This article will cover the 25 most common substandard problems in woven fabric printing and dyeing. For example, the colour differences in various positions on the fabric and the reasons for them

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.
