Description

Pillow Chip Prepared With Polypropylene Resin Composition Containing Quartz Porphyry and Charcoal

Field of invention

The present invention relates to a pillow. More specifically, the present invention relates to a content filled in the interior of the pillow, and relates to a pillow chip and a method for manufacturing the same produced from a polypropylene resin composition containing elvan and charcoal.

Background of the Invention

Pillows are one of the important items in human daily life. Pillows should be particularly suitable for a good night's sleep and should be able to keep the neck comfortable during sleep. Accordingly, various types of pillows have been used so far, and various materials have been developed.

Pillows usually consist of a pillow case and a pillow. The pillow shell is usually made of a fabric such as cotton, and filled with a pillow inside the pillow shell to maintain a constant volume. In the pillow, cotton, synthetic fiber cotton such as polyester and acrylic, fabric pieces, and the like, and grains such as red beans and wood are traditionally used. Recently, pillow chips manufactured by containing functional materials such as ceramics in synthetic resins such as polypropylene and polyethylene have been developed and used in pillows.

The present inventors have focused on the fact that far-infrared rays are very beneficial to the human body, and have developed a method for manufacturing a pillow chip by containing elvan and charcoal, which are substances capable of emitting a large amount of far-infrared rays, in a synthetic resin.

In general, elvan is prepared in a powder state and mixed with a synthetic resin pellet (pellet) can be uniformly mixed. However, it has never been possible to mix charcoal with plastic pellets. The synthetic resin chips with charcoal evenly distributed by mixing charcoal and resin pellets have not been developed until now.

The present inventors have prepared ganbanite containing germanium as a powder, mixed the ganbanite powder and charcoal powder with polypropylene chips, and then melted and extruded them to develop polypropylene chips for pillows containing ganbanstone and charcoal. will be.

An object of the present invention is to provide a polypropylene chip for a pillow containing a mixture of ganban stone and charcoal by mixing ganbanite powder and charcoal powder on the polypropylene chip.

Another object of the present invention is to provide a pillow that can emit a large amount of far-infrared radiation beneficial to the human body by using a polypropylene chip containing elvan and char in the pillow.

Still another object of the present invention is to provide a method for manufacturing a polypropylene chip for a pillow in which powder is uniformly mixed by mixing charcoal powder with polypropylene.

The above and other objects of the present invention can be achieved by the present invention described below.

1 is an infrared ray deterioration measurement photograph capable of measuring far infrared rays emitted from a pillow made of a pillow chip according to the present invention.

Figure 2 is an infrared thermography photograph of a pillow made of a conventional polyester cotton.

The pillow chip of the present invention contains 60 to 87 parts by weight of polypropylene, 10 to 20 parts by weight of elvan, and 3 to 20 parts by weight of charcoal, and an antistatic agent may be added in a small amount. The pillow chip is cylindrical, its diameter is about 5 mm, the length is about 1 cm, the thickness is preferably about 0.7 to 0.8 mm. It is preferable that the elvan is used in the present invention containing germanium, and the germanium content is about 7 ppm.

The pillow chip of the present invention is dried powdered charcoal in a furnace at 60 ~ 70 ℃ for about 2 hours, and put the dried charcoal powder, polypropylene chip, ganban stone powder, and the antistatic agent in the mixer in about 2 hours After mixing for a time, the mixed raw material is prepared by melt extrusion at 180 ~ 200 ℃. The melt-extruded cylindrical extrudate is passed through cooling water to cool, and the cooled cylindrical extrudate is cut to a length of about 1 cm. The elvan powder and the charcoal powder are preferably fine particles of 30 mesh or more. If the particle size is less than 30 mesh or the powder is uneven, bubbles are generated to produce a defective product.

The pillow chip of the present invention is made of polypropylene, elvan, and charcoal, and a trace amount of antistatic agent is added. The polypropylene contains 60 to 87 parts by weight, the elvan is 10 to 20 parts by weight, and the char is 3 to 20 parts by weight. Far greater than 20 parts by weight of elvan is not significantly affected by far-infrared radiation, and when used at less than 10 parts by weight, sufficient far-infrared radiation cannot be obtained. Even if the charcoal exceeds 20 parts by weight, far-infrared radiation is not greatly affected, and when used at 3 parts by weight or less, sufficient far-infrared radiation effects cannot be obtained.

Elvan and charcoal used in the present invention is a powder state having a fine particle size of 30 mesh or more. If the particle size is 30 mesh or less or the powder is uneven, bubbles are generated on the chip surface during the melt extrusion process, which is not preferable.

Polypropylene chips and charcoal powders have never been developed. The reason is that the charcoal powder is incompatible with the synthetic chip and does not mix well. In the present invention, by developing a method for mixing charcoal and polypropylene, it is possible to manufacture a polypropylene chip for a pillow containing charcoal.

In the present invention, first, a charcoal powder having a fine particle size of 30 mesh or more is prepared, and the charcoal powder is dried in a furnace at 60 to 70 ° C. for about 2 hours. By drying in this way it is possible to sufficiently remove the moisture from the charcoal powder to prevent the coalescence of the coal powder due to the moisture. Charcoal can be used in various ways, such as oak charcoal, pine charcoal, oak charcoal called oak charcoal is most preferred.

The dried charcoal powder is placed in a mixer with a polypropylene chip, ganban stone powder, and an antistatic agent and mixed for about 2 hours. When mixed as described above, elvan rock powder and charcoal powder are uniformly applied to the surface of the polypropylene chip in the pellet (pellet) state.

The coated polypropylene chip is melt extruded through an extruder. The temperature of the extruder should be maintained at 180-200 ° C., which is easily carried out by one of ordinary skill in the art of polypropylene extrusion.

The melt-extruded extrudate is cylindrical in shape, which is cooled while passing through cooling water, and cut into lengths in a cutter to produce a chip for a pillow. Pillow chips are manufactured in sizes of about 5 mm in diameter, about 0.7 to 0.8 mm in thickness, and about 1 cm in length.

In the present invention, a small amount of antistatic agent is used to prevent the generation of static electricity. This can be easily carried out by those skilled in the art of polyethylene, and an example of a representative antistatic agent is titanium dioxide (Ti-Pure ™) manufactured by Du-Pont.

The pillow chip produced in the present invention is filled in the pillow skin to produce a final product pillow. Pillows are usually made of fabrics such as cotton, but also made of synthetic fibers such as polyester. Perforated polyester fabrics are preferred to facilitate far-infrared radiation. Of course, a pillow can also be made by partially mixing cotton and perforated polyester fabric.

The polypropylene chip for a pillow of the present invention can produce a pillow that is beneficial to human health by radiating a large amount of far infrared rays from elvan and char components.

The present invention can be further embodied by the following examples, which are intended to illustrate the invention and are not intended to limit the scope of protection defined by the appended claims.
