products with a published composition

Every product listed in Known Supply's live catalogue is retrieved and its stated fibre composition read individually, from the Known Supply product page, Known Supply's own product data and its material labels. A fibre percentage for Known Supply is published only when 100% of the Known Supply catalogue has been read. Items Known Supply sells that carry no clothing textile, such as gift cards, packaging, jewellery and homeware, are excluded from the percentage rather than counted as a pass or a fail.

Not recorded (9): These products carry no fibre composition the brand publishes anywhere we can read. They are counted in the catalogue total but excluded from the fibre percentage, and linked so you can check them yourself.

How we scan. Every figure on this page comes from the Throne Standard scan: we read the fibre composition off each live product on the brand’s own site, style by style, and count only single-fibre plant cloth (cotton, linen, hemp) as natural. Animal fibres such as wool, silk and cashmere and plastic-based synthetics such as polyester, nylon and elastane sit outside the plant-fibre figure, and regenerated fibres such as viscose, bamboo, modal and Tencel are counted as semi-synthetic. Percentages are calculated over the styles that state a composition; anything unlabelled is shown separately.
