Description:
BACKGROUND OF THE INVENTION 
     The present invention relates to a fiber treatment compositions and to a method of making fiber treatment compositions. More particularly, the present invention relates to organofunctional silicone emulsions and their ability to impart beneficial characteristics such as slickness, softness, compression resistance and water repellency to substrates such as fibers and fabrics that is not possible without the use of the compositions and method of the instant invention. 
     It is generally known to treat textile fibers with organopolysiloxanes to impart a variety of valuable properties to the fibers, such as water repellency, softness, lubricity, antipilling, good laundry and dry cleaning durability, and the like. The use of organopolysiloxanes to achieve such properties is now well established but there continues to be a need to improve these and other desirable properties of the fibers, especially the antipilling properties of the fabrics made from treated fibers. In particular, there has existed a desire to improve the properties of the fibers while improving the processes by which the organopolysiloxane compositions are applied to the fibers, and in this regard, the need to speed up the processing of the fibers is the most urgently needed. 
     Typical of prior art compositions and processes used for achieving the desirable processing and end use properties are those curable compositions disclosed in U.S. Pat. No. 3,876,459, issued Apr. 8, 1975 to Burrill in which there is set forth compositions obtained by mixing polydiorganosiloxanes having terminal silicon-bonded hydroxyl radicals with an organosilane (or partial hydrolysates thereof) of the formula RSiR&#39;n(X)3-n, in which R is a monovalent radical containing at least two amine groups, R&#39; is an alkyl or aryl group, X is an alkoxy radical and n is 0 or 1. 
     The polydiorganosiloxanes are linear or substantially linear siloxane polymers having terminal silicon-bonded hydroxyl radicals and an average degree of substitution on silicon of 1.9 to 2.0 wherein the substituents are generally methyl radicals. The siloxane polymers have an average molecular weight of at least 750 with the preferred molecular weight being in the range of 20,000 to 90,000. The cure mechanism appears to arise through the reaction of the hydrolyzable groups on the silane with the silanol groups of the siloxane polymer, usually under the influence of a catalyst, and at elevated temperatures. 
     Burrill discloses in U.S. Pat. No. 4,177,176, issued Dec. 4, 1979, an additional composition for use in treating fibrous materials. The composition is disclosed as containing a polydiorganosiloxane having a molecular weight of at least 2500 and terminal --OX groups in which X is hydrogen, lower alkyl or alkoxyalkyl groups with the proviso that there also be present at least two substituents in the polydiorganosiloxanes which are amine groups. There is also present an organosiloxane having at least three silicon-bonded hydrogen atoms, the curing mechanism being based on the reaction of the silicon-bonded hydrogen atoms with the silanol end blocks of the polydiorganosiloxane polymers under the influence of a catalyst. 
     Also included in the prior art is the disclosure of Burrill, et al. in U.S. Pat. No. 4,098,701, issued Jul. 4, 1978 in which the inventors set forth yet; another curable polysiloxane composition which has been found useful for treating fibers which comprises a polydiorganosiloxane in which at least two siliconbonded substituents contain at least two amino groups, a siloxane having silicon-bonded hydrogen atoms, and a siloxane curing catalyst. A study of the &#39;701 patent shows that &#34;siloxane curing catalyst&#34; is used in the sense that non-siloxane containing organofunctional compounds are used to cure siloxane curable materials, and that siloxane compositions that function as catalysts is not intended. 
     Also, there is disclosed in the prior art the curable system described by Spyropolous et al, in European patent application publication 0 358 329 wherein microemulsions are described in which the oil phase comprises a reaction product of an organosilicon compound having amino groups and an organosilicon compound having epoxy groups, wherein the reaction product has at least one amino group and two silicon-bonded --OR groups, and a method for making the microemulsions. The organosilicon compound having at least one silicon-bonded substituent of the general formula --R&#39;NHR&#34;, wherein R&#39; is a divalent hydrocarbon group having up to 8 carbon atoms, and R&#34; denotes hydrogen, an alkyl group or a group of the general formula --RBH2, and (B) an organosilicon compound having at least one substituent of the general formula --R&#39;--Y, wherein R&#39; is as defined for those above, and Y denotes an epoxy group containing moiety, whereby the molar ratio of amino groups in (A) to epoxy groups (B) is greater than 1/1, there being present in the reaction product at least two silicon-bonded --OR groups, wherein R denotes an alkyl,, aryl, alkoxyalkyl, alkoxyaryl or aryloxyalkyl groups having up to 8 carbon atoms. 
