For swimwear factories and OEM suppliers, understanding the proper care of swimwear—including whether garments can withstand the heat and agitation of a dryer—is crucial for developing products that satisfy both retail partners and end consumers. This article explores the science behind swimwear fabrics, the impact of modern dryers, global brand recommendations, and practical guidance for maximizing swimwear longevity. Whether you are a brand, wholesaler, or consumer, this comprehensive analysis answers the essential question: can you put swimwear in the dryer?
Modern swimwear is engineered for stretch, support, colorfastness, and durability—yet it relies heavily on synthetic materials. The principal fibers used are:
- Nylon (Polyamide): Lightweight, abrasion-resistant, and fast-drying, but sensibly vulnerable to prolonged heat, chlorine, and UV exposure.
- Polyester: Known for its excellent color retention and high chlorine resistance. It endures more exposure to chemicals but is still sensitive to high heat.
- Spandex (also called Lycra or Elastane): Provides stretch and resiliency, responsible for the snug fit and shape recovery that swimwear is prized for. Spandex is the most sensitive to heat, as its molecular structure breaks down rapidly at elevated temperatures.
Blends of these materials are used to balance comfort and lifespan, but none are truly immune to the damaging effects of a tumble dryer.
Besides fabric composition, swimwear construction is specialized. Seam placements, reinforced stitching, crotch linings, and bonded panels are all designed to withstand movement in water—not mechanical agitation or the dryer's high temperatures.
The tumble dryer's primary threat comes from heat. Most domestic dryers operate at temperatures above 50°C (120°F). For swimwear, heat brings multiple risks:
- Elasticity Loss: Spandex/elastane fibers lose their shape and strength, often permanently, after repeated exposure to high heat. This causes sagging, bagginess, and loss of fit.
- Melting or Shrinking: The molecular arrangement of both nylon and polyester can be altered by heat, leading to subtle melting, shrinking, or permanent distortion.
- Bond and Seam Failure: The glue or bonded seams in technical or high-performance swimwear can soften or break down under dryer heat, reducing their integrity.
Tumble dryers work not just through heat, but by tossing garments. This mechanical action:
- Introduces friction, causing surface abrasion or pilling (small fuzz balls) on smooth swim fabrics.
- Stresses seams and stitches, especially around straps and bands designed for compression support.
After a swim, it's common for some chlorine, salt, or sunscreen residue to remain. The heat of a dryer can set these chemical traces into the fabric, making them harder to wash out and accelerating color fading or fiber stiffness.
Vibrant swimwear colors and prints are particularly susceptible to cumulative fading when dried with heat. Multiple cycles can dull bold shades and bleed multi-color patterns.
All major swimwear manufacturers and global brands recommend air drying as the gold standard for preserving performance and appearance. Here's the right way:
1. Rinse Immediately: Always rinse your suit with fresh, cool water after swimming to remove chemicals and salt that break down fabric.
2. Gently Squeeze: Remove excess water using a light press in a clean towel—never twist or wring out the fabric, which can distort and damage delicate fibers.
3. Lay Flat to Dry: Lay the swimsuit flat, ideally between two dry towels or on a mesh drying rack, in a shaded area away from direct sunlight.
4. Flip Midway: Turn the garment halfway during drying for even moisture removal.
5. Hang with Care (if needed): Hanging by the thickest part (such as the waistband or under-bust band) is better than by the straps, which may stretch out.
- Never use the dryer (tumble dry), even on a low or air cycle.
- Don't hang swimwear in direct sunlight for extended periods, as UV rays can fade dyes and accelerate fabric degradation.
- Don't use radiators, heaters, irons, or hair dryers on swimwear.
- Don't use fabric softener or harsh detergents when washing, as these can leave residues or harm elasticity.
The unique polymers that give swimwear fabric its bounce and shape—particularly Spandex/elastane—are composed of long chains that align and stretch repeatedly when worn. Excessive heat relaxes, then breaks, these chains at the molecular level, which is why suits become saggy, thin, or frayed.
Polyester and nylon can tolerate heat a bit better, but repeated hot cycles alter their surface, making them look worn and compromised in structural performance.
Some modern dryers offer “delicate,” “air fluff,” or “low heat” settings. While these are less destructive than full-heat cycles, even the lowest agitation and mild warmth increase the deterioration rate of elastic fibers. Over time, the cumulative effect will shorten your swimwear's life.
