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 RKM is the short expression for “Reisskilometer” – “Breaking-kilometre”, which is an unit out of date.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?

LOW RKM REASONS

By
LOW RKM REASONS TO START WITH SLIGHTLY RICHER MIXING AND BACK TO USUAL MIXING% GRADUALLY. AVOID BYPASSING OF THE BEATERS. CHANGING OF THE CARD LINES TO BE AVOIDED . TO START WITH HIGHER NOIL% AND REDUCE GRADUALLY TO USUAL    IF REQUIRED. SOFT WASTE ADDING TO BE AVOIDED FOR FIRST 3 OR 4 MIXINGS. IN SIMPLEX M/C CHECK THE FOLLOWING     a) FALSE TWISTER CONDITION     b) FLOATING CONDENSER CONDITION .     C) DAMAGE COT/APRON .     d) DEFECTIVE SADDLES .     f) TOP ARM LOAD .     g) PRESSER EYE CONDITION .     h) FLUFF ACCUMULATION ON FLYER HOLE .     i) BOBBIN CLEARANCE VARIATION .     j) CONE DRUM NOISE     k) FEED CAN CONDITION         l) SLIVER SPITING . IN SPINNING M/C CHECK THE FOLLOWING:     a) CRISIS-CROSS ROVING .     b) BOBBIN HOLDER ROTATION .     C)DAMAGE COT/APRON.     d)DEFECTIVE SADDLES.     f)TOP ...
