Description

[0001]2067481.0001861 BARRIER FABRICS WITH IMPROVED REPELLENCY CROSS-REFERENCE TO RELATED APPLICATIONS This application claims the benefit of U.S. Provisional Application No.63 / 661,643, filed on June 19, 2024, which is hereby incorporated by reference in its entirety. TECHNICAL FIELD Embodiments of the presently-disclosed invention relate generaly to barier fabrics comprising at least a first nonwoven layer comprising a plurality of first fibers defined by a first polymeric composition. The first polymeric composition includes (i) a first polymer component, and (i) a first additive component comprising at least one non-fluorinated low- surface tension (NFLST) additives dispersed throughout the first polymeric composition. The NFLST additive(s) may be incorporated into the plurality of first fibers by use of a masterbatch including the NFLST additive(s). A variety of articles including such barrier fabrics are also provided. BACKGROUND Alcohol repelent fabrics are frequently used in surgical drapes and gowns. These fabrics often consist of barier fabrics treated with fluoro-chemicals to enhance resistance to penetration by isopropyl alcohol. This has needed in order to meet the industry standards and more precisely to meet the alcohol repelency test. The global regulatory trending desire is to find an approach to eliminate the polyfluorinated (PFC’s) treatments. The byproducts generated in the production of the Fluorine Chemical (FC)’s (e.g., perfluorooctanic acid (PFOA) and perfluooctanesulfonic acid (PFOS), for example, are persistent in the environment and have adverse health efects. In fact, the 2015 Global Suppliers Stewardship phased out of C8 FC and moved to C6 FC to further reduce PFOA and PFOS. Curently, the European Chemicals Agency (ECHA) is in the process of evaluating product lines that use PFC’s. Known Fluoro related chemicals having the lowest critical surface tensions are around 17 mJ / m2 (equivalent to dynes / cm ). In this regard, a fluoro chemical coated surface has alcohol repelency values of up to 80% ~ 90% IPA and prevents blood penetration (Synthetic 2067481.0001861 Blood used in ASTM F1670M with Surface Tension: 35-45 dynes / cm). The reduced surface tension imparted by the fluoro chemical is believed to be the mechanism by which the fluoro- chemical coated surfaces exhibit desirable barier properties to alcohol and blood Therefore, there at least remains a need in the art for a non-fluorine barier approaches, such as via an internal or melt additive, to achieve low surface tension surfaces for fibers and their use in the formation of barrier fabrics that may provide similar or improved barier repelency performance with respect to the penetration of low surface tension fluids (e.g., alcohols and blood). SUMMARY OF INVENTION One or more embodiments of the invention may address one or more of the aforementioned problems. Certain embodiments according to the invention provide a barier fabric that includes at least a first nonwoven layer comprising a plurality of first fibers defined by a first polymeric composition.

In another aspect, the present invention provides a method of forming a barier fabric, such as those described and disclosed herein, in which the method comprises: (i) forming a first polymer melt comprising a first polymeric composition including (a) a first polymer component, and (b) a first additive component, wherein the first additive component includes 2067481.0001861 at least one non-fluorinated low-surface tension (NFLST) additives dispersed throughout the first polymeric composition; (i) melt spinning the first polymer melt to provide a first plurality of fibers; and (ii) consolidating the first plurality of fibers to provide the barier fabric. DETAILED DESCRIPTION The invention now wil be described more fuly hereinafter with reference to the accompanying drawings, in which some, but not al embodiments of the invention are shown. Indeed, this invention may be embodied in many diferent forms and should not be construed as limited to the embodiments set forth herein; rather, these embodiments are provided so that this disclosure wil satisfy applicable legal requirements. As used in the specification, and in the appended claims, the singular forms “a”, “an”, “the”, include plural referents unless the context clearly dictates otherwise. The presently-disclosed invention relates generaly to the use of lower surface tension chemicals in the polymer melt forming a variety of nonwoven materials, in which the low surface tension chemicals are dispersed throughout the body of the individual fibers forming one or more individual nonwoven layers of the barier fabric. The lower surface tension chemicals, such as non-fluorinated low-surface tension (NFLST) additives disclosed and described herein, are devoid of fluorine atoms, which may desirably replace the