Abstract:
In order to improve the quality of cigar wrapping paper, the paper-base of ligneous fiber was coated with tobacco extract. The parameters of pulping and the addition rate of combustion improver, potassium citrate, were optimized. The results showed that the optimal parameters were:the pulping degree and blending ratio for unbleached softwood pulp, bleached hardwood pulp and bleached flax pulp, 80 °SR, 70%; 40 °SR, 20% and 70 °SR, 10%, respectively; the rate of potassium citrate, 10%; and the coating rate of tobacco extract, 10 g/m
2. Under that conditions, the values of
L*,
a*,
b* and chromatism of the prepared paper were 50.72, 13.68, 36.18 and 0.39, respectively; and its tensile strength, air permeability, elongation rate and smoldering rate were 1.69 kN/m, 60.84 CU, 3.13% and 149 s/150 mm, respectively; which met the technical and industrial production requirements for cigar wrapping paper. And the results of cigarette sensory evaluation indicated that comparing with common cigar wrapping paper, the prepared paper featured lower offensive odor and irritation and better the amount of aroma and harmony of cigar smoke.
