Abstract
Be fit to wovenly, the flat filament that particularly is made into the elementary carpet lining of tufting carpet square and automobile-use carpet is made up of polyester/vistanex compound and is made by the film that this compound squeezes out through cutting and stretching.
Description
The present invention relates to be used for woven flat filament and with the carpet of this flat filament woven cloths, this flat filament comprises the resin compound that a kind of component is polyester and acrylic polymers.The invention still further relates to the method that is used to make the resin compound of flat filament and makes this flat filament.
The manufacturing of tufted blanket generally comprises tufting on a base fabric, with the base fabric behind tufting washing, dyeing, dry, carry out refine then.
Tufting normally yarn with reciprocating pin band and is passed base fabric, forms pile or yarn circle.The lopping device (Looper) or the hook of pin timing working are located as follows relatively, make when pin is in pole location after passing base fabric in its stroke, the lopping device be in pinprick directly over, the lopping device is immediately won yarn from pin when pin arrives this, and pin is worn back from base fabric and just formed yarn circle or tufting.In typical method, because base fabric moves forward by acupuncture apparatus, the yarn circle leaves the lopping device, and above-mentioned action repeats.If desired, the yarn circle can be severed, for example in the tufting process, be used in combination lopping device and cutter to form clipping.Perhaps do not sever the yarn circle, make it keep the looped pile shape.
Typical flocked base cloth is natural or synthetic fiber or yarn by one or more, for example the fabric or the bondedfibre fabric that constitute of jute, polypropylene, polyethylene, polyamide-based, polyesters and artificial silk.The film of synthetic materials such as polypropylene, polyethylene and ethylene-propylene copolymer also can be used for forming base fabric.
The yarn that is inserted in the tufting process bunch is fixed because of the backtwisting of yarn suede and the contraction of base fabric.In the refine process, the back side of base fabric or stitching surface are coated with usually with adhesive, as latex, emulsion or a kind of hot-melt adhesive of natural or synthetic rubber or resin, to strengthen locking or the set of pile on base fabric.Use this adhesive can also improve the shape stability of tufted blanket, produce the more durable blanket that has improved non-skid property (Skid and slip resistance).Usually, for further increasing its stability, in the refine process, will be added with second bottom on the tufted blanket base fabric, for example one deck is by polypropylene, polyethylene or ethylene-propylene copolymer or the thermoplastic film or fabric or the bondedfibre fabric that constitute such as natural fabrics such as jutes.In the refine process, used adhesive links together base fabric and above-mentioned second bottom.
The carpet lining that is made into by polypropylene filament is widely known by the people, and in commercial extensive use.One example of this base fabric, announce on November 19th, 1963, by the base fabric of pointing out to be used for tufted blanket among the U.S. Pat 3110905 disclosed embodiment is flat, the polyacrylic thermoplastic resin that contains of square-section is made into, the manufacturing of this long filament and use this long filament maker weavening carpet base fabric in the U.S. Pat of announcing on March 31st, 1970 of authorizing people such as port 3503106, to be announced, wherein thermoplastic resin forms film shape coiled material through extruding, make the film orientation by stretching, the film of orientation is cut into flat filament or banded long filament, and folding flat filament feeds loom with flat filament then with folding flat filament pressure and weaves.The long filament of this flat right-angle cross-section often is called flat filament or ribbon-like filament.
At some specific use, it is found that the base fabric of polypropylene flat-filament braiding has some limitation.In car carpeting, the application of woven polypropylene base fabric is limited, usually is to carry out under the temperature that is higher than the polypropylene fusing point because carpet veneer is molded into the automobile inner surface, even be not higher than fusing point, its temperature also usually is so that polypropylene yarn stretches, and damages its dimensional stability.Owing to similar reason, the woven polypropylene base fabric is not suitable for carpet square.Will use hot-melt adhesive when carpet square is attached to the surface, for making this adhesive activation, is heated very high temperature usually, under this temperature, yarn elongation in the base fabric has destroyed dimensional stability.
More known can be used for the automobile carpet veneer with the woven base fabric of other material, carpet square and other need temperature is brought up on the polypropylene fusing point in manufacture process, or so that the blanket structure of polypropylene yarn elongation.Yet materials with high melting point produces other difficulty.Someone advises the woven polyester base fabric is used for automobile carpet veneer and carpet square.Polyester yarn is more high temperature resistant than polypropylene yarn, does not lose dimensional stability basically, yet, the easily broken and wearing and tearing easily of polyester belt yarn, so be unsuitable for the manufacturing of tufted carpet, pin and yarn deflection or fracture always causes the blanket poor quality in the tufting process.
