Example 41.—Find the particulars for a fabric containing three yarns used, one of each in succession, where the take-up of each thread varies in the fabric as shown. This take-up of different yarns in knitting is frequently neglected in calculations, but obviously should be carefully taken into account for it has a very direct influence on the weight.

1 - 40's yarn with take-up of 1·25 for normal fabric.

1 - 30's yarn with take-up of 1·50 for normal fabric.

1 - 12's yarn with take-up of 2·25 for normal fabric.

We proceed by stating the length of hank in the ratio of the various take-ups thus—

225 hanks of 12's=18·75lb.
150 hanks of 30's= 5lb.
125 hanks of 40's=3·12lb.
125 hanks normal=26·87lb.

Working out percentages in the usual way from the column of weights we find that—

40's yarn = 11·4% of weight.
30's yarn = 18·6% of weight.
12's yarn = 70% of weight.
