Description

[Detailed Description of the Invention] [Field of Industrial Application] The present invention provides a Pento/II deodorizing sheet suitable for treating excrement and urine of dogs, cats, rabbits, and other small animals, and for spreading on small H4. It's about configuration.

[Conventional technology]

Sheets like the one shown in Figure 3 have traditionally been placed at the bottom of toilets and small animal cages where dogs, cats, and other small animals kept as pets at home use their feces and urine.

As shown in the figure, one sheet of deodorant sheet is 21 φ22...
・ is stacked on top of each other, with water-absorbing resin powder 3 interposed between them (
[[5] Even 1 has a structure in which a waterproof film 41 is attached to the back side and a non-woven #5 for reinforcement is bonded to the surface. Also, as a deodorizing agent, for example activated carbon powder, chlorophyll.

Deodorizing sheets with zeolite powder sandwiched between sheets of paper have also been reprinted.

[Problem that the invention seeks to solve]

■: The conventional deodorizing sheets described above are not very strong because they are made of 1. several sheets of laminated paper 21, 22, etc.; If a large amount of urine is absorbed, it will be difficult to handle even if there is waterproof Fill-No-4 and non-woven fabric 5 that have been pasted on for reinforcement. In addition, since urine is simply absorbed by the water-absorbing resin, the body is full of discomfort. When the adsorption capacity of activated carbon powder, which is used to remove unpleasant odors, becomes saturated, there is a problem that the deodorizing effect cannot be obtained and the sustainability of deodorization is poor.

To provide a deodorizing sheet for pets which solves the problems mentioned in the above and has a deodorizing function having an activity of decomposing the bad odor generated from excrement into odorless components.

[Failure to solve the problem]

-1. Deodorizing sheets for pets to which the present invention is applied to solve the above problems will be explained with reference to FIG. 1 corresponding to an embodiment. As shown in the figure, the deodorizing sheet for bed has a waterproof resin film 4 laminated on one side of a fiber M layer 6. The fiber layer 6 contains deodorizing fibers carrying metal porphyrin or a substituted 1 derivative of metal porphyrin.

[Effect]

Metal porphyrins have a central metal that donates electrons to perform an enzyme-like catalytic action, producing ammonia, amines, sulfurized water, di,
Rapidly decomposes malodorous substances such as mercaptan and skatole emitted from excrement, urine and the body.

Since the deodorant for pents described in (1)-- has porphyrins of the marten genus supported on the ja1 pheasant layer 6, unpleasant odors can be removed when placed in the toilet or shed of small animals.

〔Example〕

Hereinafter, three embodiments of the present invention will be described in detail.

FIG. 1 is a perspective view of an embodiment of deodorizing sheets for pets to which the present invention is applied, and FIG. 2 is an enlarged sectional view thereof. As shown in FIG. 1, the deodorizing sheets for pets are made by laminating a waterproof resin film 4 on one side of a fiber layer 6 and adhering or fusing it. The tlJJiM1 layer 6 is, as shown in FIG.
A needle punch 7 is applied to the dry nonwoven fabric.

A part of the fiber layer 6 is deodorizing fiber, which is a fiber that supports metal phthalocyanine, which is a type of metal porphyrin. The metal phthalocyanine can be supported on the fibers, for example, as described in (1) to (2) below.

Raw fibers, synthetic fibers, and synthetic fibers are used.

Incidentally, 1-1 +1 of the nonwoven fabric forming the fiber layer 6 can be set to - if necessary. In addition to the needle-punched fabric described in 112, the fiber layer 6 may also include a nonwoven fabric formed by mixing heat-fusible fibers as adhesive fibers or bonding mixed u&fiber webs with a binder. The fiber layer 6 is not limited to a nonwoven fabric, but may also be a woven fabric made of a blended fiber system of super absorbent fibers and deodorizing fibers, a raised woven fabric obtained by subjecting the woven fabric to a temperature rise treatment, or the like.

In addition to super absorbent fibers and deodorizing fibers, the fibers constituting the W&fiber layer 6 may be an appropriate mixture of natural or chemical fibers.

〔Effect of the invention〕

As explained above, the deodorizing sheets of the present invention have a layer containing deodorizing fibers attached with metal porphyrins or substituted derivatives thereof that have an enzyme-like catalytic action, so that they have a deodorizing effect and a long-lasting effect. Excellent sex. That is, the deodorizing agent does not absorb or store off-odor substances, nor is it consumed in the deodorizing reaction system. Therefore, the deodorizing function can be maintained semi-permanently. Conventional deodorant sheets that use activated carbon powder to absorb odor substances must be replaced once the absorption reaches saturation. In contrast, the deodorant sheets of the present invention do not need to be replaced. Therefore, when used in the toilet or shed of a small animal, the running cost can be reduced and it is practical (it has an excellent IlfI value).
