MPI JD500 Jigger Dyeing Machine
The MPI JD500 is a custom-built jigger dyeing machine manufactured and fabricated in Pakistan by Marjan Polymer Industries. It is engineered for open-width processing of woven fabric and can be configured for laboratory development, pilot work, sampling or wider production requirements.
Each machine is designed against the buyer’s fabric width, batch requirement, dyeing process, utilities and preferred level of automation. Working widths can be manufactured from approximately 250 mm (10 inches) up to 1,500 mm (1.5 metres). The selected working width is fixed during engineering and fabrication; the roller face and guide clearances are designed around the specified fabric width.
Custom Jigger Dyeing Machine Manufacturer in Pakistan
Marjan Polymer Industries supplies the JD500 as a build-to-order textile machine rather than a single fixed laboratory unit. This approach allows the mechanical construction, liquor trough, rollers, drive, heating arrangement, controls and material of construction to be matched to the actual application.
The machine is primarily intended for woven fabrics processed in open width. Typical operations can include pretreatment, scouring, bleaching, dyeing and washing, subject to the selected fabric, chemicals and machine configuration. Stretch fabrics, knitted fabrics and highly tension-sensitive materials require a technical suitability review before quotation because a jigger applies lengthwise tension during fabric transport.
How the JD500 Jigger Dyeing Machine Works
In a jigger process, the fabric is handled in open width and travels repeatedly between two main rollers. During each passage, the fabric moves through the process liquor held in the trough. The drive direction is reversed at the end of each pass so that the batch can be processed for the required number of cycles.
Controlling fabric speed, tension, process temperature, liquor condition and the number of passes helps the operator reproduce a defined dyeing or pretreatment procedure. The final control method depends on whether the machine is intended for laboratory trials, pilot-scale work or a wider production application.

Core Engineering Features
- Application-specific working width: Roller face length, guides and machine frame are engineered for the nominated fabric width and required operating clearance.
- Bidirectional fabric travel: Forward and reverse operation supports repeated fabric passes through the process bath.
- Variable-speed drive: The drive arrangement can be configured for controlled fabric transport and process development.
- Adjustable fabric tension: The selected tension-control method supports orderly batch build-up and stable fabric handling.
- Engineered liquor trough: Trough geometry and working liquor volume are sized for the specified fabric width, batch and process.
- Temperature monitoring and control: Sensor type, controller, heating capacity and protection are selected for the final design.
- Process observation: An inspection cover or viewing arrangement can be incorporated where required for safe visual monitoring.
- Drainage and cleaning: Drain, rinse and cleaning provisions are designed around the bath and circulation configuration.
- Electrical and process protection: Emergency stop, over-temperature protection and suitable electrical protection are incorporated according to the approved control scheme.
Available Customization Options
The following items are selected during technical discussion and are not represented as standard equipment on every machine:
- Required working width and roller face length
- Fabric length, batch weight and maximum roll diameter
- Roller diameter, surface finish and guide arrangement
- Liquor trough capacity and working liquor volume
- Heating method, installed heating load and temperature-control arrangement
- Cooling jacket or external cooling arrangement
- Liquor circulation, agitation or auxiliary mixing system
- Manual controls, digital controllers, VFD controls or PLC/HMI automation
- Inspection cover or viewing window
- Stainless-steel grade for wetted components and other selected parts
- Auxiliary fabric-handling or expander arrangement
- Floor-mounted frame, access provisions and site-specific utility connections
Final machine dimensions, weight, connected load, liquor volume, roller diameter, speed range and other numerical specifications are issued only after the application and configuration have been approved.
Laboratory, Pilot and Production Applications
A smaller JD500 configuration can support textile laboratories, universities, research centres, dye houses and product-development teams working on sample preparation, recipe development and process trials. A wider machine can be fabricated for full-width fabric when the required batch size, throughput and site services are defined.
Scale-up performance depends on more than machine width. Fabric construction, pretreatment condition, dye class, liquor ratio, circulation, temperature profile, tension, speed and number of passes must also be considered when translating a laboratory procedure to a wider machine.
Made-to-Order Supply from Marjan Polymer Industries
MPI manufactures and fabricates the JD500 in Pakistan. The commercial process begins with an application review so that the quotation reflects the machine the customer actually requires, rather than an inaccurate standard price or a generic specification.
Machine supply can include installation, commissioning, operator training and after-sales technical support. The JD500 is offered with a one-year limited company warranty, subject to the scope, exclusions and operating conditions stated in the final quotation and supply documents.

Frequently Asked Questions
Is the MPI JD500 manufactured in Pakistan?
Yes. Marjan Polymer Industries manufactures and fabricates the JD500 in Pakistan according to the approved technical requirement.
What working widths are available?
A JD500 can be manufactured from approximately 250 mm (10 inches) up to 1,500 mm (1.5 metres) working width. Each supplied machine is fabricated for its selected width. The roller face length includes the engineering clearance required for fabric edges and guides.
Is the JD500 only a laboratory jigger?
No. The JD500 is a configurable machine platform. It can be engineered as a compact laboratory or pilot machine, or as a wider machine for full-width fabric. Batch capacity, throughput and utilities must be defined separately.
Which fabrics can be processed?
The machine is primarily designed for woven fabric processed in open width. Suitability for knitted, stretch or particularly tension-sensitive material must be reviewed before the machine is specified.
What is the maximum operating temperature?
The maximum temperature depends on the approved machine design. Atmospheric configurations are generally engineered for operation up to approximately 98°C. MPI does not claim high-temperature or pressure operation unless that capability is specifically engineered and documented.
What is the JD500 jigger dyeing machine price in Pakistan?
There is no reliable universal price because working width, batch size, materials, heating, controls and auxiliary systems change the machine cost. MPI provides a project-specific quotation after reviewing the customer’s application.
Are installation and training included?
Installation, commissioning, operator training and after-sales support can be included in the commercial scope. The exact responsibilities of MPI and the customer are stated in the final quotation.
What warranty is provided?
The machine is supplied with a one-year limited company warranty. The final quotation and warranty document define covered items, exclusions and operating conditions.
