MoRe Research very interesting and useful experimental paper machine for tissue
Evaluate our pulp:
When evaluating the suitability of different pulps for paper production, it is not correct only to rely on conventional pulp testing – a paper product must be produced. For this purpose MoRe Research have developed the pulp suitability test (PST). Development work within the tissue area is one example where PST can be a useful tool as it is possible to produce creped paper using small amount of pulp – minimum 2-3 kg.
The first step of a PST-Tissue is a runnability trial on the paper machine, including measurement of the adhesion force to the Yankee cylinder, dewatering and dry solids of the paper web.
Creping of the paper is performed with or without adhesion or realease chemicals depending on the results of the runnability tests and the aim of the trial. Several parameters such as pick-up vacuum and Yankee temperature can easily be tested.
PST-Tissue can be used for different purposes:
- Benchmarking of several pulps regarding tissue properties and runnability
- Effect of additives
- Runnability/optimisation trials: process parameters such as pick up felt vacuum and Yankee temperature, pulp (refining, pulp mixture...)
Depending on the purpose of the trial, different analyses can be performed:
Runnability:
- Adhesion force on the Yankee cylinder
- Solids content
- Level of creping
- Beatability (Escher-Wyss refiner)
Tissue properties
- Softness
- Dry and wet strength
- Absorption speed
- Level of creping
- Thickness, density
Uncreped paper
- Beta formation
- Topography
- Dusting tendency
Pulps
- Chemical properties
- Fibre morphology
- Physical properties
