| (54) | Non-water gelling alkyleneoxy substituted castor oil |
| (57) A non-water gelling alkylenoxy substituted castor oil having at least one alkyleneoxy
moiety represented as -(CH2CH2O)x(C3 or C4 alkyleneoxy constituent)yH wherein x is an integer of from 0 to about 45 and the
total -(CH2CH20) constituent is not more than about 90, and y is an integer of from about 0.3 to
about 10 and the total -(C3 or C4 alkyleneoxy constituent) is at least 1 and not more than about 30 is useful as a
lubricant for textile materials. Such is accomplished by contacting the textile material
with an aqueous admixture containing an effective amount of the alkyleneoxy substituted
castor oil so as to provide from about 0.5 to about 5 weight percent of the castor
oil constituent on the textile material. |
[0001] This invention relates to non-water gelling alkyleneoxy substituted castor oil compositions. In one aspect it relates to such alkyleneoxy substituted castor oil compositions wherein said alkyleneoxy moiety contains at least one C3 or C4 alkyleneoxy constituent. More particularly, the invention relates to non-water gelling alkyleneoxy substituted castor oil compositions and their use as textile lubricants in textile processing operations.
[0002] Ethoxylated castor oils have heretofore been employed as tufting lubricants for carpet backing and as a major component of producer finishes for man-made fibers. Problems have, nevertheless, been encountered in that such ethoxylated-castor oils have been difficult to dissolve or disperse in an aqueous medium because of their tendency to form gels of high viscosity when brought into contact with water. To overcome the before-mentioned gelling problems, the prior art has resorted to the use of heat and/or powerful agitation to break up and dissolve the gel to form an aqueous admixture.
[0003] It has further been recognized that higher alkylene oxides could be reacted with compounds containing active hydrogen in much the same manner as ethylene oxide. For example, alcohols, carboxylic acids, amines, phenols and the like have been subjected to propoxylation techniques, as well as ethoxylation techniques. In addition, copolymers of propylene oxide and ethylene oxide both random and block, have long been available commercially.
[0004] High temperature lubricants, for use in textile processing operations, such a gem disubstituted alicyclic compound in which the ring portion of the compound, e.g., a cycloaliphatic hydrocarbyl containing about 5 to about 7 carbon atoms, is substituted by a polyalkyleneoxy chain to thereby render same water-soluble or water-dispersible are disclosed in U. S. Patent Number 4,044,033. The polyalkyleneoxy chain, which is attached to a ring carbon through a functional group, such as a hydroxyl group, is stated to be an alkylene oxide, such as ethylene oxide or propylene oxide.
[0005] Thus, while numerous methods and compositions have heretofore been disclosed which contain alkyleneoxy moieties, such as ethylene oxide and/or propylene oxide, as well as uses for such compounds, the art has been void as to elimination of the gelling problem created when an ethoxylated castor oil composition is contacted with an aqueous medium, except for the use of heat and/or severe agitation.
[0006] Therefore, an object of the present invention is to provide an improved castor oil derivative useful as a textile lubricant which does not suffer from the problem of gel formation when contacted with an aqueous medium.
[0007] Another object of the invention is to provide an improved textile lubricant which is not reactive with the textile material and can be removed easily therefrom after processing of same.
[0008] These and other objects, advantages and features of the present invention will become apparent to those skilled in the art from a reading of the following detailed description.
[0009] According to the present invention, we have now discovered a substantially water-soluble or water-dispersible non-water gelling alkyleneoxy substituted castor oil composition having at least 1 alkyleneoxy moiety generally represented as
(̵CH2CH2O)̵x(C3 or C4 alkyleneoxy constituent)yH
wherein x is an integer of from 0 to about 45 and the total (̵CH2CH2O)̵ constituent in said alkyleneoxy substituted castor oil is not more than about 90, and y is an integer of from 0.3 to about 10 and the total iC3 or C4 alkyleneoxy constituent) in said alkyleneoxy substituted castor oil is at least 1 and not more than about 30.
[0010] Further according to the invention, we have discovered an improved method for reducing friction of a textile material and processing equipment during a textile processing operation which comprises contacting the textile material prior to and/or during processing with an aqueous admixture containing an effective amount of a non-water gelling alkyleneoxy substituted castor oil lubricant so as to provide from about 0.5 to about 5 weight percent of the lubricant on the textile material. More specifically, the alkyleneoxy substituted castor oil lubricant contains at least one alkyleneoxy moiety wherein the alkylene moiety is represented as
(̵CH2CH2O)̵x(C3 or C4 alkyleneoxy constituent)yH
wherein x is an integer of from 0 to about 45 and the total (̵CH2CH2O)̵ constituent is not more than about 90, and y is an integer of from about 0.3 to about 10 and the total fC3 or C4 alkyleneoxy constituent) in said lubricant is at least 1 and not more than about 30.
