More specifically, the present invention relates to a method for forming a coating layer using a functional mixed solution in a spun yarn made of a synthetic resin material, Wherein the functional mixture solution comprises a composition exhibiting antibacterial and bactericidal properties and an inorganic composition exhibiting a far infrared ray emitting property and an anionic ion releasing property and having an antibacterial property, a bactericidal property, a far infrared ray emitting property and an anionic releasing property will be.

Since the fibers are in direct contact with the sweat of the human body, they may cause an unpleasant odor problem due to the generation of a large amount of ammonia, and microorganisms harmful to the human body may adhere to the fiber products and cause various diseases. In order to prevent the fiber product from being discolored or contaminated from harmful microorganisms or contaminated with various odors, antimicrobial and antifungal deodorization processing for inhibiting microorganisms such as bacteria and fungi from living or propagating is performed . The antimicrobial activity refers to a property of inhibiting the bacterial growth and sterilizing the bacteria. The term "antifungal" refers to a property of eliminating the generation of odor by suppressing the propagation of the mold and killing the mold, that is, the deodorizing and deodorizing property.

In addition, a method of applying an inorganic compound such as silver, copper, zinc, silver oxide and zinc oxide or applying an organic compound such as benzyl chloride is known as an antibacterial processing method. However, hygiene processing agents made of such antimicrobial compounds have problems in that they are not organically bonded to fibers and have durability due to washing.

On the other hand, Korean Patent Laid-Open Publication No. 10-1995-0056736 discloses an antibacterial antifungal core-sheath type conjugate fiber composed of a superficial part and a deep part. More specifically, it relates to a thermoplastic resin having a fiber- And a heat-resistant organic antimicrobial agent in a thermoplastic resin having a fiber-forming property with a melting point higher by 30 占 폚 or higher than that of a secondary component thermoplastic resin.

Disclosure of Invention Technical Problem [8] The present invention has been made in order to solve the problems of prior art fibers of a synthetic resin material. In the prior art, a functional material for exhibiting functionality such as antimicrobial activity, bactericidal activity, far-infrared ray releasing property, There is a problem that the functional layer is easily peeled off from the fiber since the functional layer is coated on the fiber in a particle state;

As a result, when water, such as cloth, bedclothes, or interior finish, made of functional fibers is washed or further washed, the functional material is easily peeled off from the fiber, resulting in poor durability;

In addition, since the functional material coated on the functional fiber has a very large particle size as compared with the diameter of the fiber, even if the functional material of the same mass is coated on the fiber, The main objective is to provide a solution.

The present invention has been made to solve the above-

A spun yarn mixed with 60 to 80% by weight of a polypropylene (PP) fiber yarn and 20 to 40% by weight of a polyethylene terephthalate (PET) yarn; And a coating layer formed on the outer surface of the yarn by a functional mixed solution containing a functional material in a nanoparticle state having a function of at least one of antimicrobial activity, bactericidal activity, far-infrared ray releasing property and anionic releasing property, , Far-infrared ray emitting property and anion releasing property.

The fiber having antimicrobial activity, bactericidal activity, far-infrared radiation releasing property and anion releasing ability according to the present invention as described above is a functional material for exhibiting functionalities such as antibacterial activity, bactericidal activity, far-infrared radiation releasing property, Since the nanoparticles are coated on the fibers, the effect that the functional material is not easily peeled off from the fibers can be obtained;

Particularly, even if water, such as cloth, bedding or interior finish, made of functional fibers is washed or water is washed, the functional material can not be easily peeled off from the fiber, and an excellent durability can be obtained;

In addition, since the functional material has a nanoparticle state, the surface area exposed to the outside is wider than that of the functional material particles of the same mass, which are coated on the fibers, and the effect of demonstrating the function is further improved.

