- Abstract
The research project "ProSize" investigates the effects of hybrid yarn properties on processability in the fiber spraying process. Simultaneously spun glass fiber / polyamide-6.6 (GF / PA 6.6) hybrid yarns with adapted sizing formulations are being developed. The use of commercially available hybrid yarns leads to quality variations, therefore process-adapted sizings have been developed. The investigations focused on the cutting ability and electrostatic charging of the hybrid yarns. It was found that there is no significant correlation between electrostatic charging and the processability of the yarns. The use of antistatic agents had only a minor influence on the behavior of the yarns. By using process-optimized hybrid yarns, the bending strength could be increased and the fiber orientation improved. The project was funded by the Federal Ministry for Economic Affairs and Climate Protection.
