Reducing fly contamination in single jersey circular knitting machine

Abstract

The aim of this is to reduce Fly contamination from knitted fabric and increase the quality of the fabric. Fly 
contamination problem was found on dyed fabric which were being produced in three machines of the JFL floor. 
From the quality team data of fly contamination of 10 days was taken of those three machines. At first some 
procedures were applied to find out the causes of the problem (Matrix, Pareto Chart,5W1H). After find out the 
major causes, their solutions were also found and being applied on the machines. Such as maintaining proper 
polyethene on the machine as separator, making duster and proper use of it, counselling and giving training to the 
helpers. The costs were being noted while the solutions were applied in order to do so. Besides helpers and operators 
were being monitored time to time as they remain idle and were shown gossiping with each other’s whereas they 
had to clean the dusts from the machines. After doing all the things it was seen fly contamination reduced in an 
approximate range. These things were monitored about 12 days and the data of 10 days after implementation was 
also taken. The data of 10 days before implementation and 10 days after implementation was compared. When it 
became confirmed that fly contamination reduced, then the cost benefit was calculated. Doing all the things, it 
became clear that the aims of the project were achieved.
