The Impact Factor measures the average number of citations received in a particular year by papers published in the journal during the two preceding years. 2017 Journal Citation Reports (Clarivate Analytics, 2018) IF: 1.7 To calculate the five year Impact Factor, citations are counted in 2017 to the previous five years and divided by the source items published in the previous five years. 2017 Journal Citation Reports (Clarivate Analytics, 2018) 5-Year IF: 1.4 The Immediacy Index is the average number of times an article is cited in the year it is published. The journal Immediacy Index indicates how quickly articles in a journal are cited. Immediacy Index: 0.6 The Eigenfactor score, developed by Jevin West and Carl Bergstrom at the University of Washington, is a rating of the total importance of a scientific journal. Journals are rated according to the number of incoming citations, with citations from highly ranked journals weighted to make a larger contribution to the eigenfactor than those from poorly ranked journals. Eigenfactor: 0.00072 The Journal Citation Indicator (JCI) is a single measurement of the field-normalized citation impact of journals in the Web of Science Core Collection across disciplines. The key words here are that the metric is normalized and cross-disciplinary. JCI: 0.43 SJR: 0.318 SNIP: 0.568 CiteScore™:: 3.5 H-Index: 28

SINOPSIS

This research simplified the yarn bobbin as a hollow cylinder and treated it as a porous medium, then established a model of mass transport which considered not only diffusion but also capillary flow. The basic properties of four samples are determined by experiments, e.g., the porosity and permeability. The capillary force equation of the imbibition process (Leverett function) was determined by centrifugation. The relative permeability of the liquid phase was obtained based on comparison between calculation results and experimental data. The effective diffusivity was analyzed based on the effects of diffusion and capillary action, its value depending very much on the permeability, temperature, and so on. Meanwhile, the calculation results revealed that there is a critical temperature for the transport process, when the temperature is lower than the critical value, with an increasing temperature being beneficial to mass transfer. Proper reduction of the diameter of yarn bobbins is a method to enhance the mass transport process.
