The Kordárna Plus a.s., Chemical Fiber Plant Senica

Fiber production in Senica has almost a century-old tradition, started in 1921. Under the brand name Slovak Silk, company originally produced viscose textile fiber, which was interrupted by the Second World War. After recovery for decades the company played a very important role in textile industry producing viscose, later polyester yarns. Modern spinning lines were installed in 2012 and new production program has been launched. Chemical fiber plant manufactures man-made fibers based on PTA, with utilization for different applications of technical fabrics. The production assortment consists of two main types- high modulus low shrinkage and high tenacity yarn, with or without rubber adhesion activator. The production process is a combination of continuous and batch systems. The feedstock, PET granulate, is purchased externally, and subsequently treated by crystallization and post-condensation processes. The polymer thus treated enters the spinning, stretching and winding at a speed of 3500m/min or 6400m/min, according to the product type. The final product is a cross-winded coil with specified physical and mechanical properties.
