It is practically difficult to move to a summer resort only during the summer. For this reason, many homes that keep dogs as pets and zoos that breed Arctic bears want simple summer protection measures that do not require animals to be moved. In order to meet this demand, recently, a cushion having a water-absorbent resin put therein and absorbing water when used has been sold.

提供することにある。However, commercially available cushions containing a water-absorbent resin require several hours or more to absorb water, and the water-absorbent resin protrudes outside due to the weight of the sitting animal, and is inconvenient. Therefore, an object of the present invention is to provide a mat which absorbs water in a short time and can be used for one season.

面の水が気化するときの気化熱によっても向上する。In the mat of the present invention, the water-absorbent resin has an average particle size of 50 μm or more, and the air permeability of the cloth is 8 cm 3 / cm 2 · sec.
Since it is not more than c, the water-absorbing resin does not spill outside before water absorption. Then, since the cloth is hydrophilic, water is quickly passed through and the water is guided to the water absorbent resin. Since the water-absorbent resin has an average particle size of 1000 μm or less, it absorbs water promptly.
However, since the air permeability is 1 cm 3 / cm 2 · sec or more, the water on the surface of the water-absorbent resin and the urine leaked from the animal evaporate little by little, but do not protrude from the fiber network to the water-absorbent resin. Further, since the water absorption of the water-absorbent resin with respect to pure water is within the above range, the water-absorbing resin has sufficient cooling capacity and elasticity after water absorption, and the ratio of the water retention to pure water is as described above. Even if ordinary pets or domestic animals swirl in addition, they can withstand their weight without easily separating from water. The cooling performance is also improved by heat of vaporization when water on the surface of the water absorbent resin is vaporized.

When dyne / cm 2 , deformation of the gel due to the weight of the animal is suppressed and the elasticity is high, so that the feel is the best, which is preferable.

整することができるからである。Examples of the cloth include woven cloth, knitted cloth and non-woven cloth. Preferred is woven cloth, which has a fiber density of 200 fibers / inch or more, preferably 200 to 280 fibers / crushed after scouring. It is a blend of cotton with inch or cotton-based polyester, acrylic, nylon, etc. In the case of blending, the proportion of cotton is preferably at least 60% by mass, particularly preferably at least 70% by mass. Before scouring, cotton is hydrophobic due to dirt and the like, but is inherently hydrophilic.Hydrophilicity is exhibited by scouring, and by crushing high-density materials, the air permeability is within the above range. This is because it can be easily adjusted.

し、外布に自由に装飾できるからである。The cloth is sewn up and down so that the inner space is divided into a plurality of parts, preferably two to eight pieces, and the divided spaces are equally water-absorbing per unit area. It is good that resin is filled. Thereby, it is possible to prevent the water absorbent resin from being biased to one side in the bag.
In addition, cotton is easy to shrink, but the suture prevents shrinkage even with 100% cotton. Further, the cloth may be covered with an outer cloth having high air permeability. This is because it is mechanically reinforced and can be freely decorated on the outer cloth.

Two square-inch bleached inch cloths and two dyed cloths of the same size and air permeability of 30 cm 3 / cm 2 · sec were prepared. Then, two white cloths were placed on the inside and two color cloths were placed on the outside, and a total of four sheets were overlapped and three sides were sewn. In addition, stitching was performed on three lines parallel to the two opposing sides, and the internal space was divided into four equal parts. Each of the divided spaces was filled with 7 g of the water-absorbent resin from the unsewn side, and the sides were sewn to produce a mat with the water-absorbent resin.
