1. Common Fabrics for Casual Tops and Bottoms and Their Features
Casual clothing commonly uses natural fibers (cotton, linen, silk, wool) and synthetic fibers (polyester, nylon, spandex).
Natural fibers: breathable, skin-friendly, eco-friendly.
Synthetic fibers: highly elastic, wrinkle-resistant, quick-drying, but often involve chemical additives during production.
2. Harmful Substances in Fabric Production
In the production of casual tops and bottoms fabrics, common harmful substances include:
Formaldehyde
Used for “wrinkle-free” and “anti-crease” finishes. Formaldehyde is a known allergen and carcinogen, which may cause skin irritation, rashes, and respiratory issues (verywellhealth.com).
Azo Dyes
Frequently used to dye polyester fabrics. When degraded, they can release carcinogenic amines and are common skin allergens (wired.com).
Other potentially harmful chemicals include PFAS (for water/stain resistance), plasticizers, and flame retardants (theguardian.com).
3. How to Reduce Exposure to Harmful Substances
To minimize contact with harmful substances in casual clothing:
Wash new clothes thoroughly before wearing – reduces residual formaldehyde and azo dyes (pmc.ncbi.nlm.nih.gov).
Choose natural fibers and certified organic fabrics – GOTS and OEKO‑TEX Standard 100 certified fabrics are safer.
Avoid clothing labeled “wrinkle-free,” “waterproof,” or “stain-resistant” without clear safety information.
Opt for breathable fabrics dyed with low-allergen or plant-based dyes.
