The Most Valuable Guide to Jigger Dyeing Machine Selection-1

According to the dyeing method, dyeing machines can be categorized into three groups: dip dyeing machines, jigger dyeing machines, and pad dyeing machines. Additionally, it can be divided into categories based on whether the dyeing process is continuous or intermittent and if the dyeing machine operates at atmospheric pressure or high pressure.

​The jigger dyeing machine is the focus of this article among the several forms of dyeing equipment. It primarily introduces classification and development, technical features of domestic and foreign brands, and the best options for jigger dyeing machine.

​Definition, classification and development of jigger dyeing machine

Definition and history

​Jigger dyeing machine was initially constructed out of wood or iron as an open-width dyeing tool. It significantly increased fabric dyeing efficiency over the manual workshop-style operation used at the time and decreased labor intensity and dyeing time. In the late 1970s, the machine  constructed of stainless steel increasingly started to appear.
Jigger dyeing machine can be used to dye fabrics with sulfur, vat, reactive, and direct dyes. Additionally, desizing, scouring, bleaching, washing, and post-treatment are all possible uses for it. It is particularly suited for multi-variety and small batch processing and production because to its straightforward structure, flexible operation, convenient maintenance, low investment cost, and wide range of uses.
Because they support the growing trend of small batch and multi-variety dyeing, jigger dyeing machines are still commonly employed nowadays. But after numerous upgrades, the level of equipment has significantly changed. In the middle and late 20th century, France, Germany, Italy, and other developed nations in Europe started to research the automation of the printing and dyeing business.

Their dyeing and finishing machinery is extremely intelligent, especially in the high-precision transmission system, information-based control system, and unconventional management system. In order to achieve the functions of real-time monitoring, intelligent control, and closed-loop feedback adjustment of the jigger dyeing process, the majority of them utilize electronic information technology, frequency conversion speed regulation technology, and sensor detection technology. A worker can monitor several devices simultaneously when combined with the field bus arrangement, exhibiting the features of high efficiency, economy, energy conservation, etc. in line with the advancement of the times.

Classification

Jigger dyeing machines can be categorized using a variety of criteria, including the material of the dye tank, the way they are used, the width of the fabric, the position of the reel, the speed or tension of the fabric line, the temperature and pressure at which they are used, etc. The machines are typically categorized according on their operating pressure and temperature.

Development

​The normal temperature jigger can be classified into several distinct types depending on the transmission mode, including friction wheel, hydrodynamic gravity, epicyclic gear, electric differential, and ordinary types. Based on the printing and dyeing factory’s productionh practice.

• The fabric line speed and consistent tension are poorly stabilized by the mechanical differential speed regulator dye vat.
• Despite the fact that DC motors have a lot of beginning torque and a wide speed regulation range, However, when jigging in a climate with high temperatures and humidity, it is simple to burn the windings, and DC motor maintenance is quite inconvenient.
• Better speed and tension consistency of the fabric line is provided by the hydraulic transmission mode. The hydraulic station, however, is difficult to maintain and prone to issues like heat generation and oil leakage.

Additionally, the penetration efficiency of the traditional jigger is poor, it is primarily used for dipping clothes in dye liquid, and some thick and dense materials are susceptible to the “white core” phenomena. As a result, both domestic and international producers have incorporated numerous new technologies to enhance conventional jiggers. like:
The speed measuring system realizes the constant line speed jigging of the fabric and realizes the automatic control of the jigging process, reducing the need for labor, by using the three-phase AC servo motor to drive the cloth roll through the reduction.
The quality and efficiency of dyeing, as well as the pretreatment and washing of cotton and linen fabrics, are increased by the improvement of the uniformity of a pair of rolling mills.
Jigger dyeing machine is the main piece of machinery used in short-process processing. As can be seen, this dyeing procedure uses relatively little energy for the steam, water, power, and dying materials.
In recent years, a high temperature and high pressure jigger dyeing machine that can process polyester fabrics has been successfully developed in order to adapt to the dyeing and finishing of polyester fabrics. The pad roller dyeing tank is now outfitted with a sealable stainless steel tank.
The specific ways of improvement include the following features in addition to the enhancement of constant tension and constant speed:

1. Control system with steady speed and tension
2. Measures to lower the liquor ratio
3. Measures to make rolling liquid more permeable
4. Adding an automatic device
5. Include a capping mechanism with a high temperature and high pressure.
