Flock technology

The 3D structure between two textile surfaces can be produced with the flock technology. In this technology, short cut fibres (flock fibres) are electrostatically charged and applied on adhesive coated substrate using an electric field. The flock technology is over 100 years old and is used in various technical, medical and textile sectors. The so-called filter-flock method is a process to improve the characteristics of spacer fabrics. The ribs made with flock, also known as rib-flock , allow for a greater conduction of excess heat and body moisture from the body due to their channel-shaped structure (cf. Section 14.3 Krel et ah, 2005 Machova et ah, 2006).

Intensification of aggregate transport to the surface of rising bubbles is currently of great practical interest since the development of flotation technology of small particles involves flocculation (Babenkov 1977, Veister Mints 1980, Dobias, 1993) and the transport of flocks is more efficient.
