Odor control composition concentrate

Abstract

An odor-controlling concentrated composition comprising a plant-derived non-volatile triglyceride that binds and / or neutralizes organic odor molecules, and a zeolite that binds and / or neutralizes organic odor molecules. The odor-controlling concentrated composition may be diluted and applied to fibers / textile materials. Fibers to which the odor-controlling composition is applied and / or fibers treated with the odor-controlling composition bind, neutralize, and reduce odors associated with odor molecules over a long period of time (e.g., up to 25 wash cycles, several months, several years, or any combination thereof).

Description

Technical Field

[0001] The present invention generally relates to the field of odor control compositions and fibers treated with such compositions. More specifically, it relates to an odor control composition comprising a plant-derived non-volatile triglyceride that binds and / or neutralizes organic malodorous molecules and a high specific surface area essential mineral (HSAEM) that binds and / or neutralizes organic malodorous molecules over a long period of time. In certain embodiments, the odor control composition is not for consumers and / or is not applied to fibers by consumers. Rather, the fibers are treated with the odor control composition during the manufacturing process to become treated fibers that bind and / or neutralize organic malodorous molecules over a long period of time (e.g., 25 washing cycles, months, years, or any combination thereof).

Background Art

[0002] In current odor reduction technologies for fiber materials (dry fiber materials and textiles), the options and formulation designs are limited, and many of them use heavy metals and nanomaterials to reduce specific odors. These heavy metal-based formulations and nanomaterials have many drawbacks, including environmental problems. In particular, these materials are usually used in combination with polymer / polymer mixtures and adhere to fibers, but are washed away from the fibers over time and elute into soil and groundwater, becoming harmful to plants and animals at high concentrations. Furthermore, WO 2015 / 167221 and WO 2002 / 090481 disclose various fragrance formulations, washing formulations, and anti-odor formulations applied to fibers by consumers to obtain temporary / transient odor control and / or masking properties. However, these formulations cannot withstand repeated washing and cleaning, and odor control and masking do not continue over a long period of time.

Summary of the Invention

[0003] Therefore, there is a need to provide environmentally friendly odor control compositions / formulations that do not use heavy metals or nanomaterials. In certain embodiments, odor control compositions / formulations that are environmentally friendly and as effective as or better than known heavy metal / nanomaterial formulations are disclosed herein. The compositions, articles, and methods disclosed herein solve the above problems seen with heavy metals and nanomaterials by providing environmentally friendly compositions that reduce certain organic malodors (odors associated with body odor, including malodorous human secretions and / or by-products produced by bacteria and / or yeasts on the human body) of textile materials over a long period of time (by binding to and neutralizing / reducing odors associated with certain organic malodors). Organic malodors include, for example, isovaleric acid, ammonia, acetic acid, and nonenal.

[0004] Furthermore, unlike the heavy metal and nanomaterial compositions described above, the compositions disclosed herein are wash-resistant and therefore remain on the fibers longer than formulations containing heavy metals or nanomaterials. This wash resistance gives the compositions the advantage of remaining on the fibers for extended periods (e.g., 25 wash cycles, several months, or up to one year), controlling odors both inside and outside the fibers and reducing odors associated with isovaleric acid, ammonia, acetic acid, and nonenal. While not intended to be theoretical, it is believed that the insolubility of plant-derived non-volatile triglycerides and the high specific surface area of ​​zeolite prevent the compositions from being washed away from the textile material / fabric, allowing the textile material to which the compositions are applied to be reused and odor control to be maintained over extended periods.

[0005] In one embodiment, an odor-controlling concentration composition is disclosed, comprising (a) an effective amount of a plant-derived non-volatile triglyceride that binds and / or neutralizes organic odor molecules, and (b) an effective amount of a zeolite that binds and / or neutralizes organic odor molecules.

The fatty acids common to these plant-derived non-volatile triglycerides are linoleic acid and linolenic acid.

[0042] The terms "owf" and "cloth weight ratio" are commonly used in this technology and batch processes, and the amount of chemical finish applied is usually expressed as a weight percentage based on the original cloth weight. This relationship is abbreviated as %owf (cloth weight ratio), and %owf = [(chemical weight / cloth weight) * 100] / wet pick-up rate %. For example, when applying a chemical to 400 kg of cloth with a cloth weight ratio of 3% and a wet pick-up rate of 80%, 15 kg of chemical is used (3% of 400 kg with an 80% wet pick-up rate).

