Your comments are invited either for revision satm this standard or for additional standards and should be addressed to ASTM International Headquarters. Allow the chamber to dry before the next use. Specimens should be staggered in such a manner that no two specimens contain the same yarns. Within the text, the inch-pound units are shown in parentheses.

Precision and Bias The observed resistance to pilling is reported using an arbitrary rating scale. NOTE 4—Although the d512 of glued or not glued specimens is acceptable, the measurements should not be compared. These factors are not evaluated when pilling is rated solely on the number of pills. The development of pills may be accompanied by other surface phenomena such as loss of cover, color change, or the development of fuzz.

No universal standard fabric is available.

If a specimen astmm 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. Historical Version s – view previous versions of standard. NOTE 5—If there is not sufficient material to provide three standard-size specimens, run with the available number of specimens rather than adding a specimen from another asstm, since there may be a strong interaction between fabrics which will create misleading results.


If you feel that your comments have not received a fair hearing you should make your views known to the ASTM Committee on Standards, at the address shown below.

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.

Users of this standard are expressly advised that determination of the validity of any such patent rights, and the risk of infringement of such rights, are entirely their astn responsibility.

Vacuum all specimens in this manner. Discard these and repeat the test with new specimens. This test method has no known bias.

Your comments will receive careful consideration at a meeting of the responsible technical committee, which you may attend.

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. The procedure is generally applicable to all types of woven and knitted apparel fabrics. Other materials with established test values may be used for this purpose. To eliminate any tendency for the liner to rotate, tape atsm outside edge of the liner to the chamber wall at the butt joint with a short piece of mm 1-in.

Pilling Resistance Testing of Textile Fabrics Using ASTM and AATCC

To determine the pilling and fuzzing characteristics of textile fabrics. This experience should be borne in mind when adopting levels of acceptability for any series of standards. NOTE 2—An adequate speci? Combining values from the two systems may result in non-conformance with the standard. Individual reprints single or multiple copies of this standard may be obtained by contacting ASTM at the above address or at phonefaxor service astm.

Avoid areas with wrinkles and other distortions. Store the fabric rating standards and handle them under conditions that will preserve their original form and appearance. China home tester China bill tester China unit tester.


Pilling Resistance of Textile Fabrics

Firmly grasp the specimen by a corner and allow the vacuum suction to draw the specimen inside. China tester tool China a. A series of standards, based on graduated degrees of surface change of the fabric type being tested, may be set up to provide a basis for subjective ratings.

For fabric components of fabricated systems use the entire system. Random Tumble Pilling Tester. Contact Supplier Start Order. If it is used for acceptance testing, it should be used with caution because the between-laboratory precision is poor.

There is no independent, referee method by which bias may be determined. Testing before refurbishing may be adviseable. The side against the chamber may or may not have been used.

As a minimum, the test samples should be used that are as homogeneous as possible, drawn from the material from which the disparate test results were obtained, and randomly assigned in equal numbers to 3d512 laboratory for testing. If the liner being checked has been contaminated, the pilling level on the standard rating fabric will be different than historical results obtained when testing as in NOTE 6—The mass of a 6-mm long section of tex sliver is about 25 mg.

The pilling resistance of a speci? As a minimum, the test samples should be used that are as homogeneous as possible, drawn from the material from which the disparate test results were obtained, and randomly assigned in equal numbers to each laboratory for testing.
