Summary of Test Method4.1 Pilling and other changes in surface appearance, such asfuzzing, which occur in normal wear
10、 are simulated on labora-tory testing machines. 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
11、fabric pilling is evaluated by comparing thetested 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 TestingT

As a minimum, the test samples should be used thatare
17、 as homogeneous as possible, drawn from the material 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 be
18、compared using a statistical test for unpaired data, at 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 fabric
19、s is a very complex propertybecause it is affected by 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
20、in actual wear varies more withgeneral conditions of use 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 a
21、ppearance anddepend on the presence of lint and degree 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 t
22、he overall accept-ability of a specific fabric is dependent 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
23、 of pills developed. A series ofstandards, based on graduated 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 fabr
24、ics 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 measure of pillingresistance, is not recommended because of the excessive timerequired for counting, sizing, and calculation.5.4 The degree of fabric pilli
