Starting with the basic components of a sheet of hygienic paper, we will look at what these are & how they are transformed by the papermaking process (from pulping through to finishing & converting) into the hygienic product that the consumer experiences.
A focus is placed on how quality can be enhanced & controlled through each of these stages.
At the end of the day we will begin looking at the properties of a sheet of hygienic paper & how they are interrelated.
Fibres: the basics, the different types, how they impact on final sheet properties
Pulping: a look at the major types of virgin fibre pulping techniques, & secondary fibre treatments
Papermaking: a guide through the papermaking process, from pulp preparation & approach flow through to the end of the paper machine
Chemical Additives: talking through the most common categories of chemical additives used through the tissue making process
Finishing & Converting: from the parent reel-up to the customer - what processes are likely to be involved in turning a parent reel into saleable tissue
A closer look at Tissue properties will then lead us into a focus on the Yankee Cylinder – how we can protect & use this critical part of the tissue machine to develop the best quality for any given grade of tissue.
We will end our session with a look at softness. Specifically we will discuss the definition of, the measurement of & finally our options to enhance the softness of our tissue products, where applicable.
Tissue Properties: identifying what properties are desirable in different types of hygienic paper, looking at how our manufacturing processes impact on these. Is it possible to enhance all our properties together? Or are there trade-offs to be considered?
Focus on the Yankee Cylinder: A look at Yankee performance & operation. Where to look when trying to trouble shoot the root cause of issues that may be seen & experienced at the Yankee
Considering Quality: What does “quality” mean to each of your customers throughout the process? How can we influence final sheet properties right from the start of the process? Look at root cause issues of quality defects
Softness: looking at softness in a logical progression, from the definition of softness, through to how it is measured & finally looking at ways to enhance softness perception through papermaking processes
There will be a visit to a tissue mill, Fapajal in Loures, during the morning of 18th may, for all attendees that wish to see in site the theoretical knowledge provided in the last two days.
This course is essencial training for anyone (manufacturer or supplier) new to the Tissue Sector or those wishing to broaden their understanding of this fascinating paper product.
