EU textile rules (Regulation 1007/2011) expect product pages to state a textile's fibre composition using the allowed Annex I fibre names, with percentages that add up to 100. This app checks the composition you enter against the Annex I list in six languages, explains problems in plain words, and displays a validated composition on your product pages in the shopper's language, with English as fallback. A timestamped CSV documents what you displayed and since when.

• Checks fibre names against the Annex I list in EN, FR, DE, IT, ES and PL
• Flags percentages that do not add up to 100, with plain-language reasons
• Suggests allowed names for trade names like Lycra, Tencel or polycotton
