In home decoration, fabrics like curtains and bedding are essential elements, yet many people overlook the environmental impact of these "small" items. To enhance properties such as wrinkle resistance and flame retardancy, manufacturers often add chemical resins during production. Additionally, during the printing and dyeing process, a variety of dyes, auxiliaries, and finishing agents are used—many of which contain formaldehyde. If not properly treated, these substances can remain in the fabric and gradually release formaldehyde into the air, contributing to indoor air pollution.
Homes with large floor-to-ceiling windows or viewing windows typically require a significant amount of curtain fabric. This is why some homeowners prioritize pollution control during renovation, but even after everything is complete, they may still find high levels of indoor formaldehyde. One of the possible causes is the use of low-quality fabrics that haven’t been adequately processed.
So, how can you choose quality curtain fabrics when decorating your new home?
At the Red Star·May Kailong Zhengzhou building materials store, Xu Caihui, a designer specializing in fish curtains, emphasized that well-known brands usually offer reliable quality with strict certifications. Lower-end products, on the other hand, may have environmental concerns. “If the curtains have a strong, pungent smell, it could indicate the presence of residual formaldehyde,†she warned. “It’s best to avoid such products. When selecting colors, go for lighter shades, as they tend to have lower risks of formaldehyde and better color fastness.â€
Ma Li, the general agent for Mercure fabrics in Henan, also advised against using new curtains immediately. Instead, he recommended soaking them in clean water first and then hanging them in a well-ventilated area to dry naturally. This helps remove any harmful chemicals. Song Lei, a designer from Longfa Decoration, added that if a room has multiple windows, homeowners can mix different types of window coverings—like bamboo blinds or Venetian blinds—to maintain the aesthetic while reducing reliance on fabric curtains. After all, fabric isn’t the only option for modern interior design.
