Background

For a variety of reasons, consumers desire fabrics comprising cellulosic fibers. However, while fabrics comprising such fibers have many desirable properties, they also have disadvantages well known in the industry. For example, fabrics comprising cellulosic fibers, particularly regenerated cellulosic fibers, may be associated with poor dimensional stability (including stretching tendency), tendency to wrinkle, poor wicking, long drying times, and poor thermal conductivity, which can result in a feeling of coolness when the fabric is used normally. While cellulose fibers are often blended with other natural and/or synthetic fibers to provide blends that are intended to address some of the aforementioned disadvantages, it has been found that currently available blends of cellulose fibers with other natural and/or synthetic fibers do not adequately address the array of disadvantages associated with cellulose fibers.

Thus, despite advances in textile research, there remains an important need for fabrics comprising cellulosic fibers that can address known shortcomings of fabrics comprising such fibers, such as wicking, drying time, dimensional stability, cooling properties, and poor thermal conductivity, while maintaining consumer desired hand and function. The present disclosure satisfies these needs and others.

Detailed Description

Many modifications and other embodiments of the disclosure set forth herein will come to mind to one skilled in the art to which the disclosed compositions and methods pertain having the benefit of the teachings presented in the foregoing descriptions and the associated drawings. Therefore, it is to be understood that the disclosure is not to be limited to the specific embodiments disclosed and that modifications and other embodiments are intended to be included within the scope of the appended claims. The skilled person will recognise many variations and adaptations of the various aspects described herein. Such modifications and adaptations are intended to be included within the teachings of the present disclosure and are intended to be covered by the claims herein.

Although specific terms are employed herein, they are used in a generic and descriptive sense only and not for purposes of limitation.

As will be apparent to those of skill in the art upon reading this disclosure, each of the individual embodiments described and illustrated herein has discrete components and features that may be readily separated from or combined with the features of any of the other several embodiments without departing from the scope or spirit of the present disclosure.

Any recited method may be performed in the order of events recited, or in any other order that is logically possible. That is, unless explicitly stated otherwise, it is in no way intended that any method or aspect set forth herein be construed as requiring that its steps be performed in a specific order. Thus, to the extent that the method claims are not specifically recited in a claim or in the specification as a particular order of steps, it is in no way intended that an order be implied in any way. This applies to any possible non-explicit basis for interpretation, including logical problems with regard to step arrangement or operational flow, simple implications derived from grammatical organization or punctuation, or the number or type of aspects described in the specification.

All publications mentioned herein are incorporated herein by reference to disclose and describe the methods and/or materials in connection with which the publications are cited. The publications discussed herein are provided solely for their disclosure prior to the filing date of the present application. Nothing herein is to be construed as an admission that the invention is not entitled to antedate such publication by virtue of prior invention. Further, the publication dates provided herein may be different from the actual publication dates, which may require independent confirmation.

Although various aspects of the disclosure may be described and claimed in particular legal categories, such as the system legal category, this is for convenience only and those skilled in the art will understand that each aspect of the disclosure may be described and claimed in any legal category.

It is also to be understood that the terminology used herein is for the purpose of describing particular aspects only and is not intended to be limiting. Unless defined otherwise, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which the disclosed compositions and methods belong. It will be further understood that terms, such as those defined in commonly used dictionaries, should be interpreted as having a meaning that is consistent with their meaning in the context of specification and relevant art and will not be interpreted in an idealized or overly formal sense unless expressly so defined herein.

Before describing various aspects of the present disclosure, the following definitions should be provided and used, unless otherwise specified. Additional terms may be defined elsewhere in this disclosure.

A. Definition of

As used herein, "comprising" is to be interpreted as specifying the presence of the stated features, integers, steps or components as referred to, but does not preclude the presence or addition of one or more features, integers, steps or components, or groups thereof. Moreover, the term "comprising" is intended to include the examples and aspects covered by the terms "consisting essentially of … …" and "consisting of … …". Similarly, the term "consisting essentially of … …" is intended to include the example covered by the term "consisting of … …".

