Standard Performance Specification for Woven Blouse, Dress, Dress Shirt & Sport Shirt Fabrics
The following bibliographic material is provided to assist you with your purchasing decision:
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.
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 may involve hazardous materials, operations, and equipment. This standard does not purport to address all of the safety concerns, if any, associated with its use. It is the responsibility of user of this standard to establish appropriate safety and health practices, and determine the applicability of regulatory limitations prior to use.
Significance and Use
Fabrics intended for this end-use should meet all of the requirements listed in Table 1.
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.
Hence, no single performance specification can possibly apply to all the various fabrics that could be utilized for this end-use.
The uses and significance of particular properties and test methods are discussed in the appropriate sections of the specified test methods.
