Elastic and elastic spandex – what is it made of and why is this material so popular

Because of its exceptional stretch and flexibility, spandex—also referred to as elastane—has become a mainstay in contemporary apparel. This material, which provides unmatched comfort and style, has completely changed the way fabrics move and fit, whether it is used in sportswear, swimwear, or regular clothing.

However, what precisely is spandex composed of, and why is it so well-liked? In contrast to conventional fibers like cotton or wool, spandex is a synthetic material made by a multi-step process involving polymers and chemicals. As a result, the fiber retains its shape even after stretching up to five times its initial length.

The distinctive blend of stretch, durability, and versatility that makes spandex so popular. Its ability to mix and match with various materials makes it an essential component of apparel that fits well and doesn’t restrict movement. Stretch has earned a spot in countless wardrobes all over the world as a go-to fabric for everything from fitness gear to wardrobe essentials.

What is spandex

Actually, there’s no particular fabric known as "spandex." Any substance that has at least 2% of spandex—elastic, smooth, and shiny polyurethane fibers—can be referred to as this. That is to say, it is implied that the term "fabric" is merely a general term for materials with varying compositions.

The literal translation of the word "spandex" from the English verb "expand" is "to stretch."

Additionally, producers of polyurethane material from various nations have patented their trade names. Although they have different sounds, they have the same meaning as the popular term "spandex" in the USA and Canada. This material is more commonly referred to as elastane in Europe, vorin in Italy, and neolan in Japan.

When spandex, lycra, and elastan are included in the composition of a fabric or object, it always means that the material has the ability to stretch precisely and quickly return to its original size.

Seldom is fabric made and used, as it only consists of synthetic polyurethane fibers derived from polyurethane rubbers. However, elastic, wear-resistant spandex threads are frequently used as an additive to other fibers, particularly to those that do not stretch well. They are added to mixed fabrics made of viscose, linen, silk, nylon, or polyester, as well as knitted cotton or woolen fabric.

The original material’s qualities are greatly enhanced by even a small amount of synthetic fibers, outperforming even natural counterparts in certain areas. Spandex-infused fabric stretches nicely and returns to its original shape and size fast. In addition to giving the fabric elasticity, this addition keeps the material from stretching.

Numerous applications call for the material’s qualities. even in the light industrial sector. It’s used to make headgear, accessories, sports and casual apparel, weight-loss products, stockings, socks, and tights.

History of spandex

1959 marked the start of the spandex era. Stretchable fiber was created around this time by American chemist Joseph Shivers of the DuPont company. This came about as a result of intensive scientific research aimed at producing a more affordable, flexible kind of rubber to satisfy the army’s technological and equipment requirements.

This is how the greatest rubber substitute—which still exists today—appears. Other textiles started to get elastic and stretchable when light, thin, well-stretched, and elastic fibers were added to them. A stretchy substance, marketed under the Lycra brand, hit the shelves. Following the development of Lycra-based synthetic tights and stockings, word of the new material rapidly expanded throughout the globe.

The ability to fit and stretch well on the body was used in the creation of sportswear. There were sports leggings. In the 1980s, knitted pants became popular, and many people learned about them along with the rise of aerobics. Sportswear quickly made a name shift to "leggings" (derived from the English word "leg" – "leg") and started to show up on fashion catwalks.

These days, spandex is actively used to make lingerie, accessories, swimsuits, corsets, and sports and leisure wear for both men and women.

Elastic spandex, or just spandex, is a multipurpose fabric mainly composed of synthetic fibers such as polyurethane. Its remarkable stretchability, which enables it to enlarge up to five times its initial length while maintaining its original shape, is its primary characteristic. Due to this special quality, spandex is very popular in sportswear, activewear, and fashion, industries where durability, comfort, and flexibility are crucial. Because of its capacity to blend in with other materials, give an extremely tight fit, and endure frequent washings, spandex has become the material of choice for apparel that must flex with the body.

Fabric composition

In its purest form, the synthetic material spandex—which is made of polyurethane fibers—resembles rubber and bears little resemblance to conventional textile fabric. Its composition consists of up to 85% polyurethane with additional components such as nylon and acetate that are polymer compounds.

The initial raw material is chemically processed to create elastic polyurethane threads. Artificial fiber appears as elastic, long threads at the polymer’s exit after it has melted and solidified. After more processing, they are delivered to a weaving machine.

