Definitions

• the present invention relates generally to tacky cloths suitable for the removal of dirt, dust and other particulate contaminants (hereinafter simply referred to as dirt) from various surfaces.
• tacky cloths are commonly referred to as tack-rags.
• Tack-rags are normally produced by dipping a cloth material in a solution or dispersion of a tacky resin, then allowing the liquid medium to evaporate.
• the resins generally utilized are water-insoluble in order to facilitate cleaning and further use. Eventually, however, the tack-rags wear out and must be thrown away.
• a tack-rag which comprises a cloth material impregnated with a tacky resin, characterized in that the tacky resin is a non-drying tacky resin comprising an oligomer or polymer which possesses
• the tack-rags in accordance with the present invention have the advantage that, subsequent to use, they can be water-washed to substantially completely separate the resin and collected dirt from the cloth material.
• the resin is water-soluble because it possesses a water-solubilizing amount of (a) one or more non-ionic water-solubilizing groups, (b1) one or more ionic groups which have been neutralized with a non-volatile neutralizing agent in order to render those ionic groups water-solubilizing or (c) combinations thereof, it is not necessary to utilize any additives such as tensides in the wash water to effect substantially complete separation of the resin from the cloth material.
• the only needed additive to the wash water is a non-volatile neutralizing agent which becomes associated with the ionic groups of the resin in order to render the ionic groups water-solubilizing and the resin water-soluble. Again, therefore, no tensides and the like are needed to effect substantially complete separation of the resin from the cloth material.
• the so-washed cloth material if in sufficiently good shape, can be reimpregnated with the tacky resin and used again as a tack-rag, or can merely be used for normal cleaning purposes. If disposal of the cloth material is required, the cloth material being substantially free of resin can simply be disposed of as normal waste.
• the resin dissolved in the wash water can readily be recycled by removal of the dirt, e.g., by filtration, then concentration of the resin solution.
• the concentrated resin solution can then be reused as such or combined with fresh resin solution for (re)impregnating the cloth material.
• the tack-rags in accordance with the present invention comprise a cloth material impregnated with a tacky resin, characterized in that the tacky resin is a non-drying tacky resin comprising an oligomer or polymer which possesses
• cloth materials Any one of a number of natural and/or artificial cloth materials may be considered suitable for use with the present invention.
• These cloth materials are generally known to those skilled in the art and include, for example, woven, non-woven and knitted cloths of cotton, polyester, wool, acrylic, nylon, rayon, cellulose (papers) and viscose fibers, as well as natural and synthetic leather.
• woven, non-woven and knitted cloths of cotton, polyester, wool, acrylic, nylon, rayon, cellulose (papers) and viscose fibers as well as natural and synthetic leather.
• cotton, staple rayon and mixtures thereof are especially preferred.
• tacky resins may be mentioned those that are non-drying and either water-soluble or capable of being rendered water-soluble by neutralizing ionic groups with a non-volatile neutralizing agent.
• non-drying it is meant that the resin dries by physical evaporation of the solvents to form a film in which the resin molecules retain their original chemical form, i.e., essentially no chemical reaction occurs such as crosslinking with a curing agent or via autoxidation at temperatures of up to about 150°C.
• the resin therefore, should retain its tacky character at temperatures of normal use.
• Suitable non-ionic water-solubilizing groups are well-known to those skilled in the art and include, for example, polyoxyalkylene groups such as polyoxyethylene and polyoxypropylene groups, as well as other hydrophilic groups based upon polyvinyl alcohols, polymers of hydroxy (meth)acrylates and other hydroxyl groups-containing oligomers and polymers. Preferred among these for use with the present invention are the polyoxyalkylene groups and, especially, polyoxyethylene groups.
• Suitable ionic groups which require neutralization in order to be water-solubilizing are once again well-known to those skilled in the art and include, for example, carboxyl (anionic) and amino (cationic) groups, which are preferred.
• these ionic groups must be capable of being rendered water-solubilizing by neutralization with a non-volatile neutralizing agent.
• non-volatile is it meant that the neutralizing agent, once associated with the ionic group, does not readily dissociate from it and evaporate on drying. In other words, the salt formed on neutralization remains part of the resin upon drying, which is considered important in order to provide solubility of the resin in the wash water without the necessity for using additional tensides.
• Suitable non-volatile neutralizing agents for anionic groups include strong bases such as alkali metal hydroxides, as well as higher molecular weight polyoxyalkylene amines such as those commercially available under the trade designation "Jeffamine” from Texaco Chemical Company.
