Abrasion resistancefor wear is evaluated by one or more conditions of destruction,a defined surface damage, loss in the ma

17、ss, strength orthickness of test specimens, or by increased weakness in thesample as shown by a subsequent test by another method,depending on the material or its intended use.5. Significance and Use5.1 The resistance to abrasion of textile materials is affectedby many factors in a complex manner. T

18、he 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 abrasion is affected bymany factors that include the inherent mechanical properties ofthe fibers; the dimension

19、s 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 specimen; the pressure between thespecimen and the abradant; and the dimensional changes in thespecimen.

20、 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, caution is advised becauseanomalous results may occur due to uncontrolled factors inmanufacturing or othe

21、r processes. Specific instances have beendescribed.5,6,7,8In any event, anomalous results should bestudied to further 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” conditi

22、ons 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. This test can also increase the uniformity of the abradingaction by washing away abrasion debris and pre

23、venting 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 there are differences of practical significance be-tween reported test results for two laboratories (or m

24、ore),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 homogenous as possible, that are drawn from thematerial from which the disparate test results were obtai

25、ned,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 should be compared using a statistical test forunpaired data, at a probability level chosen prior to th

26、e 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 significantly different from anyother existing abrading test.5.5 This test method may also be used as a technique

27、 forpretreating material for subsequent testing. For example, apredetermined number of abrasion cycles at specified testconditions may be performed on a series of specimens, whichare then subjected to a strength or barrier performance test.5.6 The resistance of textile materials to abrasion as mea-s

28、ured 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 “durability” (defined as the ability to withstanddeterioration or wearing out in use, including the effects ofa

29、brasion) 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 Laboratory tests may be reliable as an indication ofrelative end-use suitability in cases where the diffe

30、rence 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 the specific relationship between laboratory abrasiontests and actual wear in the intended end use.5.7

31、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 tested under the same pressure andtension.5.8 When abrasion tests are continued to total destruction,a

32、brasion 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 test methods and instruments that have beendeveloped for abrasion resistance may show a high degree ofv

33、ariability in results obtained by different operators and indifferent laboratories; however, they represent the methodsmost widely used in the industry. Because there is a definiteneed for measuring the relative resistance to abrasion, this isone of the several standardized guides and methods that i

34、suseful to help minimize the inherent variation in results thatmay occur.6.

The abradant andspecimen rotate in the same direction at very nearly but notquite the same angular velocity (250 rpm

39、) on noncoaxial axeswhich are parallel to within 0.0025 mm (0.0001 in.).6.1.1 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

40、 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

41、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

42、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

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

44、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

45、 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.

46、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

47、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-

48、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

Aspring steel blade abradant (B, Fig. 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 subject to variations due tochanges in the abradant du
