4. Definition Count is a numerical expression which defined the coarseness or fineness of yarn.

5. Yarn count systems

6. Yarn count systems Direct System: The direct system of yarn count is based on measuring the weight per unit length of a yarn. Count,D = =

7. Classification of Direct System Tex: Weight in grams of 1 km yarn. Denier: Weight in grams of 9 km yarn. Jute/Wool/Hemp Count: Weight in pounds of 14400 yards yarn.

8. Problems The weight of 100 km yarn is 1 kg. Find out the yarn count in Tex, Denier and Jute count?[1kg=2.2pounds, 1m=1.091yards]

9. Yarn count systems Indirect System: The indirect system of yarn count is based on measuring the length per unit weight of a yarn. Count,N = =

10. Classification of Indirect System English Count, Ne: Length in hanks of 840 yards per pound. Worsted Count, Nw : Length in hanks of 560 yards per pound.

11. Classification of Indirect System Yorkshire Count, Ny : Length in hanks of 256 yards per pound. Metric/British Count, Nm: Length in kilometers per kg.

12. Problems The weight of 1200 yards yarn is 0.1 pounds. Find out the yarn count in Ne, Nw , Ny , Nm.

13. Problems The weight of 1200 yards yarn is 0.1 pounds. Find out the yarn count in Ne, Nw , Ny , Nm.

14. Count conversion

15. Direct To Direct Count,D = For the same sample, (1) Again,

16. Direct To Direct By using equation no. (1) we get, And, Again,

17. Indirect To Indirect Count N= For the same sample, (2)

18. Indirect To Indirect By using equation no. (2) we get,

19. Indirect To Indirect Again

20. Direct To Indirect Indirect Count, N= Direct Count, D= For the same sample, (1)

21. Direct To Indirect By using equation no (1) we get,

22. Direct To Indirect Using 1 again