[0043] As used herein, the terms “permanently adhere” or “long-term adherence” refer to the composition remaining on the fibers for at least 25 wash cycles, and depending on the number of washes, it may remain for months or even years.

In some embodiments, the plant-derived non-volatile triglycerides include aloe oil, castor oil, hemp seed oil, and flaxseed oil. As will be further described below, each of the above-mentioned plant-derived non-volatile triglycerides, when diluted and applied to a fibrous material, not only 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 these odor molecules, but also adheres zeolite to the fibrous material.

[0047] Furthermore, the zeolite in the odor-controlling concentrated composition is present at a concentration of 10 wt% to 50 wt% of the composition (any endpoint within this range may be used as the endpoint of other ranges, such as 15 wt% to 50 wt%, 20 wt% to 45 wt%, 25 wt% to 40 wt%, and 30 wt% to 40 wt%). Zeolite is preferred because it has a high specific surface area and can bind, neutralize, and reduce odor molecules (e.g., ammonia, nonenal, acetic acid, and / or isovaleric acid) and / or odors associated with these odor molecules. In one preferred embodiment, the zeolite is chabazite and / or pentasyl. Furthermore, the zeolite disclosed herein is included in the disclosed composition as polydisperse particles measuring 0.1 μm to 10 μm, more preferably 0.5 μm to 5 μm, thereby having the advantage that the zeolite can be permanently fixed and / or retained on and / or within the fibrous material by the disclosed plant-derived non-volatile triglycerides. If the zeolite particles exceed the upper limit of the range described above, they become coarse and prone to peeling off the fibrous material after application (further negatively affecting the tactile feel) and impairing odor control, so such particles should be avoided. If the zeolite particles fall below the lower limit of the range described above, they should also be avoided because they violate regulations prohibiting the use of nanoparticles in fibrous materials (due to the risk of absorption into the skin and toxicity).

[0048] In one embodiment, the odor control concentration composition comprises aloe oil, castor oil, hemp seed oil, flaxseed oil, or any combination thereof, present at a concentration of 25 wt% to 40 wt% of the total weight of the composition, and zeolite, present at a concentration of 10 wt% to 50 wt% of the total weight of the composition.

[0049] In some embodiments, plant-derived non-volatile triglycerides and zeolites are present in a ratio of 3:1 to 1:3, preferably 2:1 to 1:2, more preferably 1.5:1 to 1:1.5, and most preferably 1:1. When the plant-derived non-volatile triglycerides disclosed herein are present in the above concentrations and / or ratios, they not only adhere the zeolite to the textile material (e.g., permanently and / or over a long period of time (25 wash cycles, several months, or several years)) when the composition is applied to the textile material (and after application), providing desired odor control, binding and / or neutralizing and reducing organic molecules, but also adhering the zeolite to the textile material.

[0050] In some embodiments, the odor control concentrate further contains an alkali metal salt, which is preferably sodium lactate, sodium bicarbonate, or a combination thereof. When the alkali metal salt is included in the concentrate, it is present at a concentration of 1.5 wt% to 15 wt% of the odor control concentrate. The alkali metal salt makes it easier to maintain the pH of the odor control concentrate between pH 4.0 and 7.5. The alkali metal salt makes it easier to capture odor substances such as IVA, nonenal, and acetic acid in the treated fibers / textile material. In some embodiments, zeolite is always present at a higher concentration than the alkali metal salt, with a zeolite-to-alkali metal salt ratio of 2:1 to 20:1, more preferably 10:3 to 10:1. If the concentration of alkali metal salt in the concentrate and, consequently, in the treated textile material exceeds the disclosed concentration, the odor (especially ammonia) capture ability of the zeolite decreases significantly, the pH of the treatment becomes alkaline, and this may affect the integrity and visual properties of the textile material.

