Definitions
- This invention relates to compositions suitable for producing a weather-resistant flameproof finish upon readily combustible fibrous material, such as paper, wood, leather and textiles of ani mal or vegetable origin. This invention further relates to novel, weather-resistant and flameproof fibrous materials produced by the use of said compositions.
- a flanieproof fibrous material is defined as one which, if tested in a draft-free room by putting in contact with an initiating flame, will not continue to flame of its own accord for more than 5 seconds after removal of said initiating flame, and will not sustain combustion by afterglow beyond the charred area upon removal of said initiating flame.
- Flameproof fibrous materials of the above qualities in gen 'al are not novel. It is old to coat pap-er and t "'iles with heavy metal oxides such as oxides of tin, lead, antimony, arsenic, bismuth, titanium and the like, and to decrease their combustibility thereby. It is also old to impregnate, coat, saturate, or otherwise surface-treat textile fabrics with heavy metal oxides and water-insoluble, chlorine-containing organic compounds having fire and waterproofing qualities. The latter are generally applied from an organic solvent, which sometimes also acts as a vehicle for the metallic oxide.
- a further object of this invention is to produce flameproof fibrous material, for instance cellulosic textile material, which shall not develop appreciable tendering in outdoor use.
- a further object of this invention is to provide coating compositions for achieving the purpose composition of the above nature which is stable against separation of ingredients, and may be handled in commerce and stored for considerable periods for ultimate use by a consumer.
- the aforegoing objects are achieved by incorporating into the flameproofing coating composition, in addition to the metallic oxide and chlorinated organic compounds aforenoted, an anti-tendering agent which is the water-soluble reaction product of formaldehyde upon a mixture of a watersoluble alkaline-amine-proteinate and a reagent of the group which form water-soluble intermediate resins with formaldehyde, such as urea, adipamide, melamine and phenol.
- an anti-tendering agent which is the water-soluble reaction product of formaldehyde upon a mixture of a watersoluble alkaline-amine-proteinate and a reagent of the group which form water-soluble intermediate resins with formaldehyde, such as urea, adipamide, melamine and phenol.
- a still further object is to provide a mixture of an alkaline-amine proteinate and urea aerarea or its equivalent (phenol, melamine, etc.) as the protein-resin reaction product" or proteinresin composition, although it will be clear from the above discussion that the mass is an aqueous suspension containing water-soluble constituents and does not actually become converted into a water-insoluble resin until applied to the fiber and heated to 100 C. or over.
- the protein material entering into the composition of the aforegoing protein-resin reaction products may be of either animal or vegetable origin; for example, casein, glue, soyabean protein or zein. All of these are characterized by the common property that they will react with ammonia, quaternary ammonium bases, 01 aliphatic amines, especially polyalkylol amines, to produce compounds soluble in water. I shall refer hereinafter to such compounds as solubilized proteins or as aikaline-amine-proteinates.”
- the other component may be the reaction product of formaldehyde and an amide such as urea or adipamide, formaldehyde and an amine such as melamine, or formaldehyde and phenol.
- the flameproofing-property of the treated material generally increases with the chlorine content of the treating agent, although intermediate percentages of chlorine, say 40 to 65%, are preferred in most cases.
- the metal compound may be antimony trioxide, tetraoxide or pentoxide, tin oxides, bismuth oxides, arsenic oxides or any water-insoluble compound of these metals which will yield the oxide when heated, for instance the respective sulfides or the metals themselves.
- the usual method 7 of application is to disperse the metal oxide in an organic solvent solution of the chlorine-containing compound and apply the mixture in one operation.
- Such a material corresponds to a solvent-carried paint.
- the anti-tendering agent of this invention in other words, the aforesaid protein-resin reaction product, may be employed to produce aqueous suspensions of the aforegoing mixed flameproofing agents, wherein it acts both a a dispersing agent and as a protective bufier against the development of excessive concentrations of hydrogen chloride.
- the proteinresin buffering agent of this invention and the chlorinated organic fiameprooflng agent above discussed may be applied to the fabric separately, from separate organic solutions or aqueous suspensions.
- the protective agent of this .invention acts also as a dispersing agent, and as a binding agent for the other ingredients.
- additional, extraneous dispersing agents and binding agents may be added if desired.
