SPINNING LEARNERS

Technical Spinning Information and Formulas :-   1) Constant  One pound is 7000 grains = 453.59 grams One skein is 120 yards = 109.7 meters One yard = 36 inches = 0.9144 meters One hank is 840 yards = 768.1 meters The yarn count and hank roving number equals the number of hanks in one pound. To find the hank roving number from number of grains per yard: Divide 8.33 by the number of grains per yard. Hank roving number = 8.33 x yard Grains   2) To find the speed of the front roll Divide the revolutions per minute of the spindle by the product of the twist per inch, multiplied by the circumference in inches of the front roll Front roll speed = S pindle R.P.M  diameter of front roll  x  T. P.I   3) To find the Spindle Speed Multiply the R.P.M. of the front roll by the twist per inch and this product by the circumference of the front roll. Spindle speed = FRS   x T.P.I x  X diameter of front roller   4) To find the standard twist per inch Mul...

RINGFRAME DRAFT:-      HI FRIENDS TODAY WE SEE IN THIS BLOG HOW TO GIVE DRAFT IN RINGFRAME IN SIMPLE METHOD. DRAFT:- Delivery/Feed = Draft      Here we give formula for calculation draft. But actual draft(Running draft) is higher than calculated draft because of the slippage. Example:-     If we run new count as 36s count from simplex hank 0.88 example given below.     First we need to find slippage of running m/c  DELIVERY COUNT = 40 FEED HANK = 0.88 Calculated draft is 45.45 in case running draft is 48.21 we want found how much percentage is slippage. FORMULA:- Slippage  =  Actual draft/Calculated draft*100-100 = 48.21/45.45*100-100= 6.073% New count draft = Count/Feed hank/100*(100+slippage) =  36/0.88 /100*(106.073) = 43.393

MPM FORMULA:- PRODUCTION FORMULA 8HRS = MPM*1.094*8*60/840/2.20456/HANK*EFF/100*NO. OF DELIVERY MPM HANK FORMULA :- MPM HANK FORMULA 8HRS = MPM*1.094*8*60/840/*EFF/100*NO. OF DELIVERY HANK TO KGS FORMULA :- HANK TO KGS FORMULA 8HRS = HANK*CONSTANT  CONSTANT :- 1/2.20456/HANK*EFF/100*NO. OF DELIVERY SHORT MPM FORMULA :- PRODUCTION FORMULA 8HRS = 0.2835 * MPM/HANK*EFF/100*NO. OF DELIVERY What is 0.2835? :- 1.094*8*60/840/2.20456 = 0.2835

DRAFT :-       Reducing the Linear density of material by passing the successive pair of the rollers roating at higher speeds. This process include the silver passing over the rollers. The roller rotates speed faster than older one that means front speed is higher than middle roller middle roller speed is higher than back roller.  Break draft Main draft Total draft Thin down the material is called as draft.  Surface speed of delivery roller / Surface speed of feed roller Delivery hank / Feed hank Break draft :-     The break draft is in the range between the 1.03 to 2.03. Surface speed of 2nd roller / Surface speed of 3rd roller Main draft :- Surface speed of Front roller / Surface speed of  2nd roller Total draft :- Break draft + Main draft = Total draft

RINGFAME BREAKS STUDY CALCULATION   :-                In this blog we discuss about  how to calculate the Ringframe breaks study formula. Ringframe breaks was calculated as Breaks per 100 Spindle in one hour. Formula  :- No. of breaks in study(one doff)  ÷  Total time of study  ÷  Total No. of spindle × 60(min) × 100 spl For Example  :- Breaks = 160 Study taken time = 117 mins Spindle in ringframe = 1632 = 160 ÷117 ÷1632 × 60 × 100 = 5.03 Breaks/100spindle/Hour

WARPING BREAKS  :-               In this blog we discuss about  how to calculate the warping breaks. We need some details for calculating warping breaks is given below. 1 Need how much cone creeled in warping machine. 2 What is the set length beam. 3 How much beam planned to run. 4  And finally how much breaks happened in study. For Example :- Cone creeled in warping machine = 788 Set length of beam = 35500 No. of beam planned to run = 7 Beam No. of breaks in study = 35 (7 Beam) Formula  :- S et length × No.of beam × No. of cone creeled in warping machine= Total length of meter running in Warping No. of breaks in study(7 Beam)  ÷ Total length of meter running in Warping × 1000000 = Warping breaks/Per Million = 35500 × 7 × 788 = 195818000( Total length of meter running in Warping) = 35 ÷ 195818000 × 1000000 = 0.179 Breaks /Per Million.

