20020150758, Oct 17, 2002

Filed:

Apr 15, 2002

Appl. No.:

10/122839

Inventors:

Juan Prieto - Hallandale FL, US

International Classification:

D02G003/00

US Classification:

428/375000, 428/393000

Abstract:

The present invention is a fire resistant cellulose insulation material made from agricultural byproduct containing cellulose fiber, comprising: cellulose fibers that have been bathed in an effective amount of a first aqueous solution of chemicals suitable for separating and partially dissolving said cellulose fibers, followed by an effective amount of a second aqueous solution of chemicals suitable to neutralize said first aqueous solution, and a fire retardant chemical produced from the neutralization of said first aqueous solution by said second aqueous solution, said fire retardant chemical precipitated on said cellulose fibers. A method for making same is also disclosed and claimed.

Abstract:

An apparatus for production of fire-resistant cellulose material from agricultural byproducts containing cellulose fiber, comprising a first bath for washing said agricultural byproduct cellulose fiber material, a second bath for receiving and mixing said washed agricultural byproduct cellulose fiber material with an effective amount of an aqueous solution suitable for separating said cellulose fibers, conveyer means disposed between said first bath and said second bath for receiving said separated cellulose fibers and moving washed said cellulose fibers to said second bath, and a third bath for receiving and mixing said mixture of separated cellulose fibers produced in said second bath with an effective amount of an aqueous solution suitable for neutralizing said mixture and for producing a fire retardant chemical precipitated on the surface of said cellulose fibers, and conveyer means disposed between said second bath and said third bath for receiving said separated cellulose fibers and moving said separated cellulose fibers to said third bath.
