Description

Technical Field

[0001] The present invention generally relates to odor control compositions and fibers treated with odor control compositions, and more particularly to odor control compositions containing benzoic acid and exhibiting persistent antibacterial and odor control properties.

Background Art

[0002] In current standards for fiber antibacterial and / or odor reduction of fiber materials, heavy metals and / or nanomaterials are used to reduce specific odors. Preparations containing heavy metals and / or nanomaterials can be washed away from the fibers and elute into soil and groundwater, which may harm the environment. Therefore, safer compounds with strong antibacterial and odor control properties are desired.

Summary of the Invention

[0003] Therefore, there is a need to provide effective and environmentally friendly antibacterial and / or odor control formulations without using heavy metals and nanomaterials.

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

[0024] Further features, aspects, and advantages of the present invention are described in the following detailed description, some of which will be readily apparent to those skilled in the art from this description or will be recognized by practicing the invention described herein. It should be understood that the above summary 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 claimed nature and characteristics of the invention. The accompanying drawings are included to provide a further understanding of the present invention and are incorporated as part of this specification. [Modes for carrying out the invention]

[0025] The present invention will be described more completely and in detail below with reference to embodiments illustrating the present invention. However, the present invention can be embodied in many different forms and should not be limited to the representative embodiments described herein. Embodiments are provided so that this disclosure is thorough and complete, so as to fully convey the scope of the present invention and so as to enable those skilled in the art to manufacture, use and practice the present invention.

[0026] Furthermore, the word “or” as used in this disclosure and the attached claims is not exclusive, but rather inclusive. That is, unless otherwise specified or evident from the context, the expression “X uses A or B” means any of the naturally included combinations. That is, the expression “X uses A or B” is satisfied by any of “X uses A,” “X uses B,” and “X uses both A and B.” Furthermore, the articles “a” and “an” as used in this application and the attached claims should be interpreted as meaning “one or more” unless otherwise specified or evident from the context. In the specification and claims, the following words have at least the meaning expressly related to this specification, unless the context indicates otherwise. The meanings described below are not necessarily limiting to the words, but are merely illustrative meanings of the words. The meanings of "a," "an," and "the" may include plural forms, and the meaning of "in" may include "in," "at," and / or "on" unless the context explicitly indicates otherwise. The expression "in one embodiment" as used herein does not necessarily refer to the same embodiment, although it may.

[0027] In this specification, concentrations, amounts, and other numerical data may be presented in a range format. Such a range format is used only for convenience and brevity, and it should be understood that not only the numerical values explicitly recited as the limiting values of the range, but also all individual numerical values and sub-ranges included within that range are to be construed as being included as if they were explicitly recited. For example, the numerical range of "about 1 to 5" should be construed as including not only the explicitly recited values of about 1 to about 5, but also individual numerical values and sub-ranges within that range. Thus, this range includes individual values such as 2, 3, 4, etc., sub-ranges such as 1 to 3, 2 to 4, 3 to 5, etc., and the individual 1, 2, 3, 4, 5. The same applies to ranges that recite one numerical value as the minimum or maximum value. Further, such an interpretation shall apply regardless of the breadth of the range or the characteristics being described.

[0028] The ratio based on "owf" or fabric weight is commonly used in the field of the present invention and in batch processes, and the amount of chemical finishing agent applied is usually expressed as a weight percentage based on the original fabric weight. This relationship is abbreviated as %owf (percent on weight of fabric), and in padding, %OWF = [(weight of chemical substance / weight of fabric)*100] / wet pickup rate %, and in exhaustion, %OWF = (weight of chemical substance / weight of fabric)*100. For example, when applying a chemical substance at 3%owf to 400 kg of fabric with a wet pickup rate of 80% by padding, 15 kg of chemical substance is applied to the fabric (3% of 400 kg at 80% pickup), and when applying a chemical substance at 3%owf to 400 kg of fabric by exhaustion, 12 kg of chemical substance is applied.

[0029] As used herein, the terms "quatsilane", "quaternary silane", or "quaternary ammonium silane" refer to a class of antibacterial compounds having a silane, a quaternary ammonium, and a carbon chain having at least 8 or more carbons.

