The effect of hydrophobization of PA6 nanofiber layers with fluorocarbon and hydrocarbon finishes on physiological comfort properties

Roman Knizek, Daniela Lubasova, Vladimir Bajzik

Abstract

This study investigates the impact of two hydrophobic finishing agents—fluorocarbon-based Nuva FDS and fluorine-free Ruco-Dry ECO Plus—on the performance of polyamide 6 (PA6) nanofibrous layers fabricated via needle-less electrospinning (Nanospider™) and finished using a foulard process. Both finishes significantly enhanced water repellency, with Ruco-Dry ECO Plus achieving a maximum hydrostatic pressure resistance of 7360 ± 470 mm H 2 O. Contact angle measurements averaged ∼130° across all treated samples, indicating consistent hydrophobic surface modification. Water vapor resistance (Ret) ranged from 0.81 to 1.08 Pa·m 2 /W, and air permeability values remained relatively stable between 2.98 and 2.62 L/m 2 /s. These results confirm that both agents effectively balance water resistance and breathability. Moreover, the fluorine-free Ruco-Dry ECO Plus offers a sustainable alternative without compromising functional performance. This scalable finishing approach supports the development of environmentally responsible, waterproof-breathable textiles. Future research will focus on wash durability and long-term performance under real-world conditions.