The threads are white in color, soft, thin, elastic, and long-lasting when used to create fabrics. They are treated with acid or dyes are dispersed to make them look more appealing.

It is rare to find pure spandex fabric for production. However, synthetic threads are frequently found in a variety of fabrics as elastic additives. Furthermore, they exhibit different manifestations of the capacity to stretch like an elastic band and then return to their initial state. It depends on the material’s intended use by the consumer as well as the raw materials—natural or synthetic—that are incorporated into it.

Spandex in other fabrics

Many textiles acquire a soft, delectably pleasant texture when smooth, light, and shiny synthetic threads are added. This broadens the range of applications for them. The shape and springiness of the material are enhanced by even a small percentage (2%) of polyurethane in the composition. The quantity of synthetic fibers affects its elasticity.

Streich-Kotton is cotton fabric with a trace amount of synthetics. The qualities of natural fabrics are not compromised by polyurethane additives. They continue to be pliable, sweating, and soft. Simultaneously, items maintain their aesthetic appeal even after repeated washings, are cozy to wear, resist wrinkles, and the fabric does not shrink.

The combination of satin and elastan gives textiles their strength, softness, and airiness.

Elastic viscose is synthetic canvas that contains spandex threads, but not more than 5% of the total. The soft, light fabric is pleasant to the touch and is used to sew home and clothing items. High density and strength are characteristics of this type of matter.

Elastan is a warm fabric that is used in frost and non-cold products. Woolen knitwear is made more elastic and protected from stretching by the presence of spandex threads.

Elastic, soft, and warming material made of acrylic knitwear with spandex threads. Sweaters, cardigans, and jumpers can be sewn with it.

Is the mixture of spandex and polyester pure synthetic? Despite being comfortable to wear and having good air passage, the material degrades in the presence of sunlight. Special handling is necessary for fabric with a stretch effect, which is composed of 97% polyester and 3% spandex. and apprehensive of extreme heat.

This fabric is used to create stage and sports suits, jackets, raincoats, hosiery, and compression and corrective underwear. Most often, wetsuits and workwear are made of super-elastic material with a 20–30% spandex content.

The fabric’s ability to maintain its shape and not wrinkle or deform is due to the spandex, polyester, and acetate combination.

The combination of nylon and spandex gives the fabric strength and a high density. This kind of material lasts a long time looking good.

The majority of the time, lining spandex is made entirely of synthetic fibers, such as PE or acetate. This fabric has three main qualities: smoothness, elasticity, and shine.

Elastic, plastic Lycra with spandex threads in the base. fits the body perfectly.

Diving is a contemporary knitwear style composed of synthetic and man-made fibers. It is typically composed of polyester or viscose, with up to 5% of spandex (also known as elastane) required. It might have as little as 10% or so cotton in it.

Soft, elastic fabric is used to make leggings, regular and corrective underwear, bodysuits, swimsuits, and other clothing items in addition to sportswear.

Yarn enhanced with spandex. Knitters are aware of the convenience of working with elastane-containing knitting threads. The yarn becomes somewhat sliding, more elastic, and smoother. Knitted items composed of it maintain their shape effectively. Spandex-infused yarn is less expensive than natural yarn.

Biospanex. Elastane, also known as spandex, is derived from petroleum-based products’ polymers. Hyosung, a South Korean company, attempted to create these incredibly useful textiles by utilizing biological elements taken from corn. Based on biology, a novel material with enhanced elasticity was created: biospandex. This fabric can be used to create home textile items as well as athletic, casual, and medical garments.

Polyester or spandex – which is better?

Buyers often compare spandex and polyester in an attempt to better understand the characteristics of different synthetic materials. These two materials are synthetic. Every one has benefits and drawbacks.

Polyester comes in a wide range of textures and colors and is a pleasant, silky fabric to the touch. Its low cost and high wear resistance define it. The density of 100% polyester is high. It is, however, extremely electrified at the same time.

Spandex is prized for its adaptability, resilience, and elasticity.

The main properties and characteristics of spandex

The primary benefit of synthetic spandex lies in its elasticity, which allows it to promptly regain its original shape even after experiencing significant mechanical force.

The fibers have 500–700% stretchability, meaning they can stretch five to eight times their initial length. Stretch in blended fabrics is reduced to 180–2000%. However, this also serves as a strong indicator and assurance that the textile fabric and goods manufactured with it won’t sag or distort.