[0030] As used herein, “coating” means a composition that alters the surface of an article or imparts a characteristic to the surface of an article. A coating may be covalently bonded to the surface of an article. In addition to or instead of covalent bonding, a coating may be bonded to the surface of an article and / or into the surface of an article by electrostatic or van der Waals forces.

[0031] (Antibacterial and odor-controlling fiber coating composition) This specification discloses antimicrobial and odor-controlling textile coating compositions configured to be applied to textile materials to impart antimicrobial and / or odor-controlling properties over a long period of time (e.g., 25 wash cycles, 50 wash cycles, several months, or up to one year). The disclosed antimicrobial and odor-controlling compositions are environmentally friendly and are as effective as, and in some cases more effective than, currently used heavy metal and nanomaterial formulations.

[0032] The antimicrobial and odor-controlling fiber coating compositions disclosed herein utilize benzoic acid as the primary antimicrobial and odor-controlling component. When applied to fibers by heat fixing and curing methods at high temperatures, the compositions described herein exhibit better thermal stability and sustained antimicrobial and odor-controlling properties compared to untreated fibers (fiber materials without the composition applied).

[0033] Benzoic acid is generally difficult to incorporate into and / or coat onto fibers / textile materials because it sublimes and partially decomposes at high temperatures during heat fixation. Therefore, when applying it to fibers / textile materials by padding and exhaustion methods, the final heat fixation / curing temperature should not exceed 130°C. However, the typical heat fixation temperature for polyester is 130°C to 170°C. Therefore, when a low curing temperature is required, the use of benzoic acid on textile materials such as polyester is limited. For this reason, to utilize benzoic acid in a fiber coating composition, it is necessary to use a low temperature and / or to use additional components that prevent the sublimation or decomposition of benzoic acid.

[0034] The first antibacterial and / or deodorizing fiber coating composition utilizes benzoic acid as the main antibacterial and odor-controlling component and terephthalic acid as a crosslinking agent. This composition prevents the sublimation and / or decomposition of benzoic acid by forming a permanent bond between the fiber and benzoic acid using terephthalic acid anchors. Terephthalic acid improves the thermal stability of benzoic acid, as well as its performance and wash durability, by binding benzoic acid to the fiber through crosslinking or covalent bonding.

[0035] Since benzoic acid is practically insoluble in water and terephthalic acid is insoluble in water, the first antimicrobial and / or deodorizing fiber coating composition may be a solid composition at ambient temperature. In a water-based coating process, it may be necessary to heat the first antimicrobial and odor control composition and / or add a dispersant to facilitate application to the fiber material. Examples of dispersants include, but are not limited to, fatty amines, alkylnaphthalene sulfonates, and more preferably ethoxylate alcohols. Ethoxylate alcohols are preferred because they are stable under acidic conditions for the first antimicrobial and / or deodorizing fiber coating composition. In certain embodiments, the dispersant is present in an amount of 0.1% to 2% by weight based on the total weight of the composition.

[0036] In the first fiber coating composition, the applicable weight ratio of benzoic acid to terephthalic acid is 2:1 to 8:1, where any endpoint within this range may be the endpoint of another range, more preferably 3:1 to 7:1, and most preferably 4:1 to 6:1. Even if the ratio deviates from this, antibacterial and odor-controlling effects may be observed if properly applied, but thermal stability and / or wash durability may be reduced. Furthermore, if the amount of benzoic acid is too low, the antibacterial effect of the composition will be reduced.

[0037] The first antibacterial and / or deodorizing fiber coating composition may be solid at ambient temperature. In the solid first antibacterial and / or deodorizing fiber coating composition, benzoic acid may be present in an amount of 65% to 90% by weight of the composition, and any endpoint within this range may be the endpoint of another range, such as 70% to 85% by weight, 75% to 85% by weight, and 75% to 80% by weight. In certain embodiments, benzoic acid is a benzoate such as sodium benzoate.

[0038] In a solid first antimicrobial and / or deodorizing fiber coating composition, terephthalic acid may be present in an amount of 10% to 35% by weight of the total weight of the composition, any endpoint within this range may be the endpoint of another range, which may include, for example, 15% to 20% by weight, 15% to 30% by weight, and 20% to 25% by weight.

