Definitions
- the present invention relates to polyamide textile substrates treated with stain-resistant compositions comprising water-soluble or water-dispersible maleic anhydride/ alpha-olefin polymers, and processes for their synthesis.
- the substrates of this invention possess stain-resistance but do not suffer from yellowing to the extent that some previously known materials do.
- Polyamide substrates such as nylon carpeting, upholstery fabric and the like, are subject to staining by a variety of agents, e.g., foods and beverages.
- An especially troublesome staining agent is FD&C Red Dye No. 40, commonly found in soft drink preparations.
- Different types of treatments have been proposed to deal with staining problems.
- One approach is to apply a highly fluorinated polymer to the substrate.
- Another is to use a composition containing a sulfonated phenol-formaldehyde condensation product.
- Liss et al. in U.S. Patent No. 4,963,409, disclose stain-resistant synthetic polyamide textile substrates having deposited on them sulfonated phenol-formaldehyde polymeric condensation products.
- sulfonated phenol-formaldehyde condenation products are themselves subject to discoloration; commonly they turn yellow.
- Yellowing problems are described by W. H. Hemmpel in a March 19, 1982 article in America's Textiles , entitled Reversible Yellowing Not Finisher's Fault. Hemmpel attributes yellowing to exposure of a phenol-based finish to nitrogen oxides and/or ultraviolet radiation. To deal with the yellowing problem, the condensation products were modified by Liss et al.
- the modified condensation products were dissolved in a hydroxy-containing solvent, such as ethylene glycol prior to there being applied to the textile substrate.
- Allen et al. in U.S. Patent 3,835,071, disclose rug shampoo compositions which upon drying leave very brittle, non-tacky residues which are easily removed when dry.
- the compositions comprise water-soluble metal, ammonium or amine salt of a styrenemaleic anhydride copolymer, or its half ester, and a detergent.
- Water-soluble metal salts of Group II and the alkali metals (particularly magnesium and sodium) are preferred and ammonium salts are most preferred by Allen et al.
- Fitzgerald et al. in EP-A 0 329 899, disclose the usefulness of aqueous solutions of hydrolyzed vinylaromatic/maleic anhydride copolymers in the treatment of textiles to render them resistant to staining.
- the preferred copolymer of Fitzgerald et al. is a hydrolyzed styrene/maleic anhydride copolymer.
- Fitzgerald et al. disclose that the monoalkyl ester of their maleic anhydride/vinyl aromatic polymer was ineffective as a stain-resist.
- maleic anhydride/alpha-olefin polymers are known.
- EP-A 306,992 published 15 March 1989 discloses maleic anhydride/-1-alkene (C 4-30 ) polymers.
- Florjanczyk et al. in Terpolymerization of Maleic Anhydride With Vinyl Monomers, J. Polymer SCI., Part A: Polym. Chem., 27 (12), 4099-108 disclose terpolymers of maleic anhydride with (i) 1-hexene, propylene, isobutylene, styrene, isoprene or 1,3-butadiene, and (ii) methyl methacrylate, methyl acrylate or acrylonitrile.
- EP-A-0 177 972 discloses an aqueous fabric finishing composition containing a solubilised copolymer of a 1-alkene having at least 10 carbon atoms and maleic anhydride.
- EP-A-0 332 342 discloses imparting stain resistance to fibrous polyamide using aqueous compositions of copolymers of methacylic acid with a monocarboxylic acid or a mono olefin.
- the present invention is based on the finding that polyamide fibrous substrates treated with specified water-soluble or water-dispersible maleic anhydride/alpha-olefin polymers have stain-resistance.
- prior art materials known to be useful as stain-blockers were sulfonated phenol-formaldehyde condensates (excepting those of Fitzgerald et al, supra).
- Finding a non-sulfonated material, such as the water-soluble or water-dispersible alpha-olefin/maleic anhydride polymers of this invention, to be useful for this purpose was unexpected.
- the present invention provides a polyamide fibrous substrate having deposited on it an amount of a composition effective to impart stain-resistance to said substrate comprising a water-soluble or water-dispersible alphaolefin/maleic anhydride polymer or a mixture of said polymers, wherein said polymer contains from 0.7 to 1.3 polymer units derived from one or more alpha-olefin monomers per polymer unit derived from maleic anhydride and has been hydrolysed to the corresponding free acid or salt thereof or converted to a C 1-4 alkyl monoester, the alpha-olefin content of said polymer comprising between (a) 100 and 80 mol percent of at least one 1-alkene containing 4 to 8 carbon atoms or terminally unsaturated diene containing 4 to 18 carbon atoms and (b) 0 to 20 mol percent of at least one 1-alkene containing 3 or 10 to 18 carbon atoms.
