Summary: A neodymium-doped titanium dioxide film was coated on polypropylene nonwoven fabric to prepare multifunctional textiles with antibacterial and ultraviolet protective properties. The antibacterial performance was improved in samples with multiple layers of film coatings, while ultraviolet irradiation enhanced hydrophilicity and catalytic antibacterial ability. Samples with higher ultraviolet absorption had better ultraviolet protective factors and improved antibacterial performance. The morphology and luster of the samples remained unchanged with the addition of neodymium-doped titanium dioxide film, allowing for further applications in antibacterial-coated polypropylene non-woven fabric.

Summary: During the COVID-19 pandemic, the antimicrobial functionalization of textile structures with copper and its compounds has significantly increased. This study applied magnetron sputtering with copper to modify viscose needle-punched nonwoven fabric, which showed strong antimicrobial activity against Gram-positive Staphylococcus aureus and Gram-negative Klebsiella pneumoniae. However, it exhibited weak activity against herpes simplex virus type 1 (HSV-1) in the presence of other viruses.

Summary: This study focuses on improving the fire safety of nonwoven polypropylene fabric by increasing its surface polarity with a surfactant and a conventional finishing method. The treated fabric exhibits higher hydrophilicity and improved flammability properties. The treated fabric also shows higher thermal stability and more char residue at high temperatures. Scanning electron microscopy observations reveal that the treated fabric forms a continuous char structure that effectively isolates the underlying material from fire and oxygen.

Summary: This study investigates the effect of adding alcohols on the grafting of glycidyl methacrylate (GMA) in emulsion graft polymerization. By adding hydrophobic alcohols to the GMA monomer emulsion, the polymerization rate at low monomer concentrations is increased and the foamability of the emulsion is reduced. This novel graft polymerization method has wide industrial application potential and improves the existing issues of conventional emulsion graft polymerization.

Summary: This study developed highly effective leukoreduction filters by using dielectric barrier discharge (DBD) plasma on polypropylene (PP) nonwoven coated with zwitterionic sulfobetaine methacrylate (SBMA) monomer. The modified surface did not affect the material's structural characteristics, but greatly changed its surface chemistry. The optimized grafted membrane showed excellent performance in removing leukocytes, outperforming commercial alternatives while maintaining high erythrocyte recovery.

Summary: Zinc oxide (ZnO) nanorods were successfully grown on the surface of polypropylene (PP) nonwoven fabric (NWF) using the low-temperature hydrothermal method, showing excellent UV protection and antibacterial activity. The ZnO nanorods effectively inhibit photodegradation and significantly enhance the strength properties of the PP NWF.

Summary: The construction industry depletes large amounts of nonrenewable resources and generates millions of tons of mineral waste and carbon dioxide annually. Research and promotion of the use of recycled materials are essential for a more sustainable consumption pattern. Investigating textile waste as reinforcement for cement-based matrices shows promise in enhancing ductility and cracking control.

Summary: The paper presents a method for modifying commercial viscose nonwoven fabric for agricultural use as a modern mulching material. The modified cellulose nonwovens offer a solution for a biodegradable crop cover, eliminating disposal issues post-harvest. This modified material was used in tunnel cultivation of tomatoes, providing heat-retardant, water-absorbing, antiweed mulching properties along with slow release fertilization benefits.

Summary: A single-layer film of copper and/or copper oxide was deposited on a polypropylene nonwoven fabric substrate to prepare multifunctional textiles with a metallic color appearance. The color lightened as the Cu content decreased and transitioned into CuO, while the UV protection performance decreased with increasing oxygen flow rate and decreasing film thickness. The hydrophobicity increased slightly with the copper oxide film-coated samples, and electrostatic elimination ability decreased due to the conversion of elemental Cu to Cu2O and CuO.

Summary: Chitosan/TiO2 functionalized polypropylene nonwoven fabrics were prepared through crosslinking of chitosan with glutaraldehyde followed by loading of TiO2 nanoparticles. The functionalized material showed super hydrophilicity and excellent visible light induced photocatalytic antibacterial properties due to the synergistic effects of chitosan and TiO2. SEM images demonstrated the even distribution of TiO2 nanoparticles on the surface of the material. Photocatalytic degradation experiments showed higher photocatalytic properties compared to pure polypropylene under visible light, with a methylene blue degradation rate of 96.4% after 90 minutes of light exposure. The antibacterial properties against E. coli and S. aureus were significantly increased, with bacterial reduction percentages of 98.7% and 96.3%, respectively. The functionalized composite material exhibited promising potential in environmentally friendly antibacterial applications.
