Description
The index of related application
The application's a part is for common unsettled existing resigned sequence number is 08/298,642, the applying date is the continuation application of the application of 94.08.31.
Background of invention
Traditional tufted carpet is produced by Tufting machine by a woven submissive basic substrate, be provided with on the Tufting machine a queue of pin can force carpet multifibres yarn to pass substrate and passing after hooked by a queue of hook again, then these pins again the row returns.But about 1400 such pins of horizontally-arranged on 12 feet width.Substrate must can adapt to the puncture of pin and not be damaged.Afterwards, the substrate short distance (being about 1/10 with regard to common high-quality tufting density) of advancing makes pin pass substrate again so that form the yarn tufting of next column again.Can adopt a queue of cutting knife to combine,, thereby produce velvet carpet (cut-pile carpet) so that will cut off by the tufting circle that substrate inserts with above-mentioned those hooks.For loop-pile carpet, the tufting circle does not cut.Frictional resistance remains on tufting on the substrate after pin moves on the next position.Therefore but when using as carpet, this frictional resistance is not sufficient to and tufting can be remained on original position, need apply sufficient adhesive all filaments of tufting bottom are embedded on the downside (inserting needle side) of basic substrate.Can prevent so just that in use tufting or indivedual filament are drawn out.In order to promote to stablize, harden, strengthen and to keep the tufting bottom not make wearing and tearing, at the downside of the basic substrate that tufting is arranged affix one deck second substrate also.Second substrate can or apply more adhesive with same adhesive layer and link.For cost saving, the most normal use is latex adhesive.Easy damaged not when second substrate must and be installed in shipment, carrying.
A problem of above-mentioned traditional carpet is the structure heaviness.These carpets just are difficult to install as a result, and are difficult to recycle after reaching useful life, because used many different polymer in its structure.Normally used have the tufting latex adhesive of nylon, polyacrylic basic substrate and polyacrylic second substrate.These materials are difficult to carry out so that reclaim the separation of polymer; And latex and nylon polymer are not suitable for reusing.So just cause annual millions of pounds the useless carpet landfill that goes out of use that all will have.
Past nylon (" full nylon ") carpet once often was suggested.But the nylon polymer that is used as substrate in this carpet has sensitiveness to humidity, and it is also how much relevant with variation of temperature that 4% to 10% variation can take place from tide extremely to the size of extremely dried carpet nearly along with humidity.This wet stablizing with the heat-staple problem past do not noticed suitably that this carpet with substrat structure can not often keep smooth in use.Usually the humidity that takes place when using in the family changes can cause huge warpage in carpet, mostly be the mobile place that is restricted at carpet, this restriction is owing to for example contact (situation that is routed to wall from wall) with wall, the frictional resistance that furniture produced by heaviness maintains, or is fixed on the floor or the like caused at regular intervals.Particularly can change to and be close at 100% o'clock from being close to 0% in relative humidity (RH), under the condition with higher, the stability of the carpet that uses more merits attention the temperature of family at home again.
Once the someone advised adopting light-duty carpet construction, but they use adhesive because dependence is a large amount of, so that bad operation in manufacture process, and the nylon polymer that is used as the yarn tufting usually is difficult to recycle.The machinery of this light weight construction is installed and operation is all pretty troublesome no matter be proposed to be used in, because they will handle the material of whole carpet width in the process that is connected continuously.They also often are required the yarn of decentralized supply is fed in the process, therefore need a large amount of by stages supply yarns or be deadlocked continually to change the indivedual bobbins that use up at any time.
This shows, need a kind of light-duty carpet construction, they in use size must be stable, and can easily recycle to produce useful polymer.Need the carpet of a kind of " full nylon ", they must be stable to humidity and variation of temperature in use.The method that needs a kind of simple and inexpensive is made this carpet.
The present invention just can provide this carpet and manufacture method thereof.

The enhancing filament (as glass) of strand basically to insensitive (being that thread-length does not become because of the variation of humidity basically) of humidity and this filament to the absorption of water less than 0.20%.The modulus that strengthens filament per unit density should be five times of thermoplastic resin (as nylon) as core retainer plate at least.Preferably strengthen the multifibres that filament is glass fibre, ceramic fibre or carbon fiber.Carbon fiber can be the pitch derived carbon fiber that obtains from asphalt or coal tar asphalt, or the PAN formula carbon fiber that obtains from acrylic fibers.Glass fibre can be with continuous strand formula or staple formula, the glass fibre of handy continous mode.Ceramic fibre can be used SiC fiber, SiN fiber, BN fiber or alumina fibre.Organic polymer filament with required moist stability and modulus/density also can be used.And will be appreciated that it also is separately operable.
The thermoplastic resin that can be used as the strand crust can be to be considered to basically the insensitive fluoropolymer resin of humidity as polyethylene terephthalate (PET), is preferably " Dacron " PET, polypropylene or its analog.On the other hand, the fluoropolymer resin that is used for strand also can be to be considered to resin such as the polyimides or the polyamide of moisture-sensitive basically.Best, resin is nylon 6,6 or nylon 6, and wherein nylon 6,6 is especially better.The life of these resins that reclaim or the modification of industrial waste product also can be used, and product is more easily processed and less cost.
In other embodiment, strand is also nonessential will skin/cored structure.For example, available strand with nylon, polypropylene or monofilament polyester or multifibres illustrates in Table I as following.
