Definitions

  • the present invention relates to improved methods for adhering secondary backing to tufted or woven carpeting employing polyurethane adhesive systems.
  • the secondary backing In order to achieve suitable annealing strength, the secondary backing must be in direct contact with the greige, and a sufficient amount of adhesive must be interjacent the greige and the secondary backing to ensure complete wet out of the fibers.
  • Another key property is, the fiber lock, which measures the force necessary to pull face fibers from the carpet.
  • Latex is typically applied by methods involving roll over flatbed or roll over roll processes. Regardless, of the method used, the greige is coated with an adhesive precoat of latex, and the secondary backing, also coated with latex, is married to the greige and cured.
  • latex is a popular adhesive
  • carpet prepared from latex displays numerous shortcomings.
  • the strength and hydrolytic stability of latex is less than desired, and latex is less durable over time than alternative polymer systems such as PVC plastisol or polyurethane.
  • latex curing requires the evaporation of large amounts of water during cure, a process that is both expensive and energy intensive.
  • the use of latex also hinders the effective recycling of manufacturing remnants and used carpet at the end of its life cycle.
  • polyurethane adhesives are capable of forming carpet with superior annealing strength as well as other desirable physical properties.
  • technical problems have kept it from widespread use in the industry.
  • polyurethane application from bulk troughs is made very difficult due to premature polymerization in the delivery line.
  • polyurethane is applied as “froth,” polymerized prior to application and sprayed onto the primary or secondary backing before the upstream edge of a doctor blade.
  • the delivery line becomes clogged retarding the flow of polyurethane to the spray apparatus.
  • polyurethane begins to lose its adhesiveness soon after polymerization begins unless the manufacturer controls the polymerization rate by using heat sensitive catalysts or other chemical agents designed to maintain the viscosity of the polyurethane.
  • U.S. Pat. No. 6,264,775 offers the addition of various chemical thickening agents to the polyurethane to maintain viscosity and adhesiveness.
  • Another process provides for the use of multiple applications of polyurethane to the primary backing prior to joining the secondary backing. See e.g., U.S. Pat. No. 6,299,715.
  • Still another technique disclosed in U.S. Pat. No. 6,299,715, is the application of both polyurethane to the primary backing and another tacky composition to the secondary backing prior to joining the two backings. None of these techniques have been favored over standard latex based carpet laminates, primarily due to the increased cost and complexity associated with building and using separate manufacturing lines to implement the new technologies.
  • the present invention pertains to a polyurethane carpet annealing system which discloses two unique advantages over the prior art. First it requires only a single application of polyurethane. The lower amount of polyurethane employed in a single application significantly decreases the weight of the carpet and decreases raw material costs. Second, the polyurethane is cured at ambient temperature. The absence of an oven-curing step markedly decreases the time from application of the polyurethane to product roll-up. The carpet produced by the process exhibits acceptable fiber lock and initial secondary backing adhesion without the use of large quantities of polyurethane and without the expensive heat curing step common in other annealing systems. In combination, the two advantages significantly increase the commercial utility of the product.
  • FIG. 1 illustrates a typical prior art latex-based carpet annealing process.
  • FIG. 2 illustrates a prior art single application polyurethane-based carpet annealing process.
  • FIG. 3 illustrates a prior art dual application polyurethane-based carpet annealing process.
  • FIG. 4 illustrates a prior art polyurethane-based process that coats primary backing with polyurethane and the secondary backing with a skip-coat adhesive.
  • FIG. 5 illustrates one embodiment of the present invention.
  • FIG. 1 illustrates a typical prior art commercial latex-based carpet annealing process.
  • the greige 5 with top carpet face 10 and bottom primary backing side 15 to which fiber lock adhesive is applied, is directed by rollers 20 to place the primary backing side 15 of the greige under trough 25 , which is supplied with latex through line 30 .
  • the downstream edge of trough 25 serves as a doctor blade 35 , in conjunction with plate 40 .
  • Adjusting the amount of latex applied also serves to force the latex through the primary backing 15 into the fibers. Further penetration is provided by pressure roller 45 .
