COT/ROLLER CLEANING IN
SPINNING MILLS |
The constant exposure to fibres and fibre impurities such as cotton seed oil in the presence of dust make the regular cleaning of rubber cots and metal rollers in yarn
spinning mills a necessity. The requirement appears to increase with rising humidity and is thus more prevalent in coastal areas. Although the raw material poses a tremendous fire risk in itself, suprisingly some flammable substances have been found as cleaning agents in use too.

found already in use for cleaning of rubber cots and metal rollers. No performance assessment of these products has been carried out yet.

HAZARDS TO CONSIDER
|
 |
|
Every substance has limitations. While every solvent is toxic to a certain extent, the harmfulness varies from one substance to another. A given substance may be hazardous on skin contact, be a fire hazard, harm the environment and/or cause cancer (i.e. red category).
