Tissue is one of the hardest grades to get right. The customer wants a sheet that feels soft and soaks up water quickly, yet does not fall apart the moment it gets wet. All of that has to happen on a machine running very light basis weights at high speed.
We work with tissue and napkin producers who make toilet rolls, facial tissue, kitchen towels and table napkins. For wet strength, most of our tissue customers use urea formaldehyde resin, and switch to melamine formaldehyde or PIDIFIX 361 where they need stronger, longer-lasting wet strength, such as kitchen towels.
Where we help tissue mills
- Drainage and refining – cellulase and xylanase enzymes reduce refining energy and help the sheet drain on the wire.
- Slime and deposits – SAPCO 130-P and biocides cut down holes, spots and wash-ups.
- Foam in the short loop – SAPCO KF defoamer.
- Coloured tissue and napkins – Rhodamine, Malachite Green, Paper Yellow and Methylene Blue.
- Brightness for white grades – optical whitening agents and hydrogen peroxide for recycled fibre.
Press felts matter as much as chemistry on a tissue machine. Our endless felts from Daehan, Korea are designed for each press position so the sheet dries faster and the Yankee runs with less steam.
Tell us your grades, furnish and machine speed, and we will suggest a programme that fits.