Perhaps, strand can be the structure of a moisture-sensitive.Term " the support strand of moisture-sensitive " means a strand, and to be 40 ℃, humidity in temperature change to 3% or more hour, the variation of its length dimension is greater than 2% from 100%.
Multifibres yarn as the tufting yarn can be used this unemployed known the whole bag of tricks manufacturing.These yarns contain the filament (fiber) of useful synthesising thermoplastic copolymer such as polyamide, polyester, polyolefin and acrylonitrile and copolymer or mixture preparation.Natural fabric such as wool also can be used.
Preferably polyamide (nylon) is chosen from the cohort with following component: nylon 6,6 or the homopolymers or the copolymer of nylon 6, contain from the sulfonation nylon 6 of the unit that its virtue bunch sulfonate or alkali metal salt are derived, 6 or the copolymer of nylon 6, contain from the nylon 6 of the unit that dimethyl-penten diamines (MPMD) and isophthalic acid are derived, 6 or the copolymer of nylon 6, contain from the nylon 6 of isophthalic acid and terephthalic acids derived units, 6 polymer, and contain from N, the copolymer of the nylon 6,6 of N '-dibutyl hexamethylene diamine and dodecanedioic acid derived units.By weight, more excellent nylon 6,6 copolymers contain and be about 1.0 to 4.0% the unit of deriving from the sodium salts of 5-sulfoisophthalic acid.
Best, polyolefin is polyacrylic homopolymers or copolymer or mixture, as if propylene/ethylene copolymer, this carry out at the same time and entrusts, sequence number is 08/419,569, to file day be in the U.S. Patent application of 95.04.10 explanation to be arranged, and mentions for reference here.
Preferably polyester is chosen from the cohort with following component: poly-(Polyethyleneglycol Terephthalate), poly-(terephthalic acid (TPA) propylene diester), poly-(butylene terephthalate) and their copolymer and mixture.Wherein poly-(terephthalic acid (TPA) propylene diester) is especially more excellent, because being used for making, it has the fiber that keeps unique carpet texture and wear resistance, these performances carry out at the same time and entrust, sequence number is 08/268,585, file day and explanation to be arranged, mention for reference here in the U.S. Patent application of 94.06.30.
These polymer are used to prepare molten polymer or solution, use industry technique known then, as if those illustrated technology in the application of mentioning in the above, they are extruded by spinning head becomes filament.Molten polymer or solution also can contain additive, as UV (ultraviolet ray) stabilizing agent, deodorant, flame retardant, delusterant, antiseptic etc.
In some cases, the multifibres yarn that contains these filaments is coloured to the tufting yarn into the band look subsequently.These yarns can be described as pre-yarn dyeing, because they were painted before making carpet.
In other cases, can use a kind of method that is called solution-dyed to make the filament of band look, and then make the band look tufting yarn of multifibres with them.In general, this method comprises pigment or dyestuff is joined in the liquation or solution of polymer, and then makes it pass through spinning head the mixture extruding.In the article of relevant carpet, these yarns also are known as pre-yarn dyeing because color before carpet is made tufting or other add yarn to before being shaped and get on.
Pigment can add the mixture that becomes in the pure foam with above-mentioned additive to, perhaps becomes concentrate, and wherein pigment is permeated in the matrix of polymer.With regard to the color concentrate, but one or more pigment all disperse in polymer substrate, in this matrix, also can contain just like lubricant and delusterant (TiO
2) some such additives.So color concentrate and the mixed with polymers of making filament, and mixture is spun into band look filament.For example, United States Patent (USP) 5,108,684 just once disclosed this process, mentioned for reference here.Pigment is permeated in the trimer of a nylon 6/6,6/6,10 and is made into trimeric band granules of pigments in this process.These particles refuse or " slowly descend " then have in the nylon 6 of identical or larger amt to one, thoroughly mix to form the regelation of uniform disperse liquid and also make particle.The color concentrate of Xing Chenging mixes with a nylon copolymer that contains its aromatic sulphonate or alkali metal salt then like this.Again the fusion mixture of this nylon is spun into antipollution and with the nylon filament of look.
Typical way is that the polymer of fusing is expressed in the cover that quenches by spinning head in the nylon filament manufacture process, the cooling air is blown on the filament of heat of this new shaping.The shape of cross section of filament depends on the design of spinning head.Best, filament has the cross section of trilobal, and its adjustment rate (modification ratio) (MR) is about 1.0 to 4.0.The gloss (gloss of filament be result from reflection of light) that the cross section of filament has influence on tufting is concealed performances such as earth, bulk and feel.Filament can contain the hole of running through its axle center, and as United States Patent (USP) 3,745, No. 5,230,957, No. 061 or United States Patent (USP) are illustrated.In filament, exist gloss and the earth that the hole can have influence on the tufting yarn and conceal performance.
Filament is transferred the roller tractive and handles by quench zone and by calender and obtain spin-drawing fineness.Pass through the draw roll of heating then.Filament can be curled and make the bulk yarn with continuous filament (BCF) subsequently.The three-dimensional curve that these yarns have distribution at random curls.Perhaps, filament can be curled and be cut into short section and make staple.As United States Patent (USP) 3,186, No. 155 or 3,525, No. 134 illustrated bulk methods of heated air jets of United States Patent (USP) can be used to make yarn crimp and bulk.In general, for the purposes of the present invention, the bulk crimp extension rate (BCE) of each yarn is about 20% to 50%, and the DENIER fineness (dpf) of each filament is about 16 to 25.To good loose, the entanglement filament, cast napping tufting band carpet, BCE% can tend to the upper limit of above-mentioned BCE% scope., cutting napping tufting band carpet excellent handle, doubling twisting to having, BCE% should be preferably 31% to 43% in 27% to 49% scope.To velvet, fulling milling is had the cutting frieze carpet of good drag, BCE% can tend to the lower limit of above-mentioned BCE% scope.
