Example 33.—Find the resultant counts of 2/32's cashmere or worsted folded with 21's skeins counts. State answer in skeins system.
Transfer worsted to skeins—
| 16 × 560 | |
| = 35 skeins. | |
| 256 |
By one method the counts is given by—
| 35 × 21 | 35 × 21 | ||
| = | = 13⅛ counts skeins. | ||
| 35 + 21 | 56 |
In this connection it might be useful to have the weight proportion of each, also the average counts if the two threads are not folded but placed side by side. Let the price of the 2/32's be 7/6 per lb., and that of the 21's skeins, 3/-per lb., when the cost per lb. of the combination is obtained as follows—
| 35 hanks of 35's | = 1 | lb. @ 7/6 | = | 7/6 |
| 35 hanks of 21's | = 1⅔ | lb. @ 3/- | = | 5/- |
| 35 hanks of folded | = 2⅔ | lb. | = | 12/6 |
For the counts 35⁄2⅔ = 13⅛ if folded, but if separate, number × 2 will give the average counts 13⅛ × 2 = 26¼ average counts.
The weight percentage of each constituent in the garment is stated thus—
| 1 | 1⅔ | ||
| × 100 = 37½ % worsted. | = 62½ % skeins. | ||
| 2⅔ | 2⅔ |
