When Do You Need an HTHP Jigger Dyeing Machine?
A high-temperature high-pressure jigger dyeing machine runs fabric in a sealed chamber above 100 degC under pressure, which is the only reliable way to fix disperse dyes on polyester. You need this class of machine when your goods are synthetic - polyester, polyester blends and similar synthetics - that an atmospheric jigger cannot dye level.
The GR680-1000 suits various synthetic, cotton and linen fabrics and carries out dyeing with disperse, sulfur, vat, direct and reactive dyes, plus scouring, soaping and washing at constant speed and constant tension. It is the compact, entry-size member of our GR680 HTHP jigger family.
If your dyehouse is moving into woven polyester or needs a pressurized jig dyeing machine for smaller batches, the 680-1000 model is the natural starting point; the wider GR680-1200 covers larger roll and width requirements.

Main roller diameter: 220-325 mm.
Maximum fabric roll diameter: 680-1000-1200 mm across the GR680 series.
Maximum fabric width: 1600-3400 mm.
Adjustable fabric tension: 0-90 kg.
Adjustable fabric speed: 0-130 m/min.
Processes: dyeing with disperse, sulfur, vat, direct and reactive dyes, plus scouring, soaping and washing, all at constant speed and constant tension.
How to Choose the Right HTHP Jigger
Start with temperature and pressure. Synthetic fabrics - especially polyester - demand an HTHP jigger; do not try to dye disperse shades on an atmospheric machine.
Size the roll and width to your fabric. The 680-1000 is the compact HTHP entry; if you run very wide or very heavy rolls, step up to the wider GR680-1200 series.
Check tension and speed ranges. Adjustable tension 0-90 kg and speed 0-130 m/min cover fine to heavier woven goods; match them to your most sensitive fabric.
Confirm the dye classes and after-processes you need. The machine runs disperse, sulfur, vat, direct and reactive dyes and also scouring, soaping and washing in the same unit.
Look for constant speed and constant tension control - they are what keep disperse shades level across repeated pressurized cycles.
Choose a production factory that can commission a pressure vessel correctly; safe operation of an HTHP chamber depends on proper installation and training.
Common Mistakes Buyers Make
Buying an atmospheric jigger for polyester. Above 100 degC pressure is mandatory; an open machine will not fix disperse dyes.
Confusing the two GR680 sizes. The 680-1000 is the compact entry; ordering it for very wide or heavy rolls leaves you under-sized, while buying the 1200 model for narrow goods wastes investment.
Ignoring the tension range. Too much tension on delicate woven polyester causes creasing and wrinkles that survive finishing.
Skipping soaping and washing in-spec. Disperse dyeing leaves unfixed dye; the machine must also handle soaping and washing, not just dyeing.
Treating it like a rope jet. An HTHP jigger dyes open-width - ideal for flat woven goods; if your fabric is knit or rope-form, an overflow dyeing machine may fit better.

Frequently Asked Questions
Can the GR680-1000 dye polyester fabric?
Yes. As a high-temperature high-pressure jigger, it is designed for disperse dyeing of polyester and other synthetics, and also suits cotton and linen fabrics, plus scouring, soaping and washing.
What is the difference between the GR680-1000 and GR680-1200?
Both are HTHP automatic jiggers in the same GR680 family. The 680-1000 is the compact entry-size model; the 680-1200 is the wider, larger-roll version for heavier or wider fabric. Tell us your fabric width and roll weight and we will match the right size.
What speed and tension ranges does it offer?
Adjustable fabric tension is 0-90 kg and adjustable fabric speed is 0-130 m/min, with main roller diameter 220-325 mm and maximum fabric width 1600-3400 mm.
Can it also soap and wash after dyeing?
Yes. The machine carries out dyeing together with scouring, soaping and washing at constant speed and constant tension, which is essential to remove unfixed disperse dye.
Is it suitable for small-batch polyester dyeing?
Yes. As the compact, entry-size HTHP model it fits dyehouses moving into polyester or running small, frequent synthetic lots, and our machines are built for small batches and low energy consumption.
