Definitions
- This invention relates to a process for the treatment of fibrous materials and more specifically to animprove'd process and composition whereby textiles and other fibrous cellulosic materials may be rendered highly and permanently resistant to attack by fungus and bacteria.
- fungicidal or bactericidal agent such as a solution of 8-hydroxyquinoline, ortho-phenyl-phenol or chlorophenyl-phenol, and subsequently dried
- the fabric will attain some degree of resistance to fungicidal and. bactericidal action.
- subsequent wetting or laundering of the fabric thus treated tends to remove the fungicidal or bactericidal agent and thereby to reduce drastically the resistance of the fabric to fungi and bacteria.
- a fabric treated by the two-bath method hereinbefore described and subsequently dried contains soluble salts which leach out when the cloth is subsequently laundered or subjected to weathering conditions, impairing the. residual protection against fungus and bacteria.
- the two-bath method requires additional equipment and an increased cost for the application of the treatment.
- the best-known fungicidal agents embodying heavy metal salts of substances such as oxyquinoline are too insoluble in water and in other liquid media suitable for fabric impregnation to provide adequate concentration of the agent in a single bath for proper treatment of the fabric.
- One of the objects of the present invention is to provide a process whereby textiles, cordage, paper, wood and other cellulosic or-part cellulosic materials may be impregnated with sufficient amount of relatively insoluble fungicidal agents in a single immersion to render the subsequently dried cellulosic material permanently and effectively resistant to the action of fungus and bacteria.
- a further object is to provide a novel fungus and bacteria-proofing composition.
- Another object is to provide a novel fungicidal and bactericidal agent.
- the improved fungicide-proofing composition of the present invention comprises a water-in-oil emulsion containing in the oil phase thereof a a relatively water-insoluble fungicidal agent, such as copper B-hydroxyquinoline, a modified alkyd resin havin a relatively high ratio of fatty acid residue to phthalic anhydride residue, and a mixture of chlorinated diphenyls.
- a part (or all of the modified alkyd resin may be present in the composition in the form of an ammonium soap.
- Suitable fungicidal agents for the purpose of the present invention are copper S-hydroxyquindline, copper 5,7-dibromo-B-hydroxyquinoline, copper 5,7-dichloro-8-hydroxyquinoline, 5,7-dibrominated hydroxyquinoline, 5,7-dichloro-8-hydroxyquinoline and copper pentachlorophenate.
- Other metallic salts may be employed in place of the copper salts, for example. zinc, cadmium, aluminum or calcium salts.
- the copper salts are much to be preferred, however, since they are by far the most effective from the standpoint of insolubility and permanency when incorporated in the cellulosic material.

Description
Patented Dec. 21, 1948 FUNGUS-PROOFING COMPOSITION Paul George Benignus, Belleville, Ill., assignor to Monsanto Chemical Company, St. Louis, Mo., a corporation of Delaware No Drawing. Application August 11, 1944, Serial No. 549,139
11 Claims. (01. 260-22) This invention relates to a process for the treatment of fibrous materials and more specifically to animprove'd process and composition whereby textiles and other fibrous cellulosic materials may be rendered highly and permanently resistant to attack by fungus and bacteria.
When cellulosic materials such as fabrics are immersed in a bath containing a fungicidal or bactericidal agent such as a solution of 8-hydroxyquinoline, ortho-phenyl-phenol or chlorophenyl-phenol, and subsequently dried, the fabric will attain some degree of resistance to fungicidal and. bactericidal action. However, subsequent wetting or laundering of the fabric thus treated tends to remove the fungicidal or bactericidal agent and thereby to reduce drastically the resistance of the fabric to fungi and bacteria. In order to fix the fungicidal agent on the fabric, it has been proposed to form the metallic salt of the agent within the interstices of the fabric. Since the metallic salts of many of the fungicidal agents such as 8-hydroxyquinoline and the chicrophenols are relatively insoluble in most media for treating fabrics, it has been proposed to employ a method whereby after immersion in a solution of a fungicidal agent of this type, the fabric is drained and subsequently passed through a solution of water-soluble metal salt such as calcium, magnesium or other alkaline earth acetates, zinc, aluminum copper, cadmium, mercury or other heavy metal acetates or nitrates whereby the metal salt of the fungicidal agent is precipitated on the fabric. This method of fixing the fungicidal agent on the fabric has certain dis-' advantages. For example, a fabric treated by the two-bath method hereinbefore described and subsequently dried contains soluble salts which leach out when the cloth is subsequently laundered or subjected to weathering conditions, impairing the. residual protection against fungus and bacteria. Moreover, the two-bath method requires additional equipment and an increased cost for the application of the treatment. In additionfmany of the best-known fungicidal agents embodying heavy metal salts of substances such as oxyquinoline are too insoluble in water and in other liquid media suitable for fabric impregnation to provide adequate concentration of the agent in a single bath for proper treatment of the fabric.
One of the objects of the present invention is to provide a process whereby textiles, cordage, paper, wood and other cellulosic or-part cellulosic materials may be impregnated with sufficient amount of relatively insoluble fungicidal agents in a single immersion to render the subsequently dried cellulosic material permanently and effectively resistant to the action of fungus and bacteria.
