“…Chemical hazards have become a part of industrial production and emergency accidents, such as industrial chemical production, chemical spillage accidents, and chemical warfare agents (CWAs). − Functional clothing can help protect people from environmental hazards. − Especially, chemical protective clothing (CPC) is of vital importance to the chemical hazard safety of the chemical personnel involved. − CPC is classified as fully enclosed and selectively permeable according to the protective mechanism. − The former is fabricated with rubber-based composites that can provide excellent protection against chemical hazards in severe environments, while its lost permeability for air and heat causes reduced wear comfort and then affects the working efficiency. , For selectively permeable CPC, its ability to protect human beings from hazardous gas was achieved based on the rejection effect of a porous membrane. − Meanwhile, the permeability of this membrane matrix also offered enough channels for air passage, ensuring good breathability. In addition, considering the comfort in wearing and the working efficiency, emerging fabric-based absorption materials with better air permeability and desired flexibility are also regarded as more prospective choices to fabricate CPC. − …”

Chemical hazard protection safety and wear comfort of chemical protective clothing (CPC) are vital for the chemical personnel involved. Unfortunately, low air permeability and poor durability of adsorbate loading from conventional protective textiles coated with porous substances still cause tremendous threats to health and reduce working efficiency. Herein, to solve these limitations, highly exposed activated carbon (AC) nanoparticles are locked inside the chamber of porous meta-aramid fibers (PMIAs) from physical blending and wet-spinning as well. By controlling the pore parameters of PMIA fibers via adjusting the coagulation conditions (bath temperatures and bath composition) during the nonsolvent phase separation (NIPS) process, not only the inner AC is exposed highly but also the adsorption capability of AC-filled meta-aramid fibers to hazardous gases and corresponding mechanical properties is optimized. The resultant fiber (with 20 wt % AC) demonstrates a high adsorption capacity for benzene (102.26 mg/g), sufficient tensile strength (1.82 cN/dtex), and is recyclable. Finally, the further developed fabric from this composite fiber also offers a higher air permeability (11.4 cm 3 s −1 cm −2 ) and a firmer loading of AC compared to commercial CPC (FFF02). This work should serve as a source of inspiration for improving the comfort and safety of CPC.

“…Understanding the properties of the fibers at the molecular level provides an accurate identification of its material properties. Now, we can design and create fabrics that are exceptionally highly durable and resistant against extreme harsh conditions 1–7 . Thus, applying the chemical and physical knowledge gained in the modern world 8–15 has always helped to understand the nature and composition of the excavated fabrics.…”

The aim of this work is to determine the type of material in the given unknown fabric which was excavated from the various archeological sites in Israel using advanced material technology. The four fabrics that were obtained appeared as fragmentary and very degraded textiles. Therefore, we established the treatment method for these fabrics that would be most suitable to deal with the analysis and identification of the material they are made. Fourier transform infrared spectrometry (FTIR), nuclear magnetic resonance (NMR), energy dispersive x‐ray analysis (EDX), scanning electron microscope (SEM) and differential scanning calorimeter (DSC) analysis were used to confirm the material in the fabric samples. Upon detailed analysis it was concluded that all the fabrics are composed either of the synthetic materials such as nylon 6, polyester, and polyacrylonitrile (PAN). The developed method and analysis present herein has the advantages of being rapid and effective for identification of the fabrics and can be applied to varieties of archeological fabrics.

“…However, the usage of these compounds is constrained since they can create dioxin and other extremely toxic chemicals, while thermally decomposing, making them hazardous to the environment. [ 11,12 ] Many phosphorus‐containing compounds have flame retardant properties when incorporated in relatively low concentrations into epoxy resins. When burning, phosphorus‐containing flame retardants do not produce highly harmful gases.…”

The preparation of a novel polyphosphonate (PSFR) is described here, starting from phenylphosphonic dichloride and an equimolecular mixture containing equal amounts of two bisphenols, namely 4,4 0 -dihydroxydiphenyl sulfone and 2-(6-oxido-6H-dibenzo<1,2>oxaphosphorin-6-yl)-1,4-benzenediol, following the polycondensation reaction in solution. Then, new environmentalfriendly nanocomposites having improved flame retardancy have been prepared by incorporating PSFR and halloysite nanotubes (HNTs) into epoxy resin. The effect of PSFR and HNTs contents on the chemical and physical characteristics of epoxy nanocomposites was investigated. The success of the reactions was monitored by infrared spectroscopy (FTIR) while microscopic related techniques (SEM) gave information on the morphology of the products. The thermosets exhibit glass transition temperatures in the range of 62.4-97.1 C and thermal decomposition temperatures in the interval of 296-359 C. The appearance of the char residues obtained by pyrolysis was studied by SEM measurements. The flammability behavior has been studied by microscale combustion calorimetry (MCC) tests. A considerable improvement in the flame retardancy of the thermosets was obtained by simultaneous incorporation of HNTs (10 wt%) and PSFR (equivalent of 1 wt% P) into epoxy resin.