As used herein, the term "prepared from … …" is synonymous with "including". As used herein, the terms "comprises," "comprising," "includes," "including," "has," "having" or "containing" or any other variation thereof, are intended to cover a non-exclusive inclusion. For example, a composition, process, method, article, or apparatus that comprises a list of elements is not necessarily limited to only those elements but may include other elements not expressly listed or inherent to such composition, process, method, article, or apparatus.

The conjunction "consisting of … …" excludes any element, step, or ingredient not specified. If in the claims, such phrase is intended to exclude the claims from including materials other than those listed, other than the impurities normally associated with the listed materials. When the phrase "consisting of … …" appears in the clause of the body of the claims and does not immediately follow the preamble, it only limits the elements specified in the clause; other elements are not excluded from the claims as a whole.

The conjunction "consisting essentially of … …" is used to define a composition, method, or apparatus that includes additional materials, steps, features, components, or elements in addition to the materials, steps, features, components, or elements literally discussed, provided that the additional materials, steps, features, components, or elements do not materially affect the basic and novel characteristics of the claimed invention. The term "consisting essentially of … …" is intermediate between "comprising" and "consisting of … …".

Further, "or" refers to an inclusive "or" rather than an exclusive "or" unless expressly stated otherwise. For example, condition a "or" B "satisfies either of the following conditions: a is true (or present) and B is false (or not present), a is false (or not present) and B is true (or present), and both a and B are true (or present).

As used in the specification and the appended claims, the singular forms "a", "an", and "the" include plural referents unless the context clearly dictates otherwise. Thus, for example, reference to "a polymer," "a yarn," or "a fabric" includes, but is not limited to, two or more such polymers, yarns, or fabrics, and the like. Thus, "a" or "an" should be understood to include one or at least one and the singular forms of an element or component also include the plural unless the number is clearly singular.

It should be noted that ratios, concentrations, amounts, and other numerical data may be expressed herein in a range format. It will be further understood that the endpoints of each of the ranges are significant both in relation to the other endpoint, and independently of the other endpoint. It will also be understood that a plurality of values are disclosed herein, and that each value is also disclosed herein as "about" that particular value, in addition to the value itself. For example, if the value "10" is disclosed, then "about 10" is also disclosed. Ranges can be expressed herein as from "about" one particular value, and/or to "about" another particular value. Similarly, when values are expressed as approximations, by use of the antecedent "about," it will be understood that the particular value forms another aspect. For example, if a value of "about 10" is disclosed, then "10" is also disclosed.

When a range is expressed, another aspect includes from the one particular value and/or to the other particular value. For example, when a stated range includes one or both of the limits, ranges excluding either or both of those included limits are also included in the disclosure, e.g., the phrase "x to y" includes ranges from "x" to "y" as well as ranges greater than "x" and less than "y". This range may also be expressed as an upper limit, such as "about x, y, z, or less," and should be interpreted to also include the specific ranges of "about x," about y, "and" about z, "as well as ranges of" less than x, "less than y, and" less than z. Likewise, the phrase "about x, y, z or greater" should be interpreted to include the particular ranges of "about x", "about y", and "about z" as well as the ranges of "greater than x", "greater than y", and "greater than z". Further, the phrase "about 'x' to 'y'" includes "about 'x' to about 'y'", where

'x' and 'y' are numerical values.

