Description

TECHNICAL FIELD

[0001] The present invention relates generally to the field of odor control compositions and textiles treated therewith. More specifically, the odor control compositions comprise a non-volatile triglyceride of plant origin that binds and / or neutralizes organic malodor molecules; and a high surface area essential mineral element (HSAEM) that binds and / or neutralizes organic malodor molecules for a prolonged period of time. In certain aspects, the odor control compositions are not intended for consumer use and / or application to textiles by a consumer. Rather, the textiles are treated with the odor control compositions during the manufacturing process to form treated textiles, wherein the treated textiles bind and / or neutralize organic malodor molecules for a prolonged period of time (e.g., up to twenty-five (25) wash cycles, months, years, or any combination thereof). BACKGROUND

[0002] The current field of textile odor reduction on textile materials (e.g., dry textile materials and articles) is limited in options and formulations, primarily utilizing heavy metals or nanomaterials to reduce specific odors. These heavy metal-based formulations and nanomaterials have many drawbacks, including causing damage to the environment. Specifically, these materials are often used in combination with polymers / polymer blends to adhere to textiles, but over time, these metals wash out of the textiles and leach into the soil and ground water, which are harmful to plants and animals at high concentrations. Further, WO 2015 / 167221 and WO 2002 / 090481 disclose various formulations of perfumes, laundry liquids, and deodorants applied to textiles by a consumer to impart temporary / transient odor control and / or odor masking properties. However, these formulations do not withstand repeated washing / cleaning and do not provide odor control and / or odor masking for a prolonged period of time. SUMMARY

[0003] Accordingly, there is a need to provide environmentally friendly odor control compositions / formulations that avoid the use of heavy metals and nanomaterials. In certain aspects, the environmentally friendly odor control compositions / formulations disclosed herein are equally effective, if not more effective, than the currently known heavy metal and nanomaterial compositions. The compositions, articles, and methods disclosed herein overcome the problems observed with the above-mentioned heavy metal and nanomaterial compositions by providing environmentally friendly compositions that utilize a combination of non-volatile triglycerides of plant origin and zeolites that synergistically interact with each other to reduce (by binding and neutralizing and / or reducing the odor associated with certain organic malodors) certain organic malodors (i.e., odors typically associated with human body odor, including odorous human body secretions and / or byproducts produced by bacteria and / or yeast found on the human body) on textile materials for a prolonged period of time. The organic malodors include, for example, isovaleric acid, ammonia, acetic acid, and nonenal.

[0004] Further, unlike the above compositions of heavy metals and nanomaterials, the compositions disclosed herein remain in the textile for a longer period of time than formulations comprising heavy metals and nanomaterials, as the disclosed compositions are wash durable. This wash durability advantageously allows the disclosed compositions to remain in the textile for a long period of time (e.g., 25 wash cycles, months, or up to a year) and impart odor control in and on the textile, reducing the odor associated with isovaleric acid, ammonia, acetic acid, and nonenal. Without wishing to be bound by theory, it is believed that the insolubility of the plant-derived non-volatile triglyceride and the high surface area of the zeolite prevent the disclosed compositions from washing out of the textile material / fabric, allowing for repeated use and sustained odor control of the textile material to which the disclosed compositions are applied for a prolonged period of time.

[0035] Implementations of the present invention may include one or more of the above features and configurations or any combination thereof.

[0036] Other features, aspects, and advantages of the invention will be set forth in the detailed description below, and some of these will become apparent to those skilled in the art from these detailed descriptions or by practicing the invention as described herein. It should be understood that the foregoing overview and the following detailed description present various embodiments of the invention and are intended to provide an overview or framework for understanding the nature and features of the claimed invention. Detailed Implementation

[0037] The invention will now be described in more detail with reference to the following working examples, which illustrate exemplary embodiments of the invention. However, the invention can be embodied in many different forms and should not be construed as limited to the representative embodiments set forth herein. These exemplary embodiments are provided so that this disclosure will be thorough and complete, fully conveying the scope of the invention and enabling those skilled in the art to make, use, and practice the invention.

