Normally, when a person died with the end of his life, the body was placed in a wooden coffin made of wood for funeral, and then buried in the ground to create a cemetery. In addition, in recent years, because Korea's land is cramped, it is turning to a more efficient funeral method, crematory.

However, the number of cremation facilities is very short due to air pollution caused by cremation and the Nimbi phenomenon due to hate perception of cremation facilities, and thus many restrictions are placed on the use of cremation facilities.

In addition, burial or cremation as described above can pollute the soil or the atmosphere due to the influence of the funeral coffin in which the body is placed and the accessories attached to the funeral coffin. Most of the time, at the request of the bereaved family who leaves the deceased, the soil or atmosphere Pollution is postponed as a subsequent problem, and funeral coffins with excellent solidity and beauty are preferred.

The following is a typical prior art for a funeral coffin.

[Eco-friendly funeral coffin]

The present invention relates to an eco-friendly funeral tube made by heat-treating a felt made using raw materials consisting of 25 to 35 parts by weight of synthetic resin fiber and 60 to 80 parts by weight of low melting point fiber and then press-molding based on 100 parts by weight of natural fiber. will be.

First, the eco-friendly funeral coffin (hereinafter referred to as'funeral coffin') according to the present invention is configured in the same shape as a known funeral coffin, and preferably a body having an inner space in which the body is placed And a lid that is covered on the upper portion of the body and seals the open portion of the upper portion of the inner space.

At this time, the body is configured to include a lower plate and a plurality of side plates erected on the side of the lower plate, the lower plate and the plurality of side plates are connected to each other to form an inner space having an upper portion open.

In addition, the lid is a configuration that is covered on the upper portion of the body to seal the upper portion of the inner space in which the body is placed, and may be configured in various forms as long as it completely covers the inner space and can be tightly covered with the body.

In addition, the funeral tube according to the present invention is macroscopically composed of natural fibers, synthetic resin fibers, and low melting point fibers.

That is, the natural fiber allows the funeral coffin to have a certain strength, and at the same time, when the funeral coffin in which the body is placed is buried, the biodegradability of the funeral coffin is better than that of ordinary wooden coffins, It has the effect of allowing the body and coffin to rot faster.

In addition, if the natural fibers are of a material that can be fiberized according to the judgment of a person skilled in the art, fibers such as flax, hemp, jute, bamboo, abaca, coconut, etc. Any one or more of them may be used, and more preferably, Kenaf may be used.

That is, the Kenyaf (Kenaf) is an annual herbaceous plant belonging to the Malvaceae family, and is a plant produced in various parts of the world belonging to tropical and subtropical climates. In addition, Kenyaf is generally used as a material for purposes such as bags, ropes, carpet materials, insulation materials, or feed. Compared to other bast fibers such as ramie and hemp, Kenyaf has more non-fiber components and is stiff, so it is not frequently used as a material for clothing. I couldn't.

In addition, the Kenyaf may be composed of an outer bast portion and an inner inner portion of the stem, and the Kenyaf in the present invention may use one or more of the bast portion and the innermost portion, preferably the You can use the bast part.

In more detail, the Kanaf used as natural fiber in the present invention is separated by peeling off the bast part from the Kanaf stem, and the separated bast part is retted to obtain a fibrous Kanaf bast part. , Can be used to remove impurities and pigments by refining and bleaching the fibrous cannaf bast.

In addition, the bleached fibrous Kanaf bast portion may be dyed so that a funeral tube of various colors may be implemented.

In addition, the fibrous cannaf bast portion of the above configuration is made of cellulose as the main portion, and is composed of about 10 to 22% of lignin, pectin, and hamicellose. In addition, since the lignin of the above composition ratio makes the fiberized Kanaf bast part very stiff, which makes it difficult to spin due to low fiber composition (tangling property), the present invention makes the raw material containing the Kanaf bast part of the above configuration into a felt and pressurized. It is desirable to form a funeral coffin by molding.

In addition, Kanaf of the above configuration exhibits stronger mechanical strength than general pulp due to the characteristics caused by the lignin component, so that the funeral tube according to the present invention can be prevented from being bent or damaged even by the weight or external force of the body. have. In addition, since Kanaf is known to have antibacterial, deodorant and environmental hormone removal functions, it is possible to realize the effect of reducing bacteria and odors generated from the body before burial or cremation.

