Description

A manufacturing method of man made fiber using clay mineral}

The present invention is a method of manufacturing artificial fibers that are natural-friendly and contribute to the beneficial functions of the human body by the addition of clay minerals.In more detail, ilite powder that is given desired efficacy while recycling wastes that are exhausted on a one-off basis By adding more, etc., it not only actively reduces the waste of resources, but also helps maintain health such as far-infrared radiation effect, deodorization, antibacterial effect, generation of negative ions, air purification, electromagnetic and water vein waves blocking, etc. Furthermore, it relates to a method of manufacturing a clay mineral-filled artificial fiber that also exhibits a function as a non-combustible material.

When weaving a variety of fabrics as polyester fibers, a large amount of wrinkling occurs, and although these wrinkling yarns are recycled, most of them are discarded, and PET bottles are also almost discarded rather than recycled.

Since polyester waste is mainly treated by incineration or landfill, it acts as a major cause of environmental pollution such as air pollution and soil pollution.

In addition, depending on the amount of the polyester fiber and PET bottles to be discarded, it may act as a factor of increasing the manufacturing cost. Therefore, if the waste and PET bottles are effectively recycled, environmental pollution such as air pollution or soil pollution is more prevented. In addition to actively preventing it, it is also possible to prevent wasting valuable resources.

On the other hand, illite is known as an off-white, green synthetic mineral as its main components are SiO2, Al2O3, K2O, MgO, and Fe2O3, whose mineralogical structure has a lobe-like clay structure. These illites emit 90% or more of far-infrared rays with a wavelength of 3-25 microns at room temperature to emit a large amount of wavelengths that are beneficial to the human body, deodorize or neutralize various odors and odors, and have antibacterial and sterilizing effects of various bacteria. It is known to be excellent in generating strong negative ions, moisturizing effect, blocking direct ultraviolet rays, and shielding various harmful wavelengths such as water vein waves and electromagnetic waves. Recently, various products or methods of using illite by adding or using ilite Etc. are being researched and produced.

As another clay mineral, pearlite is emerging, and such pearlite is also actively used in various industrial fields.

As an example of perlite-related technical cases, Patent Publication No. 10-1901726, "Method of manufacturing lightweight building materials using perlite," is published, and the technology is self-developed to compensate for the shortcomings of the moisture absorption properties of the pearlite component. It is a technology in which a ceramic binder is mixed. The ceramic binder is prepared by adding sodium silicate to the ceramic powder and inducing a copolymerization reaction while heating to obtain a composite oxide, pulverizing the composite oxide, and stirring the nano silica sol and distilled water.

As another example of the technical cases of pearlite, Korean Patent Publication No. 10-2016-0126400 "Insulation Panel Using Expanded Pearlite" is published, and the technology relates to a sandwich panel in which pearlite is filled inside of an insulating material, With the passage of time, pearlite moves downward by its own weight, forming an empty space inside, and in order to overcome the problem of losing its function as an insulating material because the heat insulation function is excluded in the space, the heat insulating gas is injected into the space. It is a technology that filled balloons.

[Artificial fiber manufacturing process]

1st process: polyester parsing and PET bottle Mixing process

A large amount of polyester waste (polyester parse and PET bottle) is collected and pulverized by putting it into a grinder. After 5-7 minutes have elapsed after the input, it is pulverized while adding water to form chips.

At this time, water, salt, and phytoncide may be added while pulverizing the polyester waste, and further, a predetermined pearlite powder must be added together with the illite powder.

In the above, the pearlite powder is processed into a panel shape having a porous surface and then simultaneously pulverized with polyester waste. When mixing with water, salt and phytoncide, when mixing with water, salt, and phytoncide, the bonding strength increases according to the crystal shape of the chip and contributes to weight reduction.

2nd process: drying and Illite Powder addition process

The polyester parsers and the crushed chips of PET bottles made in the first process are put into a friction dryer to dry, but when the temperature of the rotating friction dryer is about 100 to 120°C, the polyester parsers or the crushed chips of PET bottles (chip) Add about 01~05% of wax and about 2~4% of illite of 1000~10000 mesh and rotate until the temperature reaches 165~175℃.

The wax added in this process acts as a binder for bonding the crushed chips and illite powders of the polyester and PET bottles and lubricating them.

3rd process: drying and forming process

Put illite and pearlite powders added from the dryer into an extruder and melt-spinning the chips (semi-solid state) of the PET bottle into the extruder, and the spinning process → the maritime process (sealing while adding water) → Drawing process → After going through the crimping process (the process to make it very winding), drying and setting between 135 and 140℃ → cutting → completion (packaging).

[Non-woven fabric manufacturing process]

In the same state as the artificial fiber manufacturing process, the first process (polyester parsing and PET bottle mixing process, pearlite addition process) and the second process (drying and illite powder addition process), illite powder from the dryer is added. Polyester parsing and PET bottle chips (semi-solid state) are put into an extruder and melt-spinned to make staple fiber (SF). → Needle Punching → Selvage Cutting → Winding → Completion (packaging).