If this yarn is intended for use to cut napping tufting band carpet backing and installation system, these " single " component yarn twisteds can be formed together the multifibres yarn of doubling twisting so.The multifibres yarn of this doubling twisting is this technology of component yarn two or more, for example at United States Patent (USP) 5,263, in 308 two step twisting/stranding methods of explanation or directly the stranding method twist and synthesize hawser and constitute.Doubling twisting can be unidirectional or twisting can have the direction of alternately changing, and is as at United States Patent (USP) 4,873, illustrated in No. 821.For the purposes of the present invention, it is preferably that total DENIER number of ply-twisted yarn is at least 2000, is more preferably in about scope of 2400 to 3100.Ply-twisted yarn is preferably a double strand yarn, and its twist is changeed in the scope of per inch (tpi) about 3 to 5.Perhaps, this yarn can be read by vacation or entwine with air flow jetting, and this will decide according to required carpet construction.
If doubling twisting multifibres yarn is configured, this yarn just can be by " distortion " so, and method is to make this yarn by a stuffer box, and this yarn is stressed within it, and indivedual filaments are folded and are crooked.This yarn also available heat is handled the twist of setting in the yarn.If this yarn plans to be used in the carpet backing and installation system of cutting napping, will carry out the heat of this twist so and set.These technology also all are known in the industry.For example this yarn can be handled " Superba " Continuous Heat fixing machine of yarn or one with xeothermic " Suessan " machine of handling yarn with the supercharging saturated vapor by one.Just can these yarns be used for constructing tufting band carpet sub-assembly then according to the illustrated method of this paper.
In final carpet sub-assembly, tufting can have various forms, for example cast fine hair or cutting fine hair.The feature of cast fine hair tufting is the cast that yarn Shu Weiwei cuts, as being 08/331,074 in sequence number, filing day for illustrated in the U.S. Patent application of 94.10.28.Cutting napping tufting can cut the cast of tufting yarn and obtain, or the most handy process shown in Figure 1 is made.
The final also available anti-pollutant of tufting band carpet sub-assembly is handled, so that give the napping yarn opposing ability that ACID DYES is polluted.Anti-pollutant for example can comprise the phenol formaldehyde of sulfonation or the aromatic vinyl maleic anhydride polymer of naphthols formaldehyde condensation products product and hydrolysis, and is as United States Patent (USP) 4,925, illustrated in No. 707.The agent of the also available antidusting soil of tufting band carpet sub-assembly is handled so that give the ability of napping yarn opposing dust.The agent of antidusting soil for example can comprise the composition of fluorine chemistry, and is as United States Patent (USP) 5,153, illustrated in No. 046.
Best, the tufting yarn contains the filament of being made by polymer, can dissolve etc. with heat fusing or solvent and be bonded to, thereby the polymer that was used for strand and tufting originally just there is way that strand and tufting are bonded together, and no longer need to add other adhesive material on the selected polymer of strand.But adding a spot of adhesive material strengthens bond vitrified and may need in addition.Preferably tufting polymer and strand polymer are same polymer or belong to same polymer group.
The direction (XD) of promptly crossing machine on the direction that substrate base layer 218 must be vertical with the tufting band goes up " moist stable ", it can be not necessarily moist stable on the direction (MD) that on the direction (T/SD) of tufting band is machine, term " moist stable " means, being 40 ℃, humidity in temperature changes to 3% or more hour from 100%, at concerned direction, that (XD) or (MD) goes up length dimension is changed to 2% or littler.
" substrate base layer " can be any suitable flaky material, for example can comprise as if fabrics such as felt, weaving goods, non-woven product, knitwear and flocculate reach diaphragm, as film slat fabric.
Term " moist stable substrate base layer " means a kind of like this substrate base layer, changes to 3% or more hour in 40 ℃ of temperature, humidity from 100%, and this basic unit is changed to 2% or littler in machine direction (MD) and the length dimension that crosses on the machine direction (XD).The variation that is preferably in length on MD and the XD both direction is 1% or littler, and this point is particularly important when this basic unit is used to the large tracts of land carpet and is fixed on the floor.The suitable thermoplastic polymer that is used for making moist stable substrate base layer can be a pair of basically to the insensitive polymer of humidity,, is preferably " Dacron PET ", polypropylene or analog as polyethylene terephthalate (PET).
Perhaps, the polymer of substrate can be a moisture-sensitive basically, but at least on the direction of XD with basically the insensitive enhancing filament of humidity being made dimensionally stable.So form so-called " substrate base layer of moisture-sensitive ", this term means a kind of like this substrate base layer, and being 40 ℃, humidity in temperature changes to 3% or more hour, the length dimension of substrate on machine direction (MD) changes greater than 2% from 100%.The polymer of some moisture-sensitive can be used to make this substrate base layer, comprising polyimides and polyamide.Preferably this polymer is nylon 6,6 or nylon 6, and wherein nylon 6,6 is suitable especially, and product processing and less cost easily still can be used and can be made to the life of these resins of recovery or the modification of industrial waste product.
