Check surface appearance
ACT lists pilling under physical properties for woven indoor fabrics. Ask the supplier for the pilling method and result. Compare a retained sample with a handled sample to discuss fuzz or raised fibres with the buyer.
Check wear evidence separately
Request the abrasion method and exact construction tested. Use the number with the intended application and the rest of the specification. A high abrasion count cannot answer how much visible pilling the customer will accept.
