9、her 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 controlled rubbingagainst an elastomeric pad having specifically selected me-chanical properties. The degr

The observed resistance to pilling isreported using an arbitrary rating scale.5. Significance and Use5.1 Acceptance
11、 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 data are not available. In somecases the purchaser and the supplier may have to test acommercial shipm

Competent statistical assis-tance is recommended for the investigation of bias.Aminimumof two parties should take a group of test specimens which areas
17、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 laboratoriesshould be compared using an acceptable statistical protocol andpro
18、bability 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 and corrected, orthe purchaser and the supplier must agree to interpre
19、t 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 fabric construc-tion, and fabric finishing treatments. The pilling resis
20、tance 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 adopting levels ofacceptability for any series of standards.5.3 Finish
21、es 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 interestedparties should determine the state of test.5.4 Pills vary appreciabl
22、y 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 surface phenomena such as loss of cover, colorchange, or the development o
23、f 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 evaluated subjectively with regard to their acceptability andnot rated solel
24、y 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 advantageouswhen the laboratory test specimens correlate closely in appear-ance
25、 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 excessive timerequired for counting, sizing, and calculation.5.5 The degree
26、 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 an arbitrary scale ranging from 5 (no pilling) to 1 (verysevere pilling
27、).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 non-wovenfabrics has not been determined.6. Apparatus and Materials6.1 S

44、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 manner that no two specimenscontain the same yarns. Avoid areas with wrinkles and otherdis
45、tortions. 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 fabric specimen flat against the friction pad during thetest. Do this by rubbing the base
46、 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 thereafter fromthe specimen holder because this will disturb the alignment.Retain an additi
47、onal 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 under a5N(1lbf) force against a mountedpolyester/cotton twill fabric (see 6.3). Continue this
48、 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
49、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 withsuitable solvent (see 6.7), then any household detergent/watersolution, rinsing with cle
