Hereinafter, the first embodiment of the present invention will be described with reference to FIGS.

Best mode 1.

As shown in Fig. 1, copper chlorophyllin Na (B), which has a chemical structure that is robust to sunlight, according to Best Mode 1 is composed of magnesium (the center of chlorophyll molecule) in chlorophyll contained in fresh leaves (green leaves) of Kumazaza. Is replaced with copper, and the phytol group is hydrolyzed with an alkali to form a water-soluble Na salt, ie, subjected to copper chlorophyllination (step S1), followed by centrifugation ( It is obtained by performing step S 2).

That is, the residue (1) (= leaf residue) extracted by the centrifugation contains copper chlorophyllin Na (B) having a chemical structure that is robust to sunlight as shown in FIG.

The supernatant separated by the above centrifugation (Step S2) can be neutralized and used as a drug such as a gastrointestinal drug. This drug contains copper chlorophyllin Na (A) having a chemical structure as shown in FIG.

It is to be noted that the ^Γ kumazasa "and is a kind of bamboo Poales Poaceae, are those green leaves is named since the white" Sasa "in the fall, since ancient times, bamboo dumpling, Sasaame, Zongzi It has also been used for medical purposes, and is also called "zumikosa".

The above residue (1) has excellent antibacterial properties without green color fading over a long period of time. The reason for this is that during the processing in steps S1, S2 above, It contains about 0.1% of copper chlorophyllin Na (B), which has a robust structure. As shown in FIG. 3, this copper chlorophyllin Na (B) has a maximum absorption wavelength at 627 nm and is robust to sunlight. That is, the antibacterial substance contained in the copper chlorophyllin Na (B) hardly decomposes even after exposure for 20 hours.

Therefore, the above-mentioned residue (1) can be used, for example, in detergents, stones, shampoos, cosmetics, dentifrices, socks, bottles, pillowcases, blankets, evening baths, bath towels, ri-ten, wallpapers, sabo nights , Bandages, gauze, plasters, underwear, bras, hats, parasols, jackets, shirts, and other textile products, knitted products, pool / bath purifiers, cold storage cabinets and other deodorants, sealing agents, By using it when making a practical product such as a toilet water purifying agent, it is possible to obtain the above-mentioned various practical products that can maintain antibacterial properties for a long period of time even when used for a long period of time.

Best mode 2.

Since the above residue (1) contains only about 0.1% of copper chlorophyllin Na (B), as shown in FIG. 4, the above residue (1) is further weakened as shown in step S3. The residue (2) containing about 50% of the above-mentioned copper chlorophyllin Na (B) can be obtained by performing the treatment with an alkaline (step S3).

Therefore, by using the above-mentioned residue (2) when producing the above-mentioned various practical products, the antibacterial property can be maintained for a long period even in daily long-term use, more than the practical product obtained in the best mode 1. Various practical products can be obtained.

Best mode 3.

Since the above-mentioned residues (1) and (2) are difficult to use for the production of the above-mentioned practical products as they are, as shown in FIG. 5, after the above-mentioned residues (1) are treated with an alkali (step S3), the residue is removed. A squeezing treatment (Step S4) separates the residue pulp (3) containing copper chlorophyllin Na (B) and the aqueous residue extraction pigment solution (4) containing copper chlorophyllin Na (B). Since the residue pulp (3) and the residue extraction dye aqueous solution (4) have been subjected to the weak alkali treatment in step S3, they contain a large amount of the above-mentioned copper chlorophyllin Na (B).

Therefore, by using the above-mentioned residue pulp (3) or aqueous solution of the residue-extracting pigment (4) when making the above-mentioned practical products, antibacterial activity can be maintained even after long-term daily use. Various practical products described above that can maintain the properties for a long period of time can be obtained.

Further, according to Best Mode 3, a residue pulp (3) and a residue extraction dye aqueous solution (4) that are easy to add when producing the above-mentioned practical product and are easy to use for producing the above-mentioned practical product are obtained.

In place of steps SI and S2 in Fig. 1, the magnesium in the chlorophyll contained in the leaves of the plant is replaced with iron, hydrolyzed with alkali, and then separated to separate the residue (= leaf residue). In addition, as in step S3 in Fig. 4, this residue was treated with weak alcohol, and the magnesium in the chlorophyll contained in the leaves of the above plants was replaced with iron and hydrolyzed with alkali. After the separation, the residue (= leaf residue) obtained by separation is subjected to roller squeezing treatment in the same manner as in step S4 above, and the residue pulp and the residue dye aqueous solution are also mixed with the copper chlorophyllin. Like Na (B), it contains iron chlorophyllin Na, which has a chemical structure that is robust to sunlight (the chemical structure in which “Cu” is replaced with “Fe” in the center of FIG. 2). Same as above The use in making the seed utility goods, the same effect as the above best mode are obtained.

Residues (1) and (2) containing copper chlorophyllin Na (B) (or iron chlorophyllin Na having a chemical structure that is robust to sunlight), residue pulp (3), and residue extraction dye aqueous solution (4) The same effects as those of the above-mentioned best modes can be obtained even if the ones produced by the same processing as the above-mentioned best modes from plants other than the leaves of Kumazaza are used when making the above-mentioned various practical products. .

Best mode 4.

