The behaviour of the pile layer of artificial turf is an important element for the performance of artificial turf. As a top layer, it is constantly under deformation, with the most possible being bending . The bending behaviour of monofilaments of linear low density polyethylene (LLDPE) is strongly influenced by the processing parameters, the type of polymer, and geometrical factors, which in combination with each other seem to have a strong influence on the behaviour of the final product. From the results obtained, the use of octene instead of hexene as a monomer yields better results for resilience due to a higher concentration of intrafibrillar tie molecules for the same degree of DSC crystallinity of the LLDPEs. The increase in the final cross section of monofilaments based on the same LLPDPEs resulted in a decrease in the intrafibrillar tie molecules due to a slower cooling after melt extrusion.

Badania dotyczyły obróbki wykańczalniczej jedwabiu naturalnego. Mikrostruktura jedwabiu była badana za pomocą skaningowej mikroroskopii elektronowej, a właściwości mechaniczne testowane były klasyczną zrywarką firmy Instron, podczas gdy strukturę krystaliczną analizowano za pomocą spektroskopii w podczerwieni (FTIR) oraz rozproszenia promieniowania rentgenowskiego. Wyniki pozwoliły wytypować najlepszą w danych warunkach metodę obróbki.