     Chen et al., in U.S. Pat. No. 5,063,260 discloses curable silicone compositions which impart beneficial characteristics to fibers, the compositions comprising an amino organofunctional substantially linear polydiorganosiloxane polymer, a blend of an epoxy organofunctional substantially linear polydiorganosiloxane polymer and a carboxylic acid organofunctional substantially linear polydiorganosiloxane polymer, and an aminoorganosilane. Chen et al. also discloses a process for the treatment of animal, cellulosic, and synthetic fibers by applying the composition described above the fiber and thereafter curing the composition on the fiber to obtain a treated fiber. 
     Yang in European Patent Application No. 0415254 discloses stable aqueous emulsion compositions containing an aminofunctional polyorganosiloxane containing at least two amino functionalized groups per molecule, one or more silanes and optionally a hydroxy terminated polydiorganosiloxane, textiles treated with the emulsion compositions, and processes for the preparation of the emulsion compositions. Revis in U.S. Pat. Nos. 4,954,401, 4,954,597, and 5,082,735 discloses a coating for a paper substrate produced by contacting and forming a mixture of an allyl ester with at least one methylhydrogensiloxane in the presence of a Group VIII metal catalyst, coating the mixture on the substrate, and heating the mixture of the allyl ester, the methylhydrogensiloxane, the substrate, and the Group VIII metal catalyst in the presence of ambient moisture until the methylhydrogensiloxane becomes cured and cross-linked. 
     Bunge in U.S. Pat. No. 4,954,554 discloses aqueous emulsions compositions consisting essentially of a curable silicone composition comprising organopolysiloxane having silicon-bonded hydroxyl radicals or silicon-bonded olefinic radicals, an organohydrogenpolysiloxane and a curing catalyst, a polyvinylalcohol emulsifyingagent having a degree of hydrolysis of 90 mole percent or more, and water. These compositions are disclosed as having improved gloss and/or water-repellency and/or adhesive release. 
     Other silicone emulsions containing olefinic siloxanes have been disclosed. For example, Hara et al. in U.S. Pat. Nos. 5,095,067 and 5,104,927 teaches a release silicone emulsion composition comprising 100 parts by weight of a specific organovinylpolysiloxane, from 1 to 50 parts by weight of a specific organohydrogensiloxane, from 0.5 to 5 parts of a platinum catalyst having a viscosity of 10 centistokes or less at 25° C., from 1.5 to 15 parts by weight of a nonionic emulsifying agent having an average HLB of from 10 to 20, and a Ph of 6.5 or less, and water. These compositions are disclosed as having good pot life, curability and that the cured film has good release properties and residual adhesive properties of adhesives. 
     However, none of the references hereinabove disclose a one component fiber treating emulsion comprising an unsaturated acetate, at least one organohydrogensiloxane, a metal catalyst, an organosilicon compound, and one or more surfactants or solvents which imparts beneficial characteristics to textile fibers.

These novel rhodium catalyst complexes are generally compositions comprising a rhodium catalyst, an unsaturated acetate such as linallyl acetate, and alcohols having having 3 or more carbon atoms including diols, furans having at least one OH group per molecule, and pyrans having at least one OH group per molecule. 
     The amount of Group VIII metal catalyst, Component (C), that are used in the compositions of this invention is not narrowly limited and can be readily determined by one skilled in the art by routine experimentation.

