This is known behaviour of Nylons. They are all highly hygroscopic, so you have to keep it as dry as possible.
For storage, I put the spools in the plastic bags they came in, together with some extra desiccant bags and an indicator card. The cards have some spots that change color depending on humidity, I think, 10%, 30% and 50%. That helps me to know, if the spool is still dry enough.Then I put all that in an extra zipperbag.
For short prints (<2h) I don't care too much. For longer prints, I place the spoolholder and the spool into a bucket with cap and also put a bunch of desiccant bags into it.
For the dessicant bags, I found some, which change color when they are used up, so I know when to dry the dessicant in an oven or replace them.
What you say about the heated piece sounds interesting. I didn't have to dry the filament yet, but if I have to some time, I will take care of that
For the first part of the filament, which was heated by the nozzle: This should be only some centimeters right? Maybe just cut them off?
I'm excited because I've personally produced this showcase event, so if you are curious what else I'm up to nowadays, come check it out and say hi in the chat! It would mean a lot!

I knowed about the hygroscopic property of Nylon but I thought that would take many months, not few day^^
Yes you can cut some centimeters...
I bought some reusable desiccant bags, I look if it is reasonable to dry a moist filament with desiccant bags.
