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)

How to calculate fabric GSM from given Fabric:

                                GSM from Given Fabric = Fabric Weight in Grams / (Fabric Width * Fabric Length)

How to calculate Fabric GSM in Textile Weaving from Fabric Construction:

                               (Ends + Picks) * 25.537 / Average Count
