How do you test fabric for pilling?

The test methods for fabric pilling performance are mainly random tumbling pilling test methods, box-type pilling test methods and martindale pilling test methods. QINSUN is a textile testing equipment manufacturer who can provide testing equipment according to Method Ds.

Random Tumble Pilling Test Method:

Test Instrument: Random Tumble Pilling Tester.

A random tumble pilling tester is used to determine the wrinkle and pilling properties of textile fabrics. Precision high speed impeller to agitate the test specimens against the cork liner for a preset time controlled by a timer and audible alarm. Also, pressurized air is injected into the chamber to aid in the tumbling process of the ion. Laboratory standard compressed air supply required.

Standards:
ASTM D3512 DIN 53867 JIS L 1076

Ici Pilling Box Testmethod:
Test Equipment: ICI Pilling Box Tester

ICI Pilling Box Tester is used to quickly reproduce the formation of pilling on fabrics in a fraction of the time it takes with normal wear and tear . Then the surface
pilling properties and hook properties of woven and knitted fabrics are determined.
The ICI Pilling Tester conforms to IS012945-1, BS 5811, etc. The ICI Pilling Tester uses a universal drive system with 2 or 4 positions, an electronic digital counter and a sample mounting device. The machine accepts ICI pilling boxes and ICI pling drums.
Samples are mounted on polyurethane tubes and randomly shaken under defined conditions in a cork-lined box. The pilling is assessed visually after a defined period of tumbling.

Ici Pilling Box Standards:
GB/T4802.3, ISO 12945.1, BS5811, IWS TM152

Martindale Pilling Test Method
Test Equipment: Martindale Tester
The Martindale Abrasion and Pilling Tester is the standard method for determining the abrasion resistance of textiles or leather and resistance to pilling. The samples are re-rubbed using known abrasives at low pressure and in continuously alternating directions, and the amount of abrasion or pilling is compared to standard parameters. Adaptable to test a wide range of applications including textiles, socks, leather, coated upholstery, carpet, wood and shirt collars. Four models are available, with 4, 6, 8 and 9 abrasion.

Martindale Tester Standards:
Abrasion: GB/T 21196.2, GB/T 13775, ISO 12947 , ASTM D4966, IWS TM 112, M&S P19, Next 18, SN 198529, TWC 112, JIS L1096 (
ISO17076-2 ball plate method, optional)

Pilling: GB/T 4802.2, ISO12945-2, ASTM D4970, IWS TM 196, M&S P17, Next TM26, SN 198525
