vochtafvoerend

Vocht afvoerend describes the property of a material to transport moisture away from a source, typically from the skin or interior to the outside. In Dutch usage, vochtafvoerende materials are those that move moisture through a fabric or barrier, enabling it to evaporate at the outer surface. This involves mechanisms such as capillary action, hydrophilic transport within pores, and diffusion of water vapor.

In textiles, vochtafvoerende fabrics wick moisture from the body to the outer surface where it can evaporate. This helps keep the wearer dry and comfortable during activities. The effect depends on fabric structure, fiber chemistry, and finishing treatments that promote moisture movement. Vochtafvoerend clothing is common in sportswear, underwear, and outdoor apparel, often marketed as “wicking” or moisture-management fabrics.

In building and construction, vochtafvoerend or breathable materials allow water vapor to escape from interior spaces while limiting the ingress of liquid water. Such materials support condensation control and mold prevention, contributing to indoor air quality and durability of structures. They are used in membranes, underlays, and some cladding systems, forming part of broader moisture-management strategies.

Factors influencing performance include ambient humidity, temperature, air movement, and the moisture load. Proper design and use are essential, as excessive moisture transport can cause discomfort or, in buildings, condensation if ventilation is insufficient. Cleaning and wear can also affect wicking and breathability.
