Foil kite drying, cracked it.

Postby Foil » Thu Jul 25, 2019 9:15 am

Colin's drive in kite wash and dry service,
It takes an hour to dry the internals after an Ooooops moment at sea,
I did notice that if I left a damp kite in the car then the sea water left a slightly tacky feel to the cloth, and the tiny condensation droplets stayed inside "forever" :o

The hairdryer is mine, not Paulines! Bought especially for the foil kites, the diffuser on the end stays in place trapped inside the zip opening, set on low but super fast fan inflates the kite quickly with great airflow to dry out the damp, eventually🤗

I use to do this with my speed1 13metre , if i'd had a rain moment at the beach or the beach was exsessively wet at home in the diner kitchen , put a hair dryer up each end obviously on cold , it is the quickest way to dry out a closed foil , i don't have a very big gardenor a lawn so i have to improvise -this last week i did the mixer on a pulse2 6metre, on a psyhco4 8metre , and yesterday i did it on my spd2 10 metre delux, all by laying part of the kite on a dog blacket on the bed and putting a small snap shackle on the wardrobe ring handle and connected the lines on that ,layed weight on the doors,so they couldn't open and layed the lines out one half at a time it worked quite well

Agreed, we all need to dry out our drowned/rained on foil kites but, just remember foil kites are designed for very low internal pressures, and leaving it in the sun introduces uv breakdown…

Using a low enough pressure to barely in inflate the kite in a sheltered area for a short time should be fine.

Using enough pressure to semi firmly inflate the kite is like adding flying time with regards to porosity increasing.

Inflating firm is beyond the intended design and will make the kite fabric permanently more porous.

Used paragliders are tested and deemed unsafe/non-airworthy/worthless when they become too porous. I have not seen foil kite porosity standards published.

After you land your kite and see how it seems to deflate quicker than it used to, you’ll know your kite is not new and may not perform like new any longer…

yes I agree ,
the leaving it in the garden on the clothes drying line was a worry in the sun, foil kites seem to attract the need for lots of care in the washing and drying department, luckily my car port is fitted with solar screen panels to filter out the harmful rays, that was to protect the paintwork on my car, but now i am glad they are fitted.
as for the air tightness issue on older kites, my foiling buddy had exactly that problem on his old chrono foils, 1 and 2 series, signs were absorbing water too quickly when dropped into the sea, he cured this problem by hanging the kite up outside on a calm warm day and spraying the whole kite with the waterproofing spray you can find in big outdoor stores, he was very happy with the results as it did work well, the only problem was it it only lasted a year and needed redoing,
has anyone else done this? if so which brands work and which are best given a miss,
all mine are new so don't need to worry about it yet, but its stuff that's good to know.

another foiling buddy has a much older kite that soaks up the sea far too easily, or are the older kites more prone to this as they use less well developed materials that are now available.

and are the new ultra light materials we now see more resistant to this than the standard "softer"more durable cloth.or is it just lighter and just as durable?

We live in a house with a tall attic that heats up into the high 90s F daily. I strung a clothesline and hung my Soul for 2 days. Crispy dry.

Agreed, waterproofing can be helpful. The coating inside my chrono1 also separated from the fabric on the inside wingtips. viewtopic.php?p=1055325#p1055325

Porosity increases as particle density decreases, https://www.wikihow.com/Calculate-Porosity and at sea level, air is 784 times less dense than water and dirt is about 2.5 times the density of water. https://www.theweatherprediction.com/habyhints/216/

Waterproofing fabric is common, and keeping it breathable is usually a good thing for most fabrics so they let water vapor out. Most “fabric sealing” products help waterproofing, but not so common is the need to seal it from airflow. I did some previous experimenting to try a seal a very porous kite: viewtopic.php?p=964584#p964584

Hopefully you won’t need to do anything like a styrene butadiene rubber coating to the newer type fabrics used on your kite.

I was wondering if inflation with the hair dryer to higher pressure than self inflation was harmful...
My wife is peaceful person. She'll just give passive aggressive treatment.

I am not worried about the hair dryer being on full speed as the kite is still soft feeling and the air is rushing out of the two open drain holes at the tips, if anything the ends feel softer than when grabbing hold for an assisted landing, I worry more about when rolling/folding the kite up and when I get to the last 8 or 10 cells the trapped air can really feel quite tight and the temptation is to push hard to squeeze it out, best not to i think, as that feels so wrong, but not as bad as the tricks i have seen others use like falling full body weight over the last part of the kite to force the kite flat, Yikes! that looks bad for the material :nono:
gently gently for me :heartface:
