Fabric dyeing machine - Beam dyeing

Fabric dyeing machine 

There are certain types of machines that are used for the fabric dyeing process.

1. Jigger dyeing machine
2. High-temperature jigger dyeing machine
3. HT vacuum jigger dyeing machine
4. Winch dyeing machine
5. High-temperature beam dyeing machine
6. Pad dyeing machine
7. Jet dyeing machine
8. Soft overflow jet dyeing machine  

High-Temperature High-pressure beam dyeing machine

A single, big-diameter beam that may be put into the autoclave of the beam dyeing machine is often dyed. 

A perforated beam that has been coiled with the fabric to be dyed is then moved into a pressure vessel. 

The machine is provided with an inside-out and outside-in reversible flow system. the bulk of the time, the material is dyed from the within out because outside-in flow puts the material in danger of slipping off the perforated beam. 

However, with some tightly woven fabrics, outside-in flow is also required. With the help of a strong pump, the dye liquid is driven through the material tied around the beam. 

The figure below depicts the key components of the standard beam dyeing system.

The temperature of the dye fluid is automatically maintained at any desired level with a tolerance of 1 degree Centigrade because it runs through a device during a closed system. 

At a continuing, previously determined pressure, the dye fluid is pumped through the material. counting on the sort of cloth being dyed, the pressure and liquid flow will be changed. 

The machine incorporates a flow control valve that closes when the liquor circulation pump isn't functioning. 

The valve slowly opens when the flow is reversed, preventing a quick buildup of alcohol pressure that would damage the material layers. 

While the machine is fraught, a selected sampling tool is on the market to get rid of the sample for matching. 

Genuinely, the samples don't seem to be collected from the batch directly but rather from fabric that's constantly to bear with the flowing alcohol. 

Automatic temperature control systems are present in modern HT beam dyeing machines. With the employment of an electronic programme controller, the dyeing cycle will be modified. Adding chemicals and dyestuffs is feasible while dyeing.

Batching

When employing warm-temperature beam dyeing equipment, winding the products onto a perforated beam is crucial. 

To confirm homogeneous batching of materials with moderate tension, it's advisable to utilise specially designed batching devices. Neither too tight nor too loose batching is suitable. 

Loosely woven lapping fabric is first wont to cover the beam. to forestall slippage of the fabric being dyed and stop perforation marks, 8 to 10 layers of such cloth are sufficient. 

The material's length should extend past the holes within the beam, which is another crucial consideration during batching.

The majority of the time, alcohol will choose the simplest route. to forestall this, it must be made sure that the resistance is as equal as possible throughout the material roll, including the sides. 

Therefore, there must be a greater amount of overlap beyond the perforation. The roll's thickness directly relates to how dense the fabric is. it's important to recollect that the selvedges are extremely dense in this area. 

Too little overlap leads to an excess flow of the dye liquor toward the material's outermost corner, which causes the material to become darker there. the alternative is additionally true. 

The standard and density of the material, furthermore because of the roll's thickness, determine what proportion the selvedges should overlap. for example, with weave, even for a rather thick roll, an overlap of 3-5 cm is usually sufficient.

This type of machine is available with a design based on the latest dyeing know-how and unique technology regarding the optimised distribution of flow circulation. energy savings, etc.
