FAQs About Fabric GSM Differences
1. What GSM range minimizes pilling in recycled cotton?
Recycled cotton’s shorter fibers increase pilling below 150 GSM. Aim for 180–220 GSM to stabilize the fabric. For added durability, blend with 30% polyester and use compact spinning techniques.
2. Can GSM adjustments help meet EU textile recycling laws?
Yes. Under the EU’s 2025 Textile Waste Directive, fabrics above 300 GSM are harder to shred mechanically. Designing within 120–250 GSM improves recyclability—lighter fabrics break down faster. Pair this with mono-material construction for compliance.
3. How do I communicate GSM changes to existing customers?
Position GSM adjustments as value-driven upgrades. For example: “We increased jeans from 250 GSM to 300 GSM for enhanced durability, your customers get 2x more wears.” Provide comparison swatches and stress-test videos.
