Testing before refurbishing may be adviseable. Discard these and repeat the test with new specimens. Add another 25 mg see Note 6 of 6-mm 0.

Pilling Resistance of Textile Fabrics

To form pills with appearance and structure that resemble those produced in actual wear, small amounts of short-length gray cotton? Firmly grasp the specimen by a corner and allow the vacuum suction to draw the specimen inside. China home tester China bill tester China unit tester. It is advisable to have a separate set of in-house fabric rating standards for each surface effect to be rated.

This standard is subject to revision atm any time by the responsible technical committee and must be reviewed every? Within the text, the inch-pound units are to be regarded as the standard. Shipped in 15 days after payment. Combining values from the two systems may result in nonconformance with the speci? 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.

If e3512 liner being checked has been contaminated, the pilling level on the standard rating fabric will be different than historical astn obtained when testing as in The pilling resistance of a specific fabric in actual wear varies more with general conditions f3512 use and individual wearers than in replicate fabric specimens subjected to controlled laboratory tests.

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. 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. The side against the chamber may or may not have been used. Specimens should be staggered in such a manner that no two specimens contain the same yarns.


Vacuum-clean the test chamber. This test method has no known bias. 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.

The pilling resistance of a speci? NOTE 4—Although the use of glued or not glued specimens is acceptable, the measurements should not be compared.

To eliminate any tendency for the liner to rotate, tape the outside edge of the liner to the chamber wall at the butt joint with a short piece of ast 1-in. The test results showed that those fabrics with average ratings less than or equal to 2. Since the overall acceptability of a speci?

Apparatus and options for visual evaluation are listed in Table 1. Since the overall acceptability of a specific fabric is dependent on both the characteristics of the pills and the other factors affecting surface appearance, it is suggested that fabrics tested in the laboratory be evaluated subjectively with regard to their acceptability and not rated solely astk the number of pills developed.

Random Tumble Pilling Tester uses stainless steel impellers rotate within individually lit aluminium chambers constantly tumbling test fabrics against cork liners for a pre-determined time controlled by a timer and audible alarm.

After each test, clean the bottom of the weight by wiping with a cloth wetted in a solution of detergent and water. If a bias is found, either its cause f3512 be found and corrected, or future test results must be adjusted in consideration of the known bias.


Pilling Resistance Testing of Textile Fabrics Using ASTM and AATCC

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. Cotton sliver is available commercially. Referenced Documents purchase separately The documents listed below are referenced within the subject standard but are not provided as part of the standard. Your asttm will receive careful consideration at a meeting of the responsible technical committee, which you may attend.

Take the specimens evenly spaced across the width of the laboratory sample or from three different panels in a garment.

Summary of Test Method 4. 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.

Each test facility must decide on an appropriate fabric.

Apparatus and Materials 6. 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.

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. If the pills are concentrated in ast, one strip in either fabric direction, or in any one portion of a specimen, report this condition.
