Carding
Carding is one of the most important operations in the spinning process as it directly determines the final features of the yarn, above all as far as the content of neps and husks are concerned. There are many objectives of the carding process and these can be summarized as:
§ Opening the tufts into individual Fibres.
§ Eliminating all the impurities contained in the Fibre that were not eliminated in the previous cleaning operations.
§ Selecting the Fibres on the basis of length, removing the shortest ones.
§ Removal of neps.
§ Parallelizing and stretching of the Fibre.
§ Transformation of the lap into a sliver, therefore into a regular mass of untwisted Fibre.
