Determination of reliability indicators of thread connections of textile bands for manufacturing of modular system

Abstract

Analysis of the range of existing types of military equipment proved the relevance of using modular systems for the purpose of placing and adjusting them on mobile equipment. Reasonable choice of textile bands with high indicators of strength and types of seams for their connection is appropriate. It has been established that belt bands and thread connections during their operation are negatively affected by stretching, contamination, multiple bending, abrasion, tearing, ripping, the effect of light and weather, moisture, etc., as a result of which the values of their quality indicators gradually decrease. Improvement of modular systems is carried out by using modern bands and appropriate types of seams made of multifilament threads. Based on the analysis of the assortment of modern textile wear-resistant bands presented on the market of Ukraine, samples of polyester and polyamide fibers were selected for further research. In accordance with the operating conditions, significant physical loads affect textile bands when they are caught during movement by objects in the surrounding environment
