  • Patent number: 8857195
    Abstract: An absorbent adapted to be used in a spray can charged with a liquefied gas, which exhibits excellent absorbing performance and excellent liquid retention. The absorbent is composed of an assembly of pulverized cellulose fibers that includes at least 45 mass % of fine cellulose fibers having a fiber length of 0.35 mm or less. The absorbent is formed into a sheet-shaped or a columnar configuration, or a surface sheet is laminated on a surface of the absorbent. The absorbent composed of 70 through 90 mass % of cellulose fibers that include 45 mass % or more of fine cellulose fibers having a fiber length of 0.35 mm or less, and 5 through 30 mass % of a fusion-bondable resin exhibits good formability.

  • Patent number: 8822552
    Abstract: A spray can product capable of preventing leakage where used or stored in a tilted or an inverted position, and keeping good safety and liquid retention even where a flammable liquefied gas is used. The spray can product is formed by filling a spray can having an ejection opening with a liquefied gas and an absorbing body for retaining liquid, and the absorbing body is composed of an assembly of cellulose fibers containing at least 45 mass % of fine cellulose fibers having a fiber length of 0.35 mm or less. The absorbing body compressed into a block-shaped configuration corresponding to that of the spray can is accommodated within the spray can while defining a space on the side of an ejection opening, and a lid-like member is provided between the space and the absorbing body to protect a surface of the absorbing body in a gas permeable manner.

  • Publication number: 20100282621
    Abstract: A high-quality spray product that uses a less expensive propellant exhibiting a lower ozone-depleting potential and a lower global warming potential without using any fluorocarbon, any alternative thereto, etc., and exhibits an improved safety and an improved liquid retention. A dust blower as the spray product uses a propellant composed of a mixture of dimethyl ether and carbon dioxide, and an absorbent adapted to retain the propellant, which is composed of an assembly of pulverized cellulose fibers such that the cellulose fibers include at least 45 mass % of fine cellulose fibers having a fiber length of 0.35 mm or less. The propellant and the absorbent are charged in a spray can having a spray nozzle, thereby preparing a dust blower.

  • Publication number: 20020042237
    Abstract: Disclosed is a liquid absorbing body and a method of manufacturing the liquid absorbing body which has an excellent swelling property and absorbed liquid holding ability in a vertical state and which is suitable to a mass production at a low manufacturing cost. This liquid absorbing body includes natural cellulose fibers and/or synthetic fibers, a thermally fusible material and a thickening material. This liquid absorbing body is formed by defibering natural cellulose fibers and/or synthetic fibers, a thermally fusible material and a thickening material in air and mixing them to form a mat, heating thus formed mat at a temperature higher than a fusible point of the thermally fusible material and then fixing the thickening material in a web by compressing the mat with a press roller.
