Polyester fibres are very strong, so when a fibre end pokes out and tangles into a ball, it does not break easily and the pill stays attached to the fabric. In cotton, weak fibres break and the pills drop off by themselves.
That is why blends with a high polyester share can look worn sooner, especially in rubbing zones. The problem is reduced by combed or compact yarns, by low-pill polyester fibre and by finishing. Ask for a pilling test result for heavily used articles.