     The present invention further relates to a method of treating a substrate, the method comprising the steps of (I) mixing: (A) an unsaturated acetate, (B) at least one organohydrogensiloxane, (C) a metal catalyst, (D) an organosilicon compound having an average of at least one group per molecule selected from the group consisting of hydroxy groups, carboxy groups, ester groups, amino groups, acetoxy groups, sulfo groups, alkoxy groups, acrylate groups, epoxy groups, fluoro groups, ether groups, olefinic hydrocarbon or halohydrocarbon radicals having from 2 to 20 carbon atoms, and mixtures thereof, and (E) a dispersant selected from the group consisting of one or more surfactants and one or more solvents, (II) applying the mixture from (I) to a substrate, and (III) heating the substrate. Components (A), (B), (C), (D), and (E) are as delineated above including preferred amounts and embodiments thereof. 
     The present invention also relates to a method of making a fiber treatment composition comprising (I) mixing (A) an unsaturated acetate, (B) at least one organohydrogensiloxane, (C) a metal catalyst, (D) an organosilicon compound having an average of at least one group per molecule selected from the group consisting of hydroxy groups, carboxy groups, ester groups, amino groups, acetoxy groups, sulfo groups, alkoxy groups, acrylate groups, epoxy groups, fluoro groups, ether groups, olefinic hydrocarbon or halohydrocarbon radicals having from 2 to 20 carbon atoms, and mixtures thereof, and (E) a dispersant selected from the group consisting of one or more surfactants and one or more solvents. Again, Components (A), (B), (C), (D), and (E) are as delineated above including preferred amounts and embodiments thereof. 
     The present invention further relates to a method of making a fiber treatment composition comprising: (I) mixing: (i) an organosilicon compound having an average of at least one group per molecule selected from the group consisting of hydroxy groups, carboxy groups, ester groups, amino groups, acetoxy groups, sulfo groups, alkoxy groups, acrylate groups, epoxy groups, fluoro groups, ether groups, olefinic hydrocarbon or halohydrocarbon radicals having from 2 to 20 carbon atoms, and mixtures thereof, and (ii) a dispersant selected from the group consisting of one or more surfactants and one or more solvents; (II) adding to the mixture of (I) a mixture of: (iii) an unsaturated acetate, (iv) at least one organohydrogensiloxane, and (v) a metal catalyst. The mixture of Step (II) can be emulsified prior to adding the mixture of (II) to the mixture of (I) . Again, Components (A), (B), (C), (D), and the surfactants are as delineated above including preferred amounts and embodiments thereof. 
     The compositions comprising components (A), (B), (C), (D), and optionally any surfactants or solvents (E) may be applied to the fibers by employing any suitable application technique, for example by padding or spraying, or from a bath. For purposes of this invention, the compositions can be applied from a solvent, but is preferred that the compositions be applied from an aqueous medium, for example, an aqueous emulsion. Thus, any organic solvent can be employed to prepare the solvent-based compositions, it being understood that those solvents that are easily volatilized at temperatures of from room temperatures to less than 100° C. are preferred, for example, such solvents may include methylene chloride, acetonitrile, toluene, xylene, white spirits, chlorinated hydrocarbons, and the like. The treating solutions can be prepared by merely mixing the components together with the solvent. The concentration of the treating solution will depend on the desired level of application of siloxane to the fiber, and on the method of application employed, but it is believed by the inventors herein that the most effective amount of the composition should be in the range such that the fiber (or fabric) picks up the silicone composition at about 0.05% to 10% on the weight of the fiber or fabric. According to the instant inventive method of treatment, the fibers usually in the form of tow, or knitted or woven fabrics, are immersed in an aqueous emulsion of the compositions whereby the composition becomes selectively deposited on the fibers. The deposition of the composition on the fibers may also be expedited by increasing the temperatures of the aqueous emulsion, temperatures in the range of from 20° to 60° C. being generally preferred. 
