2.3. Heat set and fixation
In order to fixation of the nylon nanofibers on the fabric surface,
the treated nylon samples were putted in an oven for 5 min at
80 8C.
2.4. Staining and irradiation
To determine color changes, the nylon fabric samples were
stained with a solution of Dark Green 6 (0.2 g/L). The fabric samples
were then exposed to UV lamp irradiation (Philips, HPA 400 s,
Belgium) for 6 h.
2.5. Durability to washing
Stability of the nanophotocatalysts is a particular requirement
for textiles because they are subject to frequent washing. The
coated nylon samples were washed under condition ofthe ISO 105-
CO2 Test Method condition to determine the photoactivity of
fabrics after 20 cycles laundering.
