Proof of printing
Can be carried out from three aspects of paint anti-printing activity. One is mechanical anti-printing; the second is to damage the reactive dye on the dye conditions; third is to destroy the reactive dyes. Mechanical anti-printing is printed on the fabric before the printing paste, in the fabric to form a layer of about a few microns thick film, the post-printed reactive dyes play a mechanical anti-dye effect. Destruction of reactive dyes on the conditions of dyeing is - the use of acid-release anti-offset agent and active paste in the alkali agent to control the active color of the pH value of 7 or less to destroy the reactive dye on the dyeing conditions. Destruction of reactive dyes is - the use of reduced anti-print agent directly after the destruction of reactive dyes to achieve anti-print.
Since the acid releasing agent is more stable than the reducing agent, the antacid agent is generally used as an anti-offset agent in the actual production. Many types of acid release agent, after comparative tests found that the use of ammonium sulfate as a sealant for the printing of the color profile is relatively clear, stained light, easy to control the process. Therefore, in the paint anti-printing paste by adding the right amount of ammonium sulfate can do anti-printing agent. The ammonium sulfate in the coating paste is neutralized with the alkali agent in the active colorant, thereby destroying the fixing conditions of the reactive dye and acting as an anti-printing agent. The reaction formula is as follows:
(NH4) 2SO4 + 2NaHCO3 → Na2SO4 + 2NH4HCO3
NH4HCO3 → NH3 ↑ + H20 + CO2 ↑
According to the acid and alkali neutralization reaction, theoretically available ammonium sulfate dosage and alkali dosage of the mass ratio of 66:84, that is to say the amount of ammonium sulfate is slightly lower than the amount of soda can be used. In the actual production, due to the fabric of the reactive dyestuffs after the absorption of the amount of small, so the amount of ammonium sulfate is also a corresponding reduction should be controlled within 1.5%. For some of the reactive dyes can not be printed, may be appropriate to increase the amount of ammonium sulfate, but the excessive use of ammonium sulfate drawbacks is to make cotton fiber fragile, affecting the fabric strength and feel, so the amount of ammonium sulfate can not be too much control Within 3%.
