It develops environmentally protective water suction lining paper product and has a vast market development space.
Since the quality requirement of the water suction lining paper of production is higher, insider thinks the best raw material of lining paper that absorbs water at present
It is bleached softwood wood-fibred.And China's wood raw material is by cultivated area, growth cycle, the ecological balance, production cost and environmental protection
Etc. the constraints of factors lead to its limits throughput so that domestic wood fiber raw material supply is difficult to meet in the future for a long period of time
The raw materials requirement of relevant industries.Existing bleached wood pulp is mostly import, and larger cost of material pressure is brought to domestic relevant industries,
For these reasons, the new type natural of suitable China's national situation, renewable cellulose fibre how to be developed to make up wood raw material
It is insufficient；How by the improvement of preparation flow and technology and equipment etc., the quality for preparing high added value conforms to
