  16. Delivery speed = 100m/min Lap hank in grain/yds =750 Lap hank =0.0098 Efficiency =85% Waste = 2.0% Stoppage time = 5% Production of lap former = production of comber ×(100+waste)/100 =809.0827×1.15=930.45 lbs Production per hour = deli speed*lap hank (grain/yd)*60*Eff% / 7000 = 100*1.09*60*750*85/7000/100 =595.6071 lbs Number of Lap former = 930.45/595.6071 =1.57 No. of installed lap winder =1.57 *(100+stoppage time)/100 =1.57*1.05 =1.65 that it required 40% So Lap winder required 1.65*40/100=0.66 = 1 Consultant: Aftab Global Textile and Nannu Spinning Mills

  17. Draw frame Delivery roller speed = 450 m/min Sliver hank = 0.14 Delivery head per frame = 2 Efficiency = 90% Waste = 2% Stoppage time = 6% Production of draw frame = Super lap former production *(100+waste)/100 = 595.6071 *1.02 =607.51 lbs Production /hour/frame = deli speed*60*eff%*No. of head/840/sliver hank =450*60*85*2/840/.14/100 = 390.3061 lbs Running Draw frame = 607.51/390.3061 =1.55 Install draw frame = 1.55 ×(100+stoppage time)/100 =1.55*1.06=1.65 = 2 Consultant: Aftab Global Textile and Nannu Spinning Mills

  18. Carding section: Doffer diameter = 27 inch Doffer speed = 40 rpm Sliver hank = 0.12 Efficiency = 90% Wastage = 4% Average ideal time = 10% Carding production = Draw frame production ×(100+Waste)/100 = 607.6071*(100+0.5)/100=607.6071*1.005= 610.65 lbs Production/hour/machine =pie *doff dia*doof speed*60*eff%/36/840/sliver hank =3.14*27*52*60*90/36/840/.12/100 = 65.65lbs Running Carding m/cs= 610.65/65.65 =9.31 Installed Carding Machines =Running Carding machines *(100+avg stoppage time)/100 =9.31*1.10=10.23 = 10 set Consultant: Aftab Global Textile and Nannu Spinning Mills

  19. Blow Room Section Calendar roller Diameter (C.R.D) = 9.5 inch Calendar roller speed (C.R.S) = 12 rpm Lap hank = 0.0016 Waste = 4% Efficiency = 85% Scutcher / blow room line = 2 Average ideal time = 12% Blow Room production = Carding production×(100+carding waste)/100 610.65*(1.04)=635.07 lbs Pro./hr./Scutcher of Blow room = pie*C.R.D*C.R.S*60*Eff% / 36/840/.0016 = 3.14*9.5*12*60*85/36/840/.0016/100= 377.314 lbs Running Scutcher = blow room prod/prod/hr/scutacher of blowroom = 635.07/377.31 =1.68 Installed scutcher = 1.68 *(100+avg ideal time)/100 =1.68*1.12=1.88 =2 No. of Blow room line = 2/2 = 1 Consultant: Aftab Global Textile and Nannu Spinning Mills

  20. Autoconer section: No of Drum per autoconer =60 Speed per drum =1350 m/min Yarn Count=52 Ne waste = 1% Efficiency = 75% Average ideal time = 5% Winding production = ring prod×(100-ring waste)/100 791.25*0.98= 775.425 lbs Pro./hr./drum =drum speed*eff%* time/840/count =1350*75*60/840/52/100 =1.49 lbs Running drum =775.425/1.39 =557.54 Running aotoconer machine = 557.54/60 =9.29 Installed autoconer = 9.29*(100+avg ideal time)/100 =9.29*1.05=9.75 No. of autoconer = 10 Consultant: Aftab Global Textile and Nannu Spinning Mills

  21. Summary: Number of required machines for 42528 spindles & 52S Count Cotton yarn: " Blow room line = 1 (2 Scutcher) " Carding machines = 10 " Draw frame = 02+02 " Super lap former =01 " Comber = 04 " Simplex = 10 " Ring frame = 22(1200)+16(1008)=38 “ Autoconer = 10 Consultant: Aftab Global Textile and Nannu Spinning Mills
