Introduction
It is extremely important to select the right fabric for your swimwear as it affects performance, comfort and durability. Swimwear not only has to withstand the elements of water but must remain uniform, bright and comfortable after many washings. As you can see, swimwear is made from various types of materials over the years and all have their advantages. Of all these, nylon is the most used and productive choice to make durable swimwear. Nylon, which is water repellent, tough and pliable, is now the choice for recreational and competitive swimwear.
In this article we are going to discuss the reason why you often see nylon fabrics in swimwear – because it is water resistant and strong. So let’s see what nylon can do for comfort, performance and look over the long term, in water, where it really is a real challenge. By looking at how nylon works physically and reacts to water and external environments, we will get a complete picture of why nylon is still a ubiquitous fabric for swimwear.
1. Understanding Nylon Fabric
Synthetic Polymer & General Properties of Nylon
Nylon is a synthetic polymer and belongs to the polyamide group. The name was created by the American chemist Wallace Carothers in 1935 under the name “DuPont”. Carothers’ creation of nylon was the first mass-produced synthetic fibre, and changed the textile industry. Nylon today is one of the most diverse and popular fibres on the planet, with applications in clothing and jewellery to textiles for use in the factory and swimwear.
It’s a chemical reaction called polymerization that forms nylon fibres from interacting molecules into long chains. This construction is what makes nylon so strong, flexible and tough. Nylon is more light than natural materials such as cotton or wool and is sturdier, has a very low tendency to stretch and is highly resistant to wear and tear. It is also a very comfortable fabric, that does not wrinkle and fade, so it’s a great fabric for any use such as swimming costumes.
The Explosion of Nylon Fabric in Fashion and Swimwear.
With the mid-20th-century introduction of nylon into clothing and textile manufacturing, clothing and accessories — including swimming costumes — took another turn for the better. Because nylon was fast-drying, lightweight and waterproof, it was an ideal material for swimwear. Nylon was taking over the swimwear industry in the 1950s and ’60s because it is both more robust and practical than cotton.
Nylon is often combined with other fabrics now – like spandex or elastane – to make it stretchy, making it even better for a figure-hugging swimsuit design. It’s that — durability, suppleness, resistance to water and breathability — that has kept nylon in swimwear, from elite racing apparel to the average casual beach cover-up.
Why is Nylon The Right Material For Swimwear?
Nylon has the set of physical properties for swimmingsuit use:
- Lightweight: It must be light so that you will have a comfortable ride on the water without getting suckered. There is also no bulk to nylon and that is perfect for swimsuits.
- Comfort: When used with spandex, nylon has a lot of stretch. It’s so tight and yet it feels good in your skin and goes with your body as you exercise underwater.
- Easy-dry: This is the main advantage of nylon, which is easy to dry. When wet, nylon absorbs little water and it drys quicker than other materials, so you are comfortable once you are out of the water.
Such basic properties are why nylon is not only practical but also very apt for swimwear made to work in any weather condition, from backyard fun to pro sports.
2. The Water Proofness of Nylon for Swimwear.
Inherent Water-Repellent Properties of Nylon
Another main reason why nylon is popular for swimming is because it is waterproof. There’s a slick finish to nylon fibers which repel water unlike other fabrics such as cotton which retain moisture. Because nylon molecules are so dense, they don’t hold water very well, so the fiber absorbs less water and dries more quickly. This water repellant is particularly useful in swimsuits as it makes the fabric float on top of your body and keep its form, even when wet.
It is also thanks to the extremely tightly knit nylon fibres that it is water resistant, since water doesn’t penetrate deeply into the fabric. That’s an important point over cotton or wool, for example, which retain water, making them bulky, uncomfortable and slow to dry. Thus, nylon swimming clothes help the swimmers remain light and mobile while swimming, and the material is quick drying out of the water.
How Water-Repellent Coatings Make Nylon for Swimwear Splash Proof?