[0038] Furthermore, the term “or” as used in this disclosure and the appended claims is intended to mean an inclusive “or” rather than an exclusive “or.” That is, unless otherwise stated or the context clearly indicates, the phrase “X employs A or B” is intended to refer to any natural inclusive arrangement. Specifically, the phrase “X employs A or B” is satisfied in any of the following cases: X employs A; X employs B; or X employs both A and B. Additionally, the absence of a quantifier preceding an element as used in this application and the appended claims should generally be interpreted as meaning “one or more than one / a kind or more than one” unless otherwise stated or the context clearly indicates a singular form. Throughout the specification and claims, unless the context requires otherwise, the following terms have at least the meaning explicitly relevant herein. The meanings determined below are not necessarily limiting of these terms, but merely illustrative examples of them. The meaning of the absence of a quantifier preceding an element can include plural references, and the meaning of “in…” can include “in…”, “at…”, and / or “on…” unless the context clearly indicates otherwise. The phrase “in one embodiment” as used herein does not necessarily refer to the same embodiment, although it may refer to the same embodiment.

[0039] Concentration, quantity, and other numerical data may be expressed or presented in range format herein. It should be understood that this range format is used solely for convenience and brevity, and therefore should be flexibly interpreted to include not only the explicitly listed values ​​as range boundaries, but also all individual values ​​or subranges contained within that range, as if each value and subrange were explicitly listed. For example, a numerical range of “about 1 to about 5” should be interpreted to include not only the explicitly listed values ​​of about 1 to about 5, but also individual values ​​and subranges within the specified range. Thus, the numerical range includes individual values ​​such as 2, 3, and 4, and subranges such as 1 to 3, 2 to 4, and 3 to 5, as well as 1, 2, 3, 4, and 5 individually. The same principle applies to ranges that list only one value as a minimum or maximum value. Furthermore, this interpretation should apply regardless of the breadth of the range or the characteristics described.

[0040] "High surface area essential mineral elements (HSAEM)" includes those with a specific surface area (SSA) greater than 250 m². 2 / g(250m 2 / g to 500m 2 / g, more preferably 300m 2 / g to 500m 2 / g) of minerals. Examples of one or more HSAEMs include clays and clay materials, more specifically zeolites and / or aluminosilicates, most preferably chalcogenide and / or pentasil zeolite.

