Printing and dyeing processing after finishing content can be summarised as two aspects, on the one hand, focus on improving and playing all kinds of fibres inherent performance, such as fabric moisture absorption, softness, gloss, size stability, dyeing fastness improvement, etc., through a certain finishing (such as stenter, shrinkage, rolling light, etc.), the excellent characteristics of all kinds of fibres fully displayed; on the other hand, focus on giving fibres new performance, such as flame retardant, water Waterproof, mould and moth resistant, UV resistant, easy to stain, etc. These properties are not available in all types of fibres, only through finishing to obtain the desired results.

Generally the former type of finishing called general finishing, and the latter type of finishing called special finishing or functional finishing. At present, the latter type of finishing has increased significantly, which has fully revealed the importance of finishing.

Gray fabric is a semi-finished product that has not been dyed and finished after the fibres have been spun into fabric. Dyeing and finishing companies often refer to uncooked and desized grey fabric as raw grey fabric. After cooking and desizing, the cloth is called cooked cloth.

The fabric formed by the yarn after weaving or knitting in a textile mill or knitting factory is generally referred to as grey fabric. As a semi-finished product in the textile and clothing processing process, the fabric is processed in dyeing and finishing plants for pre-treatment, dyeing, printing and finishing to achieve a certain appearance, feel and functional requirements before it can be used as clothing fabric or enter the textile distribution market. We refer to the pre-treatment, dyeing, printing and finishing of fabrics as a series of processes, which are collectively referred to as dyeing and finishing.

Most cotton fabrics are printed using reactive dyes. Improving the success rate of cotton reactive printing and controlling the colour difference within a reasonable range are important for improving production efficiency, saving energy and reducing production costs significantly. This paper summarises and analyses the factors that can easily cause colour difference in the production process according to the production practice and gives the corresponding control measures.

The general dyeing and finishing process is as follows：
Cloth preparation → head sewing → drop tank boiling and bleaching → dyeing → soaping → colour fixing → soft → out of the tank → dewatering → dry cloth, while the formation of fine wrinkles is mainly in the dyeing tank, in the dewatering machine, in the pile cloth car ….
Because a meter of cloth from the yarn to the finished product, after too many links, each link quality control is not done well, there is a risk of producing substandard fabrics.

Knitted fabrics because of its fabric characteristics, so the operation in the printing production process, necessarily with the woven fabric printing production process, there are relatively large differences and different. Reasonable and correct printing operation is to ensure and improve the quality and yield of knitted fabric printing key.

After finishing is to give the fabric to color effect, form effect (glossy, suede, brace, etc.) and the actual effect (impermeable, not felt shrinkage, non-iron, not moth-eaten, flame resistance, etc.) of the technical treatment, fabric finishing is through the main chemical or physical method to improve the appearance and feel of the fabric, enhance the performance or give special features of the process, is the textile “icing on the cake” process.

Printed fabric in the apparel industry is a large category, the following links and processes can be devided to many process and relative process, this time I will list the usual we use in gereneral to do a post and share out

Today I came to discuss with you the content of which fabrics are suitable for digital printing, in the textile digital printing industry, there are some textiles meet printing machine nozzle will appear off line, causing damage.

Today we bring some characteristics of cotton and linen fabrics, common quality problems and causes, what are the prevention methods and repair methods?