Depending on which type of clothing you’re wearing, most swimwear companies coat nylon with specialised chemicals to make it more water resistant. Polyurethane (PU) or silicone can also be layered on nylon fibers at the factory to make them even more waterproof. These coatings obstruct the surface of the fabric so water can’t get into the fibres, allowing the fabric to keep dry.
This treatment is particularly important for swimwear that is worn in rough environments like outdoor swimming in freshwater bodies of water or extreme weather. All of the extra coatings keep the swimming wear water repellent and preserve its strength to resist any harm if exposed to moisture for extended periods of time.
Water Resistant of Nylon When Wet.
The water repellent (hydrophobibic) aspect of nylon swimwear means it’s not the same fabric in a wet environment. Nylon doesn’t shrivel and crack in water, as cotton does and gets squiggly and hefty in water. Swimming suits made of nylon evaporate quickly since it evaporates water very quickly so the fabric does not dry out.
This is very useful for swimmers as it avoids irritation due to the sticking of wet fabrics and keeps the swimwear in its intended form and function during water sports. Also, nylon’s anti-water retention minimises chafing and irritation from wet fabrics touching skin.
3. Durability of Nylon in Swimwear
Strength and Resilience
The fabric of nylon is also very durable, which is a fantastic fabric for swimming suits that are used over and over again, handled rough, and exposed to chlorine and salt water. This is because the nylon fibers can be tensile tested, which means that a swimsuit made of nylon can withstand substantial wear and tear without loosing shape or texture.
For example, nylon swimming suits won’t rip, stretch or fade like cotton or polyester versions. Its molecular attachments enable the fibre to be relatively resistant to wear, even in conditions of endless churn in the water, or friction during the repetition of the swimming person entering and exiting the water. That makes nylon swimwear a must-have for competitive swimmers who need clothes that can endure repeated training and hours of pool time.
Resistance to Wear and Tear from Chlorine, Saltwater, and UVA/UVB Sunlight.
Nylon swimwear also stands up to chlorine, saltwater and UV rays, which all damage other materials. Usually chlorine from swimming pools renders fabrics brittle and lose their stretch. But nylon fibers are especially tough against chlorine — they don’t shrink or wrinkle after hours in chlorinated water.
Likewise, chlorine bleach is destructive to swimwear materials, yet nylon’s sturdiness ensures it does not degrade in seawater. Another problem with swimmingwear is the UV damage and fibre brittleness. There are UV-protected finishes applied to nylon that will maintain its colour and durability when left out in the open to the sun for extended periods. That resistance to the environment is what keeps nylon bathing costumes functional and stylish after years of swimming in a wide variety of water conditions.
Resistance to Stretching and Deformation
Nylon is one of the softer materials and it can stretch back to its original shape without getting stiff. This is a crucial feature for swimwear which has to stay in place so that it fits swimmers snugly. And unlike fabrics that may loosen or wrinkle once wet, nylon swimming costumes will return to the shape they started with when dry, so you’ll never experience sagging or unfitting.
The nylon is durable, flexible, and resists wear well. This is a key quality for the clothing that you are wearing often (for example, for training, competition or daily swimming).
4.Comfort and Function of Nylon Swimwear.
Comfort and performance are two things swimmers and beachgoers have to consider when they choose their swimwear. Be it beach laying to competitive swam, fabric dictates the whole experience. This is probably the most popular and popular fabric for swimwear; nylon. It is a thin, stretchy material that offers many performance advantages and it has been the most common type of material in swimmingwear. This page details the role of nylon for comfort and performance, such as breathability, elasticity, quick-drying and how it stacks up against other materials such as spandex and polyester for swimming.
1. Breathability and Flexibility
Nylon’s Breathability in Swimwear
Breathability means that fabric has the capacity to allow for airflow so that the body stays cool, without getting hot. It is especially necessary for swimwear, which is in constant contact with water, heat and moisture.
This is mainly because the fabric and texture of nylon swimwear is highly breathable. Nylon fibres are small and tightly twisted so the fabric is soft and effectively wicks away moisture. If you’re swimming, the fabric wicks sweat and moisture so you stay dry and cool while you’re doing it. This is especially helpful for people who do a lot of swimming, both in a pool and on the sea.