• Preferred for use with the present invention include the alkali metal hydroxides such as LiOH, NaOH and KOH.
• Suitable non-volatile neutralizing agents for cationic groups include inorganic strong acids such as phosphoric acid and sulfuric acid, as well as organic acids such as fatty acids and citric acid. Preferred for use with the present invention is phosphoric acid.
• the resin should have an acid number or amine number of at least 20, preferably in the range of 20 to 275, and especially in the range of 40 to 90, in order for the resin to be rendered water-soluble upon neutralization of the ionic groups.
• the resins may also comprise combinations of these various water-solubilizing groups. If such combinations are utilized, one skilled in the art can readily determine the required amount of each of such groups in order to render the resin water-soluble.
• resins suitable for use with the present invention may be mentioned the following:
• the cloth material may be impregnated with the tacky resin in any normal manner such as, for example, by dipping the cloth material into a solution or dispersion of the tacky resin or spraying such solution onto the cloth material, then allowing the solvent to evaporate. Evaporation can be accelerated through drying at slightly elevated temperatures and/or via air convection.
• suitable solvents may be mentioned any one of a number of organic solvents such as, for example, butyl acetate, xylene, white spirits and mixtures of water and a water-miscible solvent such as butyl glycol, as well as water in the case that the tacky resins are water-soluble.
• organic solvents such as, for example, butyl acetate, xylene, white spirits and mixtures of water and a water-miscible solvent such as butyl glycol, as well as water in the case that the tacky resins are water-soluble.
• solutions or dispersions of the resins are utilized for impregnating the cloth material with the tacky resins.
• a dipping procedure is generally used with a continuous roll of material being passed through a bath of resin solution.
• the viscosity of the solution is adjusted such that, after passing through rollers to remove excess resin then drying at ca. 100°C for 5-10 minutes, the weight of the so-impreganted cloth material amounts to 180-220% of the original cloth material weight (80-120% by weight added resin based upon the orignal weight of the cloth material).
• This procedure is controlled by weighing samples of the cloth material before and after impregnation.
• the so-impregnated cloth material is then suitable for use as a dirt collector in various fields, but is especially suited for use as a tack-rag in the automotive field.
• the tack-rags impregnated with a water-soluble non-drying tacky resin as described above can be readily cleaned by washing in water without the addition of tensides or the like which might create disposal problems with respect to the wash water. By so-washing the tack-rags, the resin and dirt can readily be substantially completely separated from the cloth material.
• the tack-rags impregnated with a non-water-soluble non-drying tacky resin as described above can be washed in the same manner as those impregnated with a water-soluble resin with the exception that the wash water must contain a sufficient amount of a non-volatile neutralizing agent in order to neutralize a water-solubilizing amount of ionic groups present in such resin. Again by so-washing, the resin and dirt can readily be substantially completely separated from the cloth material.
• the so-washed cloth material if in sufficiently good shape, can be reimpregnated with the tacky resin and used again as a tack-rag, or can merely be used for normal cleaning purposes. If disposal of the cloth material is required, the cloth material being substantially free of resin and dirt can simply be disposed of as normal waste.
• the resin dissolved in the wash water can readily be recycled by removal of the dirt, e.g, by filtration, then concentration of the resin solution.
• the concentrated resin solution can then be reused as such or combined with fresh resin solution for (re)impregnating the cloth material.
• a non-drying alkyd resin (from unsaturated branched fatty acids, dicarboxylic acids and polyols), having a molecular weight of 1480 and an acid value of 68, was thinned with a 70/30 butyl acetate/butyl glycol solution to a solid content of 60 wt% and subsequently neutralized to 70% with a 40 wt% solution of sodium hydroxide in water.
• An epoxide-amine adduct from one mole of an epoxide resin (commercially available under the trade designation Epikote 828 from Shell) and two moles diethanolamine was thinned with butyl acetate to 60 wt%, then further thinned with butyl acetate to a viscosity of 50 seconds (DIN 4mm cup, 23°C).
• An epoxide-amine adduct from one mole of an epoxide resin (commercially available under the trade designation Epikote 1001 from Shell) and two moles diethanolamine was thinned with butyl acetate to 60 wt% then subsequently neutralized to 100% with phosphoric acid.
• Cotton/rayon mixed cloth material was impregnated by dipping in the resin solution until, after drying at 100°C for 10 minutes, the cloth weighed about 200% of its original weight.
• Tack-rags so-produced from each of Resin Solutions 1-5 had a tacky feel and exhibited excellent tack-rag properties, removing dirt from painted panels completely without smearing or leaving any residue on the painted surface.
