FRESHER INTERVIEW QUESTIONS IN SPINNING MILL

INTERVIEW QUESTIONS FRESHER:-

What is Count ?

    No. of 840yards in pounds is called as Count.

What is Draft ?

    Thinning down the material.

    or

    Delivery surface roller speed / Feed surface roller speed.

What is TPI ?

    How much Twist in yarn per inch, Twist per inch (TPI)

What is TM ?

    TM is a relationship between yarn number (count) and turns per inch in the yarn.

Formula:-
TM = TPI X Square root of Count

RKM

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 RKM is the short expression for “Reisskilometer” – “Breaking-kilometre”, which is an unit out of date.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

LOW RKM REASONS

LOW RKM REASONS BLENDING OF MIXING TO BE ENSURED AND IF NECESSARY TUMBLING TO  BE DONE. 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. ...

HOW TO REDUCE CLASSIMATE FAULTS

REDUCING CLASSIMATE FAULTS 1) Count wise online Classmate classes wise results to be record on daily basis 2) Before allotting this work we want to educate quality investigator about Classmate faults and also class wise reasons we want to explain. While noting time investigator has highlight which class is having continuous higher side and same one communicate to that concern dept with reasons 3) We want to fix which classes we want to reduce 4) On daily basis monitoring we can get idea in which zone we r having problem and which zone we want to improve the work methods and process  5) Based on trend analysis we want to inspect process auditing and find out practical problems and also Training awareness we want to give to operators for reducing some classes  6) We can take process trials based on Online Classmate results  7) Regularly we want to compare daily Online results Vs Trial sample results for knowing Where we are Note: Choosing of quality investigator is import...
