Influence of moisture content of natural boiled silk on the physical and mechanical properties of threads

AbstractThe paper studies the influence of moisture content of natural boiled silk on the physical and mechanical properties of the threads. It was found that at 30% humidity, the strength of threads with a linear density of 3.23 tax x 4 and 4.65 tax x 3 increases by 10%, elongation by 13% and endurance by 60%. At 40% humidity, the strength of the boiled dyed silk thread decreases, the elongation increases. The maximum strength gain is achieved at a humidity of 16%. It should be noted that most of the research works are devoted to the study of the effect of elevated temperatures on the threads with the following determination of breaking loads and elongations in humidity and atmospheric conditions. The sample taken for testing and kept under certain humidity conditions was placed in the box, weighed and dried.
