Doubling

Doubling
DOUBLING
The twisting together of two or more threads to make a stronger or fancier thread. The operation consists in drawing threads from two or more cops or bobbins and twisting them together with the required number of turns per inch. This amount of twist varies considerably according to the purpose for which the yarn is required. Fewer turns are given to yarns for mercerising and hosiery, but yarns for sewing cotton or making healds require a great amount, 2/100's for instance, varies from 15 to 40 turns per inch. Many crepe yarns have 60 or more turns per inch. Doubled yarns possess greater strength and elasticity than a single yarn of the same weight (see Cop and Cop Doubled Yarns)
