Definitions
- This invention relates to the formation of flooring backing from materials recycled from carpet and carpet manufacturing waste and to commercial carpet, carpet tile and other flooring.
- carpet, carpet tile and related textile fiber face flooring generally comprise a backing bonded to face cloth having a textile fiber upper wear surface.
- the face cloth may be yarn tufted into a tufting primary, yarn fusion bonded to a backing material, a woven or knitted fabric or a variety of other face layer structures.
- the backing and the face cloth are formed independently and then laminated or bonded together to form the final flooring composite.
- one of the face cloth or backing is formed and the other of these components is then formed on the first.
- tufted face cloth may be formed by tufting yarn into a tufting primary, and then a backing may be formed on the underside of the face cloth while the face cloth is traversed through a production line up side down.
- the backing might be formed and bonded to face cloth in a single step by positioning crumb and other backing components on the underside of inverted face cloth and then heating and pressing the resulting composite to bond all of the materials together.
- fusion of the backing layer components generally requires significant levels of heat and pressure.
- the face cloth may therefore be subjected to heat and pressure levels that crush the face cloth and otherwise compromise the appearance and integrity of the resulting flooring.
- This invention address many of the above-mentioned problems and others by providing a flooring manufacturing process that accommodates a variety of materials.
- the process provides for formation of backing and for bonding the backing to the face cloth in a continuous process.
- the backing upon formation, can be immediately laminated to the face cloth, manufacturing time and associated costs are reduced.
- backing also can be rolled and stored after production and then bonded to the face cloth at a later time.
- the process of this invention is conducive to forming backing layer from almost any type of material, particularly including recycled and waste materials, especially used carpet and flooring and carpet and flooring manufacturing waste. Use of these cheaper materials reduces both the manufacturing costs of the flooring and the amount of landfill waste and associated environmental concerns.
- FIG. 1 is a cross-sectional, schematic view of one embodiment of the flooring made according to the manufacturing process of this invention.
- FIG. 2 is a cross-sectional, schematic view of an alternative embodiment of the flooring made according to the manufacturing process of this invention.
- FIG. 3 is a side elevation view of one embodiment of the manufacturing process of this invention used to form a backing layer.
- FIG. 4 is a side elevation view of the first dual scattering unit used in the manufacturing process of FIG. 3.
- FIG. 5 is a side elevation view of the optional second dual scattering unit that can be used in the manufacturing process of FIG. 3.
- FIG. 6 is a side elevation view of one embodiment of the manufacturing process of this invention used to laminate the face cloth to the backing layer formed from the manufacturing process shown in FIG. 3.
- FIG. 7 is a side elevation view of an alternative embodiment of the manufacturing process of this invention used to laminate the face cloth to the backing layer formed from the manufacturing process shown in FIG. 3.
- FIG. 8 is a side elevation view of yet another alternative embodiment of the manufacturing process of this invention used to laminate the face cloth to the backing layer formed from the manufacturing process shown in FIG. 3.
- the flooring composite formed by the process comprises a backing 12 bonded to a face cloth 14.
- face cloth 14 includes yarn 17 tufted into tuffing primary 19.
- the backing 12 is formed of an underlying mat 16 and a thermoplastic layer 18 bonded to the mat 16.
- the composite 11 shown in FIG. 2 includes a second thermoplastic layer 20 positioned under the underlying mat 16. While the underlying mat 16 is preferably a fiberglass mat, it may be made from any material that imparts dimensional stability to the resulting flooring composites 10 or 11, including resistance to upcurl, shrinkage, and expansion, and physical integrity to facilitate the installation, use, and reclamation of the flooring.
- Layers 18 and 20 are typically PVC or include PVC.
- the layer 18 is preferably a vinyl sheet, but may be formed from any material that softens under heat and pressure to bond to the underlying mat 16, including, but not limited to, any thermoset or thermoplastic polymeric material, including, urethane, bitumen, modified bitumen, polyvinlychloride, polypropylene, olefin, polyester, polyurethane, nylon fiber and natural fiber, or combinations thereof.
- Foams and other soft or resilient materials may be used in layers 18 and 20 to provide a cushioning effect. While virgin materials may be used to form layers 18 and 20, they are preferably made from recycled materials, especially used carpet and carpet manufacturing byproducts such as carpet backing, ground carpet face yarn, edge or selvage trimmings.
- layers 18 and 20 may include fillers and other materials that do not soften under heat and pressure provided that adequate amounts of such plastic materials are included in layer 18 or 20 to achieve the desired properties in the finished flooring.