It is to be understood that such a range format is used for convenience and brevity, and thus, should be interpreted in a flexible manner to include not only the numerical values explicitly recited as the limits of the range, but also to include all the individual numerical values or sub-ranges encompassed within that range as if each numerical value and sub-range is explicitly recited. For purposes of this specification, a numerical range of "about 0.1% to about 5%" should be interpreted to include not only the explicitly recited values of about 0.1% to about 5%, but also include individual values (e.g., about 1%, about 2%, about 3%, and about 4%) and sub-ranges (e.g., about 0.5% to about 1.1%, about 5% to about 2.4%, about 0.5% to about 3.2%, and about 0.5% to about 4.4%, as well as other possible sub-ranges) within the indicated range. For further explanation, when a range of "1 to 5" is recited, the recited range should be interpreted to include the ranges "1 to 4", "1 to 3", "1 to 2 and 4 to 5", "1 to 3 and 5", and the like.

As used herein, the terms "about," "approximately," "equal to or about," and "substantially" mean that the amount or value in question may be an exact value or a value that provides an equivalent result or effect to that recited in the claims and taught herein. That is, it is to be understood that quantities, sizes, formulations, parameters and other quantities and characteristics are not and need not be exact, but may be approximate and/or larger or smaller, as desired, reflecting tolerances, conversion factors, rounding off, measurement error and the like, and other factors known to those of skill in the art to achieve an equivalent result or effect. In some cases, it is not reasonable to determine the value that provides an equivalent result or effect. In this case, unless otherwise specified or implied, it is generally understood that "about" and "equal to or about" as used herein mean nominal values indicating a ± 10% variation. Generally, an amount, dimension, formula, parameter, or other quantity or characteristic is "about," "approximately" or "equal to or about," whether or not specifically stated to be so. It is to be understood that where "about", "approximately" or "equal to or about" is used before a quantitative value, the parameter also includes the specific quantitative value itself, unless specifically stated otherwise.

The terms "decrease", "reduction" or "inhibition" are all used herein to generally mean a decrease in a statistically significant amount. However, for the avoidance of doubt, "reduce", "decrease" or "inhibit" means a decrease of at least 10% compared to a reference level, such as a decrease of at least about 20%, or at least about 30%, or at least about 40%, or at least about 50%, or at least about 60%, or at least about 70%, or at least about 80%, or at least about 90%, or up to and including 100% decrease (e.g., a level not present compared to a reference sample), or any decrease of 10% to 100% compared to a reference level.

The terms "increase", "augmentation" or "enhancement" or "activation" are all used herein to generally mean an increase in a statistically significant amount; for the avoidance of any doubt, the terms "increase", "increase" or "enhancement" or "activation" refer to an increase of at least 10% as compared to a reference level, for example an increase of at least about 20%, or at least about 30%, or at least about 40%, or at least about 50%, or at least about 60%, or at least about 70%, or at least about 80%, or at least about 90% or up to and including 100% increase, or any increase of 10% to 100% as compared to a reference level, or at least about 2-fold, or at least about 3-fold, or at least about 4-fold, or at least about 5-fold, or at least about 10-fold, or any increase of between 2-fold and 10-fold or more as compared to a reference level.

The term "statistically significant" or "significance" refers to statistical significance, typically meaning at least two standard deviations (2SD) from a reference level. The term refers to statistical evidence that there is a difference. It is defined as the probability of making a decision to reject a null hypothesis when the null hypothesis is true.

As used herein, unless otherwise specified, the terms "weight percent," "wt%" and "wt.%" are used interchangeably to indicate the weight percent of a given component based on the total weight of the composition in which the component is the given component. That is, all wt% values are based on the total weight of the composition, unless otherwise specified. It is understood that the sum of the wt% values of all components in the disclosed compositions or formulations is equal to 100. Alternatively, if the wt% values are based on the total weight of a subset of the components in the composition, it is understood that the sum of the wt% values for the specified components in the disclosed composition or formulation is equal to 100.

As used herein, the term "effective amount" refers to an amount sufficient to effect the desired modification of the physical properties of a composition or material. For example, an "effective amount" of a temperature reducing composition refers to an amount sufficient to achieve a desired improvement in a property modulated by the temperature reducing composition, e.g., achieve a desired Qmax enhancement as compared to the absence of an effective amount of yarn or fabric. The specific level in wt% required to be an effective amount in the composition will depend on a variety of factors including the amount and type of polymer and yarn, the fabric application, and the like.

