The values stated ineach system may not be exact equivalent

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.
10、Fabrics are subjected to simulated wearconditions: first brushing 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 thetest
11、ed specimens with visual standards, which may be actualfabrics or 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 p

16、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 f
17、romwhich 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, a
18、t aprobability level chosen prior to the testing series. If a bias isfound, either its cause 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
19、many factors which may include typeof fiber or blends, fiber dimensions, yarn and fabric construc-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 u
20、se and individual wearers 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
21、 of color contrast.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 depe
22、ndent on both the character-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 gr
23、aduated degrees of 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
24、 the pills and weighing 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 calculation.5.4 The degree of fabric pilling is evaluated by comparingthe tested specimens with
25、visual standards, which 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 kni