[0051] The odor-controlling concentrated composition may further contain one or more surfactants, a binder, a thixotropic agent, a dispersant, an antifoaming agent, or any combination thereof, in order to facilitate the dispersion of the above-mentioned chemical components in the odor-controlling concentrated composition. Examples of one or more surfactants include, but are not limited to, ethoxylated alcohols, polyethylene glycol dilaurate or dioleate, sorbitan laurate, oleate or stearate, alkyl or aryl ethoxylated sulfates, sulfonates and alkyl sulfates, and alcohol ethoxylate / propoxylate copolymers in concentrations of 0.5 wt% to 8 wt% of the odor-controlling concentrated composition. Similarly, examples of dispersants in the odor-controlling concentrated composition include, but are not limited to, acrylic resins, maleated soybean oil, capric triglycerides, polylacto acid / ricinolate copolymers, polyethylene glycol, steareth 20, cetearyl glucoside polyhydroxystearate, polyglycerol stearate, polyglyceryl distearate, sodium stearoyl lactylate, and distearyldimethylammonium chloride, at concentrations of 1 wt% to 8 wt% of the odor-controlling concentrated composition. Similarly, examples of binders in the odor-controlling concentrated composition include, but are not limited to, acrylic binders, polyester binders, polyurethane binders, polyolefin binders, and styrene acrylate binders, at concentrations of 10 wt% to 30 wt% of the odor-controlling concentrated composition. Similarly, examples of thixotropic agents in the odor-controlling concentrated composition include, but are not limited to, synthetic or natural phyllosilicates, clays, celluloses, acrylates, carbomers, xanthan gums, pyrogenic silicas, polyquaterniums, and polysorbates in concentrations of 0.01 wt% to 1 wt% of the odor-controlling concentrated composition. Similarly, examples of defoaming agents in the odor-controlling concentrated composition include, but are not limited to, polysiloxanes, silicone emulsions or oils, alkyl polyacrylates, and alkylaryl polyethers.

[0052] The odor control concentrate may be an oil-in-water emulsion or a water-in-oil emulsion, but in some embodiments, an oil-in-water emulsion is preferred. When preparing either emulsion, two phases (an oil phase and an aqueous phase) are first prepared. In the oil phase, zeolite is mixed with a plant-derived non-volatile triglyceride, a dispersant, a surfactant, and an antifoaming agent. During mixing, these components are pulverized or homogenized to reduce the size of the zeolite. In particular, high-shear mixing / pulverization is continued until the zeolite becomes polydisperse particles of 0.1 to 10 μm, more preferably 0.5 to 5 μm. Furthermore, high-shear mixing of the zeolite with the plant-derived non-volatile triglyceride, dispersant, and surfactant is carried out over a predetermined period of time so that the zeolite particles are coated with the plant-derived non-volatile triglyceride (e.g., partially or completely coated (completely coated is preferred)), so that the zeolite is retained in the dispersed phase even when emulsified in the aqueous phase as described below. When preparing the emulsion described above, an aqueous phase is prepared separately from the oil phase. The aqueous phase contains water mixed with a surfactant (preferably a nonionic surfactant) and a thixotrope. The nonionic surfactant is included in the aqueous phase to produce 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-derived castor oil, polyoxyethylene-derived hydrogenated castor oil, polyethylene glycol dilaurate or dioleate, sorbitan laurate, oleate, or stearate. The thixotrope is useful in preventing syneresis of the emulsion, providing a physical barrier that prevents emulsion particles from colliding with each other and increasing the stability of the emulsion.

[0053] After preparing the oil and water phases as described above, these two phases are mixed using a homogenizer (Silverson L5M-A) at 2500-5000 rpm for 15-45 minutes to produce an oil-in-water emulsion or a water-in-oil emulsion. Whether it becomes an oil-in-water emulsion or a water-in-oil emulsion depends on the oil and water content in the emulsion. During the above mixing / homogenization, the alkali metal salt described above may be added at the described concentrations. In the case of an oil-in-water emulsion, the two phases are mixed for a predetermined time until the oil phase is homogeneously mixed with the water phase, resulting in the production of the odor-controlling concentrated composition having the described concentrations and components. In the case of a water-in-oil emulsion, the two phases are mixed for a predetermined time until the water phase is homogeneously mixed with the oil phase, resulting in the production of the odor-controlling concentrated composition having the described concentrations and components.

[0054] As shown in the examples, the odor-controlling concentrated compositions disclosed herein are oil-in-water emulsions comprising at least 36% water, 18 wt% to 40 wt% (more preferably 18 wt% to 30 wt%) of plant-derived non-volatile triglycerides of the composition, and 10 wt% to 50 wt% (more preferably 10 wt% to 30 wt%, most preferably 12.5 wt% to 20 wt%) of zeolite of the composition, wherein in some embodiments, alkali metal salts may be included in the concentrated composition at any of the above concentrations. Furthermore, the zeolite coated with plant-derived non-volatile triglycerides is preferably uniformly dispersed in the aqueous phase of the oil-in-water emulsion and does not separate from the odor-controlling concentrated composition.

