a scouring process which uses sodium hydroxide to remove non-cellulosic impurities—including hemicelluloses, mineral salts, pectin and wax—from cotton. The process yields a fabric which possesses a high and even wettability so that it can be bleached and dyed uniformly.
a unit of force used to measure the strength of a textile yarn (see tenacity).
a measure of viscosity, equal to 0.001 newton second per m2.
Centrifugal casting (composites):
in this process the reinforcing fibres and the resin are introduced into a rotating cylindrical metal mould and the speed of rotation gradually increased. The resin impregnates the reinforcement under the influence of the centrifugal
a fabric coated with vulcanised rubber which is wrapped around the bead section of a tyre before vulcanisation of the complete tyre. Its purpose is to maintain an abrasion-resistant layer of rubber in contact with the wheel on which the tyre is mounted.
