Fibre Dimensions Important for Pulp Quality

Characterizing pulp often involves a thorough analysis of the fibre composition using a fibre analyzer to control the quality of the pulp. This process is of great importance both in research projects and development projects within process and product development.

Fibre Dimensions

Fibre analysis is a critical component within the pulp and paper industry as it provides insights into the composition and characteristics of the pulp. By carefully examining fibre length, diameter, curl, coarseness, and other properties, one can assess the performance and suitability of the pulp for various applications. Fibre analysis also offers valuable information about the pulp's processability, sheet forming characteristics, as well as its ability to hold together and produce a high-quality end product.

In research projects, fibre analysis is used to explore new materials and processes, as well as to understand how various factors affect the properties of the pulp. This may involve studying the effects of different chemicals, temperatures, or mechanical treatments on fibre structure and, consequently, pulp quality. This knowledge is crucial for developing more efficient and sustainable production methods and improving product performance.

Similarly, fibre analysis is an indispensable part of development projects within process and product development. By continuously monitoring and analyzing fibre properties, potential areas for improvement in the production process can be identified and measures can be taken to optimize the quality and efficiency of the pulp. This is particularly important for meeting market demands for high-quality products and ensuring the company remains competitive in the long run.

RISE conducts numerous projects involving various types of raw materials, which place high demands on the fibre analyzer. After a mild delignification of the material, for instance, we can measure wood and annual plants as raw materials. Subsequently, we naturally utilize the analyzer to examine pulps after different process steps in the mills, as well as equivalent pulps produced in the laboratory.

The most common fibre properties include fibre length, fibre curl, fibre coarseness, and fibre width, as well as fines such as shives and kinks. It's also possible to obtain distributions of each property, serving as a kind of fingerprint for the pulp.


The PulpEye Fibre Analyzer is an advanced and high-performance analysis unit utilized in the pulp and paper industry to characterize and analyze fibres. It is designed to provide detailed information about fibre properties and composition, which is crucial for assessing the quality and performance of pulp.

One of the key features of the PulpEye Fibre Analyzer is its ability to measure multiple parameters simultaneously, offering a quick and comprehensive overview of the pulp's composition. This simultaneous measurement enables an efficient and accurate analysis process, saving time and resources for manufacturers.

By employing various advanced techniques such as image analysis and light scattering methods, the PulpEye Fibre Analyzer can measure properties such as fibre length, fibre width, fibres with different qualities (e.g., primary and secondary fibres), fibre curl, fibre coarseness, and the distribution of fines such as shives and kinks. Additionally, the unit can generate detailed reports and diagrams that present the results in an easily understandable manner.

Another advantage of the PulpEye Fibre Analyzer is its flexibility and adaptability to different production environments and requirements. The unit can be integrated into existing processes and control systems and can be used both in laboratory settings and directly on the production line to monitor and optimize pulp quality in real time.

By providing a fast, accurate, and versatile solution for fibre analysis, the PulpEye Fibre Analyzer plays a vital role in supporting manufacturers in the pulp and paper industry to ensure high-quality production and enhance efficiency in the production process.
