Significance and

16、Use5.1 The resistance to abrasion of textile materials is affectedby many factors in a complex manner. The results obtainedfrom the use of this instrument assist in evaluating these factorsrelative to the wear serviceability of the final textile product inspecific end uses. The resistance to abrasio

17、n is affected bymany factors that include the inherent mechanical properties ofthe fibers; the dimensions of the fibers; the structure of theyarns; the construction of the fabrics; the type, kind, amount oftreatment added to the fibers, yarns or fabric; the nature of theabradant; the tension on the

18、specimen; the pressure between thespecimen and the abradant; and the dimensional changes in thespecimen. Experience has shown in many instances, thatrelative results obtained with this instrument when used on aseries of fabrics, agreed with those obtained based uponperformance in end use. However, c

19、aution is advised becauseanomalous results may occur due to uncontrolled factors inmanufacturing or other processes. Specific instances have beendescribed.4,5,6,7In any event, anomalous results should bestudied to further understand the complex behavior that mayoccur as a result of abrasion that may

20、 in turn assist in thedevelopment of more durable fabrics.5.2 Testing some specimens under “wet” conditions can addanother dimension to the evaluation of some textiles. Suchtesting under “wet” conditions can help ascertain the effect ofchanges in a fabrics resistance to abrasion when it becomeswet.

21、This test can also increase the uniformity of the abradingaction by washing away abrasion debris and preventing thebuild up of broken fibers that can interfere with the properprogression of the tests.5.3 This test is used as a guide in evaluating textiles inquality control and in research.5.3.1 If t

22、here are differences of practical significance be-tween reported test results for two laboratories (or 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

23、homogenous as possible, that are drawn from thematerial from which the disparate test results were obtained,and that are randomly assigned in equal numbers to eachlaboratory for testing. Other fabrics with established test valuesmay be used for this purpose. The test results from the twolaboratories

24、 should be compared using a statistical test forunpaired data, at a probability level chosen prior to the testingseries. If a bias is found, either a cause must be found andcorrected, or future test results must be adjusted in consider-ation of the known bias.5.4 This test is unique and is significa

25、ntly different from anyother existing abrading test.5.5 This guide may also be used as a technique for pretreat-ing material for subsequent testing. For example, a predeter-mined number of abrasion cycles at specified test conditionsmay be performed on a series of specimens, which are thensubjected

26、to a strength or barrier performance test.5.6 The resistance of textile materials to abrasion as mea-sured by this guide does not include all the factors whichaccount for wear performance or durability in actual use. Whilethe “abrasion resistance” stated in terms of the number ofcycles and “durabili

27、ty” (defined as the ability to withstanddeterioration or wearing out in use, including the effects ofabrasion) are frequently related. The relationship varies withdifferent end uses, and different factors may be necessary inany calculation of predicted durability from specific abrasiondata.5.6.1 Lab

28、oratory tests may be reliable as an indication ofrelative end-use suitability in cases where the difference inabrasion resistance of various materials is large, but theyshould not be relied upon for prediction of performance duringactual wear life for specific end uses unless there are datashowing t

29、he specific relationship between laboratory abrasiontests and actual wear in the intended end use.5.7 The pressure and tension used is varied, depending onthe mass and nature of the material and the end use application.Whenever possible all materials that are to be compared witheach other should be

30、tested under the same pressure andtension.5.8 When abrasion tests are continued to total destruction,abrasion resistance comparisons are not practical for fabricshave a different mass because the change in abrasion resistanceis not directly proportional to the change in the fabric mass.5.9 All the g

31、uides and instruments that have been developedfor abrasion resistance may show a high degree of variability inresults obtained by different operators and in different labora-tories; however, they represent the methods most widely usedin the industry. Because there is a definite need for measuringthe

32、 relative resistance to abrasion, this is one of the severalstandardized guides and methods that is useful to help mini-mize the inherent variation in results that may occur.6. Apparatus and Materials6.1 The Uniform Abrasion Tester8, shown in Figs. 1 and 2,consists of an abrading mechanism, specimen

33、 supportingmechanism, and driving mechanism. Essentially, the surface ofthe abradant lies in a plane parallel to the surface supportingthe specimen and presses upon the specimen. The abradant andspecimen rotate in the same direction at very nearly but notquite the same angular velocity (250 rpm) on

34、noncoaxial axeswhich are parallel to within 0.0025 mm (0.0001 in.).4Schiefer, H. F. and Krasny, J.

