Considerations

Very high carbon footprint from energy-intensive chemical production

Uses hazardous chemicals in manufacturing

Sheds microfibres and won't break down naturally

Makes garments harder to recycle when blended with other fibres

Reduces overall recyclability of blended garments

Strengths

Usually used in small percentages, limiting per-garment impact

Extends garment functionality and fit

Bio-based alternatives are emerging

Carbon Footprint Analysis
