Standard Performance Specification for Bathrobe, Dressing Gown, Negligee, Nightgown, and Pajama Fabrics
The following bibliographic material is provided to assist you with your purchasing decision:
This performance specification covers fabrics used in bathrobes, dressing gowns, negligee, nightgown, and pajamas. The breaking strength, tearing strength, yarn distortion, yarn slippage resistance, bursting strength, bleaching, burnt gas fumes, crocking, perspiration, light, fabric appearance, and flammability shall be tested to meet the requirements prescribed.
Scope
1.1 This performance specification covers fabrics used in bathrobes, dressing gowns, negligee, nightgown, and pajamas.
1.2 These requirements apply to the length and width directions for those properties where each fabric direction is pertinent.
1.3 The following safety hazards 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 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 fabric can be produced utilizing an almost infinite number of combination 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.

A There is more than one method that can be used to measure breaking strength, tearing strength, bursting strength, and lightfastness. These methods cannot be used interchangeably since there may be no overall correlation between them (see Note 2, Note 3, Note 4, and Note 5).
