ARTICLES OF MANUFACTURE MADE FROM PULP COMPOSITION

摘要

One aspect of the invention relates to an article of manufacture made from a pulp composition comprising an ARF pulp. In one embodiment, the pulp composition made from agricultural renewable fibers (ARF) having low Kappa number with unexpected quality sufficient for papermaking (e.g., high strength parameters and high freeness). In another embodiment, the ARF pulp has ISO brightness of 60% or higher, and unexpected quality sufficient for papermaking (e.g. high strength parameters and high freeness). In another embodiment, the ARF pulp is made from a pulping process comprising using a high concentration of anthraquinone (AQ).
