Sorption of moisture by resorbable surgical sutures in a wide temperature range

Methods are proposed for calculating the equilibrium moisture content and finding the sorption isotherms of resorbable sutures made from polyglycolic acid and polydioxanone based on their chemical structure, which allow modeling and optimizing the conditions for drying them. The calculations were performed with a thermal sorption equation and the Van Krevelen method. The calculated sorption isotherms were confirmed experimentally. The constants of the thermal sorption equation obtained and the proposed method of estimating the thermal sorption coefficient allowed theoretically calculating the sorption values in a wide temperature range and the heat consumption for the drying process.[PUBLICATION ABSTRACT]
