The
high visibility garments are mainly used by the police forces, the road rescue
services, the fire brigades, the towns refuse collectors and many other workers
who want to draw attention to themselves as these materials are easily
recognisable. These garments must provide high visibility protection as
specified by EN 471:2003 standard,
they must be comfortable to wear and
stand up to daily use in hard working conditions. In this work, the colouristic and the fastness
properties of 100% PES fabrics dyed with two commercial fluorescent dyes were
investigated. Accordingly, 100% PES knitted fabric (rib, 265 g/m2)
was used for dyeing with fluorescent dyes, namely, C.I. Disperse Yellow 184/1
and C.I. Disperse Red 277. Each of these two dyes at various concentrations
(0.05% - 3% o.w.f.) and 1% o.w.f. dye mixtures were applied to the fabrics by
exhaustion method. In an additional study, 100% PES microfibre woven fabric
(118 g/m2) was also dyed with C.I. Disperse Yellow 184/1 and treated
with a water/soil repellent agent [Setapret FC (Setaş Kimya)] by a padding
application and fixation. The effect of the finishing chemical on the
colouristic properties of fluorescent dyed fabric was investigated.
The colour
measurements, repeatability of dyeings and the fastness (washing, staining, rubbing,
hot pressing and light fastness) tests were carried out and the colours were
evaluated in accordance with the chromaticity coordinates and the luminance
factors given in the EN 471:2003 standard.
