What is Spandex Fabric: Properties, How it’s Made and Where

Spandex fabric has revolutionised athletic wear and fashion, offering unparalleled flexibility, comfort, and durability. Often recognised for its exceptional stretch and recovery properties, spandex is a staple in various applications, from sportswear to casual clothing. This blog post delves into the fascinating world of spandex, exploring its properties, manufacturing process, uses, advantages, and environmental impact. By the end, you’ll have a comprehensive understanding of this versatile fabric and why it remains a top choice among designers, manufacturers, and athletic wear enthusiasts. So, let’s get started!

Properties of Spandex Fabric

Spandex fabric, also known as elastane or Lycra, is a synthetic polymer with exceptional elasticity. It can stretch up to 500% of its original length and return to its original shape without losing integrity. This unique property makes spandex an ideal choice for body-hugging garments, such as leggings, swimsuits, and athletic wear.

Apart from being incredibly stretchable, spandex fabric also offers excellent resistance to abrasion and chemicals. It’s highly durable, lightweight, and breathable, making it suitable for various weather conditions. Additionally, spandex is resistant to heat and humidity and dries quickly, making it the go-to choice for athletes.

How Spandex Fabric is Made

Spandex fabric is made from petrochemical products, primarily polyurethane. The polymer undergoes a complex process of spinning and chemical treatments to create long-chain molecules with high elasticity. These fibres are then spun into yarns and woven or knitted into fabrics.

The manufacturing process of spandex involves several stages, including extrusion, coagulation, washing, dry-spinning, wet-spinning, drawing, crimping, and heat treatment. Each stage plays a crucial role in achieving the desired stretch and recovery properties of the final product.

What Different Types of Spandex Fabric Are There?

Spandex isn’t just a one-type-fits-all material. Various types of spandex fabrics cater to specific needs and applications. Here are some common types:

• Single-Covered Spandex: This type features a single yarn wrapped around the spandex core, often used in socks and hosiery.
• Double-Covered Spandex: Here, two yarns are wrapped around the spandex core, providing additional strength and durability, ideal for more robust applications like athletic wear.
• Air-Covered Spandex: In this type, air jets are used to intermingle the spandex fibre with other fibres, creating a soft and stretchy fabric often used in intimate apparel and seamless garments.
• Bare Spandex: This refers to spandex yarn without any covering, typically used in knitting and weaving processes.

Each type offers unique properties that make spandex suitable for a wide range of uses.

What are the Properties of Spandex?

Spandex boasts a range of impressive properties that make it a sought-after fabric in the fashion and athletic industries:

• Elasticity: Spandex can stretch up to 500% of its original length, making it incredibly flexible.
• Strength: Despite its elasticity, spandex is durable and resistant to wear and tear.
• Lightweight: Spandex is lightweight, adding minimal bulk to garments.
• Moisture-Wicking: This moisture-wicking technology ensures you stay dry and comfortable, effectively drawing sweat away from the body. Perfect for active individuals seeking comfort and dryness during their workouts..
• Shape Retention: Spandex quickly returns to its original shape after stretching, ensuring a snug fit.
• Softness: The fabric is soft against the skin, enhancing comfort.
• Resistant to Body Oils and Sweat: Spandex maintains its properties even when exposed to body oils and sweat.

These properties make spandex an ideal choice for garments that require a close, comfortable fit combined with durability.

What is Spandex Commonly Used For?

Due to its unique properties, spandex finds applications in a variety of clothing and textile products:

• Athletic Wear: From yoga pants to cycling jerseys, spandex is a favourite in sportswear for its flexibility and moisture-wicking capabilities.
• Swimwear: Its ability to stretch and return to shape makes spandex ideal for swimwear.
• Intimate Apparel: Spandex is often used in bras, underwear, and shapewear for a comfortable, snug fit.
• Casual Clothing: Jeans, leggings, and tops often incorporate spandex for added stretch and comfort.
• Medical Garments: Compression garments, supports, and bandages benefit from the elasticity and strength of spandex.
• Costumes: Spandex is popular in dancewear and costumes due to its flexibility and form-fitting nature.

Its versatility ensures spandex remains a critical component in various clothing lines.

What are the Advantages of Spandex?

Spandex offers numerous advantages that make it a preferred fabric in many industries:

• Comfort: Its elasticity provides a comfortable fit that moves with the body.
• Versatility: Spandex blends well with other fibres, enhancing the properties of the final fabric.
• Durability: Items made with spandex maintain their shape and appearance over time.
• Easy Care: Spandex garments are generally easy to care for and maintain.
• Fit: It offers a superior fit compared to non-stretch fabrics, enhancing the wearer’s appearance.
• Performance: For athletes, spandex provides the necessary support and mobility during activities.

These advantages contribute to spandex’s widespread use and popularity.

What is the Quality of Spandex?

The quality of spandex can vary based on several factors:

• Fibre Composition: High-quality spandex fibres ensure better performance and longevity.
• Manufacturing Process: Advanced manufacturing techniques result in finer and more consistent spandex fibres.
• Blending: The way spandex is blended with other fibres can affect the final fabric’s quality.
• Brand Reputation: Reputable brands often produce higher-quality spandex fabrics.

It’s essential to consider these factors when choosing spandex products to ensure you get the best quality for your needs.

How is Spandex Made?

Spandex fibres are made from polyurethane, a synthetic polymer with versatile properties. The manufacturing process involves several steps:

1. Prepolymerization: The raw materials, including polyols and diisocyanates, undergo chemical reactions to produce a prepolymer.
2. Chain Extension: A catalyst is added to the prepolymer to encourage further reaction, forming long chains of repeating units.
3. Spin-Drawing: The resulting liquid solution is extruded through spinnerets into warm air chambers, stretching the fibres and orienting their molecules.
4. Stabilization: The fibres are then heat-set and washed before being wound into spools, ready for use.

Spandex production requires specialized equipment and expertise, contributing to its relatively high cost compared to other fabrics.

How Does Spandex Fabric Impact the Environment?

While spandex offers numerous benefits, its environmental impact is a concern:

• Synthetic Nature: Spandex is a synthetic fibre, primarily derived from petroleum, which is not a renewable resource.
• Non-Biodegradable: Spandex is not biodegradable, contributing to long-term waste.
• Production Process: The production of spandex involves chemicals and solvents that can be harmful to the environment if not managed properly.
• Landfill Waste: Spandex garments that end up in landfills will take a long time to decompose, adding to the already growing waste problem.

To reduce its impact on the environment, consider purchasing spandex from brands that prioritize sustainability and proper waste management practices. Also, try to extend the life of your spandex garments by properly caring for them and donating or recycling when no longer needed.

The Future of Spandex

As technology advances, so does the production and use of spandex.

Developments in recycling methods and sustainable production techniques offer hope for a more environmentally friendly future.

Additionally, new applications are emerging for spandex, such as in medical textiles and 3D printing, expanding its potential uses beyond clothing.

With its unique properties and versatility, it’s safe to say that spandex will continue to be an essential fabric in the fashion and textile industries for years to come.