[0041] The “plant-derived nonvolatile triglycerides” disclosed herein are mixtures of saturated and polyunsaturated 12- to 20-carbon fatty acids (C12 to C20 fatty acids). “Plant-derived” means the source of the triglycerides or oils; they are derived from plants, as opposed to animal or synthetic sources. “Non-volatile” means triglycerides that do not evaporate at room temperature (25°C), for example, with a boiling point above 100°C, preferably above 150°C, and more preferably above 200°C. Plant-derived nonvolatile triglycerides (also referred to as essential oils or oils in this specification) include castor oil, aloe vera oil, hemp seed oil, and linseed oil, more preferably castor oil as the primary plant-derived nonvolatile triglyceride in the disclosed compositions, and, if present, aloe vera oil as a secondary plant-derived nonvolatile triglyceride. In some respects, castor oil is the primary plant-derived nonvolatile triglyceride, and it is a non-aromatic oil. The fatty acid profile of castor oil contains at least 85% to 95% ricinoleic acid and other fatty acids. For example, castor oil contains other fatty acids besides ricinoleic acid, including linoleic acid, oleic acid, stearic acid, palmitic acid, linolenic acid, and dihydroxystearic acid, comprising 5% to 15% of the remaining castor oil (Safety Data Sheet, Alnor, August 2023). Castor oil has a boiling point above 300°C and a flash point above 230°C. Furthermore, castor oil has a hydroxyl content of 160 to 168 (Technical Data Sheet, Alnor, April 2012). In some respects, aloe vera oil is a minor plant-derived nonvolatile triglyceride in the disclosed compositions. Aloe vera oil contains an aromatic fatty acid profile. The aloe vera oil used in this article contains 0.1% to 10% Aloe Barbadensis leaf extract and 90% to 99.9% rapeseed oil (Cosmetic Ingredient Information Sheet, HALLSTAR, February 2020), and may also contain antioxidants (i.e., 0.1% to 0.4% tocopherol). Aloe Barbadensis leaf extract contains a variety of compounds, including phenolic compounds and dicarboxylic acids. The fatty acid profile of rapeseed oil contains an average of 60 wt% oleic acid, 20 wt% linoleic acid, and 10 wt% linolenic acid (Reference Module in Food Science, VJ Barthet, 2016), with the remaining 10% being other fatty acids. Rapeseed oil has a boiling point above 300°C and a flash point above 220°C (Safety Data Sheet, HALLSTAR, May 2015). In some respects, hemp seed oil and flaxseed oil are non-volatile triglycerides from other plant sources that can be included in the disclosed compositions. Both hemp seed oil and flaxseed oil are non-aromatic oils.Hemp seed oil has a boiling point above 230 degrees Celsius and a flash point above 130 degrees Celsius (Safety Data Sheet, NHR Organic Oils, June 2017). Flaxseed oil has a boiling point above 100 degrees Celsius and a flash point above 280 degrees Celsius (Safety Data Sheet, NHR Organic Oils, November 2020). The common fatty acids in these plant-derived non-volatile triglycerides are linoleic acid and linolenic acid.

[0042] "Owf," or fabric weight percentage, is commonly used in the field and for batch processes. The amount of chemical finishing agent to be applied is typically expressed as a weight percentage based on the original fabric weight. This relationship is abbreviated as %owf (fabric weight percentage), i.e., %OWF = [(chemical weight / fabric weight) * 100] / liquid carryover %. For example, if a chemical is to be applied to 400 kg of fabric at 3% owf with a liquid carryover of 80%, then 15 kg of the chemical (3% of 400 kg at 80% liquid carryover) would be used.

[0043] "Permanent adhesion" or "long-lasting adhesion" is used here to indicate that the composition remains in textiles for at least 25 wash cycles, which could be months or even years, depending on the number of washes.

[0044] Odor control concentrate composition

[0045] This document discloses an odor-controlling concentrate composition (applied prior to textile materials) that is applied (e.g., subsequently diluted and permanently applied via padding or dyeing) to and / or used to treat textile materials to reduce, bind, and / or neutralize odors and / or organic malodor molecules (secreted and / or excreted by the human body) on the textile materials over a prolonged period (e.g., 25 wash cycles, several months, or up to one year). The disclosed concentrate composition is environmentally friendly and, if not more effective, at the same level as currently known compositions for use in the textile field to form treated textile materials / treated textiles containing heavy metals and nanomaterials for odor control and reduction.

[0046] Specifically, the odor-controlling concentrate composition comprises a combination of a plant-derived nonvolatile triglyceride and one or more zeolites. The odor-controlling concentrate compositions disclosed herein also contain water and may further contain one or more alkali metal salts. The odor-controlling concentrate composition is a liquid under ambient conditions, more preferably an emulsion (e.g., a water-in-oil emulsion or an oil-in-water emulsion, depending on the water and oil content of the particular concentrate composition).

