Definitions
- the present invention relates generally to hydroentangled (spunlaced) nonwoven fabrics, and more particularly to hydroentangled laminate nonwoven laminate comprising one or more continuous filament webs, fine denier filament webs, and a cellulosic fiber web, which are integrated so that the cellulosic fibers become integrated with the filamentary structure.
- Nonwoven fabrics embodying the present invention exhibit unique performance attributes, such as improved barrier characteristics, excellent strength and absorbency, and is particularly suited for use in hygiene, medical, and industrial applications
- Nonwoven fabrics are used in a wide variety of applications where the engineered qualities of the fabrics can be advantageously employed.
- the use of selected thermoplastic polymers in the construction of the fibrous fabric component, selected treatment of the fibrous component (either while in fibrous form or while in an integrated structure), and selected use of various mechanisms by which the fibrous component is integrated into a useful fabric, are typical variables by which to adjust and alter the performance of the resultant nonwoven fabric.
- Formation of nonwoven fabrics by hydroentanglement is particularly advantageous in that the fibers or filaments from which the fabric is formed can be efficiently integrated and oriented as may be desired for a specific application.
- Blends of different types of fibers can be readily combined by hydroentanglement so that resultant fabrics exhibiting selected physical properties can be fabricated.
- Continuous filament fabrics are relatively known for being highly porous, and ordinarily require an additional component in order to impart a barrier performance.
- barrier performance has been enhanced by the use of a barrier "melt-blown" layer of very fine filaments, which are drawn and fragmented by a high velocity air stream, and deposited into a self-annealing mass.
- a melt-blown layer exhibits very low porosity, enhancing the barrier properties of laminate fabrics formed with spunbond and melt-blown layers.
- nonwoven fabrics formed from blends of continuous filaments and cellulosic fibers have been known, with such fabrics desirably exhibiting physical properties which are characteristic of the constituent synthetic and cellulosic fibers.
- synthetic fibers can be formed into a fabric so that the characteristics such as good abrasion resistance and tensile strength can be provided in the resultant fabric.
- the use of cellulosic fibers provides such fabrics with desired absorbency and softness.
- U.S. Patent No. 5,459,912 to Oathout discloses patterned, spunlaced fabrics formed from synthetic fibers and wood pulp which are stated as exhibiting good absorbency, and low particle counts.
- the fabrics are thus suited for use where these characteristics are desirable, such as for use as wipes in clean rooms, wipes for food service, and like applications.
- this patent contemplates integration of wood pulp fibers and synthetic fibers in a dry state, with subsequent hydroentanglement by treatment on one side only (prior to aperturing). It is believed that this results in significant loss of the wood pulp fibrous material through the loosely bonded synthetic fibers, thus detracting from the efficiency of the manufacturing process.
- the juxtaposition of continuous filament webs and pulp fibers, with subsequent hydroentanglement has shown significant loss of the wood pulp fibrous material through the filaments due to high level of porosity within the continuous filament web.
- the present invention is directed to a method of making such a laminate nonwoven fabric which facilitates efficient fabric formation by abating loss of cellulosic fibers to the filtrate water during integration by hydroentanglement.
- the present invention is directed to a nonwoven composite fabric comprising one or more layers of discontinuous filaments or napo-fiber filaments positioned between at least one continuous filament web and one cellulosic fiber web that are subsequently hydroentangled, wherein the discontinuous filaments or nano-fiber filaments provide a barrier to prevent the loss of the cellulosic fibrous material through the highly porous continuous filament web.
- the discontinuous filament or nano-fiber layer is lightweight, less than 2 grams per square meter.
- the discontinuous filaments or nano-fiber filaments may be directly extruded onto the continuous filament web or alternately, unwound and positioned atop the continuous filament web.
- the thermoplastic polymers of the continuous filament and discontinuous filament layer or layers are chosen from the group consisting of polyolefins, polyamides, and polyesters, wherein the polyolefins are chosen from the group consisting of polypropylene, polyethylene, and combinations thereof. It is ; within the purview of the present invention that the continuous filament spunbond layer or layers may comprise either the same or different thermoplastic polymers. Further, the continuous filaments of the spunbond layer or layers may comprise homogeneous, bi-component, and/or multi-component profiles and the blends thereof.
- the cellulosic fibrous material of the present fabric is introduced by juxtaposing the cellulosic fibrous web atop the discontinuous filament layer or nano-fiber layer.
- the layered webs are then hydroentangled, and subsequently dried to form the present composite nonwoven fabric.
- the incorporation of a discontinuous filament or nano-fiber layer has been found to desirably minimize loss of the cellulosic material as the various layers are integrated by hydroentanglement.
- FIGURE 1 is a diagrammatic illustration of a process embodying the principles of the present invention.
- the present invention is susceptible of embodiment in various forms, there will hereinafter be described, presently preferred embodiments, with the understanding that the present disclosure is to be considered as 1 an exemplification of the invention, and is not intended to limit the invention to the specific embodiments disclosed herein.
