The chorus is also called sericite, and the term 'sericite' comes from the Greek word for silk. It belongs to monoclinic system and has white or off-white pearl luster. Originally referred to as the dominant mineral of crystalline schist rock, especially chorionic schist rock, today it refers to clay-like fine muscovite formed by hydrothermal action. The chemical composition is almost the same as that of the mica, but in general the potassium K is less than the mica and somewhat more water H 2 O. It is produced as a secondary alteration such as feldspar, cordierite, and hongseokseok, and is the most common constituent mineral of feldspar slate or stony rock subjected to light power metamorphism. The potter's stone is caused by the alteration of volcanic rock, which is composed of quartz (70%) and biotite (30%). Cicada is used as a mixing material for ceramics and firebrick, and has various uses such as paints, electrical insulators, active materials, pesticides, and cosmetics.

In order to maintain health and lead a healthy life through the healing methods obtained from nature according to the trend of naturalism and eco-friendliness, sorghum is widely used in the fields of high-quality cosmetics, health care products, and science and technology.

The biotium is rich in dozens of essential minerals and trace elements. It emits far-infrared rays and negative ions to promote metabolism, smooth blood circulation, toxin discharge, clean up waste products, and block harmful electromagnetic waves (vessels). It is the health keeper of modern man who releases healing waves and develops the power to resist diseases by ourselves.

The biotite is a natural mineral having the best far-infrared emission, promoting blood circulation, promoting metabolism, relieving pain, discharging waste and detoxifying the far-infrared effect, healing wave effect for detoxification and disease healing, blood purification and antibacterial anion. Has a deodorizing effect to remove effects and bad body odor

The biotite powder is preferably a powder dyed in the same color as the yarn.

The antoca powder should be prepared by sintering and pulverizing iron-containing clay or loess at a temperature of 600 ~ 1,200 ℃, reddish brown.

The biotite powder is prepared by grinding after heating 15 to 45 minutes at 700 ~ 800 ℃.

The bubble paper 11 is preferably made of a polypropylene nonwoven fabric for stability of the form.

The back coating material 111 is 110 to 120 parts by weight of water, 0 to 100 parts by weight of bicarbonate, 100 to 200 parts by weight of mica wool or antoca, 100 to 200 parts by weight of a viscous agent, 1 to 2 parts by weight of latex or polyurethane thermosetting resin, It consists of a mixture of 1-2 parts by weight of pigment and 0.5-1.5 parts by weight of antioxidant.

The bubble paper 11 in which the yarn is planted is coated with the back coating material 111, dried with hot air at 80 to 120 ° C., and wound up with a winder to produce artificial grass in a roll form.

The biotite is dried for 15 to 45 minutes in the range of 700 ~ 800 ℃ Celsius to remove organic matter, impurities and the like, and then crushed to an appropriate particle size, it is ideal to use the same color as the yarn of grass.

The yarn is usually produced sequentially in the process of raw material injection-mixing-melting-spinning-cooling-stretching-winding.

In order to uniformly mix the durability improving additive and the competition improving additive in the production of the yarn, first, the polyolefin-based resin and mica powder or antoca powder, pigments and additives are mixed to form a masterbatch.

The masterbatch is used for improving productivity and dispersibility.

The master batch is formed by mixing 70 ~ 90% by weight of polyolefin-based resin: 30 ~ 10% by weight of additives (mole mica or antoca, pigments, additives), ideally 80:20 ratio, can be sufficiently blended The mixture is first mixed using a mixer, and the mixture is melted at a temperature of 120 ° C to 170 ° C, extruded through a die, and cut into pellets.

The mixer can be used at both high and low speeds, but a high speed mixer is ideal.

Thereafter, the pellet mixed with the additive formed in the masterbatch and the polyolefin-based resin to which the additive is not added are mixed at a predetermined ratio, thereby sequentially performing melt-spinning-cooling-winding to produce yarn having functionalities. . That is, the melt mixture including these is stretched after extrusion to produce yarn.

Monofilament yarns used for artificial turf are preferably 1-3 mm wide and 70-500 μm thick.

 That is, it extrudes by a normal method and manufactures a yarn. This process is performed sequentially by mixing-melting-spinning-cooling-stretching-winding.

The molten mixture produced by mixing the pellets in which the additives formed in the masterbatch and the polyolefin-based resins without the additives are added at a predetermined ratio is spun through a die having a plurality of nozzles, stretched and wound up after cooling in water, and produced. When this is completed, the melting temperature is in the range of 120 ℃ to 170 ℃ but determines the appropriate temperature according to the material.

By stretching, the tensile strength is improved. The stretching is in the range of 3 to 10 times the original length at 80 to 110 degrees Celsius, and 6 to 8 times is ideal. The heating method is hot air or roll.

The yarn may be molded in the form of fibrillated yarn or monofilament yarn, but is preferably monofilament yarn. Fibrillated yarn cuts the molded product extruded and stretched to a certain width in the form of a film, due to the mixed mica powder in the process of cutting may not be smooth and can reduce the weather resistance.

The yarn thus produced is usually planted in a polypropylene bubble paper by a method such as tufting, laselle, and the like, and then coated with a back coating material 111, which is a thermosetting resin, for drying of the back surface for stability of form and drawing strength of the pile.

Since the back coating material 111 has been described in detail in the process of describing the artificial turf structure, it is omitted from the artificial turf.

According to the artificial turf structure reinforced with the back coating with the functional material of the present invention, the mica has anion and far infrared rays, and has antibacterial deodorizing effect. It is contained in the artificial turf structure to remove odors peculiar to chemicals, so that it is possible to play comfortably, and the user's health is enhanced by the function of far-infrared rays and negative ions. It has the effect of protecting the athlete.
