"polyamide filaments 56, fiber structure, airbag fabric, process for producing polyamide filaments 56 and polyamide resin 56". The present invention relates to polyamide filaments 56 capable of forming an airbag fabric more excellent for flexibility and impact-absorbing capacity than airbag fabric formed from conventional polyamide 66 filaments and also excellent for low permeability. air resistance, heat resistance and durability in good balance, a fiber structure containing said filaments and an airbag fabric. they can be obtained by polyamide filaments 56 having a relative sulfuric acid viscosity of 3 to 8, a mw / mn ratio of 1.5 to 3, a single fiber fineness of 0.1 to 7 dtex, a resistance 7 to 12 cn / dtex, a shrinkage rate of 5 to 20% after being treated with boiling water at 98 ° C for 30 minutes, a resistance of 5 to 11 cn / dtex after treatment with boiling water and a 10% elongation stress of 0.3 to 1.5 cn / dtex after treatment with boiling water. |