In order to reach required moist stability and structural stability in the carpet backing and installation system of completion, substrate base layer can strengthen with strengthening filament or strengthening lax cord.The enhancing filament of substrate basically to insensitive (length that is filament does not become because of the variation of humidity basically) of humidity and this filament to the absorption of water less than 0.20%.The modulus of enhancing filament per unit density should be five times as the thermoplastic resin of substrate at least.Preferably strengthen the multifibres that filament is glass fibre, ceramic fibre or carbon fiber.Carbon fiber can be used the carbon fiber from pitch that obtains from asphalt or coal tar asphalt, or PAN that obtains from acrylic fibers or carbon fiber.Glass fibre can be continuous strand formula or staple formula.The glass fibre of continous mode preferably.Ceramic fibre can be SiC fiber, SiN fiber, BN fiber or alumina fibre.Organic polymer filament with required moist stability and modulus/density also can be used.
When on the end face of 8 * 8 the lax cord that above-mentioned substrate preferably is bonded to for the non-woven nylon fabrics by " Sontara " of 1 ounce per square yard that a multifibres glass fibre by 1000 DENIER constitutes and the bottom surface, preferably be covered with on the cylinder 210 of Fig. 3 so that delay from by of the heat flow of the carpet element of ultrasonic heating to cylinder by a heat insulation layer.It is believed that to do like this to make ultrasonic heating more effective.A kind of such cover layer that has been employed be by the CHEMFAB company manufacturing in Merrimack place, NH state, model is glass fibre senior serial 350-6A, that be coated with apposition TFE.Acrylic acid adhesive can be used to this cover bonding on metallic cylinder.The TFE surface can make substrate base layer can not adhere on the cover layer.Tectal thickness can provide some elasticity to drum surface, concentrates and just can reduce owing to those may produce stress that the change in size in the element of " focus " causes when being bonded to the tufting band on the substrate like this.If adopt a kind of thicker substrat structure, this structure can provide certain load to distribute when bonding, if perhaps the tufting band passes through the speed of transmitter greater than about 10 yards/minute, making to have significant heat to be delivered on the cylinder in this effective time, and a kind of so like this cover layer can no longer need.
Fig. 5 is a moist stable carpet (making on the device of Fig. 3) from perpendicular to cylinder axis and be parallel to the typical part end-view that direction that tufting extends axis is seen.Each bar cutting tufting band 45a-h has a plurality of filaments bundles or tufting is fixed on the support strand 32.For example, filaments bundles 46 is bent to " U " shape, should " U " shape is by a pair ofly 224 protruding upward from the bottom surface, sentencing the distance 226 isolated tuftings of holding up 52 and 54 in adjacent floor each other and form.Each filaments bundles has an intensive filament part 62 to bond together mutually, is fixed to support on the strand 32 bottom side faces.Each filaments bundles is at bottom and acute angle of dense formation.The width 74 that supports strand is equal to or less than the distance of holding up between the tufting two.By previously selected distance, as 226 spaced apart, this distance is decided according to required tufting density on the carpet between the tufting band.The tufting band is bonded on the surface 228 of substrate 218 along its length.In an illustrated embodiment, strengthen and support the inboard that strand 32 is bonded in " U " shape tow, and the bottom of " U " shape tow that the bottom side of tufting band promptly bonds is glued on the surface of substrate.At another embodiment, strand can be bonded in the outside of " U " shape tow, and strand will be glued on the surface of substrate when being attached to the tufting band on the substrate like this.
Best, tufting band or fine hair product have support strand and a plurality of tow that is made of thermoplastic polymer that a surface is made of thermoplastic polymer.Each tow forms a pair of tufting, the tufting of said centering protrudes upward at angle and therefrom in bottom bend, form a spaced apart distance at place, contiguous said bottom between this a pair of tufting, each said tow has dense an of filament that links together and is being attached on the said bottom on the surface of supporting strand, binding is to finish by the fusion of the thermoplastic polymer that supports strand and filament, and the width of said support strand is equal to or less than the distance between the internal tufting of said tufting.
Importantly the tufting band must carefully direct on the cylinder 210 and deliver under the ultrasonic adhering device 216.Fig. 6 is the close-up view of Fig. 3 part, and the band of snag shown in the figure 45 is tensioned and guiding device 214 directs on the cylinder 210 that covers with substrate 218.Ultrasonic adhering device 216 has at least one ultrasonic transmitter 230 and ultrasonic drivers 232, and they are contained in one flexibly on the carriage 234, and this carriage allows transmitter and driver is diametrically opposed moves freely in cylinder.There is an arm 236 to allow on the carriage 234 with weight, as 238 interpolations thereon, so that the control transmitter is applied to the power on the tufting band.Tensioning and guiding device have regulating wheel 240 and 242, propelling sheave 244, the guide channel 245 of V-shaped groove and other guide members that can see preferably in Fig. 7 and 8.It is also clamped that V-shaped groove in the regulating wheel 240 and 242 can make the tufting band be kept upright, and makes the magnetic torque of regulating wheel can resist the pulling force of rotor to the tufting band, thereby apply tension force.The magnetic regulating wheel can be from the NC state, the TEXTROL company in Monroe place buys.The tufting band is at regulating wheel 242 and also have and reversed 90 degree between the propelling sheave 244 of V-shaped groove.Tensioning and guiding device 214 and adhering device 216 all are contained on the frame member 246 of walking slide 212.
