“…The absence of such a finish, in the case of PA/PES material, although it had the highest linear density of weft and warp, but also the lowest thickness ( Table 2 ), contributed to a significant decrease in water repellency after the first wash ( Figure 5 ). These observations are consistent with the findings of Schellenberger et al [ 10 ], Chowdhury et al [ 18 ], and Davies [ 19 ], who showed that hydrophobic finishes devoid of fluorocarbon compounds have lower efficiency and durability, compared to fluorocarbon finishes.…”

“…Alternative compounds are increasingly being used to impart hydrophobic properties to materials, including short-chain SFPs or non-fluorinated finishes (PFC-free finishes), which include paraffins, silicones, dendrimer chemicals, and nanoparticles [ 14 , 15 , 16 , 17 ]. However, as was shown by the results of Schellenberger et al [ 10 ], Chowdhury et al [ 18 ], and Davies [ 19 ], hydrophobic finishes devoid of fluorocarbon compounds have mostly lower durability, compared to fluorocarbon finishes. The study conducted by W.L.…”

The aim of the research was to evaluate the changes in the surface properties of five functional clothing materials with water-repellent finishes (including PFC-free finish) after 1, 5, and 10 washes with three detergents. A new approach to the interpretation of the water-repellent properties of textile materials is presented, based on two techniques, i.e., the spray test method and contact angle measurements. The results showed that washing materials with hydrophobic finishes can cause significant changes in their properties, which are mainly dependent on the composition and structure of the material, as well as the type of hydrophobic finish. The PFC-free finish is the least resistant to washing. For all materials with PFC finishes, the water repellency depends on the fluorine content on the surface and fabric topography. It was also found that increasing washing frequency resulted in a gradual decrease in water repellency. The loss of water repellency below an acceptable level (Grade 3) occurred after the fifth washing for all materials. Significant differences in the interpretation of the results of the spray test and contact angle measurements were observed. Using these methods separately provides information on the changes in the surface properties of the tested materials; however, their parallel application allows for obtaining complementary data, which is important for the proper interpretation of results.
