It could be summarised, from results shown in Fig. 4,
that when a lower concentration of photoinitiator
(40 g kg1) was used (A group of samples), theUV-cured samples with 150 g kg1 of binder in printing
paste have the highest fabric stiffness. Expectations that
an increase of binder (200 g kg1) would give higher
stiffness values did not meet expectations. At higher
concentrations of photoinitiator (B and C group of
samples with 60 g kg1 and 80 g kg1) the trend is the
opposite. The fabric stiffness values were highest when
the lower amount of binder was used (100 g kg1), B1
and C1, respectively. UV-cured samples of the C1 group
are hard to the touch, independent of pigment
concentration, which could be attributed to higher rates
of photopolymerization and through-cure.
