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

Production calculation formula of blow room:

Blow room production per hour,
                                                            60
Surface speed of calendar 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
Production calculation of Ring Frame = …....………………………………...... X Efficiency
                                                                       T.P.I X 36 X 840 X Count
