Pills are caused to form on fabric by arandom rubbing action produced by tumbling specimens in acylindrical test c
11、hamber lined with a mildly abrasive material.To form pills with appearance and structure that resemble thoseproduced in actual wear, small amounts of short-length graycotton fiber are added to each test chamber with the specimens.The degree of fabric pilling is evaluated by comparison of thetested s

Significance and Use5.1 Acceptance TestingThis method of testing fabrics forresistance to pilling is not recommended for acceptance testing.If it is used for acceptance testing, it should be used withcaution because the between-laborato
16、ry precision is poor. Insome cases the purchaser and the supplier may have to test acommercial shipment of one or more specific materials by thebest available test method, even though the test method is notrecommended for acceptance testing.5.1.1 If there are differences or practical significance be
17、-tween reported test results for two laboratories (or more),comparative tests should be performed to determine if there isa statistical bias between them, using competent statisticalassistance. As a minimum, the test samples should be used thatare as homogeneous as possible, drawn from the material
18、fromwhich the disparate test results were obtained, and randomlyassigned in equal numbers to each laboratory for testing. Othermaterials with established test values may be used for thispurpose. The test results from the two laboratories should becompared using a statistical test for unpaired data,
19、at aprobability level chosen prior to the testing series. If a bias isfound, either its cause must be found and corrected, or futuretest results must be adjusted in consideration of the knownbias.5.2 The pilling of textile fabrics is a very complex propertybecause it is affected by many factors whic
20、h may include typeof fiber or blends, fiber dimensions, yarn and fabricconstruction, fabric finishing treatments and refurbishingmethod. Testing before refurbishing may be adviseable. Thepilling resistance of a specific fabric in actual wear varies morewith general conditions of use and individual w
21、earers than inreplicate fabric specimens subjected to controlled laboratorytests. This experience should be borne in mind when adoptinglevels of acceptability for any series of standards.5.3 Pills vary appreciably in size and appearance anddepend on the presence of lint and degree of color contrast.
22、These factors are not evaluated when pilling is rated solely onthe number of pills. The development of pills may be accom-panied by other surface phenomena such as loss of cover, colorchange, or the development of fuzz. Since the overall accept-ability of a specific fabric is dependent on both the c
23、haracter-istics of the pills and the other factors affecting surfaceappearance, it is suggested that fabrics tested in the laboratorybe evaluated subjectively with regard to their acceptability andnot rated solely on the number of pills developed. A series ofstandards, based on graduated degrees of
24、surface change of thefabric type being tested, may be set up to provide a basis forsubjective ratings. The visual standards are most advantageouswhen the laboratory test specimens correlate closely in appear-ance with worn fabrics and show a similar ratio of pills to fuzz.Counting the pills and weig
25、hing their number with respect totheir size and contrast, as a combined measure of pillingresistance, is not recommended because of the excessive timerequired for counting, sizing, and calculating.5.4 The degree of fabric pilling is evaluated by comparingthe tested specimens with visual standards, w
26、hich may beactual fabrics or photographs of fabrics, showing a range ofpilling resistance. The observed resistance to pilling is reportedon an arbitrary scale ranging from 5 (no pilling) to 1 (verysevere pilling).5.5 This test method is applicable to a wide variety ofwoven and knitted fabrics that v
