Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a kitchen draining bag and a method for manufacturing the same.

[0002]

2. Description of the Related Art In daily life, garbage generated in the kitchen at any time, such as food scraps, fish bones, vegetable scraps, cooking scraps, food packaging materials, coffee, green tea leaves, tea leaves, fruit chips, etc., is discarded. BACKGROUND ART A kitchen drainer bag is used to collect foods, leftover foods, oil dregs, etc., to separate and remove water to some extent, and then to discard the remaining solids as raw garbage. This kitchen drainer bag is required to have drainage properties in order to filter only water to leave solid matters, and required strength to hold the weight of solid matters.

Conventionally, this kitchen draining bag has a bag-shaped non-woven fabric, woven cloth or net formed of synthetic resin such as polypropylene, polyethylene, polyester, nylon, polyurethane, or a synthetic resin having drain holes. Film bags and the like are commonly used.

[0004]

However, in the conventional kitchen drainer bag, the amount of oil adsorbed is small because the basis weight of the non-woven fabric cannot be increased so much because of the necessity of keeping the drainage property moderate. Leaks out of the kitchen drainer bag together with water and adheres as oil stains to the kitchen sink and drainage port, causing problems in terms of hygiene and maintaining aesthetics.In extreme cases, oil may accumulate inside the drainage port. There was a problem such as clogging the drainage port.

An object of the present invention is to maintain an appropriate drainage property and improve oil absorption without increasing the basis weight.
It is an object of the present invention to provide a kitchen drainer bag that can maintain kitchen hygiene and aesthetics, and can prevent environmental pollution due to clogging of drainage ports and outflow of oil, and a manufacturing method thereof.

[0006]

The kitchen draining bag of the present invention comprises:
It is characterized in that it is made of a spunbonded nonwoven fabric having at least one surface raised. According to the kitchen drainer bag of the present invention,
The raised hair greatly improves the oil absorption, but the drainage tends to be slightly reduced. In order not to impair drainage, one or a plurality of drainage holes having any shape such as a circular shape, an elliptical shape, a rectangular shape, or a part or the whole surface of the bag, preferably a drainage hole having a diameter of 0.2 to 6 mm is used. Opening rate 10 ~ 50%
It is desirable to perforate the entire surface of the bag at a density of, or to perform hydrophilic treatment, for example, with a gravure roll coater.

The spunbond nonwoven fabric used in the kitchen drainer bag of the present invention is preferably made of polypropylene resin, which is preferably a polymer containing propylene as a main component, that is, a propylene homopolymer. Or a copolymer of propylene and another compound copolymerizable with the propylene. Other compounds copolymerizable with propylene include, for example, α such as ethylene, 1-butene, 1-pentene and 1-octene.
-Olefin, vinyl chloride, vinyl acetate, methacrylic acid esters, acrylic acid esters, etc. may be mentioned, and these may be used alone or in combination of two or more in the polypropylene resin. Specific examples of the polypropylene-based resin include propylene / ethylene copolymer, propylene, 1-butene copolymer and the like.

The spunbonded nonwoven fabric used in the kitchen drainer bag of the present invention has a basis weight of 3 to 80 g / m ² , preferably about 5 to 15 g / m ² , and a thickness of 0.1 to ²⁰ m.
m, preferably 0.1 to 0.8 mm, fiber diameter 5 to 5
It is 0 μm, preferably about 10 to 30 μm. The air permeability of, 100~400mml / cm ² · sec, preferably 200~300mml / cm ² · about sec.

In FIG. 1, a spunbonded nonwoven fabric 1 having a raised inner surface is superposed, and a bag 5 in which three sides of a bottom edge 2 and both side edges 3 and 4 are heat-sealed is provided with drainage holes 6 innumerably on the entire front and back surfaces of the bag. The example which formed is shown. The manufacturing method of the kitchen drainer bag described above,
At least one side of the spunbonded nonwoven fabric is raised by a raising means such as a porcupine roll and then cut, and the side edges are heat-sealed to form a bag.

In the present method, the heat fusion can be carried out, for example, by fusing and sealing with a heat cutter, pressure bonding with a high frequency welder, or the like.

[0011]

[Example] Spunbonded nonwoven fabric (trade name: Syntex) PS-105 (fiber diameter: 2) manufactured by Mitsui Petrochemical Industries, Ltd.
Using a denier, basis weight 25 g / m ² , thickness 0.2 mm), one side was raised by a raising device composed of a porcupine roll 11 as shown in FIG.

The porcupine roll 11 has a roll diameter of 8
Using a brass needle 12 having a length of 5 cm and a length of 5 mm embedded at a needle density of 50 needles / cm ² , the non-woven fabric 13 is fed at a speed of 10 m / min, and the porcupine roll 11 is rotated at a peripheral speed of 100 m / min. It was rotated in the same direction as the No. 13 feed. The thickness of the nonwoven fabric after raising was 3 mm. The oil absorption performances of the one-sided brushed non-woven fabric manufactured as described above and the same non-raised non-woven fabric were tested in accordance with the adsorption amount test item in the performance test of the discharged oil control material of the Bureau of Ships of the Ministry of Transport.

That is, a 10 cm square sample was obtained from each of the above nonwoven fabrics, and the weight W ₀ of each sample was measured. Then, each sample was soaked in salad oil made by Nisshin Co., Ltd. for 5 minutes, lifted up, then left horizontally on a wire mesh of 1 cm mesh with the fluff facing downward, and left for 5 minutes, then each weight W ₁ was measured. As a result, as shown in Table 1, the oil absorption amount (W ₁ -W ₀ ) of the napped sample was about 5 g, and it was found that the sample had nearly twice the performance of the non-napped sample.

[0014]

[Table 1]

Next, using a non-woven fabric which has been raised as described above and which has been subjected to hydrophilic treatment by the following method, the inside of the bag has a raised face and is heat-sealed to obtain a folded diameter of 23.5 cm.
A draining bag having a depth of 25 cm was prepared. The hydrophilic treatment was performed by a gravure roll coater as follows. That is, a nonionic polyoxyethylene polyoxypropylene alkyl ether type hydrophilic agent was used in a 3% aqueous solution, and 10 cc /
After coating with a m ² coating roll at a speed of 20 m / min, it was dried in a steam drying oven at 120 ° C.

Drainage was examined by injecting 500 cc of water into each of the bag obtained as described above and the bag obtained in the same manner with a non-raised non-woven fabric. As a result, drainage was completed within a few seconds for both the raised bag and the non-raised bag. Next, a practical performance test was conducted by actually putting food into each of the above bags. That is, when a commercially available retort curry bag was put in each of the above-mentioned bags as a food, water quickly escaped. When the liquid dripping from the bag was dropped into the basin containing water after the water had escaped, the liquid dripping from the bag that did not nap spread widely on the water surface of the basin, but the napped bag It was found that the liquid that dripped more was extremely low in oil, and the oil was sufficiently adsorbed to the bag and retained in the bag.

EFFECTS OF THE INVENTION According to the kitchen drainer bag of the present invention, since it is excellent in oil adsorption, the oil separated from cooking waste and oil dregs does not leak out, and the hygiene and aesthetics of the kitchen are improved. It is maintained, and it is possible to prevent clogging of the discharge port and environmental pollution due to the oil content. In addition, a drainage bag having excellent oil absorption and drainage can be obtained by forming a drainage hole or performing hydrophilic treatment.
