Blending of plastics used in packaging is an interesting approach for recycling or upcycling. Therefore, this study focused on the effects of processing on the properties of recycled PP and PP/LDPE blends. MFI measurements, Differential Scanning Calorimetry (DSC) and hot-stage polarized optical microscopy techniques were used to investigate the miscibility of PP/LDPE blends based on the thermal properties, degree of crystallinity, crystallization and morphology development in the blends. The MFI indicates, that PP and PP/LDPE blends are marginally sensitive to degradation at common processing conditions. The degree of crystallinity of the blends decreases with an increase of the LDPE content. Furthermore, the spherulite growth rate and crystal size of PP decrease with an increase of LDPE content. The shifts of crystallization temperatures from the DSC measurement, in conjunction with the crystallization kinetics, indicate that PP/LDPE (25 wt% LDPE) is partially miscible.

In this study, novel nylon/spandex elastomeric burn pressure garments were developed with a durable antimicrobial performance using silane and quaternary ammonium compounds (QAC's). A series of physical, mechanical and thermophysiological properties were tested before and after the application of the antimicrobial finish, including air permeability, stiffness, drapeability, bursting strength and extensibility, thermal resistance (Rct) and thermal insulation (in clo units). Antimicrobial tests were performed after 50 washing cycles using AATCC 100 Test Method, and they showed a 99% reduction in bacterial activity for those fabrics treated with the QAC-Silane antimicrobial agents. Physical, mechanical and thermophysiological properties were tested after antimicrobial treatments. A small significant increase was observed in terms of thermal resistance (Rct) (Tog) and isolation (It) (clo) properties for treated fabrics samples. The air permeability, bursting strength and drapeability showed a small significant decrease after antimicrobial finishing, while the elastomeric fabric showed a small but significant increase for fabric stiffness. These results confirm that when these novel pressure garments are used by burn patients, they will not only decrease the incidence of infection but will also provide comfort during prolonged use.
