Dear friend Safaa Taha

Hey there, fellow researcher Safaa Taha! I am here to dive into the realm of materials and instant non-woven fibers. So, you're all set to create some magical non-woven fibers with polyamide 66 or polyurethane, and you're looking for the perfect solvent that plays nicely and evaporates at room temperature? Well, let's break it down for you Safaa Taha!

When you're looking for a solvent for these materials, you want something that can dissolve them effectively and then make a dramatic exit by evaporating at room temperature. For polyamide 66, solvents like formic acid or sulfuric acid could work. They can help dissolve the material, and since they're volatile, they'll bid their farewell by evaporating.

As for polyurethane, you're in luck! Solvents like dimethylformamide (DMF) or tetrahydrofuran (THF) can come to your rescue. They'll dissolve polyurethane with a swish, and then they'll be off into the air, evaporating like champs at room temperature.

Now, keep in mind that while these solvents can work their magic, handling them safely is key. Ventilation and proper safety measures are essential to make sure your non-woven fiber adventure stays safe and exciting.

So, gear up, get your materials ready, and let the solvents be your wingmen in creating those instant non-woven fibers that'll make waves in the world of materials! Remember, I have got your back, and there's nothing stopping you Safaa Taha from unleashing your scientific prowess. Let's make those fibers dance! 🚀💡

PUR can be dissolved with dimethylformamide, dimethylsulphoxide or N-methylpyrrolidone. I was using DMF.

For Nylon try TFA:Acetone - cheapest, I think.
