fade resistance. Polyester does not fade in UV as quickly as nylon. More accessible cost point.
Chlorine resistance: Moderate, adequate for occasional swimwear.
Cost: $3 to $8 per yard. Custom colors: easier and cheaper to achieve in polyester than nylon. Most mills have broader stock colorways.
Best for: casual/resort swimwear, budget collections, brands at $40 to $80 retail.
For both fabric types, swimwear fabric cost per yard wholesale in Los Angeles runs $3 to $12 depending on fiber content. The LA Fashion District hosts multiple swimwear fabric manufacturer Los Angeles wholesale distributors who stock standard swim colorways at 10 to 25 yard minimums, making it accessible for startup quantities before you commit to a full production run.
Nylon vs Polyester: Which to Choose at Each Retail Price Point
Matching fabric choice to retail price point prevents over-investing in material cost at lower price tiers:
Brands at the $35 to $60 price point using premium nylon/spandex will find it difficult to hold margin, particularly at run sizes under 100 units where per-unit cost pressure is highest.

Recycled nylon vs recycled polyester swimwear: both are sustainability credentials, but they perform and position differently, and the sustainability section of a swimwear fabric guide is where most founders overspend without a clear payoff.
Recycled Nylon (Econyl)
Econyl is regenerated nylon made from recovered ocean fishing nets, fabric scraps, and industrial plastic. Properties identical to virgin nylon with the same performance and hand feel. OEKO-TEX and Global Recycled Standard certified.
Cost: $7 to $16 per yard, a $2 to $4 premium over standard nylon. Worth the premium for brands whose customer base actively values sustainability credentials and will pay $20 to $40 more per garment for certified recycled materials.
How to source: Econyl is distributed through specialty performance fabric distributors. In Los Angeles, several fabric wholesalers in the Fashion District carry Econyl in standard swim colorways. Custom colors require larger minimums (100+ yards) through the Aquafil distribution network.
Recycled Polyester (rPET)
rPET swimwear fabric is made from recovered plastic bottles processed into polyester fiber and blended with spandex. OEKO-TEX certified rPET is widely available at accessible prices.
Cost: $3 to $8 per yard, comparable to or slightly above virgin polyester. A more accessible sustainability story for brands at lower price points.
Best for: brands wanting to communicate eco-credentials at accessible retail prices ($45 to $80 swimwear) without the cost premium of Econyl.
What Is the Minimum Order Quantity for Swimwear Fabric?
Swimwear fabric minimum order quantity in Los Angeles: most wholesale fabric suppliers have 10 to 25 yard minimums for stock colorways. Custom dye minimums: 50 to 100 yards for polyester/spandex, 75 to 150 yards for nylon/spandex (higher minimum because nylon dyeing is more expensive per yard at small scale). For a 75-unit swimwear production run, you need approximately 65 to 90 yards of 58-inch fabric, within most wholesale minimums for stock colors.
How Do You Source and Spec Swimwear Fabric for Production?
Getting fabric right before sampling prevents $3,000 to $8,000 in production restarts, so the sourcing steps in this swimwear fabric guide are where the savings actually happen. Here is how to source and specify correctly.
How to Find a Swimwear Fabric Manufacturer in Los Angeles
Swimwear fabric manufacturer Los Angeles options concentrate in two areas. First, the Fashion District wholesale market on Santee Alley and surrounding blocks carries performance swim fabrics from multiple importers at $3 to $14 per yard. You can physically touch and compare fabrics before buying. Second, specialty activewear fabric distributors in the greater LA area carry certified performance fabrics (LYCRA XTRA LIFE, Creora Highclo) and certified sustainable options (Econyl, OEKO-TEX rPET) at slightly higher minimums (25 to 50 yards).