[0039] The first antibacterial and / or deodorizing fiber coating composition may be a liquid or liquid dispersion at ambient temperature. The first antibacterial and / or deodorizing fiber coating composition may contain 90% to 98% by weight of water. The first antibacterial and / or deodorizing fiber coating composition may further contain 0.1% to 2% by weight of a dispersant to promote the dissolution of benzoic acid and / or terephthalic acid. Benzoic acid may be present in the first antibacterial and / or deodorizing fiber coating composition at an amount of 1.3% to 9% by weight of the composition, and any endpoint within this range may be the endpoint of another range, such as 1.5% to 8.5% by weight, 2% to 7% by weight, and 3% to 5% by weight. In certain embodiments, benzoic acid is a benzoate such as sodium benzoate. Terephthalic acid may be present in the first antibacterial and / or deodorizing fiber coating composition in an amount of 0.2% to 3.5% by weight of the total weight of the composition, any endpoint within this range may be the endpoint of another range, which may include, for example, 0.3% to 2.0% by weight, 0.5% to 1.5% by weight, and 0.75% to 1.3% by weight.

[0040] The second antibacterial and / or deodorizing fiber coating composition also utilizes benzoic acid as the main antibacterial and odor-controlling component, and also utilizes quatsilane. Quatsilane is also known for its antibacterial properties, but in this example, it is used as a solubilizer and stabilizer to retain benzoic acid in solution and make it suitable for the milling process. The second antibacterial and / or deodorizing fiber coating composition imparts not only antibacterial and odor-controlling properties to the treated textile product, but also water repellency. Organic solvents such as methanol, isopropyl alcohol, and acetone can also dissolve benzoic acid. However, in water-based fiber wet processes, benzoic acid recrystallizes and becomes solid again, resulting in uneven treatment of the fibers. Therefore, organic solvents alone are insufficient to stabilize benzoic acid. The second antibacterial and / or deodorizing fiber coating composition prevents the sublimation and / or decomposition of benzoic acid by forming a layer or coating on the surface that is covalently bonded to the polyester surface, trapping the benzoic acid within the coating.

[0041] In the second antibacterial and / or deodorizing fiber coating composition, the weight ratio of benzoic acid to quatsilane may be 2:5 to 1:4, and any endpoint within this range may be an endpoint within another range. Even if the ratio deviates from this, antibacterial and odor control effects may be observed if properly applied, but thermal stability, solubility, and / or wash durability may be reduced.

[0042] In the second antibacterial and / or deodorizing fiber coating composition, benzoic acid may be present in an amount of 20% to 30% by weight of the total weight of the composition, and any endpoint within this range may be the endpoint of another range, which may include 22% to 26% by weight, 23% to 28% by weight, 24% to 26% by weight, 22% to 24% by weight, and 23% to 25% by weight. In certain embodiments, benzoic acid is a benzoate such as sodium benzoate.

[0043] In the second antibacterial and / or deodorizing fiber coating composition, quatsilane may be present in an amount of 70% to 80% by weight of the total weight of the composition, and any endpoint within this range may be the endpoint of another range, which may include 73% to 78% by weight, 75% to 80% by weight, 75% to 78% by weight, and 72% to 78% by weight. The quatsilane may be 3-(trimethoxysilyl)propyldimethyloctadecylammonium salt, chloropropyltrimethoxysilane, methanol, octadecyldimethylamine, or a combination thereof. In certain embodiments, the quatsilane may be a mixture of 3-(trimethoxysilyl)propyldimethyloctadecylammonium salt, chloropropyltrimethoxysilane, methanol, and octadecyldimethylamine. In certain embodiments, quatsilane may comprise 74.9% to 69.1% by weight of 3-(trimethoxysilyl)propyldimethyloctadecylammonium salt, 16% by weight of chloropropyltrimethoxysilane, 10% to 19.5% by weight of methanol, and 2% by weight of octadecyldimethylamine. Although quatsilane itself is considered an antimicrobial agent, benzoic acid is the main antimicrobial and odor-controlling component in this composition.