The following describes a paper thread that is capable of producing a woven fabric or knitted fabric that is excellent in antibacterial properties and the like as a practical product containing copper chlorophyllin Na (B) and the like, and a method of manufacturing the same. There is known a paper thread in which a paper tape having a width of about 1 Omm is twisted and used as a thread. For example, Japanese Patent No. 2994209 discloses a paper thread formed by twisting a water-resistant paper tape using a combination of a wet paper strength enhancer and a dry paper strength enhancer to form a string. However, these paper yarns cannot be used to produce woven or knitted fabrics that have good antibacterial properties and are healthy. The paper thread according to Best Mode 4 is a copper chlorophyllin Na (B) having a chemical structure that is robust to sunlight by adsorbing the above-mentioned aqueous solution of the extracted pigment on paper pulp, adding a water-resistant agent, and then making the paper. Alternatively, a paper containing iron chlorophyllin Na is prepared, or paper pulp and the above-mentioned residue pulp are dispersed in water, and a water-proofing agent is added thereto, and then the paper is made and the copper chlorophyllin Na ( B) Or paper containing iron chlorophyllin Na was prepared, and this paper was cut and twisted with a paper tape.

Specifically, for example, a paper containing the above-mentioned copper chlorophyllin Na (B) is prepared by adsorbing the above-mentioned aqueous extract solution (4) on the paper mulberry pulp, which is a raw material of Japanese paper, adding a water-resistant agent, and then making the paper. Alternatively, the above-mentioned residual pulp (3) and the above-mentioned mulberry pulp are dispersed in water, and a water-proofing agent is added thereto, and then the paper is made to make the above-mentioned paper containing copper chlorophyllin Na (B). The paper yarn is manufactured by twisting the cut paper tape.

In this case, in the case of the extracted pigment aqueous solution (4), the amount is preferably 1 to 3% of the mulberry pulp, and in the case of the residual pulp (3), the mixing ratio is preferably 1 to 2%. Also, the above paper tape is, for example, 2mn! It is cut to a width of about 1 Omm. This cutting is performed, for example, by a dedicated cutting device in a process before a feed roller described later.

The paper tape 1 is twisted while the steam from the heat box 3 is uniformly applied to the paper tape 1 to produce a paper thread 10.

The feed port 2 is composed of one long rotating roller 2A that is rotated by the drive shaft 2a, and a plurality of weight ports 2B that are allocated to each paper tape and connected by the connecting shaft 2b. , 2B ... The rotating roller 2A is composed of a metal roller, The weight roller 2B is formed by attaching a tube 2c of rubber or the like to the outer periphery of a metal roller so that the paper tape 1 is hard to cut.

The heater box 3 is provided on the rear side of the rotating roller 2A, and is an elongated rectangular box that is installed slightly below the position of the rotating roller 2A along the axial direction of the rotating roller 2A. It is.

A heat insulating material 4 such as a foamed foam mouth is attached to the inner wall of the heater box 3. In addition, a heat pipe 5 is arranged inside to heat the contained pure water 6 to generate steam 6H.

In addition, twisting stops 3b, 3b,... Are provided on the upper edge 3a of the heater box 3 far from the feed roller 2 corresponding to the position of each weight roller 2B. The twist stop 3b may be formed by a rounded corner formed on the upper edge 3a of the box 3 or made of stainless steel on the upper edge 3a of the box 3 above. Alternatively, a rounded member may be provided. Further, the upper edge 3a of the heater box 3 itself (that is, the corner of the upper edge 3a) may be used as a twist stop.

A steam outlet 3d is formed on the upper surface 3c of the box 3 corresponding to the position of each twist stop 3b, and the steam from each steam outlet 3d is supplied to each weight. It hits each paper tape 1 guided from the position of the roller 2B to each twist stop 3b.

The number of twists of the paper thread 10 is usually determined by the rotation speed of the rotating roller 2A and the rotation speed of the spindle 7.

In FIG. 6, reference numeral 9 denotes a disk attached to the wooden tube 8, 9a is attached to the outer periphery of the disk 9, and guides the twisted paper thread 10 to the wooden tube 8. Traveler 11 denotes an intermediate guide. Reference numeral 12 denotes a drive belt for rotating the spindle 7. 10A indicates a state in which the paper tape 1 is twisted after being twisted and passed through 3b.

Therefore, after the steam hits each paper tape 1 sent by the feed roller 2, each paper tape 1 is guided to each twist stop 3b, and immediately after passing through the twist stop 3b, the steam is supplied and becomes soft. The resulting paper tape 1 is twisted by the rotation of the spindle 7 and wound as a paper thread 10 on a wooden tube 8 rotated by the spindle 7.

The copper chlorophyllin Na (B) or iron chlorophyllin Na can maintain antibacterial properties for a long time, and has high practicality, good health, and soft fabrics and knitted fabrics. can get.

The fibers used for paper are different from the fibers for clothing such as cotton and hemp, and the fibers are short. (The raw material for paper is 2 mm or less in length, and the raw material for Japanese paper is 6 mm or more in fiber length. However, as mentioned above, paper is made by adding a waterproofing agent to paper pulp dispersed in water and then making paper.In particular, when manufacturing Japanese paper, it is necessary to disperse it in water to form a two-dimensional sheet. In addition, a process called suki is performed to increase the entanglement of the fibers. In addition, paper is produced by dispersing in water water with a porous structure consisting only of cell membranes, which has been pulped (boiled with alkali) and the resin content in the fibers has been washed away. Therefore, the paper thread 10 formed by twisting the paper tape 1 obtained by cutting the paper manufactured as described above as described above has a structure in which the fiber itself has many voids.

Therefore, the paper thread 10 has an effect such as antibacterial property by the above-mentioned copper chlorophyllin Na (B), has excellent heat insulating properties, is excellent in moisture absorption / exhaustability, has little stickiness, and has an ultraviolet blocking effect. Have.