Fig. 7 is the view that the 7-7 line is looked from Fig. 6, the other the details how band of tufting shown in the figure is guided.Importantly the upright tufting of the tufting band of the vicinity on cylinder do not entered, to be bonded to below tufting band on the substrate on the cylinder is rolled in.It is also important that the tufting band that enters when the location its tufting must be upright and strand must be directly under ultrasonic transmitter.In order to reach these purposes, in Fig. 7, there is a guide bar 250 to be contained on the frame member 246, this bar is followed the gabarit of cylinder and near substrate, and is pressed on from side on the tufting of setting of tufting band 45j so that block them and makes with tufting band 45k that enters and ultrasonic transmitter 230 and separate.Have a guide plate 248 to be contained on the guide bar 250 and be placed near the local of substrate 218 and also with the tufting band 45j that has bondd at angle.Other has a guide bar 252 to be contained on the frame member 246 and the place that is placed near the tufting band that enters comes under the transmitter 230 it so that the tufting of holding up is kept upright and assists to guide the tufting band 45k that enters.Fig. 8 is the 8-8 line is looked from Fig. 7 another view, and guide bar 250 and 252 is just in time in the front of transmitter 230 at that time.Being guided of tufting band 45j and 45k makes tufting band 45k when bonding, the unlikely bending of tufting of tufting band 45j and wrapped up in and be pressed under the transmitter 230 or between tufting band 45k and substrate 218.In order to help that the tufting band is aimed under transmitter, the first guide margin 254 (Fig. 7) of transmitter 230 is made into the strand that arc and this edge and the formed gabarit receivability in base directly contact with irradiator surface.When strand surface when being oval (with yarn Shu Lianjie after), these transmitter limits will form the curved surfaces of an indent, these lower surface 256 places in Fig. 8 can see.Can help on the surface that transmitter has this gabarit during with high energy vibration strand is remained under the transmitter and do not skid off from this position.
Fig. 7 also illustrates another ultrasonic transmitter 258.When will be with at a high speed, as if about 10-25 sign indicating number/minute the tufting tape speed, when being assembled to the tufting band on the substrate, and when needing high reliability when boning, second transmitter 258 needs.258 of transmitters thereby still are in hot in the time will being launched device 258 bondings from the tufting band 45k of transmitter 230 near transmitter 230.The mode that just can partly accumulate of heating is carried out and the required gross energy that bonds can be shared by two transmitters like this.So just can under the fast state of the high binding of needs energy, operate.Under the low speed situation, second transmitter 258 can be used for " again link " tufting limit and improve the reliability that links missing because connecting area may be launched device 230 sometimes effectively.Two transmitters also can be shared out the work and helped one another, transmitter 230 can be used to make tufting band location exactly with low vibration and strength, and transmitter 258 can be used to link the tufting band securely with high energy and power, and the tufting band does not just have the problem of moving about below transmitter before binding like this.The technology of this two transmitters can also be used to the napping yarn is attached on strand yarn, particularly under situation at a high speed.
Other linking methods except ultrasonic bonding also can be used to the yarn bundle is attached on the strand and with the tufting band and are attached on the substrate.This method can be that solvent links or hot link, for example, uses a hot pin, or the combination of some solvent, heat conduction and ultrasonic binding.Though way is no longer in addition adhesive material to be added on tufting band or the substrate to link when being attached to the tufting band on the substrate preferably, scope of the present invention still is included in adds adhesive in the connecting area so that link between the thermoplastic polymer inequality or strengthen ultrasonic binding having.Adopt the binding of adhesive also available above-mentioned, await the reply simultaneously, sequence number is that illustrated method is carried out in 07/017,162 the U.S. Patent application.Must be noted that when adopting a kind of adhesive components of interpolation the pattern of this adhesive and employed quantity must not damage the stability of final sub-assembly to humidity.
When the device of application drawing 1 and 3, be fed on the axle 30 from the yarn bundle in yarn source 22 with from the strand of roller 33, there strand along ridge 40 advance and arrive pass on and tensioning sub-assembly 206 in driven roller 201.Yarn bundle 20 is wound on axle and the strand and is attached on the strand so that make tufting 45 with ultrasonic transmitter 42.The tufting band passes equipment and comes on the cylinder 210.211 bindings of substrate 218 usefulness adhesive tapes also are wound on the cylinder, also form an abutment joint by cutting, use adhesive tape 213 stickers on one's body certainly, as shown in Figure 7.The termination of tufting band is passed below transmitter 230, and if utilize transmitter 258 also to pass below transmitter 258, the blended rubber band sticks on the substrate of cylinder 210 ultra-Left ends, and slide 212 is positioned in the there and sets out so that begin.Now just can begin rotating cylinder and give the ultrasonic transmitter energy supply so that the tufting band is attached on the substrate; Cylinder 210 is as the anvil block of ultrasonic pressurization at that time.Slide 212 usefulness gears and being rotatedly connected of cylinder be, slide moves a required pitch when making cylinder rotate a week, for example is about 0.2 ", make the tufting band advance and on the substrate of cylinder, form the spiral arrangement of a tufting band like this along cylinder.When slide was covered all distances and come the cylinder right side, process promptly stopped ending, and the carpet that is wound on the cylinder is cut open along the adhesive tape seam of substrate, so just can remove from cylinder.So this process can repeat.For speed in the control procedure and tension force, the speed of cylinder 210 can be kept constant, and the speed of tufting band driven roller 201 can change among a small circle so that the tension force that tensometer 211 is monitored is kept constant.Simultaneously strand passes on the speed of roller sub-assembly 207 and also can change among a small circle so that the tension force that tensometer 209 is monitored is kept constant.
