Matters Needing Attention In Textile Dyeing And Finishing Process

Textile dyeing and finishing process is the process of obtaining the required color, pattern, feel, strength and other properties of textile after a series of processes. Textile dyeing and finishing processes are divided into four basic processes: pre-treatment, dyeing, printing and finishing. The specific processes vary according to the different products.

The following are the matters needing attention in the process of textile dyeing and finishing:

1. Determine the dyeing type and process

Before dyeing and finishing, it is necessary to determine the type of dyeing and process required. Different dyeing types and processes can have different effects on the process and the quality of the finished product, so the right choice must be made.

2. Choose suitable dyes and auxiliaries

The choice of dyes and auxiliaries will directly affect the color and feel of the finished products, so it is necessary to choose suitable dyes and auxiliaries. At the same time, the quality of dyes and auxiliaries also needs to be guaranteed to ensure the quality of finished products is stable. For example, cotton materials need cotton fixing agent, while polyester materials choose polyester fixing agent.

3. Determine the appropriate dyeing temperature and time

Dyeing temperature and time have great influence on the color and feel of the finished product. Before dyeing, it is necessary to determine the appropriate dyeing temperature and time according to different dyes and fiber materials.

4. Control environmental factors in dyeing process

In the process of dyeing, environmental factors also have a great impact on the color and feel of the finished product. Therefore, it is necessary to control the temperature, humidity, oxygen content and other environmental factors to ensure the color and feel of the finished product is stable.

5. Control mechanical factors in dyeing process

The mechanical factors in dyeing process also have great influence on the color and feel of finished products. Therefore, attention should be paid to the control of mechanical factors during dyeing process to prevent the tear, deformation and other problems of finished products.

6. Ensure the health and safety of dyeing processing

Dyeing process requires the use of some chemicals and additives, so it is necessary to ensure health and safety, to prevent chemical harm to the human body.

It is also necessary to strictly control the discharge and waste water treatment of dyeing process. The waste water and waste gas produced in dyeing process contain a large number of harmful substances, so it is necessary to strictly control the discharge and waste water treatment, in order to protect the environment and human health.

In short, textile dyeing and finishing process needs to pay attention to many matters, from the selection of raw materials to dyeing processing, treatment of waste water and discharge links need to be carefully grasped. Only by strictly controlling the selection of textile auxiliaries and fully mastering each link, can we ensure the product quality and production efficiency.
