ASTM D 3512, Standard Test Method for Pilling Resistance and Other Related Surface Changes of Textile Fabrics: (Random Tumble Pilling Tester)

Scope: Determines the resistance to the formation of pills and other related surface changes of textile fabrics using the random tumble pilling tester.

  • Specimens are laundered 3 times and then conditioned in atmospheric conditions for textiles
  • The edges of 3 4”x4” squares cut on the bias are sealed with glue and allowed to dry
  • The 3 specimens are placed in the pilling chamber along with 25mg of gray-dyed cotton fiber and tumbled for 30 minutes
  • The specimens are evaluated in a viewing apparatus against photographic standards (ASTM ADJD 3512) or in house fabric standards

 

ASTM D 4970, Standard Test Method for Pilling Resistance and Other Related Surface Changes of Textile Fabrics: Martindale Tester

Scope: Determines the resistance to the formation of pills and other related surface changes o textile fabrics using the Martindale tester*

  • Specimens are laundered 3 times and then conditioned in atmospheric conditions for textiles
  • Specimens are mounted in the bottom table as well as in the specimen holder
  • A lissajous figure is used to perform one cycle. A cycle consists of the 16 movements in the lissajous figure
  • The machine is run for 100 cycles and evaluated
  • It may be run up to 1000 cycles with 100 cycle evaluation intervals
  • The specimens are evaluated in a viewing apparatus against photographic standards (ASTM ADJD 3512) or in house fabric standards
  • Specimen holder pressure is 3kPa

*Note: This test method is not suitable for fabrics thicker than 3mm (0.125 in.) because such fabrics cannot be mounted in the specimen holder

 

ASTM D 3511, Standard Test Method for Pilling Resistance and Other Related Surface Changes of Textile Fabrics: (Brush Pilling Tester)

Scope: Determines the resistance to the formation of pills and other related surface changes of textile fabrics using the brush pilling tester.

  • Sample is conditioned in atmospheric condition for textiles
  • 6 specimens are cut in 9" X 9" squares, two each from the right, center, and left areas across the width of the sample
  • Specimens are mounted and brushed for 4 minutes
  • Specimens are then mounted face-to-face and ran for 2-minutes
  • The samples are evaluated in a viewing apparatus against photographic standards (ASTM ADJD 3512) or in house fabric standards

 

 


AATCC/ASTM TS-008, Procedure for Appearance of Apparel and Other Textile End Products After Repeated Home Laundering

Scope: Evaluates the overall general appearance of a garment and other textile product after repeated home laundering

  • Specimens are laundered 5 times and then conditioned in atmospheric conditions for textiles
  • The specimens are evaluated in a viewing apparatus against photographic standards (ASTM ADJD 3512) or in house fabric standards and the original unlaundered control
