Definitions

  • the present invention relates to treated textile fabric and more particularly, to a method of preparing a liquid and stain resistant, textile fabric that may be printed by transfer printing, and to the fabric so treated.
  • the present invention further pertains to a liquid and stain resistant textile fabric suitable for applications requiring flame barriers without the use of a distinct flame barrier fabric.
  • Stain resistance and water repellency are important in many uses of textile materials.
  • table cloths and seating upholstery often lack stain resistance and are subject to rapid water penetration. These properties necessitate frequent cleaning and/or replacement of such items.
  • Textile fabrics may be made water resistant by various processes. For example, textile fabrics may first be scoured with a soap solution and then treated with a composition which may include zinc and calcium stearates as well as sodium soaps.
  • a composition which may include zinc and calcium stearates as well as sodium soaps.
  • the long chain carboxylic acid hydrophobic compounds provide a limited amount of water repellency. It is also possible to render fabrics liquid resistant by treating the fabric with commercially available silicone, for example poly(dimethylsiloxane).
  • the polymeric coated liquid resistant fabrics cannot be transfer printed because the heat required in the printing process generally causes the polymeric coating to melt or deform.
  • the textile fabric must be printed first by traditional methods, following which it may be treated or polymer coated.
  • the polymer coating generally obscures the design due to its thickness and opacity, even when non-pigmented vinyl, for example, is used.
  • fluorochemicals such as the well known SCOTCHGUARDTM and similar compounds also may confer a limited degree of both water repellency and stain resistance.
  • it has proven necessary to coat fabrics with thick polymeric coatings which completely destroy the hand and feel of the fabric.
  • Examples include vinyl boat covers, where the fabric backing is rendered water resistant by application of considerable quantities of polyvinylchloride latex or the thermoforming of a poly vinyl film onto the fabric.
  • the fabric no longer has the hand and feel of fabric, but is plastic-like.
  • Application of polyurethane films in the melt has also been practiced, with similar results. However, unless aliphatic isocyanate-based polyurethanes are utilized, the coated fabric will rapidly weather.
  • the present invention provides a liquid and stain resistant fabric that is durable enough to withstand the high temperatures required for transfer printing, yet which feels like fabric rather than plastic.
  • the fabric of the present invention is covered with a coating composition comprising a unique composition containing both a copolymer, preferably an aery late copolymer, and at least one fluorochemical.
  • the fabric may be optionally printed by transfer printing, a process well known in the art.
  • the coated fabric can surprisingly withstand the high temperatures of the transfer printing process, thus producing a liquid and stain resistant printed fabric. In many cases, the coated fabric will also exhibit resistance to growth of microorganisms. Best Modes For Carrying Out The Invention
  • the liquid and stain resistant fabric of the present invention retains its natural "hand" or texture and is therefore aesthetically attractive.
  • the fabric of the present invention is also durable, easy to handle and economical to produce. Of especial note is the ability to treat long runs of fabric which is undyed or dyed to a uniform background color, which may be later transfer printed with a suitable design or logo after coating. Transfer printing is uniquely adapted to short runs. The combination of these benefits allows stain resistant, water resistant fabrics of varied patterns to be commercially viable, even in short runs. When fabrics are printed prior to coating, most mills require minimal runs of 2000 yds (1900 m) or more, rendering small runs of printed, then coated fabric, commercially unfeasible. Furthermore, the fabric of the present invention has met various flame retardant codes for the upholstery industry.
  • the fabrics useful in the present invention include, but are not limited to, woven, non- woven and knitted fabrics, and preferably yarn or piece dyed upholstery woven fabrics, of natural fibers, synthetic fibers and mixtures of natural and synthetic fibers.
  • Suitable natural fibers include, but are not limited to, fibers of cotton, linen, ramie, silk, wool and the like.
  • Suitable synthetic fibers include, but are not limited to, fibers of nylon, polyester, acrylic, rayon, acetate and the like.
  • Suitable fabrics for use with the present invention include, but are not limited to, jacquards (i.e., fabrics manufactured from a jacquard loom), brocades, dobbys (i.e., fabrics manufactured from a dobby loom) and canvases.
