The visual standards are most advantageous when the laboratory test specimens correlate closely in appearance with worn fabrics and show a similar ratio of pills to fuzz. Store the fabric rating standards and handle them under conditions that will preserve their original form and appearance.
What is our Random Tumble Pilling Tester used for? Firmly grasp the specimen by a corner and allow the vacuum suction to draw the specimen inside. Preparation of Apparatus Contact Supplier Start Order. Pills are caused to form on fabric by a random rubbing action produced by tumbling specimens in a cylindrical test chamber lined with a mildly abrasive material. It is advisable to have a separate set of in-house fabric rating standards for each surface effect to be rated.
NOTE 8—The use of air injection with all fabrics, woven or knitted, has been found to signi? ASTM D von The values stated in each system may not be exact equivalents; therefore, each system shall be used independently of the other.
Your comments are invited either for revision of this standard or for additional standards and should be addressed to ASTM International Headquarters. If the pills are concentrated d3521 any one strip adtm either fabric direction, or in any one portion of a specimen, report this condition.
NOTE 3—Full-strength adhesive or any dilution down to 1 part adhesive with 1 part water may be used see 7. NOTE 4—Although the asfm of glued or not glued specimens is acceptable, the measurements should not be compared. If a bias is found, either its cause must be found and corrected, or future test results must be adjusted in consideration of the known bias.
The rounded end of a glass asttm rod works well, also, but caution should be used to prevent breakage and possible injury from broken glass. In some cases the purchaser and the supplier may have to test a commercial shipment of one or more specific materials by the best available test method, even though the test method is not recommended for acceptance testing. Shipped in 15 days after payment.
A superscript epsilon e indicates an editorial change since the last revision or reapproval. Check, also, when test results appear questionable, or following a change in test equipment such as the use of a new shipment of cork liners.
Pilling Resistance of Textile Fabrics
China tester tool China a. Apparatus and Materials 6. After each test, clean the bottom of the weight by wiping with a cloth wetted in a solution of detergent and water. Compressed air is also injected into the chamber to assist in the tumbling action. If it is used for acceptance testing, it should be used with caution asmt the between-laboratory precision is poor. It is the responsibility of the user of this standard to establish appropriate safety and health practices and determine the applicability of regulatory limitations prior to use.
Clean around the shaft of the impeller using a sharp instrument, such as a pick needle, to remove trapped detritus.

To determine the pilling and fuzzing characteristics of textile fabrics. Within the text, the inch-pound units are shown in parentheses.
If a specimen wedges around the impeller without tumbling or lies inert on the bottom or side of the chamber, shut off the air, stop the machine, remove the face plate, and free the specimen. NOTE 6—The mass of a 6-mm long section of tex sliver is about 25 mg.
Counting the pills and weighing their number with respect to their size and contrast, as a combined measure of pilling resistance, is not recommended because of the excessive time required for counting, sizing, and calculating.
Pilling Resistance Testing of Textile Fabrics Using ASTM and AATCC
Testing before refurbishing may be adviseable. The test results from the two laboratories should be compared using a statistical test for unpaired data, at a probability level chosen prior to the testing series. These factors are not evaluated when pilling is rated solely on astn number of pills.
