My guess is, not well enough to bother with. I'm familiar with flame retardant cotton in another application: wildland firefighting clothing. It is used there because it is lightweight and breathable and generally the exposure to flames is low. Nomex is used for situations where the risk of exposure to flames is high, as in structural firefighting "turnouts". A chute protector pretty much has to withstand direct exposure to be of any value as a reusable item.

Hot black power particles are what destroy your parachutes. Any method that prevents these particles from impinging on you chute should work, provide the material doesn't burn.
I don't know about flame resistant cotton. If it doesn't burn when impacted with burning black powder particles it could work. Folks have suggested that you can go to a fabric store and purchase almuinized ironing board cover fabric and use it in small rockets as a chute protector.
The commercial parachute protectors are either kevlar or nomex. I'm not sure a pocket is large enough to provide protection,
You can also use a piston ejection scheme or a baffle system to protect the parachute from hot BP particles, but regular flameproof wadding, and cellulouse building insulation (not fiberglass!!!) work well and are easy to get.

I was trained a welder in the US Navy, and ran a welding and fabrication
business for 9 years.
To add to the above comments.
I know (and own) several of the jackets you are referring to. Cotton
naturally resists flames but will still burn, but also breathes and wick
sweat from the body. Cotton welding jackets are used to provide
some protection mostly from the UV radiation welders are expoded to
and allow some level of comfort versus wearing treated leather which
offer much better protection.
The cotton fabric is also treated with a fire resisitant chemical coating
which will wash and wear off over time.
To answer your question, yes it will protect the chute but it will have a
limited life time that I would expect to be significantly shorter than
Nomex and I would expect to be more expensive in the long run than
Nomex due to repeated replacements. Assuming you are purchasing
both.
When I was production welding in a week a cotton jacket would be
worn out and replaced. In 9 years the leather were only replace every
few years.