- fungicides may be added in the form of insoluble pigments or in the form of compounds soluble in the chlorinated organic agent; again, if desired, they may be added as a separate dispersion. Waterproofing materials may be similarly added when desired.
- any of the customary special agents may be added to the coating composition to achieve special effects such as mildew resistance, rot-resistance, plasticity, coloring, etc.
- auxiliary or special agents are: Salicylanilide (mildew resistance); zinc-dimethyl-dithiocarbamate (mildew and rot-resistance); inorganic coloring pigments such as lead chromate, iron oxides, chrome oxides, and organic pigments such as vat dyes, azo dyes and phthalocyanines; organic colors which are soluble in the chlorinated compound; parafiin wax (waterproofing); and plasticizers such as tricresyl phosphate and the butyl phthalates. Additional buffering agents, for instance water-insoluble calcium or magnesium carbonates may also be added.
- the amount of protein-resin reaction product used is usually determined by the amount of dispersing agent needed and the flexibility of the applied film desired.
- the four fundamental ingredients of the present fiameprooflng compositions may be varied in amount as follows:
- Per cent Protein-resin composition 5 to Metal compound 5 to 40 Chlorine-containing organic compound 10 to 40
- Water 5 to 40 They may be applied to the fibrous material in concentrated form (up to 80% solids), or they may be diluted with water.
- the method of application may be dipping, brushing, spraying, or other means of coating or impregnating.
- the application to textile fabrics is generally carried out by immersion, squeezing and drying at elevated temperatures.
- the composition does not need to penetrate deeply to be effective. Good penetration of the interstices of materials such as cotton cloth is desirable when colored compositions are applied. Sufficient penetration is usually obtained when the material i absorbent such as bleached cotton while unbleached cotton is usually resistant to wetting by water and resists penetration.
- Alcohols are the preferred wetting assistants, since they do not interfere with the effect of waterproofing agents where such are required.
- Ethyl alcohol is soluble in water while hexyl alcohol may be dispersed in the composition'or added as a separate dispersion.
- the drying step in the? application of these products may be carried out at ordinary temperatures or at temperatures up to 300? F. 'or higher.
- the higher temperatures are preferred when fastness to water is required.
- considerable fastness to water may be obtained by drying at room temperature.
- compositions of this invention may be applied to any readily inflammable fibrous material such as wool, silk, cellulosic fabrics, ropes, sheets or articles of wood or paper to render them resistant to burning.
- Treated materials such as cotton fabrics, paper, rope and wood require varying amounts of added finish to obtain a flameproofing eflect.
- Heavy weight fabrics can be proofed with less added finish per unit weight than light-weight fabric since the finish does not completely penetrate, and approximately the same amount is required for the same surface area.

- the antimony sulfide was dispersed in the protein-resin agent and 10 parts of the water by high-speed agitation, followed by the chlorinated paraflin wax and the remaining water. A stable black dispersion was obtained.
- the diluted treatment baths were applied to unbleached cotton duck, weighing approximately 12 ounces per square yard, by immersing the fabric in the diluted treatment bath, squeezing between rubber rollers to leave in the fabric an amount equal to 80% of the Weight of the fiber, andthen drying on steam heated copper drums at 110 to 115 C. After drying, the samples were found to have gained about 45% in weight.
- Strips were cut 10 inches warpwise by 2 inches flllingwise and 10 inches fillingwise by 2 inches warpwise.
- the test strip was suspended vertically with the center of the lower end extending into the above flame of an inch. The strip was allowed to remain in the flame for 12 seconds; it was then removed, and the time that the sample continued to flame was noted. After all burning ceased, the length of char caused by flaming and glowing was measured. The charlength was determined by suspending a weight of 1 pound from one of the legs of the now V- shaped lower end of the sample, raising gently the end of the other leg to support both Weight and sample. thereby causing some tearing at the apex of the V, and then measuring the total depth of the V resulting from both burning and tear.

Description
Patented Dec. 24, 1946 V FLAMEPROOF ORGANIC FIBROUS MATE- RIAL AND COMPOSITION THEREFOR Osborne Coster Bacon, Penns Grove, N. J assignor to E. I. du Pont de Nemours & Company, Wilmington, Del., a corporation of Delaware No Drawing. Application December 24, 1943, Serial No. 515,586
11 Claims.
This invention relates to compositions suitable for producing a weather-resistant flameproof finish upon readily combustible fibrous material, such as paper, wood, leather and textiles of ani mal or vegetable origin. This invention further relates to novel, weather-resistant and flameproof fibrous materials produced by the use of said compositions.
