When Do You Need an HTHP Jigger Dyeing Machine?
A high-temperature high-pressure jigger dyeing machine dyes open-width woven fabric inside a sealed chamber at raised temperature and pressure, which is required when disperse dyes must fix on polyester and other synthetics above 100 degC.
The GR680-1200 suits various synthetic, cotton and linen fabrics and carries out dyeing with disperse, sulfur, vat, direct and reactive dyes, as well as scouring, soaping and washing - all at constant speed and constant tension.
It is the choice for dyehouses that want open-width, low-tension dyeing on synthetics rather than rope-form jet dyeing. The 1200 mm maximum fabric roll diameter is the larger-roll variant of the GR680 HTHP jigger family, for longer batches on wider fabric. For dyehouses growing batch lengths, this larger roll means fewer batch splits and less set-up time per order.

Process: constant speed and constant tension throughout the batch.
Main roller diameter: 220-325 mm.
Max fabric roll diameter: 680-1200 mm - the larger-roll configuration of the GR680 family.
Max fabric width: 1600-3400 mm.
Adjustable fabric tension: 0-90 kg.
Adjustable fabric speed: 0-130 m/min.
How to Choose an HTHP Automatic Jigger
Start with the fabric. If you dye polyester, nylon or other synthetics, you need a pressurized HTHP jigger; cotton, linen and viscose can run on an atmospheric jigger at lower cost.
Choose the roll diameter against batch length. The GR680-1200 takes a maximum fabric roll diameter of 680-1200 mm, so it suits longer open-width batches; the smaller-roll GR680 configuration suits shorter, entry-level lots.
Match max fabric width to your widest cloth, with margin - the 1600-3400 mm range covers most weaving plants.
Use the tension range for your fabric. The 0-90 kg adjustable tension lets you run tension-sensitive woven goods gently and heavy fabric firmly.
Check automation for repeatability. An automatic HTHP jigger keeps reversing, counting and temperature consistent batch to batch, which is what gives level shades on synthetics.
Confirm the dye classes you will run. The machine covers disperse, sulfur, vat, direct and reactive dyes, so plan around your real color range.
Common Mistakes Buyers Make
Buying an atmospheric jigger for polyester. Synthetics need the pressurized, above-100 degC environment; an atmospheric jig dyeing machine cannot fix disperse dyes reliably.
Under-sizing the roll diameter for batch length. A small-roll jigger means more batch splits and more set-up time; choose the 680-1200 mm roll for the long batches you actually run.
Ignoring tension control on delicate woven fabric. Without adjustable, constant tension, sensitive cloth creases and stretches - the 0-90 kg range must be used, not left at a fixed setting.
Mismatching width to fabric. A machine too narrow cannot be widened later; measure your real widest fabric and add allowance.
Buying without after-sales support. A pressurized jigger needs commissioning, sealing checks and parts - a direct production factory keeps it running.

Frequently Asked Questions
What is the maximum fabric roll diameter of the GR680-1200?
The GR680-1200 series takes a maximum fabric roll diameter of 680-1200 mm, with a main roller diameter of 220-325 mm. It is the larger-roll HTHP jigger in the GR680 family for longer open-width batches.
What fabric width and speed can it handle?
Maximum fabric width is 1600-3400 mm, adjustable fabric speed is 0-130 m/min, and adjustable fabric tension is 0-90 kg. Tell us your fabric width and batch length and we will confirm the configuration.
Can this jigger dye polyester fabric?
Yes. As a high-temperature high-pressure jigger, it is designed for synthetic fabrics and runs disperse dyes, alongside sulfur, vat, direct and reactive dyes, plus scouring, soaping and washing.
What is the difference between the GR680-1200 and smaller GR680 jiggers?
Both are GR680-family pressurized automatic jiggers for synthetics and cotton/linen. The GR680-1200 is the larger-roll configuration for longer batches; choose by your target fabric roll diameter and batch length.
What dyes and processes can it run?
Dyeing with disperse, sulfur, vat, direct and reactive dyes, as well as scouring, soaping and washing, all carried out at constant speed and constant tension.
