Cotton is a plant fibre used in clothing and home textiles. The finished fabric tells two stories: what its fibres are made from, and how its yarns are arranged. Reading both gives a more useful picture than judging softness alone.

- Material family: Natural cellulose fibre
- Where to look: T-shirts, towels, denim and bedding
- Useful context: Fibre content label and fabric construction

## What to look for

Look closely at the surface: loops suggest a knit, while crossing yarns show a weave. Capture the whole garment as well as a close detail. Those structures describe the fabric; a cotton-rich blend can share the same construction as another fibre mix.

## Make a useful comparison

Cotton preparation affects absorbency: natural waxes are removed during scouring for absorbent applications. Fabric finishes also change the way the surface behaves. A photograph helps document texture and construction, while the sewn-in label provides the stated fibre percentages.

## Explore it with Materium

Try a labelled T-shirt as a personal reference. Photograph its surface in even light, explore it with Materium, and keep the label photograph alongside your notes. That gives future fabric comparisons a familiar starting point.

## Care, reuse and recycling context

Keep usable textiles in use through care, repair or reuse. For worn-out items, check what the textile collector accepts; fibre blends, coatings and the condition of the item can affect the route.
