る。Thus the fabric is formed by is it essential basis weight is 20~300gr / m 2. Cloths having a basis weight of less than 20 gr / m 2 are difficult to handle in packaging and lack gas barrier properties and bacteriostatic properties as described below, and the present invention cannot be achieved. If the basis weight is more than 300 gr / m 2 , it is not preferable because not only the formation of the fabric and the handling of the package become difficult, but also the finish of the package and the advantage of the cost of the packaging material are lost. Including the advantages of handling and cost, as a more preferred embodiment is a basis weight of 30 to 200 gr /
m 2 is recommended. It should be noted that there is no problem in mixing acrylic fibers with fibers other than acrylic fibers, for example, fibers that can serve as a binder, such as heat-fusible fibers, or fibers that are added for the purpose of increasing the amount, in accordance with the usual method of fabric formation. Examples of these fibers include polyethylene, polypropylene, nylon, esters, polyvinyl alcohol, rayon,
Examples include synthetic fibers such as cotton and hemp, semi-synthetic fibers, and natural fibers.

で行なえるので有利である。The fabric of the present invention is used as it is for a packaging material for dairy products, etc., and a laminate of the fabric and a film is more preferably used for the packaging material. Commercially available films are advantageously used for such laminates, and polyethylene, polypropylene, nylon, ester, polyvinyl chloride, polyvinylidene chloride, polyvinyl alcohol and the like are recommended as materials. A conventional method can be used for the lamination method. For example, a hot roll method, a hot pin method, or the like is suitably employed. In the case of a laminate with such a film, it is preferable to provide fine holes in the film, and the hot pin method is advantageous because lamination and formation of the holes can be performed in one step.

させ、周辺への臭気の拡散も防いで衛生的である。The packaging material made of a laminate with the film is used such that the surface of the film where the cloth is not present is in contact with food such as dairy products at the time of packaging, and can be opened without sticking fibers to the food. It is easy and the exudate from the built-in food flows out through the fine holes of the film that have been in contact with the food, and this is absorbed and retained by the cloth layer located on the upper layer of the film. Drying is prevented. The above description is an example of laminating a film on one side of a cloth, but does not exclude laminating a film on both sides of the cloth. In such a product in which a film is laminated on both sides, it is preferable that the fine holes provided in the film exist only on one side depending on the purpose of use. The film on the non-contact side with the food is sanitary because the nonwoven fabric of the intermediate layer absorbs and holds the exuding component from the food, which is adsorbed and held, and prevents the diffusion of odor to the periphery.

ロン等が例示できる。Further, the present invention also includes a packaging material composed of an acrylic fiber cloth having a basis weight of 20 to 300 gr / m 2 and a super absorbent fiber cloth. Here, the super-absorbent fiber is a fiber having a high water-absorbing property, and its water-absorbing capacity is 2 to 300 (indicating how many times the weight of the absorbed water when the water absorption equilibrium is reached). The doubled fiber, for example, commercially available products include Lanseal manufactured by Nippon Xlan Industrial Co., Ltd. and super-absorbent cashmere manufactured by Asahi Kasei Kogyo Co., Ltd.

である。Such a super-absorbent fiber cloth can be formed into a cloth similarly to the acrylic fiber cloth of the present invention by employing the above-mentioned ordinary method. A packaging material composed of an acrylic fiber cloth and a super-absorbent fiber cloth may be fixed by laminating the two cloths together, or sandwiching or embedding the other cloth with one cloth. And the super-absorbent fibers are mixed (blended), and the cloth is formed at a stroke to form a packaging material. The mixing ratio of the superabsorbent fibers to the acrylic fibers when mixed (blended) is not generally defined because it depends on the water absorption ratio of the superabsorbent fibers, but is generally 1 to 50% by weight (based on the acrylic fibers).

て使用される包材はこの効果がさらに高められる。(Operation) The reason why the packaging material for dairy products and the like used in the present invention exhibits excellent various performances in this field has not been sufficiently elucidated, but is generally considered as follows. In other words, the acrylic fiber material is probably derived from the electronic properties of its nitrile group, but has a bacteriostatic action that suppresses the invasion and growth of molds (fungi) and bacteria, and thus originates from these causes. Protect the contents of the package from rot. Employing the cloth form contributes to the prevention of the invasion of the microorganisms by the micropores formed by a large number of fibers, and at the same time, the exuded components from the content food are adsorbed and held in these micropores, and the flavor of the food is increased. Prevent drop. In addition, the cloth formed of a large number of fibers, due to the fact that the fibers are arranged irregularly and the total fiber surface area is large, the atmosphere of the outside world mainly to the diffusion of air and the content food, and then to the contact, High resistance may also be the cause of high performance. This effect is further enhanced by the packaging material used in the present invention of a laminate with a film.

異り自由度が低下しており融解が極めて遅いこと、なら
びに凍結層のガスバリア効果が高いことによる。The packaging material used in the present invention, which comprises a super-absorbent fiber cloth, has an effect of actively absorbing and fixing exuding components from the content food, and significantly prevents a decrease in flavor. The storage and transportation of fresh foods are generally carried out in a refrigerator (car). However, if the above-described superabsorbent fiber cloth is used as a packaging material after absorbing water and then freezing, the freshness of the food is extremely good while being refrigerated. This is due to the fact that the bound water in the superabsorbent fiber has a lower degree of freedom than normal free water and has a very low melting degree, and the frozen layer has a high gas barrier effect.

出来るという効果も発揮する。When the above superabsorbent fiber is used after absorbing water in advance, adding alcohol having bactericidal activity, vinegar, or the like to the water suppresses the invasion of bacteria and the like, and further increases the effect. . In addition, the storage temperature is set at 0 to prevent the destruction of cells such as dairy products and / or the quality change.
If the temperature is not lowered to below ℃, the water absorbed by the superabsorbent fiber is solidified at a high temperature, for example, at a temperature of 0 ° C or higher. Can be solidified at 0 ° C. or higher because the packaging material can be solidified at 0 ° C. or higher. Therefore, despite storage at 0 ° C. or higher, cells such as dairy products are destroyed and / or the quality is not changed and bacteria enter and propagate. The effect of suppressing and preserving is also exhibited.
