Description

Manufacturing method of bedding batting {a making method of bedclothes emitting an anion}

The present invention relates to a method for producing a bedding cotton, more specifically, the mica (雲母) powder is included in the bedding cotton, which is a characteristic of the mica powder that emits far infrared rays and anions in a natural state, air cleaning, humidity control, thermal insulation It relates to an invention that can improve the health of the user by the effect of deodorization, and the like.

In general, bedding cotton is composed of bedding, yo, pillows, etc. necessary for sleeping, the inside of the bedding is a cushion material that softens the body is embedded.

Our ancestors used cotton swabs from cotton, but cotton swabs are not only complicated processing methods but also take a lot of time and lack of supply compared to demand. Cotton made of synthetic fibers such as vinyl polypropylene is produced and widely used.

However, the above-mentioned synthetic fiber cotton was not able to give a beneficial function to the human body as compared to cotton cotton, so it could not be expected to play a role to improve the health of the user.

Therefore, in order to overcome the various exercise therapy, diet, health water wave and electromagnetic wave shielding material, ocher mat, ocher bed, stone bed, loess is added to the fiber yarn to make a yarn, weaving and use a number of products, etc. Commercialized and flooded.

However, these functional products were used only for one purpose, and they could not expect the antibacterial and bactericidal action of pathogens harmful to humans such as bacteria or bacteria, and they could not absorb or deodorize or decompose odors. The effects of health promotion such as fatigue recovery and blood circulation could not be expected.

The present invention has been made in view of the above problems, the object of which is the characteristics of the mica powder to emit far-infrared rays and anions in the natural state, including the mica powder in bedding cotton, air cleaning, humidity control, thermal insulation, It is to provide a method for producing a bedding cotton that can improve the health of the user by the effect of deodorization.

A feature of the present invention for achieving the above object is the step of collecting the illite which is a monoclinic mica group mineral present in the natural state as a natural mineral; An elite mineral composed of 50 to 54% by weight of silica sand, 35 to 39% by weight of mica and 9 to 11% by weight of chromite was crushed into coarse particles to remove impurities, and then introduced into a drying furnace to heat 700 to 800 ° C. Completely drying the moisture contained in the mineral while being added; Milling the dried mineral finely and filtering it into a fine powder with a sieve having a particle size of 1,000 mesh or more; Precipitating the mineral powder in clean water and stirring it evenly; If the heavy silica sand and chromite are sinking and the light gravity mica is located on the top layer, discarding water and extracting mica; The dried mica is dried and evenly mixed with silver nanopowder having a concentration of 10 to 100 ppm and a size of 1 to 10 nm, but mixed at a mixing ratio of 88 to 92 wt% of mica powder and 8 to 12 wt% of silver nano powder. ; The evenly mixed powder is mixed at a ratio of 3 to 7% by weight with respect to the polyester powder for fiber production, and the evenly mixed raw materials are introduced into an extruder, heated to a temperature of 180 to 240 ° C, melted, and extruded with a screw. Producing a monofilament by spinning with spinnerets having a size of 1.5 to 2 deniers; Stretching and weaving the monofilament to be achieved by a method for producing a bedding cotton, characterized in that it comprises the step of producing a multifilament-like cotton.

The bedding stuffing cotton of the present invention completed by the above-described manufacturing process can promote the blood circulation of the user by anion and far-infrared ray emission effect emitted from mica, as well as to improve the health of the mica and nano silver has strong antibacterial and sterilization By suppressing the growth of mites parasitic to bedding and various germs harmful to human body, sterilization can lead to more hygienic life, and it can absorb and remove irritating odor such as sweat smell. There is an advantage.

Hereinafter, described in detail by the accompanying manufacturing process drawings for a preferred embodiment for achieving the above object is as follows.

Example

The illite, a monoclinic mica group, which exists as a natural mineral in nature, was collected.

The said illite collected the mineral which consists of 50-54 weight% of silica sand, 35-39 weight% of mica, and 9-11 weight% of chromite.

Subsequently, the elite mineral was crushed into coarse particles to remove impurities, and then charged into a drying furnace to completely dry the moisture contained in the mineral while applying heat at 700 to 800 ° C.

In this step, the crushed mineral particles are selected, washed with water, and then naturally dried to further remove fine foreign substances contained on the surfaces of the minerals.

The drying furnace is composed of a drying furnace in the form of a thermal kiln, and may be dried by adding minerals, but the mineral is put into a conveyor moving through the kiln and moved by heating for about 10 to 20 minutes while heating by applying heat of about 750 ° C. or higher to dry it. The method of forming is preferable because mass production is possible.

Of course, in some cases, it is possible to inject minerals into a rotary furnace that is mounted to be inclined and heated, so that the drying is not limited to the drying method of the minerals.

Subsequently, the dried mineral was ground finely, and sieved through a sieve having a particle size of 1,000 mesh or more to be processed into fine powder.

The mill is rotated while the cutters face each other, and when the particles are gradually reduced, the mill is processed into a fine powder using a conventional mill that grinds and grinds to collect the powder by dust collection using a filter.

Subsequently, finely ground mineral powder was precipitated in clean water and stirred evenly. The heavy silica sand and chromite subsided and the lighter mica was placed on the top layer.

The water was then discarded and the mica located on the top layer was extracted.

next. The extracted mica was dried and evenly mixed with silver nano powder having a concentration of 10 to 100 ppm and a size of 1 to 10 nm.

At this time, these compounding ratios were mixed evenly so that mica powder 88-92 weight% and silver nano powder 8-12 weight%.

The silver nanopowder used in the present invention was added 0.85 g of silver nitrate (AgNO ₃ ) in the form of a silver compound in an aqueous solution, 30 ml of isopropanol, 5 g of polyvinylpyrolidone, and acrylonitrile as a monomer. 85 g of acrylonitrile) was purged with nitrogen and irradiated with radiation to prepare silver nanopowder having a concentration of 10 to 100 ppm and a size of 1 to 10 nm.

Of course, since the method for producing the silver nanopowder is a known method, a detailed description thereof has been omitted, and the present invention is limited to the method for preparing the silver nanopowder because it can be prepared using other electrical decomposition methods or chemical reduction methods. It doesn't happen.

Silver component has been found to have antimicrobial and bactericidal properties since ancient times, and it is capable of inhibiting the reproduction of mites, harmful bacteria and molds while sterilizing by the strong bactericidal and antimicrobial properties of silver nanos. Not only can the cleaners be used more cleanly, but even if the beddings are infected with bacteria, they can be used in a very hygienic way because the bacteria are sterilized by 99% or more within one hour by the sterilizing power of silver nano. There is an advantage such as to increase the external competitiveness as possible.

Subsequently, the evenly mixed powder is mixed at a ratio of 3 to 7% by weight based on the polyester powder for fiber production, the evenly mixed raw materials are introduced into an extruder, heated to a temperature of 180 to 240 ° C, melted, and extruded with a screw. The monofilament was prepared by spinning with a spinneret having a size of 1.5 to 2 deniers.

Subsequently, the monofilament was stretched and spun together to prepare a multifilament-like cotton.