traditional reliance on fluoro-chemicals while achieving similar or improved barrier repelency performance (e.g., prevent the penetration of low surface tension fluids through the fabric). In accordance with certain embodiments of the invention, for example, the fabrics including the NFLST additive(s) exhibit performance comparable to or beter than C6 fluorine chemical treated materials with respect to preventing lower surface tension fluid penetration and also passing the blood drop test with synthetic blood in accordance with ASTM F1670M (e.g., 15 minutes of droplet exposure without blood penetration). By way of example only, polypropylene may have a surface tension of 30.5 mJ / m2 and polyethylene may have a surface tension of 31.6 mJ / m2. By incorporating the NFLST additive(s) within the body of at least some of the fibers forming the barrier fabric, a reduction of the surface tension of the barier fabric may be achieved due to the NFLST additive(s), which may render the barier fabric resistant to low surface tension fluid penetration. For example, the inclusion the NFLST additives may reduce the surface tension of polypropylene and / or polyethylene by at 2067481.0001861 least about 10%, such as at least about any of the folowing: 10, 15, 20, 25, 30, and 35%, and / or at most about any of the folowing: 75, 70, 65, 60, 55, 50, 45, 40, and 35%. In accordance with certain embodiments of the invention, the barier fabric may be made by any method known, such as those described and disclosed herein. Moreover, the barier fabric may be made from a broad choice of polymeric materials, such as polyolefins (e.g., polypropylene, polyethylene, copolymers thereof, etc.), polyesters, polyamides, natural fibers (e.g., coton, etc.), and celulosic fibers (e.g., rayon, wood fibers, etc.). In accordance with certain embodiments of the invention, for example, the barrier fabric comprises a nonwoven material comprising a polyolefin thermoplastic polymer.

The terms “fabric” and “nonwoven fabric”, as used herein, may comprise a web of fibers in which a plurality of the fibers are mechanicaly entangled or interconnected, fused together, and / or chemicaly bonded together. For example, a nonwoven web of individualy laid fibers may be subjected to a bonding or consolidation process to bond at least a portion of the individualy fibers together to form a coherent (e.g., united) web of interconnected fibers. The term “consolidated” and “consolidation”, as used herein, may comprise the bringing together of at least a portion of the fibers of a nonwoven web into closer proximity or atachment there-between (e.g., thermaly fused together, chemicaly bonded together, and / or mechanicaly entangled together) to form a bonding site, or bonding sites, which function to increase the resistance to external forces (e.g., abrasion and tensile forces), as compared to the unconsolidated web. The bonding site or bonding sites, for example, may comprise a discrete or localized region of the web material that has been softened or melted and optionaly subsequently or simultaneously compressed to form a discrete or localized deformation in the web material. Furthermore, the term “consolidated” may comprise an entire nonwoven web that has been processed such that at least a portion of the fibers are 2067481.0001861 brought into closer proximity or atachment there-between (e.g., thermaly fused together, chemicaly bonded together, and / or mechanicaly entangled together), such as by thermal bonding or mechanical entanglement (e.g., hydroentanglement) as merely a few examples. Furthermore, the term “consolidated” and “consolidation” may comprise the bonding by means of a through-air-bonding operation. The term “through-air bonded” and “though-air- bonding”, as used herein, may comprise a nonwoven web consolidated by a bonding process in which hot air is used to fuse the fibers at the surface of the web and optionaly internaly within the web. By way of example only, hot air can either be blown through the web in a conveyorized oven or sucked through the web as it passes over a porous drum as a vacuum is developed. The temperature of and the rate of hot air are parameters that may determine the level or the extent of bonding in nonwoven web. In accordance with certain embodiments of the invention, the temperature of the hot air may be high enough to melt, induce flowing, and / or fuse the a plurality of fibers having a lower melting point temperature or onset of lower melting point temperature (e.g., amorphous fibers) to a plurality of fibers having a higher melting point temperature or onset of lower melting point temperature (e.g., semi- crystaline or crystaline fibers). Such a web may be considered a “consolidated nonwoven”, “nonwoven fabric” or simply as a “fabric” according to certain embodiments of the invention. The term "layer", as used herein, may