[0047] The concentration of plant-derived nonvolatile triglycerides in the odor-controlling concentrate composition is from 18 wt% to 40 wt% of the composition, wherein any endpoint falling within this range may serve as an endpoint of an additional range, which may include, for example, 20 wt% to 35 wt%, 25 wt% to 40 wt%, 25 wt% to 30 wt%, or 18 wt% to 30 wt%. In some aspects, the plant-derived nonvolatile triglycerides include aloe vera oil, castor oil, hemp seed oil, linseed oil, rapeseed oil, or any combination thereof. In some aspects, the plant-derived nonvolatile triglycerides include at least two of aloe vera oil, castor oil, hemp seed oil, rapeseed oil, and linseed oil. In some aspects, the plant-derived nonvolatile triglycerides include at least three of aloe vera oil, castor oil, hemp seed oil, rapeseed oil, and linseed oil. When two plant-derived nonvolatile triglycerides are present in the composition, the oils may be present in a ratio of 5:1 to 1:5, 3:1 to 1:3, or 1:1. In some respects, plant-derived nonvolatile triglycerides include aloe vera oil, castor oil, hemp seed oil, and linseed oil. As discussed further below, when diluted and applied to textile materials, each of the aforementioned plant-derived nonvolatile triglycerides controls odor by binding to, reducing, and / or neutralizing odor molecules (e.g., isovaleric acid, ammonia, nonenal, and / or acetic acid) and / or odors associated with the presence of these odor molecules, while also adhering one or more zeolites to the textile material.

[0048] Furthermore, the concentration of one or more zeolites included in the odor-controlling concentrate composition is from 10 wt% to 50 wt% of the composition, wherein any endpoint falling within this range may serve as endpoints of an additional range, which may include, for example, 15 wt% to 50 wt%, 20 wt% to 45 wt%, 25 wt% to 40 wt%, or 30 wt% to 40 wt%. Zeolites are preferred due to their high surface area and ability to bind, neutralize, and / or reduce odor molecules (e.g., ammonia, nonenal, acetic acid, and / or isovaleric acid) and / or odors associated with the presence of odor molecules. In some preferred aspects, the zeolite is chabazite and / or pentasil zeolite. Furthermore, one or more zeolites disclosed herein are provided in the disclosed compositions as polydisperse particles of 0.1 µm to 10 µm, more preferably 0.5 µm to 5 µm, which advantageously allows the disclosed plant-derived nonvolatile triglycerides to permanently fix and / or solidify the zeolite onto and / or within the textile material. Zeolite particles exceeding the highest point mentioned above should be avoided because they are coarse and easily abraded when applied to textile materials (and will negatively affect the feel / sense), which will adversely reduce the odor control effect; and one or more zeolite particles below the lowest point mentioned above should be avoided because regulations restrict the use of nanoparticles on textile materials (due to potential skin absorption and toxicological effects).

[0049] In some respects, the odor control concentrate composition comprises aloe vera oil, castor oil, hemp seed oil, flaxseed oil or any combination thereof, at a concentration of 25 wt% to 40 wt% of the total weight of the composition; and zeolite at a concentration of 10 wt% to 50 wt% of the total weight of the composition.

[0050] In some respects, the plant-derived nonvolatile triglycerides and one or more zeolites are present relative to each other in a ratio of 3:1 to 1:3, 2:1 to 1:2, more preferably 1.5:1 to 1:1.5, and most preferably 1:1. The plant-derived nonvolatile triglycerides disclosed herein, when present at the above concentrations and / or ratios, advantageously serve to adhere one or more zeolites (e.g., permanent adhesion and / or long-term adhesion – adhesion over 25 wash cycles, months or years) to textile materials (during and after the composition is applied to the textile material), thereby achieving desired odor control and reduction by binding and / or neutralizing organic molecules, while simultaneously adhering one or more zeolites to the textile material.

[0051] In some aspects, the odor control concentrate composition also comprises an alkali metal salt, wherein the alkali metal salt is preferably sodium lactate, sodium bicarbonate, or a combination thereof. When present in the concentrate composition, the concentration of the alkali metal salt is from 1.5 wt% to 15 wt% of the odor control concentrate composition. The alkali metal salt helps maintain the pH of the odor control concentrate at 4.0 to 7.5. The alkali metal salt helps capture IVA, nonenal, and acetic acid odor substances in the treated textile / fabric material. In some aspects, the concentration of zeolite is always higher than that of the alkali metal salt, and the ratio of zeolite to alkali metal salt is from 2:1 to 20:1, more preferably from 10:3 to 10:1. If the concentration of the alkali metal salt in the concentrate composition exceeds the disclosed amount, and ultimately on the treated textile material, the ability of zeolite to capture odors, especially ammonia, will be significantly reduced, and the pH of the treatment may become too alkaline, which will interfere with the integrity and visual properties of the textile material.

