Definitions
- This invention relates to a tape of the kind used for adhering a fabric to another surface.
- This invention relates particularly to a tape for transportation vehicle applications of the kind in which fabrics, such as floor carpets and galley mats, are to be adhered to a vehicle surface or to a pad on the floor surface or to some other vehicle surface.
- This invention relates particularly to a tape for transportation vehicle applications (such as, for example, aviation applications) of the kind in which flame and smoke retardant characteristics, low weight and moisture resistance characteristics, and the capability to be readily installed and removed while maintaining desired adhesive properties during normal use are impor- tant characteristics and capabilities.
- One tape that has been used in aviation applications of this kind has been a tape which comprises a cotton woven cloth tape with rubber based, pressure sensitive adhesives on the top and bottom surfaces of the tape.
- This tape has presented a number of problems and has not been entirely satisfactory for use in aviation ap ⁇ plications.
- the cotton cloth is a relatively heavy component which requires excessive weight in order to provide ade ⁇ quate strength. Cotton also tends to absorb water when exposed to moisture.
- a rubber based adhesive is a composite material which is made up of a number of substances which in themselves can cause problems.
- Rub ⁇ ber based adhesive may include in addition to the rubber, a tackifier, an antioxidant and fillers. One or more of these components may absorb moisture. A problem can also occur (over and extended time period) with oxidation which leads to loss of tackiness and subsequent brittle- nes ⁇ .
- the cotton backing and the rubber based adhesive also presents problems of flammability and smoke genera ⁇ tion.
- the rubber based adhesives can also, especially over time, become too permanent and can cause problems of leaving adhesive deposits on the aircraft floor when such tapes had to be removed.
- a rubber based adhesive can tend to delaminate from the cotton backing when the tape was removed because the cotton fabric provides a surface which is somewhat difficult for the rubber based adhesive to adhere to.
- Cotton fabric tapes also tend to absorb moisture.
- the tape of the present invention is a tape which is specifically constructed for applications of the kind in which fabrics, such as floor carpets and galley mats, are to be adhered to a floor surface or to a pad on the floor surface or to some other vehicle surface.
- the tape of the present invention is constructed for applications in which the tape must have flame and smoke retardant char ⁇ acteristics, low weight and moisture resistant charac ⁇ teristics, and the capability to be readily installed and removed while maintaining desired adhesive properties during installation, use and removal.
- the tape of the present invention incorporates a non-woven fabric substrate which will not absorb mois ⁇ ture.
- the non-woven fabric substrate is a film
- the film provides a moisture barrier, high strength at low weight, flame and smoke generation resistance and also provides outside surfaces which are smooth and have good wet out for adhering to associated pressure sensitive adhesives.
- the tape of the present invention also preferably incorporates strand reinforcement which is adhered to the substrate for providing high strength reinforcement at low weight.
- the tape of the present invention has a first, pres ⁇ sure sensitive, moisture resistant, adhesive layer.
- the first layer of adhesive is on the surface of the film on the side with the strand reinforcement which faces the underside of the carpet or other fabric and has high tack.
- the tape of the present invention has a second, pressure sensitive, adhesive layer.
- This second adhesive layer is on the side of the tape which faces the floor and is a relatively thin layer of adhesive and is formu ⁇ lated to permit the tape and all associated adhesive to be removable from the floor without leaving patches of adhesive on the floor.
- the adhesive is an acrylic adhesive and has flame retardant additives.
- the adhesive is a rubber based adhesive with suitable additives.
- the substrate is a plastic film, preferably either a polyester or a polyvinyl fluor ⁇ ide film, which has high dimensional stability in all directions, low moisture vapor transmission and low mois ⁇ ture pick up and which either has or is specifically formulated with additives to have flame retardancy.
- One or both of the outer surfaces of the film may be treated to improve the surface for adhering to pressure sensitive adhesives.
- the substrate is a non-woven fabric substrate other than a film and is constructed to have the required characteristics, particularly dimen ⁇ sional stability in all directions and low moisture pick ⁇ up and flame retardancy.
- the thickness and resulting weight of the substrate is kept to a minimum for the particular application area involved.
- the thickness of the film in aisle ways may be in the range of 1/4 mil to 1 mil.