What’s more, nylon is also very breathable, and it helps keep you cool in the summer. Swimwear that are breathable keeps the fabric from getting too hot and sticky when you’re at the beach or engaged in watersports. Nylon’s lightness lets air flow, which means that it won’t hurt the swimmer while she’s laying out in the sun and swimming in the water for hours. The latter is true of anyone who’s in the water for extended periods, like surfers, swimmers or those involved with water aerobics.
On the other hand, non-traditional fabrics such as cotton (less used for swimwear) tend to keep water, which causes you to feel ill and take longer to dry. Cotton also wicks away water and sweat, making the swimmer wet and slow. This is avoided by the breathability of nylon which keeps you cool and dry even when you spend a long time out in the water and sun.
Nylon’s Flexibility for Comfortable Movement
Swimwear that’s flexible means that the material will move with you to make you feel good in any swimming situation. Whether a swimmer is diving, stroke-swimming or playing water sport such as water polo, the fabric must give just enough flexibility to let them move freely. This is something that nylon is very good at as it is very elastic.
There is some stretch to nylon itself, but it is often combined with fibres like spandex (or elastan) for added stretch. Spandex is extremely supple and makes your swimwear move and fit just like new. This means not only will nylon swimwear be fit to the body’s curves but it will also be tight, secure and not going to restrict movement. Whether you are laying low for a few laps in the pool or running a high-powered race, a nylon suit follows you, supportive but flexible.
Nylon is elastane so it retains its shape, which is important for comfort and performance. Swimming in a race is every split second, and the last thing a swimmer wants is a suit that keeps her body moving or shrinks while swimming. Nylon has an extremely high stretch and shape retention, so it is very comfortable and efficient for athletes.
For the recreational swimmer, nylon is soft and comfortable enough for wear over time. The fabric moulds to the swimmer’s shape, and is second-skin comfortable without compromising support. This pliancy also means the swimmer can freely move in the water and is not bothered by pain when he is doing laps or just chilling at the beach.
2. Quick-Drying Capabilities
What Fast-Drying Means for Swimsuits?
Having a swimsuit that dries quickly is the revolution after you get out of the water. A wet fabric for a swimsuit makes the wearer cold, squinty, and heavy. This is especially so when the swimmer transfers from the water to land where the wet cloth adheres to skin, and may even chafe. So quick-drying materials are a necessity for bathing apparel.
Polyester is fast-drying. It doesn’t soak up as much water as some materials, thanks to its silky-fine fibres and water repellent nature. As you come up from the sea, nylon sips away whatever water it’s taken on, and it dries much faster than cotton or wool. The rapid wicking away of water from the fabric ensures that swimmers don’t lose warmth when they leave the pool, lake or ocean.
Nylon swimwear are quick drying which makes swimming much more comfortable. For instance, if you’re taking the swimsuit from the pool to something else, like sunbathing, running errands, or playing an outdoor sport, then a nylon swimsuit is quick to dry and less damp. That’s quite different from fabrics such as cotton, which don’t dry up, and could make you suck for much longer.
And the quick-drying features of nylon also help keep chafing and irritation at bay. If you wear wet fabric for long enough, you will experience pain, especially if you are active when you swim or play in the water. Since nylon dries quickly, the swimmer is kept comfortable during their work-out or leisure time.
The Contribution of Quick-Drying To Comfort & More?
What nylon swimwear offers you in comfort is more than style, though. You don’t want wet heavy stuff holding you down as you cross from water to land. This is a problem that nylon overcomes by drying much more quickly and wicking moisture more efficiently than most other textiles. For swimmers who like to spend a lot of time in the water, this is an important function for comfort.
Nylon is quick-drying, so there’s no sweaty switching between projects. If you are doing any outdoor activities or water-based exercise classes, then you may have to quickly change from your swimsuit into something else. Nylon also gets dry fast, which means you won’t have to feel wet and uncomfortable when switching clothes — an important feature when time is of the essence in situations such as competition sports or swimming lessons.
