Definitions
- Antistatic floor covering and textile products of enhanced durability to cleaning and reduced migration tendency are produced by applying between two polymeric covering layers disposed beneath the textile or floor covering wear layer an antistatic composition consisting essentially of a mixture of (a) an organic antistatic agent,
- a humectant which may be either a nonionic humectant, such as glycerin, or an ionic humectant such as calcium chloride, and
- humectant when said humectant is a nonionic humectant, an electrolyte such as calcium chloride or sodium chloride and applying a polymeric backing coating over the antistatic layer, whereby the antistatic layer is disposed between the two polymeric covering layers.
- electrolyte such as calcium chloride or sodium chloride
- This invention is directed to antistatic textile products and floor coverings of textile and non-textile compositions. Most specifically the invention relates to an antistatic carpet structure which has a fibrous layer, a primary backing thereunder, a latex pre-coat layer thereover, an antistatic-conductive coating, and a polymeric backing.
- Conventional floor coverings are capable of generating and transferring substantial charges of static electricity. These charges of static electricity are created when persons in contact with the dielectric wear layer, such as the fibrous layer of the carpet move over said fibrous layer. The charge per se is created by the movement of dielectric shoe components which are in contact with the dielectric wear layer. These charges are then transferred to the wearer of the shoe. When the wearer subsequently becomes grounded, the accumulated charge discharges through that part of the individuals body which is in contact with the ground. This discharge procedure can result in severe discomfort to the individual. The above described problem can be eliminated if the charges of static electricity can be dispersed throughout the floor covering structure, and subsequently dissipated into the surrounding environment.
- An ancillary problem is also the fire hazard attendant to the flammability of the carpet structure due to migration of the antistatic composition up through the textile structure thus causing a stiffening of the pile with resultant stand-up to the flame; and the fact that said migration causes a loss in the effectiveness and durability of the product when such a treated carpet is washed.
- the floor covering and textile struc ture of this invention disperses quickly and thoroughly, charges of static electricity without the need of specific conducting fibers.
- the structure of this invention bleeds off charges of static electricity.
- the antistatic composition of this invention is incorporated between two polymeric backings in contrast to the vast majority of the prior art antistatic compositions which are not compatible nor effective for such a sandwiching and isolation between polymeric backings. Because of this incompatibility, carpets specifically, which are treated with these prior art antistatic compositions could not utilize most polymeric backings, and particularly the commonly used natural latex backing. In contrast, the antistatic coating of this composition as utilized herein is compatible with natural latex backings, adhesives and most other polymeric coating compounds.
- floor covering as used herein is intended to include linoleum petroleum product floorings, vinyl and asbestos sheet and tile floor covering, polyurethane and polyolefin floorings and the like and the invention is directed thereto as well.
- an antistatic textile and floor covering product comprising (1) a Wear layer, such as a fibrous textile layer,
- an antistatic coating composition layer disposed beneath said pre-coat layer, said antistatic layer consisting essentially of a mixture of (a) an organic antistatic agent, (b) a humectant selected from the group of ionic and monionic humectants, and
- the subject antistatic floor covering and textile structure is illustrated as a carpet in the single figure of the accompanying drawing.
- the structure, of the floor covering, such as a carpet 2 has a conventional wear layer, such as a fibrous layer 4 which can be woven, tufted, knitted, flocked or other structure usual in carpets.
- This fibrous layer can be composed of any of the usual textile fibers or blends or mixtures thereof employed in carpet manufacture, such as wool, polyamides (e.g. nylon 66 and nylon 6), cotton, polyolefins (particularly polypropylene), acrylics, modacrylics, polyesters, etc.
- the fibrous layer 4 is woven in, tufted through, or in some other manner affixed to a backing layer 5, usually a woven fabric of cotton or jute, although other fibers and types of construction can be employed for the backing thereof.
- the basic carpet structure may be any carpet manufacture, such as the well known tufted, Brussels, Wilton, Axminster, chenille, velvet, flocked, knit etc.
- the underside of the fibrous or pile layer 4 with its primary backing to which the fiber forming pile is afirxed or through which it is tufted, etc. is coated with a pre-coat latex layer 3, comprised of any of the conventional latices, this layer 3 is then coated with an antistatic coating 6 which provides a uniform continuous layer thereover.
