Definitions
- Antistatic textile products particularly those having a pile type structure on one side of a woven layer, such as carpets, are produced by applying to one side only (e.g., the woven side rather than the pile side in the case of carpets), an antistatic composition consisting essentially of a mixture of (a) an organic textile antistatic agent,
- a humectant which may be either an ionic humectant
- glycerin such as glycerin, or a nonionic 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 fibrous textile layer and the polymeric backing layer.
- electrolyte such as calcium chloride or sodium chloride
- This invention is concerned with an antistatic carpet structure. More specifically this invention relates to an antistatic carpet structure which has a fibrous layer, an antistatic, conductive coating, and a polymeric backing.
- Conventional carpet structures 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 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 fibrous 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 for the individual. The above described problem can be eliminated if the charges of static electricity can be dispersed throughout the carpet structure, and subsequently dissipated into the air.
- the prior art discloses a plurality of antistatic compositions and one antistatic carpet structure.
- this antistatic carpet structure of US. Pat. 2,302,003, Cadwell et al. accumulated charges are dispersed via a plurality of conducting fibers which are positioned throughout the fibrous layer.
- the carpet structure of this invention disperses, quickly and thoroughly, charges of static electricity without the need of specific conducting fibers.
- the carpet structure of this invention bleeds olf charges of static electricity via a critical conducting layer.
- the con- 3,510,386 Patented May 5, 1970 tinuous conducting layer of the subject carpet structure must be such that it is capable of bleeding and dispersing charges of static electricity.
- said antistatic layer must not be of such a thickness that it interferes with the aesthetic qualities of the carpet.
- the antistatic carpet structure of this invention incorporates a polymeric backing.
- the vast majority of the prior art antistatic compositions are not compatible with polymeric backings. Because of this incompatibility carpets which are treated with these prior art antistatic compositions could not utilize most polymeric backings, and par ticularly the commonly used natural latex backing.
- the antistatic coating of this composition as utilized in the carpet structure of this invention is compatible with natural latex backings and most other polymeric coating compounds. Therefore, the antistatic carpet structure of this invention can utilize a latex backing.
- the subject antistatic carpet structure is illustrated in the single figure of the accompanying drawing.
- the carpet structure 2 has a conventional 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 aflixed 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 5 to which the fiber forming pile is afiixed or through which it is tufted, etc. is coated with an antistatic coating 6 which provides a uniform continuous layer and coats and contacts the backing and the ends of the fibers forming the pile in contact therewith.
- the amount of material applied as such antistatic coating should be suflicient to substantially penetrate the backing and that part of the fibers in contact therewith, but preferably should not be applied in such a manner or such an amount as to extend to the face of the fibrous (pile) layer 4, less it detract from the aesthetic properties of the fibrous layer. Normally from .01 to 12 ounces per square yard and preferably from 0.5 to 3.0 ounces per square yard of the antistatic coating is applied.
- the antistatic coating composition employed for the antistatic coating layer 6 consists essentially of a mixture of a textile antistatic agent and a humectant in proportions of about 4 to 8 parts by weight of antistatic agent and 10 to 50 parts by weight of humecant. There is also preferably included from 0.1 to about 1 part by weight of a nonionic or cationic type wetting agent to assist in the penetration of the antistatic composition into the textile substrate. It is desirable to add the wetting agent in controlled amount (determined by preliminary test) to thereby control the degree of penetration of the composition into the textile substrate so that the antistatic coating composition penetrates the backing of the carpet and wets the base of the pile fabric, but does not penetrate to the outer tips of the pile.
- the coating composition 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.
- 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 compounded 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.
- the polymeric coating 8 serves the function of holding the antistatic coating layer 6 in place. 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 suchcharges to the ground, the polymeric coating 8 may have incorporated in it a material such as carbon black or any agent which will lower the dielectric properties of the polymeric layer.
- compositions for the antistatic coating layer 6 of the carpet structure of the present invention are disclosed in the copending application of Andrew Kelly and Robert C. Britt entitled Antistatic Composition and Process, Ser. No. 559,859, filed June 23, 1966 concurrently with this application.
- the antistatic coatings containing calcium chloride are incompatible with certain known latex coatings which have been used as carpet backings in that they cause premature coagulation or gelling of the late): 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 copending application are particularly preferred, it will be understood that we may employ any antistatic layer based on any known antistatic "material suitable for textiles which will disperse charges of static electricity.
- antistatic agents are normally nitrogen containing or carboxylic'containingorganic antistatic agents and as examples thereof may be mentioned the following compounds:
- Amine oxides or quaternary ammonium salts of vinyl pyrrolidone-dimethylamino-ethylmethacrylate copolymers are examples of vinyl pyrrolidone-dimethylamino-ethylmethacrylate copolymers.
- Vinyl pyrrolidone-acrylamine copolymers such as a copolymer of 75% vinyl pyrrolidone and 25% acrylamide.
- Catanac SNstearylamidopropyl dimethyl-fi-hydroxyethyl ammonium nitrate Catanac SNstearylamidopropyl dimethyl-fi-hydroxyethyl ammonium nitrate.
- Ethoquad C/ 12 polyoxyethylated monium salt.
- Phosphonamide sulfonate of an alcohol ethoxylate i.e. a product of the formula quaternary amwherein R represents the hydrocarbon residue of an alkanol (such as'Alfol 1412) and n represents an integer of 8 to 30.