[0011] As previously indicated, the subject invention relates to a substantially water-soluble or water-dispersible non-water gelling alkyleneoxy substituted castor oil composition and to a method for using same wherein the alkyleneoxy moiety of such composition contains at least one alkyleneoxy moiety represented generally by the formula
(̵CH2CH2O)̵x(C3 or C4 alkyleneoxy constituent)yH
wherein x is an integer of from 0 to about 45 and the total (̵CH2CH20)̵ constituent in said alkyleneoxy substituted castor oil is not more than about 90, and y is an integer of from 0.3 to about 10 and the total (̵C3 or C4 alkyleneoxy constituent) in said alkyleneoxy substituted castor oil is at least 1 and not more than about 30.
[0012] It is important to note that in providing the desired non-water gelling properties to such an alkyleneoxy substituted castor oil composition that the alkyleneoxy moiety must contain at least one mole of the C3 or C4 alkyleneoxy constituent. As evident to those skilled in the art, what is meant by C3 or C4 alkyleneoxy constituent is to be understood to be propylene oxide, butylene oxide, including 1-butylene oxide as well as 2-butylene oxide. While the presence of either the C3 or C4 alkyleneoxy constituent in the alkyleneoxy moiety of the alkyleneoxy substituted castor oil composition will provide the desired non-water gelling properties to such composition, especially desirable results have been obtained wherein such C3 or C4 alkyleneoxy constituent is propylene oxide.
[0013] The term "non-water gelling" as used in the subject disclosure is to be understood to mean that upon admixing the alkyleneoxy substituted castor oil composition into an aqueous medium, a resulting admixture is formed which may either be an aqueous solution or an aqueous emulsion containing the desired composition. However, when an emulsion is formed, it is a very finely divided emulsion and thus, would be considered water-dispersible. The term "castor oil" is to be understood to be a generic term for a pale amber viscous liquid derived from the seed of the plants "Ricinus Cummunis" of the family "Eurphorbiaceae". Castor oil is one of the few naturally occurring glycerides that approaches being a pure compound since the fatty acid portion is nearly 90 % richinoleic. Thus, the average fatty acid composition of castor oil is 86% richinoleic, 8.5% oleic, 3.5% linoleic, 0.5 - 2% stearic, and 1-2% dihydroxy stearic acid. Thus, castor oil can generally be represented by the formula
Of course, as previously indicated, castor oil is understood to contain minor amounts of other components. However, the term "castor oil" as meant herein is well understood in the industry and can be readily obtained by those wishing to obtain such.
[0014] As previously stated, the substantially water-soluble or water-dispersible non-water gelling alkyleneoxy substituted castor oil composition for use in textile processing in accordance with the present invention contains at least one alkyleneoxy moiety which can be generally represented by the formula
(̵CH2CH2O)̵x(C3 or C4 alkyleneoxy constituent) H
wherein x and y are as previously defined.
[0015] Especially desirable results can be obtained when each alkyleneoxy moiety of the alkyleneoxy substituted castor oil composition contains from about 0 to about 15 moles of ethylene oxide, e.g. x is from 0 to about 15, and the total moles of such ethylene oxide in the molecule is not more than about 45 and when each alkyleneoxy moiety further contains from about 0.3 to about 10 moles of the C3 or C4 alkyleneoxy constituent, e.g., y is from about 0.3 to about 10, and the total number of moles of the C3 or C4 alkyleneoxy constituent in the alkyleneoxy substituted castor oil composition is from at least 1 to about 30. More specifically, the alkyleneoxy substituted castor oil composition can be typically illustrated by the following formula wherein x and y are as previously defined and z is an integer of 0 to 1.
wherein x and y are as previously defined and z is an integer of 0 or 1. As is to be understood, when z is the integer 0, the alkyleneoxy constituent of the alkyleneoxy moiety is a C3 alkyleneoxy constituent, e.g., propylene oxide, whereas when z is 1, such represents the alkyleneoxy constituent being a butylene oxide.
[0016] The non-water gelling alkyleneoxy substituted castor oil composition of the present invention can be prepared by employing ethoxylation and propoxylation or butoxylation procedures which are well known in the art. To illustrate such preparation the following is set forth. However, it is to be understood that many other methods of preparation can be envisioned and thus the subject invention is to not be limited only to the method of prepa-ration as set forth hereinafter.
[0017] In preparing the novel compositions of the present invention, one generally will first ethoxylate the castor oil. Once the desired level of ethoxylation has been achieved, the resulting product, e.g., the ethoxylated castor oil is then propoxylated and/or butoxylated with an effective amount of propylene oxide or butylene oxide to insure that at least one mole of propylene oxide or butylene oxide per mole of castor oil is reacted therewith. However, one could readily envision a single alkoxylation process in which two or more alkyleneoxy monomers are mixed prior to alkoxylation. It is interesting to note that we have found that if one desires to obtain the desired non-gelling water-soluble or water-dispersible alkylene oxide substituted castor oil composition of the present invention, one must provide at least one mole of the propylene oxide or butylene per mole of castor oil onto the molecule.