The present invention relates to a fiber having functional properties such as antimicrobial activity, bactericidal activity, far-infrared ray releasing property, anion releasing property, and the like. The fiber comprises 60 to 80% by weight of a fiber material of polypropylene (PP) and a fiber material of polyethylene terephthalate 20 to 40% by weight of a yarn; And a coating layer formed on the outer surface of the yarn by a functional mixed solution containing a functional material in a nanoparticle state having a function of at least one of antimicrobial activity, bactericidal activity, far-infrared ray releasing property and anionic releasing property, , Far-infrared ray emitting property and anion releasing property.

Hereinafter, the present invention will be described in detail based on preferred embodiments of the present invention.

First, the fiber coated with the functional material in the nanoparticle state contained in the functional mixed solution according to the present invention may be a generally known synthetic resin fiber, and preferably, a fiber made of polypropylene (PP) and a polyethylene terephthalate It is preferable that it is made of a yarn obtained by blending fiber yarn made of phthalate (PET) material.

That is, the fiber according to the present invention may be a yarn-like yarn such as a spun yarn, a yarn-like yarn in which the yarn is woven, and preferably a yarn before the weaving in the form of a fabric. In this case, when the functional yarn of the following nanoparticles is coated on the yarn, the area exposed to the outside is wider than that of the fabric in which the twisted portions of one fiber yarn and the adjacent fiber yarns are formed, The coating property of the functional material becomes better and the coating area becomes wider.

In addition, the spun yarn is composed of 60 to 80% by weight of polypropylene (PP) fiber yarn and 20 to 40% by weight of fiber yarn of polyethylene terephthalate (PET) Lightweight property, and the polyethylene terephthalate is excellent in durability, heat resistance and antifouling property when used as a fiber yarn, and thus is used as various kinds of textile yarn for clothes.

At this time, the spun yarn having the above-mentioned constitution is made of a single yarn by blending a polypropylene fiber yarn and a polyethylene terephthalate fiber yarn, and in particular, the yarn of the present invention is a yarn of a kind such as work clothes, gown, bedding, Lightweight, durability, heat resistance, antifouling property and the like can be excellently exerted when it is used as a yarn of clothes of a garment of the present invention.

The polypropylene fibers and the polyethylene terephthalate fibers constituting the yarns may be blended in appropriate proportions according to the judgment of a person skilled in the art to be made into yarns and preferably made of polypropylene (PP) 80% by weight and 20 to 40% by weight of fiber yarns made of polyethylene terephthalate (PET).

At this time, if the ratio of the polyethylene terephthalate fiber yarn is less than 20 wt%, the durability of the polyethylene terephthalate fiber yarn may be insufficient, and the ratio of the polyethylene terephthalate fiber yarn may exceed 40 wt% The durability of the spun yarn is excellent but the proportion of the fiber yarn made of polyethylene terephthalate is high so that there is a possibility that the lightweight property is somewhat inferior. Therefore, the yarn spun yarn has a fiber yarn ratio of polypropylene and polyethylene terephthalate It is preferable to be made blended.

The coating layer may be formed on the outer surface of the yarn by a functional mixed solution containing nanoparticulate functional material having at least one of antimicrobial activity, bactericidal activity, far-infrared releasing property and anionic releasing property. Is capable of having at least one of antimicrobial activity, bactericidal activity, far infrared ray release property and anionic release property.

That is, the coating layer is formed by coating a functional mixed solution containing a functional material in a nanoparticle state on the outside of the spinning yarn having the above-described structure, and can be processed by a spray coating method, an impregnation coating method, or the like.

At this time, the spray coating method is a method in which a functional mixed solution containing a functional material in the form of nanoparticles is sprayed to the outside of a spinning yarn to form a coating layer on the outside of a spinning yarn. In the impregnating coating method, The solution is impregnated with a spun yarn to form a coating layer on the outside of the spun yarn.

In connection with the above, when the functional material is composed of nanoparticle-sized fine particles and is included in the functional mixed solution, the nanoparticulate functional material is inserted into the fine pores formed in the spinning yarn, and the functionalities can be exhibited by the fibers The yarn may be composed of 60 to 80% by weight of a polypropylene (PP) fiber yarn and 20 to 40% by weight of a polyethylene terephthalate (PET) fiber yarn The functional material is preferably configured to have an average particle size of 10 to 50 nm.