- the antistatic coating 6 is effective without being in contact with the backing and the ends of the fibers forming the pile.
- the amount of material applied as such antistatic coating should be sufficient to substantially over the pre-coat layer 3. Normally from .01 to 20 ounces per square yard and preferably from 2.0 to 10.0 ounces per square yard of the antistatic coating is applied.
- the antistatic coating composition employed for the antistatic coating layer 6 ideally comprises a mixture of a textile antistatic agent and to 50 parts by weight of humectant. There may also be employed from 0.1 to about 1 part by weight of a nonionic or cationic type wetting agent to assist the dispersing of the antistatic composition. It is also preferable to incorporate in the coating composition from about 0.1 to about 1 part by weight of an electrolyte particularly if the humectant employed is nonionic in character or is only weakly ionic, i.e. has a relatively low dissociation constant.
- the antistatic coating 6 is preferably applied in the form of an aqueous solution or dispersion, although other solvents or liquid dispersing mediums may be employed if desired and in the case of aqueous solutions or dispersions, volatile water-soluble solvents, such as lower aliphatic alcohols of 1 to 4 carbon atoms, acetone and the like, may be included to facilitate drying of the antistatic layer following its application.
- volatile water-soluble solvents such as lower aliphatic alcohols of 1 to 4 carbon atoms, acetone and the like, may be included to facilitate drying of the antistatic layer following its application.
- Examples of satisfactory pre-coat latex layers 3 which may be applied to the underside of the primary backing 5 include filled or unfilled coatings of acrylic latexes, vinyl acetate latexes, styrene-butadiene latexes (preferably carboxylated), natural latex, vinyl chloride and vinylidene chloride interpolymers and the like with plasticizing monomers, such as butyl acrylate and including ethylenevinyl chloride copolymers and the like.
- Satisfactory adhesive coats include all of the above, but in general styrene-butadiene latexes are preferred.
- a polymeric backing layer 8 is then applied to the carpet and forms an essential element of the carpet structure of this application.
- This polymeric backing layer is preferably applied in the form of an aqueous dispersion (latex) and is preferably a known compound natural rubber latex or compounded carboxylated butadiene-styrene rubber-latex, commonly employed as latex backing for carpetings, although other polymeric coatings, such as polystyrene, vinylidene chloride, polyacrylates, butadiene-styrene rubbers and the like may be employed both herein and as the pre-coat layer 3.
- the two polymeric coatings 3 and 8 serve the function of holding the antistatic coating layer 6 in place yet without interferring with electric charge dissipation. Charges of static electricity built up in the pile 4 are dispersed throughout the entire carpet area by antistatic layer 6 and subsequently bled off into the ground or atmosphere. In order to assist bleeding such charges to the ground, the polymeric coating 3 and 8 may have incorporated therein a material such as as carbon black or any agent which will lower the dielectric properties of the polymeric layers.
- compositions for the antistatic coating layer 6 of the carpet structure of the present invention are disclosed in US. Pat. 3,519,561 of Andrew J. Kelly and Robert C. Britt entitled Antistatic Composition and Process. Particularly preferred are those antistatic compositions disclosed in said patent in which potassium formate is employed as humectant since it has been found that not only is potassium formate particularly effective as a humectant in such coating compositions, but compositions containing the same are compatible with the latex backing and specifically overcomes premature coagulation or gelling of latex backing based on natural compounded rubber, thus not interfering with good bonding of the latex coated with the carpet backing.
- the antistatic coatings containing calcium chloride are incompatible with certain known latex coatings which have been used as carpet bac kings in that they cause premature coagulation or gelling of the latex with resultant poor adhesion of the latex to the carpet backing so that in the case of loosely woven or tufted carpets the latex does not function satisfactorily to hold the tufts in place.
- antistatic layers based on the antistatic compositions of the above mentioned patent are particularly preferred, it will be understood that one may employ any antistatic layer based on any known antistatic material suitable for textiles which will disperse charges of static electricity.
- antistatic material suitable for textiles which will disperse charges of static electricity.
- Such agents are normally nitrogen containing or carboxylic containing organic antistatic agents and as examples thereof may be mentioned the following compounds:
- Amine oxides or quaternar ammonium salts of vinyl pyrrolidone dirnethylamino-ethylmethacrylate copolymers are examples of vinyl pyrrolidone dirnethylamino-ethylmethacrylate copolymers.
