From these bobbins the silk is reeled into hanks of definite length for the market.
The English cotton yarn and spun silk counts are reckoned upon the number of hanks of 840 yds.
Thus 2/40 9 cotton indicates single 40 9 doubled to 20 hanks by 840 yds.
To the lb., while 40/2 fold spun silk means a single 80 9 doubled to give 40 hanks of 840 yds.
This solution is maintained at a heat of 195°, and in it the hanks of raw silk are immersed, hung on a wooden rod, the hanks being continually turned round so as to expose all portions equally to the solvent influence of the hot solution.