- the face cloth 14 may be formed from any floor covering material, including, but not limited to, a tufted material like that depicted in Figs. 1 and 2, fusion-bonded material, and woven, non- woven or knitted material or fabric.
- the fiber of the face cloth 14 may be formed from, for example, nylon, polyester, PTT (polytrimethyl terephthalate), PBT (polybutyl terephthalate), PLA (polylatic acid), polypropolyne, hemp, wool and other fibers.
- Layer 18 of the backing 12 and the face cloth 14 are bonded together with an adhesive 22.
- the adhesive 22 have a low melt viscosity to facilitate penetration of the adhesive 22 into the face cloth 14 with minimal pressure.
- the adhesive 22 thereby encapsulates portions of yarn 17 of the face cloth 14 to ensure bundle wrap and tuft lock.
- Suitable adhesives include, but are not limited to, any thermoplastic polymer, including hot melt, latex, ethylene vinyl acetate, acrylic, a bitumenous compound, or a rubber compound, or any combination of these materials. Additionally, anti-microbials, anti-dustmites, and flame retardants may be incorporated into the adhesive 22.
- the adhesive 22 may have any form at room temperature, it preferably has a form that facilitates application onto the backing 12 (or 21) or face cloth 14 of a continuous, even layer of the adhesive 22 with minimal amounts of the adhesive 22.
- Powder adhesive has proven particularly useful, and, for the purpose of this discussion, will be described in the embodiment detailed below to explain the process of this invention.
- the continuous manufacturing process of this invention preferably involves at least two steps.
- the backing 12 or 21 is produced in the first step (illustrated in FIGS. 3- 5), and the backing 12 or 21 is laminated to the face cloth 14 in the second step (illustrated in FIGS. 6-8).
- Granulated, preferably vinyl, pieces 24, which will form the stratum or layer 18 are first scattered onto a conveyor belt 26 using, for instance, a dual scattering unit 28.
- a conveyor belt 26 is preferably made from a heat resistant material that prevents the resulting backing 12 from adhering to the belt 26 during the manufacturing process.
- PTFE tetraflouroethylene or "teflon” coated glass fiber belts work particularly well in this application.
- the dual scattering unit 28 comprises two scattering units, one for larger granules or particles 29 and a second for smaller particles 30 (see FIG. 4).
- the scattered vinyl pieces 24 are then moved on belt 26 through an edge trimming device (not shown).
- the edge trimming device removes vinyl pieces 24 that have been scattered beyond the desired width of the backing 12. While a number of devices may be used to perform this function, a preferred edge trimming device vacuums pieces 24 that have been scattered beyond the desired width off of the conveyor belt 26. In this way, these outlying vinyl pieces 24 may be redeposited onto the conveyor belt 26 by the scattering units 29, 30.
- Conveyor belt 26 then carries the vinyl pieces 24 under a bank of infrared (IR) heaters 32 that heat the vinyl pieces 24 to a temperature in a range of 100°- 300° Celsius, depending on the speed of the conveyor belt 26 as it passes under the IR heaters 32.
- IR infrared
- Mat 16 is fed from an unwinding station 34 and positioned on top of the vinyl pieces 24 to form the bi-layered backing 12.
- the mat 16 may be heated prior to being placed on top of the vinyl pieces 24, preferably to a temperature in a range of 100°- 300° Celsius. While heating of either or both of the vinyl pieces 24 and underlying mat 16 prior to their merger is not always required or necessary, such heating facilitates bonding between the two components.
- the order of formation of the bi-layered backing 12 may be reversed and mat 16 may belaid directly onto the conveyor belt 26 and the vinyl pieces 24 then scattered directly onto mat 16.
- FIG. 5 illustrates the optional step of depositing a second stratum or layer of vinyl pieces 36 onto the bi-layered backing 12 to form a tri-layered backing 21.
- vinyl pieces 36 may be added by an optional dual scattering unit 38.
- This second layer of vinyl pieces 36 sandwiches the underlying mat 16 between the two layers 18 and 20 of vinyl pieces 24, 36.
- the resulting tri-layered backing 21 is then passed through a second edge trimming device (not shown). Incorporation of this optional second layer 20 of vinyl pieces 36 results in the embodiment of the flooring composite 11 illustrated in FIG. 2.
- Backing 12 is next fed under a second bank of infrared (IR) heaters 40 that preheat the vinyl layer 18 and mat 16 before the backing 12 is fed into the oven 42.