  • Secondary backing 55 is supplied from roll 60 and directed by rollers 65 across wheel roll 70 , which rotates in trough 75 filled with additional latex which coats the secondary backing 55 .
  • the coated secondary backing 77 is pressed onto the latex-coated greige 80 by their travel through ligation rolls 85 .
  • the carpet then passes through oven 90 where water is removed from the latex, and the latex cures, adhering fibers and secondary backing to form a lamellar carpet.
  • FIG. 2 illustrates a single application polyurethane-based carpet annealing process.
  • the greige 5 with carpet face 10 downward is fed onto a metering plate 95 .
  • polyurethane “froth” 100 is placed on the backing side 15 using a mixing head 105 .
  • a secondary backing 55 is then applied to the surface of the uncured polyurethane 100 using a ligation roller 85 .
  • the coated and backed greige 78 is then passed through oven 90 to cure the polyurethane layer 100 .
  • the carpet may then be advanced through a trimmer 115 and finally to an accumulator 120 or roll-up area.
  • FIG. 3 illustrates a dual application polyurethane-based carpet annealing process.
  • polyurethane 100 is applied from first line 30 .
  • Doctor blade 35 in cooperation with plate 40 , limits the applied weight of polyurethane 100 and forces it into the greige 5 .
  • second line 32 which supplies additional frothed polyurethane 100 .
  • Doctor blade 36 in conjunction with plate 41 , adjusts the thickness of the deposited polyurethane 100 .
  • the second doctor blade 36 is spaced a distance away to allow enough polyurethane 100 to be deposited to temporarily bind the secondary backing 55 before curing.
  • the secondary backing 55 supplied from roll 60 , contacts the coated greige 80 below ligation roller 85 .
  • press rollers 125 Prior to entry into the oven 90 for curing, press rollers 125 assist in maintaining stable contact between the secondary backing 55 and the greige 5 .
  • FIG. 4 illustrates a polyurethane-based process that coats the primary backing with polyurethane and the secondary backing with a polyurethane adhesive.
  • the carpet is contacted with a wheel-coated secondary backing 55 .
  • the secondary backing 55 supplied from roll 60 , has been directed by rollers 65 past wheel roll 130 which rotates in trough 135 filled with wheel coating agent. Rotation of wheel roll 130 in the trough 135 coats the roll with wheel coating agent which is then transferred to the secondary backing 55 to form a wheel-coated secondary backing 140 .
  • Wheel roll 130 supplies a tacky polyurethane based coating agent which is not “self-curing” and therefore does not substantially increase in viscosity over the life of the composition in the trough 135 .
  • Wheel-coated secondary backing 140 mates with the polyurethane adhesive coated greige below roller 85 , which may be supplemented with a roller directly below, or a plate, to form a pair of ligation rollers or equivalent devices. The carpet then passes between press rollers 125 into oven 90 for curing.
  • FIG. 5 illustrates the carpet manufacturing process according to the present invention.
  • the greige 5 with carpet face 10 downward is fed onto a tenter roll 12 that directs the greige 5 to metering plate 95 , the carpet face 10 is advanced over the metering plate 95 using pulling rollers 21 .
  • a layer 100 of polyurethane polymer is deposited onto the primary backing side 15 as it passes over metering plate 95 using a mixing head 105 .
  • the polyurethane is applied to the primary backing 15 at an area concentration of about 1.0 g/m 2 to about 30 g/m 2 or in a more preferred concentration of about 5.0 g/m 2 to about 12 g/m 2 .
  • the polyol and isocyanate pre-polymer components are mechanically blown through a mixing head 105 to form the polyurethane layer 100 . This prevents the pre-polymers from contact until just prior to application to the primary backing 15 .
  • the polymerization process does not begin to occur until just prior to the exit of the polyurethane components from the mixing head 105 .
  • This process allows the relatively low viscosity polyurethane to deeply penetrate the fibers in the primary backing, resulting in excellent fiber lock characteristics.
