ABSTRACT:
Efficiency in the production of woven polypropylene fabrics is greatly improved through the use of an additive comprising fine silica particles. Addition of the abovesaid additive to the resin prior to extrusion of the ribbon yarns increases weaving efficiency, reduces burling time, decreases the frequency of weaving faults such as lost or broken picks, and permits the use of larger weft yarn packages.
