the explanation of preferred embodiment
Batt of the present invention can by such as forming from spinning the continuous print multicomponent fibre that molten process produces.Under spinning head, extrude fiber and decay subsequently, cool also lay in bringing, to form the batt of fiber.During this process, these fibers can automatic curled.Can described batt be converted to non-textile fabric.
Filament is made up of at least two polymers compositions A and B, wherein described polymers compositions is passed to described spinning head respectively, and in obtained fiber, there is the part of the mainly part of an A polymers compositions and one mainly B polymers compositions, and wherein arrange in the following manner in the described part in the cross section of described fiber: curling with regard to Muller's fibers during the setting process process of fiber.These regions such as can be found in the opposition side of fibre section, and therefore formation is called as arrangement known in the bicomponent fiber of parallel type, or such as therefore a part also can form around Part II the arrangement being called as core-Pi, wherein in order to ensure the curling object of fiber, the cross section that is always arranged in two parts of principal polymeric component A, B is asymmetric.In another arrangement, described fiber can containing three polymer moieties with principal polymeric component A, B, C, such as to be called as " cake of fragmentation " or the spread pattern of " fabric of island-in-sea type " arranges, wherein in order to ensure the curling object of fiber, the cross section that is always arranged in two parts of principal polymeric component A, B is asymmetric.
Do not attempt to be bound by theory, it is believed that and adjust with Muller's fibers curling to the mutual arrangement of the part in fibre section with principal polymeric component, the asymmetric degree of such as described polymers compositions is expressed as already during fiber setting process, the curling result that its appreciable impact is final, can not suppose the asymmetric larger of fiber alignment simply, what cause is curling more obvious.On the contrary, be necessary the character also considering one pack system, wherein can occur the synergy arranged, and the more distant fiber of asymmetric arrangement may promote curling larger than the more obvious fiber of asymmetric arrangement.It will be appreciated by those skilled in the art that in fiber that the optimal arrangement of the part with principal polymeric component can be determined in laboratory test, such as, use little laboratory spinning head.The example of single asymmetric arrangement and the curling example arrangement of Muller's fibers are shown in Figure 1A, are not limited to those examples presented herein.Based on the definition provided above, not that asymmetric or that Muller's fibers are not curling usually arrangement is shown in Figure 1B.
Forming curling fiber by the significant difference (be usually expressed as and utilize so-called one pack system shrinkage) of single polymers compositions character is well-known in the industry.The known fiber produced by this way is named as chemistry and forms fiber.What it will be appreciated by those skilled in the art that the main description of term " component shrinkage " is from liquid to stereomutation solid state transition process, and it is by the impact of the various character of polymer.Such as, for bicomponent fiber, the combination of two kinds of polymer can be used.Such as, a kind of polymer is together with another kind of polymer (polypropylene+polyethylene), copolymer (polypropylene+polypropylene copolymer) or blend (polypropylene+polypropylene blend and polypropylene copolymer).When use two kinds of polymer, be always necessary to consider used material and their mutual miscibilty very carefully.Their degree different from each other are larger, and the possibility that in fiber, two part level of adhesion of principal polymeric component are lower is larger, and the decomposition of fiber may occur.Especially in hygiene applications, even if the fiber hydrolization of not half is all very undesirable, because it can be " bobbles " and therefore occur on the surface of the product by itself on the surface of fabric, End-Customer is regarded as the inferior mark of product quality.Also knownly can use the same polymer with heterogeneity (difference such as in the degree of crystallinity or its elasticity of melt flow index, polydispersity, material), wherein for successfully it is essential these parameters at least one in there is significant difference.
Such as based on the European patent EP 0685579 from Kimberley Clarke (KimberleyClark), when polydispersity, the difference of at least 0.5 is necessary in exactly determined region---one of this file display key component has the polydispersity of <2.5, and second >3; For degree of crystallinity, the key component of a part be unbodied and other part be crystal be necessary, and the difference of melting heat must at least 40J/g; And be applicable to spin the molten melt flow index applied from units to the scope of thousands of g/10min, for elasticity, the combination of elasticity and non-elastic material is necessary.
