Jigger Dyeing

NSWR Series Sample Jigger

A small-scale standard dyeing jigger for laboratory and sample dyeing.

Features:

1. AC frequency-conversion drive; single or double frequency conversion available on request.

2. Touch screen or text display operation according to user requirements.

3. Automatic temperature control, automatic pass counting, automatic reversing, automatic stop and cloth spreading.

4. Dyeing programs can be set as required; multiple jiggers can be centrally controlled.

5. Pneumatic door opening and closing with a sealing strip fitted on the door.

6. Optional cloth discharge unit, circulation unit and other auxiliary configurations on request.

Constant tension: the tension on the fabric can be adjusted freely and held uniformly throughout the process. Dyeing of tension-sensitive fabrics with almost no tension gives good results.

Constant fabric speed: works at a constant speed under program control, minimizing shade variation of the dyed fabric for a better dyeing result.

WHERE IT IS USED

Sample dyeing: before and after

Applications

Before and after dyeing: undyed white fabric on the left, the same fabric dyed one even red on the right — Left: before. Right: after. Illustration.

Before: Undyed white cloth.
After: The whole piece takes one even colour from edge to edge.
Typical use: Sample lengths are dyed to the target shade first, so the colour is agreed before the bulk lot runs.

WHERE IT ENDS UP

Final products

Applications

Colours agreed on sample lengths here carry over to bedding, curtain, sofa and workwear cloth.

What a sample jigger is used for

The NSWR sample jigger is a small standard jigger for laboratory dyeing and sample dyeing. It lets a dye house match colour and test a recipe on a few metres of the real fabric before a bulk lot.

It runs the same method as a production jigger: open-width cloth wound between two rolls through a small bath. That makes sample results transfer well to jigger production.

Runda lists touch screen or text display, automatic temperature control, pass counting, reversing and stop, and a pneumatic door with a sealing strip.

Selection points for the NSWR sample jigger

Scale-up. The sample jigger helps most if your production machine is a jigger too. Process settings carry across with the same tension and speed logic.

Operation. Choose touch screen or text display. A touch screen helps if you store many recipes.

Drive. Single or double frequency conversion is available. Double gives separate roll control, closer to a large jigger.

Central control. If you run several machines, ask about connecting them to one controller.

Accessories. Optional cloth discharge and circulation units are available on request.

Typical applications of the NSWR Sample Jigger

Colour matching before a bulk jigger lot
Recipe tests for reactive, direct, vat and disperse dyes
Small sample orders before a bulk lot
Training of dye-house staff

Configuration options

Double frequency conversion (optional, on request)
Cloth discharge unit (optional)
Circulation unit (optional)
Central control of several jiggers (optional)

Items marked optional are available on request. The final configuration is confirmed on the quotation.

NSWR Sample Jigger: frequently asked questions

Why use a sample jigger rather than a beaker dyer?

Beaker dyers use cut swatches in small pots. A sample jigger dyes a length of cloth under real tension and speed, which is closer to jigger production.