- the film may have a greater thickness, in the range of 1/2 mil to 10 mils in order to provide increased resistance to moisture and increased resistance to puncture.
- the strand reinforcement of the tape provides in ⁇ creased strength with minimum weight. By using strand reinforcement a thinner substrate can be used with a smaller overall product weight than would be the case if the increased strength were sought to be obtained by a increasing thickness of the substrate by an amount needed to gain the added strength.
- the material or materials used in the strand rein ⁇ forcement are materials which are themselves flame and smoke resistant.
- the strands are polyes ⁇ ter strands.
- the denier and the count of the strands are selected so as to provide both bidirectional strength and also increased strength in the traffic flow direction while maintaining efficient resistance to longitudinal splitting or tearing of the tape.
- the count and denier of the strand reinforcement are also selected to provide distribution of reinforcement strength as needed while permitting the tape, if necessary, to be torn by hand without the need for using a cutting tool.
- the count and denier of the strands, particularly the count and denier of the strands running in the longitudinal direction of the tape are also selected to provide easy removal of the tape while keeping the tape from tearing -during re- moval of the carpet and associated tape.
- Both of the layers of pressure sensitive adhesive used in the tape are preferably formulated of an acrylic, pressure sensitive adhesive which is substantially resis ⁇ tant to oxidation.
- the upper layer of the adhesive has a thickness less than 5 mils, preferably less than 3 mils.
- the lower layer of adhesive is thinner and has a thickness less than 5 mils, usually less than 3 mils, preferably less than 1 mil.
- This thinner layer of the second lower adhesive provides a relatively low range of peel values (0.5 pounds per inch width to 2.0 pounds per inch width) so that the tape and associated fabric can be readily removed without leaving any tape or residue on the vehicle surface.
- the lower adhesive layer is not as aggressive as the upper layer.
- the lower amount of aggressive characteristics of the lower layer facilitates being able to peel the tape from the floor. This is due to the adhesive being remov ⁇ able and fully crosslinked.
- the higher aggressive characteristics of the upper layer make that layer more tacky and better able to ad ⁇ here to the irregularities of the undersurface of the carpet and to facilitate both initial installation and the desired stability during use.
- This adhesive is self crosslinked and improves peel over time. But the upper layer is not so aggressive as to destroy the carpet by pulling tufts while the tape is being removed.
- a silicone treated paper release liner is applied to the first adhesive layer so that the tape can be directly applied to the floor surface from the roll.
- Figure 1 is an isometric view of an aisle way in an airliner and shows how the tape of the present invention is used to adhere an aisle way carpet to the aircraft floor.
- a part of the aisle way carpet has been illustrated as rolled back to show how three tapes of the present invention are used underneath the carpet to adhere the carpet to the floor.
- Figure 2 is an enlarged plan view of a tape con- structed in accordance with one embodiment of the present invention.
- Figure 2 is a top view of one of the three tapes shown in Figure 1.
- a part of the top layer of adhesive of the tape has been removed to show details of the underlying strand reinforcement and film substrate structure.
- Figure 3 is an exploded, isometric view of the tape shown in Figure 2 with carpet and floor surface shown.
- Figure 4 is a side elevation view in cross section through the tape shown in Figure 2 and taken along the line and in the direction indicated generally by the arrows 4-4 in Figure 2.
- Figure 5 is a side elevation view like Figure 4 but showing a construction of a tape, constructed in accor ⁇ dance with another embodiment of the present invention, using a woven scrim strand reinforcement on a film sub ⁇ strate.
- Figure 6 is a schematic, side elevation view showing how two tapes constructed in accordance with the present invention are used to secure a carpet to a floor when a carpet pad or cushion is used for providing additional cushioning between the carpet and the floor.
- Figure 7 is an isometric view of a tape constructed in accordance with an embodiment of the present invention and packaged in a roll with a release liner ready for application to an aircraft surface.
- Figure 8 is an exploded view like Figure 3 but show ⁇ ing another embodiment of a non-woven substrate.
- Figure 1 the lower end of the carpet 13 has been illustrated as rolled up and back to show how the indi ⁇ vidual tapes 11 are positioned to hold the carpet in place and to show the underside 17 of the carpet which is engaged by the top surface of each of the three tapes 11.