[0044] The second antibacterial and / or deodorizing fiber coating composition may contain 80% to 95% by weight of water. In the second antibacterial and / or deodorizing fiber coating composition, benzoic acid may be present in an amount of 1% to 6% by weight of the composition, and any endpoint within this range may be the endpoint of another range, such as 1.2% to 5.6% by weight, 1.5% to 5% by weight, and 2% to 4% by weight. In certain embodiments, benzoic acid is a benzoate such as sodium benzoate. In the second antibacterial and / or deodorizing fiber coating composition, quatsilane may be present in an amount of 3.5% to 16% by weight of the total weight of the composition, and any endpoint within this range may be the endpoint of another range, such as 3.7% to 5.6% by weight, 4% to 14% by weight, and 4.3% to 13% by weight.

[0045] (Method for applying antibacterial and odor-controlling compositions) As further described and shown in the examples, the antimicrobial and / or deodorizing fiber coating composition may be applied (permanently) to the desired fiber material during the application process. The antimicrobial and / or deodorizing fiber coating composition may be applied to the desired fiber by exhaustion. In addition to or instead of this, the antimicrobial and / or deodorizing fiber coating composition may be applied to the desired fiber by padding. The application methods described herein allow for a uniform or even coating of the composition on the fiber, so that there is no discoloration or change in surface texture of the fiber after application, and the fiber is given consistent antimicrobial and deodorizing properties.

[0046] For example, with respect to the first antimicrobial and / or deodorizing fiber coating composition, when the padding method is used, a pad bath is prepared by mixing the first antimicrobial and odor control composition with water, and the concentration of the first antimicrobial and / or odor control composition in the water is approximately 2-10%. In certain embodiments, heat is used to dissolve the first antimicrobial and / or deodorizing fiber coating composition. In addition to or instead of this, a dispersant may be used to promote the dissolution of the first antimicrobial and / or deodorizing fiber coating composition. The dispersant may be added to the composition during preparation, or it may be used during application. The dispersant may be added at a concentration of 0.1% to 2% by weight based on the total weight of the composition. After padding the desired fiber material into a pad bath, curing / drying is performed in a tenter frame or dryer at a temperature of 110°C to 170°C for a minimum of 45 seconds to a maximum of 5 minutes, resulting in a dried fiber material that resists microbial growth on the fibers and controls odor for a long period of time (e.g., 25 wash cycles, 50 wash cycles, several months, or up to one year).

[0047] For example, when exhaustion is used for a first antimicrobial and / or deodorizing fiber coating composition, an exhaustion bath is prepared by mixing the first antimicrobial and / or deodorizing fiber coating composition with water, and the concentration of the composition in the water is approximately 2-10%. In certain embodiments, heat is used to dissolve the first antimicrobial and / or deodorizing fiber coating composition. In addition to or instead of this, a dispersant may be used to promote the dissolution of the first antimicrobial and / or deodorizing fiber coating composition. Exhaustion may be carried out in a beaker-type dyeing machine (e.g., Werner Mathis's Lobomat BFA-24) containing the desired fiber material. Exhaustion conditions may include a bath ratio (ratio of coating bath to fiber material) of 10:1, an exhaustion temperature of 110°C to 140°C, and a residence time at the exhaustion temperature of 20 to 50 minutes. The fibers and liquid medium are then cooled to a temperature of 40°C to 70°C. After absorption, the treated fiber material is washed and then dried in a dryer (optionally an infrared dryer) at a temperature of room temperature (approximately 20°C) to 190°C for at least 45 seconds to a maximum of overnight, thereby obtaining a dried fiber material that resists microbial growth on the fibers and controls odor for a long period of time (e.g., 25 wash cycles, 50 wash cycles, several months, or up to one year).

[0048] When the first antibacterial and / or deodorizing fiber coating composition is applied to a fiber, an antibacterial and deodorizing fiber material is obtained, in which benzoic acid forms the outermost surface of the antibacterial and deodorizing fiber material, and terephthalic acid forms an intermediate layer between the benzoic acid and the surface of the fiber material. This application method not only creates covalent bonds between terephthalic acid and the fiber chain, but also creates covalent bonds between terephthalic acid and benzoic acid.

