DEVELOPMENT OF THE MODIFIED TENT USB-56

Abstract

The  purpose  of  the  tent  modification  type  USB-56  is  improvements  its  exploitative characteristics and reduction the cost of its production. Method. During the study of the physical and mechanical properties of the fabric, techniques were used to determine linear dimensions, linear and surface densities, to determine the breaking characteristics during stretching of the fabric, to determine the hygroscopic and water repellent properties of the tissue. All of  the  previously  used  methods  are  from  the  normative  and  technical  documentations.  The  selection  of samples of tissue was carried out in accordance with the requirements of normative documents.  Tests  of  fabric  samples  of  cotton  were  conducted  in  the  accredited  analytical  and experimental testing laboratory of Kyiv National University of Technology and Design. The results of the tests  showed  that  according  to  physical  and  mechanical  parameters,  modified  fabric  corresponds  to  the requirements of normative documentations, and according to some indicators exceeds them. However, the results  of  the  tests  after  irradiation  in  laboratory  conditions  using  the  xenon  arc  lamp  showed  that, depending on the exposure area in the natural environment, the aging resistance decreased. Scientific novelty. On the basis of the results of experimental studies of the properties of modified tissue of art. 16sKVgl + VO proved the expediency of its use for the manufacture of tents type USB-56. The dependence of the coefficient of loss of water resistance of the fabric on the region of use of the fabric is determined. Practical value. Recommendations for enhancing the operational properties of the USB-56 tent will form the basis for the development of regulatory documentation for the tent.
