Acrylic clothing carries significant environmental and potential health concerns that consumers should understand before purchasing. While this synthetic fabric offers warmth, affordability, and durability, its production relies on petroleum-based chemicals, releases harmful microplastics during washing, and takes hundreds of years to decompose in landfills.
What Exactly Is Acrylic Fabric?
Acrylic fiber emerged as a synthetic alternative designed to mimic wool’s warmth and softness at a fraction of the cost. The primary raw material is polyacrylonitrile, derived from crude oil and natural gas. During production, acrylonitrile monomers undergo polymerization, creating long polymer chains that manufacturers then dissolve in solvents and extrude through spinnerets to form delicate fibers.
This manufacturing process demands substantial energy. Studies indicate acrylic production requires approximately 175 MJ/kg of fiber—making it 30% more energy-intensive than polyester and over three times more demanding than cotton.
Environmental Concerns: A Microplastic Nightmare
Microplastic Pollution
Every time you wash an acrylic sweater, tiny synthetic fibers shed into wastewater systems. Research reveals that acrylic fabrics release nearly 1.5 times more microplastic particles than other synthetic materials when washed. These microscopic fragments—invisible to the naked eye—flow through sewage networks into rivers and oceans, where marine life ingests them.
Because microfibers possess high surface-area-to-volume ratios, they act as sponges for environmental pollutants, absorbing trace metals and persistent organic contaminants before entering the food chain.
Non-Biodegradable Nature
Unlike cotton or wool, acrylic products persist in landfills for centuries without breaking down. Synthetic textiles now account for 60% of global fiber production, with acrylic, polyester, and nylon contributing significantly to 35% of primary microplastics entering marine environments.
Health Risks: What Touches Your Skin Matters
Skin Irritation and Allergies
Acrylic’s synthetic composition creates problems for sensitive skin. The fabric lacks breathability, trapping moisture, heat, and oils close to the body. This environment can trigger:
- Itchiness and redness from chemical residues or rough fiber texture
- Exacerbated eczema or dermatitis symptoms
- Bacterial buildup leading to body odor
Chemical Exposure Concerns
The U.S. Environmental Protection Agency raised concerns as early as 1979 about residual monomers in acrylic fabric potentially being carcinogenic. The production process uses acrylonitrile, classified as a probable carcinogen, and workers with acute exposure face increased cancer risks. When body temperature rises beneath non-breathable acrylic, the fabric may release chemical residue from fibers more readily.
The Benefits: Why People Still Choose Acrylic
Despite drawbacks, acrylic remains popular for practical reasons:
| Feature | Acrylic Performance |
|---|---|
| Warmth | Crimped fibers trap air pockets, mimicking wool’s insulation |
| Weight | Lightweight yet effective in cold weather |
| Durability | Resists wear, mold, and mildew; maintains shape over time |
| Affordability | Significantly cheaper than wool or cashmere |
| Care | Machine washable, no shrinkage, dries quickly |
| Color retention | Holds vibrant, long-lasting dyes |
Acrylic vs. Natural Fibers: A Direct Comparison
| Factor | Acrylic | Cotton | Wool |
|---|---|---|---|
| Source | Petroleum-based synthetic | Natural plant fiber | Natural animal fiber |
| Breathability | Poor—traps heat and moisture | Excellent—cool in hot weather | Moderate—regulates temperature |
| Biodegradability | Non-biodegradable | Fully biodegradable | Fully biodegradable |
| Skin Safety | May irritate sensitive skin | Hypoallergenic, safe for babies | Generally safe but may itch |
| Environmental Impact | High energy use, microplastic pollution | Lower with organic options | Lower CO2 emissions |
Sustainable Alternatives and Solutions
Eco-Friendly Fabric Choices
Natural fibers outperform synthetics in sustainability metrics. Wool production emits approximately 5 kg CO2 equivalent per kilogram, while synthetic alternatives exceed 10 kg. Better options include:
- Organic cotton and hemp—biodegradable, requiring fewer chemicals
- Tencel (Lyocell)—wood pulp-derived, uses 99% recyclable solvents
- Recycled acrylic yarn—reduces virgin material demand
- Bamboo fiber—naturally soft and biodegradable
Reducing Microplastic Release
If you already own acrylic garments, Guppyfriend wash bags can catch loose fibers during laundering, while specialized laundry filters remove up to 95% of microplastics.
Key Takeaways
- Acrylic clothing sheds microplastics during every wash, contributing to marine pollution and entering food chains
- Production is highly energy-intensive—30% more than polyester—and relies entirely on fossil fuels
- Potential health concerns include skin irritation, reduced breathability, and exposure to residual chemicals from manufacturing
- Benefits like warmth, durability, and affordability explain acrylic’s continued market presence
- Natural alternatives such as organic cotton, wool, hemp, and Tencel offer more sustainable choices with lower environmental footprints
Frequently Asked Questions (FAQ)
Is acrylic clothing safe to wear on skin?
Acrylic is generally considered safe for most people but may cause irritation for those with sensitive skin or eczema. The fabric’s poor breathability traps moisture and heat, potentially triggering rashes or discomfort. Choosing cotton or bamboo alternatives offers better skin compatibility.
Does washing acrylic release microplastics into water?
Yes. Acrylic fabrics shed approximately 1.5 times more microplastic fibers than other synthetics during machine washing. These particles enter waterways through sewage systems and accumulate in marine ecosystems. Using a microfiber-catching wash bag significantly reduces this pollution.
Why is acrylic considered bad for the environment?
Three main factors drive environmental concerns: acrylic requires petroleum-based raw materials, demands 175 MJ/kg of energy during production (more than polyester or cotton), and persists in landfills for hundreds of years without biodegrading.
Can acrylic fabric cause cancer?
The raw material acrylonitrile used in production is classified as a probable carcinogen by health authorities. While casual wear poses low risk, the CDC notes that repeated skin contact with acrylic fibers may increase exposure to residual chemicals. Research on long-term consumer effects remains limited.
What are the best alternatives to acrylic for warmth?
Merino wool provides superior insulation and temperature regulation naturally. For budget-conscious shoppers, high-quality recycled wool blends or Tencel-based fabrics offer warmth with significantly lower environmental impact. Hemp and organic cotton also work well for layering.
How can I reduce harm if I already own acrylic clothing?
Wash acrylic items less frequently and in cold water to minimize fiber shedding. Invest in a Guppyfriend bag or install a laundry filter that captures up to 95% of microplastics. When garments wear out, dispose responsibly rather than sending to landfill where possible.
Is recycled acrylic yarn more sustainable?
Recycled acrylic reduces demand for virgin petroleum materials and diverts waste from landfills. However, it still sheds microplastics during washing and remains non-biodegradable at end-of-life. It represents a better choice than virgin acrylic but falls short of natural fiber sustainability.
