Дослідження матеріалів для захисту людини від шкідливих чинників навколишнього середовища. RESEARCH OF MATERIALS TO PROTECT HUMAN FROM HARMFULL ENVIRONMENTAL INFLUENCES

Abstract
The paper is devoting to researching of properties of materials for protection of the person from harmful factors. The issue of protecting people from the influence of external harmful factors to date is very relevant. There are a number of factors, constitutes a threat to the human health in the process of life. The nature of the dangerous influence on the person of external factors is quite diverse by nature of origin, the nature of interaction with the organism and the consequences that cause the action of harmful factors. For protect against the influence of dangerous harmful factors, personal protective equipment is used, the leading place among which is the special protective clothing. When designing protective clothing, important to investigate the properties of materials, as well as the impact of the processes of clothing use on the properties of these materials. The analysis of harmful factors and the study of general properties of protective materials was carried out by analytical and observation methods. Investigation of the influence of operation factors on the change of the properties of textile materials for protective clothing was carried out by experimental method (for the experiment, a tear-off machine of the brand RT-250 was used). The scientific novelty determined by the influences of the washing process on the values of bursting and elongation during the rupture of materials for the manufacture of protective clothing (fabric CORDURA NIR and CORDURA MK, jersey Cool- Max). Based on the results of the study, the authors conclude that the wet processing improves the bursting characteristics of the materials being studied. At the same time, the authors emphasize the need for a comprehensive study of the quality indicators of the materials in question in order to fully determine their protective properties. In the conclusions, the authors suggest the use of investigated fabrics for the manufacture of protective clothing for protection against mechanical damage, and also indicate that the jersey under study does not lose the strength characteristics during washing. Research materials can be used to improve the design of clothing protective special.
