At a closer look, textiles are a combination of fibres forming flexible materials. Many of these fabrics are blends of natural fibres like wool, silk, or cotton and synthetic fibres such as nylon, polyester, or polyamide.
Depending on their field of application, the fibres are treated and refined in different ways. Examples are dyeing, anti-microbial finishing, or a treatment with cyclodextrines as odour absorbents.

- prohibited azo compounds
- allergenic disperse dyes
- anti-microbial finishing agents (e. g. triclosan, formaldehyde, dimethyl fumarate)
- mothproofing agents (e. g. permethrin, Eulan)
- flame retardants
- organotin compounds