[0049] For example, with respect to a second antimicrobial and / or deodorizing fiber coating composition, if a padding method is used, a pad bath is prepared by mixing the second fiber coating composition with water. The pad bath contains approximately 5-20% of the second antimicrobial and / or deodorizing fiber coating composition. The desired fiber material is padded into the pad bath 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 to a maximum of 5 minutes to obtain a dry fiber material that resists microbial growth on the fiber and controls odor for a long period of time (e.g., 25 wash cycles, 50 wash cycles, several months, or up to one year).

[0050] For example, when the exhaustion method is used for a second antimicrobial and / or deodorizing fiber coating composition, an exhaustion bath is prepared by mixing the second antimicrobial and / or deodorizing fiber coating composition with water. The exhaustion bath contains approximately 5-20% of the second fiber coating composition. Exhaustion may be carried out in a beaker-type dyeing machine (e.g., Werner Mathis's Lobomat BFA-24) containing the desired fiber material. Exhaustion conditions may include a bath ratio (ratio of coating bath to fiber material) of 10:1, an exhaustion temperature of 110°C to 140°C, and a residence time at the exhaustion temperature of 20-50 minutes. After that, the fiber and liquid medium are cooled to a temperature of 40°C to 70°C. After absorption, the treated fiber material is washed and then dried in a dryer (optionally an infrared dryer) at a temperature of room temperature (approximately 20°C) to 190°C for at least 45 seconds to a maximum of overnight, thereby obtaining a dried fiber material that resists microbial growth on the fibers and controls odor for a long period of time (e.g., 25 wash cycles, 50 wash cycles, several months, or up to one year).

[0051] (Fiber material with antibacterial and odor-controlling properties) This specification also discloses textile materials coated with any of the antimicrobial and / or deodorizing textile coating compositions described above. Textile materials coated with the first antimicrobial and / or deodorizing textile coating composition or the second antimicrobial and / or deodorizing textile coating composition prevent the growth of microorganisms over a longer period of time and also prevent odors caused by microorganisms, compared to textile materials not treated with the antimicrobial and / or odor control composition.

[0052] In certain embodiments, the textile material is coated with a first antimicrobial and / or deodorizing textile coating composition. In this embodiment, the first antimicrobial and / or deodorizing textile coating composition is coated at a concentration of 2% to 10% by weight of fabric (owf), more preferably 4% to 8% by owf, and most preferably 5% to 7% by owf. In this embodiment, the dried textile material treated with the first antimicrobial and / or deodorizing textile coating composition is coated with benzoic acid at a concentration of 1.3% to 9.0% by owf, more preferably 1.8% to 6.7% by owf, and most preferably 4.5% to 5.2% by owf, and terephthalic acid at a concentration of 0.2% to 3.5% by owf, more preferably 0.3% to 2.0% by owf, more preferably 0.7% to 1.2% by owf, and most preferably 0.7% to 1.1% by owf.

[0053] In certain embodiments, a dry fiber material is coated with a second antimicrobial and / or deodorizing fiber coating composition. The second antimicrobial and / or deodorizing fiber coating composition is coated at a concentration of 5% to 20% owf, more preferably 7% to 15% owf, and most preferably 8% to 10% owf. In this embodiment, the dry fiber material treated with the second antimicrobial and / or deodorizing fiber coating composition is coated with benzoic acid at a concentration of 1% to 6% owf, 1.2% to 5.6% owf, more preferably 1.4% to 4% owf, and most preferably 2.0% to 2.5% owf, and quatsilane at a concentration of 3.5% to 16% owf, 3.7% to 15.6% owf, more preferably 4% to 14.4% owf, and most preferably 6% to 8% owf.

[0054] Considering the concentrations and ratios described above, the fibrous material and / or the composition applied to the fibrous material reduce microbial growth by a log-3 reduction or more, more preferably a log-3.5 reduction or more, and most preferably a log-4.0 reduction or more over a long period of time.

[0055] In preferred embodiments, the fibrous materials disclosed herein, including fibrous materials, are either woven or nonwoven fibrous materials. In preferred embodiments, the fibrous material and / or fibrous material is a knitted / woven fabric containing polyester, nylon, rayon, cotton, or any combination thereof. In particular embodiments, the fabric weight of the fibrous material / dry fibrous material is 20 to 400 gsm (grams / square meter). It should be understood that the greater the fabric weight, the more of the above-mentioned composition it absorbs (e.g., during and after padding, and / or during and after exhaustion), thus allowing for a fibrous material with a long-lasting odor control / odor capture effect.