37、2.8Apparatus and accessories are commercially available.D4158 08 (2012)26.1.1 The small difference in speed is to permit each part ofthe specimen to come in contact with a different part of theabradant at each rotation. Each rotation is equivalent to onecycle.6.1.2 The abrading mechanism consists of

38、 the abradantmounted at the lower end of a shaft, weights placed on theupper end of the shaft to produce constant pressure betweenabradant and specimen throughout the test, lever and cam forraising and lowering the abradant, shaft, and weights. Acounterweight for balancing the abradant and abradant

39、shaft isneeded when tests are to be carried out at low pressure.6.1.2.1 Weights, in increments of 500 g (1 lb) that arecapable of providing up to a total of 5 kg (10 lb) to thespecimen in pressure. Individual weight tolerances are 61%.6.1.3 The specimen-supporting mechanism provides fortension mount

40、ing of thinner, more flexible materials and rigidmounting of thick, stiff materials. For the first, a plasticpressure foot 12.5, 25, 31, 38, or 50 mm (12 ,1,114 ,112 ,or2 in.) in diameter, as prescribed, shall be mounted at the upperend of the specimen shaft to fix the area of the specimen to beabra

41、ded. A conical clamp seat, fitted to the shaft, rotates with itbut is free to move vertically on the shaft. A cam is providedfor raising and lowering the clamp seat. The specimen clampshown unassembled in Fig. 3 fits on the seat (C, Fig. 3) and canbe fastened to it by merely rotating it slightly to

42、engage the twopins in the slots. The clamp and specimen assembly can beremoved quickly for examining the specimen and measuringthe wear and returned to the machine without unclamping thespecimen. When the clamp seat is lowered by turning the cam,the combined mass of the clamp seat and specimen clamp

43、 issuspended by the specimen over the presser foot. This placesthe specimen under constant tension throughout the test withtake-up of any stretch in the specimen. Different tensions maybe applied to the specimen by changing the mass of the clampseat, for example, by adding auxiliary weights as in 6.

44、1.2.1. Forrigid mounting of thick, stiff fabrics such as carpeting andsome felts use the specimen clamp and mounting aids shown inFig. 4. Screw the assembly onto the specimen shaft in place ofthe presser foot and specimen clamp seat (E, Fig. 2).6.1.4 The driving mechanism consists of a motor-drivena

45、uxiliary drive shaft connected to the abradant shaft andspecimen shaft by spur gears.6.1.5 The instrument shall be equipped with ( 1) a counter(G, Fig. 2) resettable to indicate the number of rotations in atest; (2) a sensitive microswitch (H, Fig. 2) to stop the machineautomatically when a tension-

46、suspended specimen is wornthrough. A thickness gage (I, Fig. 2), when specified, isavailable to measure changes in thickness of the specimenduring the test.6.1.5.1 Alternately the instrument may be equipped with aprogrammable counter that will stop the instrument uponreaching a preset number of rota

47、tions.6.1.6 AbradantShall be sufficiently greater in diameterthan the specimen supporting the surface that the latter liesentirely inside the periphery of the abradant during a test. Aspring steel blade abradant (B, Fig. 3), which is essentiallyconstant in its action for a long period of use, shall

48、be used forwoven, felted, pile, and knitted fabrics and a cross-cut tungstentool steel blade abradant (A, Fig. 3) for coated fabrics, unlessotherwise specified in the material specification.6.1.6.1 Abrasion tests are subject to variations due tochanges in the abradant during specific tests. The spri

49、ng steelblade abradant and the cross-cut tungsten tool steel bladeabradant are considered permanent abradants that have ahardened metal surface. It is assumed that the abradant will notchange appreciably in a specific series of tests, but obviouslysimilar abradants used in different laboratories will not likelychange at the same rate due to differences in usage. Permanentabradants may also change due to pick-up of treatments orother material from test fabrics and must accordingly becleaned at frequent intervals. Consequently, depending upon itsusage, the abradant must
