1、Designation: D 3512 07Standard Test Method forPilling Resistance and Other Related Surface Changes ofTextile Fabrics: Random Tumble Pilling Tester1This standard is issued under the fixed designation D 3512; the number immediately following the designation indicates the year oforiginal adoption or, i
2、n the case of revision, the year of last revision. A number in parentheses indicates the year of last reapproval. Asuperscript epsilon (e) indicates an editorial change since the last revision or reapproval.1. Scope1.1 This test method covers the resistance to the formationof pills and other related
3、 surface changes on textile fabricsusing the random tumble pilling tester. The procedure isgenerally applicable to all types of woven and knitted apparelfabrics.NOTE 1For other test methods for the pilling resistance of textiles,refer to Test Methods D 3511, D 3514, and D 4970.1.2 Some fabrics that
4、have been treated with a silicone resinmay not be satisfactorily tested by this procedure because thesilicone resin may transfer onto the cork liners in the testchamber and cause erroneous results.1.3 The values stated in either SI units or inch-pound unitsare to be regarded separately as the standa
5、rd. Within the text,the inch-pound units are to be regarded as the standard. Withinthe text, the inch-pound units are shown in parentheses. Thevalues stated in each system are not exact equivalents; there-fore, each system shall be used independently of the other.Combining values from the two system
6、s may result in noncon-formance with the specification.1.4 This standard does not purport to address all of thesafety concerns, if any, associated with its use. It is theresponsibility of the user of this standard to establish appro-priate safety and health practices and determine the applica-bility

Summary of Test 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 fa
11、bric by arandom rubbing action produced by tumbling specimens in acylindrical test chamber lined with a mildly abrasive 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
12、the specimens.The degree of fabric pilling is evaluated by comparison of thetested specimens with visual standards that may be actualfabrics, or photographs of fabrics, showing a range of pillingresistance. The observed resistance to pilling is reported usingan arbitrary rating scale.5. Significance
13、 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.

17、the supplier 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
18、 more),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, a
19、nd 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 testing ser
20、ies. If 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 dimension
21、s, 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 fabric specimens subjected
22、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 evaluated when pilling is rat
23、ed 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 pills and the other factors
24、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 thefabric type being tested, may
25、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 respect totheir size and con
26、trast, 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
27、, 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 as aresult of variations

Hazardous Materials7.1 Adhesives used in this test method may be hazardous.Refer to the manufacturers material safety data sheets forinformation on use, handling, storage, and disposal of theseproducts.8. Sampling8.1 Primary Sampling UnitConsider rolls of fabric orfabric co
37、mponents of fabricated systems to be the primarysampling unit, as applicable.NOTE 2An adequate specification or other agreement between thepurchaser and the supplier requires taking into account the variabilityamong rolls, bolts, or pieces of fabric and among specimens from a swatchof fabric from a
38、roll, bolt, or piece, or between cartons of garments andamong garments within 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 pie
39、ce of fabric that is1m(1yd)in length along the selvage (machine direction), 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,
40、Number, and Preparation9.1 Samples may be washed or dry cleaned before cuttingthe test specimens, using conditions appropriate for the fabricend use or conditions agreed upon by all interested parties.9.2 Cut specimens in squares 105 mm (4.13 in.) on the biasat an approximate 0.78 rad (45) angle to
41、the warp (wale) andfilling (course) directions.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 manner that no two specimenscontain the sa
42、me yarns. Avoid areas with wrinkles and otherdistortions. Unless otherwise specified, do not cut specimensnearer the selvage than one tenth the width of the fabric.9.3 Mark replicate specimens in one corner on the face ofthe fabric with the appropriate number 1, 2, or 3.9.4 If loosely woven specimen
43、s fray when applying identi-fication markings, cut the specimens with sides parallel to thewarp and filling and ravel the sides no more than 5 mm (0.2 in.)on each side, leaving the fringe.9.5 Seal the edges of all specimens to a width not exceeding3 mm (.13 in.) on the face of the fabric with adhesi
44、ve. 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 (see 7.1). Pressing the adhesive into thespecimen face may be accomplished using the dispensing nozzle in aclosed configuration
45、. The rounded end of a glass stirring rod works well,also, but caution should be used to prevent breakage and possible injuryfrom broken glass.NOTE 4Although the use of glued or not glued specimens is accept-able, the measurements should not be compared.10. Preparation of Apparatus10.1 Fit a cork li
46、ner snugly around the inside of a cleanedtest chamber with an unused cork surface facing the rotorblades. The side against the chamber may or may not have beenused. To eliminate any tendency for the liner to rotate, tape theoutside edge of the liner to the chamber wall at the butt jointwith a short
47、piece of 25-mm (1-in.) wide masking tape.10.1.1 Discard cork liners that have been used for1honeach surface.10.2 After every hour of machine running time, remove theliner and clean the impeller by wiping with a cloth wetted in asolution of detergent and water. Allow the chamber to drybefore the next
48、 use.5Cotton dyed to a medium gray shade before carding using a colorfast reactiveblack dye and standard reactive dyeing procedure.