For the purpose of tl'iisspeciflcation and the subjoined claims, a flanieproof fibrous material is defined as one which, if tested in a draft-free room by putting in contact with an initiating flame, will not continue to flame of its own accord for more than 5 seconds after removal of said initiating flame, and will not sustain combustion by afterglow beyond the charred area upon removal of said initiating flame.
It will be clear therefore that the material within the above definition may be actually consumed by fire as long as it is in contact with a flame, provided it will not continue to burn after the flame is removed.
Flameproof fibrous materials of the above qualities in gen 'al are not novel. It is old to coat pap-er and t "'iles with heavy metal oxides such as oxides of tin, lead, antimony, arsenic, bismuth, titanium and the like, and to decrease their combustibility thereby. It is also old to impregnate, coat, saturate, or otherwise surface-treat textile fabrics with heavy metal oxides and water-insoluble, chlorine-containing organic compounds having fire and waterproofing qualities. The latter are generally applied from an organic solvent, which sometimes also acts as a vehicle for the metallic oxide.
A full discussion of such chlorine-containing organic compounds is given in the text hereinbelow. All appear to be operative for the purpose in question by virtue of their property of liberating HCl when exposed to intense heat or light, Unfortunately, they retain this behavior, at a very slow rate of course, at ordinary temperatures and under ordinary sunlight as well. The liberated HCl attacks the fibrous material, and as a consequence the latter in due time develops the faulty quality of tendering, that is loss of tensile strength, especially when exposed to weather.
It is accordingly an object of this invention to produce flameproof fibrous material, for instance cellulosic textile material, which shall not develop appreciable tendering in outdoor use. A further object of this invention is to provide coating compositions for achieving the purpose composition of the above nature which is stable against separation of ingredients, and may be handled in commerce and stored for considerable periods for ultimate use by a consumer. Other and further important objects of this invention will appear as the description proceeds.
Now, according to this invention, the aforegoing objects are achieved by incorporating into the flameproofing coating composition, in addition to the metallic oxide and chlorinated organic compounds aforenoted, an anti-tendering agent which is the water-soluble reaction product of formaldehyde upon a mixture of a watersoluble alkaline-amine-proteinate and a reagent of the group which form water-soluble intermediate resins with formaldehyde, such as urea, adipamide, melamine and phenol. Typical re action products of this kind are described in U. S. Patent Nos. 2,262,770 and 2,262,771. In the latter patent aqueous formaldehyde is added to a solution of triethanolamine caseinate containing urea, the quantity of formaldehyde being sufllcient to react first with the solubilized protein and then with the urea. It is stated therein that the urea or its reaction product with formaldehyde exerts a solubilizing action upon the formaldehyde-protein reaction product, wherefore the entire composition is water-soluble and may be diluted considerably without precipitation. Incidentally, I have found that the said reaction products also act as dispersing agents for the other materials in the coating composition, and since they form an insoluble film upon heating above 100 0., they act further as binding agents for the other ingredients, especially pigments where such are employed. These factors enable me to apply the flameproofing composition to the fiber from an aqueous bath, thus obviating the need for organic solvents with their attendant fire hazard, toxicity and high cost. It also gives the entire composition stability against separation or settling, thus enabling my novel flameproof composition to be handled as an article of commerce and to be stored for indefinite periods. Furthermore, the added protein-resin reaction products overcome the sticky finish obtainable with some of the chlorinated organic materials, and they do not affect adversely the flexibility of the treated material at low temperatures.
For simplicity, I shall refer hereinafter to the above reaction product of formaldehyde upon a aforesaid. A still further object is to provide a mixture of an alkaline-amine proteinate and urea aerarea or its equivalent (phenol, melamine, etc.) as the protein-resin reaction product" or proteinresin composition, although it will be clear from the above discussion that the mass is an aqueous suspension containing water-soluble constituents and does not actually become converted into a water-insoluble resin until applied to the fiber and heated to 100 C. or over.
