TO meet increasing demand for smaller batches Thies Textilmaschinen has introduced a new atmospheric NT-Jigger suitable for dye lots from 1,000 m at an operating temperature of 98ºC.The new NT-Jigger is ideal for the dyeing of woven and open width knit fabrics. It is especially recommended for the treatment of crease sensitive, permeable and non-permeable fabrics in open-width form, offering optimum flexibility for the finishing of natural fibres.
An integrated fabric transfer system with a new spreader system for crease-free loading/unloading of the fabric is also available. At the same time it avoids selvedge curl on fabrics with up to 40% Lycra.
The NT-Jigger incorporates innovation in stepless tension and material speed. It also features an economical dye trough designed for uniform dyeing in short liquor ratio conditions.
A contrast liquor ratio from 55 - 100% of the fabric width is guaranteed with the new NT-Jigger. It also features a variable fabric tension of 10 - 100 kg at speeds of 10 - 150 m/min for fabric widths of up to 5.4 m. A choice of batch diameters of 1,000, 1,230 and 1,450 mm are also available.An industrial PC and rope monitoring system provides precise calculation and control of the fabric speed and tension maintaining optimum processing conditions throughout dyeing cycles. The jigger also offers direct drive of the main rollers via frequency controlled three-phase motors to ensure energy savings with brake drive current return.
A centre driven frequency controlled motor drive is also optionally available for loading/unloading operations. ‘Salt dissolving’ with an electric stirrer and automatic brine transfer into the kier are also available with the new jigger.
Other optional features include a water metre for controlled rinsing, a liquor filter and a floor level track system for the kier opening/closing.
