Pilling Assessment
Laboratory test methods designed to evaluate fabric surface degradation under multidirectional friction help predict apparel wear behavior. The martindale pilling test uses a specific Lissajous pattern to rub fabric specimens against each other or a standard abradant cloth. This method assesses the formation of fiber fuzz and small pills on the fabric surface over a specified number of rubbing cycles.
Rubbing Action
Continuous movement across the specimen surface applies friction in all directions to simulate the wear that occurs during garment use. When conducting a martindale pilling test, the machine runs for predetermined intervals such as five hundred or one thousand rubs. This rubbing creates a realistic breakdown of fiber structures.
Visual Comparison
Specimens are evaluated in a standardized viewing cabinet to grade surface changes. The martindale pilling rating uses a five-step visual scale where five represents no change while one indicates severe pilling. These grades provide a metric for comparison.
Fabric Suitability
Knitwear and soft woven fabrics are particularly vulnerable to surface friction during daily wear. Analyzing results from the martindale pilling test helps garment buyers select appropriate fabric constructions for high-wear areas like sleeves or pockets. Manufacturers use these grades to reject or accept batches before bulk assembly, which maintains final garment quality and avoids customer returns.
