Flock consists of synthetic fibers that look like tiny hairs. Flock print feels somewhat velvet and a bit elevated. The length of the fibers can vary in thickness which co-determines the appearance of the flocked product. Thin fibers produce a soft velvety surface, thicker fibers a more bristle-like surface. Flocking is defined as the application of fine particles to adhesive coated surfaces. Nowadays, this is usually done by the application of a high-voltage electric field. In a flocking machine the “flock” is given a negative charge whilst the substrate is earthed.
Flock material is applied vertically onto the substrate using glue. A number of different substrates can be flocked including; textiles, fabric, woven fabric, paper, PVC, sponge, toys and automotive plastic. The majority of flocking done worldwide uses finely cut natural or synthetic fibers finish imparts a decorative and/or functional characteristic to the surface. The variety of materials that are applied to numerous surfaces through different flocking methods create a wide range of end products. Koschaum flocks foams, foils and structural materials for automotive, industrial supplying, luxury packaging and cosmetics, and the flock can make a product waterproof, fire-resistant or extremely abrasion resistant. Koschaum also offers to provide a water repellent surface to prevent the absorption of moisture. Surfaces can also be provided with an antibacterial finish.
