Fluff pulp

With an increased population, sanitary products are used to a greater extent. Producers for fluff pulp can at RISE optimize and develop the process and product, both for the environment and the user, and performing a quality assessment of the original pulp can be part of that work.

At RISE, there is a long experience of the processes (cooking and bleaching) that are used to produce fluff pulp and expert knowledge of fibers as it is important to choose the right type of fiber to get the best properties of the pulp.

RISE has a unique chain of pilots to conduct studies all the way from the raw material to the finished fluff pulp from chipping, boiling, bleaching and evaluation of the properties via a well-equipped analysis lab. In addition to the purely process technical, RISE can help with the evaluation of the specific analyzes that are used to make a quality assessment of fluff pulps. For example, the fiber dimensions are usually analyzed where coarse fibers generate high volume and bulk, long fibers give good network strength, low proportion of fines and high proportion of fibers favor a high-quality fluff pulp. These fiber analyzes can be studied under a microscope and with advanced measurement technology in fiber analyzers.

Furthermore, energy consumption via experiments in a hammer mill and subsequent knot number measurement are important properties that are evaluated on fluff pulp. In addition, dry forming can be performed to produce the small pads which are then used to analyze absorption properties. A complete physical test can of course also be performed to evaluate the physical properties of the mass.

We always work in close dialogue with our customers to ensure value.
