Description

Technical Field

[0001] The present invention relates generally to the field of odor control compositions and textiles treated therewith, and more particularly to odor control compositions comprising benzoic acid and exhibiting durable antimicrobial and odor control properties. Background Art

[0002] Current standards for antimicrobial and / or odor reduction of textile materials include the use of heavy metals and / or nanomaterials to reduce specific odors. Formulations containing heavy metals and / or nanomaterials can be harmful to the environment as they wash out of textiles and leach into soil and groundwater. Therefore, safer compounds with potent antimicrobial and odor control properties are preferred. Summary of the invention

[0023] Embodiments of the present invention may include one or more or any combination of the above-mentioned features and configurations.

[0024] Additional features, aspects, and advantages of the present invention will be set forth in the following detailed description, some of which will be apparent to those skilled in the art from the description or recognized by practicing the invention as described herein. It should be understood that both the foregoing general description and the following detailed description present various embodiments of the present invention and are intended to provide an overview or framework for understanding the nature and character of the claimed invention. The accompanying drawings are included to provide a further understanding of the present invention and are incorporated into and constitute a part of this specification. DETAILED DESCRIPTION

[0025] The present invention will now be described more fully below with reference to working examples showing exemplary embodiments of the present invention. However, the present invention can be implemented in many different forms and should not be construed as being limited to the representative embodiments described herein. Exemplary embodiments are provided to make this disclosure both thorough and complete, and will fully convey the scope of the present invention and enable those of ordinary skill in the art to make, use and practice the present invention.

[0026] In addition, 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 specified or clear from the context, the phrase "X employs A or B" is intended to mean any natural inclusive arrangement. That is, the phrase "X employs A or B" satisfies any of the following situations: X employs A; X employs B; or X employs both A and B. Unless otherwise specified or clear from the context to be in the singular form, the articles "a" and "an" used in this application and the appended claims should generally be interpreted to mean "one or more". Throughout the specification and claims, unless the context dictates otherwise, the following terms have at least the meanings explicitly associated herein. The meanings determined below do not necessarily limit the terms, but merely provide illustrative examples of the terms. Unless the context clearly indicates otherwise, the meaning of "a / a", "an", and "the" may include plural references, and the meaning of "in" may include "in / at / on". The phrase "in one embodiment" as used herein does not necessarily refer to the same embodiment, although it may.

[0027] Concentration, amount and other numerical data can be represented or presented in the format of range in this article.It should be understood that such range format is used only for convenience and simplicity, and therefore should be flexibly interpreted as not only including the numerical value clearly listed as the limit of the range, but also including all individual numerical values ​​or sub-ranges contained in the range, just as each numerical value and sub-range are clearly listed.As an example, the numerical range of "about 1 to 5" should be interpreted as not only including the value of about 1 to about 5 clearly listed, but also including the single value and sub-range in the indicated range.Therefore, included in this numerical range are individual values ​​(such as 2, 3 and 4) and sub-ranges (such as 1 to 3, 2 to 4 and 3 to 5, etc.) and individual 1, 2, 3, 4 and 5.The same principle applies to the scope of only listing one numerical value as the minimum or maximum value.In addition, no matter how wide the described range or feature is, this explanation should be applicable.

[0028] "Owf" or textile weight percent is commonly used in the field and in batch processing, and the amount of chemical finish to be applied is usually expressed as a weight percentage based on the original textile weight. This relationship is abbreviated as %owf (textile weight percent), in pad coating, %OWF = [(chemical weight / textile weight)*100] / wet pick-up %; and in exhaust coating, %OWF = (chemical weight / textile weight)*100. For example, in padding, if a chemical is applied to 400 kg of textile at 3% owf, wet pick-up = 80%, then 15 kg of chemical will be applied to the textile (3% of 400 kg at 80% wet pick-up); in exhaust dyeing, if a chemical is applied to 400 kg of textile at 3% owf, then 12 kg of chemical will be applied.

[0029] As used herein, the term "quat silane," "quaternarysilane," or "quaternary ammonium silane" refers to a class of antimicrobial compounds having silane, quaternary ammonium, and a carbon chain containing at least eight carbons or more.

[0030] As used herein, "coating" refers to a composition that changes the surface of an article or imparts a certain property to the surface of an article. The coating can be covalently bonded to the surface of the article. Additionally or alternatively, the coating can be bonded to the surface and / or within the surface of the article by electrostatic forces or van der Waals forces.