At this time, water, salt, and phytoncide may be added while pulverizing the polyester waste, and a predetermined pearlite powder must be further added together with the illite powder, as is well known.

In the above, the pearlite powder is processed into a panel shape having a porous surface and then simultaneously pulverized with polyester waste. When mixing with water, salt and phytoncide, when mixing with water, salt, and phytoncide, the bonding strength increases according to the crystal shape of the chip and contributes to weight reduction.

Examples of the present invention in this regard are as follows.

[Step 1]

About 100 kg of polyester bottles and parsers were put into a pulverizer and pulverized finely, and after about 6 minutes had elapsed, pulverized and mixed while sprinkling water to form chips. Water, salt, phytoncide, and perlite were added in a certain amount.

[Step 2]

In the process of drying by putting the chips made in the first process into a friction dryer that works while rotating, when the temperature reaches 115°C, about 100 g of liquid wax and 400 g of illite powder sieved through a sieve of 1000 to 10000 mesh are added. The friction dryer was rotated to 170° C. while mixing and mixing.

[3rd step]

The PET bottle and polyester parsing chips formed in the second process are put into an extruder and spun while melting. It was completed by cutting it into sized fibers.

After going through the first and second processes as in the above artificial fiber embodiment, the PET bottle and polyester parsed chips are put into an extruder and spun while melting, making them into a staple fiber (SF) state, and then opening them → kneading → somen → contact layer An appropriate web was formed through (Cross lapping), needle punched to bind the web, and then the edge part was cut to size and wound up to complete it.

1 is a flowchart sequentially listing a manufacturing process of an artificial fiber constructed according to a preferred embodiment of the present invention.

As shown in Figure 1, the artificial fiber of the present invention is formed by mixing pearlite powder with a binder to form a set shape (S100); and, using a foaming agent, the porosity provided with a set depth on one side of the panel is obtained. Forming the surface processing step (S200); And, a panel post-treatment step (S300) of firing the panel under a set temperature condition; consists of.

The panel forming step (S100) includes a main material preparation step (S110) of preparing a pearlite material; and a submaterial addition step (S120) of obtaining a molding raw material by adding a binder to the main material; and, a molding raw material using a mold apparatus. It consists of a shape processing step (S130); divided into.

The main material preparation step (S110) is a step in which a pearlite ore is put into a ball mill device, and a repetitive pulverization operation is performed to obtain a predetermined particle size. For example, the ball mill device proposes any one of a pulverization method of a solid phase method, a liquid phase method, and a gas phase method, and in the present invention, it is possible to manufacture high-purity pearlite powder while lowering the manufacturing cost compared to the solid phase method and the gas phase method, and The liquid phase method, which is easy to control the size, was adopted as a preferred embodiment.

The subsidiary material addition step (S120) is a step of adding and stirring a viscous binder to the pearlite powder, and a kneader is used for a uniform stirring operation. The pearlite powder and the binder are sequentially added to the kneader and then stirred to induce the particles between the powders to occlude, thereby actively improving the precision of the shape during mold processing.

The shape processing step (S130) is a step of forming a molding material into a shape of a finishing material using a mold device, and a molding part manufacturing step (S131) of arranging a molding space in the mold device and then placing the molding space in the mold device (S131); And, the molding part is formed in the molding part. It consists of; a molding raw material charging step (S132) of charging the raw material; and a molded body molding step (S133) of pressing the molding raw material with a mold (S133).

The mold apparatus used for the molding operation in the shape processing step (S130) includes all equipment capable of processing into the shape sought by the operator regardless of the type such as the pressurization method and the injection method, but preferably, the excellent performance of pearlite is achieved. A Wet Process Cold Isotropic Pressure (CIP) method that can be actively preserved is adopted as a preferred embodiment.

The wet CIP method can obtain a panel with positively improved durability as well as a precise shape from a uniform density and high pressure molding pressure due to the characteristics of a processing method in which all six surfaces of a raw material injected into a rubber mold are pressed. Here, the wet CIP device is a device that pressurizes by immersing the powder in the rubber mold and then immersing it in the liquid in the molding container. The pressure provided by the pressure port is in a state where the upper and lower opening ends of the mold are completely closed with the covers of each part. It is a structure in which the molded powder charged into the rubber mold is molded into a preset shape by the isostatic pressure method, limited to the required molding pressure through the medium. At this time, the pressure axial force is received by the press frame, and after pressure molding, the pressure medium is discharged from the pressure port to reduce the pressure to atmospheric pressure, and final molding is performed.

The molding part manufacturing step (S131) is a step of creating a molding part in a shape corresponding to the outer shape of the finishing material in the mold. Here, the mold is a part filled with resin and solidified to prevent deterioration or failure due to moisture or vibration. It has a purpose and is characterized by using a mold resin such as polyester. In particular, in the present invention, an elastic mold made of rubber, silicone, etc. is used, and the reason is that the elastic mold has the advantage of being resistant to temperature, simple precise molding, and easy separation of the molded product after the molding operation.