- FIGS 2, 3 and 4 of the drawings show details of construction of the tape 11.
- the tape 11 comprises a film 21 as the non-woven substrate, strand reinforcement which comprises warp strands 23 and fill strands 25, and upper adhesive layer 27 and a lower ad ⁇ hesive layer 29.
- the fill strands 25 are adhered to the warp strands by a fill adhesive 31.
- the fill adhesive 31 is shown in Figure 4 but has been left out of Figure 3 for the pur ⁇ pose of simplifying the illustration in Figure 3.
- the release liner 43 is shown in Figures 4, 5 and 7.
- Tapes for transportation vehicle applications should provide a number of characteristics which are quite important in the transportation vehicle environment.
- Weight is always an important consideration in any product used for aviation use. Flame and smoke retardant characteristics are also quite important in aviation applications. High strength to weight charac ⁇ teristics are important. And, for use in certain areas of the aircraft, such as aisle entrance areas, galley areas and rest room areas, moisture resistant character ⁇ istics are quite important in the tape. It is important that the tape have a high degree of moisture resistance. Also, because there is a lot of foot traffic in aircraft entrance ways, aisle ways and other areas, it is very im- portant that the tape will keep the carpet in place with ⁇ out permitting the carpet to curl or slip or wrinkle.
- the wheels of the galley carts exert very high load con ⁇ centrations on the carpet and the underlying tape as the galley carts are pushed up and down the aisle ways, and the tape must hold the carpet securely in place during this kind of use. Because of the capital investment and the need for full utilization of the aircraft, the ground time of the aircraft must be held to a minimum, and this means that the time for installation and removal of the carpet must also be held to a minimum; so the tape of the present invention must permit easy and quick installation and removal of the carpet at such times as it may be necessary or desirable to remove old carpet and install new carpet.
- the aircraft floor is a structural member in the aircraft and it is therefore important that any adhesive used in the tape 11 not stick to the floor of the air ⁇ craft on removal of the tape because such sticking would require scraping of the structural floor of the aircraft.
- the tape 11 must therefore be cleanly removable from the floor of the aircraft.
- the aircraft flooring utilizes fiber ⁇ glass panels, and the tape 11 must not delaminate or cause any injury to aircraft panels.
- the tape must therefore have a band of adhesion which is large enough to keep the carpet in place but which is not so excessive as to leave any residue or damage any aircraft panel structure when it is required to remove the tape from the panel structure.
- the non-woven fabric substrate 21 com ⁇ prises a plastic film.
- the film is a polyester film and the surface of the film on the side which will face the floor 15 is a surface which has been treated to improve the compatibility for adhering that surface to adhesive on that side of the film.
- the film comprises a polyvinyl fluoride film, and in that embodiment the film is formulation modified to have retardants added to the film itself.
- both outer surfaces of the plastic film are treated to improve the compatibility for adhering to adhesives.
- the non-woven fabric substrate comprises a non-woven multi ⁇ directional, fiber fabric which is light weight, strong, and fire retardant and which has low moisture pick-up.
- the substrate is made from a material which has high dimen ⁇ sional stability in all directions so as to provide a maximum of strength and resistance to distortion with a minimum of weight for that component of the tape.
- the plastic film is made of a material which has fire retardant properties capable of making the film self extinguishing under applicable Federal aviation regula ⁇ tions such as, for example, regulation No. 25.853(b).
- the tape can comprise a film which has a thickness less than 20 mils, usually less than 5 mils, preferably 1/2 mil.
- a tape in the thickness of 1/4 mil to 1 mil can be used.
- the film may have a thickness less than 20 mils, usually less than 10 mils, depending upon the particular requirements.
- the tape 11 of the present invention preferably includes strand reinforcement associated with the sub ⁇ strate because the strand reinforcement can provide a higher amount of strength at somewhat lower weight than can be accomplished than just by increasing the thickness of the substrate.
- the strand reinforcement comprises strands which are bidirectional warp and fill strands.
- the bidirectional strands comprise a non-woven fabric in which the fill strands 25 are adhered to the warp strands 23 and to the underlying film 21 by a fill adhesive 31 which is associated with fill strands 25 as illustrated in Figure 4.
- the fill adhesive 31 is a fire retardant adhesive.