[0031] Antimicrobial and odor control textile coating compositions

[0032] Disclosed herein are antimicrobial and odor control textile coating compositions that are configured to be applied to textile materials to impart antimicrobial and / or odor control properties over a long period of time (e.g., twenty-five wash cycles, fifty wash cycles, several months, or up to a year). The disclosed antimicrobial and odor control compositions are environmentally friendly and are as effective as currently used heavy metal and nanomaterial formulations, and in some cases even more effective.

[0033] The antimicrobial and odor control textile coating compositions disclosed herein utilize benzoic acid as the primary antimicrobial and odor control component. The compositions described herein exhibit improved thermal stability and durable antimicrobial and odor control properties when applied to textiles using heat setting and curing methods at elevated temperatures compared to untreated textiles (textile materials without any composition applied thereto).

[0034] Benzoic acid is generally difficult to formulate and / or apply to textiles / textile materials due to the fact that it sublimates and slightly degrades at high temperatures when heat set on the textiles / textile materials. Therefore, when applied to textiles / textile materials by padding or exhaust methods, the final heat setting / curing temperature should not exceed 130°C. However, typical heat setting temperatures for polyesters are 130°C to 170°C. Therefore, low temperature curing limits the use of benzoic acid on textile materials such as polyester. Therefore, in order to utilize benzoic acid in textile coating compositions, lower temperatures and / or additional components must be used to prevent sublimation or degradation of the benzoic acid.

[0035] The first antimicrobial and / or anti-odor textile coating composition utilizes benzoic acid as the primary antimicrobial and odor control component and uses terephthalic acid as a crosslinking agent. The composition prevents benzoic acid from sublimating and / or degrading by anchoring terephthalic acid between the textile and the benzoic acid to form a permanent bond. The terephthalic acid binds the benzoic acid to the textile fibers through crosslinking or covalent bonding, thereby increasing the thermal stability of the benzoic acid and improving performance and wash durability.

[0036] The first antimicrobial and / or anti-odor textile coating composition can be a solid composition at ambient temperature, since benzoic acid has little water solubility and terephthalic acid is insoluble in water. In a water-based application process, the first antimicrobial and odor control composition may require heating and / or the addition of a dispersant to facilitate coating on the textile material. Dispersants include, but are not limited to, fatty amines, alkylnaphthalene sulfonates, and more preferably ethoxylated alcohols. Ethoxylated alcohols are preferred because they are stable under acidic conditions in the first antimicrobial and / or anti-odor textile coating composition. In some aspects, the dispersant is present in an amount of 0.1 wt % to 2 wt % based on the total weight of the composition.

[0037] The first textile coating composition can have an operable weight ratio of benzoic acid to terephthalic acid of 2:1 to 8:1, with any endpoint falling therein being an endpoint of an additional range; additional ranges include more preferably 3:1 to 7:1, and most preferably 4:1 to 6:1. Outside of this ratio, if properly coated, antimicrobial and odor control effects can still be observed; however, thermal stability may be reduced and / or wash durability may be reduced. In addition, if the amount of benzoic acid is reduced, the antimicrobial effect of the composition will be reduced.

[0038] The first antimicrobial and / or anti-odor textile coating composition can be solid at ambient temperature. In a solid first antimicrobial and / or anti-odor textile coating composition, benzoic acid can be present in the first antimicrobial and / or anti-odor textile coating composition at 65% to 90% by weight of the composition, wherein any endpoint falling therein can be used as an endpoint of an additional range; additional ranges can include, for example, 70% to 85%, 75% to 85%, and 75% to 80%. In some aspects, the benzoic acid is a benzoate, such as sodium benzoate.

[0039] In the solid first antibacterial and / or anti-odor textile coating composition, terephthalic acid can be present in the first antibacterial and / or anti-odor textile coating composition at 10 wt % to 35 wt % of the total weight of the composition, wherein any endpoint falling therein can be used as an endpoint of an additional range; additional ranges can include, for example, 15 wt % to 20 wt %, 15 wt % to 30 wt %, and 20 wt % to 25 wt %.

[0040] The first antibacterial and / or deodorant textile coating composition can be a liquid or liquid dispersion at ambient temperature. The first antibacterial and / or deodorant textile coating composition can include 90% to 98% by weight of water. The first antibacterial and / or deodorant textile coating composition can also include 0.1% to 2% by weight of a dispersant to help dissolve benzoic acid and / or terephthalic acid. Benzoic acid can be present in the first antimicrobial and / or deodorant textile coating composition with 1.3% to 9% by weight of the composition, and any endpoints falling therein can be used as endpoints of additional ranges; Additional ranges can include, for example, 1.5% to 8.5% by weight, 2% to 7% by weight, and 3% to 5% by weight. In some aspects, benzoic acid is a benzoate, such as sodium benzoate. Terephthalic acid can be present in the first antimicrobial and / or anti-odor textile coating composition at 0.2 wt % to 3.5 wt % of the total weight of the composition, wherein any endpoint falling therein can be used as an endpoint of an additional range; additional ranges can include, for example, 0.3 wt % to 2 wt %, 0.5 wt % to 1.5 wt %, and 0.75 wt % to 1.3 wt %.

