10、Use5.1 Fabrics intended for this end-use should meet all of therequirements listed in Table 1.5.2 It should be recognized that fabrics can be producedwith an almost infinite number of combinations of constructionvariables (for example, type of fibers, percentage of fibers, yarntwist, yarn number, wa

11、rp and pick count, chemical andmechanical finished.) Additionally, fashion or aesthetics dictatethat the ultimate consumer may find acceptable articles madefrom fabrics that do not conform to all of the requirements inTable 1.5.2.1 Hence, no single performance specification can possi-bly apply to al

12、l the various fabrics that could be utilized for thisend-use.5.3 The uses and significance of particular properties andtest methods are discussed in the appropriate sections of thespecified test methods.5.4 The significance and use of particular properties and testmethods are discussed in the approp
