Description

The present invention relates to textured textiles with both antistatic and antiviral wash durability.

Antiviral processing on textile products is expected to expand its applications in the future, such as white coats for hospitals and nursing homes, and work clothes for food factories. A method for evaluating antiviral properties on textile products based on ISO18184 has been established, and a mark certification system for antiviral processed textile products has been established by the Textile Evaluation Technology Council.

However, for textile products, especially white coats and work clothes that require repeated washing, and linen products such as hospital sheets and curtains, improving washing durability against antiviral performance has become an issue.

For example, Patent Literatures 1 and 2 describe an antiviral treatment in which the antiviral compound is a quaternary ammonium halide compound on a resin molded product or fiber product having an antiviral compound fixed on at least the surface. However, the quaternary ammonium salts described herein are those containing only one chain of linear alkyl groups having 10 or more carbon atoms, or those containing two chains of linear alkyl groups having up to 9 carbon atoms at most. Although quaternary ammonium salts have been disclosed, the problem with these quaternary ammonium salts is that they are highly soluble in water and have low durability in washing. Furthermore, didecyldimethylammonium chloride disclosed in Patent Documents 1 and 2 is designated as a deleterious substance, so the amount used in textile products is limited, and while ensuring safety, washing durability of about 10 washings at most. However, the actual situation is that only high durability has been obtained, and higher washing durability has been demanded. In addition, white coats and work clothes are required not to be antistatic, and conventional quaternary ammonium salts are highly water-soluble, so antistatic (antistatic) washing durability is also required. The reality was that it was low.

However, for textile products, especially white coats and work clothes that require repeated washing, and linen products such as hospital sheets and curtains, improving washing durability against antibacterial performance and antiviral performance has become an issue.

WO2016-009928A1 Japanese Patent No. 5571577

The present invention was invented in view of the current state of the prior art described above, and its object is to provide a textile product that is safe, has excellent washing durability, and satisfies both antiviral and antistatic properties. A further object of the present invention is to provide an antibacterial/antiviral processed textile product that is suitable for use in clothing applications, etc., and has excellent durability against repeated washing and wearing even in high-temperature industrial washing.

As a result of intensive studies to achieve the above objects, the present inventors have found that a quaternary ammonium salt containing a plurality of specific long-chain alkyl groups, especially a cathode composed of atoms with high electronegativity such as chloride ion and bromide ion I focused on quaternary ammonium salts, which are salts formed by ions, particularly halide ions and quaternary ammonium cations (cations). We have found that these quaternary ammonium salts enable the development of products that possess not only excellent antibacterial and antiviral properties, but also antistatic wash durability.

The present invention has been completed based on the above findings, and has the following configurations (1) to (5).
(1) An antistatic/antiviral textile product containing 0.01 to 10.0% by weight of at least one quaternary ammonium salt selected from the group of [Chemical 1]. However, in [Formula 1], m and n are integers of 0 to 5, p and q are integers of 15 to 22, and X- is a halide ion.
(2) The textile product according to (1), containing at least one of polyester fiber, polyamide fiber, acrylic fiber, polypropylene fiber, and cellulose fiber in an amount of 60% by weight or more.
(3) The antiviral activity value Mv after 15 washings according to the “SEK mark textile product washing method: October 13, 2020 edition” issued by the Product Certification Department of the Textile Evaluation Technology Council is 3.0 The textile product according to (1) or (2) above, characterized in that the frictional electrification voltage after washing five times is 1500 V or less.
(4) The textile product according to any one of (1) to (3), wherein the fiber is a woven or knitted fabric made of multifilament drawn yarn and/or false twisted yarn, or a nonwoven fabric made of multifilament.
(5) The textile product according to any one of (1) to (3), wherein the fibers are staple fibers and are non-woven fabric, paper, batting or spun yarn having a single filament fineness of 0.01 to 15.0 decitex.