Though the tufting band that the system that is used for making carpet shown in Figure 3 just reels single, reel many tufting bands and be provided with a ultrasonic transmitter but scope of the present invention comprises with the very near blade of many distances, can be only with a single ultrasonic energy supply device many tufting bands that bond simultaneously.A plurality of thisly have mutliblade transmitter and can arrange along cylinder, and therefore numerous carpets that the tufting band can once all be linked and complete need only cylinder be done a few complete rotation and just can be made soon.
Though automatically the tufting band is combined to the raised surfaces sub-assembly that the system on the substrate has drawn and made shown in Figure 3 being used for, its substrate be placed on that inboard, tufting are placed on the outside and ultrasonic energy to be top side from substrate apply.But to be about to that tufting is placed on the inboard and substrate is placed on the outside also be possible to structure in contrast to this, and this moment, ultrasonic energy applied from the dorsal part of substrate.Figure 10 illustrates the schematic diagram of another embodiment, wherein has a continuous spiral rib to be used for supporting tufting band 284 on the surface of cylinder 280.Be provided with in the both sides of rib 282 at interval, as 286 and 288 so that admit tufting.Also has a groove 290 on the rib so that admit strand and prevent that the strand slippage from coming in the interval of intercostal.Tufting band 284 will be under tension force along cylinder be wound on the helical rib and with substrate without any binding.Deliver to substrate 292 on the cylinder then and be wound on the tufting band and fixed with adhesive tape.The ultrasonic transmitter 294 that span is several ribs can be used to gradually substrate is bonded on the tufting band, and cylinder is as long as just can be bonded to the other end from an end of cylinder in revolution week.Along the axial incision of cylinder, raised surface structure or carpet just can take off and launch to shakeout then for substrate that combines and tufting band.
Though the system of the batch production process that is used to make the carpet sub-assembly has been shown in Fig. 3 and 10, but also comprising with winding process, scope of the present invention makes a carpet continuous on length, wherein in order to reach the width of whole carpet, have abundant tufting band to be fed on the cylinder, and cylinder is used as anvil block in this process and transport roller.Substrate is as long as part is wound on the cylinder just enough with a plurality of ultrasonic transmitters many tufting bands that bond.Tufted face is outside cylinder in the embodiments of figure 3, and an available transmitter with a plurality of blades once links many tufting bands.In the embodiment of tufted face shown in Figure 10 in cylinder, the tufting band is as long as part is wound on the cylinder, cylinder can have a plurality of parallel ribs or disk (rather than a continuous spiral rib) to support all tufting bands, and these tufting bands can bond by a plurality of transmitter, and each transmitter is all crossed over several ribs.In both cases, the tufting band all can be by the online supply of a plurality of axles, and perhaps the tufting band can be made into off-line, supplies by roller or canister.
Raised surfaces part shown in Figure 5 can provide a very light carpet backing and installation system.Traditional cutting napping tufted carpet is together with the essential latex adhesive and second substrate, and with regard to the carpet (yarn is heavy) of 30 ounce per square yard, about 50% weight is on the tufting yarn, and about 50% weight is on substrate and latex.The important of lightweight carpet about 75% of the present invention is on yarn, has only 25% to be on substrate.To have one contain about 120 square yards of carpets, density is the typical floor covering of 30 ounce per square yard, approximately many 200 pounds of the floor coverings that the volume anharmonic ratio of traditional carpet is made by the present invention.With regard to traditional carpet speech, this can make shipping charges higher, install more effort and damage and more wastes during landfill at carpet.The latex that adopts in traditional carpet is not only gained in weight, and extremely difficulty is separated with the nylon veil with mechanical means, and also extremely difficulty is separated with nylon polymer with chemical method, so the recycling of nylon is made us stepping back.And nylon veil of using in carpet of the present invention and nylon sock can both easily be recycled and can not strengthened filament by glass fibre and cause chemical contamination.
Tufting band carpet of the present invention can carry out bulk after combination.This bulk carpet that makes has bigger covering power.The napping yarn can be further bulk owing to the napping of heating tufting band carpet.Just once this bulk operation was described in the U.S. Patent application that awaits the reply at the same time, be entitled as " method of bulk tufting band carpet ", mentioned for reference here.This operation is placed on tufting band carpet on the tenter and makes it pass through a stove, makes its cooling then with a thermal air current heating napping yarn that flows fast there.Under the situation that adopts nylon 6,6 multifibres napping yarns, the temperature range of hot-air is about 90 to 150 ℃, and this can make the temperature of whole tufting filament bring up at least 90 ℃.