  • the treated fabric is suitable for replacing the flame barrier and printed fabric in upholstery and other applications, and is further suitable for highly flame retardant commercial and industrial uses, for example, as drapery material.
  • the treating process of the subject invention involves solution coating the fabric with a coating composition which, in its most basic nature, comprises a low solids latex containing a copolymer having a glass transition temperature (T g ) of from 10°C to 35 °C, and a fluorochemical treating agent.
  • T g glass transition temperature
  • the nature of the coating bath and its composition is such that the fabric is thoroughly treated, the topical coating composition covering equally well both sides of the fabric as well as the interstitial spaces within the fabric.
  • the fabric is then oven dried at elevated temperatures, for example, from 250°F to 350°F (121 °C to 177°C).
  • the fabric thusly treated is generally mildew resistant and water repellant.
  • its tensile and tear strengths are markedly improved.
  • the fabric is very difficult to distinguish from untreated fabric by hand, feel, texture, or ease of handling.
  • the latex with the consistency of wallpaper paste or high solids wood glue, is rolled, sprayed, or otherwise applied to the fabric which then passes under a knife blade, doctor blade, or roller which essentially contacts the textile surface, leaving a thin coating of approximately 1.5 oz/yd 2 (50 g/m 2 ) of material.
  • the coated fabric is then oven dried at 250°F to 350°F (121 °C to 277°C). Greater or lesser amounts of this backcoating can be used as desired.
  • the resulting fabric still retains excellent hand and feel, although being somewhat less drapeable than the virgin textile material. Inspection against a light shows very few pinholes, which application of a somewhat thicker coating may further reduce. However, even with the relatively few pinholes, the fabric is virtually completely water resistant, able to support a considerable column of water without leakage. If further water resistance is required, this second treatment may be repeated.
  • the processes of treating textile fabric and the properties of the treated fabric in accordance with the present invention may best be understood in relation to the following detailed description.
  • the first step in the process of treating fabric in accordance with the present invention involves the application of a penetrating topical coating to the fabric followed by oven drying.
  • the topical coating formulation hereinafter referred to as the primary coating or coating composition, is an aqueous bath containing from 3 weight percent to about 25 weight percent solids, preferably from 4 weight percent to 20 weight percent solids, of which approximately 20 weight percent to 50 weight percent represent latex copolymer solids.
  • This primary, topical treatment bath contains minimally the following components: a copolymer latex; and a fluorochemical textile treating composition.
  • the primary bath may further include a cross linking agent, an anti-microbial agent a fire retardant and/or smoke suppressant, and other additives and auxiliaries such as dispersants, thickeners, dyes, pigments, ultraviolet light stabilizers, and the like.
  • the copolymer latex is present in an amount sufficient to supply preferably 3 to about 12 weight percent solids to the formulation, more preferably 3 to about 10 weight percent, and most preferably 4 to about 7 weight percent.
  • the copolymer particles constituting the latex solids should have a glass transition temperature less than 50°C, preferably in the range of 10 to 35°C, most preferably about 20 °C. Copolymers having glass transition temperatures appreciably below 10° to 3 °C, most preferably about 20°C. Copolymers having glass transition temperatures appreciably below 10° C may not present optimal stain resistance.
  • the surfactant content of the latex is as low as possible to provide for good water repellency and water resistance.
  • the nature of the monomers from which the polymer particles of the copolymer latex may be formed may be adjusted by one skilled in the art to provide the properties desired of the coated fabric.
  • the latex particles are acrylate copolymers, i.e. copolymers formed from lower alkyl acrylates such as methylacrylate, ethylacrylate, butylacrylate, methylmethacrylate, 2- ethylhexylacrylate, and the like, as well as additional copolymerizable monomers such as vinyl acetate, acrylonitrile, styrene, acrylic acid, acrylamide, -methylacrylamide, and urethane acrylates.
  • This list of commoners is exemplary and not limiting.
  • crosslinkable groups such as acrylamide and N- methylacrylamide along the polymer backbone
  • crosslinkable groups such as acrylamide and N- methylacrylamide along the polymer backbone
  • Terpolymers of styrene, methylacrylate, and ethylacrylate are very suitable. Most preferred is WRL1084, a styrene, methylacrylate, ethylacrylate copolymer containing N-methylacrylamide in the polymer backbone available from B.F. Goodrich.
