Abstract
A high-transparence fiberglass paper includes vegetable parchment which is successively coated with a base layer, a second layer and a protective layer on both sides. The base layer and protective layer are prepared using water-based paints, while the second layer is prepared using UV ink through curing. The transparency and surface smoothness of the fiber is thereby greatly improved. Through treatment on the both surfaces, the paper can be processed into a light and smooth paper, with a surface smoothness of both sides more than 200 s, just like hyaline paper.