The present invention also can be used to be manufactured on the moist stable carpet backing and installation system that does not have nylon to participate in some element or any element.For example, moist stable substrate can be with traditional polypropylene substrate, and polypropylene is a kind of moist stable polymer, and the available a kind of hot melt adhesive of the tufting band of nylon is bonded on the substrate.The fusing point of adhesive is higher than the fusing point of nylon tufting and is higher than the fusing point of polypropylene substrate so that make the carpet element that some fusing be arranged and obtain good bonding.Because the fusing point of nylon is than polypropylene height, the adhesive of heat should at first be applied on the nylon, makes it do of short duration cooling then before the contact polypropylene.That can do that this adhesive uses is PEEK (polyether-ether-ketone) or polyimides adhesive.Also can adopt a kind of low-melting adhesive to make its filament mobile throughout and that mechanically be engaged in tufting band and the substrate reach suitable binding.This adhesive can be traditional hot melt adhesive of being made by the copolymer of nylon.In Fig. 6, adhesive can be applied to the bottom of tufting band on the position of guide plate 245.Also can without hot melt and with a kind of curable adhesive,, the tufting band can be maintained on the position of the substrate on the cylinder until till the adhesive solidification as long as this adhesive has enough viscosity as epoxy adhesive.Heat can be applied on the carpet on the cylinder so that making to solidify accelerates, so also can help to make tufting bulk.In order to reuse the carpet element, should make adhesive softening by heat or chemicals, so that the tufting band is peeled from substrate.Different polymer elements separately just can easily be repeated to utilize.
Following Table I illustrates the host material (matrix) of some combination of the carpet sub-assembly that can illustrate that humidity of the present invention is stable.Abide by guideline given here, also might make other combinations with other polymer.
The moist independent binding glue of the illustrative combination of materials tufting of carpet element band (the TS)-tufting N N N PET PP N N N-strand N/G N/G N PET PP N N N/G substrate-XD N/G N/G N/G PET PP PP/G PET/G PP-MD N/G N N/G PET PP PP/G PET/G PP nothing of stablizing of Table I has stick (TS links on the substrate)
(annotate: N=nylon; G=glass; The PET=polyethylene terephthalate; The PP=polypropylene; The N/G=nylon jacket coats the filaments of glass core; PP/G=polypropylene cover coats the filaments of glass core; PET/G=polyethylene terephthalate cover coats the filaments of glass core).
When the material of humidity is stable and moisture-sensitive combines when reaching the stable raised surface structure (tufting band carpet sub-assembly) of humidity, to structural detail, have three vital points to need to consider as strand and substrate, that is: 1) individual elements is to the response of humidity; 2) rigidity of individual elements on longitudinally or in the plane; And 3) the required response that reaches of composite construction to humidity.When the element of a moisture-sensitive and a moist stable combination of elements, composite component is determined the available composite design of the response of humidity is theoretical.Basically, the moist stable element and the ratio of rigidity of moisture-sensitive element, for example substrate is compared with strand, must can be regulated according to experiment then greater than the value that can estimate.
Ratio of rigidity can be represented by following formula:
S
b/Ss＝(Es-Ec)/(Ec-Eb)
S in the formula
bBe the rigidity of each width increment of the stable element of humidity (as substrate),
Ss is the rigidity of each width increment of moisture-sensitive element (as strand),
Es is the maximum strain that is caused by humidity of strand,
Ec is the maximum strain that is caused by humidity of the composite carpet structure per unit width that is associated with an independent strand,
E
bThe maximum strain that causes by humidity for the substrate per unit width that is associated with an independent strand.
Notice that Ec always should drop between Es and the Eb.The nylon sock that strengthens at the glass of a nylon strand that does not strengthen that adopts an Es=0.03 and an Eb=.005, and in composite construction during the desirable strain Ec=.01 that is caused by humidity, ratio of rigidity will be 4.That is to say, substrate needs the rigidity that is about 4 times of strands.The DENIER number (fineness) of regulation strand and be used for making the polymer of substrate, the DENIER number of so required enhancing filament just can calculate and can be used as the starting point of experiment.Other parameters all will influence final composite performance as the tensile stress in the polymer of interelement bondability, element, polymeric additive etc., perhaps need the rigidity of element is made some adjusting in order to reach required composite performance.
Of the present invention tufting is attached on the strand formed the tufting band, is attached on the substrate and the carpet sub-assembly of making also has some other variation again.When for many yarns of yarn source 20 supplies, be wound on the axle 30 as 20a and 20b and them, in the time of as shown in Figure 1, the variation of yarn might be spread all on the face of whole carpet in the mode that control is arranged.Though the variation on laterally (XD) all is possible concerning traditional and two kinds of situations of the carpet tufting band, as long as take next bar tufting band to from a strand to next bar strand or from a tufting on the XD direction, it is just passable to do some variation on the yarn bundle.But tufted carpet traditional on the MD direction can not be made variation, because it just upward repeats to introduce an independent and continuous strand with straight line or meander line in the machine direction (MD) of carpet.For example perhaps need on the face of whole carpet, introduce a kind of special effect once in a while.This effect can be a kind of yarn, a kind of anlistatig yarn, a kind of antibiotic yarn with look or a kind of have the yarn of other chemical characteristics, a kind of few yarn of spending, a kind of yarn with different tissues, the twist, fineness, fineness, or the like.For example, the yarn of the tufting band that is supplied to can have three yarns and wherein have only one to be the yarn with required effect, and two tufting bands that are combined on the substrate that are close to can not have this effect yarn fully.Effect just can sparsely be distributed on the MD and XD both direction of carpet like this.
Consult Fig. 9, tufting band 260 has 1/3 napping yarn, as is decorated with hatched yarn bundle 262a and 262b contains antistatic filament.Tufting band 264 and 266 does not contain any yarn bundle that has antistatic filament, and tufting band 268 also contains antistatic filament at the napping yarn, as is decorated with hatched yarn bundle 270a and 270b.The effect yarn is controlledly spread on the face of carpet of the present invention on XD and MD both direction.
