  Définition

  The tendency of fibers to ball or roll up. It is common in all fabrics which are knitted from yarns which possess a hairy or wooly surface but is particularly pronounced in knitted fabric made from spun nylon yarn. Pilling results when loose fiber ends escape from low-twist knitting yarns spun on relatively short staples. The loose ends, especially at the points where the fabric is exposed to rubbing, collect on the surface of the material and ball up into rather unsightly fluff.
  
  Small accumulations of fibres on the surface of a fabric. Pills can develop during wear, are held to the fabric by an entanglement with the surface fibres of the material, and are usually composed of the same fibres as those from which the fabric is made.
  
  A process of forming small tangles of fibers. These tangles are defects produced when the surface of a material is rubbed either against itself or a foreign substance; the short fibers pull out of the fabric yarns and entangle themselves with the ends of one or more fibers still held in the yarn. The pill is held on the surface and can be removed only by breaking the fibers that hold it. Pilling is most prevalent in loosely twisted fibers. While historically this occurred principally in woolen and worsted materials, especially knit goods, some constructions of the newer synthetic fibers have been particularly troublesome in this respect. Polyester fibers, nylon, and in some cases acrylic, pill in certain constructions. The term "pilling" is used by the woolen, worsted and synthetic trades, and is usually applied to fabrics, although it is also used in connection with wool in earlier stages of manufacture.
  
  Formation of little balls of fibers called "pills" on the surface of a cloth. Caused by abrasion in wear.
