Textile Random Tumble Pilling Tester. Not exactly what you want? The observed resistance to pilling is reported using an arbitrary rating scale. Precision and Bias To determine the pilling and fuzzing characteristics of textile fabrics.

Counting the pills and weighing their astj with respect to their size e3512 contrast, as a combined measure of pilling resistance, is not recommended because of the excessive time required for counting, sizing, and calculating. Strips indicate that different yarns may have been used in making the fabric being tested. 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.

No universal standard fabric is available. If a bias is found, either its cause must be found and corrected, or future d35512 results must be adjusted in consideration of the known bias.

The degree of fabric pilling is evaluated by comparison of the tested specimens with visual standards that may be actual fabrics, or photographs of fabrics, showing a range of pilling resistance. The visual standards are most advantageous when the laboratory test specimens correlate closely in appearance with worn fabrics d351 show a similar ratio of pills to fuzz.

Pilling Resistance of Textile Fabrics

The development of pills may be accompanied by other surface phenomena such as loss of cover, color change, or the development of fuzz. Laboratory standard compressed air supply required.

Combining values d312 the two systems may result in nonconformance with the speci?

The observed resistance to pilling is reported on an arbitrary scale ranging from 5 no pilling to 1 very severe pilling. 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.

Pilling Resistance Testing of Textile Fabrics Using ASTM and AATCC

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. Apparatus and options for visual evaluation are listed in Table 1.

If any of the specimens show a high concentration of pills in a general line not parallel to either fabric direction, assume a specimen is wedged around the impeller see Note 8 for one or more periods during the test.

Always use the astmm weight and plane angle. These factors are not evaluated when pilling is rated solely on the number of pills. To cope with this problem in the laboratory, make a subsequent test using the used liner surface on which the silicone-treated fabric was tested with a standard in-house fabric of known pilling history.

Each test facility must decide on an appropriate fabric.

Repeat, holding an adjacent corner. Since the overall acceptability of a speci? The side against the chamber may or may not have been used. A number in parentheses indicates the year of last reapproval.

Other materials with established test values may be used for this purpose. The pilling resistance of a speci? The pilling resistance of a specific fabric in actual wear varies more with general conditions of use and individual wearers than in replicate fabric specimens subjected to controlled laboratory tests. The observed resistance to pilling is reported on an arbitrary scale ranging from 5 no pilling to 1 very severe pilling.

Hang the specimens on racks until dry, and in any case for at least 2 h. NOTE 3—Full-strength adhesive or any dilution down to 1 part adhesive with 1 part water may be used see 7.
