    (2018) Дячок, Т.М.; Diachok, T.M.; Березенко, С.М.; Bereznenko, S.M.; Бакал, В.П.; Bakal, V.P.; Александров, М.Є.; Aleksandrov, M.Ye.
    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.

    Проектування жилетів для службових собак. DESIGN OF VESTS FOR GUARD DOGS
    (2018) Будзинський, М.П.; Budzynskii, M.P.; Бакал, В.П.; Bakal, V.P.; Алексанров, М.Є.; Aleksandrov, M.Y.
    The article is devoted to the design of vests for service dogs. Vests for dogs of various designs are widely used by private owners of dogs, and special services, in particular, the cynological units of the police. At the same time, the working conditions of service dogs ànd ordinary dogs are different. There is a need for designing vests, the design of which would meet the purpose and conditions of use of service dogs. However, today the subject of most popular and scientific sources is devoted to designing clothes for dogs, without taking into account the specifics of their use and the typical dimensional features of breeds of service dogs. In this article, the authors determine the initial requirements for the design of vests for service dogs, consider the design features of existing vests, lead to a system of their sizes. The study of the initial requirements for the design of vests was carried out by an analytical method and a method of observation. When determining the main sizes of service dogs of different breeds, an instrumental method was used (measurements were made using a centimeter tape 2000 mm). The structural features of the vests and the basic sizes of the vests are determined by means of analysis and comparison methods, and also by the instrumental method. The experimental sample of the vest for service dogs is made using modern sewing equipment. Dynamic compliance of the sample is determined by method of modeling the situation. Scientific novelty consists in certain basic dimensional features for the design of vests for service dogs, as well as in determining the dependence of the size of vests on the breed, age and sex of the dog. Based on the conducted experiments (measurements of dogs of service breeds), the authors conclude that it is inexpedient to design a universal waistcoat of uniform size and emphasize the need to design waistcoats in different sizes. The practical significance of the study is the development of an experimental vest sample for service dogs. The conclusions contain the initial requirements for the design of vests for service dogs, determined by the authors. The materials of the article can be used to improve the process of designing clothes for official dogs of cynological units of the National Police of Ukraine.
