Warping:
Warping is defined as the parallel winding of yarn from cone or cheese package on to a warp beam. The operation of winding warp yarns onto a beam usually in preparation for slashing, weaving, or warp knitting. Also called warping.
1. Count Of warp yarn,

Total length of yarn in hanks
= …………………………………………………
Weight in lbs

Or,

Length of warp in hanks × number of ends
= …………………………………………………………………
Weight in lbs

Or,

Length of warp in yds × number of ends
= ………………………………………………………
Weight in lbs × 840

Example :
Calculate the count of yarn on a back beam which weights 303 lbs. and has 12000 yards of warp on it. The total number of ends in the warp is 420 and the weight of the empty beam is 63 lbs.

Solution:

Count Of warp yarn,

Length of warp in yds × number of ends
= …………………………………………………………………
Weight in lbs × 840

12000 × 420
= ………………………
240 × 840

= 25's cotton.

So, count of yarn on a back beam is 25s cotton.

2.
Total length of Yarn in warp,
= length of warp × number of ends

Example :
A warper’s beam produced on an improved modern high speed beam warping machine contains 39780 yds of warp with 420 ends. If the net weight of the warp on the beam is 663 lbs, calculate the beam count.

Solution:

Total length of Yarn in warp,

= length of warp × number of ends

39780 × 420
= ……………………….. (hanks)
840

= 19890 hanks

Count,

Total length of yarn in hanks
= ……………………………………………
Weight in lbs

19890
= ……………..
663

= 30's cotton

So, the beam count is 30s cotton.
