Hey there! As a lining and interlining supplier, I often get asked if these materials can be used in swimwear. It's a valid question, considering swimwear has its own unique set of requirements. In this blog post, I'll dive into whether lining and interlining have a place in swimwear and explore the potential benefits and considerations.
First off, let's understand what lining and interlining are. Lining is a fabric layer that's placed on the inside of a garment to give it a finished look, add comfort, and sometimes provide extra protection. Interlining, on the other hand, is a layer that's added between the outer fabric and the lining (or just the outer fabric) to give the garment more body, shape, and stability.
Now, when it comes to swimwear, the traditional mindset has been that it's best to keep things simple. Swimsuits are supposed to be lightweight, quick - drying, and flexible to allow for easy movement in the water. But that doesn't mean lining and interlining can't have a role.
Potential Benefits of Using Lining and Interlining in Swimwear
1. Added Modesty and Comfort
Some people might feel more comfortable with a bit of extra coverage. A lining can provide that additional layer, especially for swimsuits with thinner or more sheer outer fabrics. It can prevent any embarrassing see - through situations and make the wearer feel more at ease. For example, if you're wearing a white swimsuit, a lining can keep things discreet when the fabric gets wet.
2. Shape and Support
Interlining can help give swimwear more structure. Bikinis and one - piece swimsuits can sometimes lose their shape over time, especially with frequent use and stretching. An interlining, like the Thermo Bond Woven Interlining, can add some stiffness and support, helping the swimsuit hold its form better. This is particularly useful for swimsuits with a lot of detail or a specific design that needs to be maintained.
3. Protection
The sun's rays can be harsh, and chlorine in swimming pools can damage fabrics. A lining can act as a barrier, protecting the outer fabric of the swimsuit from fading and degradation. It can also provide a bit of extra protection for the skin, reducing the direct contact between the skin and the chemicals in the pool.
Considerations When Using Lining and Interlining in Swimwear
1. Weight and Dragging
One of the biggest concerns with adding lining and interlining to swimwear is the extra weight. In the water, any additional weight can slow you down and make movement more difficult. You don't want your swimsuit to feel like an anchor. So, if you're going to use lining or interlining, it's crucial to choose lightweight materials. The Microdot Fusible Woven Fusing Interlining is a great option as it's relatively light and won't add too much bulk.
2. Drying Time
Lining and interlining can increase the drying time of the swimsuit. Since swimwear is often used in and out of the water, it's important that it dries quickly to avoid discomfort. Make sure to select materials that are quick - drying. Some linings are made from moisture - wicking fabrics that can help with this.
3. Compatibility with Outer Fabrics
The lining and interlining need to be compatible with the outer fabric of the swimsuit. They should have similar stretch properties and be able to withstand the same conditions. For example, if the outer fabric is a stretchy spandex blend, the lining and interlining should also be able to stretch without bunching or pulling.
Types of Lining and Interlining Suitable for Swimwear
1. Bonded Blackout Interlining
The Bonded Blackout Interlining can be a great choice for swimwear. It provides a bit of extra opacity, which is useful for swimsuits that need to hide any imperfections or prevent see - through. It's also relatively lightweight and can be bonded to the outer fabric easily.
2. Lightweight Woven Interlinings
There are many lightweight woven interlinings available that are suitable for swimwear. These interlinings can add just the right amount of support and shape without adding too much weight. They're also flexible enough to move with the body in the water.
Real - World Applications
Let's take a look at some real - world examples of how lining and interlining are being used in swimwear.
High - End Swimsuits
In the high - end swimwear market, designers are often looking for ways to differentiate their products. Adding a lining or interlining can be a way to add value and quality. For example, a designer might use a soft, silk - like lining in a luxury one - piece swimsuit to give it a more luxurious feel.
Performance Swimwear
Even in performance swimwear, where weight and speed are crucial, there are ways to use lining and interlining. Some performance swimsuits use a thin, lightweight interlining in strategic areas, such as the bust or waist, to provide support without sacrificing too much speed.


Conclusion
So, can lining and interlining be used in swimwear? The answer is yes, but with some careful consideration. There are definitely benefits to using these materials, such as added modesty, support, and protection. However, it's important to choose the right materials to avoid issues like extra weight and slow drying time.