As used herein, the terms "optional" or "optionally" mean that the subsequently described event or circumstance may or may not occur, and that the description includes instances where said event or circumstance occurs and instances where it does not.

As used herein, the term "micron-sized" includes surfaces having measurable features in the range of about 1 μm to about 1000 μm.

As used herein, the term "nanoscale" includes surfaces having measurable characteristics in the range of about 1nm to about 1000 nm.

As used herein, the term "nanoparticle" includes nanoscale deposits of homogeneous or heterogeneous materials. The shape of the nanoparticles may be regular or irregular, and may be formed from a plurality of co-deposited particles that form a composite nanoscale particle. The shape of the nanoparticles may be generally spherical or have a composite shape formed from a plurality of co-deposited generally spherical particles. Exemplary shapes of nanoparticles include, but are not limited to, spherical, rod-shaped, elliptical, cylindrical, disk-shaped, and the like. In some embodiments, the nanoparticles have a substantially spherical shape.

As used herein, unless otherwise specified, reference to an element, for example, "core component comprises Al, Ca, Cu, Fe … … Zr" or "core component comprises aluminum, calcium, copper, iron … … zirconium", is intended to include any form or any valence of the element appropriate for a given compound or material of which it is a constituent. That is, it is to be understood that if a composition or material contains a particular element as an ionic compound, reference to that element in the composition or material includes the ionic form of the element in its typical oxidation state; if the composition or material comprises an element as a covalent compound, a covalent bond form of the element is included; and if the composition or material comprises an element in an oxidation state of 0, such as Al as metallic aluminum, the elemental form (i.e., oxidation state of 0) is suitable or adaptable to the specified form.

As used herein, the term "transition metal" refers to an element whose atoms have a partially filled d sublayer or can generate cations with an incomplete d sublayer, typically found in groups 3-12, 4-7 of the periodic table of elements. Exemplary, but non-limiting, transition metals include titanium, vanadium, chromium, manganese, iron, cobalt, nickel, copper, zinc, yttrium, zirconium, silver, tungsten, platinum, and gold.

As used herein, "nanosilver" and "nanosilver oxide" are used interchangeably to refer to silver oxide (i.e., silver (I) oxide, silver (II) oxide, or a combination thereof), wherein the silver oxide is in a form that substantially comprises particles, powder, or a combination thereof, wherein the particles and/or powder are nano-sized. I.e., particles or powders, typically have a size of about 1nm to about 1000nm, as the case may be.

As used herein, the term "denier" or abbreviated "d" will be understood as a relative measure of the fineness (or linear density) of a fiber or yarn. Denier is numerically equivalent to the weight in grams of material per 9,000 meters of length. The term "dtex" is another measure of fiber fineness, which corresponds to the grammage of a 10,000 meter long material.

As used herein, "multicomponent" refers to fibers that are composed of more than one polymer.

As used herein, the term "fiber" refers to any long, elongated structure that can be carded, combed, or otherwise formed into threads or filaments. The fibers may comprise natural materials (e.g., cotton, linen, or wool) or man-made materials (e.g., nylon, polyester). Fibers are materials having an aspect ratio greater than about 10. Fibers are generally classified according to their fineness. Fibers are generally defined as having a fiber fineness of greater than about 15 denier, typically greater than about 30 denier. Fine denier fiber generally refers to a fiber having a fineness of less than about 15 denier. Examples of fibers include "staple fibers," a term well known in the textile art. Reference to "fiber" in "fiber" can mean or include a single fiber or a plurality or plurality of fibers, as the case may be. The plurality of fibers may comprise fibers of different compositions or may be substantially uniform in composition. Thus, by way of illustration, reference to "natural fibers" or "synthetic fibers" can mean and can include such types of individual fibers, or can mean any number or plurality of such fibers, and they can be included in threads, felts, yarns, woven materials, and the like, all as would be apparent from the context.

