Abstract

The invention discloses a chromatography super-flexible piezooptical paper and copying-making technology, which is characterized by the following: adopting bleached sulfate coniferous paddle(NBKP), pasta alkaline hydrogen peroxide thermomechanical pulp (PRC-APMP) and wastepaper void pulp (DIP); adapting copying-making technology after beating; calendaring; applying glue and super-piezooptical ornament on the surface to reach the specific technological index need of paper print with 48.5+-1g / m2 quantity, 6-8 percent moisture, 68-70 percent whiteness (ISO), more than 87 percent nontransparency, more than 4500M fraction longitudinal direction.

Description

1. Technical field [0001] The invention relates to a color printing super soft calendered paper and a papermaking process thereof. 2. Background technology [0002] In my country, the magazine and periodical industry has generally shown a growth momentum over the years. In 2004, a total of 9,490 periodicals were published nationwide, with a year-on-year increase of 4.58%; the total number of printed sheets was 11.051 billion, equivalent to 259,700 tons of paper. According to the analysis of China Light Industry Information Center, the substitution effect of the Internet on magazines, books and commercial (product) catalogs is relatively slow. On the contrary, the development of the Internet has stimulated the further expansion of the commercial (product) catalog market, and it is expected that a large number of new magazines will emerge in the next 10-15 years. As far as the current situation is concerned, as the most important magazine paper, super calendered paper (SC pap...
