Influence of Sequential Liquid Ammonia and Caustic Mercerization Pre-Treatment on Dyeing Performance of Knit Cotton Fabric

A two-stage sequential pretreatment including caustic mercerization (CM) and liquid ammonia (LA) treatment was applied to investigate the influence on dyeing performance and handle of knit cotton fabric, and the relationship between dye size and dyeing properties. Various techniques were applied to characterize all the treated fabrics. X-ray diffraction (XRD) and Fourier-transform infrared (FTIR) analyses… Continue reading Influence of Sequential Liquid Ammonia and Caustic Mercerization Pre-Treatment on Dyeing Performance of Knit Cotton Fabric

Biofouling Mitigation Using Graphene Oxide Functionalized Polyethylenimine/Sulfonated Polysulfone Composite Membranes

Biofouling is a major concern in membrane filtration which could adversely have an effect on the overall membrane performance. To address this issue herein, we prepared polyethylenimine-grafted graphene oxide (GO-PEI) as a filler material to be used in the sulfonated polysulfone membrane (SPES). The PEI grafting on GO and successful sulfonation of PES was confirmed… Continue reading Biofouling Mitigation Using Graphene Oxide Functionalized Polyethylenimine/Sulfonated Polysulfone Composite Membranes
