The yarns are chiefly used by manufacturers of powder bags.
The metric system of weights and measures has been adopted so widely that it forms the most suitable basis for the titrage or counts of yarns.
The yarn is now ready for reeling into skeins or for warping, both of which operations are common to all the textile yarns.
Spinning mills are established, however, in most of the large Lancashire towns as well as in some parts of Cheshire and in Yorkshire, where there is a considerable industry in doubling yarns.
A great amount of doubled and trebled yarn is now sold, though it does not appear that recent expansions have added much to doubling spindles, and considerable developments continue in the use of dyed and mercerized yarns.