According to the present invention, it is possible to provide a textile product having excellent washing durability and antistatic and antiviral properties. It has the effect of reducing and inactivating viruses such as influenza virus and feline calicivirus, and also has unprecedented durable antistatic properties. It can be used for a wide range of applications including frequent washing.

FIG. 1 shows a group of quaternary ammonium salts [Chemical 1] used in the present invention.

In the textile product of the present invention, the compound that exerts antistatic and antiviral properties is a quaternary ammonium salt having two or more straight-chain alkyl groups with 16 or more carbon atoms. Specifically, it is at least one quaternary ammonium salt selected from the group of [Formula 1].
However, in [Formula 1], m and n are integers of 0 to 5, p and q are integers of 15 to 22, and X- is a halide ion.

The quaternary ammonium salt represented by the above [Chemical Formula 1] has two straight-chain alkyl groups with 16 or more carbon atoms, and the straight-chain alkyl groups with 16 or more prime numbers may be the same or different. However, it is preferable that the two linear alkyl groups having 16 or more carbon atoms are the same. This is because it is easy to obtain high antiviral properties. Although the reason for this is not clear, it is believed that the effect of denaturing proteins constituting viruses increases when long-chain alkyl groups of the same length are paired.
Examples of quaternary ammonium salts having two identical straight-chain alkyl groups of 16 or more carbon atoms are shown below. For example, distearyldimethylammonium chloride, dibehenyldimethylammonium chloride, diarachidyldimethylammonium chloride, dicetyldimethylammonium chloride, dihexadecyldimethylammonium chloride, distearyldimethylammonium methosulfate, distearyldi(isopropyl)ammonium chloride or di- and stearoyl(hydroxyethyl)methylammonium chloride. Among these, distearyldimethylammonium chloride, dibehenyldimethylammonium chloride and dicetyldimethylammonium chloride are more preferred. Incidentally, although chlorides are representatively exemplified above, other halides such as these bromides and methosulfate may be used. These may be used alone or in combination of two or more.

Among these quaternary ammonium salts having two identical straight-chain alkyl groups having 16 or more carbon atoms, distearyldimethylammonium chloride, dibehenyldimethylammonium chloride and dicetyldimethylammonium chloride having 18 or more carbon atoms are particularly , the residue is high when textile products are repeatedly washed, and the antistatic and antiviral washing resistance can be enhanced. The quaternary ammonium salt is often used for the purpose of softening agents such as cosmetics and hair conditioners and for antistatic purposes, but when applied to hydrophobic fibers such as polyester fibers under specific conditions, it may cause high washing. It has not been known to have durability or to exhibit antiviral properties.

Many quaternary ammonium salts cause mild skin irritation and strong irritation to mucous membranes, including eyes, when used excessively. Since it has two molecules and forms a synthetic bilayer structure, it is reported to have relatively low skin irritation (Suzuki Kazunari (2012) "Distearyldimethylammonium chloride" Cosmetic Ingredients Dictionary 2012, 500.) , There are no reports of serious skin irritation in the more than 30 years of use.

The amount of the quaternary ammonium salt used relative to the fiber weight is preferably 0.1 to 10.0%owf, more preferably 0.2 to 6.0%owf, and still more preferably 0.40 to 5.5%owf. %owf. If it is less than 0.1%, it becomes difficult to exhibit sufficient antiviral properties. On the other hand, if it is 10.0% owf or more, the antistatic properties and antiviral properties reach a peak, and the production cost becomes too high, and the textile products may be discolored.

By using the quaternary ammonium salt of the present invention, it is possible to impart antistatic properties with high washing durability to textile products. In addition, steartrimonium chloride and behentrimonium chloride may be used in combination.