In the carpet sub-assembly, adopt continuous strand that carpet of the present invention might be increased to change and this is impossible in traditional tufted carpet, unless the operation of after carpet is made, spending much to increase in addition.For example when making strand, just can in the heart yearn at strand antistatic filament be mixed with glass fiber filaments, antistatic filament is incorporated into some or all tufting bands support in the strand.This will combine with the antistatic filament in some or all tufting yarn bundles, and can be the antistatic property that computer floor or similar applications provide reinforcement, is vital because gather low electrostatic potential in those places.Antistatic filament in all strands can ground connection.
Consult Fig. 9, the tufting band 260 that has antistatic tufting yarn has antistatic filament 272, and the tufting line 268 that has an antistatic tufting yarn has antistatic filament 274.These filaments can extend across the width of carpet continuously, and as appreciable in the drawings, the filament 274 of tufting band 268 can be up to its opposite end 276.The two ends of filament 274 can ground connection so that get on to destatic from carpet better.
One side introducing one continuous electric wire or optical fiber in the young bundle of the glass fibers of some or all tufting bands are also may be by strand with the be sent to another side of signal from carpet.If electric wire, it just can be brought into play as same antenna, one side electromagnetic shielding or tracker wire function so that be used for guide an automated belt wheel dolly make it on the carpet surface predetermined path from the another side that drives towards of carpet.A kind of so automated vehicle can be a vacuum cleaner, and it can cross carpet so that clean automatically back and forth.Signal also can interrelate with electronics toy control loop and maybe can only arrive in some part in room so that be used for limiting in all parts that toy enters into carpet.If adopt in strand, and coated polymer is different from the little insulated electric conductor of the polymer of strand, one side this electric wire also can be used to safely with the be sent to another side of electric power from carpet so.Those skilled in the art can also see that obviously those were other possible variations on effect and function originally concerning tufting band carpet sub-assembly when using this explanation.
The present invention further illustrates with following example, these exemplary application below test method.But these examples should be as limiting the scope of the invention.

Example
The structure of nylon tufting band carpet
In the Table II below, the tufting band carpet that cuts sample has solution dyed nylon 6,6 veils, adopts the ultrasonic energy that is about 48 watts/strand that its fusion is connected and adheres on nylon 6, the 6 support strands with the glass fibre enhancing.Nylon 6,6 veils are that the yarn of dying Qiu Xiangse, class of trade (DSDN) by the yarn thigh of two 1235 DENIER, before spinning is made, this yarn can be buied from E.I.Du Pont Company, and the twist after this yarn doubling twisting and the heat setting is about 4tpi (commentaries on classics/inch), and total DENIER number is about 3100.The BCE% of the component single thread of ply-twisted yarn is about 31, and dpf (filament denier) is about 19.The DENIER number that supports strand is 3900, and glass is .13 to the nylon ratio.Nylon 6,6 veils with 12 tuftings right/density of inch is placed on the strand and cuts to the napping height that forms the .5 inch.The tufting band with ultrasonic energy bond vitrified to a piece by nylon 6, on the substrate that 6 Sontara and glass fiber laminate constitute, this substrate has one by nylon 6, the upper strata of 1 ounce per square yard that 6 Sontara constitute, a middle level that constitutes by the sparse cord of glass fibre, this cord is in the MD direction, and per inch has 6 strands, and the intensity of every strand is 8 pounds; In the XD direction, per inch has 10 strands, and the intensity of every strand is 16 pounds, and is coated with acrylic acid adhesive, also has a bottom by 1 ounce per square yard of nylon 6,6 Sontara formation.
The tufting band is bonded in heavily about 25 ounce per square yard of the yarn face of making carpet on the substrate with the density of 5 strands of per inch, and used ultrasonic energy is 93 a watts/tufting band.Tufting band and carpet are to form the banded speed that forms on the module to be about 10 yards/meter of module and one at tufting band to form, as illustrated in the U.S. Patent application that awaits the reply at the same time, be entitled as " method and apparatus of making tufting band carpet ", mention for reference here.
In the tufting band formed module, veil was wound onto on four strands on the square axle and passes through under two ultrasonic transmitters; Once two strands are bonded on the yarn bundle with the single ultrasonic transmitter of two angular contact of axle.The yarn bundle is being cut open between the strand and is still staying on the axle, and four tufting bands of Xing Chenging are led banded a formation on the module like this, and this module contains the substrate base layer that a circle is driven by a plurality of rollers.Article four, the tufting band is guided under the ultrasonic transmitter that is located on one of them roller, at that time transmitter have four forks to contact with each bar tufting band in case with a bond vitrified of four tufting bands to substrate.And then one second transmitter provides additional adhesion energy behind first transmitter.These four tufting lines along the bonding roller move in case with tufting band spirality be wound on the substrate, form three feet wide 12 feet long carpet sample.This carpet sample circle is cut from roller, the sample of test usefulness then cuts from this carpet sample.
Because nylon 6,6 veils are solution dyed, and do not adopt latex in sub-assembly, carpet is not heated when combination, does not therefore have bulk.In order to make carpet bulk, can adopt bulk process separately, as mention in front, simultaneously await the reply and the U.S. Patent application of entrusting, be entitled as " method of bulk tufting band carpet " in illustrated.In this process, veil is being heated by a thermal air current that flows fast on one tenter and is cooling off before unclamping from the tenter pin.