The protein material entering into the composition of the aforegoing protein-resin reaction products may be of either animal or vegetable origin; for example, casein, glue, soyabean protein or zein. All of these are characterized by the common property that they will react with ammonia, quaternary ammonium bases, 01 aliphatic amines, especially polyalkylol amines, to produce compounds soluble in water. I shall refer hereinafter to such compounds as solubilized proteins or as aikaline-amine-proteinates." The other component may be the reaction product of formaldehyde and an amide such as urea or adipamide, formaldehyde and an amine such as melamine, or formaldehyde and phenol.
The chlorine-containing compound employed for flame-proofing may be one of the group consisting of chlorinated paraifin wax, chlorinated fatty acids, chlorinated fish oil, chlorinated vegetable oil, chlorinated rubber, and chlorine-containing resins prepared by polymerizing compounds containing the vinylidine group HzC=C the said compounds having a chlorine content of from 20% to 80%. The flameproofing-property of the treated material generally increases with the chlorine content of the treating agent, although intermediate percentages of chlorine, say 40 to 65%, are preferred in most cases. The metal compound may be antimony trioxide, tetraoxide or pentoxide, tin oxides, bismuth oxides, arsenic oxides or any water-insoluble compound of these metals which will yield the oxide when heated, for instance the respective sulfides or the metals themselves.
In the customary practice with fiameprooflng compositions of the above type, the usual method 7 of application is to disperse the metal oxide in an organic solvent solution of the chlorine-containing compound and apply the mixture in one operation. Such a material corresponds to a solvent-carried paint.
According to my preferred mode of operation the anti-tendering agent of this invention, in other words, the aforesaid protein-resin reaction product, may be employed to produce aqueous suspensions of the aforegoing mixed flameproofing agents, wherein it acts both a a dispersing agent and as a protective bufier against the development of excessive concentrations of hydrogen chloride. However, if desired, the proteinresin buffering agent of this invention and the chlorinated organic fiameprooflng agent above discussed may be applied to the fabric separately, from separate organic solutions or aqueous suspensions.
As already noted, the protective agent of this .invention acts also as a dispersing agent, and as a binding agent for the other ingredients. However, additional, extraneous dispersing agents and binding agents may be added if desired. Likewise, fungicides may be added in the form of insoluble pigments or in the form of compounds soluble in the chlorinated organic agent; again, if desired, they may be added as a separate dispersion. Waterproofing materials may be similarly added when desired.
In addition to the foregoing, any of the customary special agents may be added to the coating composition to achieve special effects such as mildew resistance, rot-resistance, plasticity, coloring, etc. Particularly worthy of note as such auxiliary or special agents are: Salicylanilide (mildew resistance); zinc-dimethyl-dithiocarbamate (mildew and rot-resistance); inorganic coloring pigments such as lead chromate, iron oxides, chrome oxides, and organic pigments such as vat dyes, azo dyes and phthalocyanines; organic colors which are soluble in the chlorinated compound; parafiin wax (waterproofing); and plasticizers such as tricresyl phosphate and the butyl phthalates. Additional buffering agents, for instance water-insoluble calcium or magnesium carbonates may also be added.
The amount of protein-resin reaction product used is usually determined by the amount of dispersing agent needed and the flexibility of the applied film desired.
In general, the four fundamental ingredients of the present fiameprooflng compositions may be varied in amount as follows:
Per cent Protein-resin composition 5 to Metal compound 5 to 40 Chlorine-containing organic compound 10 to 40 Water 5 to 40 They may be applied to the fibrous material in concentrated form (up to 80% solids), or they may be diluted with water. The method of application may be dipping, brushing, spraying, or other means of coating or impregnating. The application to textile fabrics is generally carried out by immersion, squeezing and drying at elevated temperatures. The composition does not need to penetrate deeply to be effective. Good penetration of the interstices of materials such as cotton cloth is desirable when colored compositions are applied. Sufficient penetration is usually obtained when the material i absorbent such as bleached cotton while unbleached cotton is usually resistant to wetting by water and resists penetration.
Agents which lower the surface tension of water may be'added to assist wetting. Alcohols are the preferred wetting assistants, since they do not interfere with the effect of waterproofing agents where such are required. Ethyl alcohol is soluble in water while hexyl alcohol may be dispersed in the composition'or added as a separate dispersion.