     Preparation of the aqueous emulsions can be carried out by any conventional technique. The compositions of this can be prepared by homogeneously mixing Components (A), (B), (C), and (D) and any optional components in any order. Thus it is possible to mix all components in one mixing step immediately prior to using the fiber treatment compositions of the present invention. Most preferably (A), (B), and (C) are emulsified and then (D) is emulsified and the two emulsions thereafter combined. The emulsions of the present invention may be macroemulsions or microemulsions and may also contain optional ingredients, for example antifreeze additives, preservatives, biocides, organic softeners, antistatic agents, dyes and flame retardants. Preferred preservatives include Kathon® LX (5-chloro-2-methyl-4-isothiazolin-3-one from Rohm and Haas, Philadelphia, Pa. 19106), Giv-gard® DXN (6-acetoxy-2,4-dimethyl-m-dioxane from Givaudan Corp., Clifton N.J. 07014), Tektamer® A.D. (from Calgon Corp., Pittsburgh, Pa. 152300), Nuosept® 91,95 (from Huls America, Inc., Piscataway, N.J. 08854), Germaben®  (diazolidinyl urea and parabens from Sutton Laboratories, Chatham, N.J. 07928), Proxel® (from ICI Americas Inc., Wilmington, Del. 19897), methyl paraben, propyl paraben, sorbic acid, benzoic acid, and lauricidin. 
     Following the application of the siloxane composition to the substrate, the siloxane is then cured. Preferably, curing is expedited by exposing the treated fibers to elevated temperatures, preferably from 50° to 200° C. 
     The compositions of this invention can be employed for the treatment of substrates such as animal fibers such as wool, cellulosic fibers such as cotton, and synthetic fibers such as nylon, polyester and acrylic fibers, or blends of these materials, for example, polyester/cotton blends, and may also be used in the treatment of leather, paper, and gypsum board. The fibers may be treated in any form, for example as knitted and woven fabrics and as piece goods. They may also be treated as agglomerations of random fibers as in filling materials for pillows and the like such as fiberfil. 
     The composition of components (A), (B), (C), and (D) should be used at about 0.05 to 25 weight percent in the final bath for exhaust method applications, and about 5 gm/l to 80 gm/l in a padding method of application, and about 5 gm/1 to 600 gm/l for a spraying application. The compositions employed in this process are particularly suitable for application to the fibers or fabrics from an aqueous carrier. The compositions can be made highly substantive to the fibers, that is they can be made to deposit selectively on such fibers when applied thereto as aqueous emulsions. Such a property renders the compositions particularly suited for aqueous batch treatment by an exhaustion procedure, such exhaustion procedures being known to those skilled in the art. The compositions of the instant invention are new and novel and provide a fast cure and wide cure temperature ranges for curing them on fibers or fabrics compared to the compositions of the prior art, having a temperature cure range of from 50° C. to 200° C. Further, the fibers have superior slickness and no oily feeling after cure. The compositions of the instant invention provide consistent performance, good bath life of more than 24 hours at 40° C., have good laundry and dry cleaning durability, and have very good suitability for application by spraying. 
     Fiber Slickness was tested by using a DuPont® unslickened fiberfil product, i.e. Hollofil® T-808, for the evaluation of slickness imparted by the application of the silicone emulsion of the present invention. A piece of Hollofil® T-808 is soaked in the diluted emulsion of interest and then passed through a roller to obtain 100% wet-pickup, i.e., the weight of the finished fiberfil is twice that of the unfinished fiberfil. After drying at room temperature, the finished sample is heated at 175° C. for 2-25 minutes. Thus prepared, the finished fiberfil usually contains approximately the same silicone level as that of the emulsion of interest. 
     The slickness of fiberfil is measured by staple pad friction which is determined from the force required to pull a certain weight over a fiberfil staple pad. The staple pad friction is defined as the ratio of the force over the applied weight. A 10 pound weight was used in the friction measurement of this invention. A typical instrument set-up includes a friction table which is mounted on the crosshead of an Instron tensile tester. The friction table and the base of the weight are covered with Emery Paper #320 from the 3M Company so that there is little relative movement between the staple pad and the weight or the table. Essentially all of the movement is a result of fibers sliding across each other. The weight is attached to a stainless steel wire which runs through a pulley mounted at the base of the Instron tester. The other end of the stainless steel wire is tied to the loadcell of the Instron tester. 
