Hemp viscose fiber and preparation method thereof

Fuente: WIPO "hemp"
The invention provides a preparation method of a hemp viscose fiber. The method comprises the following steps: 1) preparing a raw material: uniformly cutting root bast fibers and the tip bast fibers of hemp to prepare the raw material; 2) preparing hemp pulp: cooking and beating the raw material obtained in step 1), and washing and pulping the obtained pulp to obtain a hemp pulp; and 3) preparinghemp viscose fiber: impregnating, aging, sulfonating, dissolving, ripening, spinning, drawing, refining and drying the hemp pulp obtained in step 2) to obtain the hemp viscose fiber. The preparation method of the hemp viscose fiber is obtained by correspondingly improving assistants and concrete processes based on a traditional viscose fiber production technology for the component characteristicsof the hemp, so the preparation method is suitable for producing the hemp viscose fiber, and ensures the production effect and the product quality of the hemp viscose fiber.