[0018] In carrying out the desired ethoxylation it is important to insure that the reactor is in a clean and dry condition. Thereafter, the castor oil is charged into the reactor along with a minor amount of sodium hydroxide flake. Agitation is then commenced within the reactor and vacuum stripping in the magnitude of 25 to 28 inches is likewise commenced. Thereafter, the reactor and contents therein is heated to a temperature of from about 100°C to about 150°C while maintaining a vacuum on the reactor for a period of time after the reactants within the reactor have reached the desired temperature. Thereafter, the vacuum on the reactor is broken with nitrogen and the reactor is purged, preferably about two times, followed by venting. However, the pressure on the reactor should be maintained up to about 150 psi. Once the reactor has been purged with nitrogen, vented, and the pressure established, the temperature of the reactants is then increased to about 145-150°C at which time the desired amount of ethylene oxide is introduced into the reactor. Once the ethylene oxide has been completely added, the reactor is maintained at such reaction conditions for a period of time to allow substantially complete reaction of the ethylene oxide with the castor oil. Thereafter, the reactor is vacuum stripped to remove any unreactive ethylene oxide and then repressured with an inert gas, such as with nitrogen, for the subsequent propoxylation or butoxylation of the ethoxylated castor oil.
[0019] To propoxylate or butoxylate the resulting ethoxylated castor oil the following procedure can be employed. The temperature of the reactor is preferably reduced to a temperature of from about 110 to 140 and the propylene oxide or butylene oxide is added to the reactor in a predetermined amount. The pressure on the reactor should gradually increase upon the addition of the propylene oxide or butylene oxide. Generally a pressure of less than about 60 psi is maintained in the reactor during the propoxylation or butoxylation step. The reaction of propylene oxide or butylene oxide will generally be somewhat more sluggish than that of the ethylene oxide particularly where the concentration of propylene oxide or butylene oxide is low. The reaction is held at reaction temperature for about one hour after all the propylene oxide or butylene oxide has been added to the reactor. Thereafter, the product is vacuum stripped to remove any unreacted constituents from the reactor. It is advisable at this time to submit a sample of the resulting product for analysis to see if the desired amount of propoxylation or butoxylation has occurred. If additional propoxylation or butoxylation is determined to be necessary, such can be readily obtained by the addition of a propylene oxide or butylene oxide charge to the reactor and the maintaining of the reactor in the before-mentioned reaction conditions.
[0020] Once the proper degree of ethoxylation and propoxylation or butoxylation has been achieved, the product is again stripped well to remove any residual propylene oxide or butylene oxide. Thereafter, the resulting ethoxylated-propoxylated or butyoxylated castor oil composition is then cooled under nitrogen to a temperature of less than about 100°C. If required, the product can be bleached to the color specification using any suitable bleaching agent, such as 30% hydrogen peroxide. The product can then be recovered from the reactor and be pH adjusted if desired.
[0021] The compositions so prepared, e.g., the non-water gelling alkyleneoxy substituted castor oil composition of the present invention in which the total amount of the C3 or C4 alkyleneoxy constituent is present in the molecule in at least one mole can thereafter be employed as a lubricant in the textile processing operations, such as tufting, texturing, spinning, or the like, such operations being well known in the textile processing art. Generally, by application of an aqueous admixture containing an effective amount of the substantially water-soluble or water-dispersible non-water gelling alkyleneoxy substituted castor oil composition as described hereinbefore, one can substantially reduce the friction of a textile material and processing equipment during the textile processing operations. Any suitable means can be employed to apply the alkyleneoxy substituted castor oil composition to the textile material, such as by passing the textile material, e.g., fibers, yarns, and the like, through a bath containing effective amounts of alkyleneoxy substituted castor oil composition, or by passing the textile material over a saturated roll containing the aqueous admixture of such castor oil constituent, or by direct spraying of the textile material with same. The amount of the non-water gelling alkyleneoxy substituted castor oil lubricant which is applied to the textile material, e.g., the fibers, yarns, and the like, can vary widely but will generally be from about 0.5 to about 5 weight percent. Likewise, the amount of the alkyleneoxy substituted castor oil composition present in the aqueous admixture can vary widely, such being due to a large extent upon the particular make-up of the textile material, as well as its wet pick-up characteristics. Generally, however, we have found that when the aqueous admixture contains from about 0.5 percent to about 30 weight percent of the alkyleneoxy substituted castor oil composition that the desired amount of such lubricant, e.g., from about 0.5 to about 5 weight percent, can be applied to substantially any textile material. Further, depending upon the particular operation through which the textile material is being passed, the aqueous admixture containing the alkyleneoxy substituted castor oil lubricant can be applied prior to and/or during such processing steps, the particular mode of application being left to the prerogative of those skilled in the art and their particular processing techniques.
