INTRODUCTION
● Known as the 'heart of spinning', it is the second and stage of spinning.
● The carding stage is all about fibre individualisation of the cotton material leading to formation of sliver material.
● The efficiency of carding machines and spinning cans determine the end result of yarn produced, therefore, it is important to make the choice carefully.
WHAT IS CARDING?
● It is the process of removing clumps and locks from the cotton fibres that is received from blowroom and aligning them in parallel positions to create sliver.
● Carding is done to boost the processing efficiency levels, and render the bestquality yarns.
● In order to maximise the productivity of carded sliver, mills should always use advanced carding machines and quality-assured HDPE spinning cans, with high dimensional accuracy for efficient carding.
● The lapping stage eliminates impurities, the willowing process loosens the fibre, and then they are individualised into proper strands.
IMPORTANCE OF CARDING STAGE
● The carding process eliminates all the neps that are generated in the mixing and the blowroom phases.
● Ensuring optimal cleanliness of cotton lies at the very heart of quality yarn production which is achieved during the carding phase.
● Fibre blending is also another extremely important result of the carding process.
● The sliver produced during this stage is very delicate in nature, hence the use of mechanically strong card cans and spinning cans is required.
ROLE OF CARDING MACHINES
● After fibre individualisation and parallelisation, the remaining neps and impurities are removed from the cotton fibre.
● After the short fibres are eliminated as well, the fibre blending and orientation is done.
● Then finally, the slivers are formed in the carding machine, preparing them for the next stage, i.e. drawframing.
● Given the importance of carding in the overall textile & yarn spinning process, it is only natural that leading OEMs are consistently coming up with advanced features in their carding machines.
