The present invention relates to a method for producing polyester fiber mixed with loess, and more particularly, to supply the loess powder processed into fine particles directly to the main extruder together with the dried polyester chip to spin through a process such as melting / mixer. It relates to a method for producing a polyester fiber mixed with loess to be.

 As is well known, ocher covers about 10% of the earth's surface and is largely a deposit of silt-sized particles with a diameter of 0.002 to 0.005 mm and has a large amount of calcium carbonate (CaCo3).

Due to this calcium carbonate, loess has a viscous force that is not easily broken, and it turns into clay when water is added. It consists of silica (SIO2), alumina (Al2O3), iron, magnesium (Mg), sodium (Na), and kali.

The composition of ocher in Korea is somewhat different depending on the region, but generally silicon (Si) is 48%, the most is aluminum (A1) 35%, iron (Fe) 11%, magnesium (Mg) 6%, etc. to be.

Ocher composed of such a ratio and various enzymes emits a large amount of far-infrared rays necessary for the growth of animals and plants, so it is called a living organism.

Ocher is a honeycomb structure with a large surface, and a large number of spaces have a multi-layer structure.

In this sponge-like hole, far-infrared rays are absorbed and stored in a large amount, and radiate when heated to stimulate molecular activity of other objects. In other words, loess absorbs solar energy for many years and can be called 'solar storage' simply as silicon mineral.

The loess, which covers 10% of the earth's surface today, is semi-arid and widely distributed in the region.

A spoonful of ocher contains about 200 million microorganisms, causing various enzymes to circulate. Since ancient times, ocher has been used as a living creature, a disease-free long-lived soil with great weakness. Korea's ocher is composed of yellow sand that has flown hundreds of thousands of years from mainland China.

The enzyme component of loess includes four types of catalase, diphenol oxidase, saccharase and protease. Each of these enzymes plays a role in detoxification, degradability, fertilizer components and purification.

The natural energy of loess, such as far-infrared rays generated from loess, is very beneficial to the human body as the life force.

It acts to neutralize lipid peroxide, which is a bad poison in the human body. It is ph8.5 ~ 9.5, which is close to neutral and harmless to human body.

Ocher absorbs moisture when the humidity is high, and it emits moisture when it is dry. It has excellent automatic humidity control (compatibility), and its absorption rate is high as 20 ~ 25%.

It prevents the heat outside and radiates warmth when the weather is cold.

Due to the small pores in the ocher particles, it acts as a ventilator to circulate the air, as well as an air purifier, and blocks harmful electromagnetic waves by a large amount of far-infrared radiation.

As such ocher is known to be beneficial to the human body, functional products using ocher are being developed and marketed, and the scope of application is diverse.

Conventionally, the above applications using ocher include fibers containing ocher, and methods related to providing the ocher containing fibers have been described.

However, among the methods for providing the fiber containing the ocher, the illite powder dried and the polypropylene chip dried are mixed and introduced into an extruder to prepare a master batch chip by extrusion / cooling / cutting, and the master batch chip and the polypropylene chip. It was dried to put in the spinning machine, spinning / stretching / gripper / drying / cutting to prepare the illite fiber.

In this method, the illite powder and the polypropylene chip are mixed and introduced into an extruder to produce a master batch chip by extrusion / cooling / cutting, and then the master batch chip is introduced into a spinning machine together with the polypropylene chip at a predetermined ratio to produce fibers. Because it can be obtained, the work process is very complicated, cumbersome, and there is a disadvantage that the cost of the fiber is formed very expensive by the equipment and many work processes accordingly.

In addition, the fiber quality could not be satisfied under the conditions of producing fiber products, especially because the illite powder could not be supplied while maintaining the proper temperature. There was a problem such as deterioration.

An object of the present invention for solving the above problems is to put the ocher powder processed into fine particles (5000 ~ 7000 mesh) directly into the main extruder with the dried polyester chip to be immediately radiated through a melt / mixer, etc. , To shorten the manufacturing process of the polyester fiber mixed with ocher, to maximize the efficacy of the ocher, and to improve the economics such as reducing labor costs, and at the same time to make the spinning conditions suitable for mixed spinning polyester fiber mixed with ocher The purpose is to improve the functionality and quality of the product.

In order to achieve the above object, a method for producing polyester fiber mixed with loess of the present invention is to first feed the loess powder processed into fine particles into a binder dryer in a batch type and to dry it while maintaining a constant temperature through a heat insulating hopper. Feed to the extruder and back to the melt of the main extruder,

Meanwhile, the ocher powder and the polyester chip supplied through the above process are introduced into the main extruder through crystallization / dehumidification drying / hopper dehumidification drying, and the polyester chips are spun through melting and mixer. If described in detail as follows.

1 is a fiber manufacturing process according to the present invention.

1st process

The loess collected from the field is processed to prepare the loess powder of fine particles 5000 ~ 7000 mesh, and it is put into the blender by batch type, and it is maintained and dried at 200 ~ 230 degrees for 4 ~ 5 hours to feed feeding extruder. (At this time, if the ocher is not completely dried, it will be cut during spinning, so it is important to keep the ocher powder dry.)

2nd process

The polyester chip is dried at 170 to 185 degrees for 4 to 5 hours in a dehumidifying dryer. At this time, the polyester chip dried at a moisture content of 5 ppm or less is put into a hopper dehumidifying dryer in a continuous method.

3rd process

6 to 10% by weight of ocher powder obtained in the first step and 90 to 94% by weight of polyester chip obtained in the second step are introduced into the main extruder and melted and mixed with each other, and compressed, filtered, improved and hollow nozzles are used. Radiate. And a cooling process and winding to obtain a polyester fiber mixed with ocher.

When the ocher powder is supplied to the molten part of the main extruder, a certain amount is supplied by RPM improvement.

The spinning condition is the spinning temperature is 220 ~ 270 degrees, spinning speed 350 ~ 500m / M, wind speed 2000m / m / sec, the fiber denier is 3 ~ 30 denier polyester fiber mixed with very high quality loess Was produced.

The polyester fiber obtained by the above method is mixed with ocher, and processed by ocher to supply the ocher powder of fine particles 5000 ~ 7000 mesh to the feed extruder through a heat-insulated hopper to be dried in a binder dryer and maintained at a constant temperature. Feeding through the feeding extruder to the molten part of the main extruder to enable the mixed spinning of inorganic loess and organic polyester, so melted / mixed with the polyester chip immediately while spinning through compression / filtering / improvement / hollow nozzle Can be.

Therefore, it is possible to shorten the production process while maximizing the efficacy of the loess, thereby improving workability and at the same time gaining economic benefits.

According to the manufacturing method of the polyester fiber mixed with the loess of the present invention as described above, it is possible to reduce the heat loss during the manufacturing process and to shorten the manufacturing process to improve the labor cost and the economy accordingly, and also the very good quality loess Since it is possible to obtain a blended polyester fiber, it is an invention that has the effect of meeting the needs of consumers and leading the competition.
