Doubling (Dry And Wet)

Doubling (Dry And Wet)
DOUBLING (Dry and Wet).
Dry doubling is carried on for yarn that is required oozy after twisting, such as for hosiery, also if to be bleached or dyed. This system leaves the thread in an open condition. Wet doubling produces a smooth and clean yarn and the liquid used causes the fibres to adhere to the body of the thread, while the twisting process also binds them together to give a more solid structure and increases the strength. Water only is used for counts up to about 2/60's, but for the finer counts it is usual to add a soap or special solution.