- Vinyl pyrrolidone acrylamine copolymers such as a copolymer of vinyl pyrrolidone and 25% acrylamide.
- Ethoquad C/l2polyoxyethylated quaternary ammonium salt Ethoquad C/l2polyoxyethylated quaternary ammonium salt.
- Phosphonamide sulfonate of an alcohol ethoxylate i.e., a product of the formula whereinR represents the hydrocarbon residue of an 5 alkanol (such as Alfol 1412) and n represents an integer of 8 to 20.
- Esters .of phosphoric acid and ethoxylated aliphatic alcohol such as the phosphate esters of lauryl alcohol condensed with 4 moles of ethylene oxide or of dodecyl alcohol condensed with about 2 moles of ethylene oxide
- Polyglycol 4000 Sucrose octa-acetate
- Polyethoxy amides of stearic and oleic acid Methyl diethanolamine ethoxylate Ethoxylated 2,3,7,9-tetramethyl-5-decyne-4,7-diol Polyoxyethylenemono-oleate Lauryl trimethyl ammonium chloride Undecylimidazolone Lauryl dimethylbenzyl ammonium chloride Polyoxyethyl stearyl ammonium chloride Oleic-monoisoproparol amide Vinyl acetate/styrene/ acrylic acid polymers Ethoxylated diamines Long chain amine oxides Hydroxybutyramides Quaternized poly
- the phosphate esters of the type referred to in said patents may be prepared by reacting one mole of P with 2 to 4.5 moles of a nonionic surface active agent having the molecular configuration of a condensation product of at least one mole of ethylene oxide with one mole of a compound containing at least 6 carbon atoms and a reactive hydrogen atom under substantially anhydrous conditions and at a temperature below about 110 C.
- the process does not require the use of an excess of the hydroxylic organic compound (in this instance the defined nonionic surface active agent), in order to bring the P 0 into solution.
- Substantially no tertiary phosphate ester is formed and little or no P 0 remains in the composition.
- the product may in some instances contain some unreacted nonionic surface active agent which for certain uses is actually advantageous.
- Lighter colored or substantially colorless products are obtained when the phosphation reaction is carried out in the presence of a small or catalytic amount of a phosphorus-containing compound selected from the group consisting of hypophosphorous acid, salts of hypophosphorous acid, phosphorous acid, and salts and esters of phosphorous acid.
- the process comprises reacting one mole of P 0 with 2 to 4.5 moles of a nonionic surface active agent having the molecular configuration of a condensation product of at least one mole of ethylene oxide with one mole of a compound containing at least 6 carbon atoms and a reactive hydrogen atom, under substantially anhydrous conditions and at a temperature below about 110 C. in the presence of a small amount of one or a 6 mixture of the aforementioned hypophosphorous or phosphorous acid compounds.
- Products resulting from the use thereof generally have VCS (varnish color scale, Gardner scale, standards of 1933) values of at least one less than products of the same process carried out in the absence of the hypophosphorous or phosphorous acid compound. Products having a VCS color of about 1 or less are thus made possible, as compared with VCS colors of from about 2 to 7 or more for products produced without the aid of the present invention. Further, the products have been found to resist discolorations or darkening even after storage for three to six months.
- nonionic surface active agents employed as reactants are well known in the art and are disclosed along with suitable methods for their preparation in numerous patents and other publications. In general, they may be obtained by condensing a polyglycol ether containing the required number of alkenoxy groups or an alkylene oxide such as propylene oxide, butylene oxide, or preferably ethylene oxide, with an organic compound containing at least 6 carbon atoms and a reactive hydrogen atom.
- a reactive hydrogen atom there may be mentioned alcohols, phenols, thiols, primary and secondary amines, and carboxylic and sulfonie acids, and their amides.
- alkylene oxide or equivalent condensed with the reactive chain will depend primarily upon the particular compound with which it is condensed. As a convenient rule of thumb, an amount of alkylene oxide or equivalent should be employed which Will result in a condensation product containing about 20 to by weight of combined alkylene oxide. However, the optimum amount of alkylene oxide for attainment of the desired by hydrophobic hydrophilic balance may be readily determined in any particular case by preliminary test and routine experimentation.