  • the copolymer lattices are available in varying solids contents, for example, from 30 to 60 weight percent, which are then added to formulating water to provide the desired solids content in the first coating composition.
  • the antimicrobial agent if present, comprises preferably about 0.25% to about 4% by weight of the aqueous coating composition more preferably 0.40 to about 2 weight percent, and most preferably 0.40 to 1 weight percent.
  • antimicrobial agent is meant any substance or combination of substances that kills or prevents the growth of a microorganism, and includes antibiotics, antifungal, antiviral and antialgal agents.
  • the preferred antimicrobial agent is ULTRA FRESHTM, available from Thomas Research, and INTERSEPTTM, available from Interface Research Corporation, may also be employed. Other antimicrobials, particularly fungicides, may be used.
  • Examples are various tin compounds, particularly trialkyltin compounds such as tributyl tin oxide and tributyl tin acetate, copper compounds such as copper 8-quinolinolate, metal complexes of dehydroabietyl amine and 8-hydroxyquinolinium 2-ethylhexoate, copper naphthenate, copper oleate, and organosilicon quaternary ammonium compounds.
  • antimicrobial agents are not necessary to prevent significant microbial growth, as the combination of acrylate copolymer, fluorochemical, and crosslinker, when present, aids in this respect.
  • the fluorochemical textile treating agent comprises about 6 % to about 12% by weight of the coating composition, preferably 10% .
  • the fluorochemicals provide water and stain resistance and may comprise unbranded generic fluoropolymers.
  • Commercially available fluorochemical compositions such as SCOTCHGUARDTM FC 255, SCOTCHGUARDTM FC 214-230, available from 3M, and TEFLON ® RN, TEFLON ® 8070, and TEFLONTM 8787, available from Dupont, are preferred.
  • TEFLONTM 8070 is the most preferred fluorochemical. It is noteworthy that the amount of fluorochemical treating agent used is considerably higher than amounts traditionally used for treating upholstery fabric to render it stain resistant.
  • the fluorochemical may be a fluorine-containing acrylate, acrylate copolymer, or other polymer or copolymer.
  • Crosslinking agents suitable for use in the present invention include both chemical agents which promote crosslinking of crosslinkable groups along the latex copolymer chains as well as crosslinkable resins which may crosslink with the copolymer or which are themselves crosslinkable.
  • a preferred crosslinking agent which facilitates copolymer crosslinking is zinc ammonium carbonate.
  • Preferred self-crosslinking resins are the various melamine/formaldehyde and phenol/formaldehyde resins and their variants, particularly CYREZ ® 933, a product of the American Cyanamid Company.
  • Other phenol, melamine, urea, and dicyandiamide based formaldehyde resins are available commercially, for example, from the Borden Chemical Company.
  • melamine/formaldehyde resin in the amount of 0.1 to about 1.0 weight percent, preferably about 0.25 weight percent based on the weight of the aqueous treating composition is used.
  • Other crosslinkable resins such as oligomeric unsaturated polyesters, mixtures of polyacrylic acid and polyols, e.g. polyvinylalcohol, and epoxy resins may also be used, together with any necessary catalysts to ensure crosslinking during the oven drying cycle.
  • the fabrics produced by the subject process are, in general, flame retardant. However, it would not depart from the spirit of the invention to add additional flame retardants and/or smoke suppressants.
  • Suitable flame retardants are known to those skilled in the art of fabric finishing, and include, for example, cyclic phosphorate esters such as Antiblaze 19T available from Mobil Chemical Co.
  • the order of mixing the ingredients of the primary bath is not very critical.
  • the copolymer latex is first mixed with make-up water and stirred at ambient temperature until uniformly dispersed, following which the antimicrobial agent, if any, and fluorochemical treating agent and other ingredients are added. The mixture is stirred until a uniform dispersion is obtained.
  • the fabric to be coated may be drawn through the treating bath by any convenient method, or the treatment solution may be sprayed or rolled onto the fabric.
  • the fabric previously scoured to remove textile yarn finishes, soaps, etc. , is drawn through the bath, as the topical treatment of the first treating step should uniformly coat both surfaces of the textile as well as its interior.
