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 wearco

10、nditions: 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 thetested specimens with visual standards, which

Significance and Use5.1 Acceptance TestingThis method of testing fabrics forresistance to pilling is not recommended for acceptance

As a minimum, the test samples should be used thatare as homogeneous as possible, drawn from the material fromwhich the disparate test results were obt

17、ained, 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, at aprobability level chosen prior to the tes

18、ting 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 many factors which may include typeof fiber

19、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 use and individual wearers than inreplicate f

20、abric 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.These factors are not eva

21、luated 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 character-istics of the pi

22、lls 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 surface change of thefabr

23、ic 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 weighing their number with re

24、spect 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 visual standards, which may beactual fabrics

25、 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 vary in pilling propensity