- the present invention relates to the use of certain water-soluble or water-dispersible maleic anhydride/alpha-olefin polymers, or mixtures of the same, as stain-resists for fibrous polyamides.
- a variety of linear and branched chain alpha-olefins can be used for the purposes of this invention.
- Useful alpha-olefins are dienes containing 4 to 18 carbon atoms, such as butadiene, chloroprene, isoprene, and 2-methyl-1,5-hexadiene; 1-alkenes containing 4 to 8 carbon atoms, such as isobutylene, 1-butene, 1-hexene, 1-octene, with isobutylene being most preferred.
- a part of the alpha-olefins can be replaced by other monomers, e.g. up to 50 wt% of vinyl acetate, vinyl chloride, vinylidine chloride, vinyl sulfides, N-vinyl pyrrolidone, acrylonitrile, acrylamide, as well as mixtures of the same.
- a part (1-75%) of the maleic anhydride can be replaced by maleimide, N-alkyl(C 1-4 ) maleimides, N-phenyl-maleimide, fumaric acid, itaconic acid, citraconic acid, aconitic acid, crotonic acid, cinnamic acid, alkyl(C 1-18 ) esters of the foregoing acids, cycloalkyl(C 3-8 ) esters of the foregoing acids, sulfated castor oil, or the like.
- At least 95 wt% of the maleic anhydride co- or terpolymers have a number average molecular weight of in the range between about 700 and 200,000, preferrably between about 1000 and 100,000.
- water-soluble or water-dispersible interpolymers i.e. copolymers, terpolymers, and the like
- maleic anhydride and one or more 1-alkenes having 4 to 8 carbon atoms particularly isobutylene, 1-hexene and 1-octene
- polyamide substrates e.g. carpeting
- Copolymers of maleic anhydride with propylene were found by the inventor to be less effective as stain-resists on such substrates than were interpolymers of maleic anhydride and 1-alkenes containing 4 to 8 carbon atoms.
- copolymers of maleic anhydride and at least one olefin selected from ethylene and 1-alkenes having 10 to 24 carbon atoms impart no detectable stain-resistance to such substrates.
- the maleic anhydride polymers useful in the present invention can be prepared according to methods well-known in the art.
- the maleic anhydride polymers thus obtained are hydrolyzed to the free acid or their salts by reaction with water or alkali, or they are reacted with C 1-4 alkyl alcohol to provide polymeric alpha-olefin/maleic acid monoesters, which have stainblocking properties.
- the hydrolyzed maleic anhydride polymer, or the monoester polymer should be sufficiently water-soluble that uniform application to a fibrous polyamide surface can be achieved at an appropriate acidity.
- applications using water dispersions of the polymer mixed with a suitable surfactant may be used to impart stain-resistance.
- stain-resists of the present invention can blend with other known stain-resists, such as phenol-formaldehyde condensation products as disclosed in U.S. Patents 4,833,009 and 4,965,325; methacrylic acid polymers disclosed in U.S. Patent No. 4,937,123; or hydrolized polymers of maleic anhydride and one or more ethylenically unsaturated aromatic compounds described by Fitzgerald et al., supra.
- stain-resists of the present invention can blend with other known stain-resists, such as phenol-formaldehyde condensation products as disclosed in U.S. Patents 4,833,009 and 4,965,325; methacrylic acid polymers disclosed in U.S. Patent No. 4,937,123; or hydrolized polymers of maleic anhydride and one or more ethylenically unsaturated aromatic compounds described by Fitzgerald et al., supra.
- the polymers suitable for the purposes of this invention contain between from 0.7 to 1.3 polymer units derived from one or more alpha-olefin monomers per polymer unit derived from maleic anhydride.
- the alpha-olefin content of the polymers of this invention comprise between (a) 100 and 80 mol% of at least one 1-alkene containing 4 to 8 carbon atoms or terminally unsaturated diene containing 4 to 18 carbon atoms and (b) 0 to 20 mol% of at least one 1-alkene containing 3, or 10 to 18, carbon atoms.
- Polymers containing about one polymer unit derived from one or more olefin monomers per polymer unit derived from maleic anhydride are most effective in imparting stain resistance to textile substrates.
- the molecular weight of the polymers useful in the invention does not appear to be a limitation so long as the polymers are water-soluble or water-dispersible.
- hydrolyzed isobutylene/maleic anhydride copolymers having number average molecular weights between about 6000 and 100,000 impart good stain-resistance to polyamide substrates.
