hi i'm fiona bell
and let's talk self-destaining textiles
traditionally stains are unintentional
and unwanted
resulting in a strong desire to reduce
the stain
dyes are intentional and wanted having a
rich history
in textile design so
what if we can destain textiles
in this work we see stains as a mark we
can interactively destain
to create aesthetic patterns rather than
seeing stains
as something negative we thus introduce
self-destaining textiles which are
interactive textiles
that degrade organic stains using light
our self-destaining textile works by
applying a photocatalytic coating
to the surface of the textile that when
exposed to light
degrades stains we use a colorometer
instrument to measure color intensity
and we calculate this stain degradation
based on those measurements
we call these self-destaining textiles
because all of the components for stain
degradation are embedded within the
textile itself
creating a self-destaining textile takes
five
steps coating staining
led integration programming the textile
and light exposure we start by coating
cotton
with silver doped titanium dioxide
nanoparticles
which degrade stains when exposed to
light
we first explored three methods of
coating the cotton with nanoparticles
painting spraying
and immersing painting yielded the best
results
over spraying and immersing we then
coated a double woven
cotton textile with pockets designed to
hold leds
after the coating cured we stained our
textile
with coffee a common unintentional stain
we then embedded programmable leds
by placing them inside the textiles
pockets
to make this decision we explored three
possible embedding options
the led on top of the textile the led
within a cut
hole and the led underneath the textile
our measurements indicated that
embedding the led
underneath the textile provided the best
light intensity 4d staining
we then wired the leds to an arduino
board
and programmed them to show our
destaining design
as you can see we experimented with a
cross
and a square led pattern
lastly we triggered our self-destaining
textile by exposing it to light
the intensity of the light and exposure
duration
played key roles in self-destaining with
the color of the stain degrading more
over time
and faster at higher light intensities
after 24 hours of led exposure our
self-destaining textile
degraded our desired pattern
we further explored passive interactions
and controlled interactions that the
user can have
with the self-destaining textiles
for passive interactions we used
laser-cut stencils to create a set of
photograms
that reveal patterns through passive sun
exposure
over 24 hours in this perspective
we use the stained textile as our empty
canvas
light as our paint and stencils
as our paint brushes we also
create a hair tie that self-destains
when passively exposed to sunlight
revealing
patterns unique to the user's
experiences
movements and environments allowing them
to encode the memory of a special day
into a tangible object for
controlled interactions we experimented
with embedding leds into a woven swatch
we also created a station where we can
place the self-destaining textile
on top of a programmed led matrix
we use this station to pattern a phone
case to obtain
a new design the user can simply restain
reprogram and re-expose the textile
in conclusion we developed
self-destaining textiles
that interactively degrade stains to
create aesthetic
patterns thank you all for listening i
want to
give a huge shout out to all my
co-authors and i am now
happy to take questions