Most frequently, two-dimensional materials that stretch in both width and length are created. Additionally, there is a four-dimensional fabric that stretches uniformly in all directions.

Despite being lightweight, spandex has a high density of 200 g per square meter.

• Wear resistance and practicality.
• Durability and reliability.
• Moisture resistance – does not absorb sweat and moisture. This quality is especially appreciated in sportswear.
• Softness and comfort – smooth, silky fabric with a slight sheen is pleasant to the body.
• Wrinkle resistance – the fabric does not crease or wrinkle.
• The material is well dyed, holds color, and can be decorated.
• With proper care and use, spandex does not shrink or fade.
• Resistance to dirt – synthetic threads repel dirt from the surface, preventing it from penetrating into the fiber. Stains are easy to wash out, things dry quickly.

However, in theory, there is no perfect material. This fabric also has some disadvantages. Additionally, they are mostly found in synthetic materials. However, combining synthetics with other fibers can reduce or eliminate some things entirely. Textiles made of cotton, wool, and linen that have been treated with elastane, for instance, have the natural properties of breathability, hygroscopicity, softness, comfort, and heat-saving ability.

• poor thermoregulation;
• destruction when exposed to high temperatures when washing, ironing;
• elasticity can become a problem when cutting fabric and sewing;
• accumulation of static electricity;
• with a high content of elastane in the composition, snags can form on the fabric, and pellets can appear from frequent washings;
• spandex absorbs odors well;
• The chemical composition of the material does not guarantee the absence of allergic reactions.

Synthetic fabric also has the drawback of being sensitive to light. However, it has already been essentially eliminated in new types of fabric with the addition of light-resistant to ultraviolet threads. Swimsuits and beachwear are made from this type of fabric.

Where spandex is used

Elastane threads are added to fabrics to enhance their qualities, and these fabrics find widespread application in the furniture, chemical, textile, and medical fields. Sewing clothes remains the primary application area, though.

It’s impressive even to make a simple list of the categories of items made of this type of fabric. These are the sports and leisure wear items that fit the figure and don’t impede movement: blouses, dresses, pants, and jeans. Stage attire includes dresses and costumes for gymnasts, synchronized swimmers, figure skaters, and circus acts.

Extreme sports enthusiasts, such as snowboarders and skiers, value spandex suits’ high strength, deformation resistance, and water resistance.

Undergarments. Elastane is present in trace amounts in common models made of cotton. Synthetics are widely used in fabrics for anti-cellulite, corrective, shaping, and compression undergarments.

Swimsuits, thermal underwear, tights, stockings, and socks all have a stretch effect that fits the body flawlessly and has a recognizable shine and smooth surface.

Another use for spandex-containing threads is in handicrafts. These are all different types of ornamental ribbons and laces that are used to make bracelets and other jewelry. Yarn with polyurethane fibers is used to create elastic, resilient products.

Features of sewing spandex items

When purchasing fabric for hand sewing, keep in mind that it is a difficult material to work with and requires a certain level of expertise:

• when sewing, it is advisable to use a needle for knitwear or for stretch fabric;
• Marking should be applied to the fabric with a piece of soap or a special pencil – pins may leave marks on the fabric;
• Before starting the main work, it is better to practice on working out the seam on an unnecessary piece of fabric;
• you can sew the parts with a zigzag stitch, slightly stretching the fabric, or with an elastic thread.

By the way, a lot of businesses combine synthetic and natural fibers with spandex to create materials. Customers frequently rank Akshar Enterprise (India), A&K Fabrics and Textile (Bangladesh), Al Haram Trader (Pakistan), Antex+Case GmbH (Germany), and fabric producers from China, Turkey, and Russia among the top producers of textiles.

Because of its amazing stretch and durability, spandex has become a necessary component in the fashion industry. The versatility it offers makes it ideal for use in sportswear, regular clothing, and specialty apparel. Designers are able to create form-fitting pieces that flow naturally with the body thanks to this special fabric.

Spandex is combined with other materials to improve garment comfort and durability without adding weight. Because of its adaptability, spandex has become a popular material for everything from swimsuits to yoga pants.

Knowing the composition and advantages of spandex makes sense when considering why it’s still a favorite in a variety of industries. We anticipate seeing even more creative applications for this elastic material in the future as technology develops.