A further object is to provide a novel fungus and bacteria-proofing composition.
Another object is to provide a novel fungicidal and bactericidal agent.
Other objects will become apparent from the following description and examples.
The improved fungicide-proofing composition of the present invention comprises a water-in-oil emulsion containing in the oil phase thereof a a relatively water-insoluble fungicidal agent, such as copper B-hydroxyquinoline, a modified alkyd resin havin a relatively high ratio of fatty acid residue to phthalic anhydride residue, and a mixture of chlorinated diphenyls. As a further embodiment of the invention, a part (or all of the modified alkyd resin may be present in the composition in the form of an ammonium soap.
Suitable fungicidal agents for the purpose of the present invention are copper S-hydroxyquindline, copper 5,7-dibromo-B-hydroxyquinoline, copper 5,7-dichloro-8-hydroxyquinoline, 5,7-dibrominated hydroxyquinoline, 5,7-dichloro-8-hydroxyquinoline and copper pentachlorophenate. Other metallic salts may be employed in place of the copper salts, for example. zinc, cadmium, aluminum or calcium salts. The copper salts are much to be preferred, however, since they are by far the most effective from the standpoint of insolubility and permanency when incorporated in the cellulosic material.
Modified alkyd resins suitable for the purpose of the present invention are those which are prepared from fatty oils and fatty acids, such as linseed oil and linseed oil fatty acids, phthalic anhydride and glycerol. Other fatty oilsor acids or mixtures thereof, such as a mixture of linseed oil,
dehydrated castor oil and linseed oil fatty acids, a mixture of linseed oil and dehydrated castor oil, or a mixture of linseed oil, soya bean oil and soya bean fatty acids, may be employed in. the preparation of the resin. Likewise, other polyhydroxy alcohols, such as pentaerythritol, may be employed in place of glycerol. Maleic or fumaric acids may be employed in place of part or all of the phthalic anhydride. It is understood that these substitutions give rise in alterations to the properties of the resins. However, as explained hereinbefore', those resins which are soluble in mineral spirits and which emulsify mineral spirits are the resins contemplated as components of the composition of the present invention. Likewise, ammonium soaps formed by the addition of ammonia to the modified alkyd resins which fall in this category are also contemplated as components of the composition of the present invention. Suitable modified alkyd resins for the purpose of the present invention are. those which contain, for example, from 20-40% by weight of phthalic anhydride residue and which are soluble in mineral spirits and serve as emulsifying agentsfor mineral spirits.
The chlorinated diphenyls suitable as components of the composition of this invention are the mixtures of chlorinated diphenyls obtained by chlorinating diphenyl and which mixtures contain from 20-68% of chlorine. Also included are those chlorinated diphenyls which contain in addition various proportions of chlorinated terphenyls. Some of these mixtures are liquid at room temperature and others may be melted, for example, on heated metal rolls to become liquids at temperatures rangingirom 30-140".C.
The composition of the present invention may also contain a flame-retarding agent such as antimony pentoxide in amounts ranging from 2-10% of the weight of the composition, in which event the quantity of chlorinated diphenyls may be increased to an amount in the range of 10-25% of the weight of the composition.
The emulsion composition of the present invention may contain any desired proportions of water phase to oil phase in the range of 1:4 to 4:1. A desirable proportion is that of 50 parts of water and 50 parts of oil. The quantity of modified alkyd resin employed in the composition may be varied over a wide range, for example, from 2% or less to 10% or more, based on the emulsion composition. The quantity of ammonia employed to form a soap with the residual acidic constituents of the modified alkyd resins depends on the extent to which soap formation is desired and may range from part tototal consumption of the acidity available in the resin for this purpose. The quantity of chlorinated diphenyl mixture which may be employed in the composition may be varied over a wide range, for example, from 3% or less to 25% or more. The quantity of fungicidal agent, such as copper 8-hydroxyqulnoline, may be varied over a wide range, depending upon the particular fungicidal agent selected, the
. amount of the agent which is absorbed from the composition in the treatment of a particular type of cellulosic substance to be treated and the amount of the fungicidal agent which is desired on the cellulosic substance after the treatment. Desirable quantities of fungicidal agent in general of the composition of the present invention may range from or less to or more.
In employing the fungus-proofing composition of the present invention, cellulosic materials, such as textiles, cordage, paper or Wood, are immersed in the composition to impregnate the cellulosic substance and then are dried. The impregnation may be accomplished in any desired manner, for example, by immersion in a vessel containing the composition, with or without the aid of squeeze rolls, either as a continuous operation or as a batch process. For some types of application, the composition may be brushed on the fabric, paper or wood article. Likewise, the drying operation may be accomplished in any desired manner, for example, by exposing the respective sur-- faces of the treated article simultaneously or successively to air streams which may be at room temperature or at higher temperatures below the charring point of the cellulosic materials. Textiles, cordage, paper and wood treated with the composition of the present invention are found to be highly resistant to the action of fungus and bacteria. Moreover, the resistance is characterized by a high degree of permanency even when the treated cellulosic material is subjected to severe weathering or, in the application to textiles and cordage, to successive launderings.
