22s GRAY WARP YARN (SKEIN) 
One of the chief requisites of warp yarn is strength. This property 
is highly desirable because the yarn during weaving must withstand 
high tension as well as chafing. Strength is also important in respect 
to the wearing qualities of the cloth. 
Examples of the strength data for 22s gray warp yarn spun from 
grade No. 5 eastern and western cottons are given in Tables 6 and 7, 
respectively. The break per 22s is found by multiplying the average 
strength by the average size and dividing by the specified number — 
22 in this case. As an illustration, refer to columns under 19.9 turns, 
Table 6. The 89.67 pounds (average strength) multiplied by 21.20 
(average size) divided by 22 (specified number) equals 86.41 (break 
per 22s). Similarly, other strengths per 22s were determined.