The drying step in the? application of these products may be carried out at ordinary temperatures or at temperatures up to 300? F. 'or higher. The higher temperatures are preferred when fastness to water is required. However, considerable fastness to water may be obtained by drying at room temperature.
The compositions of this invention may be applied to any readily inflammable fibrous material such as wool, silk, cellulosic fabrics, ropes, sheets or articles of wood or paper to render them resistant to burning.
Treated materials such as cotton fabrics, paper, rope and wood require varying amounts of added finish to obtain a flameproofing eflect. Heavy weight fabrics can be proofed with less added finish per unit weight than light-weight fabric since the finish does not completely penetrate, and approximately the same amount is required for the same surface area.
Without limiting my invention, the following examples are given to illustrate my preferred mode of operation. Parts mentioned are by weight.

The diluted treatment baths were applied to unbleached cotton duck, weighing approximately 12 ounces per square yard, by immersing the fabric in the diluted treatment bath, squeezing between rubber rollers to leave in the fabric an amount equal to 80% of the Weight of the fiber, andthen drying on steam heated copper drums at 110 to 115 C. After drying, the samples were found to have gained about 45% in weight.
The resistance to burning of the samples thus prepared was compared with untreated material as follows:
Strips were cut 10 inches warpwise by 2 inches flllingwise and 10 inches fillingwise by 2 inches warpwise. A Bunsen burner, enclosed to exclude drafts, was adjusted to give a luminous flame 1 inches high.
The test strip was suspended vertically with the center of the lower end extending into the above flame of an inch. The strip was allowed to remain in the flame for 12 seconds; it was then removed, and the time that the sample continued to flame was noted. After all burning ceased, the length of char caused by flaming and glowing was measured. The charlength was determined by suspending a weight of 1 pound from one of the legs of the now V- shaped lower end of the sample, raising gently the end of the other leg to support both Weight and sample. thereby causing some tearing at the apex of the V, and then measuring the total depth of the V resulting from both burning and tear.
Resistance to burning was also determined after the treated fabric was subjected to a 24- hour leach by immersion in gently running water at 20-25 C.
The average values of 5 tests for each sample and treatment-bath were as follows:
Flaming time, both before leaching and after leaching 0 to 2 seconds.

The size of the burned area was taken as a measure of its resistance to burning.
Other samples of treated netting were leached 24 hours by immersion in gently running water at 25-30 C.
Still other examples of treated netting were exposed for 300 hours in a National weather unit.

To compare the protective action (against tendering of the treated materials) of my novel compositions of this invention against the above compositions of the prior art, the following additional tests were carried out.
Composition B: The same as Composition A, except that the quantity of xylol employed was reduced to 14 parts, and the mixture was emulsifled in water containing 10.0 parts of the proteinrcsin reaction-product obtained in Example 4.

Y #10 duck 50 3 in the details thereof may be practiced without departing from the spirit of this invention. Thus, in lieu of the chlorinated paraflin wax and antimony oxide employed in the majority of the above examples, any other combination of known,
practical, fire-resisting materials may be em ployed.
The essential fire-resisting materials of present-day practice are organic compounds containing 20 to 80% chlorine by weight and an oxide of the metals arsenic, antimony, bismuth or tin.
The chlorine-containing organic compounds include chlorinated paraflin wax, chlorinated fatty acids, chlorinated turpentine, chlorinated .paraflin oils, chlorinated vegetable oils, chlorinated rubber, vinyl chloride polymers, chlorinated vinyl chloride polymers, polyvinylidine chloride and other chlorine-containing organic compounds which are unstable at the ignition temperature of cellulosic materials.
It will be recognizedthat all the compounds indicated hereinabove are non-volatile at temperatures up to 300 F.
In all the above, the chlorinated organic compounds found most suitable in our invention are those which possess at least 40% 01' combined chlorine and which are adapted to liberate at least 50% of this combined chlorine in the form of hydrogen chloride upon being heated alone for five minutes at a temperature between 300 and 400 0.. which corresponds to the'average kindling point of untreated paper or'textile fiber.
Organic compounds of lower chlorine content, say 25 to 30%, may also be used, provided larger quantities of the compound are employed. The quantity of any given agent is in general selected so as to give a hydrogemchlorid equivalent not less than a predetermined minimum for any particular type of fibrous material.
