An expert system for monitoring and controlling loom operation helps to avoid set marks in woven textiles by setting restart parameters, increasing quality and reducing costs and waste.
 

Recent years have seen the European textile manufacturing industry losing out to less developed countries with lower labour costs. European textiles have only remained competitive on the basis of their high quality, but production methods have not always kept up with quality demands. Imperfections caused by process failures mean products must be sold as second quality goods or even thrown away.

This project was aimed at developing an expert system for monitoring and controlling loom operation, specifically to help avoid set marks in woven textiles. Set marks are caused when a yarn break stops the loom automatically. The break must be repaired and then the loom is restarted. This can leave a visible defect across the entire width of the material. Set marks can be avoided by the careful setting of loom parameters before restarting. Previous to this study, this had to be done manually by highly skilled workers. The new software analyses the particular operating situation and determines the restart parameters automatically.

This is the first on-line system to be developed for avoiding the appearance of set marks in textile products. The prime partner, the Belgian company, Picanol, is now using the system and has seen significant increases in production quality and savings.