The antibacterial/antiviral processed textile product of the present invention is an antibacterial/antiviral finishing agent consisting of a quaternary ammonium salt represented by the above formula [a] or a derivative thereof, and is used to post-process primary fiber products such as woven fabrics, knitted fabrics, and non-woven fabrics. Obtained by processing. As a post-processing method, a known method such as an exhaust method, a padding method, a spray method, a coating method and a printing method can be employed. For example, in the case of the exhaust method, it is possible to carry out dyeing in the same bath, or separate baths in an optional step after dyeing. In the case of the padding method, after dyeing, a predetermined amount of chemical solution is picked up by a mangle padder or the like on the fabric, and then heat-treated. The heat treatment can be carried out by known methods such as pad dry method, pad dry cure method, pad steam cure method and the like. Also, the above methods can be used in combination, if necessary.

The temperature conditions for the post-processing treatment vary depending on the type of fiber used. For example, in the case of the exhaustion method, it can be appropriately set in the range of 70 to 135°C with wet heat, more preferably in the range of 90 to 130°C with wet heat. In the padding method, the pad (dry) curing method can be exemplified by a dry temperature range of 100 to 130°C and a curing temperature range of 140 to 190°C. A more preferable curing temperature is 160° C. to 180° C. for 30 seconds to 2 minutes. The higher the curing temperature, the higher the residual rate of the quaternary ammonium salt after washing. It tends to decompose gradually and the active ingredients tend to decrease. In addition, excessive heat treatment adversely affects physical properties such as various fastnesses and causes yellowing, so it is desirable to avoid it.

In order to uniformly and stably process the quaternary ammonium salt of the present invention into fibers, it can be used in combination with a nonionic surfactant and a cationic surfactant solvent. Nonionic surfactants include polyoxyalkylene ethers, polyoxyalkylene alkyl ethers, polyoxyalkylene fatty acid esters, polyoxyalkylene fatty acid diesters, polyoxyalkylene resin acid esters, polyoxyalkylene (cured) castor oils, polyoxyalkylene alkylphenols, polyoxyalkylene alkylphenyl ethers, polyoxyalkylene phenyl ethers, polyoxyalkylene alkyl esters, polyoxyalkylene alkyl esters, sorbitan fatty acid esters, polyoxyalkylene sorbitan alkyl esters, polyoxyalkylene sorbitan fatty acid esters, polyoxyalkylene sorbit fatty acid esters, polyoxyalkylene glycerin fatty acid esters, polyglycerin alkyl ethers, polyglycerin fatty acid esters, sucrose fatty acid esters, fatty acid alkanolamides, alkyl glucosides, Polyoxyalkylene fatty acid bisphenyl ethers, polypropylene glycol, polyether-modified silicone, that is, polyoxyalkylene-modified diorganopolysiloxane, polyglyceryl-modified silicone, glyceryl-modified silicone, sugar-modified silicone, perfluoropolyether surfactant, poly Oxyethylene/polyoxypropylene block copolymers and alkyl polyoxyethylene/polyoxypropylene block copolymer ethers are exemplified. Among these, polyoxyethylene addition type nonionic surfactants such as polyoxyalkylene alkyl ethers and polyoxyalkylene fatty acid esters are preferably used.

The nonionic surfactant preferably has an HLB of 7-18. More preferably HLB 8-16, more preferably HLB 10-14. Specifically, polyoxyethylene sorbite fatty acid ester (HLB12.5), polyoxyethylene sorbitan fatty acid ester (HLB11), polyoxyethylene glycerin fatty acid ester, and the like are preferably used.

