[0005]

BEST MODE FOR CARRYING OUT THE INVENTION The polylysine in the present invention will be described. Polylysine is, for example, JP-A-59-2035.
The ε-L-polylysine-producing strain Streptomyces albus subspecies lysinopolymeris, which is a polylysine-producing bacterium belonging to the Streptomyces family described in JP-A-9-, is cultured in a medium, and ε-is obtained from the obtained culture. L
-It is obtained by separating and collecting polylysine.
Lysine is an amino acid having two amino groups in one molecule, and polylysine composed of this is generally α-polylysine in which an amino group at the α-position is condensed with a carboxyl group, and an amino group at the ε-position is condensed with a carboxyl group. There are two types of ε-polylysine mentioned above, but ε-polylysine is preferable from the viewpoint of safety. Furthermore, ε-polylysine is a substance listed in the list of food additives other than chemical synthesis compiled by the Ministry of Health and Welfare, and since it is used as a food preservative, it is an antibacterial agent for food containers and packaging materials. Suitable for imparting sex. Although polylysine can be used in a free form, it can also be used in the form of a salt of an inorganic acid such as hydrochloric acid, sulfuric acid, phosphoric acid or an organic acid such as acetic acid, propionic acid, fumaric acid, malic acid, citric acid. There is essentially no difference in the antibacterial effect of ε-polylysine, whether in the free form or in the form of a salt with the above-mentioned inorganic acid or organic acid. The polylysine salt is produced by a conventional method. For example, the polylysine is dissolved in a water-containing methanol solution, and the acid is added thereto. When the solution passed the neutralization point, cold acetone was added to precipitate the salt,
Allow it to dry. When the method of kneading polylysine or its salt into the fiber is adopted, this is crushed with a ball mill or the like before use.

As the fiber material used for the antibacterial fiber of the present invention, a thermoplastic resin having no affinity with polylysine or its salt is used. For example, polyolefin resins such as polypropylene and polyethylene, particularly high density or highly crystalline polyolefin resins are preferable. As a method for producing an antibacterial fiber containing polylysine or a salt thereof inside the fiber, a method of kneading polylysine or a salt thereof into the fiber is preferable, and 0.01 to 5 relative to the entire fiber mass.
% Mass%, preferably 0.1 to 3 mass% of polylysine or a salt thereof is mixed and added to the polyolefin resin. When the content of polylysine is less than 0.01% by mass, a sufficient antibacterial effect cannot be obtained, and even when it exceeds 5% by mass, the antibacterial property has almost reached a saturation state. It is not preferable because it causes The antibacterial fiber obtained by the kneading method has excellent washability and has a long lasting antibacterial effect.

Organic fibers having a fiber diameter of 2 decitex or less are
It is a fiber that is effective for increasing the degree of entanglement when three-dimensionally entangled by a high-pressure water stream, and a fiber selected from plant fibers, animal fibers, regenerated fibers, semi-synthetic fibers, and synthetic fibers is used alone or in a mixture. It

The vegetable fibers include cotton and hemp (flax, ramie), and the animal fibers include silk and wool fibers.

Regenerated fibers are rayon and cupra, semi-synthetic fibers are acetate, triacetate and promix, and synthetic fibers are nylon, acrylic, vinylon, vinylidene, polyvinyl chloride, polyester, polyethylene and polypropylene. Fibers such as, benzoate, polycral, and phenolic are listed.

The definition of the fibers described in the above paragraphs 0008 to 0009 is based on the Fiber Handbook (1993 edition).