Theme of the present invention is curling multicomponent fibre, and wherein in part, the main polymer used is very similar each other.Preferred described polymer can be chemically identical, only has not same in physical property, such as polypropylene-Polypropylene compositions.Those skilled in the art are to be understood that, such as polypropylene (polymer be made up of propylene monomer units) has essential characteristic, but in such as polymer, the distribution of the independent succession of unit or the length of polymer chain or different polymer chain can bring change to producing significant physical property to fiber and non-thermoplastic.It will be understood by those skilled in the art that the wide region of commercial polymer type, and be also to be understood that various amount and the availability of single type.Due to the distribution of demand, quotation also concentrates on the polymer in the region of character relative narrowness especially.What use remarkable similar polymer to bring is sizablely also advantageous in that they relatively easily commercially obtain.
Be necessary it is emphasised that, described polymer moieties can use a kind of polymer to be formed, and the blend of various compound maybe can be used to be formed.Known also exist the fiber be made up of the multicomponent fibre based on same polymer in the industry, and described component is only different in the interpolation of admixture.U.S.'s file 6,203,905 such as from Kimberly-Clark (KimberlyClark) describes part nucleating additive being added into bicomponent fiber.
Body of the present invention (principle) can only be made up of principal polymeric component or be made up of the additive of key component and interpolation.
Body of the present invention also can contain the interpolation (such as dyestuff) of additive, but the interpolation not appreciable impact fiber of such additive is curling.Such as, symmetrically described additive can be added to two parts.
As known in the industry, some functional additives directly can induce the chemical reaction in the polymer of melting immediately before weaving, and can be affected their effect (such as from the IRGATECCR76 of BASF) by such as melt temperature.By this way, by the effect of the various melt temperatures of two kinds of polymers compositionss for part, namely box lunch uses the significant difference that also can produce obtained character (such as melt flow index, polydispersity etc.) during the mixture of identical polymer and additive in two parts.Body of the present invention can contain the interpolation of functional additive, but this interpolation not appreciable impact fiber is curling.
As apparent from word before can, known in the industry, the shrinkage as the key component in fruit part is enough different, produces tension force in the curling fiber so caused at spinning head.Produced by the combination of the nuance of at least two of polymer, preferably three parameter based on the curling of fiber of the present invention.
Key variables are latent heat (dHc), and it is the index being necessary the amount obtained from system for the energy that polymers compositions crystallization occurs.Well-known theory is thought, if temperature contrast is enough, key component so in a part first will start sizing, and consequent tension force does not have opposition to still liquid key component in the second portion, thus described fiber can be curling.Always be necessary, between two kinds of polymers compositionss, there is enough difference, otherwise this effect can not occur.
The EP0685579 of known file Kimberly-Clark (KimberlyClark) determines the minimum difference of melting heat, and it approximates greatly the crystallization heat of 40J/g.On the contrary, according to the present invention, when utilizing the surprising remarkable synergy of other difference between key component in part, fiber be crimped onto less difference under occur.Curling (cruling) or curling (crimping) based on fiber of the present invention be by the crystallization heat of polymer (dHc) and at least one, preferably produce more than the combination of the nuance of two parameters.
Single key component is different in crystallization heat (dHc), the difference of its intermediate value at 30J/g to 5J/g, be more preferably at 30J/g to 10J/g, and the scope of preferred 30J/g to 20J/g.Curling for compared with low degree, crystallization heat difference (dHc) can at 24J/g to 5J/g, be more preferably at 24J/g to 10J/g, and the scope of preferred 24J/g to 20J/g.In addition, single key component can be different in melt flow index (MFI) is horizontal, the difference of its intermediate value at about 100g/10min to 5g/10min, be more preferably 80g/10min, the scope of preferred 60g/10min to 10g/10min.
