The pre-treatment is necessary for fabrics before printing to ensure the best printing results, for woven fabrics or knitted fabrics, because the residues, addition agent and chemicals used in production shall be removed to avoid affecting the printing effect.
After mercerization, the dye yield, brightness and wet/dry fastness of printing can all be improved for woven fabrics or knitted fabrics.
Dye printing
When selecting the WORLD brand P-type reactive dyes in the dye printing, dyeing, using the soda as alkaline agent can achieve better effect, and the soda ash can also be used as alkaline agent.


There are four points:
( 1 ) the utilization rate is not high enough, generally 60 % ~ 70 %, produce a large amount of colored sewage, its chroma is more than 1000 times, the cod value is generally 0.8 ~ 30 thousand ppm, the cod value of concentrated wastewater is more than 50 000 ppm.
( 2 ) in order to suppress the charge of the fiber surface, the active dyes use a considerable amount of electrolyte, not only increase the intensity of labor, but also caused the concentration of chloride ion in wastewater up to more than 10 million ppm, greatly increase the difficulty of treating reactive dyeing wastewater.
( 3 ) some color fastness can not meet the market requirements, such as perspiration, wet rubbing fastness and the fastness of azo - red dye and azo blue dye in light color.
( 4 ) there are few dark varieties which can replace sulfide and vat dyes.
The main way to solve the technical problems existing in reactive dyes is to improve their sorption rate and fixation rate, and the most effective method is to introduce two heterogeneous or homologous active groups into reactive dyes, in particular the former is the introduction of two active groups - Uniform and ethylene. For a new reactive dye comprising the two heterogeneous active groups and the appropriate parent dyes and the bonding group, in addition to the characteristics of the various constituent active groups, such as low acid hydrolysis rate, high acid hydrolysis breaking stability, excellent ke, good fastness and low sorption rate and fixation rate, the new characteristics, such as better acid resistance hydrolysis and peroxide washing ability, higher fixation rate, wider range of dyeing temperature, better dyeing reproducibility and suitable for.
