Carding
Carding process in the textile industry, the process of separating individual fibers, using a series of operations, that causes many of the fibers to lie parallel to one another while also removing most of the remaining impurities is called carding. After the carding operation, we get a carded sliver for yarn preparation. It is a mechanical process for fiber processing.
Carding process in the textile industry
Carding process in the textile industry, the fibers are separated and then assembled into a loose strand sliver or tow. The cotton comes off of the picking machine in laps and is then taken to carding machines. The carders line up the fibers nicely to make them easier to spin. The carding machine basically carries a large roller with smaller ones around it. All of the rollers are covered in small teeth, and as the cotton progresses further on the teeth get finer i.e. closer together. The cotton leaves the carding machine in the form of a sliver: a large rope of fibers.
Carding
in a broad sense can refer to these four processes-
Willowing-
loosening the fibers;
Lapping
- removes dust to create a flat sheet or lap of cotton;
Carding
- a sliver on a thick rope of 1/2 inch diameter with shoulders in the litter
lap;
Drawing-
where a drawing frame combines 4 slivers into one, repeated for increased
quality.
