Summary of Tes

11、t Method4.1 Pilling and other changes in surface appearance, such asfuzzing, that occur in normal wear are simulated on a labora-tory testing machine. Pills are caused to form on fabric by arandom rubbing action produced by tumbling specimens in acylindrical test chamber lined with a mildly abrasive

12、 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 specimens with visual standards that

13、 may be actualfabrics, or photographs of fabrics, showing a range of pillingresistance. The observed resistance to pilling is reported usingan arbitrary rating scale.1This test method is under the jurisdiction of ASTM Committee D13 on Textilesand is the direct responsibility of Subcommittee D13.60 o

16、s.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 acceptance testing, it should be used withcaution because the between-laboratory precision is poor. Insome cases the purchaser and the su

17、pplier 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-tween reported test results for two laboratories (or more)

18、,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 fromwhich the disparate test results were obtained, and ran

19、domlyassigned 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 testing series. I

20、f 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 which may include typeof fiber or blends, fiber dimensions, yar

21、n 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 fabric specimens subjected to con

22、trolled 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 evaluated when pilling is rated sol

23、ely 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 pills and the other factors affect

24、ing 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 thefabric type being tested, may be set

25、 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 respect totheir size and contrast,

26、 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, which may beactual fabrics or photographs of fabrics, show

27、ing 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 as aresult of variations in fib

Hang thespecimens on racks until dry, and in any case for at least 2 h.NOTE 3Full-strength adhesive or any dilution down to 1 part adhesivewith 1 part water may be used

44、(see 7.1). Pressing the adhesive into thespecimen face may be accomplished using the dispensing nozzle in aclosed configuration. The rounded end of a glass stirring rod works well,also, but caution should be used to prevent breakage and possible injuryfrom broken glass.10. Preparation of Apparatus10
