Description

The processing method of the synthetic fiber contaning charcoal powder}

The present invention relates to a method for producing synthetic fibers containing charcoal powder, and more particularly, to a method for producing synthetic fibers containing charcoal powder, which enables the production of synthetic fibers by mixing charcoal powder with synthetic resin.

Conventionally, the charcoal that has been widely used around us is a hardwood such as oak, birch, etc. grown in regions with four seasons including cold winter below minus 20 ℃ in the traditional charcoal kiln baked at 800 ℃ or more.

Such charcoal has been commonly used as a fuel for cooking and heating, and in recent years, it is also used as a grilling charcoal ribs in restaurants and the like, and has been closely related to our daily life.

In addition, charcoal was used for the purpose of ripening food or to remove odors and various germs, and if the charcoal is placed inside a warehouse with grain, it provides humidity control to prevent the corruption of the grain and breeding of insects. Charcoal was also used to prevent decay and odor of the body.

For agriculture, charcoal and ash were used to improve the soil and to protect wheat grains from pests.

As mentioned above, it is known that charcoal has electromagnetic characteristics and emits far infrared rays in recent years.

First of all, the electromagnetic characteristics of charcoal are charcoal, which is a special carbide made of hard wood as a raw material, and wood carbide is a good conductor of electricity. The charcoal, which is such wood carbide, has a higher conductivity as the wood of the raw material is harder and treated at a higher temperature, and thus, the storage capacity is higher.

In particular, charcoal is made to have a strong negative charge around its unique capacity, when a large amount of char is formed in the surrounding environment is a high magnetic field due to negative charge.

The high gasoline created from char is negatively charged through underground and above ground. Generally, in positively charged environment, all materials tend to be rapidly fermented, decomposed, worn, burned and oxidized, but in negatively charged environment, The effect is that the original state is preserved longer and the ecology of the organism is kept in its natural state.

In the underground, charcoal suddenly rises the earth potential after 1 to 3 years, and continues to rise slowly over the next several years. The effect of potential rise lasts about 10 years. Once created, the field is very stable, semi-permanent, and improves the field energy in harsh environments with strong field energy.

As described above, charcoal positively changes the surrounding environment by the characteristics of a unique electromagnetic field, helps with circulatory, respiratory and nervous system disorders, and is effective in fatigue, insomnia, stress and neurological diseases.

Another characteristic of charcoal is that it emits far infrared rays. It emits far-infrared rays to catch the health rhythm, relieve muscle fatigue, and have a clear mind.

As described above, due to the amazing effect of charcoal, research using charcoal is being actively made.

Registered Utility Model Registration No. 129897 and 129898 are registered charcoal mattresses and charcoal pillows.

The mattress with charcoal registered in Korean Utility Model Registration No. 129897 is equipped with charcoal in the mattress so that the charcoal can take a pleasant and healthy sleep due to the effect of electromagnetic field energy on the human body, and sweat released from the body during sleep. Absorbs secretions hygienically to prevent the occurrence of odors and pathogens, and because of the storage capacity of charcoal, which can save heat for a long time in winter, and introduces a mattress that can maintain warmth without using a separate heating device. Doing.

The charcoal-embedded pillow of Republic of Korea Utility Model Registration No. 129898 has charcoal embedded in the pillow to allow you to have a pleasant and healthy sleep due to the effect of the electromagnetic field energy on the charcoal, and sweat released from the body during sleep. It introduces pillows that absorb hyaluronic acid hygienically to prevent the occurrence of odors and pathogens so that you can feel comfortable.

In addition, in the method of manufacturing jade powder coated fiber disclosed in Patent No. 95-9496 and the method of manufacturing a filament impregnated with jade powder registered in Patent No. 151794, a method of manufacturing fibers or filaments using jade having a similar effect to charcoal Presenting.

Techniques for producing jade powder-coated fibers, disclosed in US Pat. No. 95-9496, disclose the preparation of fibers in which a powder of jadeite, commonly known as jade, is adhered to the surface of a yarn by an adhesive.

The technique for manufacturing filaments impregnated with jade powder, which is registered in Korean Patent No. 151794, is a method of preparing filaments impregnated with neat jade powder in the form of synthetic fibers. It proposes a method for producing a filament that allows the uniformity of the filament to be incorporated into the structure of the filament, thereby exhibiting the characteristics of purgatory.

However, agitation is easy due to the large specific gravity of jade in the production of synthetic fibers using jade, etc. However, when using charcoal, the specific gravity of the charcoal causes a problem in that the charcoal is scattered. Due to the problem of scattering of charcoal powder, the content of charcoal in the synthetic fiber produced during the production of the synthetic fiber is not constant, and also the problems such as lowering the working environment.