Occasionally, circumstances might make tumble drying tempting—a last-minute need for a dry suit, limited space, or a cold climate. If absolutely necessary, select only the no-heat “air fluff” cycle and remove the garment while it remains slightly damp. Know, however, that even this method increases the risk of premature aging and performance loss.
Air drying is not only better for swimwear, but also for the environment. Dryers are among the most energy-consuming household appliances. Encouraging natural air drying supports sustainability and can be a valuable selling point for eco-focused consumers.
- Labeling: Always mark swimwear care tags with clear instructions—“Do Not Tumble Dry”—in multiple languages.
- Consumer Education: Include care cards with every shipment and publish digital aftercare guides on both brand and retail platforms.
- Packaging: Use packaging that does not trap moisture (which could encourage mold) but protects elasticity and color.
- Quality and Testing: OEM partners should test their fabrics and constructions regularly for resistance to heat and agitation, but never market swimwear as "dryer-safe" unless independently verified to standards beyond mainstream performance requirements.
1. Using the dryer just occasionally won't hurt: Even one or two cycles can damage delicate elastic fibers and finish, especially in premium or highly elastic suits.
2. You can “shrink back” a stretched suit with heat: Heat-damaged elastic fibers lose, not regain, their resilience. Results are nearly always negative.
3. Children's or basic suits are more durable: Children's swimwear is made with the same or similar synthetic blends and suffers the same fate as adult suits when tumble dried.
| Drying Method | Pros | Cons |
|---|---|---|
| Air Dry (Flat) | Preserves shape, color, elasticity; energy free | Takes longer; needs flat, ventilated space |
| Hanging (Shaded) | Easy, space-saving | Potentially stretches straps, uneven drying |
| Dryer (Any Heat) | Fast, convenient | Destroys elasticity, fades color, risks deformation |
| Dryer (Cool/Air Only) | Faster than air, less risk | Still risks fiber stress and long-term damage |
| Direct Sun | Fast, natural sanitizer | Causes fading and weakens polymers |
To get the most out of swimwear, especially investment or technical pieces, adhere to this strategy:
- Alternate suits: Allow each to rest between uses, restoring their elasticity.
- Rinse, don't soak: Avoid prolonged soaking in harsh detergents or hot water.
- Store flat: Prevents unwanted stretching or deformation of cups and waistbands.
- Address stains early: Spot clean sunscreen or chlorine buildup with gentle solutions rather than repeated washing.
- Make swimwear care education a part of packaging, online product pages, and after-sales messaging.
- Incorporate QR codes on labels linking to care videos or guides.
- Train in-store staff to explain air drying benefits and answer care queries.
High customer satisfaction with swimwear longevity translates directly into brand loyalty, stronger reviews, and more repeat business.
Technical swimwear—like racing suits or those with bonded fabric surfaces, compression technology, or advanced prints—are even less tolerant of dryers. Their unique performance characteristics can be ruined by a single incorrect drying cycle, making heat-based drying even riskier for these products.
With sustainability as a market driver, more brands are developing recycled-fiber swimwear and encourage eco-friendly care practices. Dryer use not only consumes unnecessary energy but also shortens the life of garments intended to be durable, undermining both environmental and economic efficiency.
- Leaving wet swimwear bundled in a gym bag, which can cause odor and mildew.
- Scrubbing vigorously or machine-washing on a heavy cycle, which may stretch or tear fibers.
- Using high-alkaline detergents or bleach, which degrade synthetics and accelerate breakdown.
- Ironing swimwear, which immediately destroys heat-sensitive fibers.
You should never put swimwear in the dryer. High temperatures and mechanical action destroy the very fibers, prints, and fit that make swimwear comfortable, supportive, and vibrant. Air drying, away from both heat and direct sun, is always the preferred method—for consumers, brands, and manufacturers alike. Careful drying extends garment life, maximizes customer satisfaction, and reinforces the value proposition of every swimwear purchase.
No. Whether basic, premium, or children's suits, nearly all swimwear is adversely affected by tumble drying—especially those containing spandex or elastic blends.
Air drying preserves elasticity, color, and fit, while a dryer's heat and friction irreversibly break down fibers and cause sagging, dullness, and deformation.
One cycle can compromise elasticity, especially in high-end or technical swimwear. Cumulative damage is even more likely with repeated use.
Gently press out water with a towel and lay flat in a ventilated, shaded space. Avoid heat and direct sun. If speed is essential, use a fan to increase air flow.
No. Radiators and heaters can reach high localized temperatures, causing immediate damage to elastic and synthetic fibers, similar to a dryer.
