PULP COMPOSITION |
| 摘要 |
One aspect of the invention relates to a 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). Another aspect of the invention relates to an ARF pulp having ISO brightness of 60% or higher, and unexpected quality sufficient for papermaking (e.g. high strength parameters and high freeness). Another aspect of the invention relates to a pulp composition made from a pulping process comprising using a high concentration of anthraquinone (AQ). The pulping process can use wood or nonwood fibers (e.g., bagasse and corn stover) to provide pulp having good paper-making quality. |

1. A pulp composition comprising:
fibers from an agricultural renewable fiber source, wherein the pulp composition has an unbleached Kappa number of about 20 or less, a high freeness of at least about 400 mL CSF, and a tensile of at least about 5.50 km, a tear index of at least about 6.00 mN·m2/g, and a burst index of at least about 3.00 kPa·m2/g. |
