|What Is Fabric Pills||
As described in ISO 12945-1, “pills are formed when fibres on a fabric surface “tease out” and become entangled during wear”. The level of pilling is determined by the rate of a) fibre entanglement leading to pill formation; b) development of more surface fibre; c) fibre and pill wear-off. The rate of these process depend on the fibre, yarn and fabric properties.
