Abstract:

The structural changes and mechanical properties of spun-bonded polylactide (PLA) nonwovens resulting from artificial weathering were analyzed in respect to their application in agriculture. The spun-bonded nonwovens were stabilized on a calender at various temperatures ranging from 60 to 110°C. The weathering process was carried out with the use of a Q-SUN weathering chamber under two selected climatic conditions resembling temperate and subtropical climate, respectively. The artificial aging effect on the nonwovens was assessed by measuring their physical parameters and mechanical properties as well as by analyzing their structural changes by means of Fourier infrared spectrophotometry (FTIR), polarization-interference microscopy (PIM) and wide angle X-ray scattering (WAXS).