  • a preferred method of blowing the polyurethane layer is by feeding separate lines of polyol and isocyanate components and a stream of air into a Gusmer Corporation spray attachment (model GX7-400). If the need arises a third line is available for the introduction of catalyst.
  • the spray attachment combined with the air stream provides sufficient turbulence to provide a homogenous solution of the urethane-forming components.
  • polymerization accelerates and foaming begins.
  • the thickness of the polyurethane foam may be adjusted by various means known in the art such as a doctor blade 35 or air knife.
  • the polyurethane coated greige 79 is then optionally passed across a steam box 150 .
  • Steam box 150 adds water to the reaction, to aid in accelerating the polymerization rate.
  • the steam serves to enhance blooming of the yarns passing through the primary backing for deeper penetration and assures a more level coverage of polyurethane.
  • a Fume hood 155 is placed above the steam box 150 to capture escaping volatiles released with the steam. Conspicuously absent at this stage of the process is an oven curing step.
  • temperatures are generally maintained within 30° F. of ambient temperature or in a more preferred embodiment within 15° F. of ambient temperature during the carpet manufacturing process.
  • prior art polyurethane curing processes are required to utilize heat sensitive catalysts and other chemical additives to maintain sufficient viscosities to apply the polyurethane, from various holding lines and troughs, to the backing surface. These additives necessitate a heat curing stage.
  • the coated greige 79 is rapidly pulled to merge roll 160 where the secondary backing 55 , supplied from roll 60 , contacts the coated greige 79 downstream from roller 87 . Due to the short time that elapses between the initial application of polyurethane and the merger of the secondary backing 55 with the coated greige 79 , the polyurethane possesses sufficient tackiness to anneal the secondary backing in place. The annealed carpet can then be cooled briefly 190 and rolled for storage and transport.
  • Polyurethane prepolymers useful in the practice of the present invention are prepared by the reaction of active hydrogen compounds with any amount of isocyanate in a stoichiometric excess relative to active hydrogen material.
  • the prepolymer formulations of the present invention include a polyol component.
  • Active hydrogen containing compounds most commonly used in polyurethane production are those compounds having at least two hydroxyl groups or amine groups. However, any active hydrogen containing compound can be used with the present invention.
  • At least 50 weight percent of the active hydrogen compounds used to prepare the polyurethane is a polyol having molecular weight of from about 100-400.
  • the polyisocyanate component of the formulations of the present invention can be prepared using any organic polyisocyanates, modified polyisocyanates, isocyanate based prepolymers and mixtures thereof. These can include aliphatic or aromatic isocyanates.
  • the isocyanate used to prepare the prepolymer formulation of the present invention is methyl diisocyanates such as Bayer's 142L or Dow p901 or blends of equal type.
  • Catalysts suitable for use in preparing the polyurethanes of the present invention include tertiary amines, and organometallic compounds and mixtures thereof.
  • suitable catalysts include stannous octoate, triethylenediamine, N-methyl morpholine, like compounds and mixtures thereof.
  • the catalysts do not necessarily need elevated activation temperatures or other promoters to initiate polymerization.
  • Surfactants can be useful for preparing a stable dispersion or froth of the present invention.
  • Surfactants useful for preparing a stable dispersion can be cationic, anionic, or non-ionic surfactants.
  • the surfactants used to prepare the prepolymer formulation of the present invention are silicone surfactants such as Dow Corning DC-194 or Union Carbide's L-540.
  • a surfactant can be included in a formulation of the present invention in an amount ranging from about 0.01 to about 7 parts per 100 parts by weight of polyurethane component.
  • a compound of the present invention optionally includes a filler material.
  • the filler material can include conventional fillers such as milled glass, calcium carbonate, aluminum trihydrate, barium sulfate, fly ash, dyes and pigments or fire retardants (aluminum trihydrate and Tris polyolefin glycol).
  • the filler can be present in an amount ranging from 0 to 300 parts per 100 parts of the polyurethane component.
  • any method known to one skilled in the art of preparing polyurethane froths can be used in the practice of the present invention to prepare a polyurethane froth suitable for preparing, for example, a carpet of the present invention.
