【摘要】: A measurement of a fabric''s edgecomb resistance indicates the relative tendency of a fabric to pull apart under seam stress or similar action. The related concepts of yarn slippage and seam slippage are limited to sewn seams, whereas the measurement of edgecomb resistance is made at the edge of a cut part in the absence of a sewn seam. The absence of a sewn seam in this test method eliminates the effect that a particular stitch might have on the tendency of a yarn to slip near an edge of a cut part This test method is useful for material design evaluations in such applications as airbags in which seam stress is a major concern. This method may be used as a complement to Test Method D 5822.1.1 This test method covers the procedures for determining the resistance to edgecombing of a woven fabric used in inflatable restraints. 1.2 Procedures and apparatus other than those stated in this standard may be used by agreement of purchaser and supplier with the specific deviations from the standard practice acknowledged in the report. 1.3 The values stated in either SI units or inch-pound units are to be regarded separately as standard. The values stated in each system are not exact equivalents; therefore, each system must be used independent of the other. 1.4 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.
