👉 Yarn fumes are volatile organic compounds (VOCs) released when synthetic fibers, such as those found in many types of yarn, are agitated or heated. These fumes can contain a mix of chemicals like formaldehyde, acetaldehyde, and phthalates, which are common in the manufacturing process and can be inhaled during activities like knitting, crocheting, or even simply breathing in the air around the yarn. While typically present in low concentrations, prolonged exposure to these fumes can lead to respiratory irritation, headaches, and other health issues. However, many modern yarns are formulated with lower VOC content, and ventilation can help mitigate these effects, making the experience more comfortable for those who enjoy crafting with synthetic materials.
