Description

GROOMING GOWN FOR PET GROOMING AND METHOD OF MANUFACTURING THE SAME { GROOMING GOWN FOR PET GROOMING }

The following examples relate to a grooming gown for pet grooming and a method for manufacturing the same.

Recently, as the number of people raising pets has increased and the number of people who treat their pets like family members or children has increased, the demand for items such as pet clothing and grooming products has increased rapidly.

Grooming gowns for pet grooming are also produced in various ways. Microorganisms can inhabit textile products due to improper use or storage, or they can inhabit and multiply using human secretions as a source of nutrition when in contact with the human body, causing bad odors in the product, contamination, discoloration, etc., which not only reduces the durability and fastness of the product, but can also be harmful to the health of humans who use these textile products.

In particular, cotton fabrics or cotton/polyester blended fabrics have been mainly used as materials for conventional sanitary and protective clothing, but the above conventional materials have very poor antibacterial properties and have been the main cause of infection. In addition, when cotton fabrics are used as materials for cosmetic and sanitary clothing, there is a problem of reduced comfort due to weight increase caused by sweating in addition to the problem of poor antibacterial properties.

The embodiments relate to a grooming gown for pet grooming and a method for manufacturing the same.

According to one embodiment, a grooming gown for pet grooming is manufactured using a mixed spun yarn made of a composite staple fiber of a sheath-core type in which a core component made of a polyester resin and a sheath component made of a polyester resin containing 1 to 6 wt% of titanium dioxide (TiO2) are compositely spun; and a staple fiber made of a natural fiber or a synthetic fiber.

A grooming gown for pet grooming is manufactured by (i) a process for manufacturing a sheath-core type composite filament by composite spinning of a core component composed of a polyester resin and a sheath component composed of a polyester resin containing 1 to 6 wt% of titanium dioxide (TiO2), and then manufacturing a composite staple fiber therefrom; (ii) a process for manufacturing a spun yarn by mixing the sheath-core type composite staple fiber and a staple fiber composed of a natural fiber or a synthetic fiber, and then manufacturing a fabric using the spun yarn; and (iii) a process for photodepositing metal nanoparticles having an average diameter of 1 to 5 nm on the surface of the fabric by immersing the fabric in a salt-type metal precursor solution and then irradiating it with ultraviolet rays for 4 to 60 seconds.

A grooming gown for pet grooming is a process for manufacturing a fabric using the spun yarn by mixing (ii) the sheath-core type composite staple fiber and the staple fiber composed of natural fiber or synthetic fiber; Next, the fabric is manufactured by further including a process of weight-loss treatment with an alkaline aqueous solution, and the staple fibers composed of the natural fibers or synthetic fibers are one or more staple fibers selected from the group consisting of cotton, hemp, wool, silk, polyester, polypropylene, rayon, aramid, polyethylene, polyvinyl alcohol, polyacrylonitrile, polyurethane, and polyamide fibers, and are manufactured by mixing and spinning the staple fibers, and the titanium dioxide nanopowder has a diameter of 15 to 100 nm and has a crystal phase of one of a form having an anatase phase with photoactivity and a form having a composite phase of anatase and rutile, and the metal nanoparticles are one or more metal nanoparticles selected from the group consisting of silver (Ag), platinum (Pt), gold (Au), copper (Cu), and the like.

The examples have excellent UV shielding, deodorizing, and antibacterial properties, and can effectively prevent the human body from bacteria and UV rays. They also do not deteriorate in performance after repeated washing and provide a texture similar to cotton fabric, and are therefore useful as cosmetic gowns, medical gowns, sanitary garments, and protective clothing.

Meanwhile, the effects according to the embodiments are not limited to those mentioned above, and other effects not mentioned can be clearly understood by a person having ordinary skill in the art from the description below.

The spun yarn of the grooming gown for pet grooming according to the present invention is a mixed spun yarn composed of (i) a core component composed of a polyester resin and a sheath component composed of a polyester resin containing 1 to 6 wt% of titanium dioxide (TiO2), a composite staple fiber of a sheath-core type, and (ii) staple fibers composed of natural fibers or synthetic fibers; and the fabric is a fabric that is a fabric or knitted fabric woven with the spun yarn, and the surface of the fabric is characterized by being photodeposited with metal nanoparticles having an average diameter of 1 to 5 nm. More specifically, the surface of the fabric is characterized by being photodeposited with metal nanoparticles having an average diameter of 1 to 5 nm, and having an antibacterial effect of 99.9% or higher against Staphylococcus aureus and Streptococcus pneumoniae measured by the KS K 0698 method even after 50 washes by the KS K 0430 method for measuring washing fastness. The above-mentioned sheath-core type composite staple fiber is a sheath-core type composite staple fiber which is compositely spun with a core component composed of a polyester resin and a sheath component composed of a polyester resin containing 1 to 6 wt% of titanium dioxide having an average diameter of 15 to 100 nm. Fig. 1 is a schematic diagram showing a cross-section of a sheath-core type composite staple fiber which is compositely spun with a core component composed of a polyester resin and a sheath component composed of a polyester resin containing titanium dioxide. According to Fig. 1, it can be seen that the core component composed of a polyester resin is surrounded by a polyester resin containing titanium dioxide. At this time, the core component of the composite staple fiber is composed of a polyester resin having an intrinsic viscosity (Ⅳ) of about 0.63, and the sheath component is composed of a component containing 1 to 6 wt% of titanium dioxide having an average diameter of 15 to 100 nm in a polyester resin having an intrinsic viscosity (Ⅳ) of about 0.63.