[0041] The second antimicrobial and / or anti-odor textile coating composition also utilizes benzoic acid and quaternary ammonium silane as the main antimicrobial and odor control components. It is well known that quaternary ammonium silane has antimicrobial properties, but in the present case, it is used as a solubilizer and stabilizer to keep the benzoic acid in solution, thereby being grind-friendly. In addition to the antimicrobial and odor control properties, the second antimicrobial and / or anti-odor textile coating composition also imparts water resistance to the treated textile article. Organic solvents such as methanol, isopropanol and acetone can also dissolve benzoic acid. However, when it comes to water-based textile wet processes, benzoic acid recrystallizes and becomes solid again, which makes the treatment of textiles uneven. Therefore, organic solvents alone are not sufficient to stabilize benzoic acid. The second antimicrobial and / or anti-odor textile coating composition encapsulates benzoic acid within the coating by forming a layer or coating on the surface that is covalently bonded to the polyester surface, preventing sublimation and / or degradation of benzoic acid.

[0042] The second antimicrobial and / or anti-odor textile coating composition can have a weight ratio of benzoic acid to quaternary ammonium silane of 2:5 to 1:4, wherein any endpoint falling therein can be used as an endpoint of an additional range. Outside of this ratio, if properly coated, antimicrobial and odor control effects can still be observed; however, thermal stability, solubility, and / or washing durability may be reduced.

[0043] In the second antibacterial and / or anti-odor textile coating composition, benzoic acid can be present in the second antibacterial and / or anti-odor textile coating composition at 20% to 30% by weight of the total weight of the composition, wherein any endpoint falling therein can be used as the endpoint of an additional range; additional ranges include 22% to 26%, 23% to 28%, 24% to 26%, 22% to 24%, and 23% to 25%. In certain aspects, the benzoic acid is a benzoate, such as sodium benzoate.

[0044] In the second antibacterial and / or deodorant textile coating composition, the quaternary ammonium salt silane can be present in 70% to 80% by weight of the total weight of the composition, wherein any endpoint falling therein can be used as the endpoint of an additional range; the additional range includes: 73% to 78% by weight, 75% to 80% by weight, 75% to 78% by weight, and 72% to 78% by weight. The quaternary ammonium salt silane can be 3-(trimethoxysilyl)propyl dimethyl octadecyl ammonium chloride, chloropropyl trimethoxy silane, methanol, octadecyl dimethyl tertiary amine, or a combination thereof. In some aspects, the quaternary ammonium salt silane is a mixture of 3-(trimethoxysilyl)propyl dimethyl octadecyl ammonium chloride, chloropropyl trimethoxy silane, methanol, and octadecyl dimethyl tertiary amine. In certain aspects, the quaternary ammonium silane comprises 74.9 wt % to 69.1 wt % of 3-(trimethoxysilyl)propyldimethyloctadecyl ammonium chloride, 16 wt % of chloropropyltrimethoxysilane, 10 wt % to 19.5 wt % of methanol, and 2 wt % of octadecyldimethyl tertiary amine. Although the quaternary ammonium silane is also considered an antimicrobial agent, benzoic acid is the main antimicrobial agent and odor control component in the composition.

[0045] The second antibacterial and / or anti-odor textile coating composition can include 80% to 95% by weight of water. Benzoic acid can be present in the second antibacterial and / or anti-odor textile coating composition at 1% to 6% by weight of the composition, wherein any endpoint falling therein can be used as the endpoint of an additional range; the additional range can include, for example, 1.2% to 5.6% by weight, 1.5% to 5% by weight, and 2% to 4% by weight. In some aspects, benzoic acid is a benzoate, such as sodium benzoate. The quaternary ammonium salt silane can be present in the second antibacterial and / or anti-odor textile coating composition at 3.5% to 16% by weight of the total weight of the composition, wherein any endpoint falling therein can be used as the endpoint of an additional range; the additional range can include, for example, 3.7% to 5.6% by weight, 4% to 14% by weight, and 4.3% to 13% by weight.