- the nonionic surface active agents having the molecular configuration of a condensation product of at least one mole of an alkylene oxide, preferably ethylene oxide, with one mole of a compound containing at least 6 carbon atoms and a reactive hydrogen atom are preferably polyoxyalkylene derivatives of alkylated and polyalkylated phenols, multi-branched chain primary aliphatic alcohols having the molecular configuration of an alcohol produced by the 0x0 process from a polyolefin of at least 7 carbon atoms, and straight chain aliphatic alcohols of at least 10 carbon atoms.
- E.O means ethylene oxide and the number preceding same refers to the number of moles thereof reactedwith one mole of the given reactive hydrogen-containing compound.
- the P 0 is preferably added gradually, with vigorous agitation to the nonionic surface active agent in liquid form. If the latter agent is a solid at room temperature, it should be heated to above its melting point. Addition of the nonionic surface active agent to the P 0 is inadvisable since this has been found to result in the formation of tar and the like and to prevent the reaction from proceeding to completion. The reaction is exothermic and in some cases cooling is necessary to prevent the temperature from going above 110 C. since this tends to produce discolored and darkened products. The reaction proceeds continuously during addition of the P 0 and solution thereof in the nonionic surface active agent, and is substantially 90% complete or more by the time all of the P 0 has been added.
- the few particles of solid P 0 remaining in the reaction medium may be removed at this point if time is of the essence, but it is preferred in the interests of economy to allow the reaction to proceed for an additional period of time which may range from /2 to 5 hours or more at ambient temperatures up to about 110 C. until all of the P 0 has dissolved indicating complete reaction between the reactants involved. Vigorous agitation during the reaction is highly desirable to facilitate and expedite completion of the reaction.
- the P 0 may be employed in dry, solid form as a granular powder or other finely divided or particulate form, for reaction with the above defined nonionic surface active agents.
- the P 0 may first be dispersed in an inert organic diluent such as benzene, xylene, ether, pentane, or low and high boiling hydrocarbon fractions.
- the reaction mixture may be cooled and discharged. If carried out under rigid anhydrous conditions the product should consist of a mixture of the primary and secondary phosphate esters of the nonionic surface active agent combined, depending upon the proportions of reactants, in some instances with a small proportion of unreacted nonionic surface active agent. Any small amount of water present in the reaction mixture will result protanto in the formation of some phosphoric acid in the product.
- the degree of esterification in the product may be determined by potentiometric titration or by titration with alkali to methyl orange and then to phenolphthalein.
- the products may be supplied in free unneutralized form, or in the form of the partially or completely neutralized salts containing as cations alkali metals, alkaline earth metals, metals, ammonium and organic amines. It is to be understood that such salts are to be regarded as the equivalent of the present products in heir free form.
- suitable cations there may be mentioned sodium, potassium, lithium, calcium, strontium, barium, magnesium, iron, tin, cadmium, aluminum, antimony, chromium, manganese, mercury, nickel, silver, zinc, ammonium and aliphatic, alicyclic, aromatic and heterocyclic organic amines such as the mono-, diand tri-methylamines, ethylamines, propylamines, laurylamines, stearylamines, ethanolamines, propanolamines, butanolamines, hexanolamines, cyclohexylamines, phenylamines, pyridylamines, morpholinylamines, and the like.
- the above products may be modified by the addition to the reaction medium of a small amount of hypophosphorous or phosphorous acid compound.
- Genand prefe ably bout 8 of such compound, based on the weight of the nonionic surface active agent being phosphated is sufiicient to provide the desired improvements with respect to prevention of color degradation of the products and improvement in resistance of the products to color degradation in storage.
- Hypophosphorous acid and its alkali metal salts e.g. sodium and potassium salts are generally preferred although any metal, alkaline earth metal, ammonium or amine salt of hypophosphorous acid or phosphorous acid may be employed, in addition to phosphorous acid per se.
- hypophosphorous acid when employed, it is preferred to use a 30 to 50% aqueous solution thereof although aqueous solutions of this acid and other of the water soluble hypophosphorous and phosphorous acid compounds may be employed in the form of aqueous solutions ranging in concentration from less than 5 up to or more. It should be borne in mind that the reaction should be carried out under substantially anhydrous conditions and accordingly the water introduced in such solutions should be held to a minimum.
- the salts of hypophosphorous acid and phosphorous acid employed herein may be in their hydrated or dehydrated form.
