Anisotropy of swelling of jute

Authors


Abstract

The use of swelling anisotropy as a means of determining the orientation of cellulose fibers has been critically reviewed, and it has been shown that the method should be suitable for highly oriented fibers within a certain range of orientation. The application of the method to untreated and variously treated jute fibers reveals certain structural differences with ramie, of which the following are noteworthy. Both noncrystalline and crystalline orientations of jute are influenced by treatments which can be regarded as being confined to the intercrystalline regions only and which do not affect ramie. As compared with ramie, the ultimate maximum disorientation, produced on mercerization treatment is markedly less in jute, and this holds for both the crystalline as well as the noncrystalline components of the fiber.
