Spinning experiments were conducted to study the impacts on fiber processing of
alternative types of honeydew contamination and confirm the hypothesis that trehalulose
(mostly present in whitefly honeydew) is the main source of concern when attempting to
spin sticky cottons. Spinning tests using Suessen Fiomax 1000 and Suessen EliTe frames
showed that both types of honeydew are, at least partially, cleanable and that the whitefly
honeydew droplets are broken into smaller particles during the opening, blending, carding,
and drawing operations. Regarding yarn quality, except for the yarn nep count, aphid
honeydew contamination did not translate into negative effects on both yarn quality and
productivity up to 26 high speed stickiness detector (H2SD) spots. For whitefly-
contaminated cotton even 12 H2SD spots had a drastic negative impact, producing
unacceptable yarn quality and productivity. Therefore, the threshold for acceptable
performance in the mill for whitefly-contaminated cotton should be set well below 12 H2SD
sticky spots.
