Abstract: Regenerated cellulose fiber is the most widely-used and most variety of cellulose fiber. Five categories and ten kinds of fibers such as lyocell fiber, viscose fiber, modal fiber, bamboo pulp fiber, and sheng-bast fiber were chosen as the research object. The sectional shape, crystallinity and degree of polymerization of fibers were tested and analysis, to explore the nature of the reasons for the formation of fiber performance difference, and to verify through experiments.

Abstract: The citations to articles published in Applied Physical Letters (APL) and Journal of the American Ceramic Society (JACS) were analyzed. For each journal, 199 articles published in 1995 were randomly selected and the number of citations in each year, CY, to these articles during 1996 ~ 2004 were recorded. It was found that CY reaches its maximum in 1997 for APL and in 1999 for JACS. During the first three years after the year when the articles were published, the number of self-citations to the articles published in APL is about two times of that in JACS. These results seem to indicate that the impact factor, which is defined as the ratio of the number of citations to a journal to the number of articles published in this journal over a two-year period, is not comparable for different journals in different fields.

Abstract: Tencel fiber is an environmental friendly regenerated cellulose fiber generated using solvent spinning method, which has been widely used in recent years for its good wearability. The experiment of moisture absorption and release properties was carried out in standard atmospheric conditions for different kinds of tencel fiber in this research, and then moisture absorption, moisture release, moisture absorption rate and moisture release rate regression curves were established and compared with those of ordinary viscose fiber. The results showed that the moisture absorption and release properties of different tencel fiber were different for their different processing processes. The moisture absorption equilibrium regain of tencel LF is 8.89%, tencel A100 is 11.44%, and tencel G100 is 10.33%. The moisture absorption ability of tencel A100 is the best, tencel G100 is the second, and tencel LF is the third. The moisture release equilibrium regain of tencel LF is 10.66%, tencel A100 14.12%, and tencel G100 11.47%. Moisture absorption, moisture release, and their rate regression curves are all close to exponential curves.