[0055] (Method for applying odor control compositions to textile materials) The odor-controlling concentrated composition described above may be diluted with water or the like to produce an odor-controlling composition that can be (permanently) applied to a desired fiber material by a padding method or an exhaustion method. In this case, approximately 0.2 wt% to 10 wt% of the odor-controlling concentrated composition described above is diluted with water (for example, 90 wt% to 99.8 wt%), and this dilution (odor-controlling composition) is applied to the fiber material by a padding method or an exhaustion method. After the composition is applied to the fiber material, the fiber material is dried, heat-treated, and / or cured to obtain a dried fiber material (also called "treated fiber material") that reduces, binds, and / or neutralizes odor molecules and / or odors associated with odor molecules.

[0056] For example, when using the padding method, a pad bath is prepared by combining the concentration of the odor control composition / fiber coating composition with water. The pad bath consists of approximately 2-10% of the composition and 90-98% water. The pH of the pad bath is preferably 4.0-7.5. Using a continuous roller, the desired fiber material is padded into the pad bath, and the fibers are immersed in the pad bath for 1-15 seconds. The padded fibers are then cured / dried in an infrared (IR) dryer at 130°C-180°C for 30 seconds-5 minutes to obtain a dried fiber material that neutralizes odors and / or organic malodorous molecules (secretions and / or excretions from the human body) of the fiber material for a long period of time (e.g., 25 wash cycles, several months, or up to several years).

[0057] For example, in the exhaustion method, an exhaustion bath is prepared by combining the concentration of the odor control composition / fiber composition with water. The exhaustion bath consists of approximately 0.2-0.5% concentration and 99.5-99.8% water. The pH of the exhaustion bath is preferably 4.0-6.5. Exhaustion may be carried out in a beaker dryer (e.g., Lobomat BFA-24 from Werner Mathis AG) containing the desired fiber material. Exhaustion conditions include a bath ratio of 10:1, an exhaustion temperature of 65°C-135°C, a holding time at the exhaustion temperature of 40 minutes, and a heating / cooling rate of 2°C / min. After exhaustion, the treated fiber material is washed and cured / dried in an IR dryer at 130°C to 180°C for 30 seconds to 5 minutes to obtain a dried fiber material that neutralizes odors and / or organic malodorous molecules (secretions and / or excretions from the human body) for a long period of time (e.g., 25 wash cycles, several months, or up to several years).

[0058] In some embodiments, plant-derived non-volatile triglycerides (particularly castor oil and / or aloe vera oil) offer several advantages when applying odor-controlling compositions (i.e., diluted odor-controlling concentrated compositions) to and after application to textile materials. Specifically, in view of the ratios and / or concentrations disclosed herein, plant-derived non-volatile triglycerides (particularly castor oil and / or aloe vera oil) act as auxiliary dispersants for zeolites when applied to textile materials. At the ratios and / or concentrations disclosed herein, plant-derived non-volatile triglycerides (particularly castor oil and / or aloe vera oil) encapsulate the zeolite and stabilize it when the composition is applied to the textile material. Plant-derived non-volatile triglycerides (particularly castor oil and / or aloe vera oil) also act as carriers for the zeolite, allowing the zeolite to permeate and / or adhere to the textile material when the odor-controlling composition is applied to and / or after application to the textile material. Furthermore, plant-derived non-volatile triglycerides (particularly castor oil and / or aloe vera oil) have the added benefit of acting as plasticizers that soften the fibrous material when the composition is applied, thereby facilitating the penetration of zeolites, alkali metal salts, and non-volatile triglycerides deep into the fibrous material. As a result, it becomes possible to control odors in the fibrous material over a long period of time (e.g., by binding, neutralizing, and reducing odors associated with ammonia, nonenal, isovaleric acid, and / or acetic acid). In some embodiments, the zeolite is sized to only partially penetrate the fibrous fabric, so that some of the zeolite is exposed on the surface of the fiber / fabric, thereby capturing odor-causing substances. Plant-derived non-volatile triglycerides (particularly castor oil and / or aloe vera oil) also improve the slipperiness of textile materials (e.g., fabrics) both when the composition is applied to the textile material and after application, by reducing and / or minimizing the tactile disadvantages (e.g., surface roughness and / or grittiness) associated with the presence of zeolite on the outer surface of the textile material (e.g., the outer surface of a textile fabric).This improves dry crocking and minimizes friction on the outer surface of the fiber material, thus preventing and / or reducing premature wear of the fiber material after application of the odor control composition.

