“…Specifically, a solution containing antibacterial agents is applied to the fabric using coating, immersion, or other processes, and then the fabric is dried. The antibacterial agents are then fixed onto the fabric through adsorption, chemical bonding, or van der Waals forces, giving the fabric a certain degree of antibacterial function (Faheem et al, 2017;Gao et al, 2021). Common post-processing methods include impregnation, surface coating, and graft modification (Vila et al, 2020).…”

With the improvement of living standards, people’s awareness of health and environmental protection continues to strengthen. The production of textiles with antibacterial functions is one of the effective ways to protect people from or reduce bacterial invasion. Therefore, textiles with antibacterial functions are increasingly favored by people. At the same time, due to the impact of global warming, people are committed to reducing carbon emissions in all aspects of life. The biodegradable material polypropylidene carbonate (PPC) that can consume carbon dioxide (CO2) in the production process fully conforms to people’s environmental protection concept. However, polypropylidene carbonate itself has poor thermal stability and narrow application range. Polypropylidene carbonate thermoplastic polyurethane (PPC-TPU) is obtained by chain extension modification, which can broaden the application range of polypropylidene carbonate. To develop a yarn with excellent antibacterial and mechanical properties, which can be woven into fabrics for medical applications while taking into account environmental protection and degradability, the antibacterial yarn in this article was prepared by electrospinning using PPC-TPU and polylactic acid (PLA) yarn as raw materials. The preparation process was optimized by adjusting the supply speed, winding collection speed and horn barrel speed, and the optimal concentration of antimicrobial agent was explored by adding different concentrations of benzalkonium bromide antimicrobial. Through the characterization of the properties of the materials, we believe that PPC-PLA yarn with the addition of 5% benzalkonium bromide has broad development prospects in the medical field due to its excellent mechanical and antibacterial properties.

“…Therefore, the low T m sheath polyester is a key component in the manufacture of nonwovens, endowing nonwovens with excellent mechanical properties and flexibility. 4,5 Commercial low melting temperature polyesters are mostly copolyesters based on PBT and poly(tetramethylene oxide) (PTMO), 6 such as Hytrel, a copolyester developed and commercialized by DuPont, 7−9 Arnitel commercialized by DSM, 10 and Pelprene developed by Toyobo. 11 In these copolyesters, PBT as a hard segment in the polymer chain forms crystalline domains, 12 which enables good mechanical properties and endows the thermally bonded nonwoven with excellent resilience.…”

Sustainable low melting temperature bicomponent polyester fibers that can be circularly recycled were developed. The potentially biobased poly(hexamethylene terephthalate) (PHT), acting as the low melting temperature sheath material in the designed bicomponent fibers, was synthesized in a pilot scale. The obtained PHT with an intrinsic viscosity of 0.47 dL/g showed suitable processability when it was processed together with a poly(butylene terephthalate) (PBT) core in a melt-spinning process of bicomponent fibers. Compared with the commercial low melting temperature terephthalate−isophthalate copolyester LMP-160, PHT showed superior mechanical properties according to DMA analysis. The low melting temperature bicomponent fibers with a ratio of the PBT core and PHT sheath at 70:30 were produced smoothly at 290 °C in a pilot melt-spinning line. Preliminary chemical recycling investigations by methanolysis revealed that PHT/PBT bicomponent fibers were completely depolymerized within 2 h at 200 °C, yielding pure terephthalate, which could be conveniently separated and recycled. This indicated the feasibility of circular recycling, which will greatly improve the sustainability of nonwovens thermally bonded by these new bicomponent fibers.

“…To modify these fibers, several nanomaterials have been synthesized. The nanomaterials coated fibers overcome the drawbacks of synthetic and natural fibers including wrinkle-resistant, 5 fire-resistant, 6 and others. The graphene oxide nanosheets modified with titanium dioxide (TiO 2 ) nanoparticles and further coated on the cotton fabrics provide self-cleaning properties, ultraviolet (UV) protection, and enhances electrical conductivity.…”

Fibers are the unit component for product development. They can be divided into two types: synthetic and natural fibers. Recently, emerging nanotechnology has played a vital role in advancing next-generation fabrics. The nanomaterials provide several unique properties such as higher conductivity, self-cleaning, water-resistant, and others. Owing to their advanced properties, the fabrics are being developed by coating and integrating with nanomaterials. Therefore, in the presented work two cotton samples were modified with titanium dioxide (TiO2) and zinc oxide (ZnO). These samples were further examined under various techniques including scanning electron microscopy (SEM), UV-visible spectroscopy, X-ray fluorescence (XRF), and Fourier-transform infrared spectroscopy (FTIR). Furthermore, these samples were evaluated at varying wavelengths with UV light and the obtained results demonstrated that the nano-coated fiber samples can be differentiated at 365 nm.