- he present invention is directed to a;nonwoven composite fabric comprising a combination of desirable physical properties.
- the hydroentangled continuous filament layer, discontinuous filament or nano-fiber layer, and cellulosic layer provide a soft and absorbent fabric suitable for various hygiene, medical, and industrial end-use applications, such as wipes and protective cover materials.
- a process for the formation of spunbond involves supplying a molten polymer, which is then extruded under pressure through a large number of orifices in a plate known as a spinneret or die.
- the resulting continuous,filaments are quenched and drawn by any of a number of methods, such as slot draw systems, attenuator guns, or Godet rolls.
- the continuous filaments are collected as a loose web upon a moving foraminous surface, such as a wire mesh conveyor belt.
- a moving foraminous surface such as a wire mesh conveyor belt.
- the subsequent webs is collected upon the uppermost surface of the previously formed web.
- the web is then at least temporarily consolidated, usually by means involving heat and pressure, such as by thermal point bonding.
- thermal point bonding Using this bonding means, the web or layers of webs are passed between two hot metal rolls, one of which has an embossed pattern to impart and achieve the desired degree of point bonding, usually on the order of 10 to 40 percent of the overall surface area being so bonded.
- a process related to the formation of spunbond is the meltblown process, which involves the formation of discontinuous filaments.
- a molten polymer is extruded under pressure through orifices in a spinneret or die. High velocity air impinges upon and entrains the filaments as they exit the die. The energy of this step is such that the formed filaments are greatly reduced in diameter and are fractured so that microfibers of finite length are produced. This differs from the spunbond process whereby the continuity of the filaments is preserved.
- the process to form either a single layer or a multiple-layer fabric is continuous, that is, the process steps are uninterrupted from extrusion of the filaments to form the first layer until the bonded web is wound into a roll.
- meltblown process as well as the cross-sectional profile of the spunbond filament or meltblown microfiber, is not a critical limitation to the practice of the present invention.
- a nano-fiber of finite or infinite length may also be utilized in the present invention, wherein the average fiber diameter of the nano-fiber is in the range of less than or equal to 1000 nanometers, and preferably less than or equal to 500 nanometers. Formation of fabrics from nano-fibers, particularly when ; a light basis weight nano-fiber barrier layer is preferred, is either coated or "dusted" onto a substrate layer.
- the present invention may utilize a nano-fiber layer of less than about 2igrams per square. meter.
- a meltblown layer or nano-fiber layer 4 is directly extruded onto, or unwound and positioned adjacent a spunbond layer 2.
- a cellulosic fiber web 6 is juxtaposed with the meltblown layer or nano-fiber layer 4 for formation of the present composite nonwoven fabric.
- the cellulosic fibers are provided in the form of wood pulp fibers introduced in the form of a wetlaid web, commonly referred to as "tissue 1 '.
- the juxtaposed layers are subjected to hydroentanglement under the influence of high pressure liquid streams generated by suitable manifolds 14 positioned above an entangling belt 12.
- the high pressure liquid streams from the manifolds 14 are directed against a first expansive surface of the juxtaposed webs.
- the layers are directed about another entangling device, such as drum 18, with high pressure liquid streams from manifolds 22 directed against the opposite expansive surface of the webs.
- the now integrated webs can be transferred over a dewatering slot, then dried at 24 and wound for storage and shipment.
- the entangled nonwoven composite may include additional fabric layers, as well as film layers.
- Such film layers may include one or more breathable, apertured, imaged films.
- the composite fabric may be imparted with a three- dimensional image.
- the entangling apparatus may further include an imaging foraminous surface, such as a three-dimensional imaging drum comprising a three-dimensional image transfer device for effecting imaging of the now-entangled laminate.
- imaging foraminous surface such as a three-dimensional imaging drum comprising a three-dimensional image transfer device for effecting imaging of the now-entangled laminate.
- the image transfer device includes a moveable imaging surface which moves relative to a plurality of entangling manifolds which act in cooperation with three-dimensional elements defined by the imaging surface of the image transfer device to affect additional imaging and patterning of the fabric being formed.
- a fabric formed in accordance with the present invention need not be subjected to hydroentangling treatment by direction of hydraulic water jets against both expansive surfaces of the fabric as it is formed. Additionally, it will be recognized that the illustrated nip rolls can be utilized to improve fabric density, and reduce the moisture content of the web prior to drying.
- the composite nonwoven fabric of the present invention may be treated with one or more mechanical or chemical post treatments.
- the resultant fabric may be mechanically compacted and/or additives imparted. to achieve a specific performance within the fabric.
- additives may include pigments, thermochromics, fragrances, emollients, natural herbs and botanicals, UV chemistries, antimicrobials, and the combinations thereof, as well as various other performance or aesthetically modifying additives.
- the composite of the present invention is suitable for various hygiene, medical, and industrial end-uses, whereby the composite is especially suitable for wipes.
