Identification of problem factors in dyeing knitting with root cause analysis and failure mode and effect analysis

The manufacturing industry sector has an important role in the national economy, especially in the textile sector. The value of textile exports in 2017 experienced a significant increase of around 15%, but in 2017 to 2019 there was a continuous decline. This is because almost the whole world is looking for the latest trading systems and due to the growing technology. This study aims to find the factors that cause defects in dyeing knitting products. The analytical methods used are Root Cause Analysis (RCA) and Failure Mode and Effect Analysis (FMEA) involving experts. The results showed that there are three defects in dyeing knitting. Factors causing problems with dyeing knitting defects include Striped yarn, Auxiliary spot, and Striped dip. Based on the FMEA analysis, the priority problem occurring in the Striped Yarn defect is the troubled fabric in the knitting section with an RPN value of 180. The main cause of the Auxiliary Spot defect is a dirty machine with an RPN value of 216. The main cause of the Striped Dip defect is dirty gray cloth with an RPN value of 216.