- IR infrared
- the backing 12 is next fed through the oven 42, which has a heating section 44 and a cooling section 46. While any heat laminating process capable of thermally bonding thermoplastic materials, including textile fibers, various thermoplastic or thermoset polymers, as well as a variety of organic materials, may be used to apply the requisite heat and pressure to the backing 12, a Thermofix® oven is particularly well- suited in this application.
- An upper belt 48 is positioned in the oven 42 parallel to the conveyor belt 26.
- the backing 12 runs between the two conveyor belts 26, 48.
- Upper belt 48 is adjustable in height to influence the thickness of the backing 12. Heat is transmitted through heat plates (not shown), through belts 26, 48, and into the backing 12 to fuse and otherwise bond the vinyl pieces 24 into layer 18 and to mat 16. While the optimal oven temperature depends upon the types of materials being heated and the speed of the conveyor belt 26, oven temperatures between 180°-250° Celsius will be suitable for most materials and belt speeds.
- backing 12 is next passed through a pair of adjustable calendaring rollers 50, 52, which are separated approximately the desired thickness of the backing 12.
- the rollers 50, 52 exert contact pressure on the backing 12 to ensure that the backing 12 exiting the rollers 50, 52 has a uniform desired thickness.
- the thickness of the backing 12 obviously depends upon the application in which it will be used, but the backing 12 may have any desired thickness.
- a backing thickness (and therefore the separation gap between the rollers 50, 52) between 0.5-2 millimeters is suitable for many applications.
- the backing 12 then passes through the cooling section 46, where cooling of the backing 12 is accomplished with cooling plates (not shown).
- FIGS. 6-8 illustrate alternative lamination processes.
- a dual scattering unit 62 first scatters powder adhesive (not shown) onto backing 12.
- the powder adhesive is scattered onto the face cloth 14.
- IR heaters 64 preheat the flooring composite 10 to a temperature in a range of 100°- 300° Celsius prior to being fed into the oven 68.
- Oven 68 has a heating section 70 and a cooling section 72.
- An upper belt 74 is positioned in the oven 68 parallel to the conveyor belt 26.
- the flooring composite 10 runs between the two conveyor belts 26, 74.
- Upper belt 74 is adjustable in height to influence the thickness of the flooring composite 10 and to accommodate flooring 10 of different thicknesses.
- Heat is transmitted from heating plates (not shown), through belts 26, 74, and into the flooring composite 10, thereby melting the powder adhesive and thermo-bonding the backing 12 and the face cloth 14 into a single laminated flooring composite 10.
- the flooring composite 10 then passes through a pair of adjustable calendaring rollers 76, 78 that apply pressure to the flooring composite 10 to facilitate bonding and gauge-setting of the flooring composite 10.
- An oven 68 temperature in the range of 150°-200° Celsius is suitable for most laminating applications.
- the separation gap between the rollers 76, 78 should be set so that the rollers 76, 78 lightly press on the flooring composite 10 as it passes to ensure adhesion between the backing 12 and face cloth 14 without crushing the face of the face cloth 14.
- a roller separation gap of between 6-12 mm is suitable for most applications.
- the flooring composite 10 then enters the cooling section 72.
- An additional cooling unit 80 may be provided to further facilitate the cooling process.
- FIG. 7 An alternative lamination process to that depicted in FIG. 6 is the slot-die process, an example of which is shown in FIG. 7.
- a liquid adhesive 90 is fed through a slot-die applicator 92 and onto the face cloth 14 being transported along by the flooring roller 15.
- the face cloth 14 is then mated with the backing 12 being transported along by the backing roller 13.
- the liquefied adhesive 90 may be contained in a tub 94.
- a roller 96 dips into the tub 94, thereby coating the outside of the roller 96 with adhesive 90.
- the outside of the roller 96 then contacts the face cloth 14 traveling adjacent the roller 96, which then mates with the backing 12.
- a control device 98 contacts the roller 96 before it applies adhesive 90 to the face cloth 14 to regulate the amount of adhesive 90 applied and thereby reduce adhesive waste.
- composite 10 is fed into an accumulator 82.
- Accumulator 82 feeds the flooring composite into a selvage and web trimmer 84, which trims the edges of the flooring composite 10 and cuts the flooring composite 10 into predetermined roll lengths.
- the flooring composite 10 is wound on a roll exchange 86 and can then be transported to a separate cutting station for cutting into flooring tiles or other modules if desired.
- Suitable conveyor belt and oven assemblies for practicing this invention can be obtained from Schott & Meissner, Postfach 1143; 74568 Blaufelden/Germany.
