What is Abrasion and Pilling Tester and Methods?

Abrasion and Pilling Tester:

Abrasion and Pilling tester machine is used to determine the resistance of the textiles fabric after rubbing against a standard abradant (a special woven worsted fabric) that is assessed by visual comparison after predetermined no. of cycles.

  • Machine name: Abrasion and Pilling tester.
  • Model number: Nu-Martindale 404
  • Machine origin: England
  • Brand name: James H. Heal & Co. Ltd
  • Test Name : Random Pilling

Apparatus

  • Random Pilling Tester .
  • Cork cylinder Liner about 146mm wide by 452mm long cut from 1.5mm thick flat surface .
  • Air Injection Device to give 14-21 kpa (2-3psi)air pressure in each chamber
  • Adhesive White all Purpose for sealing edges specimen
  • Vacuum cleaner
  • Cotton Sliver 4301tex fine American
  • A set of five photographs, 105-mm square (4.13 in.), numbered 1 to 5 illustrating varying degrees of pilling from “very severe pilling” to “no pilling” such as Adjunct The photos should have a dull matte finish and Be of the same size as the tested specimen.

Pre-Treatment

Samples may be washed or dry cleaned before cutting the test
specimens, using conditions appropriate for the fabric end use
or conditions agreed upon by all interested parties.

No of Specimen/Specimen Size

Sample = 4 Pcs (105mm×105mm) 45° Diagonally

Testing Procedure

  • Seal the edges of all specimens to a width not exceeding 3 mm (.13 in.) on the face of the fabric with adhesive. Hang the specimens on racks until dry, and in any case for at least 2 h
  • After every hour of machine running time, remove theliner and clean the impeller by wiping with a cloth wetted in a solution of detergent and water. Allow the chamber to
    dry

Evaluation

Turn on the light of the viewing cabinet , Place the tested specimen and Original(Left Tested & Right Original) one onto the viewing cabinet ,
Using the viewing apparatus and option selected from and either
suitable fabric or photographic standards subjectively rate
the appearance of the face (as indicated by the markings and after the respective tumbling times)
of each specimen, using the following scale
5—no pilling
4—slight pilling
3—moderate pilling
2—severe pilling
1—very severe pilling
Average the ratings for the three specimens from each laboratory
sampling unit and the average for the lot.Check the pilled
specimens for non uniformity of pilling

PILLING RESISTANCE (POLAR FLEECE ONLY)

1 SCOPE:
This In House Test Method describes the method of test in order to determine the resistance of a knitted or woven fabric to pilling or change in surface appearance.

2. PRINCIPLE
The correct number of test specimens are to be prepared and tested as specified within this test method in order to achieve a performance assessment of the product/fabric as described within the scope.
3. EQUIPMENT:
3.1 WASCATOR Washing Machine
3.2 Drying Racks
3.3 Viewing cabinet from which external light is excluded.
4. CONDITIONING

The test specimens are to be conditioned in the standard atmosphere of 65% Relative
Humidity (RH) +/- 2% and 20°C +/- 2°C for a minimum of 16 hours. All tests should also
be carried out in this atmosphere. (after wash/dry process – before grading)

5. HEALTH & SAFETY

Not applicable.

6. PREPARATION OF TEST SPECIMENS/MATERIALS

Not applicable.
7. TEST PROCEDURE

7.1 Wash a fabric sample (in accordance with the Care Label instructions), Retain some original fabric for final comparison.
7.2 Dry flat on plastic mesh trays.
8. ASSESSMENT/RESULTS OF TESTED SPECIMENS
8.1 Mount the tested specimen with piece of untested fabric.
8.2 Grade the sample in the viewing cabinet, rate the sample according to the following table of assessment: (Half grades may be given).
Grade Descriptive Method
5 No Visual Change
4 Slight Surface Fuzzing
3 Moderate Surface change/matting or isolated pills
2 Significant surface change and/or matting
1 Distinct surface change and/or matting.
