BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a filter cloth.

[0002]

2. Description of the Related Art Conventionally, it is common to use a fibrous structure as a filter material for filtering and purifying a liquid containing foreign matter, but it is immersed in an unclean liquid or dust is attached. As a result, bacteria adhered to and propagated on the filter cloth, and a bad odor was generated by the bacteria. Therefore, it is desired to prevent the bacteria from adhering to the filter cloth and proliferating and generating an offensive odor by using an antibacterial fiber structure as the filter.

As the antibacterial fiber structure, for example, an antibacterial agent obtained by fixing and stabilizing a metal ion having a bactericidal activity to a zeolite substance having a specific physical property is held in the fiber structure. However, when used alone as a filter material, the filterability and strength are not sufficient, and it is difficult for a cloth product to be processed into a predetermined shape as a single unit.

[0004]

SUMMARY OF THE INVENTION The present invention has been made in view of the above-mentioned problems of the prior art, and its purpose is to have a proper filtration ability and strength, and It is an object of the present invention to provide a filter cloth that is not only easy to process into a predetermined shape, but can also prevent bacterial propagation and development of malodor.

[0005]

Means for Solving the Problems Synthetic fiber having antibacterial property
A plain yarn of a round yarn and a flat yarn, and
A web having antibacterial properties was overlaid on a band-shaped hard cloth arranged parallel to the hand direction to form an integral stitch.

[0006]

The hard cloth gives strength to the filter cloth as a reinforcing material and removes relatively coarse dross as a filter material. And if bending a belt-like filter cloth in the widthwise direction, and plain weave
The flat yarn can be easily bent along the texture and can maintain its bent shape, and can be easily fixed to the filter as a single unit.

Since the web is integrally stitched with a hard cloth, the fibers do not come off, and the entangled fiber structure exerts a filtering action. Since both the hard cloth and the web have antibacterial properties, bacterial growth on the filter cloth is prevented, and the liquid to be filtered is sterilized and purified.

[0008]

DESCRIPTION OF THE PREFERRED EMBODIMENTS An example of the implementation of the present invention will be described below with reference to the drawings.

As shown in FIGS. 1 to 3, the filter cloth of the present invention comprises:
The web 2 is cut into a lap belt shape on the hard cloth 1, and the two are integrally formed by sewing the sewing machine stitch 3 and the overedging 4 in the length direction.

Is the hard cloth 1 a synthetic fiber having antibacterial properties?
Formed by plain weaving round yarn 5 and flat yarn 6
Done, And the flat yarns 6 are arranged parallel to the longitudinal direction.
It As the fiber material, for example, a metal ion having a sterilizing power is used.
Stable by fixing zeolite to zeolite material with specific physical properties
Porphyrin mixed with solidified inorganic antibacterial agent and inorganic metal copper powder
Use polyethylene fiber. Polyethylene fiber has resistance to running water
Since there is little, the drainage is good, the bending strength is large, and
Since it has a shape, it is suitable as a reinforcing material. Web 2 and
For example, a polyester containing the inorganic antibacterial agent
Use the one made from cotton.

Next, the operation will be described based on an example of the embodiment.

[0012] filter cloth made of two layers as described above, it is Ru can <br/> hardness th fabric 1 is to fold because they act processed as a reinforcing material. In particular, the flat yarn 6 is made into a round yarn 5 by plain weaving.
Pre-bent slightly along the width so that
Easily bent to form a regular fold, and a bent shape
The state is maintained. Thus, for example, by folding the band-shaped filter cloth alternately in the width direction to form a bellows shape, when the filter cloth is attached to a filter, etc., the filtering area can be increased and appropriate strength can be obtained, so that a supporting member such as a slit can be obtained. It can be easily fixed independently without the provision of. Further, the web 2 exhibits a filtering function as a filter cloth due to the fiber structure in which polyester cotton is entangled, and at the same time, since the web 2 is integrally stitched with the hard cloth 1, the fibers are prevented from coming off. Since the hard cloth 1 and the web 2 both have antibacterial properties, they prevent bacteria from adhering to and multiplying the filter cloth, and when the liquid passes between the fibers of the filter cloth, the liquid is sterilized and purified.

[0013]

[Effect of the Invention] The filter cloth of the present invention is a synthetic fiber having antibacterial properties.
A plain yarn of a round yarn and a flat yarn, and
The band-shaped hard cloth placed parallel to the hand direction has antibacterial properties.
Since the suture integrally superposed webs, along with web filtration function, Ru can bent into a predetermined shape by strength and shape retention of the hard eyes of the fabric. Especially the width along the texture
Can be easily bent in any direction, and the bent shape is retained.
Thus, it can be folded back alternately and can be easily attached to a filter or the like in the form of a bellows . In addition, since both the hard cloth and the web have antibacterial properties, it is possible to prevent the bacteria from propagating and propagating on the filter cloth and generating an offensive odor, and it is not only hygienic but also a liquid to be filtered. A bactericidal action against can be expected.
