How is spandex made?
Spandex production is a complex, multi-step process that involves mixing macro glycols and di-isocyanate monomers together, heating them up, and then shaping them into thin fibers.
These fibers are then treated with some seriously strong chemicals to give spandex that unique stretchiness and strength it is known for.
While the end product itself has long been considered chemically inert, and therefore safe, the manufacturing of spandex involves several extremely toxic chemicals that raise health and safety concerns for both manufacturers and consumers.
Chemical Components of Concern
Polyurethane: As the primary component of spandex, polyurethane itself is not classified as a carcinogen, but isocyanates used to make polyurethane are considered potential human carcinogens. Repeated exposure to isocyanates has been linked to liver and kidney disease, as well as respiratory issues such as occupational asthma. Damaging effects on the brain and central nervous system (like headaches) have been reported.
Toluene Diisocyanates (TDI): Used in the production of polyurethane, TDI is a potent respiratory toxin. Exposure can cause asthma, lung irritation, and respiratory sensitivities.
Dimethylformamide (DMF): This solvent, used to dilute the polymer solution, poses health risks to workers if not handled properly. Exposure to DMF can cause liver damage and other health issues.
Formaldehyde: Often used in the processing of spandex, formaldehyde is also a known carcinogen and can cause skin irritation and allergic reactions.
The use of these chemicals raises concerns not only for the health of workers involved in spandex production but also for the potential for toxic chemical residues to remain on the final fabric.
Health Risks & Safety Concerns Associated With Wearing Spandex
Skin-Related Issues
Contact Dermatitis & Allergic Reactions: The chemical residues from spandex manufacturing, such as dyes and formaldehyde, can linger on the fabric and cause skin irritation or even allergic reactions. If you’ve ever experienced redness, itching, or a rash after wearing spandex, you might be dealing with contact dermatitis.
Increased Risk of Fungal & Bacterial Infections: Spandex’s tight-fitting nature and poor breathability create a warm, moist environment that’s a breeding ground for fungi and bacteria. This can lead to infections like ringworm, folliculitis, and impetigo.
Higher Likelihood of Yeast Infections: Ladies, listen up – wearing spandex underwear or leggings for extended periods can increase your risk of yeast infections. The moisture-trapping nature of spandex creates an ideal environment for Candida albicans, the fungus responsible for those pesky infections.
Moisture-Related Health Issues
Poor Breathability: Spandex is notorious for its lack of breathability. When you work out in spandex, sweat, and moisture get trapped against your skin, creating a damp, uncomfortable environment that’s perfect for bacterial growth.
Increased Risk of Skin Rashes: All that trapped moisture can lead to skin rashes, especially in areas where the fabric rubs against your skin, like your thighs or underarms. If you’re prone to eczema or have sensitive skin, spandex might exacerbate these issues.
Respiratory Issues
Potential Asthma Reactions & Lung Irritation: Prolonged exposure to toluene diisocyanates (TDI), used in spandex manufacturing, can cause asthma, lung irritation, and other respiratory problems. While this primarily affects workers, research remains inconclusive about the long-term respiratory effects of wearing spandex clothing.
Who should avoid wearing spandex?
Individuals with Easily Irritated Skin
If you have sensitive skin that’s prone to irritation, you might want to steer clear of spandex. Spandex’s synthetic fibers can rub against your skin, causing redness, itching, and discomfort. The close-fitting nature of spandex garments only amplifies this effect, as the fabric is constantly in contact with your skin.
The chemicals used in spandex production can also linger on the fabric and cause skin reactions. If you have sensitive skin, you might be more susceptible to these reactions.
Those with Pre-Existing Medical Conditions
If you have eczema, psoriasis, or other skin conditions, wearing spandex can exacerbate your symptoms. The tight fit and poor breathability can trap sweat and irritants against your skin, leading to flare-ups and discomfort.
For those with chemical sensitivities or allergies, the residual chemicals in spandex can be a major trigger. If you have a history of contact dermatitis or are prone to reactions from synthetic materials, it’s best to avoid spandex altogether.
While spandex itself doesn’t contain latex, some people with latex allergies may experience cross-reactivity. Additionally, if you have respiratory issues like asthma, the chemicals used in spandex production could potentially aggravate your symptoms.
Fitness Enthusiasts
When you sweat, your skin becomes more permeable, allowing toxic chemicals to be absorbed more easily.
