Terminology3.1 For definitions of textile terms used in this specification refer to Terminologies D123 and D7022. For terms relating tochemical and colorfastness testing refer to specific AATCC t
16、est methods.3.2 Definitions found in a dictionary of common usage are suitable for this specification.4. Significance and Use4.1 Fabrics intended for this end-use should meet all of the requirements listed in Table 1.4.2 It should be recognized that fabric can be produced utilizing an almost infinit
17、e number of combinations of constructionvariables (e.g., type of fibers, percentage of fibers, yarn twist, yarn number, warp and pick count, chemical and mechanicalfinishes).Additionally, fashion or aesthetics dictate that the ultimate consumer may find acceptable articles made from fabrics thatdo n
18、ot conform to all of the requirements in Table 1.4.2.1 Hence, no single performance specification can possibly apply to all the various fabrics that could be utilized for thisend-use.4.3 The uses and significance of particular properties and test methods are discussed in the appropriate sections of
19、the specifiedtest methods.5. Test Methods (see Note 1)5.1 Breaking Strength (woven fabrics only)Determine the dry-breaking strength as directed in the grab test procedure of TestMethod D5034 using a constant-rate-of-extension (CRE) tensile testing machine.TABLE 1 Specification RequirementsCharacteri

These methods cannot be usedinterchangeably since there may be no overall correlation between them (see Note 2, Note 3, Note 4, and Note 56).BSee Note 5.D7019 142NOTE 2If preferred a constant-rate-of-traverse (CRT) tensile testing machine may be use
25、d. There may be no overall correlation between the resultsobtained with the CRT machine and the CRE machine. Consequently, these two testers cannot be used interchangeably. In case of controversy, the CREmethod, Test Method D5034, shall prevail.5.2 Tearing Resistance (woven fabrics only)Determine th
26、e tear resistance as directed in Test Method D1424.NOTE 3If preferred, use of the tensile testing machine is permitted as directed in Test Method D2261. There may be no overall correlation betweenthe results obtained with the Elmendorf machine (Test Method D1424) and with the tongue tear machines (T
27、est Method D2261). Consequently, these twotesters cannot be used interchangeably. In case of controversy, Test Method D1424 shall prevail.5.3 Resistance to Yarn Slippage (woven fabrics only)Determine the resistance to yarn slippage as directed in Test MethodD434.5.4 Yarn Distortion (woven fabrics on

Since there is no ov
29、erall correlation between the resultsobtained with the CRE machine equipped with a bursting attachment (Test Method D3787) and the diaphragm bursting tester Test Method D3786), thesetwo bursting testers cannot be used interchangeably. In case of controversy, the diaphragm bursting tester machine (Te
30、st Method D3786) shall prevail.5.6 Dimensional Change:5.6.1 LaunderingDetermine the dimensional change after laundering as directed in the applicable procedure in AATCCMethod 135.5.6.2 DrycleaningDetermine the dimensional change after drycleaning as directed in AATCC Test Method 158.5.7 Colorfastnes
31、s:5.7.1 LaunderingDetermine the colorfastness to laundering as directed in the applicable procedure of AATCC Method 61.NOTE 5It has been reported that the results for staining, obtained by standard AATCC Test Methods, on fabrics dyed to dark shades that contain acombination of polyester and spandex,
32、 or their blends, may not show the full staining propensity of such fabrics in consumer use. It is, therefore,recommended that the staining results obtained by these tests not be used for acceptance testing of such fabrics.5.7.2 DrycleaningDetermine the colorfastness to drycleaning as directed in AA
33、TCC Test Method 132.NOTE 6Launderable fabrics are expected normally to be drycleaned, except where all or part of the fabric will not withstand drycleaning. Forexample, the fabric could contain a functional finish soluble in the solvent, or the fiber could be degraded by the solvent, which would be
34、the case withpoly (vinyl chloride) fiber. If a fabric would be harmed by ALL methods of care except for drycleaning, it should be considered Dryclean only.5.7.3 BleachingWhen testing with bleach is indicated, test as directed in AATCC Test Method 172 for sodium hypochloritebleach, or AATCC Test Meth

37、see Note 6).5.7.7 LightDetermine colorfastness to light as directed in AATCC Method 16.NOTE 7There are distinct differences in spectral distribution between the various types of machines listed in AATCC Method 16, with no overallcorrelations between them. Consequently, these machines cannot be used
38、interchangeably. In case of controversy, results obtained with the water-cooledxenon-arc machine listed in Option E shall prevail.5.8 Fabric AppearanceDetermine the fabric smoothness appearance (SA) as directed in AATCC Method 124 after theapplicable laundering or dry cleaning procedure.5.8.1 For fa
39、brics not intended for use in durable press garments, determine the smoothness appearance after pressing as specifiedin 10.2.5 of AATCC Test Method 135.5.9 FlammabilityThe flammability test and requirements shall meet or exceed the Flammable Fabrics Act mandatorystandards as specified in 16 CFR 1610
