Abstract

The article discusses types of insulating layers used for outerwear, i.e. materials made with natural, synthetic and mixed fibers, their thickness, surface density, suitability for certain temperatures, advantages and disadvantages, as well as their air permeability and heat storage properties of packaging samples. Taking into account the fact that heat-retaining materials prevent the intake of cold from the outer ambience and maintain the thermal balance of the body as well as in view to create a package of outerwear that will meet climatic conditions of Uzbekistan, findings have been reviewed and the study - launched based on the indicators of air permeability and heat saving properties of the insulation package, lining and insulation. As for the air permeability, readings of a cotton insulation bag sample reached the highest point (70.7 dm3 /cm2 s). As per the heat-saving indicators, the highest point was shown by paired (63 %) packaging samples with heating layers. When choosing packaging materials for children’s outerwear, consideration was given to their comfort, lightness, hygroscopicity, hypoallergenicity, wear resistance, compatibility with weather conditions, the issue of recommending packaging materials at account of consumer demand, has been closely studied.