[0052] The odor control concentrate composition may further comprise one or more surfactants, binders, thixotropic agents, dispersants, defoamers, or any combination thereof to facilitate the dispersion of the aforementioned chemical components within the odor control concentrate composition. One or more surfactants may include, but are not limited to, ethoxylated alcohols, polyethylene glycol dilaurate or polyethylene glycol dioleate, sorbitan laurate, sorbitan oleate or sorbitan stearate, alkyl ethoxysulfates / salts or aryl ethoxysulfates / salts, sulfonates / salts and alkyl sulfates / salts, and alcohol ethoxylates / propoxylate copolymers, wherein the concentration in the odor control concentrate composition is from 0.5 wt% to 8 wt%. Similarly, the dispersant in the odor control concentrate composition may include, but is not limited to, acrylic resins, maleic acid soybean oil, triglyceride caprylate, polylactic acid / ricinoleate copolymer, polyethylene glycol, stearyl alcohol polyether-20, cetearyl stearate, polyglycerol stearate, polyglycerol distearate, sodium stearoyl lactylate, distearate dimethyl ammonium chloride, etc., with a concentration of 1 wt% to 8 wt% in the odor control concentrate composition. Similarly, the binder in the odor control concentrate composition may include, but is not limited to, acrylic adhesives, polyester adhesives, polyurethane adhesives, polyolefin adhesives, styrene-acrylic adhesives, with a concentration of 10 wt% to 30 wt% in the odor control concentrate composition. Similarly, the thixotropic agent in the odor control concentrate composition may include, but is not limited to, synthetic or natural layered silicates, clay, cellulose, acrylates / salts, carbomer, xanthan gum, pyrolytic silica, polyquaternium salts, polysorbates; with a concentration of 0.01 wt% to 1 wt% in the odor control concentrate composition. Similarly, defoamers in odor control concentrates may include, but are not limited to, polysiloxanes, silicone emulsions or silicone oils, alkyl polyacrylates / salts and alkyl aryl polyethers.

[0053] While the odor control concentrate can be an oil-in-water emulsion or an oil-in-water emulsion, in some embodiments, an oil-in-water emulsion is preferred. In preparing either type of emulsion, two separate phases are initially prepared: an oil phase and an aqueous phase. In the oil phase, zeolite is mixed with plant-derived non-volatile triglycerides, along with dispersants, surfactants, and defoamers. Simultaneously with mixing, these components are ground or homogenized to reduce the zeolite size. Specifically, high-shear mixing / grinding continues until the zeolite becomes polydisperse particles of 0.1 µm to 10 µm, more preferably 0.5 µm to 5 µm. Furthermore, high-shear mixing of the zeolite with the plant-derived non-volatile triglycerides, along with the dispersants and surfactants, is performed for a predetermined period of time, such that the zeolite particles are coated (e.g., partially or completely coated, preferably completely coated) by the plant-derived non-volatile triglycerides so that the zeolite remains in the inner phase when emulsified in the aqueous phase mentioned below. When further preparing the above emulsion, the aqueous and oil phases are prepared separately. The aqueous phase comprises water and surfactants (preferably nonionic surfactants) and thixotropic agents mixed therein. The aqueous phase contains one or more nonionic surfactants to form an oil-in-water emulsion. The nonionic surfactant preferably has an HLB value of 8 to 13. Examples of nonionic surfactants include, but are not limited to, ethoxylated alcohols, polyoxyethylene castor oil, polyoxyethylene hydrogenated castor oil, polyethylene glycol dilaurate or polyethylene glycol dioleate, sorbitan laurate, sorbitan oleate, or sorbitan stearate. Thixotropic agents are used to prevent emulsion dehydration and shrinkage – they provide a physical barrier to prevent emulsion droplets from colliding with each other, increasing the stability of the emulsion.

