Viscose fiber characterization

Fiber characterization such as linear density, fiber strength or tenacity and elongation of staple fibers and filaments from viscose and particle size show the condition of the fiber.


RISE is equipped with two instruments for determining, among other things, linear density, fiber strength or tenacity and elongation of staple fibers and filaments from viscose. Spin studies based on viscose solution from dissolving cellulose, either manufactured in our pilots or delivered from customers, can be done in our spin pilot after which the final viscose fiber is characterized. The most common analysis is done on dry fiber, but even wet fiber can be analyzed.


The instruments are partly a Vibrodyn 400 and partly a Vibroscope 400 from Lenzing Instruments. The determinations are based on the methods SS-EN ISO 5079, ISO 1973: 1995 (E) and ISO 1130-1975 (E).

Viscose plant - development of dissolving cellulose

To develop and optimize regenerated cellulose, RISE has two viscose pilots, one on a micro scale and one for larger volumes of viscose solution. The pilots consist of six parts which together correspond to an actual manufacturing …

Spinning pilot - manufacture thread on a lab scale

Increased population in the world results in increased consumption of textiles. This means that the textile raw material needs to be optimized and its process developed to make them more sustainable so that the consumption of the …

Molecule weight distribution

RISE can characterize pulp, carboxymethylcellulose, polyacrylate, starch, biocides, lignin, black liquor, hemicellulose.

Analyzes of pulp for dissolving

To see if a cellulose pulp is suitable for dissolving, it needs to be characterized and tested, which RISE can help you with.

Light microscopy quickly shows small details

With light microscopy, you can quickly get an overview of the problem and all images are displayed in color. It is often used in connection with product development, problem solving and support to end customers. To gain an underst…

Scanning electron microscopy sees surface structure and elements

Processes are often warm and humid that create good environments for bacteria, precipitates and other undesirable phenomena that contribute to disruption and degradation of end products. Scanning electron microscopy (SEM/XDS) has …

Gas chromatography-mass spectrometry identifies many materials

Materials and processes need to identify their products. Using gas chromatography-mass spectrometry facilitates the work and it is often used in connection with problem solving and environmental issues. The instrument is very usef…