- water-soluble isobutylene/maleic anhydride copolymers having number average molecular weights between about 6000 and 100,000 remained in solution in water at 60°C.
- the polymers suitable for the purposes of this invention can be prepared by hydrolyzing the maleic anhydride/olefin polymers according to methods well-known in the art. For example, they can be hydrolyzed to the free acid or their salts by reaction with water or alkali.
- the maleic anhydride polymer should be sufficiently water-soluble that uniform application to a fiber surface can be achieved at an appropiate acidity.
- applications using dispersions of the polymers with suitable surfactants may be used to impart stain-resistance.
- olefin/maleic anhydride polymers disclosed herein are used in treating polyamide textile substrates. They can be effectively applied to polyamide fibrous substrates by a wide variety of methods known to those skilled in the art, such as:
- the quantities of the polymers disclosed herein which are applied to the textile substrate are amounts effective in imparting stain-resistance to the substrate. Those amounts can be varied widely; in general, one can use between 1 and 5% by weight of them based on the weight of the textile substrate, usually 2.5% by weight or less.
- the polymers can be applied, as is common in the art, at pHs ranging between about 2 and 7. However, more effective exhaust deposition can be obtained at a pH as low as 1.5. When the latter low pH is used, the preferred level of application to the textile substrate is about 2.5% by weight, based on the weight of the textile substrate. In an embodiment, a pH between about 2 and 3 is used.
- stainblocking is obtained if the polymers are applied to the textile substrate at either 20°C followed by heat treatment at a temperature in the range between about 50 and 150°C for about 1 to 60 minutes, or applied at temperatures in the range between about 40 and 95°C for about 1 to 60 minutes. For example, at a pH between about 2 and 3, a temperature between about 70 and 90°C is preferred. However, stain-blocking can be obtained when application is effected even at that of cold tap water (10-15°C).
- the polymers disclosed herein can also be applied in-place to polyamide carpeting which has already been installed in a dwelling place, office or other locale. They can be applied as a simple aqueous preparation or in the form of aqueous shampoo preparation, with or without one or more polyfluoro-organic oil-, water-, and/or soil-repellent materials. They may be applied at the levels described above, at temperatures described, and at a pH between about 1 and 12, preferably between about 2 and 9.
- a 500 ml autoclave was charged with 40 g of maleic anhydride (0.408 mole), 300 ml of ethylbenzene and 4.3 g of 70 wt% of benzoyl peroxide. It was closed, vented twice with propylene and heated under stirring to 70 °C. The autoclave was then pressurized with propylene to 1379 kPa (200 psi). After agitation for 3 hours at 70°C, a solution of 2.7 g of 70 wt% benzoyl peroxide in 10 ml of ethylbenzene was blown into the reactor and the reaction was continued at 70°C for another 14 hours. The vessel was then cooled and vented.
- the maleic anhydride/propylene copolymer product in form of a dispersion, was discharged and filtered giving 46.7 g of a white powder having a number average molecular weight, by gel permeation chromatography (GPC), of 2150.
- GPC gel permeation chromatography
- a portion of the solid copolymer (10 g) was hydrolyzed at 80-95°C in the presence of 82.5 g deionized water, 6.7 g 30 wt% sodium hydroxide and 2 drops of a 1% solution of benzyltriethylammonium chloride resulting after about 1 to 2 hours in a clear solution containing 10 wt% of a water-soluble maleic anhydride/propylene copolymer.
- An isobutylene/maleic anhydride copolymer (50 parts) having a number average molecular weight (GPC) of 32,000, commercially available from Kuraray Co. (Japan) as "Isobam”-04, was reacted under agitation with methanol (50 parts) at reflux temperature (about 65°C) for 23 hours. Excess methanol was then removed at reduced pressure (20 mm Hg) at 70-90°C to give the isobutylene/maleic acid monomethyl ester which was then dissolved at room temperature in dilute ammonium hydroxide ( 2.5 parts of ammonia in 356 parts of water) to give a 14.5 wt % solution.
- GPC number average molecular weight
- Nylon fiber was treated with 1.2 wt% or 2.4 wt% stain resist at a goods-to-liquor ratio of 1:32 at a pH of 2.0 or 2.35 for 45 minutes at 80 or 95°C.
- the fiber was then washed, air-dried and exposed at room temperature to a dye solution consisting of 0.2 g of FD&C Red Dye No. 40 and 3.2 g of citric acid in 1 liter of deionized water at a goods-to-liquor ratio of 1:40. After approximately 65 hours, the dye adsorbed onto the fiber was determined at a wavelength of 498-502 nm by comparing the absorbance with that of the Control.