[0056] (Examples) As a first comparative example, benzoic acid was applied to polyester at 6% owf using exhaustion and cured at 170°C. The antimicrobial fiber test AATCC™ 100 was performed to measure the logarithmic reduction of Klebsiella pneumoniae before washing and after 25 washes. The AATCC™ 100 data are shown in Table 1 below. Benzoic acid showed little to no antimicrobial activity before washing, and no antimicrobial activity after washing. This is due to the thermal instability of benzoic acid.

[0057] [Table 1]

[0058] A second comparative example was evaluated. The composition of the second comparative example contains a quatsilane mixture that does not contain benzoic acid. The composition of the second comparative example comprises 72% by weight of 3-(trimethoxysilyl)propyldimethyloctadecylammonium salt, 16% by weight of chloropropyltrimethoxysilane, and 2% by weight of octadecyldimethylamine in methanol. Using exhaustion, the composition of the second comparative example was applied to polyester at 9% owf and cured at 170°C. The antimicrobial fiber test AATCC™ 100 was performed to measure the logarithmic reduction of Klebsiella pneumoniae and Staphylococcus aureus before washing and after 25 washes. The AATCC™ 100 data are shown in Table 2 below. When benzoic acid is not included in the composition, no logarithmic reduction in the growth of Klebsiella pneumoniae is observed. Furthermore, when benzoic acid is not included in the composition, the composition does not have wash durability. The logarithmic reduction in the growth of Staphylococcus aureus almost disappears after 25 washes at home.

[0059] [Table 2]

[0060] A first antibacterial and / or deodorizing fiber coating composition was prepared by mixing 83.3% by weight of benzoic acid and 16.75% by weight of terephthalic acid. The first antibacterial and / or deodorizing fiber coating composition was dissolved in water and applied to polyester with an exhaustion rate of 6% owf, and cured at 170°C. The antibacterial fiber test AATCC™ 100 was performed to measure the logarithmic reduction of Klebsiella pneumoniae and Staphylococcus aureus before washing and after 25 washes at home. The AATCC™ 100 data are shown in Table 3 below. When benzoic acid is combined with terephthalic acid, terephthalic acid binds / crosslinks benzoic acid with the polyester fibers of the fiber material, thereby improving the thermal stability and persistence of benzoic acid.

[0061] [Table 3]

[0062] A second antibacterial and / or deodorizing fiber coating composition was prepared by mixing 25% by weight of benzoic acid with 75% by weight of quatsilane (containing 72% by weight of 3-(trimethoxysilyl)propyldimethyloctadecylammonium salt, 16% by weight of chloropropyltrimethoxysilane, and 2% by weight of octadecyldimethylamine in methanol). The second antibacterial and / or deodorizing fiber coating composition was dissolved in water, applied with padding at an owf of 9%, and cured at 170°C. The antibacterial fiber test AATCC™ 100 was performed to measure the logarithmic reduction of Klebsiella pneumoniae and Staphylococcus aureus before washing, after 25 washes, and after 50 washes. The AATCC™ 100 data are shown in Table 4 below. When benzoic acid was combined with quatsilane, an improvement in the reduction of bacterial growth on the fiber was observed compared to the comparative example described above. Furthermore, the inclusion of quatsilane ensures that the antibacterial effect lasts for 25 and 50 washes at home. Quatsilane stabilizes benzoic acid, and when cured at high temperatures, it forms a polymer structure that captures benzoic acid and prevents sublimation. Quatsilane itself also possesses antibacterial properties. However, due to its chemical properties, quatsilane exhibits antibacterial performance only when using the ASTM E2149 test method, which involves salt-methanol washing after accelerated washing. Therefore, in this formulation, benzoic acid is the main antibacterial component, and quatsilane is merely a solubilizer. The performance of the treated fabric can be measured using any of the common antibacterial test methods, including (but not limited to) AATCC™ 100, ISO 20743, and JIS L 1902. The treated fabric may also be washed by normal home washing without salt-methanol washing. When the water repellency of fibers treated with a 9% second antimicrobial composition using owf was measured using AATCC™ 22, the score was 75 compared to a score of 0 for untreated fibers.