In addition, the synthetic resin fiber reinforces the strength of natural fibers, which are the main raw materials for the funeral coffin, and secures the dimensional stability of the funeral coffin against moisture that may be applied to the produced funeral coffin. If the material has a stronger mechanical strength, various types of materials can be used, and it is preferable to use a material having excellent biodegradability.

That is, the synthetic resin fibers may be of various types as long as they are of a material having a certain strength and excellent biodegradability according to the judgment of a person skilled in the art, and may be preferably composed of aliphatic polyester synthetic fibers.

More specifically, since the aliphatic polyester synthetic fiber has a general strength of polyester fiber, it can exhibit mechanical strength superior to that of general natural fibers (especially, Kanaf); Since biodegradability has superior properties than general polyester fiber, when the funeral coffin according to the present invention is buried, it is quickly decomposed compared to general synthetic resins that cannot be easily decomposed, and the effect of preventing soil contamination is realized. I can make it.

In addition, the synthetic resin fiber of the above configuration may have an appropriate composition ratio to the raw material for making the following felt according to the judgment of those skilled in the art, and preferably may have a composition ratio of 25 to 35 parts by weight based on 100 parts by weight of the natural fiber.

That is, if the synthetic resin fiber is contained in an amount of less than 25 parts by weight based on 100 parts by weight of natural fiber, the composition of the synthetic resin fiber is insufficient and there is a concern that the effect of improving the strength of the funeral tube by the synthetic resin fiber is insufficient. The effect of improving the strength of the funeral tube is excellent, but the composition of the synthetic resin fiber, which is less biodegradable than the natural fiber, is excessive, and there is a concern that the biodegradability of the manufactured funeral tube is insufficient, so that the synthetic resin fiber maintains the above composition ratio. It is desirable.

In addition, the low melting fiber is a configuration for bonding the natural fiber and the synthetic resin fiber by melting when the raw material is made into felt and then heat-treated, and is made of a material having a melting point lower than that of the synthetic resin fiber. It is preferable to use, and when a certain amount of heat higher than the melting point of the low melting point fiber is applied, it is melted to bond the natural fiber and the synthetic resin fiber to each other.

At this time, the low-melting fiber may be of an appropriate material according to the type of synthetic resin fiber, and preferably, when the synthetic resin fiber is composed of an aliphatic polyester synthetic fiber, polyethylene terephthalate (PET, polyethylene terephthalate), poly Any one or more of propylene (PP, polypropylene) or polyethylene (PE, polyethylene) may be used.

In addition, the low melting point fiber may be included in a composition ratio appropriate to the raw material, and preferably may be included in a composition ratio of 60 to 80 parts by weight based on 100 parts by weight of the natural fiber.

In this case, the composition ratio of the low-melt fiber is included in the raw material as the composition ratio of the low-melt fiber increases as the composition ratio of the synthetic resin fiber increases within the above range.

In addition, when the composition ratio of the low-melting fiber is included in less than 60 parts by weight based on 100 parts by weight of natural fiber, the composition of the low-melting fiber is insufficient, resulting in a problem that the bonding property between the natural fiber and the synthetic resin fiber due to the low-melting fiber is deteriorated. If it exceeds 80 parts by weight, the composition of the low-melt fiber is excessive, so that the molded felt may stick to the mold during pressure molding of the heat-treated felt, so it is preferable to maintain the composition ratio of the low-melting fiber.

In addition, as described above, the raw material formed by mixing natural fibers, synthetic resin fibers and low-melting fibers may further include 2 to 7 parts by weight of a water repellent based on 100 parts by weight of natural fibers.

That is, the water repellent is a composition that blocks moisture that may occur in the body placed in the manufactured funeral coffin or moisture that can penetrate into the body from the outside of the funeral coffin, and is preferably polyethylene terephthalate (PET, polyethylene terephthalate). ), polypropylene (PP, polypropylene) or polyethylene (PE, polyethylene), minimize damage to the body by water repellent, and use water repellent at burial of the funeral coffin in which the body is placed. It is desirable to minimize contamination of the soil, and to minimize air pollution caused by carbonized water repellent smoke generated during cremation of a funeral coffin in which the body is placed.

At this time, the water repellent may be included in the raw material at an appropriate composition ratio according to the judgment of a person skilled in the art, and preferably may be included in a composition ratio of 2 to 7 parts by weight based on 100 parts by weight of the natural fiber.

