Elastane is a silky, smooth, shiny material with elastic threads

Elastane’s special combination of properties has made it a fabric that is indispensable in contemporary fashion. Because of its elastic threads, this material is silky and smooth to the touch and has the unique ability to stretch and regain its original shape. It’s the key to many of our favorite clothes’ fit and comfort.

Elastane, in contrast to many other fabrics, has a subtle sheen that gives it an opulent appearance. Its versatility and this quality make it a popular option for everything from everyday clothing to athletic wear. Elastane is essential for a snug but comfortable fit in leggings, swimsuits, and form-fitting dresses.

Elastane is beautiful not only in the way it feels but also in the way it works. Its fabric is made to adapt to your movements, giving you flexibility without sacrificing shape. Because of this, it’s a crucial part of apparel that must fit and stretch to the body while providing equal amounts of style and functionality.

Description and properties

Elastane, sometimes referred to as spandex or lycra, is a synthetic thread made of polyurethane rubber that is thin, elastic, and incredibly strong. It is created in a laboratory. It is most commonly referred to as "elastane" in Europe. The terms spandex and lycra are commonly used in Canada, the United States, and certain other countries.

Since polyurethane elastomer thread is so thin, its pure form is almost never utilized. Thus, fabric made entirely of elastane fibers is just not found in nature. This is merely a synthetic additive that enhances certain properties of other materials. Stretchy threads don’t lessen the natural material’s hygienic qualities or lessen the comfort of clothing made of it when used in small amounts.

Elastane is primarily utilized in mixed fabrics of various kinds in conjunction with other synthetic or natural fibers. Chiffon, silk, knitted materials, wool, linen, cotton, crepe, jacquard, and even elastic suede are a few examples of these. Any fabric can be made elastic and flexible by adding elastane. Such fabric can easily expand in size, either lengthwise, crosswise, or in both directions simultaneously, without losing its shape. Generally speaking, bi-elastic types are the latter.

Elastic fabric clothing hugs the body closely and fits the figure flawlessly without the need for darts or additional adjustments. Elastic knit fabric also drapes nicely and is suitable for almost any type of dressmaking. In the end, the amount of elastic threads a given material contains determines how flexible the final product will be. However, even a small amount of elastane—up to 5%—improves the fabric’s strength, durability, and elasticity.

To summarize everything that has been discussed, elastane is an elastic textile that is highly sought after and has a long lifespan as well as wear resistance. It is employed in the production of numerous kinds of apparel.

Let’s examine this material’s primary features and potential applications in more detail.

A little history

Joseph Shivers, a chemist at the American company DuPont, invented a new synthetic fiber with remarkable elasticity in 1958. Even though the company had previously carried out a number of experiments in an attempt to create a novel fabric. However, it was Joseph Shivers who initially succeeded in creating a strong fiber from a thermoplastic elastomer—a material that turned plastic when heated and precisely stretched. They quickly discovered how to create fabric from elastane fibers, and they used this knowledge to start making stockings, belts, and corsets.

Sportswear manufacturers started to show interest in elastane in the 1960s. And they started making clothing out of it ten years later.

The biggest producers of contemporary elastane, which is registered under numerous trademarks, are dispersed throughout the globe.

The most well-known brands are:

• dorlastan in Japan (Asahi Kasei Corporation);
• lycra, elaspan in the USA (Invista);
• linel in Italy (Fillatice Spa).

Composition and production features

Segmented polyurethane rubbers are the raw materials used to make elastane textile fibers, also known as elastic elastene. The substance consists of pliable sections that are firmly joined to one another. Synthetic fibers have unique strength and elasticity because of this structure, which creates an airy and porous structure.

Spandex is made in the lab by "knitting" the fiber in a few different ways:

1. Formation of threads in a dry or wet way from a solution.
2. Reaction (chemical) formation method.
3. Injection (extrusion) from a molten polymer.

Leaving aside the technical intricacies of these procedures, we can only state that the dry method is the most widely used technique for creating polyurethane fibers. It makes up 80 percent of global production. A 15% chemical and wet method and a 5% melt-based thread formation process are used.

The thin threads that are produced harden. They are used to create bundles, which are dried and wound onto reels after being cleaned.

Elastane is transparent, translucent, and white in color.

When combined with other fibers, elastomeric yarns create a range of textile textures with varying densities. Between 1.1 and 1.3 g/cube. cm is the average.

Pros and cons of elastic matter

Elastane-containing fabrics are distinguished by:

• excellent stretchability – thanks to this quality, any clothes with elastic threads fit well to the body and sit on the figure;
• elasticity and the ability to take the original shape after stretching;
• wear resistance and durability – spandex fibers significantly increase the service life of the fabric, make it durable;
• water resistance – the fabric does not absorb water and dirt and is easy to care for;
• fabric, which contains a synthetic additive in small quantities, does not lose its ability to pass air, in products made from it are as comfortable as from fabric without elastane;
• thinness, softness and lightness – the thinnest synthetic thread does not weigh down the original material at all and drapes perfectly;
• resistance to ultraviolet radiation – does not fade in the sun;
• After washing and drying, the color of the fabric does not change;
• practicality and easy care – fabric with elastane does not deform during use and does not wrinkle;
• density indicator – up to 1.3 g / cu. cm provides the fabric with a "stretch" effect.

