Effects of microwave treatment on fluorcarbon finishing

A new device for microwave (MW) planar treatment of textile materials has been constructed. This laboratory device effectively simulates industrial one, which is not in the usage yet. Results of water- and oil-repellency obtained on planar MW apparatus have been compared with the ones obtained using conventional curing treatment. Simultaneous drying and curing processes have been conducted with MW at planar microwave device for the first time. Microwave technology in textile finishing offers better effects than conventional curing at tenter frame. Only in the case of durability to washing, cotton material treated with microwaves has shown a decrease. Lower effects, primarily caused by deorientation of fluorocarbon (FC) chains, have been improved with thermal re-activation performed after washing and dry cleaning. Greatest advantages of the microwave device constructed are lower production costs and the elimination of separate drying procedure. In this way, conventional treatment, which might cause uneven effects, is eliminated.