The fibers may be synthetic fibers or natural or organic fibers. As is well known to those skilled in the art, the smoothness of the outer surface varies significantly between different fibers. Thus, the outer surface of the fibers may be smooth or rough. By way of example only, rayon, such as polyester fibers, typically have a smooth outer surface. In contrast, natural fibers, such as cotton, typically have a rough outer surface. One consequence of the roughness of the outer surface is that a rough surface requires more fluid per unit diameter to completely cover the surface.

As used herein, "fiber" refers to any of a variety of types of substances that form the basic elements of textiles, characterized by a flexible, macroscopically homogeneous body with a high aspect ratio and a small cross-section, and may include one or more fibrous materials (e.g., fibers or filaments). It is understood that "fiber" includes "filament".

As used herein, "filaments" generally refers to continuous fibers of very long length, while "staple fibers" refers to fibers of finite length. The staple fibers may be natural fibers or fibers cut from, for example, filaments.

As used herein, "natural fiber" refers to fibers obtained from natural sources, such as cellulosic and proteinaceous fibers, or fibers formed by the regeneration or processing of naturally occurring fibers and/or products. Natural fibers are not intended to include fibers formed from petroleum products. Natural fibers include fibers formed from cellulose, such as cotton fibers, and regenerated cellulose fibers, commonly referred to as rayon, or acetate fibers derived by reacting cellulose with acetic acid and acetic anhydride in the presence of sulfuric acid. As used herein, "natural fiber" is intended to include any form of natural fiber, including individual filaments, as well as fibers present in yarns, fabrics, and other textiles, while "individual natural fiber" is intended to refer to individual natural filaments.

The filaments are typically formed by: polymer pellets or another polymer source are melted and then forced through an extrusion die to produce continuous fibers. The filaments may be a single continuous extrudate, or may be chopped extrudates, such as to form staple fibers. Such fibers may then be directly texturized (which is not common) or may be combined with other filaments to form a long tow, and the resulting tow may then be texturized.

As used herein, "composite fiber" refers to a continuous fiber in which two different polymers are intimately adhered to each other along the length of the fiber. In some cases, a composite filament is a filament or fiber composed of at least two different polymers that have been woven together to form a single filament or fiber. The term "different polymer" means that each of the at least two polymer components is arranged in different substantially constantly positioned zones across the cross-section of the composite fiber and extends substantially continuously along the length of the fiber. Composite fibers are distinguished from fibers extruded from a homogeneous blend of molten polymeric materials that do not form distinct polymeric regions. The at least two different polymer components useful herein may be chemically different polymers, or they may be chemically the same polymer but have different physical properties, such as tacticity, intrinsic viscosity, melt viscosity, die swell, density, crystallinity, and melting or softening point. One or more of the polymer components in the composite fiber may be a blend of different polymers. The composite fibers may have a fiber cross-section such as side-by-side, sheath-core eccentric, sheath-core concentric, or other suitable cross-section.

As understood herein, "filament" and "yarn" or "filament bundle" which will be considered to be a single strand of synthetic fiber or polymer extrudate are structures comprising a plurality of filaments bonded together.

The term "yarn" refers to a structure comprising a plurality of fibers that have been twisted, woven, or otherwise joined together to form a yarn, and may include staple yarns, continuous filament yarns, and yarns of the core-spun yarn structure. The strands that have been twisted, woven or otherwise joined together may be of natural or synthetic material, such as wool, nylon or polyester, in a form suitable for sewing, knitting, weaving or otherwise interlacing to form a woven fabric. Generally, "yarn" refers to the product obtained when the fibers are aligned. The yarn is a relatively long product with a relatively small cross-section. The yarn may be a single yarn (i.e., having one yarn strand), or a multi-strand yarn, such as a 2-strand yarn comprising two individual yarns twisted together or a 3-strand yarn comprising three yarn strands twisted together. In various aspects, the disclosed composite fibers are used to make the disclosed yarns. The disclosed yarns may be formed using staple fibers, using continuous fibers, or a combination thereof.

