these entomological sugars.

contaminants present in cotton.

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