In addition to the above fibers, the organic fibers having a fiber diameter of 2 decitex or less include plant fibers such as wood pulp such as softwood pulp and hardwood pulp, and woods such as straw pulp, and herbs. . In addition, waste paper,
Pulp fibers obtained from broke paper are also included, but in order to obtain sufficient entanglement with antibacterial fibers and tensile strength, synthetic fibers such as nylon, acrylic, vinylon, polyester, polyethylene, polypropylene have short fiber strength. It is effective because it is expensive. When the fiber diameter of the organic fiber exceeds 2 decitex, good entanglement cannot be obtained, the fiber may fall off, or the tensile strength may not be sufficiently obtained. The length of the fiber is not particularly limited, but when the web is produced by the wet papermaking method, it is 2
A range of up to 20 mm is preferred.

The water-absorbent fiber means that the completely dried fiber is soaked in water for 5 minutes and then taken out for 1 minute, and its mass is 1.1 times the mass of the fiber before soaking (in this case, the water absorption ratio). 1.1) or more, the fibers are rich in the liquid-absorbing ability of the gravy produced from raw meat where fish is easily proliferated and the fish juice produced from fish, and the polylysine which is an antibacterial agent. It is for absorbing and retaining the water necessary for effectively drawing out antibacterial properties, and for example, among the above-mentioned organic fibers, wood pulp such as softwood pulp and hardwood pulp, and wood pulp such as straw pulp, bamboo pulp, and kenaf pulp. Examples include botanicals, herbs, plant fiber cotton, hemp (flax, ramie), regenerated fiber rayon, cupra, collagen, alginic acid, chitin, and synthetic fibers containing a water-absorbing polymer. Of these, pulp, rayon, cotton and the like are preferable in consideration of the entanglement, flexibility, and homogeneity of the fibers. The weight of a web containing water-absorbent fibers and three-dimensionally entangled by a high-pressure water flow is not particularly limited, but is 10 to 500 g / m ^2.
Is generally, and preferably 50 to 300 g / m ² .

The three-dimensional entanglement by the high-pressure water flow will be described. After making a web containing antibacterial fibers, organic fibers of 2 decitex or less, and water-absorbent fibers by a wet papermaking method, a carding method, an air laid method, etc., high pressure is applied on a porous support to be conveyed to the web. A stream of water is jetted to entangle the fibers three-dimensionally. The porous support is a wire made of metal such as stainless steel and bronze, or plastic such as reinforced polyester and polyamide in a weave such as plain weave and twill weave, preferably about 10 to 250 mesh. The high-pressure water stream is a water pressure of 5 × 10 ⁵ to 2 × 10 ⁷ Pa and is a jet of water having a diameter of 50 to 300 μm ejected onto the surface of the web from nozzles arranged in a single row or multiple rows. The shape of is preferable. The interval between the pores is preferably about 0.2 to 3 mm, more preferably 0.4.
~ 2 mm. The number of nozzles for injecting a high-pressure water stream is not particularly limited, and if it is desired to inject a large number of times, two or more rows can be installed on the porous support. The web obtained by three-dimensionally entangled with a high-pressure water stream can obtain strength without adding binder fibers such as heat-fusible fibers or binders such as latex, starch, and cationic polyacrylamide. Not only does it basically not contain the substance described above, but since the fiber surface is washed with a stream of water, oil agents and fine fiber scraps on the fiber surface are also removed. It is suitable for use as a member that comes into direct contact with the skin. At the same time, the feel (feel) of the web is soft, which makes it suitable for a care sheet.

The adsorbent used in the present invention removes a bad odor which cannot be solved by the antibacterial effect of polylysine.
For example, clay-based, zeolite-based, acid clay-based, activated clay-based, bentonite-based, activated carbon-based, inorganic compound-based, and polymer compounds having an acidic group or a basic group can be used. Preferred is a zinc aluminosilicate system which is effective in adsorbing ammonia, trimethylamine, hydrogen sulfide, ethyl mercaptan and the like. Specific examples include Mizukanite AP, Mizukanite AG, Mizukanite HP, Mizukanite HG, and Mizukanite MP manufactured by Mizusawa Chemical Industry Co., Ltd. The content of the adsorbent in the sheet of the present invention is 1 square meter (1 m
² ) 3 to 500 g is suitable amount, preferably 10
~ 300g. If it is less than 3 g, sufficient deodorizing property cannot be obtained. On the other hand, when the amount exceeds 500 g, the deodorizing property is sufficient and satisfactory, but it is excessive, and it is difficult to hold the deodorizing property on the sheet and the weight becomes heavy, which makes it difficult to handle.