[0054] After preparing the oil and aqueous phases described above, a homogenizer (Silverson L5M-A) is used to mix the two phases for 15 to 45 minutes at a speed of 2500 to 5000 rpm to form an oil-in-water emulsion or a water-in-oil emulsion, depending on and determined by the total oil and water content in the emulsion. During this mixing / homogenization step, one or more of the alkali metal salts disclosed above may be added at the concentrations described above. The two phases are mixed for a predetermined period of time until, for the oil-in-water emulsion, the oil phase is uniformly mixed in the aqueous phase, thereby forming the odor control concentrate composition disclosed above with the above concentrations and components; or, for the water-in-oil emulsion, the aqueous and oil phases are uniformly mixed to form the odor control concentrate composition disclosed above with the above concentrations and components.

[0055] As shown in the working examples, some of the odor control concentrate compositions disclosed herein are oil-in-water emulsions containing at least 36% water as a diluent, with a concentration of plant-derived nonvolatile triglycerides of 18 wt% to 40 wt%, more preferably 18 wt% to 30 wt%, and a concentration of zeolite of 10 wt% to 50 wt%, more preferably 10 wt% to 30 wt%, and most preferably 12.5 wt% to 20 wt%. Furthermore, in some respects, alkali metal salts may be included in the concentrate composition at any of the aforementioned concentrations. Additionally, the zeolite coated with plant-derived nonvolatile triglycerides is preferably uniformly dispersed in the aqueous phase of the oil-in-water emulsion such that the zeolite does not precipitate from the odor control concentrate composition.

[0056] Method of applying an odor control composition to a textile material

[0057] The disclosed odor-control concentrate composition can be diluted, for example, with water to form an odor-control composition, which is then applied (permanently applied) to a desired textile material by padding or dyeing. When done in this manner, about 0.2 wt% to about 10 wt% of the odor-control concentrate composition is diluted in water (e.g., 90 wt% to 99.8 wt%), and the diluted solution (odor-control composition) is then applied to the textile material by padding or dyeing. After the composition is applied to the textile material, the textile material is dried, heat-set, and / or cured to form a dry textile material (also referred to as "treated textile material") that reduces, binds, and / or neutralizes odor molecules and / or odors associated with the presence of odor molecules.

[0058] For example, when using the padding method, the padding solution is prepared by combining a concentrate of an odor control / textile coating composition with water, wherein approximately 2% to 10% is the concentrate of the composition and 90% to 98% is water. The pH of the padding solution should be between 4.0 and 7.5. The padding solution is applied to the desired textile material using a continuous roller, wherein the textile is immersed in the padding solution path for one to fifteen seconds. Subsequently, the padded textile is cured / dried in an infrared (IR) dryer at a temperature of 130°C to 180°C for a period of 30 seconds to 5 minutes to obtain a dry textile material in which the odor and / or organic malodor molecules (secreted and / or excreted by the human body) persist for a long period of time (e.g., 25 wash cycles, several months, or up to one year).

[0059] For example, in the immersion dyeing method, the immersion bath is prepared by combining a concentrate of the odor control / textile composition with water, wherein approximately 0.2% to 0.5% is the concentrate and 99.5% to 99.8% is water. The pH of the immersion bath should be between 4.0 and 6.5. Immersion dyeing can be carried out in a laboratory dyeing machine containing the desired textile material, such as the Lobomat BFA-24 Werner Mathis AG. Immersion conditions may include the following: a liquor ratio of 10:1, an immersion temperature of 65°C to 135°C, a residence time at the immersion temperature of 40 minutes, and a heating and cooling rate of 2°C / min. After dyeing, the treated textile material is rinsed and then cured / dried in an IR dryer at a temperature of 130°C to 180°C for a period of 30 seconds to 5 minutes to obtain a dry textile material. The dry textile material contains odors and / or organic malodor molecules (secreted and / or excreted by the human body) that persist for a long period of time (e.g., 25 wash cycles, several months or up to one year).