On December 3rd, 1986, laid-open U.S. Patents US4556602 disclosed the polypropylene base fabric that is used for blanket or carpet square, and this base fabric has inweaved the reinforcement yarn that is difficult for elongation than polypropylene in broadwise, is preferably nylon, polyester or glass fibre.With respect to the blanket that is made into the polypropylene base fabric, the dimensional stability of this blanket strengthens to some extent, and others the two is identical, lining goes into to strengthen the cost that weft yarn has increased base fabric, and made production process complicated, and this reinforcement base fabric may contain a lot of polypropylene, is enough to cause the difficulty in the high-temperature process.
Also the someone advises with nonwoven polyester blanket base fabric, and in commercial use, this base fabric has overcome the high temperature limitation of polypropylene base fabric.Yet the orientation at random of the fiber in nonwoven web makes on the one hand it not resemble difficulty the woven polyester strip yarn in the tufting process, and it is good to make but that on the other hand its dimensional stability does not resemble the woven (comprise and being made into by polypropylene).
From the above, be desirable to provide long filament and, its dimensional stability, high temperature resistant processing and all be enough to overcome above-mentioned difficulties with the adaptability of conventional acupuncture technology tufting by the carpet lining of its braiding.One object of the present invention will provide a kind of improved flat filament that is used to make the knitting blanket base fabric of tufted blanket (comprising carpet square and automobile carpet veneer) exactly.Further purpose of the present invention provides this carpet lining and contains the blanket structure of this base fabric.Another object of the present invention provides a kind of resin composition of making this improved long filament and method of cutting the film silk by this resin manufacturing of being applicable to.People for being familiar with in this area can find out other purpose of the present invention from following explanation and claim.

Further embodiment, the invention provides a kind of resin compound, this mixture contains and a kind ofly is approximately 0.7 to 10dl/g poly-(ethylene glycol terephthalate) component and is reference with weight of this poly-(ethylene glycol terephthalate) component according to ASTMD-2857 inherent viscosity in O-chlorophenol (in O-Chlorophenol).Be approximately 17 to 43 percentages, be about 2 to 18g/10 minutes, be crystalline propylene polymer component basically according to ASTM D-1238 condition L melt flowing velocity.
In more detail, yarn of the present invention is characterized as, flat basically rectangular cross section, and width and thickness are even substantially longitudinally along yarn.This yarn is made of a kind of poly-(ethylene glycol terephthalate) component basically, also comprise and be crystalline a kind of propylene component on a small quantity substantially, this propylene component helps making long filament to be easy to be penetrated and don't produce too much fracture and staple fibre by tufting needle the long filament performance loss such as toughness and the dimensional stability that do not have poly-(ethylene glycol terephthalate) component to give in system blanket process.
As the heat that shows two discontinuous melting point values is analyzed pointed, it is inconsistent being somebody's turn to do poly-(ethylene glycol terephthalate) and acrylic polymers, and think poly-(ethylene glycol terephthalate) of the acrylic polymers that is mixed with discontinuous phase to mix or the continuous phase form is present in this yarn, acrylic polymers distributes wherein basically equably.
Be used to make the inherent viscosity of poly-(ethylene glycol terephthalate) component of long filament of the present invention, it is moderate being usually used in packing in the resin with liquid container at those.Though contain minor amounts of copolymerized acid or glycol component present suitable inherent viscosity based on the copolyesters of poly-(ethylene glycol terephthalate) or with the mixture of other polyester and yarn property just can be used, but preferentially select the homopolymers of poly-(ethylene glycol terephthalate) for use.Should poly-(ethylene glycol terephthalate) component can prepare with known technology.Generally, by with 1, the reaction of 2 ethylidene glycols makes esterification of terephthalic acids or derivatives thereof or transesterification, new poly-(terephthaldehyde's acetoacetic ester) component and the resin that from the method for being invented, reclaims, for example: the mixture of leftover pieces or the old material that reclaims from poly-(ethylene glycol terephthalate) fluid container (as Sofe drink bottle) also can use, when choosing the quantity of used reclaimed materials or waste and old material, the composition of acrylic polymers in the leftover pieces that must consider to be reclaimed, the inherent viscosity loss in its poly-(ethylene glycol terephthalate) component and old bottle resin in withdrawal.
