Several Commonly Used Dyeing Equipment

In the process of dyeing, it is necessary to improve the labour productivity and obtain a smooth and firm color without damaging the fibers.

According to different products and different dyes, reasonable selection and formulation of dyeing process, the dyeing equipment must comply with the process requirements.

There are many kinds of dyeing machines, which can be divided into batch dyeing machine and continuous dyeing machine according to the operation characteristics of the machine. According to the dyeing method, they can be divided into dyeing machine, dyeing machine and pad dyeing machine. According to the dyeing state, they can be divided into bulk dyeing machine, yarn dyeing machine and fabric dyeing machine.

Reasonable selection of dyeing machinery and equipment plays an important role in improving product quality, reducing production costs and improving production efficiency.

Continuous rail dyeing machine

Continuous pad dyeing machine is suitable for large-scale continuous printing and dyeing. It is made of cotton, chemical fiber and its mixture.

The most important dyeing equipment.

According to the dyestuffs used, the type of continuous pad dyeing machine is different, but their composition can be roughly divided into the following parts:

1. rolling stock: the main device for fabric dyed and dyed.

2. drying equipment: including infrared, hot air and drying oven three kinds.

3. steamer: some dyestuffs should be steamed after dyeing, and saturated vapor is added into the steamer to expand the fibers and dye and other chemicals into the fiber.

4. flat washing device: it includes multi grid flushing tank, which can be used for cold water, hot water, soap boiling and post-treatment according to different dyes.

5. drying device after dyeing: drying after dyeing is done by drying oven.

Two. Dyeing machine

The jigger is a batch dyeing machine. According to its working nature, it can be divided into ordinary dyeing machine, high temperature and high pressure dyeing machine.

When dyeing, the fabric is retreated from the passive roll roller into the slot and then wound onto the active cloth roller.

When the fabric is rolled together, it changes to another shaft, and the shaft changes.

Dye the finished fabric and roll it out of the cylinder.

The disadvantage of common dyeing machine is that the speed of the fabric is inconsistent, the tension is large, and the labor intensity is large.

The equal speed dyeing machine and automatic dyeing machine can overcome these shortcomings. The automatic dyeing machine can also adjust direction, record number and stop automation.

Three. Overflow and jet dyeing machine.

(1) overflow dyeing machine: overflow dyeing machine is a special form of rope.

。

Because the fabric is relaxed during dyeing, the tension is small, and the dyed fabric is soft and uniform. Therefore, it is used for dyeing of synthetic fabric, warp knitted fabric and elastic fabric under high pressure.

In recent years, some atmospheric overflow dyeing machines have been made, which can be used for dyeing natural fiber fabrics under atmospheric pressure.

The machine is easy to operate and easy to use, but the bath ratio is high when dyeing, and the dye and water consumption are large.

(two) jet dyeing machine: the jet dyeing machine occupies a small area with high output and saves material, power and labor.

It is not only high temperature and high pressure, but also atmospheric pressure. It can be used not only for synthetic fibers but also for natural fibers. It can be used not only for dyeing but also for processing before and after treatment.

Because of its versatility, it is more welcomed by manufacturers.

The jet action of the dye helps to dye the dye into the rope like fabric, and the dye bath ratio is also smaller, and the tension of the fabric is smaller, so that the dyeing effect is better than that of the overflow dyeing machine.

(two) jet skein dyeing machine: it consists of dyeing tank, hole tube, rotary device and pump.

When dyeing, the twisted yarn is respectively sleeved on a flat hole tube, and the dye solution is sent into the hole from the liquid tank by the pump and sprinkled on the twisted yarn.

At the same time, due to the rotation of the rotary device, the twisted yarn sleeved on the hole tube will gradually rotate to achieve uniform dyeing. This equipment is relatively small in bath, and the loading and unloading operation of the skein yarn is convenient. However, the cleaning is often needed to prevent clogging.
