Once cotton is ginned, and while it is being baled, a sample of cotton is taken from both sides of every bale. Samples from the two sides are put together and given a tag with a bale number and barcode that directly relates to the originating bale. These samples are then rolled up in plastic in groups of 50-60 with consecutive bale numbers and then sent to the classing facility for classification.
Upon arrival, the samples are conditioned as per international standard requirements before the classing process begins. The samples are then taken to the High Volume Instrument (HVI) machines where testing is carried out to determine various fibre properties and then on to the manual classing stations where the the classification of colour and leaf is performed.
After classification is complete, the results of the fibre measurements are immediately relayed to growers, merchants and any related parties.
