PT Superbtex installs flaw detector to contain contamination in polyester

The raw material for spinning synthetic fibers originates from well-controlled processes in chemical plants. This is why contamination with foreign matter occurs very rarely. However, synthetic yarns like polyester can have different fiber qualities with different glossiness. Mixed-up yarns can lead to defects in the following processes along the production chain. The visual inspection of these costly errors is still very time- and labor-intensive.

Indonesia-based textile company PT Superbtex has a simple and efficient solution to overcome this issue. It has installed the yarn clearer YarnMaster ZENIT+ with the OffColor feature. The new functionality has been developed for the detection and elimination of very small color and shade variations in mélange yarns..

Founded in 1974, PT operates four facilities and produces polyester yarns. The company is trying to improve processes along the value chain and in order to reach a better profitability the focus is on optimal quality and higher efficiency. The major portion of the production is delivered to the local market for both weaving and knitting applications, while some 15 per cent of the production is exported.

It uses different polyester fibers in its spinning mill. Dull, semi-dull, bright, and super-bright are the typical fiber qualities used and all of these have a different glossiness.
