The Federal trade commission’s definition for nylon fibre – “A manufactured fibre in which the fibre forming substance is long-chain synthetic polyamide in which less than 85% of the amide linkages are attached directly (-CO-NH-) to two aliphatic groups.” In September 1931, American chemist Wallace Carothers reported on research carried out in the laboratories of the Dopant[…]
Measurement of Crease Recovery Crease recovery is measured quantitatively in terms of crease recovery angle. Principle A wrinkle-free rectangular specimen of prescribed dimensions is folded in half and compressed under a load for a specified time. The load is then removed and the specimen is allowed to recover for the specified time. The amount of[…]
Description of Shirley Stiffness Tester The stiffness tester consists of a platform with smooth low friction and flat surfaces such as glossy metal or plastic. The platform is supported by two side pieces made of plastic. Index lines are engraved on these side pieces, inclined at an angle of 41.50 below the platform surface plane.[…]
Principle The pressure in a liquid is exerted in all directions and this phenomenon of a liquid is used for testing bursting strength in hydraulic bursting strength tester. Sample Size The specimen for this test should be cut so that the sample is ½ inch greater in diameter of the clamp ring. Ten specimens are[…]
The lea tester is operating on constant rate of extension (CRE) principle, in particular pendulum type. Description of Lea Tester It is a motor driven, pendulum type lea tester. It consists of an upper jaw and a lower jaw. The lower jaw can be engaged with a screw mechanism, which is driven at a constant[…]
For our daily purposes, we wear different types of dresses. For the morning walk, we like to wear tracksuits. For swimming, we’ve to wear swimsuits. Also for heavy works we need to wear work-wears. So the physical properties of our clothing are an important factor. To have good physical properties, tear and tensile for woven and bursting strength for[…]
