An automated pilling grading instrument is used to Analyse the pilling formation and give grades accordingly.


The PillGrade system is a 3D fabric scanning system that is a kind of patent-pending technology to objectively and repeatedly grade fabric swatches for surface properties. 


In this instrument, a pilling-formed specimen (Output of ICI or Martindale pilling instrument) is placed on the platform.


The instrument scanned the specimen by the light source into the closed chamber.


The system gave outputs of pilling and fuzziness data, in addition to the 1-5 pilling grade according to both ASTM and ISO standards. 


PillGrade’s method for inspection allows the instrument to scan and grade fabrics according to weight, colour, and pattern. 


In this instrument, pilling is scanned according to its templet training, templet matching, segmentation, extraction of pill ball, size covered by ball/area of each pill, contrast, and density of pill.


This is done by gathering various temples of pilled fabric and comparing them with specimen scanned photographs. According to this analysis final results come and according to that pilling, grade shows in the display.


In this instrument, Any type of fabric can be graded like woven, nonwoven, knit, fleece, automotive, or any blend or material.
Fabric patterns and colours are “invisible” to PillGrade. 


Generally, the Specimen size for this instrument is in the range of 4” x 4” (10 cm x 10 cm) to 6” x 6” (150 mm x 150 mm).


This instrument provides data on the number of pills, histogram of pill sizes, average pill size, pill density (pill / in2 and pills / cm2), and fuzz loft.