According to this invention, the above materials are dispersed in water using a protein= formaldehyde-resin water-soluble reaction prodnot as the dispersing agent, which becomes a water-insoluble film when dried for a long time at ordinary temperatures or for shorter times at higher temperatures. The protein component may be casein, soyabean protein, glue, gelatin or other protein material which is normally rendered water soluble by the aid of alkaline agents and water-insoluble by the action of heat, acids or aldehydes. The alkaline solubilizing agent may be any water-soluble alkaline amine or quaternary ammonium base, although aliphatic amines (especially triethanolamine) are preferred. The most suitable aldehyde is formaldehyde and the most suitable resin base is urea. 'Oth'er resiniorming agents which could be used in lieu of urea are adipamide, succinamide, oxamide or other amides capable of forming water-soluble methylol derivatives which can be insolubilized by condensation to a resinous state. Phenol formaldehyde and melamine formaldehyde may also serve as the resin-forming agent. The essential requirement is that the dispersing-andfilm-forming agent shall prevent the degradation of cellulose treated with an unstable chlozine-containing organic compound. The degrading agent may be chlorine, hydrogen chloride,- hydrochloric acid or metallic chlorides formed from the metallic pigments used.
The compositions described in the examples may be prepared within a wide range of temperatures, say from 32 F. to 212F., although room temperature is preferred for convenience.
The order of addition of the various ingredients of these compositions is not critical except to maintain the optimum conditions for manufacturing, especially consistency, and to obtain a usable product. For example, it is logical to start with at least some of the water and the dispersing agent and then add the materials to be dispersed. It may also be desirable to combine part of the materials in one mix and part in another and then mix the two parts. For example, the metallic oxide may be dispersed along with calcium carbonate and coloring pigments and the dispersion mixed with another dispersion of the chlorine-containing organic material and optionally other ingredients. Where additional water-proofing or mildew-proofing properties are required in a composition, compatible dispersions of either or both of such agents may be added.
Compatible color dispersions may also be added s parately.
The pigments may be ,finely divided to begin with and be easily defiocculated, or it may be necessary to mill or grind the pigments in the vehicle. The pigments may be dispersed in the water phase directly or they may be ground in the chlorinated organic material and the mixture dispersed in the water phase. The water phase may even be dispersed in the oil phase (chlorinated organic compound) at some stage of preparation, although in the final stages, especially when diluted for use, the continuous phase is generally water since dilution tends to invert the water-in-oil" system.
The dispersed compositions may be prepared by any suitable means, such as by viscous milling. grinding in a paint or ink mill, or by high-speed agitation in a more fluid state.
The chlorine-containing material may be a solid dispersed as a pigment, or it may be a liquid at ordinary temperatures and be dispersed in the form of droplets,
The application of the compositions may be carried out under a wide range of conditions of temperature (32 F. to 212 F.), concentration (diluted with water or applied as prepared), and mechanical means of application, such as coating, spreading, brushing, immersion, spraying, etc. The composition may even be precipitated on material from a dilute bath by adding alum or other agents.
The impregnated material may be dried in any suitable manner, although greater durability to water is obtained at higher temperatures and longer periods of drying.
The protective protein-resin may be applied separately to the material to be treated and still be effective in preventing damage by chlorinecontaining materials applied to the same material.
The principal use of the novel compositions of this invention is to render textile fabrics resistant to burning. Materials of most interest are ducks for tents and paulins, and other fabrics such as netting, burlap and Osnaburg, awnings, upholstery, tobacco cloth, and similar materials which may be subjected to leaching by rain, water, exposure to sunlight, and weathering in general. Fabrics not to be exposed to leaching may also be advantageously treated. Treatments are effective on cotton, regenerated cellulose and woolfibers.
The compositions are also useful for treating paper articles, rope, cellulose sponge, padding, stufiing and insulating materials, such as straw and. wood shavings, wood, especially framework for houses and in attics and cellars of completed buildings.
The principal advantages of my novel comr positions are that they will not damage the treated material when exposed to light or heat under normal conditions of use, for instance, prolonged outdoor exposure; they do not contain toxic or inflammable materials; they are applicable from water; they are practically odorless, and the treated materials are non-tacky; the compositions are easily mixed with water, requiring no mechanical equipment for emulsification', and flexible materials remain flexible after treatment, even if subjected to extremely low temperature.
