Description

Eco-friendly functional clothing with deodorizing and antibacterial properties

The present invention relates to eco-friendly functional clothing having deodorizing and antibacterial functions. More specifically, the present invention relates to eco-friendly functional cotton yarn having deodorizing and antibacterial functions by using eco-friendly natural materials that are harmless to the human body without using chemicals, and to eco-friendly functional clothing manufactured using the same.

Cotton used in the production of cotton yarn is an annual plant belonging to the Malvaceae family. It is an annual plant in temperate regions, but in its native tropical regions, it grows as a woody plant to 180 cm to 210 cm. It likes a hot and humid climate, and its optimal growing temperature is 20 to 28°C. After fertilization, the seed grows larger, the ovary develops, and the fruit is called a dare, and when the dare splits, the cotton, which is the raw material for cotton, is exposed. Cotton cultivation in Korea began in 1363 when Mun Ik-jeom brought Asian cotton seeds in a brush when he returned from his visit to the Yuan Dynasty as a minister. Production greatly increased after the introduction of land cotton in 1905. It is also called cotton, miyeong, and mimyeon, and its scientific name is Gossypium indicum LAM. It is an annual plant in temperate regions, but in its native tropical regions, it is a woody plant. In Korea, it is only about 90 cm tall, but in tropical regions, it can grow to 180-210 cm. The main stem grows straight and has about 15 nodes, and each node has a leaf and two lateral buds.

Cotton fibers are mainly used for textile purposes such as cotton yarn, cotton fabric, cotton blends, and nets, for cotton manufacturing such as quilt cotton, cotton for clothing, and cotton batting, and for industrial purposes such as gunpowder and celluloid. Cotton fruits are pressed for oil and used in the production of edible oil, butter, margarine, etc.

Meanwhile, sweat from the human body has no smell immediately after secretion, but when it reacts with dead skin cells and bacteria on the skin, it generates ammonia with a pungent smell and acetic acid with a sour smell. There is a need to develop functional clothing that can reduce such smells. Therefore, the present invention has developed a functional cotton yarn that has an antibacterial function that blocks bacteria that react with sweat from the human body, a deodorizing function that removes bad smells, and an antibacterial function that prevents sweat stains from appearing, and this can be used as eco-friendly functional clothing.

The present invention is capable of various modifications and applications within the scope of the following claims and equivalents interpreted therefrom.

In addition, the terms used in this specification are terms used to appropriately express preferred embodiments of the present invention, and may vary depending on the intention of the user or operator, or the customs of the field to which the present invention belongs. Therefore, the definitions of these terms should be made based on the contents throughout this specification. Throughout the specification, when a part is said to "include" a certain component, this does not mean that other components are excluded, but rather that other components can be further included, unless specifically stated otherwise.

Throughout this specification, '%' used to indicate the concentration of a particular substance, unless otherwise stated, is (w/w) % for solid/solid, (w/v) % for solid/liquid, and (v/v) % for liquid/liquid.

In one aspect, the present invention provides a method for manufacturing an eco-friendly functional cotton yarn.

The method for manufacturing an eco-friendly functional cotton yarn according to the present invention manufactures cotton yarn through a honing step, a carding step, a regularizing step, a drawing step, a spinning step, a square spinning step, and a winding step.

The mixing step in the eco-friendly functional cotton yarn manufacturing method according to the present invention is a process of loosening cotton lumps, removing dust and impurities, and squeezing them. Specifically, it is a process of mixing them evenly to obtain a certain quality of cotton fibers, and the clumped cotton is shaken and beaten to ensure complete mixing. During this process, impurities such as seeds and leaves are removed.

In the method for manufacturing an eco-friendly functional cotton yarn according to the present invention, the mixing step further specifically includes a step of treating cotton cotton from which dust and impurities have been removed and mixing a mixed extract of tangerine peel, lemon peel, orange peel, and yuzu peel, which are discarded in lumps, for 24 to 48 hours and then drying to allow the natural extracts to be absorbed and coated. At this time, the treatment and drying steps are repeated three times so that the effective ingredients of the natural extracts can be sufficiently absorbed and coated on the cotton cotton.

