Proof for Proper Structure of Given Cloth. 2/32's worsted =8,960 yards per lb., and i/8,960--10 per cent. =85 threads of 2/32's worsted will lie side by side in one inch. a Answer.--64 threads per inch must be used, and since 3,840-=-60=64, this is the number of ends used per inch in given cloth, the structure of the given cloth is perfectly balanced. 2. Required Cloth. b. Find the Proper Texture for Warp. 2/26's worsted =13X560=7,280 yards per lb. 1/7,280=85.3 less 10 per cent. (8.5)=76.8 diameters of threads of 2/26's worsted will lie side by side in one inch. 3.... 76.8X6 3 twill=2 points of interlacings in one repeat. Thus: g-i-2--460.8-=-8=57.6, or practically--Answer.--58 threads per inch must be used. a. Ascertain Weight for Required Cloth. Using the same width in reed as in the given cloth (60 inches). 58 X 60=3,480 ends must be used (8 per cent. take-up). 100:92:: x: 3,480. 348,000-5-92=3,782 yards required for one yard cloth from loom. 2/26's worsted=7,280 yards per lb.-5-16=455 yards per oz.; thus: 3,782-=-455=8.3 oz. warp yarn required. Using 61 picks we find--61 X 60=3,660 yards filling (2/32's worsted) wanted. 3,660-=-455=8 oz., weight of filling yarn wanted. Warp, 8.3 oz. Filling, 8.0 oz. Answer.--16.3 oz., total weight of cloth (exclusive of selvage) from loom, being exactly the weight wanted. To Find the Number of Ends per Inch in the Required Cloth. The two examples previously given will also assist us to illustrate the next rule; i. e., " Finding number of ends per inch in the required cloth." Rule.--The weight per yard of the required cloth is to the weight per yard of the given cloth in the corresponding ratio of the warp ends per inch in the given cloth to the warp ends per inch in t...