- the warp strands are selected to have a denier and a count to provide a relatively uniform reinforcement to the film and to permit the film to be slit longitudinally while still retaining relatively uniform reinforcement. That is, for example, enough warp strands are used to impart reinforcement to a number of longitudinal loca- tions extending across the width of the tape, rather than having a smaller number of larger strands which could possibly induce non-uniformity of reinforcement, particu ⁇ larly when it is necessary to slit the tape.
- the non-woven fabric substrate 22 comprises a non- woven multi-directional, fiber fabric.
- the fabric 22 can be used in place of the film 21, as shown in Figure 8, or the fabric 22 can be used in place of the scrim 23,25 and the film 21, depending on the strength required for the tape.
- the warp strands are substantially uniformly spaced and the count of the warp strand is substantially 6 warp strands per inch.
- the warp strands are approxi ⁇ mately 220 denier. This denier is large enough to pro ⁇ vide the desired strength in the longitudinal, warp di ⁇ rection, the direction of traffic flow in an aisle way, while still permitting the tape to be torn by hand, if necessary, rather than absolutely requiring the tape to be cut by a cutting tool.
- a relatively high count of warp strands also provides increased resistance to break ⁇ age at such times as it is necessary to remove the carpet and the tape.
- the fill strands are substantially 2 strands per inch and are approximately 70 denier. This relatively low number of small size fill strands has been found adequate to provide sufficient resistance to tearing or splitting along the longitudinal direction of the tape.
- the preferred material for the warp and fill strands is a polyester material.
- the strand reinforcement is made of a material or materials which are flame resis- tant and smoke resistant and which have self-extinguish ⁇ ing characteristics in the event of exposure to flame and have high tensile strength and resistance to moisture pick up.
- a woven scrim fabric as shown in Figure 5 can be used in certain applications.
- the warp strands 23 are woven with the fill strands 25.
- the adhesive for adhering the strand reinforcement to the film 21 is a surface coating of adhesive 31 instead of the fill strand adhesive 31 as shown in Figure 4.
- the other important components of the tape of the present invention are the first adhesive 27 which adheres the tape to the overlying fabric or to padding and the second adhesive 29 which adheres the tape to the floor or to padding on the floor (see Figure 6) of the vehicle.
- the first adhesive layer 27 has a somewhat irregular upper surface which basically follows the contours of the underlying strand reinforcement.
- This layer of adhesive 27 (or the film 21) also preferably has a black color for optical properties.
- the high tack of the pressure sensitive adhesive is important in order to provide improved adhesion to ir- regular surfaces, such as the underside of fabrics and good instantaneous tack so that when a carpet is rolled out it can be installed substantially instantaneously.
- This layer 27 of adhesive is formulated to have high shear strength so that the carpet will not scoot on the tape and so that any tendency of the associated fabric to wrinkle will be minimized.
- the adhesive (whether acrylic or rubber based) of this layer is formulated to have less than one percent moisture pickup and remains tacky when wet so that this layer of adhesive in combination with the film 21 provides a very effective barrier to mois ⁇ ture.
- This layer of adhesive 27 is formulated to have a moderate peel strength so that a carpet can be readily picked up (without removing the carpet tufts) when the carpet is to be removed and replaced, but so that the carpet will nevertheless stay in place during the instal ⁇ lation and use.
- the ad ⁇ hesive 27 has a thickness in the range of 2 mils to 3 mils and is a cross-linked acrylic adhesive.
- the second adhesive layer 29 is preferably a clear adhesive. It too must have pressure sensitive charac ⁇ teristics.
- this adhesive layer 29 is formulated of an ad ⁇ hesive which provides peel values that stay consistent over time and do not substantially increase or decrease while the tape is used to adhere the tape to the associ ⁇ ated fabric and the aircraft surface.
- the adhesive 29 has a low range of peel values so that the tape and as ⁇ sociated fabric can be readily removed from the aircraft surface.
- the adhesive 29 has a thickness in the range of 0.7 mil to 1.5 mil.
- Both of the adhesives 27 and 29 have sufficient moisture resistance to retain tack in the event that the overlying fabric 13 gets wet.
