ASTM D7020-22

Standard Performance Specification for Woven Blouse, Dress, Dress Shirt & Sport Shirt Fabrics

ABSTRACT
This performance specification covers fabrics for woven blouses, dresses, dress shirts, and sport shirts. It is not however applicable to woven fabrics used for interlinings. These requirements apply to the length and width directions for those properties where fabric direction is pertinent. The fabrics shall meet the following performance requirements: breaking strength which shall be determined using a constant rate of extension tensile testing machine; resistance to yarn slippage; tearing strength; dimensional change during pressing and finishing, after laundering, or after dry cleaning; colorfastness to laundering and dry cleaning; shade change due to sodium hypochlorite bleaching or non-chlorine bleaching, burnt gas fumes, dry and wet crocking, perspiration, and xenon-arc light; fabric smoothness after pressing, laundering, and dry cleaning; and flammability.
SIGNIFICANCE AND USE
4.1 Fabrics intended for this end-use should meet all of the requirements listed in Table 1.  (A) There is more than one method that can be used to measure breaking strength, tearing strength and colorfastness. These methods cannot be used interchangeably since there may be no overall correlation between them (see Note 2 and Note 3).(B) See Note 5.  
4.2 It should be recognized that fabrics can be produced utilizing an almost infinite number of combinations of construction variables (e.g., type of fibers, percentage of fibers, yarn twist, yarn number, warp and pick count, chemical and mechanical finishes). Additionally, fashion or aesthetics dictate that the ultimate consumer may find acceptable articles made from fabrics that do not 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 this end-use.  
4.3 The uses and significance of particular properties and test methods are discussed in the appropriate sections of the specified test methods.
SCOPE
1.1 This performance specification covers fabrics for woven blouses, dresses, dress shirts, and sport shirts.  
1.2 This performance specification is not applicable to woven fabrics used for interlinings.  
1.3 These requirements apply to the length and width directions for those properties where fabric direction is pertinent.  
1.4 When a fabric requires special treatment, specific methods will be described as they are developed for that material, and such special tests will have precedence over these general requirements.  
1.5 The following precautionary caveat pertains only to the test methods described in this performance specification. This standard does not purport to address all of the safety concerns, if any, associated with its use. It is the responsibility of the user of this standard to establish appropriate safety, health, and environmental practices and determine the applicability of regulatory limitations prior to use.  
1.6 This international standard was developed in accordance with internationally recognized principles on standardization established in the Decision on Principles for the Development of International Standards, Guides and Recommendations issued by the World Trade Organization Technical Barriers to Trade (TBT) Committee.