The molding raw material charging step (S132) is a step of charging the molding raw material to the molding part in which the mold is formed, and the molded body molding step (1S33) is after adding a stabilizer composed of _{yttrium trioxide (Y 2} O _{3) to the molding raw material.} It is a step of press-molding at a pressure of ~150 MPa.

The surface processing step (S200) is a step of forming a porous surface roughness on the surface of the panel, preferably forming a porous surface roughness on one of both surfaces of the panel.

The method of expressing the surface roughness using the foaming agent proposed by the present invention consists of a foaming agent manufacturing step (S210) of first generating a foaming agent, and a porosity forming step (S220) of forming porosity by applying the foaming agent to the surface of the panel.

The foaming agent manufacturing step (S210) is a mixed solution of pearlite powder, carbon powder, and water. The pearlite solution melted by water is bubbled by the carbon powder.

The porosity forming step (S220) is a step of forming porosity on one side of the panel using the foaming agent. In the present invention, a method of forming porosity on its own surface of the panel and attaching a separate porous member to one side of the panel Suggest a method.

The method of forming porosity on its own surface is a method of forming a porous surface by spraying a foaming agent onto the surface of the panel. In the process of discharging the foaming agent from the nozzle, the carbon powder acts by the discharge pressure to form air bubbles. Adsorption/penetration into the surface and the interior of the panel erodes part of the surface, thereby forming a plurality of craters of irregular sizes and shapes.

The method of attaching the porous member to one surface of the panel is a method of realizing a porous surface on the corresponding surface of the panel by attaching a porous member having a porous surface on one surface of the panel with an adhesive and integrating it.

The porous member attachment method is a step of generating a porous layer raw material (S221) in which a foaming agent is added to sodium hydrogen carbonate powder and then stirred to obtain a porous layer raw material; And, after loading the porous layer raw material into a molding machine, it has a shape corresponding to the finishing material. Forming the porous member forming step (S222); And, the porous member bonding step (S223) of integrating by bonding the porous member to the finishing material using an adhesive for building materials; consists of.

In the porous layer raw material generation step (S221), sodium hydrogen carbonate powder is a fire extinguishing powder commonly filled in a fire extinguisher, and was adopted as the main material of the porous member in order to impart non-flammable and fire extinguishing functions in the event of a fire.

In the step of forming the porous member (S222), the carbon powder of the foaming agent reacts by the pressing force of the molding machine in the process of forming the porous layer raw material, thereby generating a plurality of bubbles of various sizes at unspecified locations, thereby forming a porous surface.

The porous member bonding step (S223) is a step of bonding the porous member to the finishing material using an adhesive and integrating it, and does not limit the bonding location and the type of adhesive used for bonding.

As a result, the perlite material has been given porosity in order to be more efficiently combined in the process of being implemented in the form of a chip. Accordingly, the artificial fiber or non-woven fabric can achieve a level that satisfies all of ultra-lightweight, thermal insulation, non-flammability, and discoloration prevention. It is done.

The panel post-treatment step (S300) is a step of forming a porous surface on the surface of the panel while oxidizing air bubbles partially penetrating into the surface and inside of the panel, that is, carbon powder while firing the panel, wherein the panel to which the foaming agent is applied is formed from 1200 to By heating at 1800° C., the carbon powder is oxidized to a concentration of 10 to 40 wt% to form a porous surface.

Meanwhile, the carbon powder formed on the surface of the panel is rapidly oxidized by firing heat to form craters. In this oxidation process, fine cracks are generated on the surface of the crater. The cracks degrade the external quality of the panel and, although at a fine level, cause problems such as reducing the durability of the panel. At this time, the pearlite powder mixed with the foaming agent penetrates into the space and completely fills in and reinforces the crack.

According to the present invention having the above-described configuration, not only recycled polyester wastes (polyester waste discarded in yarn manufacturing factories, textile manufacturing factories, etc., and all PET bottles as industrial waste) are recycled to generate recycled fibers, as well as to exhibit scavenging functions. By adding more contributing illite or pearlite powder to manufacture all kinds of fibers and non-woven fabrics, waste of valuable resources is suppressed, and due to various beneficial effects of clay minerals, far-infrared radiation effect, deodorization, antibacterial effect, generation of negative ions, air purification It is more effective because it exhibits a function as well as a function as a non-combustible material, as well as an ultra-lightweight or thermal insulation function, as well as a blocking effect of electromagnetic waves and water vein waves.

The present invention described above has been described with reference to an embodiment shown in the drawings, but this is only exemplary, and various modifications and other equivalent embodiments are possible from those of ordinary skill in the art. Should be clarified. Accordingly, the true technical protection scope of the present invention should be interpreted by the appended claims, and all technical ideas within the scope equivalent thereto should be construed as being included in the scope of the present invention.
