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: 1.4 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: 1.3 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: 2.2 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: 0.00034 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: 0.46 SJR: 0.333 SNIP: 0.606 CiteScore™:: 3.1 H-Index: 31

摘要

The article concerns the ventilation aspect of biophysical comfort. In the paper, multilayer textiles (built of three layers of different destination) were investigated with potential application in uniforms addressed to firefighters. Studied materials were constructed with the following raw materials: Kevlar, Nomex, PTFE, PU, and carbon fiber. Different variants of textiles used to protect firefighters against heat and flame were tested for air permeability. First, materials were tested experimentally in specific constant ambient conditions using an air permeability tester. The main goal of this paper was to design 3D models of multilayer textiles to determine the air permeability of real textiles and predict it for clothing made of these materials. For this purpose two 3D models (monofiber model and multifiber model) were designed. The models differed in degree of yarn structure in woven fabrics, whereas nonwoven fabrics (due to their complicated random arrangement of fibers) and membranes were mapped as a porous media of isotropic porosity. The simpler model treated the yarn as monofilament, while in the second, more accurate model the yarn was made of fibers. The main objective of the experiment was to verify the utility of the models and to investigate the impact of a degree of mapping yarn geometry on air permeability. Obtained outcomes of the simulations for both models showed correlation with the experimental results; however, values of calculated air permeability obtained by simulations performed on more precise model were clearly closer to the experimental outcomes and show which parameters of geometric structure of the yarn could be an important factor in the modeling of airflow through the textiles.
