When Do You Need a Propelled (Propeller) Jigger Dyeing Machine?
A propelled (propeller) jigger is a pressurized open-width jig dyeing machine in which the fabric is moved under controlled, adjustable tension. The NGR Series is mainly used for dyeing cotton, acrylic, polyester/cotton, polyester, silk and spandex fabrics.
It is built to prevent dye stains on the fiber to the greatest extent, has no heat loss and saves energy, and is especially suitable for extra-wide fabrics. The constant-tension design lets tension-sensitive fabrics be dyed at almost no tension for outstanding results.
If your goods are wide, delicate or prone to staining, and you want open-width HTHP dyeing rather than rope-form jet dyeing, this pressurized jigger is the machine that protects the fabric while reaching the temperature synthetics require.
Core Parameters & Technical Data
Fabrics: cotton, acrylic, polyester/cotton, polyester, silk and spandex fabrics.
Constant tension: fabric tension is adjustable freely and held uniformly through the process; tension-sensitive fabrics can be dyed at almost no tension.
Constant fabric speed: runs at a constant speed under program control, minimizing shade variation.
Automation: the whole dyeing process uses a standard automatic system, reducing labor cost.
Construction: domestic low-alloy steel plate, quality stainless steel plate and high-grade electrical components; simple, easy to repair and operable by ordinary workers.
Max fabric working diameter: 800-1200 mm.
Max fabric working width: 1800-3200 mm.
Main roller diameter: 245-325 mm.
Working temperature: 140 degC; max working pressure: 2.75x10^5 Pa.
Liquor ratio: 1:3 - a very low ratio that saves water, steam and dyestuff.
Fabric speed: 20-100 m/min; fabric tension range: 5-80 kg/m; motor power: 3-10 kW.
How to Choose a Propeller Jigger
Define width first. The NGR Series is especially for extra-wide fabric, with a max working width of 1800-3200 mm - confirm your widest cloth before ordering.
Match tension to fabric. The 5-80 kg/m adjustable range lets you run silk, spandex and other tension-sensitive goods at near-zero tension, and heavier woven fabrics firmly.
Value the low liquor ratio. A 1:3 ratio cuts water, steam and chemical use per batch - a direct energy and cost saving for regular production.
Check the temperature range. At a 140 degC working temperature and pressurized chamber, the machine covers synthetics that need heat above 100 degC.
Weigh maintenance. The simple construction is easy to repair and operable by ordinary workers, which lowers running and training costs.
Compare roll diameter to batch length. The 800-1200 mm fabric working diameter suits longer extra-wide batches - plan your roll against your lot size.
Common Mistakes Buyers Make
Using a narrow jigger for extra-wide fabric. Wide goods need the 1800-3200 mm working width; forcing them through a narrow machine causes edge damage and wasted cloth.
Running tension-sensitive fabric at fixed tension. Silk, spandex and blends must use the adjustable, near-zero constant tension - a fixed setting stretches or creases them.
Overlooking the low liquor ratio. A 1:3 ratio is a major water and steam saving; buyers who ignore it may pay far more in running costs than the machine price difference.
Expecting rope-jet behaviour from an open-width jigger. The NGR dyes open-width; if you need very large rope lots, an overflow jet machine may suit better.
Buying without parts and training. The machine is simple, but commissioning and operator training still come from a production factory with a service network.
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 skilled workers.
We cooperate with textile research institutes and technical colleges year-round, and our jiggers absorb the advantages of jiggers from Japan, Denmark and Italy, designed and developed by ourselves.
We build jiggers for small batches, multiple varieties and low energy consumption; the NGR Series saves energy with no heat loss and a 1:3 liquor ratio.
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 propeller (propelled) jigger dyeing machine?
It is a pressurized open-width jig dyeing machine that moves fabric under controlled adjustable tension. Runda calls it a propeller jigger; English catalogues often write propelled jigger. The NGR Series is built for extra-wide, tension-sensitive fabrics.
What fabrics can the NGR propeller jigger dye?
Mainly cotton, acrylic, polyester/cotton, polyester, silk and spandex fabrics. Its constant-tension design is especially good for tension-sensitive goods and for preventing dye stains.
What is the working temperature and liquor ratio?
Working temperature is 140 degC with a max working pressure of 2.75x10^5 Pa, and the liquor ratio is 1:3 - a very low ratio that saves water, steam and dyestuff per batch.
How wide and how long a batch can it handle?
Max fabric working width is 1800-3200 mm, max fabric working diameter is 800-1200 mm, fabric speed is 20-100 m/min and tension range is 5-80 kg/m. Tell us your fabric width and lot size and we will confirm the model.
Why is the NGR jigger good for extra-wide fabric?
Its 1800-3200 mm working width, near-zero constant tension and low 1:3 liquor ratio are all designed for wide woven goods, preventing creasing, stretching and dye stains while saving energy.