The carding step of the eco-friendly functional cotton yarn manufacturing method according to the present invention is a process for making slivers by once again separating the fibers that are clumped together through the mixed-up step. Specifically, after the mixed-up step, the cotton is fed into a carding machine for primary combing. The cotton is put into a machine with a thin needle that moves up and down and in the opposite direction and rotated. The cotton is torn by the needle, and the fine cotton and dust that do not meet the standard fall to the floor. At this time, the carding machine looks like a threshing machine used in rural areas, and the cotton is combed by passing over the thin comb on the cylinder. After the carding process, it is too short to be made into yarn. It is a process for aligning cotton fibers in one direction, and after one combing with low-grade yarn, it moves on to the drawing process.

The combing step of the eco-friendly functional cotton yarn manufacturing method according to the present invention is a process of combing the 1st sliver once more to completely remove impurities, and combed cotton yarn (combed yarn) has greater strength and better uniformity than carded yarn. Specifically, the sliver after carding has not yet completely removed short fibers and contains neps, short cotton fibers the size of rice grains, that are tangled. Therefore, in order to obtain finer and higher-quality yarn, the sliver must be combed again to completely remove short fibers and neps and arrange the fibers more parallel. The principle of the process is similar to the 'principle of a fine comb'. This is a process of passing the cylinder with combs that are finer and more closely spaced than the combs of a carding machine. The yarn produced through two combings is mainly used to make expensive products because it has undergone a combing process. Since the yarn has no impurities, it has good gloss and dyeability and feels good.

In the eco-friendly functional cotton yarn manufacturing method according to the present invention, the softening step is a process of combining 6 to 7 strands of the 1st or 2nd sliver 2 to 3 times and then thinning them out again. When mixing different types of fibers, they are mixed in this process. Specifically, the cotton yarn that has passed through the carding or regularizing step has a shape of a cotton-like stick, which is called a sliver. This is a process of combining 6 to 8 slivers, rolling them into one dense and long sliver, and putting them into a drum or the like, and evenly making them into cotton strips with a width of about 30 cm and a thickness of about 1 cm.

In the eco-friendly functional cotton yarn manufacturing method according to the present invention, the roving step is a process of stretching the sliver, which has been made thin and even in the roving process, into a thinner diameter and winding it onto a tube, as the yarn cannot be directly drawn from it. Specifically, the roving is about the thickness of udon, and here, further twisting is applied and the final draft is applied to draw out the final finished product, the yarn. The yarn is drawn by winding the arranged cotton around a pin while twisting it. Usually, a ring spinning machine is used, and the twist number is determined by the difference in the speed at which the yarn is unwound and the speed of the spinner below.

The spinning step in the eco-friendly functional cotton yarn manufacturing method according to the present invention is a process of twisting yarn to obtain a desired thickness and winding it on a bobbin. It is a step in which the twist or count quality of the yarn and the productivity of the yarn are determined during the entire spinning process, and ring-spun/open-ended yarn is determined depending on the type of spinning machine.

Among the eco-friendly functional cotton yarn manufacturing methods according to the present invention, the winding step is a process of winding yarn to become a product.

Meanwhile, in the method for manufacturing an eco-friendly functional cotton yarn according to the present invention, the mixing step further specifically includes a step of treating cotton cotton from which dust and impurities have been removed and mixing a mixed extract of tangerine peel, lemon peel, orange peel, and yuzu peel, which are discarded in lumps, for 24 to 48 hours and then drying to allow the natural extracts to be absorbed and coated. At this time, the treatment and drying steps are repeated three times so that the effective ingredients of the natural extracts can be sufficiently absorbed and coated on the cotton cotton.