The fungicidal and bactericidal composition of the present invention may be formed in any manner desired. A preferred method is that comprising blending the fungicidal agent, the modified alkyd resin and the chlorinated diphenyl on metal rolls, with the application of heat if necessary, until a smooth fluid paste is formed. The paste is then dispersed in mineral spirits. If the ammonium soap of the alkyd resin is to be formed, the necessary quantity of ammonia may be added to the blend on the rolls, or to the mineral spirits dispersion of the blend. Water is then added to the mixture and the mixture is agitated to form the emulsion, for example, by passing the mixture through a colloid mill. While the permanency of many of the fungicidal agents of the type hereinbefore described is substantially enhanced by application to the cellulosic material by means of the composition of the present invention, very'outstandlng results in this respect are obtained when the fungicidal agent in the composition is 5,7-dibromo-8-hydroxyquinoline. copper 5,7-dibromo-8-hydroxyquinoline, 5,7-dichloro-8-hydroxyquinoline, copper dichloro-8- hydroxyquinoline or copper S-hydroxyquinoline. These substances in particular are representative of the various fungicidal and bactericidal agents of the type contemplated in the composition of the present invention.
While the alkyd resin in the composition of the present invention aids in the placement and retention of the fungicidal agent within the interstices of the cellulosic material. it also imparts to the treated cellulosic material a certain degree of water repellency. However, it is desirable to treat the cellulosic substance further with a water repellent in order to attain a high degree of Water repellency in the fabric treated with the fungicidal composition. It is one of the novel features of the present invention that the composition of the present invention is compatible with a wide variety of water-proofing emulsion compositions and water-proofing components. There water proofing compositions and components may be acidic, neutral or alkaline in character. More over, the application to cellulosic materials of the composition of the present invention containing a water-repellent emulsion has been found to enhance the degree of permanency of resist-- ance of the cellulosic material to the action of molds and particularly when the treated cellulosic materials are subjected to soil burial tests.
Typical water-repellent compositions which may be incorporated in the composition of the present invention are those which comprise aqueous suspensions of waxes andsoapsresinous hydrocarbon-soluble condensation products, such as dimethylol urea resins, dimethylol urea ether resins, tetramethylol melamine resins, tetramethylol melamine ether resins, either alone or in the presence of higher fatty acid soaps, fatty acid amine soaps, fatty acid amides and N-acylated alkylene polyamides. The quantity of water-repellent composition or of water-repellent components to be added to the composition of the present invention is determined on the basis of the amount of water-repellent component of the composition desired on the treated material.
the percentage pick-up of such water-repellent components by the material to be treated, and the amount of water-repellent components desired on a particular cellulosic material after the treatment. When the composition of the present invention contains a water repellent, the cellulosic material after treatment is heated in order to set the water-repellent components on the cellulosic material. Temperatures in the range of -170 C. have been found suitable for this glycerine.

In place of copper pentachlorophenate, any other substantially water-insoluble salt of pentachlorophenol may be employed, for example, the calcium, barium, lead, zinc, aluminum, mercury or cadmium salts of pentachlorophenol. are distinguished from the halogenated 8-hydroxyquinoline derivatives and copper salts thereof, and also copper 8-hydroxyquinoline in that the pentachlorophenates appear to produce fungicidal action by the hydrolysis of the salts in the presence of moisture, whereas the halogenated 8-hydroxyquino1ine derivatives and the copper salts thereof appear to produce fungicidal action by mere contact of the agent with the mold organisms. It is of interest also that the copper salts of the halogenated and unhalogenated B-hydroxyquinoline appear from ex- These pentachlorophenates perimental observations to be the only metal 1 salts of these substances which inhibit mold growth completely when applied in the composition of the present invention.
Portions of specimens of cellulosic substances, including wood, paper, textiles and cordage treated with the compositions described in Examples I to IV were exposed to the action of various molds. The treated textile specimens were tested against the organisms C'haetonium globasum, Aspergillis niger, Penicillium sp., Metarrhizium sp. by the method described in the Corps of Engineers, U. S. Army, Tentative Specification No. T1452 A, entitled Processing fabrics, cordage and threads for mildew-proofing. dated Janu ry 15, 1943, paragraphs F 3-a (3) to 3-a (8), inclusive. There was no evidence of fungus growth on the treated specimens. Untreated specimens exposed under similar conditions were heavily attacked by the various species of fungus. Other portions of the textile and cordage specimen were laundered for 40 minutes in soap water at 100 0., rinsed free of soap, dried and exposed to the same molds. There was no evidence of fungus growth on the laundered and exposed specimens. Other portions of the textile and cordage specimens were leached in running water for 200 hours, dried and exposed to the molds. Additional specimens were buried in moist soil rich in acidic humus for a period of several weeks. Upon inspection, the exposed, treated specimens were found to be substantially free of fungus growth.
