4. The Truth About Textiles: Performance Fabrics, PFAS & Healthier Choices for Interior Designers

Episode 4: The Truth About Textiles: Performance Fabrics, PFAS & Healthier Choices for Interior Designers Are “performance” fabrics actually safe for our homes—or are they loaded with hidden toxic chemicals? In this episode of Design with Impact, I’m joined by Patty Grossman, co-founder of Two Sisters EcoTextiles, to break down what interior designers need to know about sustainable textiles, healthy upholstery, and non-toxic fabric choices. Patty shares eye-opening insights into the textile industry, including why fabric can contain up to 25% chemicals by weight, what toxic substances may be hiding in common upholstery and drapery fabrics, and why certifications like GOTS and OEKO-TEX matter when sourcing for clients. We also discuss the truth about recycled polyester, why it’s often a greenwashing tactic, and what designers can do right now to avoid specifying plastic-based fabrics like polyester, acrylic, and vinyl. If you’re an interior designer who wants to create healthier, more sustainable interiors without sacrificing style or durability—this episode is a must-listen.
