Sažetak
The aim of this research was to investigate the influence of yarn structure on biodegradability. Soil burial tests, under real conditions, for a period of 25, 50 and 100 days, were used to observe the biodegradability, evaluated by analysing yarns’ fineness and tensile properties. Two types of yarns, composed of 60% Modacrylic, 38% Cotton and 2% Polyamide, and the same fineness of 30 tex were tested, with only difference in yarn structure (sample A represents a single, while sample B plied yarn). By increasing the burial time period, the yarn fineness increase ; i.e. yarn count decreases by 33% for single and 30% for plied yarns. A more significant difference between the tested yarns is evident in the decrease of breaking forces, where after 100 days, the decrease is twice as great for single yarns (31%) than for plied yarns (14%). Consequently, the breaking elongation is greatly increased and amounts to 252% for single and 211% for plied yarns. The greatest increase was recorded in the period of the first 25 days with amounts of 133% for single and 126% for plied yarns. In the following periods, the elongation decreases linearly. This research demonstrates the importance of yarn structure by emphasizing the differences in the degradation process. The increase in fineness, a two-fold decrease in force, and an increase in elongation, indicate that the degradation process is more pronounced in single than in plied yarns. By plying two single yarns, the structure is strengthened and the degradation process is slowed down.
