Acrylic and Synthetic Yarns
Acrylic is the dominant low-cost yarn fibre in hand-knitting. Machine-washable, machine-dryable, hypoallergenic, inexpensive — but lacks the breathability, warmth-to-weight, and longevity of natural fibres.

When to choose acrylic
Charity knitting where the recipient may not handwash. Children's clothes that need to survive frequent machine washing. High-allergy environments. Projects where cost is the primary constraint.
Limitations
Does not breathe — wearer overheats easily. Pills heavily, especially in low-cost acrylics. Plastic origin means acrylic does not biodegrade. Aggressive heat (high dryer or iron) can melt the fibres.

Higher-quality acrylics
Modern premium acrylics (Cascade Heritage, some Berroco lines, parts of the Caron Cake range) feel substantially better than budget acrylic. The price gap with low-end wool is small.
Acrylic vs nylon
Nylon is occasionally blended with wool (especially in sock yarn) for added durability — typically 20–25% nylon to a wool blend. Pure nylon yarns are uncommon and best avoided in hand-knitting.

Tips
- For charity knitting and children's clothes, acrylic is often the right choice for practical reasons.
- Premium acrylics feel substantially better than budget acrylic; the price difference is modest.
- Avoid high heat (dryer, iron) — acrylic melts.
In depth
Acrylic has been the dominant low-cost knitting fibre since the 1950s. Its washability and price make it the practical choice for many situations even though natural-fibre purists dismiss it. Modern premium acrylics have closed much of the quality gap with wool, particularly for projects where care and cost are important.
