Abstract
The effects of fluorocarbon finishing of hollow and solid polyester/wool have been studied in order to establish the processing behaviour and performance characteristics of the treated fabrics. Polyester/wool blended fabrics before and after dyeing were treated with different fluorochemicals; their liquid repellency after washing and dry cleaning were evaluated. Fabric tensile properties and fabric hand were studied. The results indicate that finishing agent formulation has a great effect on the fabrics repellent properties. Studying the fluorocarbon chain re-orientation during laundering and dry cleaning revealed that each fluorocarbon has different ability to retrieve its original configuration via air drying with the necessity of subsequent hot pressing to reach acceptable repellency. Also, while the effect of hollow fibres on fabric mechanical properties is practically insignificant, the performance of solid fibre based fabric is superior. Evaluation of the low stress mechanical properties indicates that there are relatively small differences among the samples. However, finishing with all chemicals and different methods resulted in higher friction between the fibres and yarns with increased bending and shear rigidity, and shear hysteresis.