LENGTH CORRECTION FACTOR  :-               Basically  LCF length correction factor is used in Autoconer or Linkconer in spinning mill. used for maintain weight of the package. What ever count we are running in a spinning mill we give the set length of the package. The weight of the package is change by day to day due to so-many reason one of reason is RH (RELATIVE HUMIDITY), When the RH is going to high the weight of the package will be goes to high. Rh is going to low the weight package is go to low. So we need to maintain length and weight of the package. so we need to change LCF is requirement. HOW LCF IS WORKING  :-               Generally  LCF working is length concept for example we run 40s Count set length is 169500 meter. If LCF is 1.000 is after complete the 169500 meter wound doff length achieved . incase 1.010 is LCF  169500 × 1.010=171195 meter wound after that doff lengt...

  SHORT FORMULA METER TO WEIGHT:- FORMULA = 0.59 × METER ÷ HANK ÷ 1000 EXAMPLE:- Meter = 5000 Hank = 0.125  = 0.59 ×5000 ÷0.125 ÷1000 =23.6306 Kg 

SHORT FORMULA WEIGHT TO METER :- FORMULA = 1693 × HANK × WEIGHT IN KG EXAMPLE:- WEIGHT = 23.6306 Hank = 0.125 = 1693 × 0.125 ×23.6306 =5000 METER

  SPINNING GPS:- FORMULA = 7.2*SPINDLE SPEED /TPI/COUNT EXAMPLE:- Spindle speed in RPM= 19000 Count = 40s  Tpi = 22.5 = 7.2 ×19000 ÷40 ÷22.5 =152 GPS

  LINKCONER CONE LENGTH IN METER:- FORMULA =  1.693*COUNT*CONE WEIGHT IN GMS EXAMPLE:- Cone weight = 2kgs Count = 40s = 1.693 ×2000 × 40 = 137133 METER This length is calculated as formula but Actual length is high  due to slippage of the machine from 1.5% to 3.0% 

TRAVELLER SPEED:- FORMULA = SPINDLE SPEED* 3.14* RING DIA /1000 EXAMPLE:- Spindle speed = 22000 RING DIA = 36 =22000 ×3.14 ×36 ÷1000   = 2486.88

  FRONT ROLLER RPM:- FORMULA = SPINDLE SPEED /TPI/3.14 EXAMPLE:- Spindle speed = 22000 Tpi = 28 =22000 ÷28 ÷3.14   = 250 RPM

FRONT ROLLER METER/PER MIN :- FORMULA = SPINDLE SPEED /TPI/39.3701 EXAMPLE:- Spindle speed = 22000 Tpi = 28 =22000 ÷28 ÷39.3701   = 19.96 Meters/Per min. The above given 39.3701 is convert meter to inch.

REELING FORMULA Index wheel*1.5*7*no of hanks per Knott*no of Knott per bundle/840/count/2.204 Cop content formula Formula : 3.25 X L X D2 (D square)  L = Lift  D = Full dia of cop or Ring dia  Ex = 3.25*6.7"(1.5"*1.5") = 48.9 gms

PRODUCTION FORMULAS :-     In spinning mill we use production formula in short method. I recommend to use  formula in elaborate. First we need some basic details is given below GENERAL:- 1   METER = 1.094 YARD 1 LEA = 120 YARD 7 LEA = 840 YARD 1 KG = 2.20456 POUNDS 1 CM = 10 MM 1 INCH = 2.54 CM 1 INCH = 25.4 MM     In basically we use two formula mostly. one is where we have METER PER MIN and another one is where we have REVOLUTION PER MIN MPM FORMULA:- PRODUCTION FORMULA 8HRS = MPM *1.094*8*60/840/2.20456/ HANK * EFF /100*NO. OF DELIVERY EXAMPLE:- Delivery speed in MPM = 150 Hank = 0.120 Eff = 96%     In the above formula 8 means 8Hrs(Per shift), 60 means 60 Minutes = 150×1.09×8Hrs×60Min÷840÷2.20456÷0.120×96÷100*1 =339 Kgs/Pershift RPM FORMULA:- PRODUCTION FORMULA 8HRS =  RPM *8*60/36/840/2.20456/ COUNT / TPI *EFF/100*No. of delivery EXAMPLE:- Spindle speed in RPM = 1350 Hank = 1.14 Tpi = 1.59 Eff = 80%    ...