comprise a generaly recognizable combination of similar material types and / or functions existing in the X-Y plane. The term “spunbond”, as used herein, may comprise fibers which are formed by extruding molten thermoplastic material as filaments from a plurality of fine, usualy circular, capilaries of a spinneret with the diameter of the extruded filaments then being rapidly reduced. According to an embodiment of the invention, spunbond fibers are generaly not tacky when they are deposited onto a colecting surface and may be generaly continuous as disclosed and described herein. It is noted that the spunbond used in certain composites of the invention may include a nonwoven described in the literature as SPINLACE®. As used herein, the term “continuous fibers” refers to fibers which are not cut from their original length prior to being formed into a nonwoven web or nonwoven fabric. Continuous fibers may have average lengths ranging from greater than about 15 centimeters to more than one meter, and up to the length of the web or fabric being formed. For example, a continuous fiber, as used herein, may comprise a fiber in which the length of the fiber is at least 1,000 times larger than the average diameter of the fiber, such as the length of the fiber being at least about 5,000, 10,000, 50,000, or 100,000 times larger than the average diameter of the fiber. 2067481.0001861 The term “meltblown”, as used herein, may comprise fibers formed by extruding a molten thermoplastic material through a plurality of fine die capilaries as molten threads or filaments into converging high velocity, usualy hot, gas (e.g. air) streams which atenuate the filaments of molten thermoplastic material to reduce their diameter, which may be to microfiber diameter, according to certain embodiments of the invention. According to an embodiment of the invention, the die capilaries may be circular. Thereafter, the meltblown fibers are caried by the high velocity gas stream and are deposited on a colecting surface to form a web of randomly disbursed meltblown fibers. Meltblown fibers may comprise microfibers which may be continuous or discontinuous and are generaly tacky when deposited onto a colecting surface. Meltblown fibers, however, are shorter in length than those of spunbond fibers. The term “melt fibrilation”, as used herein, may comprise a general class of making fibers defined in that one or more polymers are molten and may be extruded into many possible configurations (e.g. co-extrusion, homogeneous or bicomponent films or filaments) and then fibrilated or fiberized into a plurality of individual filaments for the formation of melt-fibrilated fibers. Non limiting examples of melt-fibrilation methods may include melt blowing, melt fiber bursting, and melt film fibrilation. The term “melt-film fibrilation”, as used herein, may comprise a method in which a melt film is produced from a melt and then a fluid is used to form fibers (e.g., melt-film fibrilated fibers) from the melt film. Examples include U.S. Pat. Nos.6,315,806, 5,183,670, 4,536,361, 6,382,526, 6,520,425, and 6,695,992, in which the contents of each are incorporated by reference herein to the extent that such disclosures are consistent with the present disclosure.

The term "fluorochemical", as used herein, may comprise any of various chemical compounds containing fluorine, particularly organic compounds (e.g., fluorocarbons such as perfluoroalkanes) in which fluorine has replaced a large proportion of the hydrogen atached to the carbons. Fluorochemicals may exhibit low surface tension and low viscosity and are extremely stable due to the strength of the carbon-fluorine bond. Fluorochemicals are not miscible with most organic solvents. The term “dry basis", as used herein may comprise the calculation or measurement of a weight percentage in which the presence of water and / or other solvents (e.g., alcohols) are ignored or excluded for purposes of the calculation or measurement. Weight percentages may 2067481.0001861 frequently be measured on a dry basis to remove the effects of evaporation and / or condensation which may happen naturaly throughout the useful life of a composition or article. The term “celulosic fiber”, as used herein, may comprise fibers derived from hardwood trees, softwood trees, or a combination of hardwood and softwood trees prepared for use in, for example, a papermaking furnish and / or fluf pulp furnish by any known suitable digestion, refining, and bleaching operations. The celulosic fibers may comprise recycled fibers and / or virgin fibers. Recycled fibers differ from virgin fibers in that the fibers have gone through the drying process at least once. In certain embodiments, at least a portion of the celulosic fibers may be provided from non-woody herbaceous plants including, but not limited to, kenaf, coton, hemp, jute, flax, sisal, or abaca.