[0059] Furthermore, the alkali metal salts contained in the composition help to capture odor substances such as isovaleric acid, acetic acid, and nonenal when the composition is applied to the fiber material and afterward. As mentioned above, sodium lactate and / or sodium bicarbonate may be used as the alkali metal salt. However, considering that the pH of the treated cloth / fiber must be between 4.0 and 7.5, sodium lactate is the most preferred alkali metal salt. The pH of the cloth should be between 4.0 and 7.5 so that the cloth does not irritate the skin. Furthermore, if the pH of the cloth is greater than 7.5, phenolic yellowing is likely to occur, which is undesirable in appearance. On the other hand, if the pH of the cloth is lower than 4, the dye in the fiber material (cloth) may dissolve and leach out of the cloth. In particular, the pKa of sodium bicarbonate is about 6.4, which is much higher than the pKa of sodium lactate. Due to its relatively high pKa, when the pH approaches 6.4 during padding or exhaustion, the conjugate acid (carbonic acid) of sodium bicarbonate quickly reacts with water to produce carbon dioxide. Pad baths containing sodium bicarbonate often have a pH range of 6.75 to 7.25, from which fibers (e.g., treated fibers and / or treated fabrics) with a pH range of 7.0 to 7.75 are obtained. Therefore, the upper pH limit of fiber materials treated with compositions containing sodium bicarbonate (e.g., pH 7.51 to 7.75) exceeds the preferred pH range of pH 4.0 to 7.5 for treated fabrics. In contrast, the pKa of sodium lactate is approximately 3.8, which is considerably lower than the pKa of sodium bicarbonate, and sodium lactate is converted to its conjugate acid (lactic acid) at a lower pH (e.g., around pH 3.8). Pad baths containing sodium lactate often have a pH range of 5.0 to 6.0, from which fibers (treated fibers and / or treated fabrics) with a pH range of 6.0 to 6.75 are obtained. This falls within the preferred pH range of pH 4.0 to 7.5 for treated fabrics. Furthermore, if the pH of a textile material (e.g., clothing) exceeds 7.5, prolonged contact with the textile material often causes skin irritation due to its basic nature.

[0060] (Use of the composition) This specification also discloses the use of compositions permanently applied to fibrous materials to control odor. The embodiments described above with respect to compositions and methods also apply to uses.

[0061] (Fiber material to which odor control composition has been applied) This specification also discloses dry fiber materials (also referred to as "treated fibers" or "treated fiber materials") to which one of the compositions described above has been applied by methods such as padding or exhaustion. Dry fiber materials to which the odor control composition / fiber coating composition has been applied bind, neutralize, and / or reduce the odor associated with organic odor / malodorous molecules in the dry fiber material over a longer period of time than the same dry fiber material that has not been treated with (and / or to which the compositions disclosed herein have not been applied).

[0062] In this embodiment, the dry fiber material comprises a plant-derived non-volatile triglyceride applied to the dry fiber material at a concentration of 0.5 to 5.0%, more preferably 0.75% to 3.5%, most preferably 1% to 3%, or 1.5% or 1.75% to 2% by fabric weight, and a zeolite applied to the dry fiber material at a concentration of 0.25% to 3%, 0.25% to 2%, 0.25% to 1.75%, more preferably 0.5% to 1.5%, most preferably 0.75% to 1.25% by fabric weight. In this embodiment, the alkali metal salts applied to the fibers (e.g., sodium bicarbonate and sodium lactate) are present in amounts of 0.08% to 0.6%, 0.09% to 0.5%, 0.1% to 0.5%, 0.1% to 0.4%, 0.1% to 0.3%, 0.1% to 0.2%, and 0.1% to 0.15% by fabric weight. In this embodiment, plant-derived non-volatile triglycerides and zeolites are present on and / or within the dry fiber 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.

[0063] At the concentrations and ratios described above, the dried fiber material and / or the composition applied thereto control odor over a longer period of time compared to the untreated fiber material by binding, neutralizing, and / or reducing the odor associated with ammonia, acetic acid, isovaleric acid, and / or nonenal on the fiber material. Specifically, the dried fiber material binds and neutralizes 75% to 100%, more preferably 80% to 100%, of ammonia compared to the untreated fiber material, and / or the dried fiber material binds and neutralizes 75% to 100%, more preferably 80% to 100%, of acetic acid compared to the untreated fiber material, the dried fiber material binds and neutralizes 75% to 100%, more preferably 80% to 100%, of isovaleric acid compared to the untreated fiber material, and / or the dried fiber material binds and neutralizes 75% to 100%, more preferably 80% to 100%, of nonenal compared to the untreated fiber material. In some embodiments, plant-derived non-volatile triglycerides (particularly castor oil and / or aloe oil) bind to, neutralize, and / or reduce the odor associated with isovaleric acid and / or nonenal.

