ABSTRACT:
To manufacture airbags comprising a contact fabric and/or a filter fabric it is proposed to use hollow fiber synthetic filament yarns having a hollow area fraction of 10-40%, based on the total cross-sectional area of the fiber. The closeness values are >72% for the contact fabric and 45-68% for the filter fabric. In addition to reducing the production costs, hollow fibers also make it possible to produce lighter fabrics. These have a beneficial effect on the working of an airbag.
