The results obtainedfrom the use of this instrument assist in evaluating these factorsrelative to the wear servic

17、eability of the final textile product inspecific end uses. The resistance to abrasion 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

18、added to the fibers, yarns or fabric; the nature of theabradant; the tension on the 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

19、 of fabrics, agreed with those obtained based uponperformance in end use. However, caution 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 fu

20、rther understand the complex behavior that mayoccur as a result of abrasion that may 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 asc

21、ertain the effect ofchanges in a fabrics resistance to abrasion when it becomeswet. 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

22、 used as a guide in evaluating textiles inquality control and in research.5.3.1 If there 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 compet

23、ent statisticalassistance. As a minimum, the test samples should be used thatare as 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 establishe

24、d test valuesmay be used for this purpose. The test results from the twolaboratories 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 a

25、djusted in consider-ation of the known bias.5.4 This test is unique and is significantly 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 specifie

26、d test conditionsmay be performed on a series of specimens, which are thensubjected 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.

27、 Whilethe “abrasion resistance” stated in terms of the number ofcycles and “durability” (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 nece

28、ssary inany calculation of predicted durability from specific abrasiondata.5.6.1 Laboratory 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 per

29、formance duringactual wear life for specific end uses unless there are datashowing the 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 applicati

30、on.Whenever possible all materials that are to be compared witheach other should be 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 r

31、esistanceis not directly proportional to the change in the fabric mass.5.9 All the guides 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 method

32、s most widely usedin the industry. Because there is a definite need for measuringthe 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

33、Abrasion Tester8, shown in Figs. 1 and 2,consists of an abrading mechanism, specimen 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 th

34、e same direction at very nearly but notquite the same angular velocity (250 rpm) on noncoaxial axeswhich are parallel to within 0.0025 mm (0.0001 in.).4Schiefer, H. F. and Krasny, J.

38、on. Each rotation is equivalent to onecycle.6.1.2 The abrading mechanism consists of 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 a

39、bradant, shaft, and weights. Acounterweight for balancing the abradant and abradant 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

40、tolerances are 61%.6.1.3 The specimen-supporting mechanism provides fortension mounting 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,or2in.) in diameter, as prescribed, shall be mounted

41、 at the upperend of the specimen shaft to fix the area of the specimen to beabraded. 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

42、the seat (C, Fig. 3) and canbe fastened to it by merely rotating it slightly to 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 l

43、owered by turning the cam,the combined mass of the clamp seat and specimen clamp 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 chang

44、ing the mass of the clampseat, for example, by adding auxiliary weights as in 6.1.2.1. 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 specime

46、sitive microswitch (H, Fig. 2) to stop the machineautomatically when a tension-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 aprogramm

47、able counter that will stop the instrument uponreaching a preset number of rotations.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.

48、3), which is essentiallyconstant in its action for a long period of use, shall 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 subj

49、ect to variations due tochanges in the abradant during specific tests. The spring 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
