SPINNING MILL SHORT FORMULA EXPLANATION

By

 SPINNING MILL SHORT 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


Mostly Spinning people use short formula like

0.2835×Delivery speed in mpm÷ Hank for MPM to Kgs

And 1693×1.890(weight in kg)×count for Find autoconer cone length.

Where its comes?

First we take short formula 0.2835

Here we use 0.2835 and MPM and Hank. What was the actual formula

MPM*1.094*8*60/840/2.20456/HANK*EFF/100*No. of delivery

so we omit the MPM And hank in this formula

1.094*8*60/840/2.20456 = 0.2835.


Second we take short formula 1693

We use formula the above same

Length*1.094*8*60/840/2.20456/count = Weight

But here we need the Length. So reverse the formula

840*2.20456*1.094 =1692.71 = 1693.


ELABORATE FORMULA

 In basically we use two formula mostly. one is where we have METER PER MIN (MPM) and another one is where we have REVOLUTION PER MIN(RPM)

MPM FORMULA:-

PRODUCTION FORMULA 8HRS = MPM×1.094×8×60÷840÷2.20456÷HANK*EFF÷100×No. of delivery

RPM FORMULA:-

PRODUCTION FORMULA 8HRS=  RPM×8×60÷36÷840÷2.20456÷COUNT÷TPI*EFF÷100×No. of delivery

COMBER NPM PRODUCTION FORMULA 8HRS:-

FORMULA = NPM×8×60×NO. OF HEADS×FEED PER NIP× GMS ÷PER METER×(100-NOIL)÷1000×1000×100×EFF÷100

COMBER FEED PER NIP FORMULA :-

FORMULA = 3.14×BOTTOM ROLLER DIA÷RATCHET WHEEL TEETH

RKM

By
RKM INFORMATION This can be expressed by the “Length of yarn in km” at which yarn will break of its own weight”. This is equivalent to breaking load in g/tex. RKM is the short expression for “Reisskilometer” – “Breaking-kilometre”, which is an unit out of date. E.g.: a Cotton-yarn with 15 RKM means, it would break of its own weight, if you wind off 15 km of the yarn and hang it up in 15 km. Nowadays it is common practice, to use the unit Centi-Newton per Tex (cN/Tex) or gram-force per Tex (gf/Tex). RKM and cN/Tex or gf/Tex are practically the same (a slight difference would be there)   SINGLE YARN STRENGTH (Breaking force) :  This is the force required to break a strand of single yarn. It is expressing Centi-Newton (cN).     STRENGTH (Tenacity) : The Tensile Strength expressed as force per unit linear density is called Tenacity. This is normally expressed as gram force per tex (gf/tex).   CSP (Count Strength Product) : CSP, the bundle strength...

HOW TO CALCULATE YARN DIAMETER

By
HOW TO CALCULATE YARN DIAMETER     The diameter of  yarn can be calculated by 1divded 28 Square root of Count is called as Diameter of yarn in Per inch. Example :-      Count - 20s & 40s Formula:- 1/28 Square root of  Count = Diameter of inch 28Square root of  20 = 125.22 1/125.22 = 0.007986 Per inch 0.007986 x 25.4 = 0.203 So the diameter of yarn is 0.203 Formula:- 1/28 Square root of  Count = Diameter of inch 28Square root of  40 = 177.088 1/177.088 = 0.005647 Per inch 0.005647  x  25.4 = 0.203 So the diameter of yarn is 0.143 Then 1Divded 28 Square root of count why we apply Here?
