Assessment of physical properties of fibres from thermoplastic polymers by means of tensiometric tests

Evaluation of the possibility of using surface free energy study to design protective fabrics

“…Therefore, studies have been carried out to work out the method for measuring the contact angle, appropriate for textile materials and based on both the modification of the goniometric technique itself, involving mathematical simulations 14,15 and the application of other methods of contact angle measurements. [15][16][17][18][19][20] Until now, the results of the studies on textile materials with the use of the Washburn (W) method have mostly been reported. 19,20,[22][23][24] The aim of this study was to analyze the differences in the contact angle values, measured with the use of two methods: the dynamic contact angle (DCA) method, [16][17][18] and the Washburn method, [19][20][21] as well as the differences in the values of SFE calculated with the use of three mathematical models (Owens-Wendt, Wu and van Oss-Chaudhury-Good).…”