If you’re engaging in activities that make you sweat heavily, like intense workouts or hot yoga, you might want to opt for a more breathable, moisture-wicking fabric.
The same goes if you live in a humid area. The fabric’s lack of breathability can make you feel sticky and sweaty, leading to skin irritation and discomfort.
Babies, Children, and Pregnant Women
When it comes to the most vulnerable among us, extra caution should be taken when it comes to spandex. Babies’ skin is about 30% thinner than adults‘, making them more susceptible to chemical absorption and irritation.
The spandex content in baby clothes should be limited to 5% or less if used at all. Children with sensitive skin or allergies shouldn’t wear clothing with spandex at all.
While spandex can provide much-needed support during pregnancy tight-fitting spandex garments can restrict blood flow and make temperature regulation more challenging.
Pregnant women may also experience increased sensitivity to chemicals in synthetic fabrics so opting for organic maternity clothes is best.
Environmental Impact of Spandex Fabric
The Toxic Toll Of Chemical Use
All of the toxic chemicals it takes to create spandex are just as bad for the environment as they are for our health.
Spandex manufacturing relies on toxic solvents that ultimately are released as wastewater that can contaminate our water sources, harming aquatic life and potentially affecting our drinking water.
Additionally, synthetic dyes used to treat spandex garments can pollute waterways, harm marine ecosystems, and enter the food chain.
High Energy Consumption
Spandex production is an energy-intensive process that often relies on non-renewable sources like fossil fuels that contribute to the fabric’s significant environmental footprint.
The carbon footprint of spandex is estimated to be around 17 kg CO2-eq per kilogram of fabric produced, which is higher than most other synthetic materials like polyester and acrylic.
Resource Depletion
The primary raw material for spandex is petroleum, a non-renewable resource. As demand for spandex grows, so does the strain on this finite resource.
The extraction of petroleum and other raw materials can lead to habitat degradation and loss of biodiversity in affected areas.
Non-Biodegradable
And unfortunately, the environmental impact of spandex doesn’t end when the garment is produced. In fact, it’s just the beginning.
Spandex is a synthetic material that doesn’t biodegrade. This means that when spandex garments end up in landfills, they can stick around for centuries, contributing to the growing problem of textile waste.
Recycling spandex is also challenging, as the material is often blended with other fibers. Even small amounts of spandex can complicate the recycling process, making it difficult to recover and reuse the material.
Microplastic Shedding
When spandex garments are washed, they shed tiny synthetic fibers known as microplastics. These microplastics which can contain PFAS end up in waterways and can be ingested by marine life, potentially causing harm to both animals and humans who consume them.
What are better fabric alternatives to spandex?
Best Alternatives
Organic Cotton: Unlike spandex, organic cotton allows your skin to breathe and effectively absorbs moisture, keeping you cool and comfortable throughout the day. It’s also naturally soft and non-irritating since it’s free of chemical pesticides and herbicides, making it an excellent choice if you have sensitive skin or if you are prone to allergic reactions.
Organic Hemp: Hemp is often overlooked as a fabric choice, but its incredible properties make it a sustainable alternative to spandex. Organic hemp is known for its strength, it’s actually five times stronger than cotton. This means your hemp garments will last longer, reducing the need for frequent replacements. Hemp is also naturally resistant to bacteria, mold, and mildew- great for working out in.
Natural Bamboo (Not Bamboo Viscose): When it comes to bamboo fabric, it’s essential to distinguish between mechanically processed bamboo and chemically processed bamboo viscose. Natural bamboo is produced using a mechanical process that doesn’t involve harsh chemicals. Due to the labor-intensive process of mechanical processing, natural bamboo fabric is less widely available and often comes with a higher price tag compared to bamboo viscose.
Good Alternatives
At SKL we always recommend 100% certified organic natural fibers as the safest and healthiest option.
But we understand a little stretch can go a long way, especially when you’re looking for a comparable replacement for spandex.
If you are looking for fabric that provides decent stretch, TENCEL fabrics are your next best choice.
TENCEL Lyocell: TENCEL Lyocell is still a synthetic fabric, but it’s often considered a healthier and more eco-friendly alternative. TENCEL Lyocell is derived from sustainably sourced wood pulp, often from eucalyptus trees grown in responsibly managed forests. Compared to traditional viscose production, TENCEL Lyocell uses a more environmentally friendly solvent and requires less chemical processing.
