Acrylic Fabric
Synthetic wool substitute
Also seen as: acrylic fibre, polyacrylonitrile fibre, synthetic wool, faux wool
At a glance
Acrylic is a synthetic wool-substitute used in sweaters, blankets, scarves, gloves, and carpets. It's soft, cheap, and warm-feeling, but it pills heavily, sheds microfibres, and can hold residual chemicals from the manufacturing process. The fibre itself is generally low concern; the bigger issues are shedding, dyes, and finishes. Lower production volume than polyester or nylon, but used in items that often touch skin closely.
Quick facts
- What it isSynthetic textile fibre (polyacrylonitrile)
- Main jobSoft, warm, wool-like fabric for sweaters, blankets, and accessories
- How exposure happensSkin contact, microfibre dust, residual manufacturing chemicals
- Most relevant forSensitive skin, eczema-prone households, baby blankets
- Easy to spot?Yes — "acrylic" on garment labels
- US snapshotFibre labelling required; no specific regulation beyond general textile rules.
- EU snapshotREACH covers chemical finishes and residues.

What to do about it
Wash new acrylic items before first wear. For baby blankets and items used against sensitive skin, choose cotton, organic wool, or bamboo instead.
Better choices
- Wool, cotton, or bamboo for items worn against skin
- Organic cotton or merino wool for baby blankets and clothing
- Wash new acrylic before wearing to remove finishing residues
Common questions
Each answer is tagged with how settled the evidence is: Established, Estimate, or To check.
What is acrylic in simple terms?Established
Acrylic is a synthetic fibre made from polyacrylonitrile, a petroleum-derived polymer. It's spun into yarns that imitate the look and feel of wool — softer than polyester, warmer-feeling, but with very different properties (it pills heavily and doesn't insulate as well when wet).
Why is it used in everyday products?Established
Cheap, soft, fluffy, machine-washable, doesn't shrink. Used for items that need wool-like softness at a lower price point — sweaters, knit blankets, beanies, scarves, soft toys.
What names does it go by on labels?Established
Acrylic, acrylic fibre, modacrylic, polyacrylonitrile fibre. Branded versions include Orlon, Acrilan, Dralon, Courtelle.
Where do we commonly find it at home?Established
Sweaters, knit blankets, scarves, gloves, beanies, faux fur, soft toys, throw blankets, some carpets, and synthetic makeup brushes. If it feels wool-like but the label says synthetic, it's probably acrylic.
How does exposure happen?Established
Skin contact (with knitted items worn against the body) and inhalation of shed microfibres from blankets and carpets. New acrylic items can also off-gas mild residual solvents or finishing chemicals for the first few weeks.
How does it affect women, especially during pregnancy?To Check
The fibre itself is low concern. Acrylic blankets and throws don't pose a major direct health issue. Washing new items before use removes residual finishing chemicals — a low-cost precaution.
How does it affect men's health and fertility?To Check
No specific concerns documented.
How does it affect babies, children, and teenagers?Estimate
Slightly more relevant. Baby blankets, soft toys, and knitwear made of acrylic are mouthed and held against skin extensively. Cotton or wool alternatives are widely available for baby items. For older kids, the main consideration is the chemistry of any dyes or finishes — wash new items before first wear.
Does it affect older adults differently?To Check
No specific signal.
What does the strongest evidence say?Estimate
Acrylic fibres are broadly considered stable in normal use. The strongest research interest is in microfibre shedding (like all synthetic textiles) and in residual solvent emissions from new items, especially in confined or poorly-ventilated spaces.
How serious is the risk from normal daily use?Estimate
Low for adults using washed acrylic items. Lower-moderate for new acrylic items in babies' rooms (residual off-gassing) and for households where acrylic carpets dominate (microfibre dust).
What are safer alternatives?Established
Wool (especially merino), cotton, alpaca, bamboo, or cashmere for knitwear and blankets. Organic cotton or wool for baby items. Real wool is warmer when wet and biodegradable.
How easy or hard is it to avoid?Estimate
Easy. Natural-fibre alternatives are widely available, often at similar prices for cotton (more for wool). Read garment labels.
What's one simple first step right now?To Check
For your next baby blanket, kids' beanie, or warm throw — pick cotton or wool instead of acrylic. Same warmth, fewer concerns, and they tend to wash and wear better long-term.
What this means for youEstimate
Acrylic isn't the worst fibre, but it's one of the easier to avoid. Where you have a choice — especially for baby items, sleepwear, and blankets — natural fibres are a clear upgrade. Existing acrylic items in the house aren't worth replacing just for this.
Where can I find reliable information?To Check
Textile microfibre studies (PMC), and industry transparency reports from natural-fibre certifications like GOTS. See References below.
