  • Patent number: 10362763
    Abstract: An excrement-treating material includes a water-absorbing core part, and a surface layer. The core part is formed by wet-kneading and compression-granulating a compounding material containing a paper powder and organic or inorganic fine pieces. Dents and/or protrusions are formed on the surface of the core part by deformation by the kneading or compression of the fine pieces or peeling-off of the fine pieces from the paper powder upon release of compression. The surface of the core part is discontinuously colored by utilizing the dents and/or protrusions, and covered with the surface layer. The colored parts of the surface of the core part are exposed through the surface layer during absorption of excreted urine, while the non-colored part of the surface of the core part is stained by the color of the excreted urine, and the color of the excreted urine is exposed through the surface layer.

  • Patent number: 10065356
    Abstract: A method of producing granular excreta treating material utilizes an extrusion type compressive granulating apparatus configured to produce granular excreta treating material that has an absorbing property and is formed by extruding and granulating a raw material via a granulating hole of the apparatus. The granulating hole includes a small diameter hole and a large diameter hole which are continuous to each other in the axial direction of the hole, in which the small diameter hole forms a compression zone, and the large diameter hole forms a non-compression zone, and in which the raw material is compressed at the compression zone, swells at the non-compression zone, and is cut into granules by a cutting blade rotating along an outlet surface of the non-compression zone.

  • Patent number: 9743637
    Abstract: An excrement-treating material has a core part, and a surface layer bonded to the core part by utilizing the adhesion ability of a water-absorbable polymer in the surface layer without using an adhesive. The excrement-treating material suitably exerts the water absorbability and water transport ability inherent to the surface layer. The excrement-treating material is constituted by incorporating pulverized water-absorbable polymer particles of 20 ?m to 50 ?m, and adding water to the surface of the core part after granulation to noncontinuously form a highly-wet part; reacting a water content in the highly-wet part and the pulverized water-absorbable polymer to noncontinuously form an adhering part; and bonding the surface layer to the core part through the adhering part. Upon absorption of excreted urine, permeation of the urine into the core part is accelerated in a part other than the adhering part.

  • Patent number: 9504229
    Abstract: The present invention provides a floor material for pet animal urination, which has an effect to allow urine to pass through by suppressing speed and amount of urine absorption, as well as an effect of low water absorbency allowing to gradually absorb residual urine sweating the grain surface, which also has good shape retentivity so as not to be collapsed even if urine is absorbed, and thus which is highly suitable as a floor material for pet animal urination. There is provided a floor material for pet animal urination, wherein a surface of each of water-absorbing grains (1?) is coated by a slow water-semipermeable coating (6); and because of the slow water-semipermeable coating (6), urine is prompted to pass between the water-absorbing grains, and residual urine (8) sweating the surface of the water-semipermeable coating (6) is gradually absorbed into the water-absorbing grains (1?) through the water-semipermeable coating (6).

  • Patent number: 7066110
    Abstract: Moisture absorbing efficiency of excrement is enhanced by providing a high degree of porosity and a high porosity ratio to a hydraulic granulated body and a non-hydraulic granulated body in a method of manufacturing a granulated body for absorbing excrement of animals. There is provided a method of manufacturing a granulated body for absorbing excrement of animals, characterized in that dry bamboo fibers and wood fibers are used as a chief material. The dry bamboo fibers and wood fibers are mixed with each other while adding moisture thereto and the dry bamboo fibers are allowed to absorb the moisture. The resultant is granulated to form a wet granulated body, hot air is blown to the wet granulated body, and the moisture absorbed in the dry bamboo fiber is transpired outward through the wet granulated body by the hot air. A porous structure in the dry bamboo fibers in the wet granulated body is produced by the transpiration due to formation of transpiring paths in the wet granulated body.

  • Patent number: 7028637
    Abstract: A discharged-waste processing material for pet animals is formed from a waste material of double sided water resistant paper as a raw material. A chief material of the discharged-waste processing material is crushed paper pieces obtained by finely crushing the double sided water resistant paper having laminate layers on both sides. A granular body is formed of an aggregate of the crushed paper pieces and has voids formed between the laminate layers of adjacent crushed paper pieces for guiding discharged urine into a core part of the granular body. The granular body has a water retaining structure in which the discharged urine is absorbed into a paper layer between the laminate layers through a sheared surface of each crushed paper piece, and the absorbed urine is cut off by the laminate layers so that the urine is retained in the paper layers.