  • the fabric after being drawn through the bath, may be passed through nips or nip rollers to facilitate more thorough penetration of the treating composition into the fabric and/or to adjust the amount of treatment composition by the fabric.
  • the pickup is adjusted to provide from 30 to 200 weight percent pickup relative to the weight of the untreated fabric, more preferably from 60 to 150 weight percent, and most preferably from 80 to 120 weight percent.
  • a 100 weight percent addition of treatment solution is considered optimal with normal primary bath solids content.
  • the treated fabric is then passed through an oven maintained at an elevated temperature, preferably from 250°F to 350°F (121 °C to 277°C) for a period sufficient to dry the applied coating, and, if the first treatment step is not to be followed by additional treatment, to perform any necessary crosslinking of the components of the treatment composition. Generally, a period of from 1 to 8 minutes, preferably about 2 minutes at 325 °F (163°C) is sufficient.
  • the treating process of the subject invention is advantageously applied to flame barrier fabrics prepared from corespun yarns, preferably with a fiberglass core, as disclosed in U.S. Patent Nos. 4,921,756, 4,996,099, and 5,091,243.
  • the yarns used in these fabrics comprise an interior core of fiberglass or other non- flammable fiber covered by a shell of polymeric synthetic fibers.
  • the synthetic fibers are staple fibers, and are overwrapped in a spiral fashion by continuous fibers to maintain yarn integrity.
  • Other flame barrier fabrics may be utilized as well.
  • the polymeric synthetic fiber which surrounds the non-flammable core of the corespun yarn may be one of a number of synthetic polymer fibers, including, but not limited to, acrylic, modacrylic, polyester, nylon, and the like.
  • the synthetic polymer fibers should be able to withstand the heat of the transfer printing process.
  • the use of the treated barrier fabric provides a covering which not only possesses the necessary flame barrier properties, but moreover is liquid resistant and stain resistant.
  • the treated barrier fabrics may be transfer printed, thus allowing for aesthetic exterior uses, not only in furniture upholstery, but in other applications requiring a high level of flame resistance such as commercial and institutional draperies and wall coverings.
  • exterior upholstery use eliminates the necessity of a separate barrier fabric. Such uses amount not only to considerable savings in manufacture and thus ultimate consumer cost, but moreover, can effect substantial weight savings, important in such application as commercial aircraft seating.
  • the treated fabric of the subject invention has a number of advantageous and unique characteristics. It is highly, although not totally, water resistant, as well as stain resistant and sufficiently non-flammable to meet various flammability requirements such as California 117, Section E. While highly water resistant, the fabric allows ready passage of water vapor, and is thus eminently suited for items such as boat covers, traditionally made of vinyl-coated fabrics.
  • the vinyl-coated fabrics are substantially water vapor impermeable, and contribute to mildew formulation in boats using such covers.
  • the treated fabric has substantially the same hand, feel, texture, and drape of uncoated fabric, and thus can be manipulated by traditional manufacturing techniques as well as being aesthetically pleasing.
  • the fabric is also considerably more resistant to tear and opening at needle holes, as well as having higher tensile strength. Importantly, the treated fabric may be transfer printed.
  • the secondary treatment compositions utilized for the second and subsequent treatments are different from those of the primary treatment, although the latter treatment may be repeated as well.
  • the second and subsequent treatments are designed to increase stain resistance and also to render the fabric virtually totally water resistant. Like the fabrics which receive only one or more primary treatments, the fabrics obtained after treatment with the secondary treatment composition are able to be transfer printed without difficulty.
  • the second treatment composition comprises a copolymer latex and a fluorochemical textile treatment agent.
  • the copolymer of the copolymer latex of the secondary treatment composition has a glass transition temperature of 0°C or lower, preferably -10°C or lower, and preferably within the range of -40 °C to -10°C, and is preferably a styrene/acrylate copolymer.
  • the amount of copolymer latex solids is also considerably higher, for example, 90-95% of a 50% solids latex.
  • the treatment composition should contain from 30 to 60 weight percent copolymer solids, preferably 35 to 55 weight percent, and most preferably about 45 to 52 weight percent.
