Factors to Consider When Choosing Materials for Swimsuits
Before deciding which type of swimwear fabric to sell to your customers, there are some things to consider.
These factors will also help you choose the right private label swimwear manufacturer in case you’re launching a brand.
Here’s what you should look out for:
1. Composition
Swimsuit fabrics typically consist of blends that combine durability, stretch, and moisture-wicking properties. The most common materials include nylon, polyester, and spandex (elastane).
Nylon and polyester blends are popular due to their strength and quick-drying characteristics. These synthetic fibers often make up 80-90% of the fabric composition, with spandex accounting for the remaining 10-20%.
Spandex provides crucial elasticity, allowing your swimsuit to stretch and retain its shape. This ensures a snug, comfortable fit that moves with your body in the water.
Some high-performance swimwear incorporates specialized blends:
- Chlorine-resistant fabrics (up to 100% polyester)
- UV-protective materials
- Recycled polyester and spandex blends for eco-friendly options
The fabric weight also impacts performance and comfort. Most swimwear ranges from 180-200 grams per square meter (gsm).
Lighter fabrics (around 150 gsm) feel more like lingerie, while heavier options (200-220+ gsm) suit competitive swimming or textured designs.
When choosing your swimsuit, consider how the fabric composition affects:
- Durability: Higher nylon or polyester content increases longevity
- Comfort: More spandex provides greater flexibility
- Quick-drying: Synthetic blends dry faster than natural fibers
- UV protection: Some fabrics offer built-in sun protection
By understanding these fabric properties, you can select a swimsuit that best meets your needs for style, comfort, and performance.
2. Colorfast
When choosing swimwear, colorfastness is a crucial factor to consider. It determines how well your swimsuit maintains its vibrant hues despite exposure to chlorine, saltwater, and UV rays.
Colorfast fabrics resist fading and running, keeping your swimsuit looking fresh for longer. You’ll want to look for swimsuits with excellent colorfast properties to ensure your beachwear stays bright and attractive.
Industry standards for testing colorfastness include:
- AATCC Test Method 61: Colorfastness to Laundering
- ISO 105-E03: Colorfastness to Chlorinated Water
These tests simulate real-world conditions to evaluate how well swimwear fabrics retain their color.
When sourcing swimwear, check the label for colorfast claims. Many high-quality swimsuits use specially treated fabrics or dyes that resist fading.
You can also look for swimwear made from recycled nylon or polyester, which often have excellent colorfastness.
Remember, proper care can help maintain your swimsuit’s color. Rinse it in cold water after each use and avoid leaving it in direct sunlight when not in use.
This will help preserve the vibrant colors you love, keeping your swimwear looking great season after season.
3. Weight
The weight of swimsuit fabric plays a crucial role in comfort and performance. Most fashion swimwear fabrics range from 180-200 g/m². This weight strikes a balance between durability and lightweight feel.
Lighter fabrics, around 150 g/m², feel more like lingerie. They’re great for lounging but may not hold up well during active swimming.
Heavier fabrics, weighing 200-220 g/m² or more, are better suited for competitive swimming. These materials offer more support and durability for intense water activities.
Neoprene, used in wetsuits, is on the heavier end. It provides excellent insulation but may feel bulky for casual swimming.
Remember, fabric weight affects how quickly your suit dries. Lighter materials typically dry faster, which is handy for frequent swimmers.
Your ideal swimsuit weight depends on your activities. A lightweight suit offers freedom of movement for casual beach days. A heavier fabric provides more coverage and support for water sports.
4. Elasticity
Elasticity is crucial for your swimsuit’s performance and comfort. Spandex, also known as elastane or Lycra, is the star player in providing that essential stretch.
You’ll find spandex makes up about 10-25% of most swimsuit blends. This synthetic fiber offers exceptional elasticity, allowing your suit to hug your curves and move with you.
Why does elasticity matter so much? It ensures:
- A snug, body-contouring fit
- Freedom of movement in the water
- Shape retention over time
When you’re swimming laps or diving into waves, you need a suit that stretches with you. Elastic materials prevent uncomfortable binding or riding up as you move.
Rubber elastic is another top choice for swimwear. It maintains tension well and resists chlorine, salt water, and UV rays.
Remember, a suit with good elasticity will bounce back to its original shape after wear. This means it’ll look great and fit perfectly, swim after swim.
When sourcing, give your potential new suit a gentle stretch. Quality elastic materials should snap back quickly, promising lasting performance in the water.
4. Durability
When choosing swimsuit materials, durability is key. You want a suit that can handle chlorine, salt water, and UV rays without falling apart.
Polyester is a top choice for durability. It resists chlorine and maintains its shape even after frequent use. Many competitive swimmers opt for polyester suits due to their longevity.
Spandex and Lycra blends also offer excellent durability. These materials retain their shape and elasticity over time, ensuring your suit fits well swim after swim.
Manufacturers often use a “rub test” to test durability. This simulates wear and tear by rubbing the fabric against itself or other materials. A high-quality swimsuit should withstand at least 20,000 rubs without showing significant signs of wear.
UV resistance is another crucial factor. Look for materials with built-in UV protection to prevent fading and degradation from sun exposure. Some fabrics can block up to 98% of harmful UV rays.
Remember, proper care extends your swimsuit’s life. Rinse in cool water after each use and avoid machine drying. With the right material and care, your swimsuit can last for 100+ wears or more.
5. Cost
The price of swimwear varies widely based on the materials used. High-performance fabrics like spandex and Lycra tend to be more expensive, impacting the overall cost of your swimsuit.
Premium swimwear made with these materials can range from $50 to $200 or more. These fabrics offer superior stretch, durability, and comfort, justifying their higher price point.
More affordable options often use polyester blends. You can find polyester swimsuits for as low as $20 to $50. While less expensive, they may not last as long or provide the same level of performance as pricier alternatives.
Neoprene swimwear falls on the higher end of the price spectrum. This thick, insulating material is commonly used in wetsuits and can cost $100 or more for a swimsuit.
When choosing a swimsuit material, consider your budget and intended use.
If you’re catering to frequent swimmers or those who need high performance, investing in a more expensive suit might be worthwhile. For occasional users, a more affordable option could suffice.
Remember, proper care can extend the life of your swimsuit regardless of its cost. Always rinse after use and hand wash with mild detergent to maintain its quality and appearance.
6. Sustainability
Swimwear sustainability has become a hot topic in recent years. You might be surprised to learn that many swimsuits are now made from recycled materials. These eco-friendly options not only look great but also help reduce waste.
