Outline
To explore the influencing factors and action mechanisms of the tensile properties of rubber gloves, and provide a scientific basis for their design, production, and use.
Rubber glove samples from the same batch produced in June 2023 within the expiration date were selected. After cutting and conditioning, defective products were removed. According to the ISO 37 standard, type 2 dumbbell - shaped specimens were used. Multiple devices were employed, and methods such as contact extensometers and manual non - contact measurement were adopted. Three inspectors conducted independent tests, and one inspector carried out equipment comparison. Additionally, loose - clamping and pre - tension - clamping tests were performed with reference to relevant standards. Statistical analysis was conducted using
The initial test length error will lead to a deviation in elongation at break, such as a 2mm error resulting in an 11% deviation. The results of the holding method were higher than those of the manual method (P<0.05). The deviation of test data of different equipment was less than 5% (P>0.05). The 0.15N pretension can reduce the error, and the elongation at break is low when the loose clamping is 0.5N.
Factors such as the initial test length, measurement methods, equipment, and pre - tension significantly affect the tensile properties of rubber gloves. These factors need to be strictly controlled during production and inspection.
