Studies on fiber morphologies of domestic and imported paper-process reconstituted tobacco

The fiber morphologies of domestic and imported paperprocess reconstituted tobacco were studied in this paper.The results show as follows:(1) There are too many motley cells in both domestic and imported products,which is conducive to the strength of product;(2) Beating does good to fibrillation,increasing the softness of fiber and its bonding s?trength,however,beating can also make the cell wall rupture,with a lot of pectin;(3) The fiber length,fiber width and ratio of fiber length to width of imported product are 1.25 mm,21.0 μm,and 59.8 respectively;The fiber length,fiber width and ratio of fiber length to width of domestic product are 1.67 mm,34.7 μm,47.8 respectively;(4)The tensile index and burst index of paper-process reconstituted tobacco are obviously not as good as triploid of populus tomentosa and Populusxiaohei;fiber length,fiber width,and ratio of fiber length to fiber width can not characterize the physical properties of the paper-process reconstituted tobacco.
