Title:

POLYAMIDE FIBER AND AIRBAG FABRIC

Document Type and Number:

WIPO Patent Application WO/2013/084326

Kind Code:

A1

Abstract:

The purpose of the present invention is to provide a polyamide fiber from which a fabric appropriate for use in airbags is obtainable, and which exhibits weave-loosening prevention properties after weaving thereof, and excellent mechanical properties. This polyamide fiber is characterized by having: a total fiber density of 100-700 dtex; a tensile strength of 8.0-11.5 cN/dtex; a boiling-water shrinkage of 4.0-11.0%; a slack recovery rate (A) represented by formula (1) after a fixed-length heat treatment of 0-4.0%; and a tightening index (F) represented by formula (2) of 3.8 or higher. A = [(Ta-Tb)/Ta] × 100 (1) (In formula (1), Ta represents the amount of slack immediately after the heat treatment, and Tb represents the amount of slack at the time of stabilization after the heat treatment.) F = A + 0.35 × B (2) (In formula (2), A represents the slack recovery rate after the fixed-length heat treatment, and B represents the boiling-water shrinkage rate.)
