  • Patent number: 9976001
    Abstract: Provided is a process for producing a water-absorbing resin powder which contains a given amount of water added thereto, has a low dust content, and has high material properties. When a water-absorbing resin powder which has undergone surface crosslinking is produced on an industrial scale, various problems concerning production are eliminated and a long-term stable operation is possible without causing a deterioration in the material properties of the resin. Even when the process is continued over a long period, the material properties are stabilized (decrease in standard deviation) or improved (improvement in AAP). The process for producing a water-absorbing resin comprises, in the following order, a first classification step for classifying a water-absorbing resin, a surface crosslinking step after the classification, a water addition step for adding water to the water-absorbing resin powder after or during the surface crosslinking, a second classification step, and a conveying step.

  • Patent number: 9334597
    Abstract: Repeatable and reliable chemical treatment for loose fibers is achieved by spraying or immersing loose fibers in a chemical treatment bath, and continuously moving the soaked fibers through a continuous centrifuge. The continuous centrifuge controls the wet pickup of the chemical formulation on the fibers and assures a substantially even chemical distribution on the centrifuged fibers. The centrifuged fibers may be dried to fix the chemicals in the chemical formulation to the fibers and/or to remove water from the chemical formulation. Recycling of the chemical formulation from the continuous centrifuge allows for the process to be performed more economically and in a more environmentally friendly fashion.