That is, if the water repellent contains less than 2 parts by weight based on 100 parts by weight of natural fiber, the composition of the water repellent may be insufficient, and the water repellent effect of the funeral coffin by the water repellent may be insufficient. Although the water repellency of the water repellent becomes excellent, damage to the body, soil pollution, or air pollution may occur due to the water repellent, so it is preferable to maintain the composition ratio within the above range.

In addition, as described above, the raw material formed by mixing natural fibers, synthetic resin fibers and low melting point fibers may further include 5 to 10 parts by weight of jellyfish powder based on 100 parts by weight of natural fibers.

That is, the jellyfish powder is a constitution that exhibits deodorizing properties to remove odors generated during decay of a body placed in a funeral coffin. In more detail, the jellyfish is a class of desperate animals belonging to the Jellyfish family, and 94-98% of the adult body is composed of water, and the main component of the jellyfish is composed of gelatin, a protein, and the mucin component that makes the jellyfish smooth is protein. Chondroitin, a combination of sugar and sugar, is known as the main component.

In addition, the jellyfish does not have any special taste or aroma when the salt is removed, and the exact cause is unknown, but in the present invention, it is possible to obtain an effect of absorbing the odor of the body and exerting deodorization.

In addition, the jellyfish may be pulverized after desalting and drying treatment to be included in the raw material, and preferably pulverized to have a particle size equal to or smaller than the diameter of the natural fiber, synthetic resin fiber and low melting point fiber. You can use what has been made.

In addition, if the jellyfish powder is contained less than 5 parts by weight based on 100 parts by weight of natural fiber, the composition of the jellyfish powder is insufficient, and there is a concern that the deodorization of the funeral tube by the jellyfish powder is somewhat insufficient. The deodorizing property of the funeral coffin becomes excellent, but since there is a concern that the strength of the funeral coffin may be impaired by excessively contained jellyfish powder, the jellyfish powder preferably maintains the above composition ratio.

In addition, as described above, the raw material formed by mixing natural fibers, synthetic resin fibers and low melting point fibers is made of felt and then heat-treated with heat enough to melt the low melting point fibers, and then press-molded according to the present invention. It is made as a funeral coffin.

In connection with the above, the felt (Felt) is not made by weaving fibers, but refers to a fabric obtained by rubbing the natural fibers, synthetic resin fibers and low melting point fibers under warm compression and entangled fibers by the fusion properties of the fibers. In addition, since the felt is made by milling a thin layer of fibers without passing through a thread, there is no surface texture so that the funeral tube can have a certain elasticity, and as a result, when an external force is applied to the funeral tube, the inner space is The effect of making the enshrined body more stable from external forces can also be realized.

[Eco-friendly funeral coffin manufacturing method]

The present invention is a raw material mixing process (S100) for making raw materials by stirring and mixing 25 to 35 parts by weight of synthetic resin fibers and 60 to 80 parts by weight of low melting point fibers based on 100 parts by weight of natural fibers; A carding process (S200) of arranging the raw materials using a carding machine; A web process (S300) of evenly spreading the processed raw materials in the carding process (S200); A punching process (S400) of punching the raw material processed in the web process (S300) using a needle punching machine to make a felt; A heating step (S500) of melting the low-melting fiber by heating the felt in an oven or a heater; It relates to an eco-friendly funeral tube manufacturing method comprising a; forming process (S600) to make a tube by press-molding the treated felt in the heating process (S500).

That is, the method of manufacturing a funeral tube according to the present invention is macroscopically composed of a raw material mixing process (S100), a carding process (S200), a web process (S300), a punching process (S400), and a molding process (S600).

Specifically, the raw material mixing process (S100) is a process of making raw materials by stirring and mixing 25 to 35 parts by weight of synthetic resin fibers and 60 to 80 parts by weight of low melting point fibers with respect to 100 parts by weight of natural fibers, and preparing raw materials made of felt It is a process.

At this time, it will be replaced by the above description of the specific description of natural fibers, synthetic resin fibers and low melting point fibers mixed in the raw material mixing step (S100), and if the raw material further includes any one or more of a water repellent or jellyfish powder It will be apparent that any one or more compositions of the water repellent or jellyfish powder are further mixed in the raw material mixing process (S100).

In addition, it is preferable that the raw material mixing process (S100) is stirred and mixed so that the mixed compositions are uniformly mixed.

In addition, when the raw material further contains jellyfish powder, the natural fiber and jellyfish powder are first stirred and mixed, and then other compositions are further added and mixed.

