Iwanowo/Russia – The proposed facilities in Russia’s Ivanovo region shall become the centerpiece of a production complex for staple fibres, the company explains. Uhde Inventa-Fischer will provide the design of a 180.000 tons/year polycondensation plant together with its Russian sister company OOO Uhde for Ivregionsynthes.

The plant will be based on the company’s proprietary 2R polyester technology, which comprises the patented Espree and Discage reactors and enables the production of superior high-quality polyester polymer. A characteristic feature of the plant is that the polymer melt will be conveyed directly from the polycondensation plant to several downstream spinning lines where staple fibers will be produced. Designed for integration of Uhde Inventa-Fischer’s Flakes-To-Resin (FTR) recycling technology, the facility will be able to use up to 50% recycling material without adversely affecting the product quality, speakers explained.

Successful Start–Up of Chinese Polyamide 6 Production

Only recently, the company had commissioned a plant for the production of high-performance polyamide 6 for textile grade applications. The facility in the Economic Technical Development Area of Hangzhou City in Zhejiang Province, PR China, uses Uhde Inventa-Fischer’s Virgin Lactam Process (VLP) and High-Performance Polyamide 6 Additives (HPPA) to produce 47,000 tonnes per year of semi-dull chips.

Uhde Inventa-Fischer’s scope of supplies included the know-how license, formulae for the high-performance additives, basic engineering and supervision of the detail engineering, supply of all key equipment, supervision of erection and management of plant commissioning. In addition, the customer’s operating personnel was trained by experienced Uhde Inventa-Fischer specialists.

The polymerization reaction is performed in an advanced proprietary single-stage VK tube with a nominal capacity of 130 tonnes per day. This technology has been developed to produce a high-performance textile polymer which is highly homogenous.
