Polyester-cotton blend or 100% cotton for T-shirts?

Main answer

Polyester-cotton blends dry faster, wrinkle less and shrink less than cotton, but they breathe less and can pill, while 100% cotton feels natural and absorbs well but shrinks and wrinkles more. Choose by use, climate, price and care routine, and state the blend ratio on the label.

What a blend changes

Polyester adds strength, quick drying, shape retention and wrinkle resistance. Cotton adds softness, absorbency and a familiar natural feel. A blend balances the two, and the ratio decides the result: more polyester gives more of the synthetic traits. Blends are common in uniforms, workwear and promotional wear.

Comfort

Cotton feels natural and absorbs sweat, but stays damp and slow to dry once wet. A blend dries faster but can feel warmer or clammy to some wearers, as polyester absorbs little water. Comfort also depends on yarn, knit and finish, so test samples in your climate rather than rely on the fibre alone.

Durability and care

Blends usually shrink and wrinkle less and keep their shape through many washes. Pilling can be an issue, as polyester pills hold on to the surface. Cotton shirts shrink and fade more, but pills fall off more easily. Check the heat tolerance of the blend, as high heat can set wrinkles.

Matching to the job

For uniforms washed often in hot machines, a blend usually keeps shape and colour better. For casual wear in warm weather, many customers prefer cotton. For printed promotional items, price and print method often decide, so ask your decorator which fabric they prefer.

Print, price and labelling

Cotton takes many prints and dyes easily. Blends may need special inks or dye processes, and heather effects are common in blends. Prices vary with fabric quality. Labels must list the fibres by generic name and percentage under US textile rules. See T-shirt fit and fabric and custom T-shirt manufacturing.
