Use fibre information to identify care questions, then follow the finished item’s label. This library provides bounded references for cotton, wool, silk, linen, polyester and viscose categories. Some evidence concerns sheets or named garment types; it does not establish one washing routine for every item made from that fibre.
Why finished care instructions come first
Dyes, treatments, trim and construction can change the allowed method. A general cotton-sheet routine cannot approve washing a cotton item with restricted trim. Likewise, a silk label may require a route different from a general washable-fabric treatment.
Whirlpool’s fabric examples concern sheets. Persil’s silk guidance and Woolmark’s wool references address their stated item scopes.

Use the library to choose the next check
Select the fibre category and read the source scope alongside the notes. For wool, suitable detergent and drying position can depend on the item. For bamboo-derived viscose, sheet guidance is not evidence for every viscose garment. Blends and an unknown finish still require the actual label.
Use the care-label decoder for the finished instructions and the stain finder only when its fabric conditions apply. The library is reference context, not a substitute for an unreadable product label.
Common questions
Does wool always mean hand wash only?
No. Follow the finished label. Some items have express machine-washing or drying permissions with specific conditions.
Can sheet guidance be applied to every garment?
No. The source scope matters; a named sheet category does not establish a universal fibre routine.
What should I do with a blend or missing label?
Ask the product maker for the finished care instructions. Fibre names alone leave construction and finish restrictions unresolved.