Even on the beach, a suit that quickly dries adds to the experience. Nothing’s worse than sitting in wet clothes once you come out of the water. That worry is no longer present in nylon because it’s quick drying, so you stay fresh even after hours in the pool or the sea.
3. Nylon Swimwear vs. Other Fabrics
Nylon vs. Spandex
Spandex (also called elastan) is another swimming fabric. Because spandex is so incredibly stretchy and elastic, it gives swimmers a wonderful freedom of motion. Yet spandex is by itself not so great compared to nylon, and so nylon isn’t a perfect material for swimwear.
When used in conjunction with nylon, spandex makes the fabric stretchier and provides a tight fit that moves with you. These are a nylon and spandex combination that give the ultimate in support and flexibility. Spandex is stretchable and has some movement, but is not chlorine resistant or incredibly durable like nylon. Spandex materials can get loosened and lose their form over time. Yet when nylon is combined with spandex, the material doesn’t stretch and therefore is less saggy and longer lasting.
Moreover, nylon is breathable and more quickly dry than spandex. Spandex may stretch and support, but it won’t necessarily repel water away from your skin like nylon will. With the combination of nylon and spandex, you have a performance fabric that has the best of both worlds — stretch and comfort but also toughness and water resistance.
Nylon vs. Polyester
Polyester is another fabric found in swimwear. Polyester, like nylon, is strong, fade resistant, and dries fast. But there are major differences in these two fabrics, that impact how well they perform in swimming suits.
There are many things that differentiate nylon from polyester such as the ability to breathe. Polyester is breathable, but not as breathable as nylon. The soft and tight nylon fibers will soak up more water so the swimmer isn’t too wet. Polyester is moisture wicking but will keep water more than nylon, so drying times will be longer. Nylon bathing gear therefore is more comfortable to stay dry and lightweight in the water.
Polyester also resists chlorine and is thus perfect for swimmers who frequent chlorinated pools. The nylon is somewhat chlorine resistant, but it will wear out faster over time with pool chemicals. Polyester can last longer, though, especially for swimmers who frequent public swimming pools. But nylon is still extremely strong and withstands wear well if it’s maintained correctly.
A second reason that nylon has a better feel than polyester is comfort. Polyester feels a little stiffer than nylon, which is silkier and more malleable. Because nylon is so pliable, you can get a much more snug and flattering swimsuit that moves with you, which makes it ideal for swimmers who require maximum performance and comfort.
5. Maintenance and Proper Care of Nylon Swimming Wears.
Swimwear goes through the wringer from chlorine and saltwater, to stretching and washing over and over again. There are some tips to help you extend the life of your swimwear when it’s made from fabric, such as nylon. Because nylon is a tough and versatile material, but it can be damaged if you don’t take good care of it. This article will go over how to care for nylon swimwear, what to look out for when washing, and why nylon swimwear keeps performing year after year. Let’s also take a look at nylon’s endurance compared to other swimwear fabrics, such as spandex and polyester, in terms of brittleness and strength.
How To Maintain Nylon Swimming Wear?
Swimming wear gets hit with chlorine and ocean water, sunlight and sweat. These things can cause the fabric to unravel faster, to sag, and become lose their elasticity. Luckily, if you’re a bit more diligent, you can keep your nylon swimming suits in perfect shape for many years. And here are some essential maintenance instructions for preserving the life of your nylon swimwear:
1. Rinse After Every Use
Getting your nylon swimming gear cleaned is the easiest but most essential thing you can do for your nylon swimwear. Pool chlorine, seawater salt, sunscreen or even body lotion all degrade fabrics with time. These chemicals damage the fibres, discolor them, and shorten the lifespan of the fabric.
How to wash your nylon rash guards:
- Freshwater rinse: Rinse your swimsuit right away when you’re done swimming in the pool or ocean. This removes chlorine, saltwater, and sunscreen or body lotion that may have come on to the cloth.