Although the material has many advantageous qualities, it also has drawbacks that are primarily related to its synthetic origin, such as the potential for allergies, the inability to absorb moisture, and the buildup of static electricity. Even though the material is naturally breathable, a person wearing such clothing may overheat and perspire excessively in hot weather.

Exposure to either direct sunlight or chlorine can degrade the structure of the elastane-infused fibers in the fabric. Even though contemporary synthetically blended fabrics are highly resilient to sunlight, chlorinated and seawater, and oily, greasy stains, they are still easily cleaned.

Types of elastane fabrics

Lycra fiber

This fabric is elastic and has a high stretchability, which it can maintain even when subjected to strong mechanical loads. Different density indicators are used for white, transparent, and translucent lycra production.

Crepe elastane

High-density substance. The front side is shiny and smooth, while the back is matte. Enhanced strength indicators and drapeability are its distinguishing features.

Meryl

This smooth, elastic material is composed of 10% elastane and 90% polyamide fibers. This fabric is breathable, lightweight, and sturdy. It drapes nicely and doesn’t wrinkle. It does not, however, absorb any moisture.

Classification of elastane by the ability of the fabric to stretch

In addition to variations in density and other physical characteristics, fabrics containing elastane also differ from one another in terms of their degree of stretchability. Above all, remember to use the initial parameters. They can be four-dimensional, where the material stretches simultaneously in all directions, or two-dimensional, where the elastic is either wide or long.

Elastane is a popular fabric for clothing because it is stretchy, versatile, and has a smooth, silky texture. It also has a shiny appearance. Its special elastic threads give clothes a snug, comfortable fit while preserving their shape, making it indispensable for everything from everyday clothing to athletic wear.

Combination with other materials: the most popular fabrics with added elastane

In its pure state, a strong, thin, elastic thread is never utilized. However, when it is present in trace amounts in synthetic or natural fabrics, it enhances their qualities, increasing their elasticity and durability.

Cotton + elastane

No matter how much you iron it, pure cotton fabric wrinkles easily and is very soft. In certain situations, a small amount of elastane threads is added to cotton to give it elasticity, increase elongation, increase strength, and extend its service life. When cotton products with this additive are finished, they look entirely different; they fit well, hardly wrinkle, and do not shrink or stretch after washing. Additionally, they maintain the hypoallergenicity and capacity to "breathe" of natural fabrics.

The material is known as "satin" or "stretch cotton" and is composed of 95% cotton and 5% elastane. Business suits and dresses are frequently made from durable fabric that doesn’t need extra care. For instance, opulent cocktail and evening gowns can be made from exquisite, glossy satin.

A material with comparable properties can be obtained by increasing the percentage of synthetic threads (92% and 8%, respectively) in place of the previous proportions of cotton and elastane. Clothes made of breathable material will continue to feel comfortable and the fabric will remain soft. However, the fabric also gets stronger over time and gains resistance to distortion and changes in its original shape. Sewing underwear and home clothes is a common use for this kind of material.

Viscose + elastane

Breathable viscose fabric’s elasticity and tear strength are increased when it contains 5% elastane and 95% viscose. Such an additive does not cause the fabric to become electrified and keeps its lightness and softness. This fabric is frequently used to make tights and other hosiery.

Linen + elastane

When synthetic fibers are added to linen fabric, the fabric becomes elastic, ceases to wrinkle, and keeps its original appearance for an extended period of time.

Denim + elastane

Polyurethane elastic threads give denim its unique strength and stretchability.

Nylon + elastane

Nylon fabric takes on a unique sheen when combined with elastic threads, making it perfect for making evening gowns.

Cotton + viscose + elastane

The perfect fit and excellent shape retention of finished products are guaranteed by the blend of viscose and cotton fabric with elastane. The fabric is still light and comfortable to wear at the same time.

Knitwear + elastane fibers

Knitwear is an elastic material that is soft, flexible, and well-stretchable. However, knitwear that incorporates elastane fibers is a unique tale. Knitwear becomes much more elastic and even more stretchable when it contains elastane threads, which stretch extremely well before returning to their original size. In addition, knitwear gets more resilient, does a better job of maintaining its color and shape, wrinkles less easily, and requires less maintenance.

In mixed fabrics, elastane works well with silk, wool, polyamide, nylon, and polyester in addition to cotton, viscose, and linen. In a few of them, elastic threads make up only 3-5% of the composition. Their content reaches 15–30% in others. This primarily pertains to the materials used to sew swimsuits and sports uniforms.

Because of its special qualities, elastane is an amazing material that has revolutionized the fashion industry. Its delicate sheen and silky smooth texture make it a popular option for many different types of apparel. Elastane is a material that can be used to create clothing that is both comfortable and stylish, whether it is for sportswear, daily wear, or high fashion items.

The remarkable elasticity of elastane is one of its best qualities. This fabric fits snugly but comfortably because it stretches easily and returns to its original shape. This gives it flexibility and durability, which makes it perfect for clothing that needs to move with the body.

Elastane’s popularity is also attributed to its ability to blend in seamlessly with other fabrics. It improves the feel and functionality of other materials, increasing their adaptability to various uses and styles. Elastane is a fabric that can be used for anything from sportswear to casual attire and still meet the demands of modern living.
