Production Calculation in Spinning is one of the principal tasks for the production manager who is responsible for spinning the floor. Maximum time textile engineers forget the common spinning production calculation formula. In this article just I want to try to give a production calculation formula in cotton spinning.

Spinning is a major and ancient part of the textile industry. It is part of the textile manufacturing process where three types of fiber are converted into yarn. Then fabrics, undergo finishing processes such as bleaching to become textiles. To complete finished products (yarn) in spinning every textile personnel must know some formulas.

**Production calculation formula of blow room:**

Blow room production per hour,

………………………………………………………..60

The surface speed of c. roller x ……..…………………… x Eff. % x Waste% x No. of scatcher

…………………………………………….36 X 840 X Hank

**Production calculation of carding:
**………………………………………………………………………………………60

Production of carding = Surface speed of doffer x …………..………….…………. x Effi% x Waste%

………………………………………………………………………..36 x 840 x Sliver hank

**Production calculation of Drawing:
**…………………………………….Front roller surface speed X 60 X Efficiency% X Waste% (lb/hr)

Production of Drawing = ………………………………………………………………………………………………

…………………………………………………………………..36 X 840 X Hank

**Production calculation of lap former:
**……………………………………….πDN…………….lap count (grain/yard)

Lap former production =……….…….. x 60 x …………………..………….. x η x no of machine(lb/hr)

…………………………………………36……………………………..7000

**Production calculation of Comber:
**Production of comber per day,

…………………………………………………………………………………………………….100-Noil%

= Nip/min X Feed/nip X No. of head X Feed lap weight X Efficiency X .…………….. X 60 X 24

……………………………………………………………………………………………………………100

**Production Calculation Formula of Speed Frame or Simplex:**

………………………………………………………Flyer speed (rpm) x 60 x 8 x No of flyer x Efficiency

Production Calculation of Simplex = …………………………..…………………………………………………

……………………………………………………………………TPI x 36 x 840 x Roving hank

**Production calculation formula of Ring Frame:**

……………………………………….Spindle r.p.m X 60 X 8 X No of spindle

Ring Frame Production = ……………………………………………………………. X Efficiency

…………………………………………………T.P.I X 36 X 840 X Count
