FAQ - Flock

Which kind of flock are available?

All textile fibres may be used as flock. However, most of the time polyamide, polyester, viscose and cotton are being used.

When is which kind of flock being used?

Generally, polyamide may be used in most cases. The other types of flock carry the following characteristics:
Polyester has more resistance to UV light as does polyamide and therefore carries advantages when used for outside purposes. However, the buckling stability is much lower.
Viscose is cheaper than polyamide but because of its lower buckling stability it is only used with soft substrates (textiles, soft foam).
Cotton is the most economic flock type, however, its general wear- and tear resistance is rather low. It is mainly used for the insides of rubber gloves (because of its water absorbing capability).

How are the typical flock dimensions selected?

A typical flock quality is:
Polyamide-cut flock 6.7dtex, 1.0mm.
The flock thickness is measured in ‘dtex’ and the length in mm. The length results in the density of the flock pile (i.e. the flock coat). The ratio thickness – length determines the touch of the flocked surface (the smaller the length - the softer), but it also determines the processibility of loose flock (the smaller it is – the more difficult it is to process).
The approx. limits are as follows:
Thickness : Length < 1 1 ... 5 5 ... 12 > 12

Processibility: not difficult good good
processible processible

Touch: --------- very soft normal prickly

Example: 6,7 :1 = 6,7 ~ 7 i.e. good processibility, see table

What does "dtex" means?

Dtex is a measurement for the thickness of textile fibres and means gram per 10.000 m of length.

Which colour may be chosen?

Basically, flock may be dyed with any colour shade which is possible for textile dyeing (flock fibres are textile fibres!).
One distinguishes between spin-nozzle dyed and batch dyed.
Special colour shades are also possible by mixing different colours (melange).
Individual colour shades are possible upon request.

How sturdy is flocking?

By an optimal co-ordination of substrate, adhesive, flock and the production process, very sturdy products may be achieved, such as for sports wear, upholstery fabrics, floor coverings, window guiding profiles, etc., which will function properly their entire production life.

Is flock combustible?

Polyamide flock will not combust at room temperatures. Only at more than 390° C (i.e. far above the melting temperature) polyamide might burn.
In the actual requirement a test for flame resistance is recommended.