In this case, the particle size of the functional material may be varied within the above range depending on the number of yarns (which is a general unit representing the length of the yarn drawn per unit weight), and the particle size of the functional material is increased as the number of yarns is increased And the smaller the number of yarns, the smaller the particle size of the functional material is.

In addition, the thickness of the coating layer can be varied according to the use of the fiber according to the present invention, and may be formed on the outer side of the yarn, preferably 30 to 200 nm.

Also, the functional material in the form of nanoparticles contained in the functional mixed solution may contain various kinds of functional materials capable of realizing functionality of any one of antimicrobial property, bactericidal property, far-infrared releasing property and anionic releasing property to be realized by the fiber according to the present invention .

Specifically, when the fiber according to the present invention is intended to realize the above-described antibacterial and bactericidal properties, it may be composed of a functional material in the form of nanoparticles of at least one of zinc oxide and silver oxide, and is intended to realize far infrared ray emitting property and anionic ion releasing property In the case of nanoparticulate functional materials including tourmaline, sericite and loess (inorganic nanoparticles of the following form).

That is, the zinc oxide or silver oxide is a known substance having characteristics of antibacterial and bactericidal properties. In the present invention, those produced by a general production method can be used, but those made by an electrolysis method are preferably used.

At this time, when zinc oxide or silver oxide is obtained by an electrolysis method, any one of a positive electrode rod or a negative electrode rod used in electrolysis is made of pure zinc or silver, and then zinc or silver is oxidized during electrolysis Zinc oxide or silver oxide precipitated in the electrolyte is preferably used.

In addition, when zinc oxide or silver oxide obtained by electrolysis as described above is used as a functional material, zinc oxide or silver oxide separated from the electrolyte can be separated into pure zinc oxide or silver oxide by a known technique, The zinc oxide or the silver oxide may be more purely separated from other electrolyte ions or by-products contained in the electrolyte in the process of obtaining the following secondary solution.

In the case where the fiber according to the present invention is intended to realize the far-infrared ray emitting property and the anion releasing property, the functional mixed solution is prepared by pulverizing tourmaline, sericite and loess, and mixing the inorganic composition in nanoparticles form, The solution may be composed of the lower solution except the supernatant in the stationary solution made by letting the solution stand for 5 to 10 days.

That is, the functional mixed solution having the above-described constitution is obtained by pulverizing an inorganic composition such as tourmaline, sericite and loess into a nanoparticle state, mixing the pulverized inorganic composition with purified water and stirring the solution, .

At this time, the tourmaline, sericite and loess are minerals made of minerals and known as a known substance capable of releasing a large amount of far-infrared rays and anions, and a detailed description thereof will be omitted.

However, the mixing ratio of tourmaline, sericite and loess to be contained in the inorganic composition may vary depending on the use of the fiber according to the judgment of a person skilled in the art, and the weight ratio of tourmaline, sericite and loess is preferably 2: 5 to 7: 1 to 3, respectively.

The functional mixed solution according to the present invention can be obtained by finely pulverizing an inorganic composition such as tourmaline, sericite and loess into nanoparticles, mixing the pulverized inorganic composition with purified water, allowing the mixture to stand for 5 to 10 days, , Sericite and loess particles in pure state can be used.

At this time, foreign matters contained in tourmaline, sericite, yellow soil, etc. are floated in the supernatant of the stationary solution. In the present invention, the supernatant may be discarded and only the lower solution except the supernatant may be used.

Specifically, the tourmaline, sericite and loess are preferably pulverized to an average particle size of 10 to 50 nm, and the particle size of the inorganic composition is mixed with purified water to mix with the inorganic composition, The inorganic composition contained in the liquid does not dissolve in the purified water. Therefore, when the inorganic composition is left without stirring, it sinks to the bottom of the static solution. At this time, the supernatant located in the upper part of the stationary solution contains foreign matter having a small particle size, and tourmaline, sericite and loess in pure state are precipitated in the lower solution.