- the tape 11 of the present invention is, however, usable for those installations in which a padding might be desired, and the way that the tape 11 of the present invention is used in such a case is illus ⁇ trated in Figure 6.
- two tapes 11 are used to adhere a carpet fabric 13 to a floor 15 when a pad 41 is desired.
- a tape 11 is interposed in the pad 41 and a second tape 11 is interposed between the carpet 13 and the top of the pad 41.
- the pad can be either a fabric mesh (a pad in which fabric is used over foam) or a fabric pad without foam.
- the adhesives of the tape 11 provides sufficient tack for retaining the carpet in place in either event.
- the silicone coated release paper 43 shown in Fig. 4 is a kraft paper coated with a silicone coating on both outside surfaces so as to provide equal release with respect to adhesives engaged with those outside surfaces.
- This silicone treated paper is a standard product which may be obtained from any number of suppliers.
- the first adhesive layer 27 is an acrylic adhesive which had been colored with a black color and which has a fire retardant additive added to the formulation of the adhesive layer.
- the thickness of this adhesive layer is 2.5 mil and the adhesive is self cross-linked so as to provide instantaneous tack to the underside of carpet.
- This layer of adhesive has an irregular upper surface for increasing adhesion to the irregularities of the under surface of the carpet.
- the acrylic adhesive is of a type available, for example, from Morton Chemical under the trade designation Adcote 73A207A.
- the fire retardant additive is of a type available, for example, from Stauffer Chemical under the trade designation Fyrol C E F.
- the strand reinforcement 23-25 comprises polyester strands 23 of 220 denier with a spacing of 6 yarns per inch.
- the strands 25 are polyester strands of 70 denier with spacing of 2 fibers per inch.
- the adhesive 31 is a fire retardant adhesive suit ⁇ able for adhering polyester strands to a plastic film substrate and compatible with the acrylic adhesive of the first adhesive layer 27.
- the non woven fabric substrate 21 is a polyester plastic film corona treated on the surface which is op ⁇ posed to the adhesive 29.
- the film is 1/2 mil thick. This film can be bought from any number of suppliers.
- the second adhesive layer 29 comprises a clear acry ⁇ lic adhesive which has a fire retardant additive.
- the acrylic adhesive of the layer 29 is fully crosslinked so as to be removable from the vehicle floor.
- the thickness of the layer 29 is 1 mil.
- This acrylic adhesive is of the type available, for example, from B. F. Goodrich
- the tape produced in this example is particularly suited for use in an aircraft for adhering carpet to the aircraft floor in the aisleways and under seats of the aircraft.
- Example 2 The components of Example 1 were repeated except that the substrate 21 is a polyester film with a thick ⁇ ness to 10 mils and the strand reinforcement 25 is a polyester strand of 220 denier with spacing of 6 fibers per inch.
- the first adhesive layer 27 is also a clear adhesive to provide viewing of the floor surface through the tape.
- the thicker film provides durability and puncture resistance as well as an effective moisture seal.
- the strand reinforcement 23-25 is the same type and density in both directions to provide uniform strength in both transverse and cross directions.
- Example 3 The components of Example 1 were again repeated except that strand reinforcement 23-25 is a woven scrim reinforcement, as shown in Fig. 5, rather than a non- woven strand reinforcement 23-25.
- the adhesive 31 used to bond the reinforcement to the substrate 21 is applied as a coating to the substrate rather than a coating on the cross strands 25.
- Example 4 The components of Example 1 were repeated except that the substrate 21 is a non-woven, multidirectional fiber fabric as shown in Fig. 8, rather than a plastic film substrate.
- the non-woven, multidirectional fiber fabric pro- vides uniform strength in all directions.
- a suitable material is resistant to moisture pickup and is fire retardant.
- Example 5 The components of Example 4 were repeated except that the strand reinforcement 23-25 and the adhesive 31 are omitted.
- a substrate 21 should have adequate strength in the longitudinal direction to allow for re ⁇ moval of the tape without tearing.
- Example 6 The components of Example 1 were repeated except that the first adhesive layer 27 is a rubber based ad ⁇ hesive and the second adhesive layer 29 is a rubber based adhesive. Rubber based adhesives of this type available, for example from Morton Chemical under the trade designa- tion Adcote 72A209 for the first adhesive layer 27 and
