Latest Patents

Yichao Lei holds a patent titled "Method for preparing fluff pulp from bamboos and fluff pulp prepared thereby." This patent discloses a method that involves treating bamboos with high-concentration alkali at a relatively mild temperature. After a specific treatment period, the method replaces the treatment liquid for separating hemicellulose with a weak black liquor. The process continues with Kraft cooking the treated bamboos to obtain unbleached bamboo pulp, followed by the removal of rejects using a slotted screen. Miscellaneous cells are eliminated using a microporous sieve, and two stages of oxygen delignification are carried out on the screened pulp. The final steps include ECF bleaching treatment of a DEpDP process, resulting in bamboo fluff pulp characterized by high whiteness, low DCM extract content, low ash content, and long fiber length. This pulp contains 4.2-4.6 million fibers per gram and exhibits relatively high bulkiness.
