What is Hank in Textile: Hank = 840 Yards
What is count in Textile Spinning: Count = Number of hanks in one Lbs of yarns
What is CN in Textile Spinning: 01 CN = 0.9807 Gram
How to calculate yarn weight in Textile: Grams / Yard = 0.54 / Count
How to Calculate IPI (Imperfactions): I.P.I = Thin(-50%) + Thick(+50%) + Neps(+200%)
How to calculate CLSP of yarn In Textile Spinning: COUNT = (Count * Lea Strength) or
(RKM / 0.0064) or (SYS * 120 * Count/453.6)
How to calculate RKM of yarn in Textile Spinning: R.K.M = (CLSP * 0.0064) or (CLSP / 156.2)
How to calculate single yarn strength of yarn in textile Spinning: S.Y.S = RKM * 1000 / 1.6934 / Actual Count
How to calculate twist per inch TPI of yarn in Textile Spinning: T.P.I = T.M * √(Count)
How to calculate production of Carding department in Textile Spinning:
Production in Kgs / Hour = ( Delivery Speed M per Mnt * 1.0936 * 60 * Efficiency) / (Hank * 36 * 840 * 2.20462)
Draft = Feed weight in grams per meter / Sliver weight in grams per meter
How to Calculate Break Draft of Draw Frame in Textile Spinning:
Break Draft = Surface speed of 2nd roller / Surface speed of back roller
How to calculate main Draft of Draw Frames in Textile Spinning:
Main Draft = Surface Speed of 1st Roller / Surface Speed of 2nd Roller
How to calculate Total Draft of Draw Frame in Textile Spinning:
Total Draft = Surface Speed of Delivery Roller / Surface Speed of Feed Roller
How to calculate the production of Draw Frames in Textile Spinning:
Production in Kgs per Hour = (FRD * FR RPM * 3.14 * 60 * Efficiency * ND) / (NE * 840 * 36 * 2.20462)
How to calculate T.P.I of Simples and Ring Frame in Textile Spinning:
TPI (Twist per Inch) = Spindle Speed / Front roller surface speed in inches per minute
How to calculate Spindle Speed of Ring in Textile Spinning:
Spindle Speed = M/Minute * TPI * 39.37
How to calculate Hanks Delivered in Textile Spinning:
Hank Delivered = Spindle Speed / (TPI * 62.89)
How to calculate Ring Traveler speed in Textile Spinning:
Ring Traveler Speed = (Spindle Speed * Ring Dia MM * 3.14) / (60 * 1000)
How to calculate Ring Frame Speed in Textile Spinning:
Ring Frame production = (Spindle Speed * 60 * 24 * No of Spindles) / (Count * TPI * 840 * 36 * 2.20462)
How to calculate Auto Cone / Winding production in Textile Spinning:
Production in Kgs per Hour = (Delivery Speed * 1.0936 * 60 * Efficiency) / (NE * 36 * 840 * 2.20462)
