Abstract
Abstract Combustible materials such as fiber is made flame retardant by treating the material with a methanol or water solution containing the newly discovered compound ammoniumtriborate (NH 4 .B 3 O 5 .3CH 3 --OH) or a methanolic solution of newly discovered methylborate ammonia adduct. These new flame retardants have the ability to penetrate the combustible material when applied as a solution and thereafter be converted in situ to ammoniumpentaborate to result in enhanced flame retardation over that achieved by merely the direct treatment with ammoniumpentaborate with other borate flame retardants.

Claims Analysis
Total Claims: 17
Claim 1
Independent Claim
47 words
A process for flame retarding natural and synthetic fibers which are subject only to dry laundering, which comprises applying ammoniumtriborate or a solution of ammoniumtriborate to natural fibers, synthetic fibers or mixtures thereof in sufficient quantity to provide a flame retarding amount of borates on said fibers.
Claim 2
Dependent Claim
47 words
A process for flame retarding natural and synthetic fibers which are subject only to dry laundering, which comprises applying ammoniumtriborate or a solution of ammoniumtriborate to natural fibers, synthetic fibers or mixtures thereof in sufficient quantity to provide a flame retarding amount of borates on said fibers.
Claim 3
Dependent Claim
20 words
The process of claim 1 wherein the fibers are in the form of cotton batting, furniture padding, upholstery or carpeting.
Claim 4
Dependent Claim
16 words
The process of claim 2 wherein the base materials are cellulosic, polyesters, polyurethanes, nylons or polyolefins.
Claim 5
Dependent Claim
21 words
The process of claim 2 wherein the said composition is applied by soaking-pressing or spraying followed by heat curing the fibers.
Claim 6
Dependent Claim
10 words
Flame retarded fibers prepared by the process of claim 1.
Claim 7
Dependent Claim
53 words
The process of claim 1 wherein a hot methanolic solution of ammoniumtriborate or a hot water solution of ammoniumtriborate is applied to the fiber by means of spraying and wherein methanol and ammonia is removed when a methanolic solution is used and water and ammonia is removed when a water solution is used.
Claim 8
Dependent Claim
50 words
A process for rendering flame resistant products manufactured from virgin, processed, reconstituted, or recycled organic materials or fibers, such as newsprints, wood chips, wood shavings, sawdust, wood panels, corn cobs, bagasse, peanut shells, and other dried plant matter which comprises applying to said materials or fibers a solution containing ammoniumtriborate.
Claim 9
Dependent Claim
50 words
A process for rendering flame resistant products manufactured from virgin, processed, reconstituted, or recycled organic materials or fibers, such as newsprints, wood chips, wood shavings, sawdust, wood panels, corn cobs, bagasse, peanut shells, and other dried plant matter which comprises applying to said materials or fibers a solution containing ammoniumtriborate.
Claim 10
Dependent Claim
12 words
The process of claim 7 wherein the solution is a methanolic solution.
Claim 11
Dependent Claim
21 words
The process of claim 7 wherein the solution comprises a water-methanol solution of ammoniumtriborate, ammoniumpentaborate and an inorganic or organic sulfite.
Claim 12
Dependent Claim
23 words
The process of claim 7 wherein the solution is a hot water solution which comprises ammoniumtriborate, ammoniumpentaborate and an inorganic or organic sulfite.
Claim 13
Dependent Claim
26 words
The process of claim 10 wherein the ammoniumtriborate-ammoniumpentaborate concentration is from 5 to 60% and the inorganic or organic sulfite concentration is from 1 to 5%.
Claim 14
Dependent Claim
60 words
A process for rendering flame resistant products manufactured from virgin, processed, reconstituted, or recycled organic materials or fibers, such as newsprints, wood chips, wood shavings, saw dust, wood panels, corn cobs, bagasse, peanut shells, and other dried plant matter which comprises applying to said materials or fibers an anhydrous methanolic solution containing a flame retardant effective amount of methylborateammonia adduct.
Claim 15
Dependent Claim
60 words
A process for rendering flame resistant products manufactured from virgin, processed, reconstituted, or recycled organic materials or fibers, such as newsprints, wood chips, wood shavings, saw dust, wood panels, corn cobs, bagasse, peanut shells, and other dried plant matter which comprises applying to said materials or fibers an anhydrous methanolic solution containing a flame retardant effective amount of methylborateammonia adduct.
Claim 16
Dependent Claim
27 words
Flame retardant fibers which are subject only to dry laundering and which contain ammoniumtriborate wherein said fibers are made by incorporating ammoniumtriborate in situ to produce ammoniumpentaborate.
Claim 17
Dependent Claim
27 words
Flame retardant fibers which are subject only to dry laundering and which contain ammoniumtriborate wherein said fibers are made by incorporating ammoniumtriborate in situ to produce ammoniumpentaborate.
