Appl. No.:

15/556867

Inventors:

- Wayzata MN, US
Brent A HAWKINS - Eurenka CA, US
Fred MARTIN - Arcata CA, US
Manoj SAHOO - Plymouth MN, US

International Classification:

D21C 3/00
D21C 3/18

Abstract:

Substantially homogeneous and stable suspensions of anthraquinone (AQ) compositions and methods of preparation are disclosed. The AQ compositions are utilized in pulping processes.

US Patent:

20150129143, May 14, 2015

Filed:

Oct 23, 2014

Appl. No.:

14/522476

Inventors:

- Wayzata MN, US
Fred Martin - Arcata CA, US

International Classification:

D21H 17/00

US Classification:

162 72

Abstract:

A pulping process comprises using a high concentration of anthraquinone (AQ). The pulping process is capable of providing a pulp having low Kappa number with unexpectedly high strength. The pulping process can use wood or non-wood fibers (e.g., bagasse and corn stover) to provide pulp having good papermaking quality. The method for pulping a fiber comprising cooking a first mixture comprising the fibers, water, an alkali, and a delignification selectivity enhancing chemical for a cooking time and at a cooking condition sufficient to form a first pulp having a desired Kappa number of about 15 or less, and strength parameters that are sufficient for papermaking, where the starting material prior to cooking has a Kappa number of 60 or greater.

D21C 3/00
D21H 17/00

US Classification:

162 96, 1621814, 1621813

Abstract:

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.

US Classification:

162150, 1621814, 1621813

Abstract:

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).
