The valuesstated in each system are not exact equivalents; therefore, eachsystem shall be used independently o
5、f the other. Combiningvalues from the two systems may result in nonconformancewith the specification.1.3 This standard does not purport to address all of thesafety concerns, if any, associated with its use.

Summary of Test Method4.1 Pilling and other changes in surface appearance, such asfuzzing, which occur in normal wear are simulated on labora-tory testing machines. Fabrics are subjected to simulated wearconditions: first brushing
10、the specimens to free fiber ends thatform fuzz on the surface of the fabric, then rubbing two of thespecimens together in circular motion to roll the fiber ends intopills. The degree of fabric pilling is evaluated by comparing thetested specimens with visual standards, which may be actualfabrics or
11、photographs of fabrics, showing a range of pillingresistance. The observed resistance to pilling is reported usingan arbitrary rating scale.5. Significance and Use5.1 Acceptance TestingThis method of testing fabrics forresistance to pilling is not recommended for acceptance testing.If it is used for
12、 acceptance testing, it should be used withcaution because interlaboratory data are not available. In somecases the purchaser and the supplier may have to test acommercial shipment of one or more specific materials by thebest available method, even though the method has not beenrecommended for accep
13、tance testing.5.1.1 If there are differences or practical significance be-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 sh
14、ould be used thatare as homogeneous as possible, drawn from the material from1This test method is under the jurisdiction of ASTM Committee D13 on Textilesand is the direct responsibility of Subcommittee D13.60 on Fabric Test Methods,Specific.Current edition approved July 1, 2008.

17、 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, at aprobability level chosen prior to the testing series. If a bias isfound, either its caus
18、e must be found and corrected, or futuretest results for that material must be adjusted in considerationof the known bias.5.2 The pilling of textile fabrics is a very complex propertybecause it is affected by many factors which may include typeof fiber or blends, fiber dimensions, yarn and fabric co
19、nstruc-tion, fabric finishing treatments and refurbishing method.Testing before refurbishing may be adviseable. The pillingresistance of a specific fabric in actual wear varies more withgeneral conditions of use and individual wearers than inreplicate fabric specimens subjected to controlled laborat
20、orytests. 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.These factors are not evaluated when pilling is rated solely onthe numbe
21、r 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 character-istics of the pills and the other factors affecting surfaceappe
22、arance, 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 surface change of thefabric type being tested, may be set up to provide
23、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 weighing their number with respect totheir size and contrast, as a combined
24、measure of pillingresistance, is not recommended because of the excessive timerequired for counting, sizing, and calculation.5.4 The degree of fabric pilling is evaluated by comparingthe tested specimens with visual standards, which may beactual fabrics or photographs of fabrics, showing a range ofp
25、illing 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 vary in pilling propensity as aresult of variations in fiber, yarn eight

42、intenance Checks:10.1.1 Check the operation of the pilling tester with one ormore standard in-house fabrics of known pilling resistance asdirected as follows:10.1.1.1 If the tester is in daily use, check the tester usingthe standard fabric(s) at least once a week.10.1.1.2 If testing is done infreque
43、ntly, check the testerusing the standard fabric(s) each time it is used.10.1.2 If the tester is used daily, clean the brushes with asuitable solvent such as acetone (see 6.1), remove any lint witha hand card, and clip any protruding bristles at least once aweek. If testing is done infrequently, chec

Procedure12.1 Make all tests in the standard atmosphere for testingtextiles.12.2 Place the brush board on the 19.0-mm (0.75-in.) radiusrotating platform with the bristles poi

48、he test time intervals used should reproduce the appearanceof actual wear as seen in garments made from the specific type of fabricunder test. The test time intervals for brushing and pilling specified in 12.4and 12.5 have been found satisfactory for most clear-finish suitings,lightweight shirtings,