Examples of cationic surfactants include lauryltrimethylammonium chloride, myristyltrimethylammonium chloride, palmityltrimethylammonium chloride, stearyltrimethylammonium chloride, oleyltrimethylammonium chloride, cetyltrimethylammonium chloride, behenyltrimethylammonium chloride, coconut oil alkyltrimethyl Alkyl quaternary ammonium salts such as ammonium chloride, tallow alkyltrimethylammonium chloride, stearyltrimethylammonium bromide, coconut oil alkyltrimethylammonium bromide, cetyltrimethylammonium methosulfate, oleyldimethylethylammonium ethosulfate, octadecyldiethylmethylammonium sulfate; Polyoxyethylene) Lauryl Amino Ether Lactate, Stearyl Amino Ether Lactate, Di (Polyoxyethylene) Lauryl Methyl Amino Ether Dimethyl Phosphate, Di (Polyoxyethylene) Lauryl Ethyl Ammonium Ethosulfate, Di (Polyoxyethylene) Hydrogenated Tallow Alkyl (Polyoxyalkylene) alkylamino ether salts such as ethylamine ethosulfate, di(polyoxyethylene)laurylmethylammonium dimethylphosphate, di(polyoxyethylene)stearylamine lactate; N-(2-hydroxyethyl)-N,N - acylamidoalkyl quaternary ammonium salts such as dimethyl-N-stearoylamidopropylammonium nitrate, lanolin fatty acid amidopropylethyldimethylammonium ethosulfate, lauroylamidoethylmethyldiethylammonium methosulfate; dipalmitylpolyethenoxyethylammonium chloride; , alkylethenoxy quaternary ammonium salts such as distearylpolyethenoxymethylammonium chloride; benzyldimethyl{2-[2-(p-1,1,3,3-tetramethylbutylphenoxy)ethoxy]ethyl}ammonium benzethonium salts such as chloride; pyridinium salts such as cetylpyridinium chloride; imidazolinium salts such as oleyl hydroxyethyl imidazolinium ethosulfate and lauryl hydroxyethyl imidazolinium ethosulfate; N-cocoyl arginine ethyl ester pyrrolidone carboxylic acid acyl basic amino acid alkyl ester salts such as acid salts, N-lauroyl lysine ethyl ethyl ester chloride; primary amine salts such as laurylamine chloride, stearylamine bromide, hydrogenated beef tallow alkylamine chloride, rosinamine acetate; cetylmethylamine sulfate; secondary amine salts such as , laurylmethylamine chloride, dilaurylamine acetate, stearylethylamine bromide, laurylpropylamine acetate, dioctylamine chloride, octadecylethylamine hydroxide; dilaurylmethylamine sulfate, lauryldiethylamine chloride, laurylethyl tertiary amine salts such as methylamine bromide, diethanolstearylamidoethylamine trihydroxyethyl phosphate salt, stearylamidoethylethanolamine urea polycondensate acetate; fatty acid amide guanidinium salts; alkyls such as lauryltriethyleneglycol ammonium hydroxide and trialkylene glycol ammonium salts.

The organic solvent is not particularly limited as long as it is miscible with water. Examples include ethers such as ethers, and glycols such as propylene glycol, dipropylene glycol and tripropylene glycol. In addition, the ratio of water and the organic solvent is not particularly limited.

Furthermore, in order to improve washing durability, binders such as melamine formaldehyde resins, acrylic resins, urethane resins and silicone resins may be used in combination. When these resins are used together, simultaneous treatment or multistage treatment may be performed. In the case of multistage treatment, the order of chemical treatments is not limited.

The antibacterial/antiviral processed textile product of the present invention contains 60% by weight or more of at least one synthetic fiber selected from polyester fiber, polyamide fiber, acrylic fiber, polypropylene fiber, and polyurethane fiber, singly or in combination. Textile products are preferably made of polyester fibers. The blending ratio of these synthetic fibers in textile products is preferably 80% by weight or more, more preferably 90% by weight or more. If the content is less than the above range, the initial performance of antibacterial and antiviral properties is good, but the durability against repeated washing is insufficient, which is not preferable for clothing applications that require repeated washing. As the polyester fiber of the present invention, known fibers such as polyethylene terephthalate, polybutylene terephthalate, polytrimethylene terephthalate, and polyethylene naphthalate can be used. Of course, in addition to these homopolymer fibers, it is also possible to use a combination of a plurality of such fibers, and it is also possible to form a multi-layer laminated structure or a core-sheath structure fiber by a composite spinning method. Further, it may be a copolymer polyester or a blend polymer in which a polyester is used as a matrix and other polymers are kneaded.