The extract according to the present invention can be obtained by extracting and separating from a natural material using an extraction and separation method known in the art, and the "extract" defined in the present invention is extracted from tangerine peel, lemon peel, orange peel, and yuzu peel using an appropriate solvent, and includes, for example, a crude extract, a polar solvent-soluble extract, or a non-polar solvent-soluble extract. Any organic solvent acceptable in terms of food or cosmetics may be used as a suitable solvent for preparing extracts from the tangerine peel, lemon peel, orange peel and yuzu peel, and water or an organic solvent may be used, but is not limited thereto. Examples thereof include purified water; alcohols having 1 to 4 carbon atoms, such as methanol, ethanol, propanol, isopropanol and butanol; acetone, ether, benzene, chloroform, ethyl acetate, methylene chloride, hexane and cyclohexane, and various solvents may be used alone or in combination. As an extraction method, any one of the following methods may be selected and used: hot water extraction, cold immersion extraction, reflux cooling extraction, solvent extraction, steam distillation, ultrasonic extraction, dissolution, and pressing. In addition, the desired extract may additionally undergo a conventional fractionation process and may be purified using a conventional purification method.

There is no limitation on the method for producing the extract of the present invention, and any known method can be used. For example, the extract included in the composition of the present invention can be produced in a powder form by additional processes such as reduced pressure distillation and freeze drying or spray drying of the primary extract extracted by the above-mentioned hot water extraction or solvent extraction method. In addition, the primary extract can be obtained by further purifying fractions using various chromatography such as silica gel column chromatography, thin layer chromatography, high performance liquid chromatography, etc. Therefore, in the present invention, the extract is a concept including all extracts, fractions, and purified products obtained at each stage of extraction, fractionation, or purification, and their dilutions, concentrates, or dried products.

Hereinafter, embodiments of the present invention will be described in more detail with reference to the attached drawings. However, the following embodiments are only intended to concretize the contents of the present invention, and the present invention is not limited thereby.

<Experimental Example 1> Deodorizing Function Verification Test

According to Table 1 of the above Manufacturing Example 2, natural extracts were treated to absorb and coat cotton, and cotton yarn was manufactured according to the manufacturing process of Manufacturing Example 1. The manufactured cotton yarn was made into fabric for clothing using a weaving machine, and the deodorizing function was tested using the fabric.

A 30 ^cm2 fabric manufactured by processing each extract was placed in a 1 liter container, and a concentration of ammonia gas known to be 500 ppm, which is generated when sweat secreted from our body reacts with dead skin cells and bacteria on the skin, was injected into the container. The residual concentration of ammonia gas was then measured after 60 and 120 minutes, and the deodorizing rate was calculated according to the following mathematical formula. The experiment was performed three times for each sample, the average value was obtained, and the results were obtained using the above formula, which are shown in Table 2 below.

[Mathematical formula 1]

Deodorization rate (%) = (C ₀ -C ₁ )/C ₀ X100

At this time, C ₀ represents the gas concentration before sample injection, and C ₁ represents the gas concentration after sample injection.

Deodorization rate (%) beginning 60 minutes later 120 minutes later Example 1 0.0 13.4 15.1 Example 2 0.0 21.1 26.2 Example 3 0.0 13.7 17.1 Example 4 0.0 9.1 11.2 Example 5 0.0 37.1 42.7 Example 6 0.0 43.2 57.1 Comparative Example 1 0.0 5.1 8.4 Comparative Example 2 0.0 31.2 33.2 Comparative Example 3 0.0 37.1 44.4 Comparative Example 4 0.0 34.8 41.8

As shown in Table 2 above, in Examples 1 to 4, which were fabrics manufactured from cotton treated with each extract individually, a low deodorizing rate was confirmed, whereas in Examples 5 and 6, which were mixed extracts, and in Comparative Examples 2 to 4, which used different extraction solvents, a relatively high deodorizing rate was confirmed. In particular, the highest deodorizing rate was confirmed in Example 6, which was fabric manufactured using cotton treated with a mixed extract of tangerine, lemon, orange, and yuzu ethanol extracts in a weight ratio of 2:3:2:1, and then absorbed and coated.

<Experimental Example 2> Antibacterial function confirmation test

According to Table 1 of the above Manufacturing Example 2, natural extracts were treated to absorb and coat cotton, and cotton yarn was manufactured according to the manufacturing process of Manufacturing Example 1. The manufactured cotton yarn was used to make fabric for clothing using a weaving machine, and its deodorizing function was confirmed. In order to confirm the direct antibacterial function of the extracts treated to cotton, the following experiment was conducted. This can be used as a direct clothing deodorant with an antibacterial effect in addition to being included in clothing fabric.