     Following are examples illustrating the compositions and methods of the present invention. In the examples hereinbelow, THF denotes tetrahydrofuran, THFA denotes tetrahydrofurfuryl alcohol, and TPRh denotes (Ph 3  P)RhCl 3  (tris-(triphenylphosphine)rhodium chloride).

     EXAMPLES 1-10 
     In order to illustrate the effectiveness of the compositions of the present invention the following tests were conducted. Two catalysts were prepared, a rhodium catalyst and a microencapsulated curing catalyst. A .03 molar rhodium catalyst solution was prepared by dissolving 1 gram of RhCl 3  •6H 2  O (rhodium trichloride hexahydrate) or TPRh in 120 grams of THF, THFA, or linallyl acetate. A 10% and 1% platinum catalyst solution was prepared by dissolving 10 grams and 1 gram, respectively, of a platinum catalyst prepared according to Example 3 of U.S. Pat. No. 5,194,460 in 90 grams and 99 grams, respectively, of linallyl acetate. 
     Into a glass container was added the acetate material. With gentle mixing using a round edge three blade turbine mixing impeller, one of the catalyst solutions prepared above was added to the acetate and mixed until the mixture was homogenous. Next, a mixture of 100 grams of a trimethylsilyl terminated polymethylhydrogensiloxane having a viscosity of 30 centistokes at a temperature of 25° C. and having the formula Me 3  SiO(MeHSiO) 70  SiMe 3  and an amount of an organosilicon compound (denoted in Table I hereinbelow) was added to the mixture and stirred gently until the mixture was again homogenous. This was followed by adding about 1.78 grams of a polyoxyethylene lauryl ether surfactant or a methylene chloride solvent (in Example 7 a solvent was substituted for the surfactant), and about 38 grams of water containing up to about 0.22 grams of a preservative (sorbic acid) to the mixture. Mixing was then resumed at medium speed for 20 to 30 minutes. The mixture was then processed through a high shear device to produce the emulsions of the instant invention. The particle sizes of the emulsions ranged from 0.7 to 3.0 microns and the pH of the emulsions ranged from 3.0 to 4.5. 
     A relative ranking from 1 to 10 was established using known commercial finishes based upon slickness values obtained using the Staple Pad Friction frictional test described hereinabove. No finish was given a ranking of 1, the commercial finish was given a ranking of 6, and a premium finish was given a ranking of 10. The amount of organosilicon compound, organosilicon compound type, the amount of linallyl acetate, the amount of catalyst, catalyst type, the time it took each sample to cure in minutes (min.), and the performance of each example are reported in Table I hereinbelow.

     A second emulsion was prepared by mixing about 2 weight percent of an aqueous solution of an intermediately hydrolyzed PVA having a degree of hydrolysis of 96% and a 4% aqueous solution viscosity of 30 centipoise (cP) at 25° C., a surfactant, and 51 weight percent of water. Next, about 40 weight percent of a dimethylvinylsiloxy-terminated polydimethylsiloxane having a viscosity of 450 cP and about 1% of a platinum-containing catalyst were mixed and stirred. Next, the PVA-surfactant mixture was added to the siloxane mixture and stirred. This mixture was then processed through a colloid mill and 7 weight percent of water containing a biocide was added to form an emulsion. 
     Next, 7.5 grams of the first emulsion, 7.5 grams of the second emulsion, and 85 grams of water were mixed together and the resulting emulsion stirred. 
     This silicone emulsion cured in 10 minutes and the sample was ranked according to the staple pad friction procedure delineated hereinabove. The silicone emulsion attained a rating of between 5 and 6. Thus the compositions of the instant invention outperformed the silicone emulsion previously described in the art. 
     It should be apparent from the foregoing that many other variations and modifications may be made in the compounds, compositions and methods described herein without departing substantially from the essential features and concepts of the present invention. Accordingly it should be clearly understood that the forms of the invention described herein are exemplary only and are not intended as limitations on the scope of the present invention as defined in the appended claims.
