Purpose: Study explored the effects of ageing, induced through artificial weathering, on the physical, mechanical, and structural properties of polypropylene nonwovens produced using the spun-bonded technique and modified with iron stearate as a photodegradant. Design/methodology/approach: Key parameters such as mass per unit area, apparent density, air permeability, tensile strength, chemical structure, and crystallinity index were analysed to evaluate the matematerials’behaviour during ageing and assess their potential as agrotextiles. Findings: The results revealed that initial ageing stages led to partial structural reorganisation, manifested by increased crystallinity and improved mechanical properties. However, extended ageing caused significant deterioration in these properties due to progressive structural degradation. Reduced crystallinity, decreased tensile strength, lower apparent density, and increased air permeability are correlated with the crystalline phase and the breakdown of polymer structures. Research limitations/implications: Despite the degradation, PP nonwovens demonstrated properties that are favourable for agricultural applications. Their high initial tensile strength and structural stability make them effective for soil protection, moisture retention, and weed suppression. Practical implications: The gradual degradation under environmental conditions offers an advantage by eliminating the need for manual removal at the end of the season, facilitating microbial breakdown, and reducing long-term environmental impact. Originality/value: Analysis allowed for the behaviour assessment during ageing and for concluding their durability and potential application. PP-based nonwovens modified with photodegradants balance functional durability and environmental friendliness. However, optimising their composition and properties to meet specific requirements is essential to ensure effective performance and sustainable biodegradation after use.