[0060] In some respects, plant-derived nonvolatile triglycerides, more specifically castor oil and / or aloe vera oil, provide a variety of benefits during and after the application of the odor control composition (i.e., a diluted form of the odor control concentrate composition) to the textile material. Specifically, given the proportions and / or concentrations disclosed herein, the plant-derived nonvolatile triglycerides, more specifically castor oil and / or aloe vera oil, act as co-dispersants of zeolite during application to the textile material. At the proportions and / or concentrations disclosed herein, the plant-derived nonvolatile triglycerides, more specifically castor oil and / or aloe vera oil, encapsulate and stabilize the zeolite during the application of the composition to the textile material. The plant-derived nonvolatile triglycerides, more specifically castor oil and / or aloe vera oil, also act as carriers for the zeolite, allowing the zeolite to penetrate into and / or adhere to the textile material during and / or after the application of the odor control composition to the textile material. Furthermore, plant-derived nonvolatile triglycerides, more specifically castor oil and / or aloe vera oil, advantageously act as plasticizers, softening the textile material during composition application, thereby promoting deeper penetration of, for example, zeolite, one or more alkali metal salts, and nonvolatile triglycerides into the textile material. This, in turn, provides more persistent odor control in the textile material (e.g., binding, neutralizing, and reducing odors associated with the presence of ammonia, nonenal, isovaleric acid, and / or acetic acid). In some respects, the zeolite is large enough to only partially penetrate the textile fibers, such that a portion of the zeolite is exposed on the textile / fabric surface and can be used to capture odor substances. Plant-derived nonvolatile triglycerides, more specifically castor oil and / or aloe vera oil, further improve the lubricity of textile materials (e.g., one or more fabrics) during and after composition application by reducing and / or minimizing tactile defects (e.g., surface roughness and / or abrasiveness) associated with zeolites on the outer surfaces of textile materials (e.g., the outer surface of woven fabrics). This further improves dry rubbing fastness and minimizes friction on the outer surfaces of textile materials, thereby preventing and / or reducing premature wear of textile materials after application of the odor control composition.

[0061] Furthermore, the alkali metal salts included in the composition help capture isovaleric acid, acetic acid, and nonenal odor substances during and after the application of the composition to the textile. As mentioned above, sodium lactate and / or sodium bicarbonate can be used as alkali metal salts. However, sodium lactate is the most preferred alkali metal salt, considering that the treated fabric / textile must have a pH of 4.0 to 7.5. The fabric pH should be 4 to 7.5 so that the fabric does not irritate the skin. Furthermore, when the fabric pH exceeds 7.5, phenolic yellowing is likely to occur, which is aesthetically unappealing. Conversely, when the fabric pH drops below 4, one or more dyes in the textile material (e.g., fabric) become soluble and leach from the fabric. Specifically, sodium bicarbonate has a pKa of approximately 6.4, which is significantly higher than that of sodium lactate. In padding or dyeing processes, due to its relatively high pKa, the conjugate acid (carbonic acid) of sodium bicarbonate will react rapidly with water to produce carbon dioxide at pH close to 6.4 or lower. The pH of padding solutions prepared with sodium bicarbonate tends to be 6.75 to 7.25, resulting in a pH of 7.0 to 7.75 for textiles (e.g., treated textiles and / or fabrics). Therefore, the upper limit of the pH range for textile materials treated with compositions containing sodium bicarbonate (e.g., pH 7.5 to 7.75) exceeds the preferred post-treatment fabric pH of 4.0 to 7.5. In contrast, sodium lactate has a pKa of approximately 3.8, significantly lower than that of sodium bicarbonate, and sodium lactate converts to its conjugate acid (lactic acid) at much lower pH levels (e.g., when the pH is close to 3.8 or lower). The pH of padding solutions prepared with sodium lactate tends to be 5.0 to 6.0, resulting in a pH of 6.0 to 6.75 for textiles (treated textiles and / or fabrics), which falls entirely within the post-treatment fabric pH range of 4.0 to 7.5. In addition, when the pH of textile materials (e.g., clothing) exceeds 7.5, prolonged contact with the textile materials can often cause skin irritation due to their alkalinity.

