Abstract

PURPOSE:To prevent a hole from being blocked after having formed and to provide favorable water drainage by fusion-forming a plurality of the holes on a bag made of nonwoven fabric including thermal fusing fibers. CONSTITUTION:This drain bag for garbage, is formed of a plurality of holes 2 for water drainage, fusion-formed on a bag 1 made of nonwoven fabric including thermal fusing fibers. The thermal fusing fibers are constituted by the fibers with the melting point of about 120 to 200 deg.C, and for example, a single fiber such as polypropylene or nylon or a composite fiber such as polyethylene- polypropylene and polyethylene-polyster is used. The thermal fusing fiber included in the nonwoven fabric is more than 40weight% and the plurality of holes 2 are formed on the bag made of this nonwoven fabric by piercing a heated needle in it. The holes are prevented from being blocked after they are formed since a heated needle is used.

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a bag for draining garbage and a method for producing the same, in which a bag made of a non-woven fabric containing heat-fusible fibers is melt-formed with a plurality of holes for draining.

[0002]

2. Description of the Related Art In order to clean domestic wastewater discharged from a kitchen, a sink is provided with triangular corners or strainers to collect garbage.
In this case, it is difficult to clean the triangular corners or strainers, so paper or non-woven bags are put in these and garbage is collected in these bags.

[0003]

Since the conventional garbage collection bag is good for collecting garbage, but the drainage is poor, so that water does not overflow from the triangular corners or the bag in the strainer. It had the drawback of having to drain the water little by little.

The present invention has been made to solve the above-mentioned drawbacks of the conventional garbage collecting bag, and provides a draining bag for collecting garbage having excellent drainage characteristics and a method for producing the same. The purpose is to

[0005]

According to the present invention, a bag made of a non-woven fabric containing heat-fusible fibers is melt-formed with a plurality of holes for draining water, and a drainage bag for collecting garbage, and a heat-melting bag. There is provided a method for producing a water drainage bag for collecting garbage, which comprises passing a heated needle through a nonwoven fabric containing adhesive fibers to melt and form a plurality of holes in the nonwoven fabric.

[0006]

In the drainage bag for collecting garbage according to the present invention, since the holes for draining water are formed by melting, they are not clogged after the holes are formed, and the drainage characteristics can be improved.

[0007]

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS A drainage bag for collecting garbage according to the present invention (hereinafter referred to as a drainage bag) will be described below with reference to the drawings.

FIG. 1 shows an embodiment of the drainage bag of the present invention.
In the figure, 1 is a bag made of a non-woven fabric containing heat-fusible fibers,
Denoted at 2 is a hole for draining water formed in the bag 1 by melting.

The heat-fusible fiber which can be preferably used in the present invention is a fiber having a melting point of about 120 to 200 ° C. Specific examples include single-component fibers such as polypropylene and nylon, composite fibers such as polyethylene-polypropylene and polyethylene-polyester, and composite fibers of polyester with a high melting point and polyester with a low melting point. Fiber etc. are mentioned. Of these, polyethylene-polypropylene composite fibers and polyethylene are preferred in terms of cost and productivity of nonwoven fabrics.
-Polyester composite fibers are preferred.

In the drainage bag of the present invention, it is preferable that the non-woven fabric contains 40% or more of heat-fusible fibers. If the heat-fusible fiber content is less than 40%, the strength of the bag will be insufficient and there is a risk of damage.

The plurality of holes for draining water can be formed, for example, by passing a heated needle through a bag made of the non-woven fabric. If the needle is not heated, even if a hole is formed by penetration, the hole will be closed after that. However, when the needle is heated and penetrated, the non-woven fabric around the needle melts, so the hole is not blocked even after the needle is pulled out, and the size can be kept constant.

The size of the holes is preferably 0.7 to 2.0 mm in diameter. If the diameter of the hole is smaller than 0.7 mm, the water will not drain easily. On the other hand, if it is larger than 2.0 mm, small dust will flow out.

The number of holes is preferably 25 to 400 per 100 cm ² , and the smaller the hole diameter, the smaller the hole diameter, and the smaller the hole diameter, the larger the number of holes.

The heating temperature of the needle is usually preferably 150 to 170 ° C. If the heating temperature is too low, there are problems that the pores become small and that the burrs of the pores on the back surface of the non-woven fabric appear to lose smoothness. Further, if the heating temperature is too high, there is a problem that the size of the holes is likely to change even if the operating speed is slightly increased or decreased.

FIG. 2 is an explanatory view showing a state in which the drainage bag shown in FIG. 1 is actually used as a strainer for the drainage port of the sink. In FIG. 2, 3 is a strainer, and 4 is the garbage collected in the bag.

Next, a method of manufacturing the drainage bag of the present invention will be described with reference to FIG. First, the hot plate 5 to which a large number of needles 6 are attached, and the receiving plate 7 having a hole through which the needles 6 penetrate are arranged facing each other. The receiving plate 7 is fixed, and the heating plate 5 can move up and down. The heating plate 5 is connected to a heat source (not shown),
The temperature can be adjusted in the range of about 150 to 190 ° C.
Position the non-woven fabric 8 between the heating plate 5 and the receiving plate 7,
The hot plate 5 is lowered toward the receiving plate 7 to melt-form the draining holes in the nonwoven fabric 8. Then, the hot plate 5 is raised and the nonwoven fabric 8 is moved. By repeating such steps, the nonwoven fabric for draining bags of the present invention is manufactured. After that, bag making is performed according to a usual method. In addition, you may perform melt formation of the hole for draining, after bag making.

EXAMPLE 18 g / m prepared by passing a mixed web consisting of 70% by weight of polyethylene-polypropylene composite fiber as a heat-fusible fiber and 30% by weight of polyester fiber through a hot roll.
A draining bag having a width of 235 mm and a depth of 240 mm was prepared using the non-woven fabric of ² . After that, using a hot needle heated to about 160 ℃,
Draining holes having a diameter of 1.5 mm were melt-formed at a density of 250 per 100 cm ^{2 in} this draining bag.

Using this drainage bag and, as a comparative example, a bag made of the same material in which holes for draining water were not formed, an evaluation test of drainage property was conducted under the following conditions.

Test conditions 20 g of rice bran, 2 g of vegetable oil, 0.2 g of detergent and 5 g of wheat flour dispersed in 4 liters of water are poured into the drainage port of the sink at once, and the time until the water is drained is measured (1
Second time). Repeat the same measurement after the water is completely drained from the bag.

The test results are shown in Table 1.

[0021]

[Table 1]

It can be seen from Table 1 that the water draining bag of the present invention has extremely excellent drainage characteristics as compared with the conventional water draining bag.

[0023]

EFFECTS OF THE INVENTION The present invention provides a drainage bag for collecting garbage having good drainage characteristics and a method for producing the same.