[0064] In a preferred embodiment, the fibrous material disclosed herein (including the dry fibrous material) is either a woven or nonwoven fibrous material. In a preferred embodiment, the fibrous material and / or dry fibrous material is a knitted or woven fabric containing polyester, nylon, rayon, cotton, or any combination thereof. In a preferred embodiment, the fabric weight of the fibrous material / dry fibrous material is 20 to 400 gsm (grams per square meter). Furthermore, it should be understood that the heavier the fabric, the more of the above-mentioned composition it will absorb (during and after padding and / or during and after exhaustion), resulting in a dry fibrous material that better controls / captures odors over a longer period.

[0065] (Examples) Table 1 shows exemplary compositions of the compositions disclosed herein (i.e., compositions 3-6, abbreviated as "Comp#3", "Comp#4", "Comp#5", and "Comp#6" in Tables 1-3) and comparative formulations (i.e., comparative formulations 1-2, abbreviated as "Comp#1" and "Comp#2" in Tables 1-3). Each composition shown in Table 1 (comparative compositions 1-2 and exemplary compositions 3-6) was applied by padding at a fabric weight ratio of 5% to a textured polyester interlock knit fabric made from filament yarn, at 150°C for 120 seconds. The fabric weight was 106 g / m2. The wet pick-up rate of the fabric was 100 wt%. The polyester fabric was Test Fabrics' #703, catalog number #1405003. The size of each sample was A4 size (210 mm × 297 mm). As shown in Table 1, comparative compositions 1 and 2 (abbreviated as "Comp#1" and "Comp#2" in Tables 1-3) do not contain alkali salts (e.g., sodium bicarbonate and sodium lactate) compared to exemplary compositions 3-6 (abbreviated as "Comp#3," "Comp#4," "Comp#5," and "Comp#6" in Tables 1-3). The OWF values ​​of fibers treated with each composition are shown in Table 2.

[0066] Composition #1 used Biovera® Aloe Vera Oil. Biovera® Aloe Vera Oil contains canola oil (CAS No. 120962-03-0) and aloe vera leaf extract (CAS No. 85507-69-3) (see pages 1-8 of the Safety Data Sheet issued December 11, 2015). Each composition used Alnor's castor oil (see Safety Data Sheet issued August 2, 2023). Laponite® RD was supplied by BYK (see Safety Data Sheet printed May 10, 2022). E-Sperse® 325 was supplied by Ethox Chemicals (see Technical Forum). Sodium lactate (60%) was Galaflow SL from Galactic (see the material safety data sheet revised on December 16, 2008, and the technical data sheet as of March 2024). Printol HFB was from DyStar® (see the product data sheet issued in May 2008). [Table 1] [Table 2]

[0067] After application to polyester, the reduction rates of four major malodorous compounds were measured for each composition. The reduction rate of isovaleric acid was measured according to ISO 17299-3. The reduction rate of ammonia was measured according to ISO 17299-2. The reduction rate of acetic acid was measured according to ISO 17299-2, and the reduction rate of nonenal was measured according to ISO 17299-3. As shown in Table 3, compositions 1 and 2, which did not contain sodium bicarbonate and sodium lactate, showed lower reduction rates of acetic acid than compositions 3-6. Compositions containing castor oil and zeolite, and further containing either sodium bicarbonate or sodium lactate, showed significant reduction rates for all of ammonia, nonenal, isovaleric acid, and acetic acid. [Table 3]

[0068] The wash durability of the treated textile materials was evaluated under the conditions specified in PHX AP0701. The treated textiles were washed for 10 wash cycles (HL). Each cycle consisted of 2 kg of material at a minimum temperature of 40°C, using 20 g of ECE (standard detergent 98 containing optical gloss), followed by low-temperature tumble drying. Two textile materials treated with Comp#5 were evaluated both before and after the 10 wash cycles. Table 4 shows the results regarding odor reduction retention. As shown in the table, even after 10 washes, the treated textile materials retained 27.4% to 93.9% of their odor reduction effect, showing a significant improvement compared to untreated PET even after 10 washes. [Table 4]

[0069] The foregoing description provides embodiments of the present invention for illustrative purposes only. It is assumed that similar functions can be performed and / or similar results can be achieved in other embodiments. All such equivalent embodiments and examples are within the scope of the present invention and are covered by the appended claims.
