Material
Chemical pulp
Chemical pulp is produced either from softwood or hardwood. The wood chips are boiled together with chemicals and the major part of the lignin is removed. Chemical pulp is bleached in order to achieve a clean, bright and strong product, but also to increase the hygienic and absorbent qualities.
There are two major bleaching methods: ECF (elementary chlorine free) and TCF (totally chlorine free).
ECF is based on oxygene, chlorine dioxide and hydrogen peroxide. TCF is based on hydrogen peroxide and ozone.
Viscos layer
Approximately 12% of the material consist of a viscos layer which is made of regenerated
pulp and is biodegradable. It is renewable.
Chemicals
Both functional and process chemicals are used. The main functional chemicals are wetstrength and drystrength agents, dyes and softeners.
The wetstrength agent is a polyamide (from polyamidine/epichlorhydrinepolymer) with a very high affinity to the fibre, which gives the product its high wetstrength.
Process chemicals are retention agents, creping agents, defoamers, coating agents, nutrients, pH-regulators, cleaning agents, releasing agents and flocculation agents.
No dyes are used.