TENCEL Modal: While similar to Lyocell, TENCEL Modal is made from beech trees, which are sustainably harvested from responsibly managed forests. TENCEL Modal is extremely soft and feels luxurious against the skin and is perfect for intimate apparel and loungewear. It efficiently absorbs moisture and quickly releases it, keeping your skin dry and preventing bacterial growth.
What To Look For When Choosing Better Alternatives To Spandex
Check Fiber Content: Always check the fiber content of the garment. Look for high percentages of organic cotton, hemp, TENCEL Lyocell, or TENCEL Modal. If a product contains spandex, consider the overall percentage and whether it’s essential for the garment’s function.
Look for Certification Standards: Keep an eye out for certifications like GOTS (Global Organic Textile Standard) for organic cotton or the OEKO-TEX Standard 100, which ensures the fabric is free from harmful substances. These certifications can help you identify more sustainable and health-conscious options.
Avoid Misleading “Bamboo” Labels: Be wary of products simply labeled as “bamboo.” Many of these are actually bamboo viscose, which involves chemical processing. Look for terms like “bamboo linen” or “mechanically processed bamboo” to ensure you’re getting the eco-friendly option.
Verify Processing Methods: For fabrics like TENCEL Lyocell and TENCEL Modal, check the brand’s website or contact them directly to verify their production methods. Ensure they use closed-loop processes and more environmentally friendly solvents.
What should I keep in mind when wearing clothing with spandex?
If you do choose to wear clothing containing spandex, proper care is essential to minimize potential health risks. Here’s what you need to know:
Clean New Items Before First Wear: Always wash new spandex garments in a gentle detergent before wearing them for the first time. This helps remove any residual chemicals from the manufacturing process that could irritate your skin.
Use Gentle, Fragrance-Free Detergents: Opt for mild, fragrance-free detergents when washing your spandex clothing. Harsh chemicals and fragrances can linger on the fabric and cause skin irritation, especially for those with sensitive skin.
Avoid Hot Water Washing: Wash your spandex garments in cold or lukewarm water. Hot water can break down the elastic fibers, reducing the garment’s lifespan and potentially releasing more chemicals.
Wearing Guidelines
Limit Duration of Wear: Try not to wear spandex garments for extended periods. The longer you wear them, the more likely you are to experience skin irritation or discomfort. If you must wear spandex for long hours, consider garments with a lower spandex content or take breaks when possible.
Avoid Wearing in High-Humidity Conditions: Spandex doesn’t breathe well, which can be particularly problematic in humid environments. The trapped moisture can lead to skin irritation, chafing, and even bacterial or fungal growth. If you live in a humid climate, consider alternative fabrics or save your spandex for cooler, drier days.
Change Immediately After Sweating: If you’ve been sweating heavily in your spandex clothing, change out of them as soon as possible. The combination of sweat and tight-fitting fabric can create a breeding ground for bacteria, increasing the risk of skin infections.
Choose Appropriate Activities for Spandex Wear: While spandex is often associated with activewear, it’s not always the best choice for every workout. High-intensity activities that involve a lot of sweating may be better suited for more breathable, moisture-wicking fabrics. Save your spandex for lower-impact activities or those that require a full range of motion, like yoga or Pilates.
Is it safe to sleep in spandex clothing?
Sleeping in spandex clothing isn’t recommended. Spandex’s poor breathability creates a warm, moist environment that becomes a breeding ground for fungi and bacteria, which is especially problematic during extended wear like sleeping.
The fabric traps moisture against your skin, increasing the risk of various infections, skin rashes, and contact dermatitis. Chemical residues in the material can also cause allergic reactions.
You’re better off choosing breathable pajamas made of organic cotton, as they allow your skin to breathe and effectively absorb moisture while keeping you comfortable throughout the night.
Can I wear Spandex during pregnancy?
Pregnant women should be cautious about wearing Spandex. While it can provide support during pregnancy, tight-fitting spandex garments can restrict blood flow and make temperature regulation more challenging.
Pregnant women may also experience increased sensitivity to fabrics and chemicals, making them more susceptible to skin reactions.
Though it’s not necessary to avoid spandex completely during pregnancy, we would advise taking extra caution with its use and limiting your duration of wear, choosing garments with lower spandex content, and changing immediately if sweating.
