Five series of control and Biodegradable gloves were prepared. Each series were buried in a
separate compost soil with pH around 4-6. The temperature of decomposition environment was
controlled at 29 – 30
o
C with relative humidity of 80%. The soil moisture was maintained at 80 %.
Each series was taken out weekly for further testing. The tensile test was carried out according to
ASTM D412. The gloves were cut into dumbbell shapes before being subjected to the tensile test.
The crosshead speed for the Instron tensile machine was set at 500 mm/min. Tensile strength of
NRL films, elongation at break, and modulus at 100, 300, and 500 % elongations were taken. The
tear strength test was carried out according to ASTM D624 by using Instron ™ machine. The
gloves were cut into crescent shapes and thickness of the sample was measured before testing. The
crosshead speed was set at 500 mm/min. All the results obtained were based on average of five
samples.