The nursing care sheet of the present invention may be used alone or in a state of being sandwiched between a liquid permeable member and a liquid impermeable member and laminated. In particular, it is effective to make the surface of the liquid permeable member a hydrophobic fiber or the like so as to reduce the water content on the contact surface with the patient as much as possible and prevent discomfort. In the case of animals as well, hydrophobicity has the effect of preventing urine or the like from adhering to the surface of the foot or body and contaminating the surroundings.

In the care sheet, by adhering the polylysine-containing sheets to each other, the adsorbent may be used together with the binder particles such as polyethylene or polyvinyl acetate between the sheets by heat compression treatment, or the polylysine-containing sheet may be included. It is possible to use a material in which an adsorbent and binder particles are enclosed between a sheet and another non-woven fabric.

The cloth will be described. The cloth described in the present invention is capable of imparting strong tensile strength and tear strength, which are difficult to achieve with a sheet alone, and refers to a woven fabric, a knitted fabric, and the like, and the weaving method and the knitting method are not particularly limited. As the woven fabric, a plain weave, a twill weave, a satin weave, or another woven fabric, and as the knitting, a flat knit, a rubber knit, a pearl knit, a double-sided knit, a single tricot knit, a single cord knit, a half tricot knit, Plain tricot knitting,
Warp knitted fabric such as queens cord knitting can be used.
As these cloths, fibers such as nylon, acrylic, vinylon, vinylidene, polyvinyl chloride, polyester, polyethylene, polypropylene, benzoate, polyclar, and phenol fibers can be used alone or in appropriate combination depending on the application. When three-dimensionally entangled with a high-pressure water stream, by sandwiching a strong cloth between the web and the porous support, the fibers in the web are three-dimensionally entangled with the cloth, so that both are firmly bonded together. Therefore, it becomes possible to make a web having both the water absorbency of the web and the strength of the cloth, and it becomes possible to make a sheet which can endure the tension due to friction and movement in the applications such as a care sheet.

[0031]

[Table 1]

The sheets of Examples 1 to 8 contained antibacterial fibers and polyester fibers, and had good tactile sensation and excellent antibacterial properties. Compared to Example 1, Example 2 contained rayon fiber as the water-absorbent fiber, and therefore was excellent in both antibacterial property and deodorant property, even though the polylysine content was the same. The sheet of Example 6 was used as a sheet for laying on a bed for nursing care for one day and then washed, but there was no tear or fray. Further, since the water-absorbent fiber was rayon, the touch feeling was very excellent. The sheet of Example 7 was particularly excellent in deodorizing property because it was sandwiched with a zinc aluminosilicate-based adsorbent. The sheet of Example 8 was particularly excellent in deodorizing property because it was sandwiched with a zinc aluminosilicate-based adsorbent as in Example 7. Furthermore, since a hydrophobic polypropylene non-woven fabric is used on the surface, the surface of the sheet after the deodorization test was not wet. Further, since the liquid impermeable polyethylene film was laminated on the back surface, no test liquid (human urine) leaked even when the back surface was touched. Since the sheet of Comparative Example 1 does not have polylysine added thereto, it has no antibacterial property and is poor in deodorizing property. In Comparative Example 2, the antibacterial fiber is used, but the sheet is not entangled with water, so that the sheet has a solid feel and is not suitable for a care sheet. In addition, since the adhesion of fibers to each other was insufficient and the fibers were often dropped off, it is possible to absorb the juice and the like generated from foods, etc., but the fibers adhere to foods, etc., so it cannot be used. Absent.