- Don’t use hot water: Hot water makes the fibers of the fabric brittle and stretch out the elastic pieces. Rinse always with cold or lukewarm water.
- Don’t wring: don’t wring your swimsuit to get the water out, press it between your hands to release the water. Wringing stretches the material and stretches the fabric, if not pulling the material out of shape.
If you wash your swimwear immediately after swimming, you will be eliminating the residue of chemicals and salt that will wear away the fabric.
2. Hand Wash, Don’t Machine Wash
You can put your nylon swimsuit in the washing machine, but don’t forget to wash it yourself to avoid fraying. Machine washing, especially with agitators, stretch the fabric, break down elastics, and rub and pill.
Wash your nylon suit by hand:
- Dishwash with a mild detergent: Choose a mild detergent, not loaded with harsh chemicals that could rot the fabric over time. There are even detergents that are made especially for bathing suits and retain elasticity.
- Launder slowly: Fill a tub or sink with cold water and use some detergent. Wash your swimsuit in the detergent for a couple minutes to allow it to rinse.
- Scrub lightly: If needed, scrub lightly where you need more of it like around the straps or the seams. : Scrub the fabric lightly with a soft brush or your fingers.
- Rinse again: Rinse your swimsuit in cold water after cleaning to wash away the detergent residue.
The washing process with hands reduces the risk of ruining the fabric and keeps the stretch and contour of your nylon swimming wear.
3. Dry Properly
Drying should be no less important than washing when you want to treat your nylon swimming wear. How your swimsuit is dried affects how it stays the same shape, stretch and color.
To dry your nylon swimsuit:
Air dry: Never hang your nylon swimsuit without air drying it on a clean dry surface. Hang it not from the straps because this would warp and stretch the fabric. It will remain flat so the straps won’t sag.
Not in the dryer: Never place your swimsuit in a tumble dryer, as the heat breaks down the fibres and the swimsuit will no longer be elastic and strong. And if it is heated too much, nylon will crack or stretch and you will find it less comfortable to wear.
Exposed to the Sun: Dry your swimsuit in a well-ventilated area, but don’t leave it out in the sun for too long. Overexposure to sunlight might fade it and UV rays may damage the fibre structure over time. instead, dry the swimsuit outside in the shade or laying flat to save the color and fabric.
Drying properly stops stretching, fade and wear on your nylon swimming costume, so you will have nice nylon swimming costumes.
4. Avoid Harsh Chemicals
— Chlorine and saltwater destroy nylon, as I mentioned before; but there are also strong chemicals like bleach, tanning creams, and oils that degrade swimwear. Some lotions and sunscreens especially can leave a odour or residue which if left untreated will rip the fabric apart.
To minimize damage from chemicals:
Immediately rinse swimwear from contact with sunscreens and lotions: When using sunscreen, always wash swimwear right after application so that the buildup doesn’t accumulate. That’s especially the case with waterproof/water resistant sunscreens that tend to stick closer to the skin.
Do not use bleach: Bleach is a common cleaning product but it can destroy the soft nylon fibers. If you have to clean a stain, use a mild stain remover that’s not harmful to the fabric, or a vinegar solution to clean stains without breaking them.
Avoid using any noxious chemicals to keep your nylon swimsuit looking clean and healthy.
5. Store Swimwear Properly
An essential part of nylon swimwear care is also proper storage. You don’t want your swimsuit to remain wet, crumpled, for too long, the fabric can wrinkle, become out of shape, and even smell bad.
To store your swimwear:
- Put away in a dry location: Make sure your swimsuit is completely dry before putting it away. Keep damp or wet swimsuits away from direct light and moisture in a closed, dark location as this may invite bacteria and mildew to develop that can give off an odour or break the fabric.
- Don’t fold it in a fist: Keep your swimsuit in a drawer or ventilated mesh bag and don’t try to squeeze it in so it folds into a fist or crumples. Tight folds stretch the fabric and destroy the stretch, especially on the straps.