The suitable inherent viscosity of poly-(ethylene glycol terephthalate) component is, be approximately 0.7-1dl/g according to ASTM D-2857 (in O-chlorophenol) in the O-chlorophenol, the poly-more difficult extrusion process of carrying out of (ethylene glycol terephthalate) resin of higher inherent viscosity, the squeeze film of this resin does not resemble easy processing the squeeze film of low inherent viscosity resin yet, so be difficult to its slitting.Poly-(ethylene glycol terephthalate) that inherent viscosity is lower than about 0.7dl/g is inappropriate, because the long filament of this poly-(ethylene glycol terephthalate) can not provide enough intensity to the blanket base fabric.And the hydrolysis of this resin in processing procedure reduced its molecular weight, strengthened intractability, and final products intensity is lost.If handle by method of the present invention, the inherent viscosity that is used to make poly-(ethylene glycol terephthalate) component of yarn of the present invention can reduce about 0.15dl/g.Best, with the inherent viscosity of poly-(ethylene glycol terephthalate) component of making long filament of the present invention for to be approximately 0.75 to 0.85dl/g according to ASTM D-2857 (in O-chlorophend) in the O-chlorophenol, because this component is used for film of the present invention and extrudes and have desirable melt process performance when making with flat filament, and this component has sufficiently high inherent viscosity, in processing procedure, can bear the number molecular weight loss of strength, so combine the long filament made from the effective dose propylene polymer component by this resin, have desirable long filament performance, comprise tensile strength and extension property.
It is suitable that poly-(ethylene glycol terephthalate can be buied on market.The polyester that for example comprises medium inherent viscosity can be buied trade mark Cleartuf Polyester from The Goodyear Tire and Rubber Company.
The propylene polymer component that is used to make yarn of the present invention is a kind of crystalline substantially Noblen or copolymer with a small amount of (as the about 30mole% of as many as) one or more copolymerization alpha-olefins (as ethene, butene-1,1-amylene).This acrylic polymers is on sale on market; typical preparation method is; under High Temperature High Pressure; use contains the heterogeneous catalyst of a kind of transition metal halide (for example a kind of have carrier or DNAcarrier free titanium chloride composition) and a kind of organo-metallic compound component (for example a kind of alkyl aluminum or chlorination alkyl aluminum); make propylene or propylene and copolymerization monomer polymerization; usually also to use a kind of molecular weight regulator, for example hydrogen.Also normal use electron donor removes to reduce the amorphous state acrylic polymers that is produced in this polymerization process.A kind of propylene polymer component that the present invention preferentially selects for use is one to be crystalline homo-polypropylene basically.
The melt flowing velocity of this propylene polymer component is, according to ASTM D-1238 condition L about 2 to 18g/10minutes, poly-(the ethylene glycol terephthalate component provides temperature when making yarn by the present invention and the melt strength under the condition to this component for used among the present invention, therefore, make and to be easy to squeeze out the film that thickness does not basically evenly have thin point from this resin compound.The propylene polymer component of higher molten state viscosity (being lower than about 2g/10minutes as the melt flow velocity) more is difficult to be diffused into poly-ly (in the ethylene glycol terephthalate component, and to be made squeeze film be coarse nutty structure, is unsuitable for the application among the present invention.Twice when the degraded of propylene polymer component in processing procedure may cause the melt flow velocity to rise to this material original state.The propylene polymer component of low melt viscosity (for example those melt flow velocitys more than the 18g/10minutes) makes this resin compound fuse undercapacity in the film extrusion process, and weakens film, makes it in uneven thickness, and thin point is arranged.
For obtaining the good diffusion in this poly-(ethylene glycol terephthalate) component, and make this mixture be easy to be squeezed into the basic film uniformly of thickness, the propylene polymer component melt flow velocity of preferentially selecting for use should be according to ASTM D-1238 condition (about 3 to 14g/10 minutes, obtain optimum efficiency 10 minutes the time at about 3.5 to 5 grams.
Long filament of the present invention is by the above-described mixture manufacturing that contains poly-(ethylene glycol terephthalate) and propylene polymer component, its ratio is reference for the weight with poly-(ethylene glycol terephthalate) component, the propylene polymer component of about 17 to 43 percentages.If the amount of acrylic polymers is bigger, then can make the flat filament undercapacity in this mixture, mistake is divided into fibrillation, and has been easy to dirt, can not be satisfactory when making this yarn spinning blanket base fabric structure.If propylene polymer component is lower than 17 percentage by weights, then the acupuncture penetrability during yarn tufting then can not satisfy.
In order to obtain the suitable yarn of good processing properties and intensity, the cloth that is made into by it does not have unnecessary fibril in tufting, pin penetrates easily, resin mixture preferably contains the acrylic polymers composition with polyethylene terephthalate composition weight about 20～35% used according to the present invention, is more preferably the acrylic polymers composition and is approximately 25～33% of weight
This resin mixture can also contain multiple additives and the reagent that generally includes in its each resin composition, such as, antioxidant, stabilizing agent, pigment, delustering agent etc.
