ABSTRACT:
The present inventon relates to methods for rendering materials inflammable, and in particular, to methods for preparing fireproof feathers.
According to the present invention, a process for preparing fireproof feathers comprising steps of: (a) suspending a predetermined amount of feathrs in water to make a suspension of the feathers; (b) adjusting the pH of the suspension to lie within the range of pH 2-4 with acid to make a acidic suspension; (c) adding tetrabromophthalate derivative which is emulsified in water in advance and a water soluble compound to the acidic suspension, where the water soluble compound is preferably selected from the group including zirconium fluoride and titanium fluoride, and more preferably from the group including potassium zirconium fluoride and the hydro-acid of titanium fluoride; (d) resuspending and wahsing the feathers in water; and (e) drying the thus processed feathers.
In this way, fireproof feathers can be prepared easily and efficiently without adversely affecting the softness or other properties of the feathers.