The first polymeric composition includes (i) a first polymer component, and (i) a first additive component comprising at least one non- fluorinated low-surface tension (NFLST) additives dispersed throughout the first polymeric composition. In this regard the NFLST additive(s) may include a single such additive or a 2067481.0001861 combination of several diferent types of such additives, such as those described and disclosed herein. In accordance with certain embodiments of the invention a “polymer component” (e.g., a first polymer component, second polymer component, third polymer components, etc.) as used herein by comprise a polymer or polymer blend that forms a matrix component of the fiber(s) and the “additive component” as used herein may be other components, which may be devoid of polymers or include polymers diferent than those used to form the matrix component, dispersed throughout the matrix component / polymer component. In accordance with certain embodiments of the invention, the NFLST additive(s) may include one or more waxes, such as a parafin wax, a glycerol tristearate, a beeswax, a cuticular wax, or any combination thereof. Persons having ordinary skil in the art understand that many waxes, particularly naturaly occuring waxes, include a combination of individual components. For example, naturaly occuring beeswax includes palmitate, palmitoleate, and oleate esters of long-chain (e.g.30-32 carbons) aliphatic alcohols, with each individual component being a “component thereof” in relation to beeswax. For ease of reference, the term “wax or component thereof” may be colectively refered to as “wax” throughout the remaining description. In accordance with certain embodiments of the invention, the one or more waxes may include from about 30 to about 80 carbon atoms, such as at least about any of the folowing: 30, 32, 35, 38, 40, 42, 45, 48, and 50 carbon atoms, and / or at most about any of the folowing: 80, 75, 70, 65, 60, 58, 57, 56, 55, 52, and 50 carbon atoms. Additionaly or alternatively, the one or more waxes may have an acid value of from 0.1 mg to 220 mg, KOH / g as measured in accordance with the Enterprise Standard Test, such as at least about any of the folowing: 0.1, 0.2, 0.3, 0.5, 0.8, 1, 1.5, 2, 2.5, 3, 5, 8, 10, 15, 20, 30, 40, 50, 60, 80, and 100 mg, KOH / g as measured in accordance with the Enterprise Standard Test, and / or at most about any of the folowing: 220, 200, 180, 160, 150, 140, 120, and 100 mg, KOH / g as measured in accordance with the Enterprise Standard Test.

Cuticular wax, for example, plays a major role in the growth and storage of plant fruits. The cuticular wax coating, which covers the outermost layer of a fruit's epidermal 2067481.0001861 cels, is insoluble in water. Cuticular wax is mainly composed of very long-chain faty acids (VLCFAs); their derivatives, including esters, primary alcohols, secondary alcohols, aldehydes, and ketones; and triterpenoids. This complex mixture of lipids is probably biosynthesized in the epidermal cels of most plants and exuded onto the surface. Cuticular wax not only makes the fruit less susceptible to microbial infection but also reduces mechanical damage to the fruit, thereby maintaining the fruit’s commodity value. To date, research has mostly focused on the changes, function, and regulation of fruit wax before harvest, while ignoring the changes and functions of wax in fruit storage. Beeswax includes hydrocarbons (12%–16%) with a predominant chain length of C27–C33, mainly heptacosane, nonacosane, hentriacontane, pentacosane and tricosane ; free faty acids (12%–14%), with a chain length of C24–C32 ; free faty alcohols (ca.1%) of C28–C35 ; linear wax monoesters and hydroxymonoesters (35%–45%) with chain lengths generaly of C40–C48, derived fundamentaly from palmitic, 15-hydroxypalmitic and oleic acids ; complex wax esters (15%–27%) containing 15-hydroxypalmitic acid or diols, which through their hydroxyl group, are linked to another faty-acid molecule ; exogenous substances that are mainly residues of propolis, polen, smal pieces of floral component factors and polution.

