Wool felt or synthetic?

Hi,

I am looking for a supplier of felt to cut on my machine. Melange colours that are quite thick (3mm thick minimum). Any ideas of where to find it and should I be looking at 100% wool or synthetic fibres?
Thanks

I don't know of a supplier but wool felt stinks and stays smelly after cutting!

Recycled synthetic felt cuts well.

also, I'm pretty sure , somewhere in my memory banks, I've read that burning wool gives off cyanide gas .
So worth checking and making sure you're extraction and ventilation is all spot on :-)

very quick google confirms, you should be careful ;)

"HCN is extremely toxic and seriously affects the body. Following are some facts about hydrogen cyanide3:
HCN is 35 times more toxic than CO.
HCN is produced when products such as wool, silk, cotton, nylon, plastic, and polymers, foam, melamine, polyacrylonitriles, and synthetic rubber burn.
HCN can enter the body by absorption, inhalation, or ingestion and targets the heart and brain.
HCN can incapacitate a victim within a short time.
HCN has a half-life of one hour in the blood.
HCN is highly flammable, and most of it will burn away during combustion.

I think you need to put it into context, we're not talking about any discernable levels of HCN being produced laser cutting and engraving sheeps wool felt. Maybe a warehouse or factory full of the stuff going up would pose a significant risk, which is more relevant to the link posted.

As for the smell and charing I believe there are ways to get rid of it, though best to vent to atmosphere I guess as even a filter unit won't take away the funky aromatics

Believe me the smell of a small bit of 100% sheep wool felt being cut (even in a well ventilated room) and the lingering memory is not something I will forget in a long time!! :lol:

Cutting acrylic and wood should be fine but common sense should prevail - any other material should be checked, if in doubt leave it out :)

Thanks for all the advice. I've gone with polyester felt in the end, it's 3mm thick but having to inmport from holland. Though price is good and the quality it great as long as you order 10m ++
Cutting at so 2O power 22
