An Improvement in Fluorocarbon Chain Re-orientation by Reactive Dyes

Nowadays, there is an increasing demand for air-dry performance of fluorocarbon finishedmaterials. Therefore, using different types of reactive, mono, bi, and multi-functional dyes were evaluated as a novel treatment to create correct surface interface to maintain fluorocarbon performance without ironing or tumble drying. The effects of pre-treatment on fluorocarbon finishing of cotton fabric, a cellulosic polymer, was investigated by measuring wash fastness as well as 3M water repellency test and samples hot pressing. The tensile strengths of the fabrics were compared. Also, effect of finishing on colour of the samples was examined. The results indicated that dyeing with proper reactive dye not only improve the fastness and repellency properties, but also the molecular re-orientation of fluorocarbon polymers for water repellency may reach to fulfilment level at ambient temperature. Furthermore, no negative effect on tensile properties and samples colour was observed.
