Is Cotton Dust Potential Correlated with Cotton Stickiness??

David T.W. Chun


ABSTRACT

Sticky cotton became a greater problem in the early 1990’s and researchers were concerned that possibly more dust would accumulate that would be released later during subsequent processing. This would be a potential problem in the processing of sticky cotton and might mean more frequent downtime for cleaning machinery and increased surveillance to remain in compliance with the Cotton Dust Standard. So a survey was conducted to determine if cotton dust potential is related to stickiness. A large number of samples with varying degrees of stickiness that was determined by the percent reducing sugar and the Thermodetector and Minicard rating method for stickiness, was collected and assayed for cotton dust potential. The stickiness levels and the associated cotton dust potential were compared. A small tendency for increased dust potential was observed when stickiness was measured by the reducing sugar and Thermodetector methods. But no difference was observed using the minicard stickiness rating method. Since the increased dust potential is small or practically no different from that of nonsticky cottons, additional adjustments to control cotton dust during processing is probably not necessary.
