Coloration
In the case of transfer printing the colour/design is printed onto paper
and then subsequently transferred onto fabric. Special disperse dyes are
used which are able to sublime or vaporise directly from the solid form
and transfer onto suitable fabrics, i.e. fabrics constructed from hydrophobic
man-made fibres such as polyesters and polyamides/nylons.
It is possible to print colour onto fabric in the form of an insoluble,
inert pigment in a binder. The resulting print is baked and forms an image
of pigment in a clear polymer film. Washing off is not necessary, the
result is similar to a painted image rather than a dyed image. Flock may
be applied to a printed adhesive image to produce "flock prints". Special
printing materials are available which incorporate retro-reflective glass
beads in a binder, after baking the image has similar properties to retro-reflective,
high visibility garments.