The inorganic composition suspension may be allowed to stand for a suitable time according to the judgment of a person skilled in the art, as long as it can be made to be a stationary solution by being allowed to stand for a standing time to obtain a lower solution containing the inorganic composition nanoparticles in a pure composition , Preferably for 5 to 10 days.

At this time, if the settling time of the inorganic composition turbid solution is less than 5 days, the settling time of the inorganic composition turbid solution is somewhat short, so that the foreign matter to be contained in the supernatant may not be floated by the supernatant, If the standing time of the inorganic composition suspension is excessively long, the foreign matter suspended in the supernatant may be re-agglomerated and precipitate in the lower solution. Therefore, It is preferable that the settling time of the turbid solution is within the above range.

Further, in order to obtain the above-mentioned lower solution, the present invention may be such that the suspension of the inorganic composition is accommodated in a certain container and buried in the ground for a fixed period of time to form a stationary solution.

At this time, if the suspension of the inorganic composition is allowed to stand in the paper as described above, the stable precipitation of the inorganic composition can be induced with little temperature change during the standing time, and various kinds of bacteria or viruses Can be minimized.

In addition, it is preferable that the container containing the slurry of the inorganic composition is buried at a depth of 1 m or less in the ground so as not to receive the maximum temperature change of the ground, and the rice straw is inserted between the container and the underground soil, Or the worm may not be introduced into the container.

Also, the lower solution obtained from the static solution as described above, that is, the lower solution containing the nanoparticle-sized inorganic composition may be directly used as the functional mixed solution, and preferably the inorganic composition contained in the lower solution may be further subdivided The lower solution is mixed with purified water, ball milled, and then allowed to stand for 1 to 3 days. The solution is made into a secondary lower solution except supernatant, and can be used as a functional mixed solution.

That is, the secondary settling solution is prepared by mixing undiluted water in the above-mentioned lower solution and further finely pulverizing an inorganic composition having a relatively large particle size (particle size of 50 nm or more) among the tourmaline, sericite and yellow soil contained in the stationary solution by using a well- And the solution is allowed to stand for a predetermined time, and the secondary lower solution corresponds to the lower solution except the upper water in the secondary solution.

At this time, the process for preparing the secondary lower solution may be performed in the same manner as the process for obtaining the lower solution in the stationary solution, and a detailed description thereof will be omitted from the description of the process for obtaining the lower solution.

In connection with the above, it is possible to perform various treatments according to the judgment of a person skilled in the art depending on the amount of the lower solution of the ball mill treatment of the solution in which the lower solution and the purified water are mixed. Can be processed in various ways.

However, since the standing time for making the secondary stabilizing solution is a step for restoring the secondary stabilizing solution made by ball milling, considering the pure state of the inorganic stabilizing agent contained in the stabilizing solution, It is preferable to be treated for a shorter period of 1 to 3 days.

When the fiber according to the present invention is intended to achieve both antimicrobial activity, bactericidal activity, far-infrared ray releasing property and anion releasing property, the functional mixed solution may contain zinc oxide or silver oxide One or more antimicrobial and bactericidal compositions may be included.

At this time, a detailed description of the secondary lower solution and a detailed description of the antibacterial and bactericidal composition will be substituted for the above description.

However, the mixing ratio of the secondary lower solution and the antibacterial and bactericidal composition may be appropriately adjusted according to the use of the fiber according to the present invention, but it is preferable that the antibacterial and bactericidal composition 0.5 to 2 parts by weight.

In addition, as described above, the functional mixed solution of the composition can be coated on the spinning yarn in such a manner as the spray coating method or the impregnation coating method to realize the antibacterial property, the bactericidal property, the far infrared ray emitting property and the negative ion releasing property of the fiber, And may be made into articles such as cloth, bedclothes or interior finishes.
