Problems solved by technology

Second, poor level dyeing
The linear density of most new synthetic fibers is low, the lower the linear density, the faster the fiber absorbs the dye, and the worse the level dyeing property; the cross-section of new synthetic fibers is mostly irregular, and the surface is not smooth enough, making the specific surface Further increase, the dye adsorption rate will increase, and the dyeing levelness will become worse
In addition, for the sake of eco-environmental protection, low liquor ratio dyeing technology is currently required for dyeing. Low liquor ratio dyeing technology increases the difficulty of uniform dyeing of new synthetic fiber fabrics, and it is difficult to guarantee the level dyeing of new synthetic fiber fabrics.
Third, poor color fastness
The linear density of the new synthetic fiber is low, the proportion of the amorphous area is large, the dye is easy to migrate to the fiber surface when heated, and the irregularity of the fiber surface makes it difficult to wash the migrated dye, and the color fastness (including washing fastness and Rubbing fastness) decreased
When dyeing and finishing enterprises use traditional dyeing and finishing auxiliaries and dyeing and finishing processes to dye and finish new synthetic fiber fabrics, they need to use more dyeing and finishing auxiliaries and consume more water and electricity to make the fabric meet the dyeing and finishing performance requirements, which not only causes Excessive energy consumption also imposes a heavy burden on subsequent sewage and waste gas treatment
Since new equipment, new technologies and new processes are often difficult to solve these problems efficiently without the participation of new materials, it is therefore necessary to develop new dyeing and finishing auxiliaries to solve processing energy consumption and ecological environment problems from the source of dyeing and finishing imminent