- Triesters of phosphoric acid and ethoxylated aliphatic alcohol such as the phosphate triester of lauryl alcohol condensed with 4 moles of ethylene oxide or of dodecyl alcohol condensed with about 2 moles of ethylene oxide.
- Methyl diethanolamine ethoxylate Methyl diethanolamine ethoxylate.
- Oleic-monoisopropanol amide Oleic-monoisopropanol amide.
- R represents an aliphatic hydrocarbon radical of from about 8 to about 22 carbon atoms, each R represents hydrogen or methyl and n represents an average integer of at least 1, preferably 1 to about 30, although higher alkoxylated derivatives, i.e. the products obtained by condensing 1 molar proportion of a primary aliphatic (saturated or unsaturated) amine with up to 50 molar proportions of an alkylene oxide, usually ethylene oxide,
- alkoxylated amines are well known in the art and are'prepared by condensing the primary saturated or unsaturated aliphatic amine of from 8 to 22 carbon atoms, with an alkylene oxide, usually ethylene oxide, although propyene oxide and butylene oxide may be employed if desired, until glycol groups of desired chain length are obtained.
- alkylene oxide usually ethylene oxide, although propyene oxide and butylene oxide may be employed if desired, until glycol groups of desired chain length are obtained.
- Such products have been disclosed, for example in US. Pats. 1,970,578, 2,174,762, 2,510,284 and 2,593,466.
- humectant in the composition of the present invention there may be used various deliquescent salts of metals of the Groups I and II, Periodic Table, particularly of the alkali metal and alkaline earth metals.
- Specific deliquescent salts which we prefer to employ as humectant include the alkali metal salts of lower aliphatic carboxylic acids, such as sodium formate, potassium formate, lithium formate, cesium formate, sodium and potassium acetate, potassium butyrate and mineral acid salts like calcium chloride.
- organic humectants as glycerol, urea, ethylene glycol, sorbitol, ethoxylated sorbitol, lauric acid esters and mixtures of the same.
- deliquescent salt such as sodium and potassium formate which have a relatively low dissociation constant, it is preferable to 6 with 20 moles of ethylene oxide per mole of amine.
- the wetting agent was tridecyl alcohol which had been ethoxylated with 6 moles of ethylene oxide per mole of alcohol. The amounts of materials employed in each example are given in the appropriate column of Table I.
- the antistatic coating was applied to the back of a tufted carpet having a primary loosely woven jute backing, and the type of fibers employed in the tufted pile are given in Table I as well as the amount of antistatic composition applied to the back of the carpet. After application of the antistatic coating the carpet was dried to remove excess moisture. A latex coating was then applied over the antistatic coating in such a manner that it did not encapsulate the antis-tatic coating.
- the testing procedure used in these examples was the Walking Foot Scuff Test. This testing procedure is as follows: A carpet sample 9 feet longand 2 to 3 feet wide is spread on the floor. At one end of the carpet an electrostatic volt meter is positioned on a table. Beginning at the volt meter end of the carpet, the experimenter, wearing shoes having leather soles and heels, walks, shuffling his feet all the While to the opposite end, turns while still on the carpet, and returns to the volt meter end of the carpet where he immediately makes a hand contact with the probe. The electrical charge which is accumulated in the experimenter is transmitted to and registered on the volt meter. In all examples the testing was conducted at 77 F.i2 F. and at a constant relative humidity of to TABLE I Hulnectant Coating,
- humectant and electrolyte may be either a single compound or a mixture of compounds.

- EXAMPLES 1541 In these examples the samples treated Were nylon and Wool tufted carpet structures. In all cases the antistatic coating was applied to the base of the carpet fibers and primary jute and dried. A latex coating was then applied over the antistatic coating in such a fashion that it did not encapsulate the antistatic coating.
- humectant was formed in situ by the reaction of a basic component with an acidic component.
- the amine and wetting agent were the same as described in regard to Examples 1 to 12.
- the testing procedure used in these examples was the Stationary Foot Scuff Test. This procedure is as follows:
- the carpet to be tested is spread on the floor (18" x 18 minimum) and the person testing, wearing shoes having leather soles and heels stands on the carpetwith one foot stationary. While holding a volt meter in one hand, the experimenter rubs his other foot briskly on the carpet pile, a maximum of 15 strokes or until the meter reaches equilibrium, Any charge generated is transmitted through the person and registered on the volt meter. This testing was conducted at 77 F.:2 F., and at a constant relative humidity'of 35 to 40%.
- composition of the antistatic coating as well as the test results and other pertinent information for these examples are given in Table II.
- EXAMPLES 32-46 In these examples the samples treated were nylon and wool tufted carpet structures.

- the procedure for these examples was as follows:
- the samples were cut and coated with the antistatic coating.
- the coating weight was based on the weight of the fabric in question.
- a polymeric backing was then applied to the fabric and dried at a temperature of from about 200 to 325 F. for a period of time of from about 10 to 30 minutes.
- the dried fabric was then conditioned for at least six hours at a temperature of i5 F. and 35 to 40% relative humidity.
- the coated material was then tested on an Atlab Tester, as developed by the Atlas Chemical Co., Wilmington, Del.
