Abstract
The present invention relates to a method for manufacturing a 3-dimensional shaped product from a fluff pulp material and such product. The method according to the invention comprises the steps of: providing a fluff pulp material; providing an air-laid flow of fluff pulp material to a 3-dimensional shaped mould; forming the product in the mould; and releasing the 3-dimensional shaped product from the mould.
Claims13
A method for manufacturing a three-dimensional shaped product from a fluff pulp material, the method comprising:
- providing a fluff pulp material;
- providing one or more additives to the fluff pulp material;
- providing an air-laid flow of fluff pulp material;
- compacting the air-laid flow of fluff pulp material;
- providing the compacted flow of fluff pulp material directly to a three-dimensional shaped mould;
- shaping the fluff pulp material in the mould;
- and
- releasing the three-dimensional shaped product from the mould,
- wherein compacting the air-laid flow of fluff pulp material increases the strength of the three-dimensional shaped product released from the mould,
- wherein the one or more additives comprises a biodegradable aliphatic polyester in the range of 0.5-20 wt %, and
- wherein biodegradable aliphatic polyester is polybutylene succinate (PBS).
