Thies hankMaster dyeing machine for specialty and premium yarns
According to the company, the stainless-steel machine features a specially designed liquor
flow that ensures perfect dyeing for hanked yarns such as wool and soft and mercerized cotton; and
fibers including polyamide, silk, viscose and high-bulk acrylics. Dye temperatures range up to 98°C
at starting liquor ratios as low as 1:5 depending on loading and yarn capacity. Hanks measuring up
to 950 millimeters (mm) in length are rotated on specially designed, 960-mm-long rods that hold up
to 10 kilograms of yarn, eliminating high spots and luster marks; and the machine can be equipped
with two, four, six, eight or 10 rods. Other features include a centrifugal circulation pump;
cartridge heat exchanger; and industrial computer control and monitoring of dyeing and finishing
processes. Automatic dye and chemical dosing using pre-programmed times and curves is available
with analog dosing.
