Below 30% of the yellow soil powder based on raw material is mixed. The yellow soil powder is mesh size of 600-2500.

Description

MANUFACTURING METHOD FOR FIBER USING YELLOW EARTH}

The present invention relates to a method of manufacturing yarns using loess, and more particularly, to a method of manufacturing yarns using loess having various functions such as moisture and insect repellent as well as far infrared rays.

In general, chemical fibers other than natural fibers such as cotton, wool, and silk usually melt a polymer to produce a yarn that is thin while extruding and spinning.

These yarns have been used to make various fibers by blending with natural fibers, but in recent years, it has been made to infiltrate or coat yarns and various minerals to yarns or fibers so as to continuously emit the functionalities of the fibers, such as far infrared rays, which are beneficial to the human body. do.

However, since the addition of ocher or various minerals to the yarn or fiber is soaked or chemically thinly coated in the diluted solution of ocher or various minerals, such as general dyeing treatment after the yarn or fiber is manufactured, The content of various minerals is extremely low, and there is a problem that the effects of far-infrared radiation or moisture-proofing and sterilization are insignificant.

Therefore, the present invention has been invented to solve the problem in view of the conventional problems as described above, to produce a yarn by mixing a large amount of ocher during the manufacture of the yarn to produce the yarn inherent in the function of far-infrared radiation and antibacterial and moisture-proof This is to work very large.

Characteristic implementation method for this is that the yarn prepared by using the ocher powder prepared from raw ocher, first knead finely pulverized ocher powder mixed with the raw material at a weight or volume ratio of 30% or less by about 650 to 2,500 mesh It is produced by melting, extruding and spinning.

Hereinafter will be described in detail the configuration and operation according to the embodiment of the present invention.

First, the ocher of the present invention is put in a rotary kin such as Klin, which is generally used in cement manufacturing, in the raw ocher collected less than about 50 cm from the surface in order to exclude the addition of impurities, in the range of 100-1,200 ° C. It is heated to a temperature and calcined, and then finely powdered to about 150-2,500 mesh using a general crusher, and then the powder is supported and collected using a suction force of a fan to prepare ocher powder.

Here, the firing temperature range of the fresh ocher is a temperature capable of completely removing moisture from the fresh ocher at the earliest time, and in particular, it is preferable to fire at a high temperature to completely remove the foreign matter contained in the fresh ocher.

Such ocher powder has the following characteristics as can be seen in the test report of Korea Institute of Construction Materials.

That is, it can be seen that the deodorizing function of the ocher powder prepared according to the present invention is removed about 95% after about 2 hours in the case of ammonia.

Test Items Elapsed time (minutes) Blank concentration (ppm) Sample concentration (ppm) Deodorization rate (%) Deodorization test Early 500 500 - 30 480 80 83 60 470 50 89 90 450 30 93 120 440 20 95

Note) The blank concentration is measured without the sample (ocher powder).

Sample is 40 x 40 x 10 (mm)

In addition, the ocher powder prepared according to the present invention can be seen that the emissivity of far-infrared radiation is higher at a temperature of room temperature than high temperature.

Measurement temperature (℃) Emissivity Radiation energy (W / m ² ) 40 5-20㎛ / 0.927 3.74 x 10 ² 200 4-20㎛ / 0.916 2.21 x 10 ³ 400 3-20㎛ / 0.892 9.23 x 10 ³

Note) Sample is ocher powder

This is the result of comparing Black Body using FT-IR Spectrometer.

The yarn manufactured using the loess powder prepared from the raw loess as described above is first manufactured by mixing, kneading, extruding and spinning the loess powder finely crushed to about 650 to 2,500 mesh with the raw materials, and then the weight of the loess powder. The volume ratio is less than 30% and is mixed with raw materials.

Here, the raw material is a polymer such as polyester and nylon, plastic and acrylic.

That is, after mixing less than 30% ocher powder, the ocher powder prepared according to the present invention, 70% or more raw materials, the mixture is heated to prepare a molten state of liquid, but to make the molten state The temperature varies depending on the type of polymer that is the raw material used and has a temperature range of approximately 115 to 315 ° C.

Subsequently, the molten polymer mixed with ocher is extruded and spun using an extruder to produce yarn, which is extruded and spun into a long or short length as necessary.

In this way, long or short yarns are woven together with silk, cotton, or wool to make synthetic fibers to produce a variety of products, such as clothes and underwear, beddings such as duvets, and pads for health care. In addition, the large amount of loess contained in these products not only emits far infrared rays but also maintains antibacterial and bactericidal activity.

As described in detail above, the present invention provides a continuous and large amount of clothing or acupuncture and health aids manufactured using yarns in which clay particles of fine particles are mixed with raw materials of polymers at an appropriate ratio by heating and drying raw clay. Of course, the far-infrared radiation of the antibacterial, sterilization, deodorizing action, so that when used or used it will always have a pleasant feeling.

In addition, as the ocher powder is mass-produced by a heating and drying method, the ocher powder manufacturing cost can be greatly reduced, thereby reducing the manufacturing cost.