- such salts there may be mentioned aluminum, cadmium, sodium, potassium, lithium, calcium, strontium, barium, magnesium, ammonium, mono-, diand tri-methylamine, -ethylamine, -propylamine, -ethanolamine, and -propanolamine, pyridinyl, and morpholinyl phosphites and hypophosphites.
- Esters of phosphorous acid may also be employed. These esters may be described as mono-, di-, and tri-alkyl, -aryl, and -cycloalkyl phosphites. It will be understood that mixed esters are included. As some specific examples of such esters in which the esterifying group generally contains from about 1 to 20 carbon atoms, there may be mentioned ethyl phosphite, lauryl phosphite, Oxo tridecyl phosphite (the esterifying alcohol having the molecular configuration of an alcohol produced from tetrapropylene or triisobutylene by the 0x0 process), stearyl phosphite, phenyl phosphite, cyclohexyl phosphite, the corresponding diand tri-snbstituted phosphites, ethyl phenyl phosphite, ethyl diphenyl phosphite
- hypophosphorous or phosphorous acid compound is preferably admixed with the non-ionic surface active agent prior to its addition to the nonionic surface active agent. It will accordingly be understood that the hypophosphorous or phosphorous acid compound or mixture thereof may be added at the start of the reaction or continuously or intermittently as the reaction proceeds.
- the nonionic surface active agent is first charged to a reactor equipped with an agitator. If the charge is solid at room temperature, it is heated to melt the same. The additive referred to in the table is then added to and dissolved in the nonionic surface active agent with vigorous agitation. The solid granular P 0 is then charged to the reactor with vigorous agitation over a period ranging from about 5 minutes to about 1 hour and usually about 15 minutes. After the initial exothermic reaction subsides, the reaction mixture is heated to C. and held at this temperature for about 5 hours after which the mixture is cooled and discharged.
- a sample of the reaction mixture is titrated with alkali to methyl orange and then to phenolphthalein as a control on the esterification.
- the VCS color readings are measured in the prescribed manner. A reading of one is the lowest color reading measurable by this method, the highest being 18. Products prepared with the use of the additives referred to in the table sustained no change in color after 3 to 6 months storage.
- a suitable quaternary ammonium compound may be represented by the following structural formula:
- the alkyl moiety may be branched or straight chain, y being hydrogen or an alkyl group as defined above. R" and R need not be the same.
- the quaternary ammonium compounds may be made in ways known in the art, such as for example by dissolving in isopropyl alcohol one mole of dimethyl stearyl amine; then from a separatory funnel add thereto /2 mole of diethyl sulfate keeping temperature below 50 C.; after the last of the diethyl sulfate is added and the exotherm is stopped, reflux for one hour and cool. Evaporate the alcohol.
- Preferred quaternary ammonium compounds include: compounds where R and R" are lower alkyl particularly preferred is wherein R and R" are methyl.
- R may be C saturated or unsaturated, i.e., cocoa, stearic, oleic and the like.
- the quaternized copolymers referred to may be those that are compounds which are first copolymerized and thereafter quaternized or those wherein the monomers are first quaternized and then copolymerized. Procedures known in the art for carrying out the above processes may be employed.

- X is Cl, Br, I, S0 HSO CH SO and M is a monomeric unit resulting from the heteropolymerization employing a mono vinyl monomer different from and co polymerizable with n.
- M may be 5 to 40 where p is 0 to 50; the latter occurring where n, m and p are all employed.
- such quaternary copolymers are prepared by the copolymerization of an N-vinyl lactam, such as N-vinyl pyrrolidone and di-lower alkylaminoalkyl (or hydroxy alkyl) acrylate or methac-,
- N-vinyl lactam such as N-vinyl pyrrolidone and di-lower alkylaminoalkyl (or hydroxy alkyl) acrylate or methac-
- the monomers are copolymerized in accordance with the present invention so that based upon mole percent, the vinyl pyrrolidone units are present in an amount of 40-90 mole percent, the units derived from the di-loweralkylaminoalkyl (or hydroxy alkyl) acrylate or methacrylate constitute from 10 to 60 mole percent, and the units derived from said further copolymerizable vinyl monomer also constitute from 10 to 60 mole percent.
- Suitable heterocyclic N-vinyl lactams have the formula:
