Summary of Test Method4.1 Pilling and other changes in surface appearance thatoccur in normal wear are simulated on a laboratory testingmachine. Fabric sa

The degree of fabric pilling is evaluated bycomparison of the tested specimens with visual standards thatmay be actual fab

The observed resistance to pilling isreported using an arbitrary rating scale.1This test method is under the jurisdiction ofASTM Committee D13 on Textilesand is the direct responsibility of Subcommittee D13.60 on Fabric Test Meth

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 tes
16、ting, 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 acceptance testing.5
17、.1.1 If there is a disagreement arising from differences invalues reported by the purchaser and the supplier when usingTest Method D3514 for acceptance testing, the statistical bias,if any, between the laboratory of the purchaser and thelaboratory of the supplier should be determined based ontesting
18、 specimens randomly drawn from one sample of mate-rial of the type being evaluated. Competent statistical assis-tance is recommended for the investigation of bias.Aminimumof two parties should take a group of test specimens which areas homogeneous as possible and which are from a lot ofmaterial of t
19、he type in question. The test specimens should thenbe randomly assigned in equal numbers to each laboratory fortesting. The average test results from the two laboratoriesshould be compared using an acceptable statistical protocol andprobability level chosen by the two parties before the testingbegin
20、s. Appropriate statistical disciplines for comparing datamust be used when the purchaser and supplier cannot agree. Ifa bias is found, either its cause must be found and corrected, orthe purchaser and the supplier must agree to interpret futuretest results with consideration for the known bias.5.2 T
21、he 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 fabricconstruction, and fabric finishing treatments. The pilling resis-tance of a specific fabric in actual wear varies more withgeneral
22、 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 Finishes and fabric surface changes may exert a largeeffect on pilling. It
23、 is recommended that fabrics be tested afterlaundering or drycleaning, or both. Testing before refurbishingmay also be advisable. Prior agreement between interestedparties should determine the state of test.5.4 Pills vary appreciably in size and appearance anddepend on the presence of lint and degre
24、e 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 dep
25、endent 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 g
26、raduated 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.Countin
27、g the pills and weighting 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.5.5 The degree of fabric pilling is evaluated by comparingthe tested specimens wit
28、h 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).5.6 This test method is applicable to a wide variety ofwoven and k
29、nitted fabrics that vary in pilling propensity as aresult of variations in fiber, yarn and fabric structure, andfinish. The applicability of the test method to non-wovenfabrics has not been determined.6. Apparatus and Materials6.1 Stoll Quartermaster Universal Wear Tester, with frost-ing attachment.

Sampling8.1 Primary Sampling UnitConsider rolls of fabric orfabric components of fabricated systems to be the primarysampling unit, as applicab
39、le.NOTE 2An adequate specification or other agreement between pur-chaser and supplier requires taking into account the variability amongrolls, bolts, or pieces of fabric and among specimens from a swatch offabric from a roll, bolt, or piece, or among cartons of garments andbetween garments within a
40、carton, to provide a sampling plan with ameaningful producers risk, consumers risk, acceptable quality level, andlimiting quality level.8.2 Laboratory Sampling UnitFrom each primary sam-pling unit take one full-width piece of fabric that is1m1ydin length along the selvage (machine direction), after

For fabric components offabricated systems use the entire system.FIG. 1 Apparatus for Fabric EvaluationTABLE 1 Viewing Apparatus and OptionsApparatus Specimen PreparationASTM Lightbox (Fig. 1)A0.78 rad (45)LightboxB0.78 rad (45)LightboxBflatLightboxBcritical angleAs

Test Specimens: Selection, Number, and Preparation9.1
44、 Unless otherwise specified, samples should be washedor dry cleaned before cutting the test specimens, using condi-tions appropriate for the fabric end use or conditions agreedupon by all interested parties.9.2 Cut test specimens squares, 125 125 6 2.5 mm 5 56 0.1 in. with the sides parallel to the
45、warp (wale) and filling(course) directions, or circles, 100 6 2mm46 0.1 in. indiameter.9.2.1 Take three specimens from each laboratory unit. Takethe specimens evenly spaced across the width of the laboratorysample, or from three different panels in a garment. Specimensshould be staggered in such a m
46、anner that no two specimenscontain the same yarns. Avoid areas with wrinkles and otherdistortions. Unless otherwise specified, do not take specimensnearer the selvage than one tenth the width of the fabric.10. Preparation of Apparatus10.1 Level the specimen holder base pad properly to posi-tion the
47、fabric specimen flat against the friction pad during thetest. Do this by rubbing the base pad against a piece of 150-gritemery paper mounted snugly on the bottom side of the pressureplate.10.1.1 Once the base pad is properly prepared, it will last foran indefinite time. Do not remove the base pad th
48、ereafter fromthe specimen holder because this will disturb the alignment.Retain an additional specimen holder for use with other tests onthe Stoll tester.10.2 Preparation of Friction PadsBefore a new frictionpad is used for testing, prepare it by attaching it to the pressureplate and rubbing it unde
49、r a5N1lbf force against a mountedpolyester/cotton twill fabric (see 6.3). Continue this until thesurface shine in the rubbing area is completely and uniformlyremoved.10.2.1 Use the pad in the same position thereafter to alwayspresent a uniformly smooth surface to subsequently testedspecimens.Accomplish this by applying appropriate alignmentmarks to the pad and pressure plate. Always use the frictionpad with the same base pad with which it was prepared.10.3 Monitoring Repeatability of Instrument PerformancePeriodically run a standard in-hou
