Th t i t t f ti ki i d t• The most important cause of stickiness is due to these entomological sugars.

• Honeydew has now become one of the maincontaminants present in cotton.p

• Sticky points remain in the cotton from the field up toh i i h h d ithe spinning processes where they cause productionand quality losses.

• The behavior of contaminated fibres duringprocessing is highly dependent upon the quantity andp g g y p p q ythe type of the main sugars present in fibres

Introduction of the bibliography

• In order to allow everyone to learn more about this contamination, we decided to prepare this extract of the available literature. We retained around 214 references out of thousands of available references, focusing on the cause of stickiness, on the possible means of evaluation and/or measurement and on major consequences during fibre processing.

• The initial bibliography covers a period going from g p y p g gthe 1960’s to 2008.
