To such an indicator the authors refer to the index of vapor permeability, which determines the ability of the material to conduct vaporous moisture through a unit area of the sample for a certain time. In the article the authors note a great variety of existing methods and test equipment used to determine the vapor permeability of materials used for clothing and emphasize the significant difference in the values obtained by different methods. It is also noted that most of the existing methods do not provide close to operational test conditions, so the authors propose as an alternative to use the method of determining the vapor permeability of moisture-protective materials, which allows modeling various operating conditions, and a device for its implementation. The significance of test conditions for interpretation of research results and identification of factors that have a significant impact on the ability of moisture-protective materials to transport water vapor from the space under the clothes to the outside is shown. The authors have revealed dependences of vapor permeability of materials with polyurethane microporous coating and membrane layer on temperature and outdoor air velocity, which allow predicting vapor permeability of moisture-protective materials at air temperature from plus 5\u00b0C to plus 15\u00b0C at outdoor air velocity from 0 to 4 m\/sec. It was revealed that with decreasing ambient air temperature and increasing outdoor air velocity the vapor permeability of moisture-protective materials will increase.<\/p>\n<p style=\"text-align: justify;\"><strong>Keywords:<\/strong> vapor permeability; operating conditions; temperature; outdoor air velocity; moisture-protective materials; overalls; influence<\/p>\n","protected":false},"excerpt":{"rendered":"<p>Ivashko Ekaterina Igorevna Vitebsk State Technological University, Vitebsk, Republic of Belarus E-mail: ivashkokatrinka@mail.ru ORCID: https:\/\/orcid.org\/0000-0002-3124-2104 RSCI: https:\/\/elibrary.ru\/author_profile.asp?id=1098730 SCOPUS: https:\/\/www.scopus.com\/authid\/detail.url?authorId=58567181400 Burkin Alexander Nikolaevich Vitebsk State Technological University, Vitebsk, Republic of Belarus E-mail: a.burkin@tut.by ORCID: https:\/\/orcid.org\/0000-0002-2963-6390 RSCI: https:\/\/elibrary.ru\/author_profile.asp?id=800250 SCOPUS: https:\/\/www.scopus.com\/authid\/detail.url?authorId=57473838700 Abstract.