[0046] Method of applying antimicrobial and odor control composition

[0047] As further discussed and shown in the running examples, during the coating process, the antibacterial and / or deodorant textile coating composition can be applied (permanently applied) to the desired textile material. The antibacterial and / or deodorant textile coating composition can be applied to the desired textile using an impregnation process. Additionally or alternatively, the antibacterial and / or deodorant textile coating composition can be applied to the desired textile using a padding process. The coating process described herein makes the composition uniform or even forms a coating on the textile, which causes the textile to have no discoloration or surface texture after application, and has consistent antibacterial and deodorant properties on the textile.

[0048] For example, for the first antibacterial and / or anti-odor textile coating composition, when using a padding method, a padding bath is prepared by mixing the first antibacterial and odor control composition with water, and the padding bath is about 2-10% of the first antibacterial and / or anti-odor textile coating composition and water. In some aspects, heating is used to make the first antibacterial and / or anti-odor textile coating composition enter the solution. In addition or alternatively, a dispersant can be used to help dissolve the first antibacterial and / or anti-odor textile coating composition. The dispersant can be added to the composition when formulated. Alternatively, the dispersant can be used during the coating process. The dispersant can be added at a concentration of 0.1% to 2% by weight based on the total weight of the composition. The padding bath is padded on the desired textile material, and then cured / dried at a temperature of 110°C to 170°C in a tenter frame or dryer for at least 45 seconds, up to 5 minutes, to obtain a dry textile material that can resist the growth of bacteria on the textile material and control odor for a long time (e.g., 25 wash cycles, 50 wash cycles, several months or up to one year).

[0049] For example, for the first antibacterial and / or anti-odor textile coating composition, when using the dip dyeing method, the dip dyeing bath is prepared by mixing the first antibacterial and / or anti-odor textile coating composition with water, and the dip dyeing bath is about 2-10% concentrate and water. In some aspects, heating is used to make the first antibacterial and / or anti-odor textile coating composition enter the solution. In addition or alternatively, a dispersant can be used to help dissolve the first antibacterial and / or anti-odor textile coating composition. Dipping can be carried out in a beaker dyeing machine containing the desired textile material, such as Lobomat BFA-24Werner Mathis AG. Dipping conditions may include the following: the liquid ratio (ratio of coating bath to textile material) is 10 to 1, the dip dyeing temperature is 110°C to 140°C, and the residence time at the dip dyeing temperature is 20 minutes to 50 minutes. The textile and liquid medium are subsequently cooled to a temperature of 40°C to 70°C. After dyeing, the treated textile material is rinsed and then dried in a dyeing machine (optionally in an IR dryer) at a temperature of room temperature (about 20°C) to 190°C for at least 45 seconds up to overnight to obtain a dry textile material that can resist the growth of bacteria on the textile material and control odor for a long time (e.g., 25 wash cycles, 50 wash cycles, several months or up to a year).

[0050] Once the first antimicrobial and / or anti-odor textile coating composition is applied to the textile, an antimicrobial and anti-odor textile material is produced, wherein the benzoic acid forms the outermost surface of the antimicrobial and anti-odor textile material, and the terephthalic acid forms an intermediate layer between the benzoic acid and the surface of the textile material. The coating process results in the formation of covalent bonds between the terephthalic acid and the textile chains, and also between the terephthalic acid and the benzoic acid.

[0051] For example, for the second antibacterial and / or anti-odor textile coating composition, when the padding method is used, the padding bath is prepared by mixing the second textile coating composition and water. The padding bath contains about 5-20% of the second antibacterial and / or anti-odor textile coating composition. The padding bath is padded onto the desired textile material and then cured / dried in a tenter frame or dryer at a temperature of 110° C. to 170° C. for a minimum of 45 seconds and up to 5 minutes to obtain a dried textile material that can resist the growth of bacteria on the textile material and control odor for a long time (e.g., 25 wash cycles, 50 wash cycles, several months or up to a year).

[0052] For example, for the second antibacterial and / or anti-odor textile coating composition, when the dip dyeing method is used, the dip dyeing bath is prepared by mixing the second antibacterial and / or anti-odor textile coating composition and water. The dip dyeing bath contains about 5-20% of the second textile coating composition. Dipping can be carried out in a beaker dyeing machine containing the desired textile material, such as Lobomat BFA-24 Werner Mathis AG. Dipping conditions may include the following: the liquid ratio (ratio of the coating bath to the textile material) is 10: 1, the dip dyeing temperature is 110°C to 140°C, and the residence time at the dip dyeing temperature is 20 minutes to 50 minutes.

