Anyone else ever burnt a hole in their kecks, from a drop of superglue
dripping on them ? Heat build up from fineness of threads or chemical
make-up of the cloth?




When I've spilled a drop of superglue on my pants,it just leaves a dark
spot that is hard and inflexible,and that doesn't wash out.

HTP can burst into flames when spilled on dirty fabrics.

Once when repairing the PCB runners on an ABS monitor case, that a
previous
repairer had mucked up with solvent glue, I'd superglued most of the
shattered fragments of ABS back in - but a lot was just crumbs.

What I used to fill the gaps, was cigarette ash and superglue, a plug of
ash
soaked in superglue is like granite - I noticed that the effect of ash on
superglue was that it set hard instantly, and produced a lot of heat in
doing so!



If the cloth had been touching skin I would have got a burn. Don;t know
what
temp it got to or whether it was smoke or steam rising from the patch. It
turned into a burnt hole with a surround of metal-hard ex-fabric around.
Probably a volume to surface area effect. Cigarette papers are paassed
through a multi EHT discharge process to create millions? of micro pores
in
the paper to assist "draw".
Don't know what my kecks were made from, as label is washed out , but
presumably polyster and cotton fibres.

Once upon a time I watched an engineer spill a large pot of superglue on his
bench
he tried to wipe it up with an old cotton cloth only to find it on fire and
stuck to his hands.
Being helpful I went over and put out the flames and the smouldering cloth
only to find
my feet stuck to the floor!
You would have thought that I would have learnt from this but 10 years later
when someone annoyed me I superglue his shoe laces together, cotton again
and very worrying when your shoes are smouldering and you can't get them off
cause some idiot has glued them.