  • the second treatment composition may also comprise one or more antimicrobial agent(s).
  • Thickeners are generally necessary to adjust the rheological properties of the secondary treatment composition.
  • Such thickeners are well known, and include water soluble, generally high molecular weight natural and synthetic materials, particularly the latter.
  • natural thickeners include the various water soluble gums such as gum acacia, gum tragacanth, guar gum, and the like. More preferred are the chemically modified celluloses and starches, such as methy cellulose, hydroxymethylcellulose, propylcellulose, and the like.
  • high molecular weight synthetic polymers such as polyacrylic acid; copolymers of acrylic acid with minor amounts of copolymerizable monomers such as methyl acrylate, methacrylic acid, acrylonitrile, vinylacetate, and the like, as well as the salts of these compounds with alkali metal ions or ammonium ions; polyvinylalcohol and partially hydrolyzed poly vinylacetate; poly acrylamide; polyoxyethylene glycol; and the so-called associative thickeners such as the long chain alkylene oxide capped polyoxyethylene glycols and polyols or their copolymer polyoxyethylene/polyoxypropylene analogues.
  • the length of the carbon chain of the long chain alkylene oxide in associative thickeners has a great effect on the thickening efficiency, with alkylene residues of 8-30 carbon atoms, preferably 14-24 carbon atoms having great thickening efficiency.
  • the thickener may be used in amounts up to 4 weight percent, preferably about 2 weight percent or less. In contrast to the copolymer latex, in which the solids are dispersed, the thickener solids are water soluble in the amounts used.
  • the remaining ingredients are similar to those of the first treatment composition, and may include, based on 200 lbs (91 Kg) of 50% solids treatment composition, from 2 to 12 lbs (0.91 to 5.4 Kg) fluorochemical textile treating agent, preferably 4 to 10 lbs (1.8 to 4.5 Kg), and most preferably, 6 to 8 lbs (2.7 to 3.6 Kg); optionally 0.25 to 3 lb (0.11 to 1.4 Kg) of one or more microbicides, more preferably 0.5 to 2 lbs (0.23 to 0.91 Kg), and most preferably about 0.5 lb (0.23 Kg) each of ULTRAFRESHTM DM-50 and ULTRAFRESHTM UF-40 biocides available from Thompson Research Corporation.
  • the preferred compositions further contain 2 weight percent zinc ammonium carbonate; 20 lbs (9.1 Kg) of an aqueous 50% solids calcium stearate dispersion; 2 lbs (0.91 Kg) zinc borate; 0 to 3 lbs (0 to 1.4 Kg) melamine/formaldehyde resin, preferably CYREZ 933; and 2 weight percent of sodium poly aery late thickener solids, supplied as a 14 to 20 weight percent solids solution.
  • 2 weight percent zinc ammonium carbonate 20 lbs (9.1 Kg) of an aqueous 50% solids calcium stearate dispersion
  • 2 lbs (0.91 Kg) zinc borate 0 to 3 lbs (0 to 1.4 Kg) melamine/formaldehyde resin, preferably CYREZ 933
  • 2 weight percent of sodium poly aery late thickener solids supplied as a 14 to 20 weight percent solids solution.
  • Fire retardants which are dispersible may be added to the secondary treatment composition in the place of or in addition to those previously described.
  • Caliban P-44 containing decabromodiphenyloxide and antimony oxide available from White Chemical Company.
  • a suitable smoke suppressant is zinc borate, which may be used in the amount of 2 weight percent based on solids.
  • the resulting composition is considerably more viscous than the first treatment composition, and has a consistency similar to that of PVA wood glue or wallpaper paste.
  • the composition may further contain 3 to 7 weight percent polydimethylsiloxane silicone fluid. This fluid counteracts the tackiness which may develop in the coating during the elevated temperatures associated with transfer printing which might otherwise result in the coating sticking to the print blanket which surrounds the heated transfer printing roll.
  • the second and subsequent treatments are applied to one side of the fabric only, the side to be exposed to the environment and to be optionally transfer printed.
  • the amount of the secondary treatment applied may vary.
  • a doctor blade or knife edge is adjusted to touch or nearly touch the fabric surface as the fabric, coated with the composition, passes by.