Known fibers can be used as fibers that can be mixed at less than 20% in addition to the above synthetic fibers. For example, known fibers such as viscose rayon, cuprammonium rayon, and polynosic can be used for regenerated fibers, and cellulose acetate (triacetate, diacetate) and Promix can be used for semi-synthetic fibers. Natural fibers include cotton, hemp (flax, hemp, ramie, manila hemp, sisal hemp, etc.), wool, cashmere, mohair, alpaca, silk, kapok, kenaf, pineapple fiber, sugarcane fiber, hibiscus fiber, banana fiber, A known material such as bamboo fiber can be used. Moreover, the shape of these fibers may be either short fibers or long fibers, and the cross-sectional shape may be a circular cross section, a rectangular cross section, a multi-leaf cross section, a hollow cross section, or any other known cross section. Furthermore, not only short fibers and long fibers, but also spun yarns obtained by a long-short composite spinning method may be used, and there is no particular limitation.

In addition, the antistatic/antiviral fiber product of the present invention contains 60% by weight or more of at least one synthetic fiber selected from polyester fiber, polyamide fiber, acrylic fiber, polypropylene fiber, and polyurethane fiber, singly or in combination. These fibers are in the form of textile products composed of multifilament drawn yarn and/or false twisted yarn, or nonwoven fabrics composed of staple fibers, spun yarn, sheets such as paper, wadding, hard cotton, spun yarn, etc. is preferably When the fibers are multifilament drawn yarns and/or false twisted yarns, the fineness of single yarns is preferably 0.3 to 9.0 decitex. It is more preferably 0.5 to 8.0 decitex, still more preferably 1.0 to 5.0 decitex. When the fibers are staple fibers, the single yarn fineness is preferably 0.01 to 15.0 decitex. The above-mentioned single filament fineness does not have to be a single fineness, and the use of a combination of fibers having a plurality of finenesses is not limited at all. Ultrafine fibers with a single filament fineness below the above range have a large surface area and good initial antibacterial and antiviral performance, but may be easily removed by repeated wearing or washing, resulting in reduced durability. In addition, ultra-thick fibers with a single filament fineness exceeding the above range have a strong tingling sensation at the sewn part due to the large cross section of the fibers, giving strong skin irritation and making the textile product too hard. It becomes difficult to be desirable for clothing and respective uses.

The textile product of the present invention is characterized by having an antiviral activity value Mv of 3.0 or more after 15 washings. The quaternary ammonium salt used in the present invention has a relatively low solubility in water and a high affinity for hydrophobic fibers, particularly polyester, so that durability to washing can be improved. In a particularly preferred form, it is possible to achieve an antiviral activity value of 3.0 or more even after 30 washes.

Viruses are broadly classified into enveloped viruses and non-enveloped viruses. An envelope is a membranous structure found in some virus particles (virions) such as herpes simplex virus and influenza virus. It constitutes the outermost shell. The envelope consists mostly of lipids and can be easily destroyed by treatment with alcohol or organic solvents, so non-enveloped viruses are generally more difficult to inactivate than enveloped viruses. .

Examples of enveloped viruses include influenza virus, measles virus, rubella virus, AIDS virus, and herpes virus. Representative examples of non-enveloped viruses include norovirus, rotavirus, poliovirus, adenovirus, enterovirus, and the like. Quaternary ammonium salts tend to be less effective against non-enveloped viruses. excellent antiviral effect.

The textile product of the present invention exhibits excellent antistatic performance and antiviral performance with excellent durability to washing, and is less susceptible to changes in texture, discoloration, and physical properties of the fabric, so that it can be suitably used for hospital gowns and the like. Other uses include rental uniforms such as white coats for food, sheets, curtains, innerwear, shirts, school uniforms, gym clothes, and a wide range of other fields.

The textile product of the present invention can have a frictional electrification voltage of 1500 V or less after five washings. The quaternary ammonium salt used in the present invention has relatively low water solubility and Since it has a high affinity for polyester, it can improve durability to washing. In a particularly preferred form, the frictional electrification voltage can be maintained at 2000 V or less even after 10 washes.