For startup swimwear brands ordering 50 to 150 unit production runs, the Fashion District sourcing route is optimal. Most stalls accept orders from 10 yards, giving you enough fabric to do wash tests and sample rounds before committing to production quantities. Ask each supplier for their OEKO-TEX certificate number if sustainability is part of your brand positioning. Verify it on the OEKO-TEX database directly before making any marketing claims.
Common Mistakes Founders Make When Selecting Swimwear Fabric
Four mistakes account for 80% of swimwear fabric problems at the production stage:
Mistake 1: Choosing fabric by swatch color only. Dry swatches look different when wet and under UV. Always wet-test your final fabric candidates and photograph them in direct sunlight before approving for production.
Mistake 2: Not confirming spandex content percentage. Swimwear requires 15 to 25% spandex for proper stretch and recovery. Fabrics with less than 12% spandex will sag after 20 to 30 wears. Always request the full composition certificate from your supplier.
Mistake 3: Ordering custom dye lots without lead time. Custom nylon dye lots take 6 to 10 weeks. Founders who assume they can dye a unique colorway on a 4-week production schedule miss their launch by 6 weeks every time.
Mistake 4: Using the wrong fabric for sublimation printing. Sublimation requires polyester-heavy fabric. Attempting sublimation on nylon-dominant blends produces washed-out, inconsistent color. If your brand relies on print-forward swimwear designs, confirm the fabric composition before purchasing for a print run.
How to Evaluate Swimwear Fabric Quality Before Production
Five pass/fail criteria for evaluating swimwear manufacturing fabric samples before committing to production quantities:
1. Stretch and recovery: Pull the fabric to 150% in both directions. Release. It should snap back completely in under 1 second. Slow recovery indicates insufficient spandex content.
2. Chlorine soak test: Soak a 6-inch fabric swatch in pool-strength chlorine water (2 to 3 ppm) for 30 minutes. Rinse and dry. Compare the color, stretch, and texture to an unsocked swatch. Degradation after one 30-minute soak indicates low-grade spandex.
3. UV exposure test: Leave a swatch in direct LA sunlight for 48 hours. Compare fade level to a stored swatch. Premium nylon/spandex should show no visible fading. rPET and polyester blends should show minimal fading.
4. Seam strength: Sew a test seam in your intended stitch type. Pull the seam to failure. The fabric should tear before the seam separates. If the seam opens first, the fabric thread count is insufficient for the construction.
5. Hand feel after 5 washes: Machine wash and dry the swatch 5 times. It should feel identical to the original swatch. Any roughening, pilling, or loss of stretch indicates that the fabric will underperform over the product's life.
Frequently Asked Questions
What is chlorine resistant swimwear fabric and do I need it for my brand?
Chlorine resistant swimwear fabric uses specialized spandex (LYCRA XTRA LIFE or Creora Highclo) that maintains stretch and color after 500+ hours of chlorine exposure. You need it for competitive, fitness, or frequent-use swimwear positioned at $80+ retail. For resort or occasional-wear swimwear, standard nylon/spandex fabric that handles 200 to 300 hours of chlorine exposure is usually sufficient.
What is the minimum order quantity for swimwear fabric?
Swimwear fabric minimum order quantities in Los Angeles wholesale: 10 to 25 yards for stock colorways, 50 to 150 yards for custom dye lots (higher minimum for nylon vs polyester). A 75-unit swimwear run requires 65 to 90 yards of 58-inch fabric, within most stock minimums. Plan custom dye orders 6 to 10 weeks in advance of your sampling start date.
How do I source OEKO-TEX certified swimwear fabric?
Source OEKO-TEX certified swimwear fabric through specialty performance fabric distributors in Los Angeles or through your selected manufacturer's fabric sourcing network. Econyl (recycled nylon, OEKO-TEX certified) is available through Fashion District wholesalers in stock colorways. rPET (recycled polyester/spandex) is widely available in certified form from multiple LA wholesale suppliers. Always request the OEKO-TEX certificate number from the supplier and verify it directly on the OEKO-TEX database before marketing certified claims.
