Abstract:

In order to prepare cellulose diacetate (CDA) from burley tobacco stalk pulp (TSP) and measure its spinnability, cellulose triacetate (CTA) and CDA were prepared from burley TSP by low-temperature acetylation using acetic anhydride and sulfuric acid as catalyst. The prepared CDA was mixed with commercial CDA at a mass ratio of 20∶80, 35∶65 and 50∶50, respectively, and electrospinning was applied to spin the fibers. The structure and properties of the fibers were characterized. The result shows that with reaction time of 5 h, pulp to acetic acid sold-liquid ratio of 1∶5 and addition of sulfuric acid during activation procedure, the degree of substitution of TSP cellulose acetate increases from 2.68 to 2.86, which meets the requirements of CTA. TSP cellulose diacetate with degree of substitution about 2.5 is obtained by hydrolysis at 80 ℃ for 6 h. Compared with sub-micron blended fibers obtained from pure electrospun commercial CDA, the fiber diameter and unevenness of blended fibers of TSP cellulose diacetate and commercial CDA both reduce, proving the feasibility of blended spinning of TSP cellulose diacetate.

Key words: cellulose acetate, tobacco stalk dissolving pulp, acetylation, hydrolysis, electrospinning
