[ Cationic Leveling Agent  General Information] When the cationic dye is used to dye acrylic fiber, due to the negative charge of the third monomer of the acrylic fiber, resulting in the dyeing speed too fast and the spread speed too slow, thus prone to dye flower phenomenon. Especially in the three primaries combination, this phenomenon is more serious, so the requirements higher. In order to solve this problem, it is usually necessary to add leveling agent in the process of dyeing and finishing. The main functions of the leveling agent include the effects of retarding, removing, osmosis and cleaning. cationic Leveling agent The leveling agent is usually surfactant, as a cationic surfactant for acrylic fabric, there are two types: quaternary ammonium salt cationic surfactants and electrolyte leveling agent in 1000 ~ 2000 of polymer molecular weight developed in recent years.  It is a dispersing and  leveling agent  for cationic dyes for acrylic in the same ...

Ink Sublimation Printing ink is the key material of dye sublimation printing technology which is mainly composed by the disperse dyes, connecting materials, solvents and a few additives. The dye must have a good sublimation transferability and permeability to reach a certain fastness index. Molecular weight is 23O ~ 380 and sublimation temperature is 180 ℃ ~ 240 ℃. The common printing dye is anthraquinone dyes, azo dyes, and cationic dyes( cationic leveling agent ) . Temperature and time Dye sublimation printing technology requires temperature control in the range of 180 ℃ ~ 230 ℃, the time is about 10 ~ 30s, and at the same time pay attention to the reasonable deployment of temperature and time. Pressure Pressure is also one of the important parameters of dye-sublimation printing technology. If the pressure is appropriate, the gap between the flat fabric and transfer paper are suitable, the transfer coloring effect will be good with a clear pattern and smooth lines. Other factor...
