Harmonized garment-variant dataset for textile sorting and fibre-to-fibre recycling analysis

This record contains the complete archived release of a harmonized garment-variant dataset and preprocessing workflow derived from publicly accessible online product pages of H&M and Uniqlo in the United Kingdom and Australia.

The final dataset file, 6_JSONL_component_normalized.jsonl, contains 47,522 colour-specific garment variants. Each record includes harmonized product metadata, colour information, retailer-disclosed material composition, normalized material text, harmonized garment categories, and structured component-level material-composition information.

The release also includes six preprocessing scripts, five CSV documentation tables, and six TXT processing summaries documenting the transformation from retailer product-page records to the final component-normalized dataset. The associated GitHub repository contains the maintained documentation, preprocessing scripts, mapping tables, and processing summaries. The public release does not redistribute product images, screenshots, raw HTML, review text, or full webpage captures.
