Determining the propensity for pilling, fluffing, or billowing of surface fabrics

Determining susceptibility pilling assesses a textile's resistance to pilling, fraying, or puckering on its surface after repeated rubbing or washing. These surface defects, common in fabrics, degrade the perceived visual quality of a product and are a frequent cause of customer complaints. Objectively measuring this susceptibility allows textile manufacturers and distributors to guarantee the durability and longevity of their products.

What is pilling and why test for it? Pilling refers to the formation of small balls of fibers on the surface of a fabric, caused by friction from use and washing. Ruffles and puckering are related types of surface degradation . These phenomena depend on the type of fibers, the weave or knit structure, and the finishing techniques applied. For textile manufacturers, anticipating this behavior is essential: a garment or upholstery fabric that pills quickly loses its appeal, generates returns, and damages the brand image. Testing allows for the qualification of a material before production, the comparison of suppliers or fabric qualities, and the documentation of compliance with specifications.

How is the analysis carried out?
The evaluation is performed according to recognized international standards, primarily ISO 12945 (pilling box or Martindale method) and ASTM D4970. The principle involves subjecting a fabric sample to controlled friction for a defined number of cycles, then visually comparing the resulting surface appearance to a calibrated rating scale (generally from 1, heavy pilling, to 5, no pilling). This standardized rating provides an objective and reproducible result, comparable from one laboratory to another. The choice of method and the number of cycles depends on the type of textile and its intended use.

Which textiles and applications?
This test applies to a wide range of products: clothing and apparel, upholstery fabrics (sofas, curtains, bedding), technical and functional textiles, as well as fabrics intended for intensive use. It is particularly relevant for items subjected to frequent rubbing or repeated washing, where the durability of the surface appearance is a key quality criterion.