- Put in a swimsuit bag: If you’re bringing your swimsuit on the go, get a ventilated mesh bag. This keeps your swimwear from getting snarled or broken in the shipping process and is water resistant until you are ready to wear it.
Your swimming wear stays in shape with the right storage and will not be ruined by water or folds for too long.
Durability Over Time
Nylon is very durable and strong, but you still need to care for it so it can perform well. Properly maintained, nylon swimwear lasts season after season without shrinking, darkening, or breaking in.
Why Nylon Swimwear Doesn’t Fade, Change Color, Or Get Waterlogged.
One of nylon’s best qualities is that it does not warp and doe not stretch after repeated use. By washing nylon swimwear with a rinse immediately after wearing, and washing it gently with the aid of a gentle hand and drying it in a cool, dry environment, you can keep the swimsuit fit and soft. Maintenance will prevent sagging or the swimsuit becoming loose during usage (especially when used for recreational and competitive swimming).
The other aspect is color stability. The dyes in nylon bathing suits won’t fade, even if you frequently use chlorine or saltwater. But bad care (no watering after use, drying in direct sunlight) makes colors discolour. You can keep your swimsuit looking as colorful as you want if you follow the care guide.
As a matter of fact, Nylon doesn’t go brittle unless you take special care of it. When you rinse your swimming suit at the end of every swim session, chlorine, salt, or sunscreen don’t corrode the natural water repellent of the fabric. Also, drying your swimsuit in the shade will ensure that the fabric does not lose its water resistance, and it won’t wick away water and feel heavy and tight.
Nylon vs. Other Swimwear Materials
Compared to materials such as spandex or polyester for swimming, nylon is much more comfortable, flexible and resistant to wear. But it can survive based on what kind of care it is given.
Nylon vs Spandex: Spandex (Lycra, elastane) is very elastic but susceptible to chlorine and salt water more than nylon. Spandex is stretchy and loose after a certain amount of time, especially when it isn’t cleaned and taken care of regularly. Nylon on the other hand, stays more curved and doesn’t stretch, which makes it more durable over long-term.
Nylon vs Polyester: Polyester is another very popular fabric in swimwear. Like nylon, it’s chlorine and saltwater resistant, but drys more slowly and can’t be breathed in like nylon. Even the polyester swimming suits can become worse with time, especially if they’re exposed to toxic chemicals or aren’t cleaned properly. The best nylon swimwear will stay shape, colour and work longer than polyester.
Nylon Swimwear with proper care can beat all other fabrics when it comes to long-lasting performance, so if you’re looking for a strong and high-quality swimsuit, you need to consider nylon.
6. The Future of Nylon in the Swimsuits?
The technologies of the swimming costume change with the materials that go into it. While nylon is still a go-to fabric for swimming costumes, there are a few developments coming out that will make it even better.
New Trends in Nylon Fabric Technology For Swimming Gear.
And the future of nylon swimwear will feature technological improvements in fabric technology for both better fit and comfort:
Added Stretch: New innovations in nylon fabric is making it more stretchy and makes swimsuits form to the body, sizing up with a snug comfortable fit. These advances in stretchability might allow nylon bathing suits to stay in place longer without sagging or losing its elasticity.
Advanced Water-Repellent Coatings: Science is working on novel water repellent coatings for nylon swimwear. Such treatments prevent the fabric from absorbing water which reduces drag and buoyancy. The slicker the fabric, the quicker it dries, which is great after a swim.
High Protection Against UV Rays: As consumers become more aware of the risks of direct sunlight, companies are including UV protection in nylon fabrics. Sunscreen in nylon swimsuits protect the skin from the damaging rays and are an important factor for sun-lovers.
The Potential of Eco-friendly Nylon or Recycled Nylon.
The other big trend to watch is the emergence of environmentally-friendly nylons. We’re also seeing more and more recycled nylon — made from leftover plastic bottles or fishing nets — in the swimwear market. This green alternative makes nylon production less environmentally-destructive and gives you the same high-quality and performance of classic nylon fabrics.
