Although we've published numerous posts on fabrics on our blog, we continue to receive messages from you asking for more content on this topic. We can't ignore your requests and are preparing further content – after all, it's worth constantly expanding your knowledge of fabrics. Today, we're taking a closer look at an original and less popular topic – what is elastane and what are its properties? In this post, we'll try to answer this question and introduce you to the characteristics of this fiber.
Elastane – what material is this?
Many of us associate elastane with an inconspicuous addition to the final composition of a material, but we usually do not realize how important its content is for the properties of the clothing.
First, it's worth explaining that, in general, elastane is classified as a synthetic material, specifically a polyurethane fiber (made from rubber containing 85% polyurethane) . Lycra and the lesser-known Dorlastan are also among them. Synthetic fibers are made from ingredients that don't occur naturally. This typically makes them more durable and generally wrinkle-resistant. Elastane is sometimes called Spandex. The history of this material dates back to the 1950s, specifically 1958. Interestingly, it was initially intended for use as rubber in the military industry, but over time, its numerous advantages were recognized, leading to its widespread use in the textile industry.
Why are material mixtures created?
Blending materials is a very common practice in the textile industry. Fabric manufacturers choose to use various admixtures to achieve the desired properties of the material. This method often also results in a more durable material, resistant to various external factors.
Elastane material and its properties
It's worth noting at the outset that the association of elastane as a fabric additive is apt, as it's never found on its own. It's most often combined with cotton, silk, and also with micromodal, as in our invisible ANSIN undershirts.
Why is adding elastane to a product's composition so popular? There are many reasons! A few percent elastane in the composition reduces the material's weight while increasing its durability. Furthermore, its addition provides significant stretch and elasticity, meaning it returns to its previous shape without changing the garment's shape. The advantage of using elastane is the creation of an exceptionally soft and pleasant-to-touch fabric. This is also the case with our Miss Invisible Nude t-shirts. We also use this same material to create best-selling tops, such as the Miss Mellow Light Top.
Where is elastane most often used?
Due to its properties, elastane is often used in the production of sportswear, underwear, and swimwear. Products containing elastane adapt wonderfully to various shapes and are also very comfortable and practical. By using elastane in our invisible undershirts, we've gained a whopping 30% stretch, making them incredibly versatile in size!
Lycra and elastane
When it comes to the properties of elastane and Lycra , these materials are remarkably similar. However, there are several characteristics that distinguish them. First and foremost, Lycra can be found alone or in admixtures, while elastane only appears in admixtures. Lycra is stronger than elastane and is extremely resistant to light, water, and chemicals. Regarding the production process, there are also some differences, as elastane is a knitted thread produced using a special "wet" technology . Lycra, meanwhile, is produced using a "dry" method. It's also worth noting that the name Lycra is a trademark of an American company.
Elastane and its advantages and disadvantages
It's time to address the final issue related to elastane. This material (like any other) has its pros and cons. As mentioned above, elastane's advantages include primarily its elasticity and ability to quickly return to its original shape after stretching. This makes elastane wrinkle-resistant – the higher the elastane content in a garment, the less it will crease. The addition of elastane also increases the material's durability, ensuring that garments made from it will last longer.
A disadvantage of elastane is its low hygroscopicity. However, since its fibers are only present in clothing as a blend, this isn't a real problem. A few percent elastane in a T-shirt or skirt won't negatively impact comfort – on the contrary, it will increase its durability and wrinkle resistance.
How did you like today's rather original post? We hope you learned a lot of useful things about elastane . If you have any specific requests for future articles on materials or perhaps clothing production, let us know in the comments. As always, we're open to your suggestions!
