Description

[Detailed explanation of the idea]

0001

[Industrial application field]

This invention is soft, has a good fit, has excellent water drainage, and has excellent dirt removal properties. The present invention relates to a filter bag made of non-woven fabric for draining kitchen sinks.

0002

[Conventional technology]

Traditionally, filter bags for kitchen sink drainers have been made of Japanese paper or cellulose fiber. Manufactured using various staple fibers such as fibers and synthetic fibers alone or in combination. Those made of dry-laid non-woven fabric, those made of wet-laid non-woven fabric, and even those made of high-density polyethylene. By knitting a net type composed of monofilament or nylon filament. Manufactured stocking type ones are typically used.

0003 The ones made of Japanese paper and non-woven fabric mentioned above have excellent ability to capture fine dust, but On the other hand, because the mesh is too fine, it tends to get clogged during use, making it difficult to drain water. There was a drawback. On the other hand, the net type and stocking type mentioned above are eye-catching. The problem is that it drains well due to its rough surface, but its ability to catch fine dirt is poor. was there. In addition, except for stocking types, they generally have a hard texture and are flat bags. Because of this, it has a poor fit to the colander, and in order to improve this fit. If you make a flat bag into a cylinder with gussets on both sides, you can attach it to a colander. A triple overlapping part is formed in approximately half of the bottom, reducing the filtration area and preventing water from draining. There was a problem that it worsened sex.

0004

[Problem that the idea aims to solve]

This invention solves these problems, and is soft, fits well, and drains easily. The purpose is to provide a filter bag for draining kitchen sinks made of non-woven fabric with excellent dirt removal properties. That is.

[0005]

[Means to solve the problem] In order to solve this problem, the present invention uses polyolefin fibers with a single yarn of 3 to 15 deniers. It is made of a non-woven fabric sheet made of fibers, and this non-woven fabric sheet is folded in half. Then, position this folded part at the bottom, form a gusset on the bottom, and It is made by heat sealing.

[0006] The polyolefin fiber used in this invention is 3 to 15 denier, especially 5 to 10 denier. preferred. In general, the size of the space surrounded by fibers where no fibers exist is the size of the nonwoven fabric. It is greatly influenced by the denier size of the single yarns that make up the yarn, and the denier is large. The more the fiber-free space becomes larger, the water permeability increases, and the basis weight in particular increases. The influence of denier is large when it is low.

[0007] When the single yarn is less than 3 denier, the size of the individual spaces where no fibers are present becomes small. , water permeability decreases, resulting in poor drainage. Therefore, the single yarns that make up the nonwoven fabric A larger denier is preferable, but non-woven fabrics that can be manufactured if the single yarn exceeds 15 denier The minimum basis weight of fabric has increased, making it more expensive and making it difficult to obtain a flexible texture. Therefore, a nonwoven fabric made of a single yarn of 5 to 10 deniers is particularly suitable.

[0008] Furthermore, the basis weight of the nonwoven fabric is preferably in the range of 10 to 30 g/m ² . If the basis weight of the nonwoven fabric is less than 10 g/m ² , the amount of fiber groups that make up the nonwoven fabric will be small, which will not only tend to reduce the strength of the nonwoven fabric but also reduce its uniformity, impairing the original function of the filter bag. It will be done. Furthermore, when the basis weight of the nonwoven fabric exceeds 30 g/m ² , not only does the drainage property tend to decrease, but also the cost increases, which is disadvantageous.

[0009] In addition, the polyolefin fiber used in this invention is polypropylene fiber. The core component is polyester polymer or polypropylene polymer, and the sheath component is polyester polymer. Examples include core-sheath type composite fibers made of ethylene polymer.

0010 Next, the present invention will be explained in more detail using the drawings. Figure 1 shows the non-woven fabric base of the present invention. FIG. 2 is a perspective view showing an example of a filter bag for draining a sink, and FIG. 2 is a cross section taken along line X-X in FIG. FIG. In the figure, a non-woven fabric kitchen sink drainer filter bag 1 is used. The polyolefin nonwoven fabric sheet 2 is folded in half at the bottom 3 of the filtration bag 1. A gusset is provided by making a fold 4 in part 3, and both sides 5, 5 are heat-sealed to form a bag. is formed. Therefore, the bottom part 3 of the filter bag 1 made of the nonwoven fabric sheet 2 is No need to seal.

[0011] The nonwoven fabric sheet 2 may be a nonwoven fabric made of short fibers or long fibers. Any of the following nonwoven fabrics can be used.

0012

[Effects of action and invention]

As explained above, the nonwoven fabric kitchen sink drainer filtration bag according to the present invention is made of polyethylene. It is made of a non-woven sheet made of olefin fibers. Water permeability and filter properties based on the lipophilicity of fibers and their single denier This makes it possible to remove not only fine dust but also oil stains dispersed in water. And you can drain the water quickly. In addition, the filtration bag of this invention is highly flexible, The bottom of the bag is folded back to form a gusset, so the joint (heat-sealed part) ), it fits perfectly in the draining container, has excellent draining properties, and is easy to use. It is something.
