Abstract: Multi-filament polyamide yarns characterized by high tenacity and low shrinkage are disclosed. Such yarns or fabrics made therefrom can be used in industrial applications in which such a combination of properties is desirable. Such yarns are particularly useful in the manufacture of automobile airbag fabrics. Also disclosed is a process for making such yarns. The yarn manufacturing process involves spin-drawing molten nylon, relaxing and controlling the yarn tension, and then winding the yarn. Yarns made according to this process exhibit linear density in the range of 110-940 decitex, tenacity equal to or greater than 80 cN/tex, and shrinkage, measured at 177° C., of less than 5%.

Abstract translation: 公开了以高强度和低收缩为特征的多丝聚酰胺纱线。 由此制成的这种纱线或织物可用于需要这种性质组合的工业应用中。 这种纱线在汽车气囊织物的制造中特别有用。 还公开了制造这种纱线的方法。 纱线制造工艺涉及纺丝熔融尼龙，松弛和控制纱线张力，然后卷绕纱线。 根据该方法制造的纱线呈现在110-940分特，强度等于或大于80cN / tex的范围内的线密度，并且在177℃下测得的收缩率小于5％。
