“…In this study, the samples are circular in shape and the deformation head probe is the same as the one used for the mechanical tests previously described (Figure 3a). More information on this tensile test is presented in [6,17]. This analysis evaluates whether the behaviour of the elastomeric sample is always within its elastic range during MD.…”

Research has proven that mechanical deformations (MD) caused by hand flexing affect the structure of disposable protective gloves. However, these studies do not consider the presence of a physiological solution such as sweat. The combination of mechanical constraints and sweat might modify the mechanical and physical properties of the protective gloves and therefor their effectiveness. The main objective of this work is to evaluate the combined effects of human sweat and MDs on certain physical and mechanical phenomena that could affect the structure of nitrile rubber protective gloves. The strain energy, crystallinity, swelling and glove surface profile were investigated. Combined with MDs, the physiological solution significantly affects the structure of the gloves. Contact of the glove sample with the physiological solution modified the strain energy and induced a swelling that modified mechanical properties. Also, the deformation frequency greatly affected the strain energy and the number of deformations changed the degree of crystallinity. A qualitative analysis by SEM showed the deterioration of the surface of the gloves in contact with skin. Based on these results, further investigation is needed on the overall effect of sweat on the effectiveness of protective gloves against mechanical and chemical hazards.

“…NBR has nonlinear, rate-dependent mechanical properties. These properties of NBR have been extensively studied in literature, 10,11,[16][17][18][19] but mechanical and physicochemical properties of NBRcoated cotton gloves are still an open question. The coating layer of gloves is formed by vulcanization, with the addition of sulfur, accelerators, and activators to the NBR.…”

In this study, the effect of polyurethane (PU) and carnauba wax (CW) on the mechanical and physicochemical properties of acrylonitrile butadiene nitrile rubber coating gloves was investigated. Thermal decomposition and morphological characterizations were carried out using Thermogravimetric analysis (TGA) and Scanning Electron Microscopy (SEM), respectively. Fourier-transform infrared spectroscopy (FTIR) analysis was done to determine the chemical interactions between NBR and PU in the polymer matrix. After the vulcanization of NBR, including PU and CW, thermal stability was increased. The spectrums of FTIR showed that carboxyl groups of NBR were linked to the PU to form stable complexes between polymeric chains via H-bonding. SEM images showed that because CW acted as a dispersant for the colloidal particles, the surface appeared smooth compared with the non-containing PU/CW samples. Tensile and tear strength and abrasion resistance tests were conducted using the specimens of vulcanized NBR including PU/CW under uniaxial loading. Test specimens were prepared using hydraulic mold according to EN 388 standards. Cross-head speeds were chosen as 100 mm min À1. The chemical and morphological changes due to PU/CW had no significant effects on the macromechanical responses of the tensile and tear strength. However, it was obviously determined that the abrasion resistance was enhanced by the increase in the amount of CW.

“…This situation is especially relevant to protective gloves. Vinches et al exposed nitrile glove samples to nTiO2 solution in water with dynamic deformations simulating flexing [16,17]. ICP-MS analyses of sampling solutions suggest the penetration of the nitrile gloves when they were subjected to dynamic mechanical deformations for periods of 5 hours or more.…”
