What are the different types of fabric dyeing machines?

1. Classification by dyeing method
Immersion dyeing machine
Working principle: The fabric is completely immersed in the dye solution, and the dye is gradually penetrated into the fabric fiber through the circulation and temperature control of the dye solution.
Features: It is suitable for dyeing various fabrics, especially for small batches and multi-variety fabrics. It has good dyeing uniformity, but the dyeing time is relatively long and the bath ratio is large.
Padding dyeing machine
Working principle: First, the fabric is dipped into the dye solution through a roller, so that the dye solution is evenly attached to the fabric, and then the dye is fixed in the fabric fiber by drying, steaming, etc.
Features: Fast dyeing speed, high production efficiency, small bath ratio, suitable for mass production. However, it has high requirements for the flatness of the fabric, and uneven dyeing is prone to occur.
Jet dyeing machine
Working principle: Use the powerful water jet effect to make the fabric roll and circulate continuously in the dye solution to accelerate the penetration and diffusion of the dye.
Features: Good dyeing uniformity, suitable for various fabrics, especially thin and soft fabrics. The production efficiency is high, but the equipment cost is relatively high.
2. Classification by equipment structure
Jigger dyeing machine
Working principle: The fabric is wound on the roller and dyed by continuously immersing and withdrawing the dye.
Features: It is suitable for continuous dyeing of long fabrics, with simple equipment structure, small footprint and easy operation. However, the dyeing uniformity is relatively poor, and there are certain restrictions on the width and thickness of the fabric.
Rope dyeing machine
Working principle: The fabric is circulated in the dye liquid in a rope form and dyed by the penetration and diffusion of the dye liquid.
Features: It is suitable for some fabrics that are easy to deform, such as knitwear. The tension of the fabric is small during the dyeing process, and it is not easy to produce wrinkles and deformation. However, the dyeing time is long and the production efficiency is low.
Overflow dyeing machine
Working principle: The dye liquid overflows continuously in the dye tank, and the fabric moves slowly under the drive of the dye liquid, and is dyed by the circulation of the dye liquid and temperature control.
Features: Good dyeing uniformity, little damage to the fabric, suitable for dyeing of various fabrics. However, the equipment occupies a large area and the dyeing time is relatively long.
3. Classification by applicable fabrics
Cotton fabric dyeing machine
Features: According to the characteristics of cotton fabrics, lower dyeing temperature and longer dyeing time are usually used to ensure that the dye fully penetrates into the cotton fiber. The dye liquor circulation system and temperature control system of the equipment need to be able to meet the dyeing requirements of cotton fabrics.
Chemical fiber fabric dyeing machine
Features: Since the chemical properties and physical structure of chemical fiber fabrics are different from those of natural fiber fabrics, they need to be dyed at higher temperatures and pressures. The equipment needs to have high temperature and high pressure resistance to ensure the dyeing effect and quality.
Silk fabric dyeing machine
Features: Silk fabrics are soft and delicate, and have high requirements for dyeing uniformity and color. The equipment needs to have mild dyeing conditions to avoid damage to silk fabrics. At the same time, the formula of dye liquor and dyeing process also need to be adjusted according to the characteristics of silk fabrics.
Different types of fabric dyeing machines have their own characteristics and are suitable for different fabrics and dyeing requirements. When choosing a fabric dyeing machine, it is necessary to comprehensively consider the actual production situation and the characteristics of the fabric to select the most suitable equipment.
