SECOND STEP: CONVENTIONAL CARDING PROCESS
THE MOST IMPORTANT PROCESS IS THE CARDING BECAUSE OF IT DEPENDS THE QUALITY OF THE YARN
After resting the raw material, starts the carding process, the raw material is sent through a pneumatic process to the charger of the assortment, which with an automatic weighing which leaves the raw material tuft in the carding machine and then starts the carding process. The raw material goes through the different cylinders and hooks which open the fibers, combing them and cleaning them because of the possible impurities that the raw material could have (the wool can be shivey, the cotton has vegetable, some sand, etc). Then the raw material through the different cylinders and drums become parallel and homogeneous converting them in a flat sheet. This phase is called the carding scribbler.
This process is repeated again in the next phase, second breaker, the flat sheet is sent to the other carding group through the transporter which repeats the same operation but in this case is a flat sheet of fibers that goes through different cylinders and hooks in order to improve the perfectionism and giving a major parallelism. The flat sheet produced goes through each carding drawing frame, last phase of the carding process, which arrives to the flat sheet dividers which splits up and divides and with this it start to get the shape of a yarn. This yarn is still a twist less yarn and still does not have resistance and it is called sliver. The sliver gets rolled in the winder and after this starts the next process which is the spinning.
