Abstract

For producing woven fabrics for air bags and other industrial applications, an intermingled unsized synthetic filament yarn is used with a yarn titer of 100-1000 dtex. The individual filaments of the yarn have a titer not exceeding 5 dtex. The yarn exhibits a mean opening length of 2-10 cm, the coefficient K1 for the stability of the intermingling points of the yarn exceeds 0.6, and the coefficient K2 for the stability of the intermingling points of the yarn exceeds 0.3. This yarn can be used to manufacture industrial woven fabrics with the required properties, in particular woven fabrics for air bags, in a cost-effective manner.
