When Do You Need a Sample Jigger or Laboratory Jigger?
A sample jigger dyeing machine reproduces the open-width jig principle on a small scale: fabric travels back and forth between two rollers through a small dye bath, exactly as it does on production jiggers. That means lab samples correlate far better with bulk open-width batches than small beaker trials do.
It is the right textile sample dyeing jigger for dyeing-house labs doing color matching, for trading houses and brands approving shades, for mills developing new recipes, and for small-batch dye houses running low-volume lots.
Because constant tension and constant fabric speed are held on the small machine, tension-sensitive fabrics can be sampled with almost no tension - which protects delicate goods and keeps lab-to-bulk shade transfer honest.
Core Parameters & Technical Data
Type: small-scale standard dyeing jigger for laboratory and sample dyeing.
Drive: AC frequency-conversion drive; single or double frequency conversion available on request.
Operation: touch screen or text display, according to user requirements.
Automation: automatic temperature control, automatic pass counting, automatic reversing, automatic stop and cloth spreading.
Programmability: dyeing programs can be set as required, and multiple jiggers can be centrally controlled.
Door: pneumatic door opening and closing, with a sealing strip fitted on the door for a tight, safe operation.
Options: cloth discharge unit, circulation unit and other auxiliary configurations on request.
Control quality: constant tension is freely adjustable and held uniformly throughout the process; constant fabric speed works under program control, minimizing shade variation of the dyed fabric.
How to Choose the Right Laboratory Jigger
Match the scale to your work. This is a lab jigger for fabric dyeing and color matching, not a production batch machine - if your lots are truly small production runs, ask us about our production jigger series.
Choose touch screen or text display by your operators' habits. Touch screens suit program-heavy labs; text display is the simpler, lower-cost option.
Decide single versus double frequency conversion. The double inverter option controls the drives more independently for tighter tension control on delicate samples.
Check program memory and central control. If several jiggers share one lab, central control and settable dyeing programs standardize recipes across machines.
Plan the auxiliaries you will actually use: cloth discharge unit and circulation unit are ordered on request, so decide before purchase rather than after.
Buy from a factory that also builds production jiggers. Then the sample machine's process logic matches your bulk machines, and lab settings transfer straight to production.
Common Mistakes Buyers Make
Approving shades on lab beakers for jig production. Open-width samples run on a real sample jigger transfer much better to bulk jig batches.
Under-specifying control. Without automatic temperature control, pass counting and program memory, sample recipes drift and lab-to-bulk correlation suffers.
Ignoring tension control. Tension-sensitive fabrics sampled under the wrong tension come out with a different shade and handle than they will in bulk.
Forgetting auxiliary options. Cloth discharge and circulation units are on-request items - plan them at order time, not after the machine arrives.
Buying a sample machine from a seller with no production line. Then there is no production jig to correlate the samples with, which defeats the purpose.
Why Buy from Wuxi Runda
We are a production factory founded in 2004, located in Qianzhou, Wuxi - inside Jiangsu's dyeing machinery industrial cluster, close to component supply and an experienced skilled workforce.
We cooperate with textile research institutes and technical colleges year-round on dyeing and finishing equipment and processes, and design and develop our own jigger series after absorbing the advantages of jiggers from Japan, Denmark and Italy.
Our sample jigger keeps the same constant-tension, constant-speed control philosophy as our production jiggers, built for small batches, multiple varieties and low energy consumption.
Our equipment is exported to Vietnam, India, Bangladesh, Indonesia, Pakistan, Japan, Thailand and other Southeast Asian markets, with complete after-sales service including installation, commissioning, spare parts and operator training.
Frequently Asked Questions
What is a sample jigger dyeing machine used for?
It is a small-scale standard laboratory jigger for sample dyeing and color matching: it reproduces open-width jig dyeing on a small scale, so lab samples correlate well with bulk production batches.
Can the sample jiggers be controlled centrally?
Yes. Dyeing programs can be set as required, and multiple jiggers can be centrally controlled - useful when one lab runs several sample machines.
What automation does it have?
Automatic temperature control, automatic pass counting, automatic reversing, automatic stop and cloth spreading, with touch screen or text display operation per your requirement.
Is double frequency conversion available?
The drive is AC frequency-conversion, and single or double frequency conversion is available on request. The double inverter option gives tighter tension and speed control.
Can it run small production batches?
It is designed for laboratory and sample dyeing. If you need true small-lot production, tell us your fabric and lot size - our production jigger series will be the right match.
