[0018] The present invention will be described in detail below with reference to the embodiments and drawings. These embodiments are presented merely as examples to explain the invention more specifically, and it will be obvious to those skilled in the art that the scope of the invention is not limited by these embodiments.

[0019] Furthermore, unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by those skilled in the art to which the present invention pertains, and in the event of a conflict, the description in this specification, including the definitions, shall prevail.

[0020] In order to clearly explain the proposed invention in the drawings, parts unrelated to the explanation have been omitted, and similar parts throughout the specification have been given similar reference numerals. Furthermore, when a part is described as "comprising" a certain component, this means that, unless specifically stated otherwise, it does not exclude other components but may include additional components.

[0022] The scratch-resistant pet fabric of the present invention is characterized by being woven with weft yarns including Chanel yarns and flocking yarns; and warp yarns including high-strength yarns.

[0023] The present invention is characterized by using high-strength yarn as the warp for scratch resistance, and using Chanel yarn and flocking yarn as the weft to create an uneven shape between the fabric core and the surface and to provide a sufficient spatial gap.

[0024] Chanel yarn is a type of decorative yarn used for various purposes, such as towels, bath products, and car seat covers. It can be manufactured by twisting multiple core yarns together and inserting and fixing the auxiliary yarn between the core yarns, or by weaving a fabric in which the warp yarn is used as the core yarn and the weft yarn is used as the wing yarn, and then cutting the wing yarn in the warp direction.

[0025] The Chanel yarn used in the present invention is manufactured by 2 to 3 PET (Polyethylene Terephthalate) (300D) core yarns that intersect each other in succession and a plurality of low-melting point polyester fibers inserted perpendicularly into the space created by the intersecting core yarns, thereby not only creating sufficient irregularities but also minimizing shedding as the low-melting point fibers fuse to the core yarns. At this time, it is preferable that the pile length resulting from the fibers be 0.9 to 1.5 mm (0.5 to 1 D).

[0026] In addition, the flocking yarn is formed by applying an adhesive to the surface of a core, implanting short fibers, and drying them. The flocking yarn used in the present invention is preferably composed of a polyamide (300D) core and short fibers evenly implanted on the surface of the core with a pile length of 0.7 to 1.7 mm (0.5 to 1D).

[0027] At this time, it is preferable that the Chanel yarn and flocking yarn have a final thickness of 1,200 to 3,000 D after processing, and the ratio of the Chanel yarn and flocking yarn can be mixed in various ways according to the purpose and use, and in one embodiment, they can be used in a 1:1 ratio.

[0028] Meanwhile, the high-strength warp yarn used together with the weft yarn forming the geometric structure above serves to reinforce the strength of the fabric and is a fiber having a tensile strength of 20 g / d or more, and preferably comprises a polymer of any one of aramid, ultra-high molecular weight polyethylene (UHMWPE), polyphenylenebenzobisoxazole (PBO), and polyamide (PA66).

[0029] In addition, the high-strength yarn may be manufactured through the steps of: preparing a slurry of a polymer of any one of aramid, ultra-high molecular weight polyethylene (UHMWPE), polyphenylenebenzobisoxazole (PBO), and polyamide (PA66); dispersing silicon microparticles in the slurry; and spinning the slurry in which silicon microparticles are dispersed to produce the high-strength yarn; and the high-strength yarn may also be manufactured by various other commercially available methods. In this case, silicon microparticles adsorbed with various functional components may be used.

[0030] The above silicon microparticles include both silicon and silicon oxide forms, and it is preferable that the average particle size be 1 to 500 nm to exhibit an antiviral effect. If the average particle size is less than 1 nm, the adsorption effect may be negligible, and if it exceeds 500 nm, dispersibility and stability may be reduced. In addition, the content of the above silicon microparticles may be added in an amount of 0.1 to 1 part by weight based on 100 parts by weight of the slurry.

[0031] It is preferable that the above silicon microparticles be in a form that adsorbs antibacterial components to add antibacterial properties to the fabric, and preferably, it is preferable to use silicon microparticles that are loaded with an antibacterial composition and then dried, or silicon microparticles that are sprayed with an antibacterial composition on the surface of the silicon microparticles and then dried.

[0032] The above antimicrobial composition may include various antimicrobial components, but as a preferred embodiment, 0.1 to 1 part by weight of silver may be added to 100 parts by weight of distilled water.

[0033] The silver mentioned above has antibacterial, deodorizing, negative ion, and far-infrared emitting effects, and it is common to use high-purity silver that has been nano-sized. The content of the silver is preferably 0.1 to 1 weight part; if it is smaller than this, it may be difficult to fully exhibit the functional effects of the silver, and if it is larger, the overall miscibility may decrease.

[0034] Meanwhile, when manufacturing the above silver nanoparticles, surfactants or various additives must be used to suppress the aggregation of silver particles. However, in such cases, it may be difficult to fully exert the functional effects of silver, or it may take on a distinctive color, and harmful effects may occur due to the additives.

[0035] Accordingly, the present invention can improve stability by using a complex prepared by reacting a salt containing silver ions with a salt containing sulfate-based anions. At this time, various materials capable of forming a complex may be used for the salt containing silver ions and the sulfate-based anions, but preferably, the salt containing silver ions may be silver nitrate or silver acetate, and the salt containing sulfate-based anions may be any one selected from sodium sulfate, sodium sulfite, potassium sulfate, potassium sulfite, ammonium sulfate, and ammonium sulfite, or a mixture thereof.

[0036] When the above silver ions are used in the form of a silver-sulfate complex, it is preferable that the content of the silver-sulfate complex be 0.1 to 2 parts by weight.

