Recently, due to the outbreak of the corona virus, the demand for antibacterial clothing and masks is increasing not only in hospitals but also in the general public. It remains in the clothing and causes discomfort. In particular, with the advent of an aging society, there is a need to eliminate the peculiar smell of the elderly that occurs in the elderly.

Accordingly, the development of fibers or fabrics having antibacterial and deodorizing functions is attracting attention due to this background.

In addition, since microbes are easily propagated by sweat and external contamination of the human body, a large amount of ammonia is generated by the propagated microbes, causing unpleasant odors as well as harmful problems such as skin diseases.

For this reason, many attempts have been made to impart the function of inhibiting the growth of harmful bacteria to the human body from the past.

As a method of imparting antibacterial and deodorizing properties to fibers, organosilicon-based quaternary ammonium salt compounds are currently widely used, but laundry durability is poor and, in particular, when a chlorine-based detergent is used in the washing process, the fibers are yellowed.

1 to 4 are test reports in which the antibacterial and deodorant performance of the present invention was tested by the FITI Test Research Institute.

Hereinafter, the present invention will be described in detail with reference to preferred embodiments of the present invention and the accompanying drawings.

When it is said that any one component "includes" another component in the detailed description or claims of the invention, it is not construed as being limited to only the component unless otherwise stated, and other components are not construed as being limited thereto. It should be understood that more may be included.

The functional deodorant fabric according to the present invention is woven with a fiber using polyester as a base resin, a fiber extracted from a mulberry tree, and a Korean paper fiber.

Fibers using polyester as a base resin are composed of inorganic ceramic fine particles and polyester resins mixed together.

In the inorganic ceramic fine particle powder used in the present invention, copper, silver, and iron components are substituted in the porous inorganic ceramic fine particle powder, and the substituted metal oxide chemically adsorbs with the molecules of the odor component to exhibit a deodorizing effect as well as temperature Because it is stable against and humidity, it has excellent durability.

And metal ions destroy the metabolism of microorganisms to exhibit antibacterial properties, and the porous surface area and substituted metal oxides adsorb and remove odor components.

The porous inorganic ceramic fine particle powder used in the present invention is a binder of metal ions, and a silica alumina-based inorganic material having a specific surface area of 100 to 800 m 2 /g in a component composition is molded to a particle size of 1 μm or less, It is used by drying at a temperature of 200 to 600 °C.

The metal ion-substituted porous inorganic ceramic fine particle powder is mixed with 2 to 20 parts by weight based on 100 parts by weight of the polyester resin and composite spinning to prepare a polyester-based fiber.

If the metal ion-substituted porous inorganic ceramic fine particle powder is less than 2 parts by weight based on 100 parts by weight of the polyester resin, the antibacterial and deodorant effects expressed in the fibers are not sufficient. also has no point

The antibacterial and deodorizing functions of polyester-based fibers are determined by the amount of substituted metal present in the porous inorganic ceramic fine particles. In order for effective antibacterial and deodorizing functions to be expressed by the porous inorganic ceramic fine particle powder in which 2 to 20 parts by weight is mixed with respect to 100 parts by weight of the polyester resin, the amount of the substituted metal is 5 to 30 parts by weight based on 100 parts by weight of the porous inorganic ceramic fine particle powder. make it an addition.

If the amount of the substituted metal present in the porous inorganic ceramic fine particle powder is less than 5 parts by weight, the antibacterial and deodorant effects are not sufficiently expressed. It is preferable that the amount of the substituted metal present in 100 parts by weight of the porous inorganic ceramic fine particle powder is 5 to 30 parts by weight.

Among the methods of adding metal ion-substituted inorganic ceramic fine particles to fibers, the method of adding them during polymerization is a method in which a metal component present on the surface of the ceramic acts as a catalyst during the polymerization reaction, so that non-reaction occurs during the polymerization reaction, or the metal ions A problem of changing the color of the resin may occur by forming a complex compound.

Therefore, in the present invention, 2 to 20 parts by weight of inorganic ceramic fine particles are mixed with respect to 100 parts by weight of the polyester resin and dispersed in the extruder during the spinning process.

As the polyester resin, polyester having an intrinsic viscosity of 0.5 to 0.8 was used, and the inorganic ceramic fine particle powder substituted with metal ions was mixed in an amount of 2 to 20 parts by weight based on 100 parts by weight of the polyester having an intrinsic viscosity of 0.5 to 0.8. and dispersed in the extruder to prepare a fiber using polyester as a base resin.

If the intrinsic viscosity of the polyester resin is less than 0.5, dispersibility is lowered, and if the intrinsic viscosity exceeds 0.8, workability deteriorates and fiber production becomes difficult, so it is preferable to use a polyester resin having an intrinsic viscosity of 0.5 to 0.8.

