What the GR680-1000 HTHP jigger is built for
The GR680-1000 is a high-temperature high-pressure automatic jigger from the GR680 series. The closed vessel allows dyeing above 100 °C, so polyester can be dyed with disperse dye in an open-width, low-tension process.
Runda lists synthetic, cotton and linen fabrics with disperse, sulfur, vat, direct and reactive dyes. Scouring, soaping and washing run at constant speed and tension.
Published roll diameter is given as 680, 1,000 to 1,200 mm. The GR680-1200 is the other model in the series.
