Pilling Resistance Assessment
topic
Pilling testers including the ICI random tumble, Martindale, and circular locus methods subject fabric specimens to gentle multi-directional abrasion that entangles protruding fibres into surface pills; graded against ISO photographic standards from grade 5 (no pilling) to grade 1 (very severe pilling).
Role
Critical quality indicator for knitwear, fleece, and blended fabrics where surface fuzz formation impairs aesthetics and consumer perception of quality, directly influencing fibre selection, yarn twist, and fabric finishing strategies.