By being mixed with out of each resin composition compound of the present invention, it is by polyethylene terephthalate, form with aforesaid acrylic polymers composition, wherein acrylic polymers accounts for greatly with polyethylene terephthalate, the melt-mixed material of 17～43% each composition of composition weight, for example in extruder, the degree of scatter ratio that the acrylic polymers composition reaches in compound is done mixed more even, and doing before the molten formulation mixed and can be helped the more uniform material of mixing that melt production is given birth to.
Be fit to woven according to this invention, and the technical process of cutting the flat yarn manufacturing of film that is particularly suited for producing the woven base fabric of carpet comprises, (a) form melt, make to contain and test with ASTM D-2857, in o-chlorphenol inherent viscosity be approximately 0.7-1.0odl/g polyethylene terephthalate and by the about 17-43% of polyethylene terephthalate composition weight 1 from ASTM D-1238 test condition L, the about 2-18g/10 of melt flow minute, essence is that crystalline acrylic polymers directly mixes, mixture is not moisture substantially, (b) molten mixture is expressed to by a film mould and obtains the quenching film that thickness is unanimity substantially on the chill roll, (c) length along the quenching film cuts into many flat filaments, (d) with about 4: 1-5.5: 1 draw ratio stretching flat filament.In order to reduce the shrinkage factor of long filament, reach the suitable bunch level of knitting carpet square and woven carpet lining cloth, the flat filament of stretching preferably will be through heat treatment.
For fear of the hydrolysis of poly terephthalic acid ethylene glycol in technical process and the loss of molecular weight and performance, polyethylene terephthalate and the acrylic polymers composition that uses in the technical process of the present invention mixed the water-free substantially mixture of formation.Describe the influence of polyethylene terephthalate suction and the dry run and the condition of for this reason recommending in " Good year cleartuf polyester Product Manual " by Good yeer Tire and the publication of Rubber company in detail.Said as the there, can be with the former water capacity of polyethylene terephthalate, vacuum in baking temperature and the equipment becomes the index of aridity of rate of air circulation to decide at vacuum drying oven, biconial rotary vacuum dryer, fluidized bed dryer, chamber dryer still is to carry out drying in air circulation drying oven or the dehumidification stove, there regulation, with dew point-28 ℃, air flow rate is at least 1m
3Air dried baking temperature of/g/Kg/nr is 150～180 ℃.
The moisture that is used to make the polyethylene terephthalate of long filament and acrylic polymers mixture by the present invention approximately is 50ppm or still less.Polyethylene terephthalate can be preferably in about 148～177 ℃ of following dryings approximately 3-5 hour under the situation of no acrylic polymers composition, or when under the situation that the acrylic polymers composition is arranged, being preferably in 120～140 ℃ dry about 10～15 hours, no matter but the sort of situation, all to use the cyclic drying air, especially by the moisture 20ppm that reaches of undried acrylic polymers composition of process use amount of the present invention, therefore, work as polyethylene terephthalate, under the situation that does not have the acrylic polymers composition when dry, preferably be dried to below the 50ppm, 30～40ppm according to appointment so just need not separate drying acrylic polymers composition.
After the drying, send in the head of extruder with the polyethylene terephthalate of drying or with the compound of acrylic polymers, although absorb moisture content ingress of air not in fact for fear of the polyethylene terephthalate of easy moisture absorption, drier, such as a drying box, arrange a suitable outlet, direct and extruder charging aperture is communicated with, and just can reach this point.If want acrylic polymers and dry polyethylene terephthalate, separately enter extruder, will adopt to resin so and divide other metering device.
Polyethylene terephthalate and acrylic polymers are fed in the extruder head and lean on screw rod transmission turning effort hybrid process there, are obtaining the molten mass that each resin composition mixes fully to the pipe there.Additive can measure separately or with composition together, if necessary can add respectively.
Can use the universal master screw device that utilizes in polyester or polypropylene extruding in the technical process of the present invention, this device is equipped with and reaches the bigger best former of extruder material flow flux.Optimum has the recirculated cooling water of cooling material part with a kind of polyester-type screw rod, screw rod center, and at the metering section end suitable mixing head is housed, and the example of so a kind of screw rod is exactly long and the closed polyester screw rod of Tai Weisi-standard of 30: 1 of diameter ratio.
In extruder barrel, resin is in helping polyethylene terephthalate and the acrylic polymers composition is not degraded basically, and can also obtain carrying out hybrid process under the condition that each molten component mixes basically.Though first zone temperatures of machine barrel descends, pretty good also can adopt such as about 10-20 ℃ of result, preferably the distribution of barrel zone temperature still is that machine barrel All Ranges temperature all fixes on horizontal distribution figure on about 275 ° of-300 ℃ of temperature.For making the polyester degradation values reach minimum, also to avoid temperature more than 300 ℃.