In connection with the above, when the natural fiber and the jellyfish powder are stirred and mixed as described above, only the natural fiber and the jellyfish powder may be stirred and mixed, but after a certain amount of water is added to the natural fiber and the jellyfish powder, the mixture is stirred and mixed. Natural fibers and jellyfish powder can be stirred and mixed as a method of drying moisture.

That is, when water is added during the pre-stirring mixing of natural fibers and jellyfish powder as described above, moisture is absorbed by the jellyfish in the powder state, and the mucin component contained in the jellyfish powder is changed to have a certain viscosity, and the jellyfish powder is It is possible to realize the effect of uniformly coating the surface of natural fibers. At this time, the mixture of natural fibers and jellyfish powder mixed with water by stirring may be dried using an oven or dryer to evaporate moisture contained in the mixture.

In addition, the amount of water added when stirring and mixing natural fibers and jellyfish powder as described above can be appropriately adjusted according to the judgment of a person skilled in the art, and is preferably added in the same composition ratio as the jellyfish powder, so that the mixture to be stirred and mixed is too thin or cold. It is desirable to be configured not to lose.

In addition, the carding step (S200) is a step of arranging the raw material using a carding machine, and is a step of unpacking and arranging fibers in a clustered state contained in the raw material obtained in the raw material mixing step (S100).

At this time, the karting process can be performed using a known carding machine, and a detailed description thereof will be replaced with a known technique.

In addition, the web process (S300) is a process of evenly spreading the raw materials processed by the carding process (S200), and is a process of spreading the raw materials processed by the carding process (S200) to have a uniform density. At this time, the web process (S300) can be processed using a known web forming machine, and a detailed description thereof will be replaced by a known technique.

In addition, the punching process (S400) is a process of punching the raw material processed by the web process (S300) using a needle punching machine to make a felt, increasing the twisting of fibers contained in the raw material processed by the web process (S300), It is a process of increasing the mechanical strength of the raw material processed by the web process (S300) by transforming the arrangement of fibers three-dimensionally.

That is, since the raw materials sequentially processed by the carding process (S200) and the web process (S300) have a state in which the fibers are arranged and spread evenly, the degree of twisting of the fibers is small and the mechanical strength is weak. On the other hand, in the punching process (S400), the raw materials processed by the web process (S300) having a state in which fibers are arranged and unfolded are arranged in a two-dimensional manner are punched with a needle punching machine equipped with a plurality of punching needles, and the fibers are as if they are three-dimensional. By allowing them to be twisted as arranged in a row, it is possible to increase the mechanical strength of the felt.

At this time, the needle punching machine may use a known one, and a detailed description thereof will be replaced with a known technique.

In connection with the above, the felt made by processing the punching process (S400) may have a predetermined length through a winding process before being processed in the following heating process (S500) and may have a state wound on a winding roller, and the winding process The felt wound on the take-up roller may be unwound to a required length and then cut to have a length and width sufficient to form a funeral tube, and then subjected to a heating process (S500) below.

In addition, the heating process (S500) is a process of melting the low-melting fiber by heating the felt in an oven or a heater, and applying a certain heat to the low-melting fiber included in the raw material and melting it, thereby melting the natural fiber and synthetic resin contained in the raw material. It is the process of bonding the fibers together.

That is, the low-melting fiber melted in the heating process (S500) is a configuration in which the fibers contained in the raw material made in a felt state are bonded to each other, so that the manufactured funeral tube can have a certain mechanical strength.

At this time, the heat applied to the felt during the heating process (S500) may vary according to the material of the low-melting fiber, and the low-melting fiber is polyethylene terephthalate (PET), polypropylene (PP, polypropylene). Or, if any one or more of polyethylene (PE, polyethylene) is configured, the heating step (S500) is preferably processed for 2 to 5 minutes at a temperature of 160 to 230°C.

In addition, the molding process (S600) is a process of forming a tube by pressing the felt processed by the heating process (S500), and is a process of forming a tube having an inner space in which the body is placed and a lid covered on the top of the tube.

In this case, the molding process (S600) is preferably processed before the felt treated by the heating process (S500) is cooled, and the mold for processing the molding process (S600) has a molding groove having the shape of the tube or lid. It will be obvious that it must be formed.

In addition, the mold of the molding process (S600) may have a state preheated to a predetermined temperature or may be used at room temperature.
