a) Water-soluble fiber for papermaking PVA, which is formed by the hydrogen bonds between the free hydrocarbyl groups in the molecule and the pulp fibers, and because the strength of the water-soluble fiber is much higher than that of any pulp fiber cone, plus the semi-fusible and sticky properties during processing. The knot effect greatly increases the elongation, tearing strength, tensile strength, folding endurance and printing surface strength of the finished paper, without affecting the ink absorption performance of the paper.
Poorer papermaking pulps (waste pulp, straw pulp, wheat straw pulp, eucalyptus pulp, etc.) can be used to produce higher-quality paper, which greatly reduces raw material costs. The same pulp can also be used to reduce the paper ration (1 to 3% of the fiber added can reduce the quantification of the paper by more than 15%).
b) Adding paper-made PVA water-soluble fiber to produce paper of the same quality can greatly reduce the amount of wood pulp added, reduce wood consumption, and meet environmental protection requirements for sustainable development.
c) Paper-making PVA water-soluble fiber has excellent weather resistance and does not change during long-term storage in sunlight or air, so it can improve the shelf life of paper.
d) The paper produced by adding PVA water-soluble fiber can be completely recycled, and its water-soluble fiber can be naturally biodegraded in water after being dissolved in water, without any pollution to the environment.
e) Adjusting the papermaking PVA water-soluble fiber in the fully dissolved or semi-dissolved state in the papermaking process can change the permeability of the finished paper.
