Medical product contamination is a serious threat to patients’ health. However, designing medical covers thatensure Janus performance and outstanding abrasion resistance, mechanical performances has remained a great challenge. Inthis study, a novel Janus nonwoven fabric nonwoven fabric consists of a hydrophilic inner layer of polylactic acid (PLA)/lowmeltingpolylactic acid (LPLA) and a coated outer layer of hydrophobic thermoplastic polyurethane (TPU) is successfullyfabricated. The subsequent PLA/LPLA-TPU textiles exhibits excellent protective performance of inner absorption. Moreover, the coating improves tensile strength and increases abrasion resistance. A mechanism of mechanical failure isfurther studied. This kind of nonwoven fabric is suggested to be a promising candidate for medical covers and health supplies.

In order to improve the low velocity impact resistance, flexible PU foam composites (FPUC) with a sandwichstructure are proposed. The interlayer is composed of a concave-convex fabric structure while the top/bottom layers are madeof polyurethane foam (PU). The core is prepared as follows. Seven warp knitted spacer fabric types (WKSF) (WKSF.1-7) arelaminated with different number of layers to form cuboids, which are fixed firmly between two layers of low melting pointpolyester (LMPET) fabrics via hot melting. The effects of spacer yarn density, spacer yarn inclination angle, combination ofspacer fabrics, and number of lamination layers on the dynamic cushion performance are evaluated. With the impact energybeing 16 J, FPUs demonstrate an energy absorption level that is 19 % and 39 % greater than PU and WKSF. Furthermore,ultra-high molecular weight polyethylene fabric can effectively enhance the surface strength. Finally, the results arecomputed via theoretical prediction formulae of dynamic buffer resistance is in conformity with the experimental test results.

Drug-resistant pathogens pose significant pressures and challenges for medical protective materials withhighly effective antibacterial/antiviral and rechargeable properties. In this study, a clean, rechargeablephotodynamic antibacterial/antiviral strategy was proposed after nanofibrous membranes were graftedby photosensitive 4,4, -terephthalic di-phthalic anhydride (TDPA) and natural polyphenol chlorogenicacid (CA) antibacterial agent. The resultant membrane released the maximumOH and H2O2 capacitiesof 6188.56 lg/g and 842.00 lg/g, respectively, exhibited the storage antibacterial stability even storedfor 30 days in the dark. After seven quenching, the charging capacity retained more than 70% of the original. The antibacterial efficiency of the membrane showed more than 99%. In addition, the antibacterialefficiency decreased by only 3% after water washing. Moreover, it demonstrated an excellent antiviralproperty whose antiviral activity against H3N2 achieved 3.6 PFU/mL. This daylight-driven rechargeablenanofibrous membrane can be used to develop reusable medical protective materials with rechargeableantibacterial and antiviral efficiency.

Polyethylene terephthalate (PET) nonwoven fabrics, carbon fabrics (CF), and flexible polyurethane (PU) foamsare made into novel sandwich composites using one-step molding. The flame retradance and mechanical properties of thesandwich composites are evaluated, examining the influences of the content of flame retardant agent (20, 30, 40, and 50 wt%)and areal density of PET panels (200, 300, and 400 g/m2). The test results show that the PET/CF/PU sandwich composites arerated flame retardant as V0 and do not generate melts. The failure mode of PET/CF/PU sandwich composites converts fromoverall fracture to layered fracture as a result of increasing the flame retardant agent. The tensile strength at break of PET/CF/PU sandwich composites with corresponding PET panels is 650 N for 200 g/m2, 928 N for 300 g/m2, and 1744 N for 400 g/m2,which are 42.63 %, 60.48 %, and 77.85 % greater than those of the PET/PU sandwich composites. Moreover, the burstingstrength of PET/CF/PU sandwich composites with corresponding PET panels is 3322 N for 200 g/m2, 3869 N for 300 g/m2,and 4978 N for 400 g/m2, which are 195 %, 180 %, and 143 % greater than those of the PET/PU sandwich composites.

In order to deeply explore the fiber characteristics influencing on stab resistance of shear thickening fluid (STF)-impregnated fabrics, two different weaving fabrics, ultra-high molecular weight polyethylene (UHMWPE) fabric and Kevlar fabrics are saturate the various concentrations and particle size of STFs. Result shows that, SiO2/PEG-200 blends demonstrate quick shear-thickening property, and the critical shear rate lowers to 1.2-45 s-1 with higher concentration of 75 nm SiO2. STF concentration and particle size significantly affect spike puncture resistance property, but the knife stab resistance mainly depends on fiber characteristics. Comparatively, STF-UHMWPE composite fabrics exhibit better knife stab resistance but weaker spike puncture resistance than STF-Kevlar fabrics. This study can provide an optimization for structure design of stab resistance armors in the future.
