Analyzes of Cellulose for Dissolving Pulp

By using dissolving pulp as a raw material, textile companies can play an active role in the transition towards a more sustainable and circular economy. By investing in research and development of dissolving fibers and production methods, the industry can contribute to promoting a more sustainable future for textile production and consumption.


The quality of dissolving pulp is crucial for the resulting fiber's properties, such as strength, elasticity, and color fastness. Therefore, it is important to carefully characterize and test the pulp before it is used in the production process to ensure that it meets specific requirements and standards for the intended use.

RISE has extensive experience and expertise in the characterization and testing of dissolving pulp and can assist companies in the textile and cellulose industries in evaluating and optimizing their raw materials for the production of high-quality fibres and products.

In the viscose pilot plant, along with the analyses mentioned below, individual pulps, as well as the suitability of various cellulose blends for viscose production, can be evaluated. Screening experiments can be conducted to investigate the influence of different process parameters on various dissolving pulps and to test how well a cellulose performs under given process settings. It is also possible to evaluate different process chemicals, test various additives for fibre properties, and so on.

Common pulp analyses:

  • α-, β- och γ-cellulose – A widely used course measurement of the distribution of the degree of polymerisation (DP) of the pulp. High values of α-cellulose is seen as favourable.
  • Acetone Extract – Low content of material extracted with acetone is favourable, but constant levels can be more preferable to ensure stabile processing. Many surface active additives will show up here.
  • Carbonhydrates –Characterisation of the sugar moieties of which the pulp consists, which provides information about e.g. the hemicellulose content.
  • Ash content – Measurement of the inorganic content in the pulp.
  • Metals (Ca, Mg, Mn, Fe, Cu) – Measurement of the metal content in the pulp (specifically those found to have effect on the processability).
  • SiO2 content –Often measured on pulps to ensure levels are below a set threshold, as too much silica can disturb the spinning.
  • Lignin content (Klason or acid soluble) – Measurement of the lignin content of the pulp.
  • Molecule weight distribution
