This study focuses on two different kinds of cork leathers that are environment friendly and represent as an important sustainable alternative to leather. The general properties of cork leather have been investigated in this study to highlight their potential use as coated-textile structures. The potential use of cork fabrics as technical textiles is also discussed to promote the use of technical textiles, such as buildtech and automotive textiles. The sound absorption and thermal properties of the cork structures are tested and compared with those of reference lamb leather. It is found that the developed cork-based structures have promising mechanical, thermal, and sound absorption properties for further application. [ABSTRACT FROM AUTHOR]

Polylactic acid (PLA) polymer and wool oil (lanolin) have been used to develop nanostructures for wound dressing management. Lanolin has been extracted from raw wool surfaces and used as a by-product in wide range of pharmaceutical areas. Different solutions with varying concentration of the PLA/lanolin and sodium alginate/lanolin solutions have been prepared and then nanostructures are developed using electrospinning method. The developed structures are aimed to use as smart wound dressings. During the production stage, the parameters of the electrospinning process have been changed to develop the optimum structures. The effect of solution concentrations on the applied voltage and the distance between the pipette tip and the collector is highlighted. The spinnability of lanolin is the main objectives of this study and the PLA/lanolin nanostructures are designed and manufactured successfully. The essential test methods have been performed to measure the usability of the produced materials as wound dressings. These are liquid absorption capacity, horizontal/vertical wicking, SEM, degradation, pH, antibacterial assay, and tensile properties. From the tested parameters, it is obviously found that the use of PLA/lanolin as wound dressing is suitable according to initial in vitro test results. [ABSTRACT FROM AUTHOR]