In addition, single key component can be different in the degree of polymolecularity of material, the difference of its intermediate value 1 to 0.3, be more preferably 1 to 0.5, and preferably 1 to 0.75 scope.
In addition, single key component can be different in the flexural modulus of material, the difference of its intermediate value at 300MPa to 50MPa, be more preferably 250MPa to 80MPa, and the scope of preferred 200MPa to 80MPa.
Need not be bound by theory, we suppose that the curling of fiber is caused by the tension force of fiber, when a part crystallization already, and other part keep liquid condition or its crystallization degree lower at this given time point.In the ordinary course of things, during crystallization process, become less to the volume of certain portions, and if remain ductile in these given time other parts, it can not present patience and the fiber crimp of very large level.Seemed to see by foregoing, except latent heat value (dHc) itself, the temperature that crystallization occurs and crystallization rate also can have impact to amount of crimp.Be the fact of the combination of two kinds of remarkable similar polymer about theme of the present invention, they also may have similar crystallization temperature.The example of the homopolymer of various types of commercial polypropylene is shown in table.
Need not be bound by theory, we suppose with the crystallization time difference of the order of a few minutes himself not having remarkable effect power to cause the curling of fiber, but also there is contribution to the amount of crimp caused by above-mentioned difference, namely in latent heat (dHc).
The single key component of part is different in crystallization temperature, and the difference of its intermediate value is at about 5-30 DEG C, preferably 5-25 DEG C, and the scope of preferred 8-25 DEG C.
The single key component of part is different in crystallization rate, the difference of its intermediate value at least 20 seconds, preferably 50 second, preferably 120 seconds, and preferably 150 seconds.
Polymers compositions prepared burden (1) enter independent extrusion system (2), wherein they are melted, are heated to suitable operating temperature and are taken to spinning head (4) respectively, wherein form multicomponent fibre.Those skilled in the art are to be understood that, the spinning process that preparation polymer is used for multicomponent form depends on that the type of skill also comprises concrete steps, and following true: the various additives designeding to be used this object may be added to polymers compositions for such as changing the object of fiber color (dyestuff) or change fibre property (such as hydrophily, hydrophobicity, flame resistance), wherein according to the present invention importantly, the curling of fiber is not affected for these additives of described material, and/or they are scattered in obtained fiber symmetrically.The fiber (5) formed under spinning head (8) is exposed to the air (6,7) of cooling steam and decay, and therefore to be formed on it before fall (8) are upper to collecting pad (10) curling for fiber.Both air (6,7) of cooling and decay all have the temperature of about room temperature, preferably 10-30 DEG C, more preferably 15-25 DEG C.Such as collecting pad (10) can be the moving belt transporting formed fiber batt (11).To in the road process on collecting pad (10), extra heat or mechanical energy is not had to enter to support curling.
By this way, can be arranged in order some spinning warp beams, wherein they can produce curling fiber, or can the different layer of lay (such as simply spin molten fiber---such as spunbond or melt-blown, nanofiber, film etc.).For design of the present invention, advantageously, if the layer of crimped fibre by lay on other layer, make the bad compression that curling fiber does not occur.For other application, it may be favourable for carrying out combination, wherein curling fiber is from first and last spinning warp beam release, obtained material is had by curling fibrous outer surface, and internal layer can have different character (mechanical strength of such as obtained non-thermoplastic fabric).
The layer (12) of reinforcing fibre subsequently, wherein can use known several method (such as heat bonding, hot calendering bonding, needle point method, water acupuncture manipulation etc.).Single Method for bonding has remarkable effect to obtained material character, and those skilled in the art can determine which kind of method is suitable for its material easily.Equally, those skilled in the art it should also be understood that, have selecting of the adhesive bonding method of more high strength or bounding point density, even can cause negates the total bulkiness containing the standard material of the non-thermoplastic fabric based on fiber of the present invention and the fiber containing non-crimping obtained.