[0037] Meanwhile, the above slurry may additionally include copper microparticles in addition to silicon microparticles, and the content of the copper microparticles may be added in an amount of 0.1 to 1 part by weight based on 100 parts by weight of the slurry. It is preferable to use copper microparticles that are polymer-coated to improve dispersibility within the slurry and minimize the possibility of deterioration in air, thereby ensuring that the antibacterial effect is continuously maintained. Various coating polymers may be used, but it is preferably coated with fatty acids and ester compounds. Through this coating, oxidation of the microparticle surface caused by increased surface activity of the copper microparticles is prevented, and the aggregation of the microparticles is suppressed, allowing excellent antiviral properties to be exhibited over a long period.

[0038] Specifically, the fatty acid may be myristic acid, stearic acid, oleic acid, palmitic acid, n-decanoic acid, paratolic acid, succinic acid, malonic acid, tartaric acid, malic acid, glutaric acid, adipic acid, acetic acid, or a mixture thereof, and in particular, a higher fatty acid having 10 to 22 carbon atoms, among which stearic acid is preferred.

[0039] In addition, the ester compound coating the surface of the copper microparticles may be an ester compound of the fatty acid and an ester compound of the polyol, and preferably, diethylene glycol distearate, ethylene glycol distearate, propylene glycol distearate, or a mixture thereof may be used. The polyol may be ethylene glycol, diethylene glycol, triethylene glycol, polyethylene glycol, glycerin, etc.

[0040] The above polymer-coated copper microparticles can be prepared by adding copper stearate to a polyol and heating and mixing it at a temperature below the thermal decomposition initiation temperature of copper stearate to prepare a dispersion in which copper microparticles coated with copper stearate are dispersed, mixing the dispersion with a low-boiling point solvent that has been prepared by mixing a dispersant and an ester compound, and then separating the polyol and the low-boiling point solvent into two phases to separate the low-boiling point solvent containing copper microparticles coated with a fatty acid and an ester compound.

[0041] Alternatively, the above polymer-coated copper microparticles can be prepared by adding a copper compound of copper acetate, copper chloride, or copper bromide to a polyol and heating and mixing it to prepare a dispersion in which copper microparticles coated with fatty acid are dispersed, and then mixing the dispersion with a low-boiling point solvent prepared by mixing a dispersant and an ester compound, and then separating the polyol and the low-boiling point solvent into two phases to separate the low-boiling point solvent containing copper microparticles coated with fatty acid and an ester compound.

[0042] The above low-boiling point solvent can be volatilized to finally obtain copper fine particles, and the above low-boiling point solvent can be any one of butyl acetate, ethyl acetate, or methyl isobutyl ketone.

[0043] When weaving as described above, the weft yarn has a diameter of about 0.6mm to 0.7mm and the warp yarn has a diameter of about 0.1 to 0.2mm, creating an irregularity of about 0.4 to 0.6mm, and pile yarn is formed on the surface, so the effect of scratches is reduced, and even if scratches occur, durability is maintained due to the strength of the ultra-strong yarn.

[0044] Meanwhile, it is preferable to spray a surface coating composition on the surface of the manufactured fabric to further enhance scratch resistance, and in one embodiment, the surface coating composition preferably comprises 10 to 30 parts by weight of silicone oil, 1 to 10 parts by weight of wax, and 0.1 to 10 parts by weight of a crosslinking agent based on 100 parts by weight of acrylic resin.

[0045] The above acrylic resin can be any general resin used in fiber coating agents. The above silicone oil can be any generally commercially available silicone oil, but specifically, dimethyl silicone oil, methylphenol silicone oil, methyl hydrogen silicone oil, amino-modified silicone oil, epoxy-modified silicone oil, carboxyl-modified silicone oil, carbinol-modified silicone oil, polyether-modified silicone oil, alkyl-modified silicone oil, fluorine-modified silicone oil, etc., may be used.

[0046] Meanwhile, the above silicone oil may be used alone, but it may also be used in a form coated on the surface of copper microparticles to enhance antibacterial properties. Furthermore, the silicone coating prevents oxidation of the surface of the copper microparticles and inhibits the aggregation of the microparticles, thereby enabling the copper microparticles to exhibit antiviral properties over a long period.

[0047] In addition, the silicone oil may be used in a form coated on glass bubbles to achieve moisture resistance and low thermal conductivity and to improve dispersibility within the composition. Glass bubbles are hollow fine powders that have good flowability, allow for lightweighting, are chemically stable, and possess moisture resistance.

[0048] More preferably, the silicone oil coated on the surface of the copper microparticles and the silicone oil coated on the glass bubbles can be used in a mixed form at a weight ratio of 1:9 to 9:1.

[0049] The viscosity of the silicone oil is not particularly limited, but it is preferable to use one with a viscosity of 20 to 500 cSt. The method of surface treatment with silicone oil is not particularly limited, and a wet method may be used in which silicone oil is dissolved in a solvent such as toluene, copper microparticles or glass bubbles are dispersed in the solvent, and the solvent is evaporated to attach silicone oil to the surface of the copper microparticles or glass bubbles, or a dry method may be used in which silicone oil is sprayed onto copper microparticles or glass bubbles to attach silicone oil to the surface of the glass bubbles and a predetermined heat treatment is performed.

[0050] Various commercially available crosslinking agents may be used as the above crosslinking agent, for example, melamine resin, glyoxal resin, or compounds having isocyanate groups may be used.

[0051] In this way, the fabric dried after spraying the surface coating composition not only has improved scratch resistance and durability but also possesses antibacterial properties, making it optimized for use as a fabric for pets.

[0052] Although the present invention has been described in relation to preferred embodiments as mentioned above, the technical concept of the invention is not limited thereto and can be modified and implemented in various ways by those skilled in the art.
