Non-inflammable was a big deal because previous hair clips were made of celluloid - which was VERY flammable !

(The  flammable and inflammable mean exactly the same thing: easily set on fire and capable of burning quickly. 
Of the two terms, the older word for something capable of burning is inflammable, but early in the 20th century the word flammable was coined as a  for inflammable. 
So non-inflammable means NOT easily set on fire !)