As used herein, "multifilament" refers to a yarn consisting of a plurality of continuous filaments or strands, as opposed to a monofilament as one strand. Most textile filament yarns are multifilament.

As used herein, "CSY" and "core spun yarn" are used interchangeably to refer to a yarn made by twisting fibers around one or more core fibers or filaments to conceal the core fibers or filaments.

As used herein, "FDY" and "fully drawn yarn" are used interchangeably to refer to a filament yarn in which the draw ratio is normal such that the polymer molecules are fully longitudinally oriented.

As used herein, "POY" and "partially oriented yarn" are used interchangeably to refer to a filament yarn having a draw ratio less than normal such that the polymer molecules are only partially machine direction oriented.

As used herein, the term "filament yarn" refers to a yarn comprised of more than one fiber filament running the entire length of the yarn. Filament yarns may also be referred to as multifilament yarns. The structure of the filament yarn is affected by twist and in some cases also by fiber deformation. The properties of filament yarns may be affected by the yarn structure, the inter-fiber friction that makes up the fibers, and the properties of the making up the fibers. In some embodiments, the yarn structure and recombinant protein fiber properties are selected to impart various properties to the resulting yarn. The properties of the yarn may also be affected by the amount of fibers (i.e., filaments) in the yarn. The filament yarns disclosed herein may be multifilament yarns. Throughout this disclosure, "filament yarn" may refer to flat filament yarn, textured filament yarn, drawn filament yarn, undrawn filament yarn, or filament yarn of any construction.

As used herein, the term "staple yarn" refers to a yarn made by twisting staple fibers together to make a cohesive yarn (or thread, or "singles").

The amounts of the foregoing temperature reducing compositions were those determined by performing elemental analysis and quantitative compositional analysis in the skin and core components using a Field Emission Scanning Electron Microscope (FESEM), which was performed by a FEI Teneo scanning electron microscope (FEI, inc., Hillsboro, Oregon, US) equipped with a super large area detector for energy dispersive spectroscopy (150mm Oxford XMaxN; Oxford Instruments, Concord, massachusesetts, US) for energy dispersive spectroscopy. The Aztec Energy software (oxford instruments) was used to provide elemental analysis capabilities. The analysis area is selected under the "scan image" option. The raw elemental analysis was performed under the "acquire spectra" option and the final average analysis was displayed under the "fit spectra tool".

Table 5 (next).

The data in table 5 shows that the representative disclosed fabrics have surprisingly superior thermal properties, exhibiting enhanced Qmax values of up to 41% and 57%, respectively, for the knitted and woven fabric examples. The thermal conductivity is increased by up to 10.3 times (see: 333W/Km for a representative disclosed fabric example 2 thermal conductivity²Whereas the conventional 100% rayon fabric in comparative example 1 was 32.3W/Km²) Improvements in drying and wicking behavior were also observed for the woven and knitted representative examples. For example, the disclosed representative fabric exhibits a drying time as fast as 500% than the sample (see: the drying time for representative disclosed fabric example 2 is 2.86 minutes, whereas conventional 100% rayon fabric comparative example 1 is over 14.44 minutes). The improved drying rate is also improved. The foregoing improvements are achieved when 100% cotton yarn is used in the warp weave but the disclosed double covered yarn is incorporated in the weft weave. Some of the data in table 5 are also plotted and shown in fig. 7 to 9, which show Qmax, drying rate and wicking behavior (time in minutes for water level to reach 20mm in length) of examples 1 to 4 compared to conventional samples comparative examples 1 to 3.

Overall, the disclosed representative fabrics show surprisingly significant improvements in many properties and attributes compared to conventional denim fabrics.