The present invention is to solve the conventional problems as described above, while effectively preventing the scattering of the charcoal powder generated in the synthetic fiber manufacturing process using charcoal charcoal powder is uniformly prepared by mixing the synthetic fibers inherent It is to provide a method for producing a synthetic fiber containing charcoal powder to maintain a characteristic.

In order to achieve the above object, charcoal powder is mixed with DOP (Dioctyl phthalate) oil to form a dough, put into a molten lattice with a polyester resin chip, and then melted. A first step of extruding the synthetic resin using an extruder and then cutting the resin into a suitable size; In the process of melting the polyester resin chip and transporting it to the spinning pump through the screw, the melt made from the first process and transported to the spinning pump through a separate screw and crosses at one part just before spinning to the spinning pump The transferred and transferred polyester resin chip melt and the melt of the polyester resin chip containing charcoal are discharged together by a spinning pump, which is discharged through a filter bag, a cooling tube and a spinning tube, and then stretched. It relates to a method for producing a synthetic fiber containing charcoal made of a secondary step of winding the winding machine through the process.

Hereinafter, the manufacturing process of the present invention will be described in detail with reference to the accompanying drawings.

1 is a flow chart showing a manufacturing process for producing a synthetic fiber containing charcoal powder according to the present invention.

In the first step, the charcoal powder (1) is mixed with the diop oil (2) to form a dough, and put together with the polyester resin chip (3) in the fused lattice (4) at 260 ℃ to melt. At this time, the content of charcoal powder is put to about 40% by weight. The molten charcoal-containing resin is extruded using an extruder (5), and then cut into appropriate sizes to make chips (6) containing charcoal powder.

Diopioil (2) used in the manufacture of chips (6) containing charcoal powder is kneaded by adding 0.02% by weight of the total weight of charcoal (1) as one of the plasticizers generally used in the production of synthetic resins.

Moreover, since melting | fusing point of a polyester resin is about 260 degreeC, the polyester resin chip 3 is melt | dissolved by making the temperature of the melting lattice 4 into 260 degreeC.

The reason for the content of the charcoal powder (1) to be about 40% by weight is that if the content of the charcoal powder (1) is too high, it does not mix well with the melt of the polyester resin chip (3). It is difficult to produce, and if the content of the charcoal (1) is too low, it is easy to blend, but takes a lot of polyester resin chips (3), there is a problem that it is difficult to control the charcoal content of the fiber produced.

Unlike ordinary fiber manufacturing process, the charcoal powder (1) is not put in the stirring process, and the charcoal powder (1) is used for making chips (6) containing charcoal powder. This is because the charcoal is blown in the process of stirring due to the same specific gravity and low, and the char content of the manufactured synthetic fiber is not constant.

In the second process, the polyester resin chip 3 'is melted to form a melt 7 and transferred to a spinning pump 9 through a screw. It melts and crosses at one part just before spinning with the melt 8 of the chip containing charcoal, which is transferred to the spinning pump 9 through a separate screw, and is transferred to the spinning pump 9.

The transferred polyester resin chip melt 7 and the melt 8 of the polyester resin chip containing charcoal are discharged together by the spinning pump 9, and the discharge is carried out by the filter bag 10, the cooling cylinder ( 11) and after winding through the spinning cylinder 12, the winding 13 is wound around the winding machine 14 through a general process of stretching (13).

Polyester resin chip 3 'and resin chip 6 containing charcoal powder are melted, transferred to the intersection, and mixed, that is, the time required for stirring, which is a process just before spinning, is about 40 minutes. Suffice. However, when stirring the polyester resin chip (3 ') and the charcoal (1) in the first step in the general manufacturing process, 350 to 450kg should be stirred for 3 to 4 hours.

In addition, the polyester resin chip melt (7) and the melt (8) of the resin chip containing the charcoal powder is intersected and transferred to the spinning pump (9) containing the polyester resin chip melt (7) and charcoal powder The melt 8 of the resin chip is spun at a ratio of about 9: 1 so that the total charcoal content is 2 to 7% by weight.

The reason that the content of charcoal powder is 2 to 7% by weight is that when the charcoal content exceeds 7% by weight, the thickness of the fiber is not constant in the case of synthetic fibers containing charcoal powder, and the hole of the filter bag It is difficult to work because it is not blocked by spinning, and there is a problem that the char content of the manufactured fiber is not constant. If less than 2% by weight, the thickness of the fiber is constant, but easy to work, but there is a problem that the charcoal content of the manufactured product is too small to maintain the characteristics of the charcoal.

In addition, as described above, the resin chip 6 containing the charcoal powder made in the first step is added during melting of the polyester resin chip 3 'during the second step, and the reason for attaching a separate screw without stirring is as follows. Preventing charcoal powder from drying out during agitation while keeping the charcoal content of the spun fiber constant by adding a desired amount through a separately attached screw, as well as allowing the charcoal to be evenly contained. For sake.

Hereinafter, the present invention will be described through Examples and Test Examples.
