“…Widely used worldwide fleece garments are among the best representative products commercially available from recycled PET. The preparation of fibers from recycled PET to fabricate trendy fleece garments, such as sweaters and jackets, is one of the best examples of proper waste management based on upcycling [ 14 ]. The PET waste is melted and re-extruded to realize pellets or filaments and is re-worked into fabric manufacturing processes.…”

Wasted synthetic fabrics are a type of textile waste source; the reuse of them brings environmental protection and turns waste into a valuable material. In this work, the used nylon (polyamide) stockings were transmuted into a fine fibrous membrane via an electrospinning process. In addition, the safety antibacterial agent, monoacylglycerol (MAG), was incorporated into a recycled fibrous membrane. The results revealed that the neat, recycled polyamide (rPA) fibers with a hydrophobic surface could be converted into hydrophilic fibers by blending various amounts of MAG with rPA solution prior to electrospinning. The filtration efficiency and air/water vapor permeability of the two types of produced membranes, neat rPA, and rPA/MAG, were tested. Their filtration efficiency (E100) was more than 92% and 96%, respectively. The membranes were classified according to Standard EN1822, and therefore, the membranes rPA and rPA/MAG were assigned to the classes E10 and E11, respectively. The air permeability was not affected by the addition of MAG, and water vapor permeability was slightly enhanced. Based on the obtained data, prepared rPA/MAG fibrous membranes can be evaluated as antifouling against both tested bacterial strains and antimicrobial against S. aureus.

“…The electrospinning technique usually involves a high voltage power supply, a collector for the collection of the nanofiber, and a spinneret for the extrusion of polymeric solution. Nanofibers of very fine diameters can be produced through this technique [11]. Polymeric electrospun nanofibrous membranes are widely used for biomedical and antibacterial applications [12].…”

Persistent wounds are the most problematic for the patient as well as for the health system. Skin wounds are most exposed to bacterial attacks, which not only caused wound infections but also slow the healing process. There is a dire need to develop a better wound dressing or scaffold material that can increase the wound healing process. This study involves the development of electrospun nanofibers based on Silvadur loaded polyacrylonitrile membranes. Samples were developed by using five different concentrations (2 wt%, 4 wt%, 6 wt%, 8 wt%, and 10 wt%) of Silvadur loaded in PAN solution. The developed polymeric electrospun nanofibrous membranes possess a smooth surface with an average diameter lies in the range of 152.94nm to 185.05nm. Furthermore, these fibers show excellent antibacterial activity up to 92.25% in the case of Gram-negative (Escherichia Coli) bacteria and 98.52% in the case of gram-positive

“…PPF has the characteristics of high strength, high impact resistance, and wear resistance, which are widely applied for producing polypropylene plastic bag and injection molding products [17][18][19][20][21]. Its traditional disposal methods for abandoned polypropylene waste are incineration or landfills, which pose serious risks to ecological balance and people's health [22][23][24].…”

Compressive Behavior, Microstructural Properties, and Freeze–Thaw Behavior of Tailing Recycled Aggregate Concrete with Waste Polypropylene Fiber Addition

To improve the high brittleness of recycled aggregate concrete containing iron ore tailings (TRAC), the feasibility of adding polypropylene fiber (PPF) to TRAC was studied by performing a compression stress–strain curve test, scanning electron microscope characterization, and a freeze–thaw cycle test. The results indicated that PPF had a beneficial impact on reducing the brittleness of TRAC. With the increase in PPF content, the peak strain increased, the elastic modulus decreased, and the peak stress and energy absorption capacity increased at first and then decreased. Furthermore, the microstructure investigation revealed that the interface friction between the PPF, aggregate, and cement matrix was the main source of energy dissipation. When the load acted on the concrete, the stress was dispersed to the fiber monofilaments, thus effectively enhancing the peak stress and peak strain of concrete and suppressing the generation and development of cracks in the concrete. In terms of freeze–thaw resistance, adding a small amount of PPF could reduce the negative effects of the freeze–thaw process on the cement matrix. On the premise of ensuring strength, the waste utilization should be as high as possible. Therefore, it was suggested that the content of PPF in fiber-reinforced tailings recycled aggregate concrete (TRAC-PP) should be 0.6%.