Squeeze out the molten mass that polyethylene terephthalate and acrylic polymers mix fully by the film die orifice that is joining extruder barrel outlet.This film mould all is familiar with, and it has one and an extruder and a material road of the die orifice stand-off distance of die lip qualification usually.Suitable mouth mould is that a kind of common standard of film extrusion that is used for is at poly-coventry type die head coventry.The most handy relatively narrow die orifice stand-off distance is guaranteed from the melt thickness of the resin mixture of mouth mould outflow film forming unanimous on the whole.The die orifice stand-off distance preferably is approximately 6-20mil.Mouthful mould is heated to that to keep resinous mixture flow out-of-date be molten state.Heating-up temperature preferably approximately is 270 ℃-300 ℃.
The fused film cooling that mouthful mould is squeezed out promptly obtains thickness quenching film unanimous on the whole, because the melt extruded section bar that comes out from die orifice has relatively low melt strength, settles the chill roll of a cooling to contact cooling with squeeze film nearby so be preferably in mouthful mould.In order to make the yarn defect minimum, the gap between die gap distance and the chill roll is preferably half inch or littler, and the fused film quenching that makes chill roll be cooled to be enough to extruding is got off.General chill roll adopts the recirculated cooling water such as about 60-80 ℃ to cool off.
Cut into many flat filaments along the quenching film length,, can use, allow symphysis continue from row's cutting knife by the most convenient such as laser technology though other.Because the stiffness of quenching film, because the use polypropylene screen is cut the band steel knife of doing commonly used, the band that the result downcuts usually edge roughness causes the edge defect that ruptured when flat filament stretched afterwards, so this cutter is bad again.The most handy have the effective hard composite of tungsten carbide, pottery or titanium carbide coating steel knife or a cutter of crust.
In the cutting process, such as by adjusting the pair roller film feeding or from cutting equipment, send to the speed of film, and roller is abutted against the there, hold film gently and can help the quenching film and be cut into flat filament, just can be cut into the quenching film flat filament of required width through regulating the cutter distance.In the long filament of production and weavening carpet base fabric, cut the film web wide region preferably greatly between 60-500mil.
Follow flat filament with the draw ratio longitudinal stretching cutting-out of about 4-5.5, regulate and improve the longitudinal strength and the toughness of flat filament, be heated to and make the softening and flat filament drawn that polymer molecule might be orientated of flat filament finish the extension process on the vitrification point of polyethylene terephthalate.Temperature is preferably in and is beneficial to flat filament and stretches on 75-110 ℃ that does not rupture again.The flat filament that downcuts passes the thermal treatment zone of suitable insulation, and rolling-up roll rotating ratio feed roller rotating speed is fast; And then reach required level of stretch, again from the feed roller to the work beam, just realized drawing process, as thermal region can be heating furnace, with its hot surface or other appropriate format contact flat filament, because the surface often can support soft flat filament, reduce to minimum thereby produce amount of crimp when making under the no support situation heating flat filament, so the best flat filament that contacts with hot surface of stretching.The mean residence time that flat filament contacts with such hot surface preferably is about half second to 2 seconds.
Suddenly reach about 4 at last by a step or multistep: 1-5.5: 1 the specific energy of tension is implemented drawing process, in one-step method, preferably finish 4.5 greatly under 85-100 ℃: 1-5: the drawing process of 1 draw ratio, what obtain having intensity is about the long filament of 25-45% for 3.4-4.5g/ dawn and elongation.For as the yarn of woven carpet base fabric, width has 30-500mil approximately, and it is best that thickness is about the flat filament that 1.5-3.5mil stretches.
Particularly the flat filament that makes that flat filament is preferably heat-treated in the situation of woven fabric that with slit film yarn is a ground of automobile-use bunch weavening carpet and carpet square making has anti-contracility, flat filament is heated under relaxed state on the vitrification point of polyethylene terephthalate and finishes heat treatment, the flat filament that stretched is suitable for walks around 2 or a plurality of hot-rolling, the roller temperature is on the vitrification point of polyethylene terephthalate, but will be under 165 ℃, lose the long filament performance to avoid acrylic polymers to cross soft, also to reduce roller speed simultaneously, so that softening long filament can shrink, shrinking before the heat treatment and reaching 20% is the characteristic of the flat filament that stretched, reach 10% along with slowing down at least by a string roller, heat treatment under about 138-165 ℃, flat filament shrinks can reduce to 1-4%