In another aspect, the present invention provides an article comprising a barier fabric, such as those described and disclosed herein. The article may comprise , for example, personal protective equipment (PPE) or personal incontinence products (PIP). By way of example only, the article may be a PPE item such as coverals, leggings, lab coats, aprons, headgear, positive pressure suits, surgical gowns, surgical drapes, pants, jackets, and facemasks. By way of example only, the article may be a PIP item such as feminine hygiene pads, diapers, pul-ups, and adult diapers. The article may also comprise ostomy bags and / or related products, or wound care products (e.g., gauzes or wound dressings). In another aspect, the present invention provides an article comprising (i) a backsheet comprising a barrier fabric, such as those described and disclosed herein; (i) a liquid 2067481.0001861 permeable topsheet; and (ii) an absorbent core located between the backsheet and the liquid permeable topsheet. The article may comprise, for example, a surgical gown, a female hygiene article, an underpad, or a diaper. Ostomy bags and / or related products, and wound care products (e.g., gauzes or wound dressings), in accordance with certain embodiments of the invention, the barier fabric, such as those described and disclosed herein, may exhibit an improved drying rate and / or time as compared to non-treated fabrics having an identical construction (e.g., same polymer system, same basis weight, same fiber types and sizes, etc.) but lacking the NFLST additive(s). In accordance with certain embodiments of the invention, the ability of a nonwoven fabric (e.g., barier fabric), such as those described and disclosed herein having one or more NFLST additives, to dry after bathing or cleaning a user’s skin around the area where, for example, the ostomy bag is in contact with the skin is particularly important. In this regard, ostomy bags may comprise at least an outermost surface at least partialy defined by a barier fabric as described and disclosed herein. For instance, the barrier fabric, such as those described and disclosed herein, forming al or a portion of an ostomy bag adjacent and / or proximate to a user’s skin may have a drying time. For example, ostomy bags, in accordance with certain embodiments of the invention, may include an outermost layer of a nonwoven fabric, such as those described and disclosed herein, and an interior film layer that prevents liquid or fecal mater from passing through the body of the ostomy bag. The nonwoven fabric and the interior film layer (e.g., film layer) may be bonded to each other via a variety of techniques, for example, adhesively bonded, ultrasonicaly bonded, thermaly bonded, or the film layer may be melt extruded directly onto the nonwoven fabric. The film layer may not be particularly limited as long as the film provides adequate liquid and / or gaseous barier properties to prevent undesirable passage of liquids and / or gases from inside the ostomy bag to an external environment. In accordance with certain embodiments of the invention, the nonwoven fabric may simply comprises a spunbond nonwoven fabric (e.g., including from 1 to 10 individual spunbond layers) including at least one NFLST additive therein. Such nonwoven fabrics may have a smaler barier efect (e.g., lower hydrostatic head, alcohol repelency, etc.) compared to nonwoven fabrics having a general spunbond-meltblown-spunbond structure. Alternatively, the nonwoven fabric may comprise a general spunbond-meltblown-spunbond structure, such as those described and disclosed herein, that provide a larger barrier effect (e.g., larger hydrostatic head, alcohol repelency, etc.) compared to a simply spunbond nonwoven fabric. In this regard, the relative “barier effect” of the nonwoven fabric utilized in an ostomy bag 2067481.0001861 (or wound care article) may be varied as desired. For example, nonwoven fabrics having a larger the barier efect (e.g., SMS-type nonwoven fabrics) may prevent a capilary efect between the nonwoven fabric and the film layer while nonwoven fabrics having a smaler barier efect (e.g., spunbond nonwoven fabric) may alow fluid to drain from an interface between the nonwoven fabric and the film layer. In another aspect, the present invention provides a method of forming a barier fabric, such as those described and disclosed herein, in which the method comprises: (i) forming a first polymer melt comprising a first polymeric composition including (a) a first polymer component, and (b) a first additive component, wherein the first additive component includes at least one non-fluorinated low-surface tension (NFLST) additives dispersed throughout the first polymeric composition; (i) meltspinning the first polymer melt to provide a first plurality of fibers; and (ii) consolidating the first plurality of fibers to provide the barier fabric. In accordance with certain embodiments of the invention, the step of forming a