Summary of Test Method4.1 Pilling and other changes in surface appearance thatoccur in normal wear are simulated on a laboratory testingmachine. Fabric samples are washed or drycleaned, dependingon expected refurbishment, followed by cont

10、rolled rubbingagainst an elastomeric pad having specifically selected me-chanical properties. The degree of fabric pilling is evaluated bycomparison of the tested specimens with visual standards thatmay be actual fabrics, or photographs of fabrics, showing arange of pilling resistance. The observed

11、resistance to pilling isreported using an arbitrary rating scale.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 interlaboratory

12、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.1This test method is under the jurisdiction of ASTM Committee

16、tatistical bias,if any, between the laboratory of the purchaser and thelaboratory of the supplier should be determined based ontesting 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.Ami

17、nimumof two parties should take a group of test specimens which areas homogeneous as possible and which are from a lot ofmaterial of the type in question. The test specimens should thenbe randomly assigned in equal numbers to each laboratory fortesting. The average test results from the two laborato

18、riesshould be compared using an acceptable statistical protocol andprobability level chosen by the two parties before the testingbegins. 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

19、and corrected, orthe purchaser and the supplier must agree to interpret futuretest results with consideration for 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 or blends, fiber dimensions, yarn and fa

20、bric construc-tion, and fabric finishing treatments. The pilling resistance of aspecific fabric in actual wear varies more with general condi-tions of use and individual wearers than in replicate fabricspecimens subjected to controlled laboratory tests. This expe-rience should be borne in mind when

21、adopting levels ofacceptability for any series of standards.5.3 Finishes and fabric surface changes may exert a largeeffect on pilling. It is recommended that fabrics be tested afterlaundering or drycleaning, or both. Testing before refurbishingmay also be advisable. Prior agreement between interest

22、edparties should determine the state of test.5.4 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 solely onthe number of pills. The development of pills may be accom-panied by other surf

23、ace 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 affecting surfaceappearance, it is suggested that fabrics tested in the laboratorybe evalua

24、ted 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 up to provide a basis forsubjective ratings. The visual standards are most advantage

25、ouswhen 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 weighting their number with respect totheir size and contrast, as a combined measure of pillingresistance, is not recommended because of the exces

26、sive timerequired for counting, sizing, and calculation.5.5 The degree of fabric pilling is evaluated by comparingthe tested specimens with visual standards, which may beactual fabrics or photographs of fabrics, showing a range ofpilling resistance. The observed resistance to pilling is reportedon a

27、n arbitrary scale ranging from 5 (no pilling) to 1 (verysevere pilling).5.6 This test method is applicable to a wide variety ofwoven and knitted fabrics that vary in pilling propensity as aresult of variations in fiber, yarn and fabric structure, andfinish. The applicability of the test method to no

Sampling8.1 Primary Sampling UnitConsider rolls of fabric orfabric components of fabricated systems to be the primarysampling unit, as appl

38、icable.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 withi

39、n a 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 is1m(1yd)in length along the selvage (machine direction),

40、after firstremoving a 1 m (1 yd) length. For fabric components offabricated systems use the entire system.8.2.1 For acceptance testing of garments, take one garmentfrom each carton (see Note 2).9. Test Specimens: Selection, Number, and Preparation9.1 Unless otherwise specified, samples should be was

Takethe specimens evenly spaced across the width of the laboratorysample, or from three different panels in a garment. Specimensshould be staggered in such

45、a manner 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 t

46、he 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

47、 thereafter 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 u

48、nder a5N(1lbf) 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. A

49、ccomplish 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 InstrumentPerformancePeriodically run a standard in-house test fabricof known pilling rating to check the reproducibility of theresult being obtained with a given pad.NOTE 3If the bushing in the rotating base is worn, vibration mayproduce erratic test results.10.3.1 In the event that finishing agents have impregnated apad, it may be possible to remove them by rubbing w
