Description

The present invention relates to cocoon products such as tatami mats and straws, and a method for producing the same.

Conventionally, a method of dyeing licorice with tea juice has been proposed for cinnamon products such as tatami mats (see Patent Document 1). However, the harvested grass is soaked in muddy water made by mixing clay with water, so-called mud dyeing, sun-dried, stored and stored, then sorted according to length and slightly humidified before weaving. Weaving into the desired product, etc., and then finishing and drying in the sun, but does not sufficiently retain the catechin component. The reason for muddying is that if the cut grass is dried as it is, there is a risk of quality deterioration such as discoloration.

In addition, under the environment where the tea extract was atomized, the licorice was exposed for a predetermined time and dyed. Further, the tea extract was added with an antioxidant.

Also, a weed grass having a sorting process for sorting mud-dyed weed grass, a humidifying process for humidifying the weed grass sorted by this sorting process, and a weaving process for weaving the weed grass humidified by this humidifying process with a loom In the method for producing a product, a method for producing a licorice product for dyeing the licorice by the humidification step using a humidifying liquid used in the humidification step as a tea extract has been proposed. However, sufficient dyeing has not been achieved by the addition of an antioxidant.

In order to provide a cocoon sheet that is effective for a long period of time without damaging the antibacterial and deodorant functions of the green tea component by wiping, etc., after applying green tea extract to the sheet formed using cocoon grass, the resin Is electrostatically painted. It has been proposed that the green tea component-containing green tea extract is coated with a porous coating containing a resin to achieve both protection of the green tea component and functional expression of the camellia sheet (see Patent Document 3). . However, the process is complicated and the price is high.

The present inventor is a product of koji, tatami table, which is obtained by applying a tea extract component and a water-repellent fluororesin to a koji grass used in koji, tatami mat, and heat-treating it. Proposal is made of cocoons and tatami mats that contain a tea catechin component and a fluorine-based resin to provide water repellency and have deodorant, antibacterial and insect repellent effects.

In recent years, the development of antibacterial products has been remarkable, and the number of antibacterial treated products such as synthetic resin products has increased significantly.

There are few antibacterial treatments for tatami mats, which are frequently touched in daily life. The reason for this is that when antibacterial tatami mats are used, treatments that carry antibacterial materials on tatami mats and the like can be easily considered, but tatami mats and urns are large in area and are often in direct contact with the human body. It must be antibacterial material that is harmless to the human body.

Moreover, since the tatami mats and cocoons are traditional products, the conventional touch and texture are important factors, and it is mentioned that these antibacterial treatments cannot satisfy them.

The present invention focuses on the antibacterial and dyeing effects of catechins contained in green tea, and solves the above-mentioned problems by applying them to camellia grass. There is no sense of incongruity in the touch and texture, and the natural material is harmless to the human body. It aims at providing the sanitary licorice product by which antibacterial processing was carried out, and its manufacturing method.

In order to solve the above-mentioned problems, the product can be dyed in a calm color suitable for a tatami mat or a candy, and can be a hygienic licorice product having an antibacterial effect by the antibacterial action of catechin contained in tea.

Incorporating a tea extract and an acid dye into the inside of the grass to make it contain a catechin component and a pigment component, the step of storing the grass bundle in a net bag, and putting the above-mentioned grass bundle into a kettle and washing in hot water It consists of a process, a process in which tea leaves and acid dyes are put into the kettle, a process in which dyes and tea ingredients are immersed and dyed in a bundle of licorice, a process in which it is washed with cold water and dried, and a process in which weaving is performed after wetting. Yes.

In the step of immersion dyeing, a bundle of green grass catechins extracted from tea leaves in warm water and an acidic dye are dissolved in a dyeing kettle, and the bundle of licorice is added and heated to 98 ° C. with steam. And a method for producing a licorice product impregnated with a tea component and a dye component which are immersed while rotating and vibrating for 30 to 120 minutes.

In order to impregnate the tea component and the dye component in the grass, 3 to 10 parts of tea leaves and 0.5 to 7 parts of the dye are added to 1000 parts of hot water with respect to 100 parts of the grass and the solution containing the hot water is added. In contrast, the penetrant is subjected to dip dyeing using 0.01 to 0.5% by weight.

In order to exhibit a lustrous and vibrant color, the catechin component of green tea contains a dyeing agent in which various colors of blue, yellow, black, orange, rubin, and red are added as colored acidic dyes.

Basic dyes are mostly used conventionally. The dyeing technique is simple and the cost of production is low, and recently, the price of goods is decreasing. Furthermore, the basic dye contains malakide green and auramine, which are metallic substances.