In some aspects, textile material / dry textile material includes the textile weight of 20-400gsm (grams / square meter). It should also be understood that heavier textile will absorb more above-mentioned disclosed composition (for example, during padding and after and / or during and after impregnation), so that textile material has better odor control / capture ability for a long time.

[0059] Working Example

[0060] As a first comparative example, benzoic acid was coated onto polyester at 6% owf by dip-dyeing and cured at 170°C. The antimicrobial textiles were tested AATCC TM 100 to determine the log reduction of Klebsiella pneumoniae before washing and after 25 home washes. The data from AATCC TM 100 are shown in Table 1 below. Benzoic acid showed little or no antimicrobial properties before washing and no antimicrobial properties after washing. This is due to the thermal instability of benzoic acid.

[0061] Table 1

[0062]

[0063]

[0064] A second comparative example was evaluated. The second comparative composition had a quaternary ammonium silane mixture without benzoic acid. The second comparative composition contained: 72 weight percent 3-(trimethoxysilyl)propyldimethyloctadecyl ammonium chloride, 16 weight percent chloropropyltrimethoxysilane, and 2 weight percent octadecyldimethyl tertiary amine in methanol. The second comparative composition was coated onto polyester by dip-dyeing at 9% owf and cured at 170°C. The antimicrobial textiles were tested AATCCTM 100 to determine the log reduction of Klebsiella pneumoniae and Staphylococcus aureus before washing and after 25 home washes. The data for AATCC TM 100 are shown in Table 2 below. When the composition was formulated without benzoic acid, there was no log reduction in the growth of Klebsiella pneumoniae. In addition, when the composition did not contain benzoic acid, the composition did not have any wash durability. After 25 home washes, the log reduction in the growth of Staphylococcus aureus almost disappeared.

[0065] Table 2

[0066]

[0067] A first antimicrobial and / or anti-odor textile coating composition was prepared by mixing 83.3 wt% benzoic acid and 16.75 wt% terephthalic acid. The first antimicrobial and / or anti-odor textile coating composition was dissolved in water, applied to polyester by dip-dyeing at 6% owf, and cured at 170°C. The antimicrobial textiles were tested AATCC TM 100 to determine the log reduction of Klebsiella pneumoniae and Staphylococcus aureus before washing and after 25 home washes. The data for AATCC TM 100 are shown in Table 3 below. When benzoic acid is formulated with terephthalic acid, the benzoic acid has improved thermal stability and durability because the terephthalic acid binds / crosslinks the benzoic acid to the polyester fibers of the textile material.

[0068] Table 3

[0069]

[0070] A second antimicrobial and / or anti-odor textile coating composition was prepared by mixing 25 wt% benzoic acid and 75 wt% quaternary ammonium silane (72 wt% 3-(trimethoxysilyl)propyldimethyloctadecyl ammonium chloride, 16 wt% chloropropyltrimethoxysilane, and 2 wt% octadecyldimethyl tertiary amine). The second antimicrobial and / or anti-odor textile coating composition was dissolved in water, applied at 9% owf by padding, and cured at 170°C. The antimicrobial textile test AATCC TM100 was performed to determine the log reduction of Klebsiella pneumoniae and Staphylococcus aureus before washing, after 25 home washes, and after 50 home washes. The data for AATCC TM100 are shown in Table 4 below. When benzoic acid was formulated with the quaternary ammonium silane, the textile showed an improved reduction in bacterial growth compared to the above comparative example. In addition, when formulated with the quaternary ammonium silane, the antimicrobial effect was extended after 25 home washes and 50 home washes. Benzoic acid is stabilized by quaternary ammonium silane, which forms a polymer structure when cured at high temperature, traps benzoic acid and prevents sublimation. Quaternary ammonium silane is an antimicrobial solution in itself. However, due to the characteristics of quaternary ammonium silane chemistry, it only shows antimicrobial properties when tested according to the ASTM E2149 test method (using accelerated laundry followed by salt-methanol rinse). In this formulation, benzoic acid is still the key antimicrobial ingredient, while the quaternary ammonium silane is just a solubilizer. The performance of the treated textiles can be tested using any common antimicrobial method, including but not limited to AATCC TM 100, ISO 20743, and JIS L 1902. In addition, it can be washed with ordinary household laundry without the need for salt-methanol rinse. The water repellency of the textile treated with the second antimicrobial composition at 9% owf was determined using AATCC TM 22, with a score of 75, while the untreated textile scored 0.