In the present invention, fibers extracted from mulberry trees are added together with the fibers using the polyester as a base resin.

The mulberry tree is a deciduous broad-leaved shrub in the mulberry family, and is also called the oak tree, the mulberry tree, and the low tree.

It is mainly distributed in Korea, Japan, and Southeast Asia, and is called gupima as a herbal medicine name, and contains saponin, milk fat, serotin, etc., so young branches and leaves are effective for bruises and used as a nourishing tonic.

The method of extracting fibers from the mulberry tree is as follows.

As the primary processing, the mulberry bark is treated with alkali such as caustic soda to remove the outer skin to prepare the inner skin material containing fibers.

The alkali treatment is preferably immersed in a solution of 10 to 15% by weight of caustic soda and boiled for 1 to 3 hours. In this process, the mulberry bark becomes more flexible, the fiber binding material and non-fibrous material are removed to some extent, and the outer skin is completely removed.

As a secondary processing, the primary processed inner skin is soaked in a bleaching agent such as an aqueous solution of hypochlorous acid and processed into white skin.

As a tertiary processing, the fiberization process of white mulberry bark is a fibrillation process in which the mulberry fibers are crushed by tapping the undercoat with a bat for 40 to 50 minutes. In the present invention, the fibrillation process is performed using a beater.

In the fourth processing, the fiber binding material of the mulberry tree that has undergone the fibrillation process is removed.

Paper mulberry fibers in the form of pulp that have undergone fibrillation become tangled and harden if left as they are, making it difficult to process. This is because substances such as pectin and lignin that bind fibers remain and dry the fibers to bind them and make them hard. do.

Looking at the composition of mulberry fiber, it is composed of about 70-85% of cellulose, 7-10% of extracts such as water, alkali, and organic solvent, 7-10% of pectin, 3-5% of lignin, and 2-5% of ash. Pectin, which is widely distributed in the middle plant kingdom, mainly binds to the intercellular layer or the primary wall of young cells and acts as a binder to compose plant tissue, and acts as an important fiber binding material of the bast fiber system such as hemp, flax and hemp. .

Even in the case of mulberry bast fibers, a large amount of pectin exists, and such interfiber pectin binds to lignin and plays an important role in binding the bast fibers to each other with insolubilized pectin, and in particular, it has a more complex chemical structure and is not easily removed.

In the present invention, a chemical method of treating the mulberry pulp that has been dissolved in the quaternary processing with an alkali agent, for example, caustic soda, potassium carbonate, sodium carbonate, potassium persulfate, or a biochemical method of treating with a pectin-degrading enzyme such as pectanase Method or the chemical method or biochemical method in parallel to effectively remove the fiber binding material of the mulberry tree.

The mulberry fiber is manufactured through the process as described above.

Hanjisa is manufactured through the process of manufacturing the mulberry fiber and other processes added thereafter.

A dissociation step of dissolving the mulberry fibers dissolved through the quaternary processing of the mulberry fibers described above and polyester-based fibers in water, mixing them in a predetermined ratio, and mixing is performed.

It is desirable to use a screw to stir the completely loosened raw material (paper made from mulberry pulp and polyester as the base resin) with water so that it is evenly mixed with water so that the fibers that have been beaten through the quaternary processing are completely loosened. do.

The mixing ratio of mulberry fiber pulp and fiber pulp using polyester as the base resin is such that 30 to 50% by weight of mulberry fiber pulp and 50 to 70% by weight of fiber using polyester as the base resin are mixed.

When mulberry fiber pulp is mixed, heat retention, breathability, deodorization and deodorization properties increase. When the mulberry fiber pulp is mixed at less than 40% by weight, it is difficult to obtain these effects, and when the fiber using polyester as the base resin exceeds 70% by weight, Since there is a problem in that the fiber to be spun is easily broken, it is preferable to mix 30 to 50% by weight of mulberry fiber pulp and 50 to 70% by weight of a fiber using polyester as a base resin.

As described above, a viscous agent obtained by mixing mulberry, palm oil and surfactant is added to a mixture of mulberry fiber pulp and polyester fiber as a base resin, and the mixture is spun and extracted into fibers.

A fabric is produced by weaving the above-described polyester as a base resin, mulberry fiber, and Korean paper yarn with a weft or warp yarn, respectively, or by weaving a yarn formed by twisting a plurality of fibers to produce a fabric.

The present invention configured as described above has antibacterial, deodorizing, anti-inflammatory, anti-static, etc. functionality, and has the effect of maintaining functionality even after using it for a long time.
