Frequently Asked Questions | FAQs

What is the role of fine cleaning in blow room?

In the blow room line of a textile mill, the role of fine cleaning is to remove any remaining impurities from the cotton fibers before they are further processed.
After the initial opening and cleaning process in the blow room, there may still be some impurities such as dust, dirt, and short fibers present in the cotton fibers. Fine cleaning is the process of removing these remaining impurities by passing the cotton fibers through a series of machines designed to remove them.
The machines used in fine cleaning can vary depending on the specific requirements of the mill, but typically include machines such as fine cleaners, card cleaners, and ultra-cleaners. These machines use various mechanisms such as air suction, beaters, and screens to remove the impurities from the cotton fibers.
The role of fine cleaning is important as it ensures that the cotton fibers are as clean as possible before they are further processed. This can help to improve the quality of the final yarn or fabric produced and can also help to reduce the risk of defects or issues during subsequent processing stages.