The single yarn fineness of the composite staple fiber used in the above mixed spinning is preferably 1 to 5 denier, the single yarn length is preferably 10 to 50 mm, and the fineness of the above mixed spun yarn is preferably 10 to 120 counts.

The staple fibers composed of the above natural fibers or synthetic fibers are one selected from the group consisting of cotton, hemp, wool, silk, polyester, polypropylene, rayon, aramid, polyethylene, polyvinyl alcohol, polyacrylonitrile, polyurethane, and polyamide fibers, or are yarns manufactured by mixing and spinning one or more staple fibers. When yarns are manufactured by mixing and spinning with natural fibers or synthetic fibers, the inherent properties and advantages of natural fibers and synthetic fibers can be exhibited, and in particular, since they can provide a feel similar to cotton fabric even after repeated washing, they are useful as fabrics for hospital clothing such as doctor's gowns.

In the present invention, the composition of the spun yarn may be T/C (polyester, cotton), T/R (polyester, rayon), and the blending ratio may be 10 to 90% polyester, 10 to 90% cotton, and rayon. In addition, the fineness may be one or more selected from a group composed in the range of 1 to 5 denier.

The sheath-core type composite staple fibers and natural fibers are mixed and spun to form yarns that make up the fabric.

When metal nanoparticles are photodeposited onto fabrics for cosmetic and medical clothing, the metal nanoparticles are firmly supported on titanium dioxide in the sheath component.

When the average diameter of the titanium dioxide is less than 15 nm, the metal nanoparticles are not firmly supported on the titanium dioxide when photodeposited, and when it exceeds 100 nm, the dispersibility of the titanium dioxide in the sheath component deteriorates. The crystal phase of the titanium dioxide may be a form having the photoactivity of the anatase phase or a form having a composite phase of anatase and rutile to increase the photoactivity.

It is preferable that the yarn constituting the spun yarn fabric of the present invention have a total fineness of 10 to 60 denier, but the present invention does not specifically limit the total fineness of the yarn.

The spun yarn fabric according to the present invention is in the form of a woven fabric or knitted fabric.

The spun yarn fabric according to the present invention has an antibacterial effect against Staphylococcus aureus and Streptococcus pneumoniae of 99.9% or higher as measured by the KS K 0698 method after 50 washes (i.e., after 50 washes using the KS K 0430 method for measuring color fastness to washing) and an ultraviolet ray blocking effect of 90% or higher as measured by the KS K0850 method.

Next, a method for manufacturing a functional spun yarn fabric according to the present invention will be examined.

The method for manufacturing a functional spun yarn fabric of the present invention is characterized by including: (i) a process of manufacturing a sheath-core type composite filament by composite spinning a core component composed of a polyester resin and a sheath component composed of a polyester resin containing 1 to 6 wt% of titanium dioxide (TiO2), and then manufacturing a composite staple fiber therefrom; (ii) a process of manufacturing a spun yarn by mixing the sheath-core type composite staple fiber with staple fibers composed of natural fibers or synthetic fibers, and then manufacturing a fabric with the spun yarn; and (iii) a process of immersing the fabric in a salt-type metal precursor solution and then irradiating ultraviolet rays for 4 to 60 seconds to photodeposit metal nanoparticles having an average diameter of 1 to 5 nm on the surface of the fabric. In addition, the process of manufacturing a fabric with the spun yarn by mixing the sheath-core type composite staple fiber with staple fibers composed of natural fibers or synthetic fibers, and then manufacturing a fabric with the spun yarn is characterized by including: Next, a process of weight-loss treatment of the fabric using an alkaline aqueous solution may be further included. The surface of the fabric for hospital clothing of the present invention may have fine irregularities formed by the alkali weight-loss treatment because the fine irregularities serve to more firmly support the metal nanoparticles on the surface of the fabric when the metal nanoparticles are photodeposited on the surface of the fabric.

Specifically, in the present invention, a spun yarn is manufactured by spinning a composite staple fiber of a sheath type by composite spinning of a core component composed of a polyester resin and a sheath component composed of a polyester resin containing 1 to 6 wt% of titanium dioxide (TiO2) having an average diameter of 15 to 100 nm, and a natural or synthetic staple fiber.

The above-mentioned sheath component can be manufactured by a method of dispersing the titanium dioxide (TiO2) nanoparticles in a melted bis-hydroxy ethylene terephthalate (hereinafter referred to as “BHET”) oligomer and polycondensing them with ethylene glycol, or a method of dispersing the titanium dioxide nanoparticles in an ethylene glycol solution using a dispersant and polycondensing them with BHET. In order to uniformly disperse the titanium dioxide (TiO2) nanoparticles in the sheath component, it is more preferable to add 0.3 to 0.5 wt% of a nonionic surfactant to the sheath component in the present invention.

Next, the above-mentioned composite staple fiber and the mixed spun yarn of natural or synthetic staple fiber are used as yarns for manufacturing fabrics, in other words, if the fabric is a woven fabric, the above-mentioned yarns are used as warp and weft yarns to manufacture the fabric.

Next, the manufactured fabric is immersed in a salt-type metal precursor solution and then irradiated with ultraviolet rays for 30 to 60 seconds to photodeposit metal nanoparticles having an average diameter of 1 to 5 nm on the surface of the fabric, thereby manufacturing the multifunctional spun yarn fabric of the present invention and its application products.

The above metal precursor solution in salt form can become a silver nitrate (AgNO3) solution when silver (Ag) is immersed in it.
