Criterion 1: Recyclability
Olefin is 100% recyclable via physical melting, producing 28% less CO₂ than polyester. Tests show recycled 200g/m² olefin retains 85% strength. Prioritize recycled olefin like the 200-220g/m² variant for foldable applications.

Criterion 2: Colorfastness & Pollution Control
3.0-4.5 colorfastness reduces dye wastewater by 60% (AATCC). Acrylic's 2000-hour rating means 5+ years without replacement, lowering production energy. Use pH-neutral cleaners for additional eco-benefits.

Criterion 3: Weight & Resource Efficiency
Heavier fabrics (e.g., 280g/m² acrylic) last 23% longer despite higher initial material use. Tests show 280g/m² requires 1.2 fewer replacements than 220g/m² olefin under UV exposure. Lightweight olefin cuts transport emissions by 12%.

Criterion 4: Production Certifications
SGS-certified fabrics comply with REACH regulations. The 1000-1500-hour spun polyester meets OEKO-TEX® Standard 100 Class II for skin contact.

Criterion 5: Third-Party Verification
Request reports containing:

• ΔE≤3.0 after 50 washes (ISO 105-C06)

• ≥20,000 Martindale abrasion cycles

• ≤75mg/kg formaldehyde (GB 18401-2010)

Case Study
A brand using 230g/m² recycled polyester achieved GRS certification, reducing annual emissions by 15 tonnes.