[0062] Use of a composition

[0063] This document also discloses the use of the described composition for permanent application to textile materials for odor control. The foregoing aspects regarding the composition and method also apply to this use.

[0064] Textile material having an odor control composition thereon

[0065] This document also discloses one or more dry textile materials (also referred to as "treated textiles" or "treated textile materials") on which one of the above compositions is applied, for example, by padding or dyeing as described above. Dry textile materials having an odor-controlling / textile coating composition applied to them bind, neutralize, and / or reduce the duration of odors associated with organic odors / malodorous molecules, particularly compared to the same dry textile material not treated (and / or not having the compositions disclosed herein applied).

[0066] In this respect, the dry textile material comprises: a plant-derived nonvolatile triglyceride applied to the dry textile material at a concentration of 0.5% owf to 5.0% owf, more preferably 0.75% owf to 3.5% owf, most preferably 1% owf to 3% owf, or 1.5% owf or 1.75% owf to 2% owf, based on the weight percentage of the fabric; and zeolite applied to the textile at a concentration of 0.25% owf to 3% owf, or 0.25% owf to 2% owf or 0.25% owf to 1.75% owf, more preferably 0.5% owf to 1.5% owf, most preferably 0.75% owf to 1.25% owf, based on the weight percentage of the fabric. In this regard, the alkali metal salts (e.g., sodium bicarbonate and sodium lactate) applied to the textiles are 0.08% owf to 0.6% owf, 0.09% owf to 0.5% owf, 0.1% owf to 0.5% owf, 0.1% owf to 0.4% owf, 0.1% owf to 0.3% owf, 0.1% owf to 0.2% owf, and 0.1% owf to 0.15% owf. In this regard, plant-derived nonvolatile triglycerides and zeolite are present on and / or in the dry textile material in a ratio of 3:1 to 1:3, 2:1 to 1:2, more preferably 1.5:1 to 1:1.5, and most preferably 1:1.

[0067] Given the aforementioned concentrations and proportions, the dry textile material and / or the composition applied to the dry textile material controls odor by binding, neutralizing, and / or reducing odors associated with ammonia, acetic acid, isovaleric acid, and / or nonenal, particularly compared to untreated textile materials. Specifically, compared to untreated textile materials, the dry textile material binds and neutralizes 75% to 100%, more preferably 80% to 100%, of ammonia, and / or compared to untreated textile materials, the dry textile material binds and neutralizes 75% to 100%, more preferably 80% to 100%, of acetic acid, compared to untreated textile materials, the dry textile material binds and neutralizes 75% to 100%, more preferably 80% to 100%, of isovaleric acid, and / or compared to untreated textile materials, the dry textile material binds and neutralizes 75% to 100%, more preferably 80% to 100% of nonenal. In some respects, plant-derived nonvolatile triglycerides, more specifically castor oil and / or aloe vera oil, bind, neutralize, and / or reduce the odor associated with the presence of isovaleric acid and / or nonenal.

[0068] In some preferred aspects, the textile materials disclosed herein, including dry textile materials, are woven or non-woven textile materials. In some preferred embodiments, the textile materials and / or dry textile materials are knitted / woven fabrics comprising polyester, nylon, rayon, cotton, or any combination thereof. In some aspects, the textile materials / dry textile materials comprise a fabric weight of 20 gsm to 400 gsm (grams per square meter). It should be further understood that heavier fabric weights will absorb more of the disclosed compositions described above (e.g., during and after padding and / or during and after dyeing), resulting in dry textile materials having better, longer-lasting odor control / capture capabilities.