first polymer melt comprises adding a master batch including the at least one NFLST additives to the polymer component. The first plurality of fibers, as noted above, may comprise continuous spunbond fiber or meltblown fibers. In this regard, the step of meltspinning the first polymer melt to provide a first plurality of fibers may be a spunbond process or a meltblown process. In accordance with certain embodiments of the invention, the step of meltspinning the first polymer melt to provide a first plurality of fibers is a spunbond process, and the method may further comprise (i) forming a second polymer melt comprising a second polymeric composition including (a) a second polymer component, and (b) a second additive component, wherein the second additive component includes at least one non-fluorinated low-surface tension (NFLST) additives dispersed throughout the second polymeric composition, and (i) meltspinning the second polymer melt via a spunbond process to form a second plurality of continuous spunbond fibers. The method may also comprise (i) forming a third polymer melt comprising a third polymeric composition including (a) a third polymer component, and (b) a third additive component, wherein the third additive component includes at least one non-fluorinated low-surface tension (NFLST) additives dispersed throughout the third polymeric composition, and (i) meltspinning the second polymer melt via a meltblown process to form a plurality of meltblown fibers. In accordance with certain embodiments of the invention, the method may comprise a step of depositing the plurality of meltblown fibers onto the first plurality of continuous spunbond fibers, and depositing the 2067481.0001861 second plurality of continuous spunbond fibers onto the plurality of meltblown fibers. Additionaly, the consolidating step may comprise bonding each of the individual layers present together via a thermal bonding operation and / or an ultrasonic bonding operation. In accordance with certain embodiments of the invention, the thermal bonding operation and / or ultrasonic bonding operation forms a plurality of discrete bond sites defining a bonded area. The bonded area, for example, may comprise from about 8 to about 40%, such as at least about any of the folowing: 8, 10, 12, 15, 18, 20, 22, and 25%, and / or at most about any of the folowing: 40, 35, 30, 28, and 25%. Examples The present disclosure is further ilustrated by the folowing examples, which in no way should be construed as being limiting. That is, the specific features described in the folowing examples are merely ilustrative and not limiting. A. Test Methods Basis weight of the folowing examples was measured according to ASTM test method D3776. The results were provided in units of mass per unit area in g / m2 (gsm). Alcohol repelency of the folowing examples was measured according to test method IST 80.8 Hydrohead of the folowing examples was measured according to standard test method IST 80.8 and ramping up the pressure at a rate of 60 mbar / min. A larger hydrohead value is more desirable for increased the barier performance. Air Permeability is a measure of air flow passing through a sheet under at a stated pressure differential between the surfaces of the sheet and was conducted according to ASTM D 737, Test area 38cm2, Test Pressure @ 125 Pa, and is reported in ml / dm2 / min. A larger air permeability value is indicative of improved comfort for surgical gown and drape applications. Low Surface Tension Strikethrough Time (LSTST) is a test that determines the time it takes for a particular quantity of liquid discharged at a prescribed rate to fuly penetrate a sample of a nonwoven fabric. The method employed herein is a modification to WSP 70.3 (05). The changes were as folows: the test liquid was a 32 mN / m surface tension liquid prepared with Triton-X-100 and distiled water. B. Spunbond Barier / Repelency The lower surface tension fluoro-free additive chemical & masterbatch treated nonwoven fabrics wil have longer surface tension strikethrough time and alcohol repelency, 2067481.0001861 such as around 50% IPA or 70% ~ 80% Ethanol repelency or higher as wel as prevent blood penetration. Polypropylene resin carier was mixed with diferent NFLST additives and varying loadings, in which the mixing temperature was ~ 2200°C for spunbond lines and for fiber spinning and ~ 2600°C for meltblown lines and for fiber spinning. The melt additive (NFLST additives) active loading % was considered at the folowing: 0.5% w / w to 10% w / w , 20% w / w, 30% w / w . The melting points cover from 40°C to 200°C. The wax can be beeswax, fruit or plant wax, but not necessarily limited. In these examples, two diferent types of waxes and one modified siloxane product were studied: Chemical A: Parafin Wax ; Chemical B :Bath Wax; and Chemical C: TEGO 1345 modified siloxane product, which has PDMS polymers with organic groups grafted on to either the chain ends or the main chain in places.