  • the coating may be as much as 1 mm thick above the fabric, it is preferred that the wet surface of the coating be at substantially the height of the uppermost yarns of the fabric. When subsequently dried, the thickness of the coating will, of course, be considerably reduced.
  • the primary treatment precede the secondary or subsequent treatment(s) .
  • the primary treatment interferes with the penetration of the secondary treatment into the fabric, and thus limits the amount of secondary treatment composition which the fabric can obtain with a given knife blade setting.
  • the inability of the secondary treatment composition to substantially penetrate into the fabric assists in maintaining the hand and feel of the fabric, which otherwise would be stiff and boardy.
  • the fabric again is oven dried, at temperatures from 250°F to 350°F (121 °C to 277°C), preferably 300 to 350°F
  • the amount of the copolymer composition, fluorochemicals and other additives, such as antimicrobial agents may be varied depending on the desired result of the coating composition.
  • fabric of tighter weave may require only a primary treatment or a primary treatment and one secondary treatment whereas an open weave fabric may require primary treatment and two or more secondary treatments.
  • the combination of the various components of the composition of the present invention may be varied to achieve the desired result.
  • the solids content of the primary treatment composition, secondary composition, or both may be increased to reduce the overall number of treatments required.
  • the fabric may be caused to be printed by transfer printing.
  • Transfer printing is generally known in the art.
  • color designs mounted on paper carriers are transferred to the coated fabric.
  • the color designs may be transferred from the paper carriers to the coated fabric by pressure-heat contact methods or by heat-vaporization (sublimation) methods.
  • pressure-heat contact methods or by heat-vaporization (sublimation) methods.
  • color-prints on a paper carrier are made to come in continuous contact with the treated fabric, and while in contact, pressure is applied between a blanket and a roller. The pressure is about 50 lbs/in 2 (34 N/cm 2 ) to about 60 lbs/in 2 (41 N/cm 2 ), with 60 lbs/in 2 (41 N/cm 2 ) preferred.
  • Heat is also applied at about 380°F to about 430°F (193°C to 221 °C), preferably at 420°F (216°C).
  • the dwell time, or time where heat and/or pressure are applied, is a time sufficient for the prints to be transferred to the fabric, preferably about 15 sec to about 30 sec.
  • the heat and pressure permit the transfer of the color design from the paper carrier to the fabric. Transfer of the prints from the paper carrier can also be effected by the use of heat-vaporization methods, known to those skilled in the art.
  • the coated fabric of the present invention may have color prints printed thereon in any number of ways, and there is no limitation on the number of colors, the variations and graduation of color, and number of different configurations of prints that can be applied. Moreover, there are any number of ways such prints can be transferred to the coated fabrics and the above are merely representative methods.
  • the fabric of the present invention is durable, easy to handle and economical to produce. Because the fabric retains its "hand" or texture, the fabric is easy to sew and seams are less noticeable, and more durable. For example, when vinyl is sewed, the needle holes tend to open when the vinyl is stretched. With the fabric of the present invention, needle holes do not tend to open and thus the seams are stronger and less noticeable.
  • the fabric of the present invention also has flame retardant characteristics, as described in greater detail below. Moreover, while the fabric provides a moisture barrier, it is believed that vapors are allowed to pass through the fabric. Human skin which may come in contact with the fabric, for example in upholstery applications, is therefore less likely to perspire.
  • the treated fabric was passed through nip rolls whose pressure was adjusted to provide for 100% primary treatment composition pickup.
  • the fabric was then dried for approximately 2 minutes by passage through a drying oven maintained at 325 °F (163 °C).
  • the treated fabric exhibited a c.a. 9% weight gain after drying.
  • the resulting treated fabric displayed virtually no change in color, was able to support a considerable column of water, indicating good water resistance, and was stain resistant.
  • the fabric was water vapor permeable, and had excellent hand, feel, and texture.
  • the tear strength and tensile strength was considerably improved relative to the untreated fabric. Examination of the fabric against a strong light showed the presence of numerous pinholes. Nevertheless, the water resistance was such as to make the fabric eminently well suited for boat covers and other outdoor applications, particularly those where water vapor transmission is desirable.
