One of our common fabrics, nonwovens, has been widely used in all walks of life at this stage. Nonwovens dyeing needs the support of masterbatch, then, how non-woven masterbatch is produced, we will explore it today!


Non-woven masterbatch production process is generally divided into: kneading method, metal soap method, washing method, ink four.


1. Kneading: The pigment and oily vehicle are blended, the use of pigment lipophilicity of this feature, by kneading the pigment from the water phase into the oil phase. At the same time, the surface of the pigment is coated with an oily carrier to stabilize the pigment dispersion and prevent the pigment from aggregating.


2. Metal soap method: the pigment after grinding the particle size of about 1μm, and at a certain temperature was added soap, so that each pigment particle surface layer is uniformly wetted by the soap liquid to form a layer of saponification liquid, when the metal salt After the solution is added, it chemically reacts with the saponified layer on the surface of the pigment to form a protective layer of the metallic soap (magnesium stearate), so that the finely grained pigment particles do not cause flocculation and thus protect a certain degree of fineness .


3 rinse method: the pigment, water and dispersant by sanding, the pigment particles less than 1μm, and by phase transfer method, the pigment into the oil phase, and then dried masterbatch. Phase inversion requires the use of organic solvents, and the corresponding solvent recovery unit. The process is thin paste rinse evaporation concentrate drying Add carrier extrusion granulation.


4. Ink law: As the name implies, is the production of masterbatch in the use of ink color paste production method, that is, through the three-roll grinding, the pigment surface coated with a protective layer of low-molecular weight. The ground fine paste is mixed with the carrier resin and then plasticized by a two roll mill (also called a two roll mill) and finally pelletized by a single or twin screw extruder. Process is the ingredients mixing coarse paste three-roll grinding fine paste two-roll plastic extrusion granulation.



Albert believe that in accordance with the above four non-woven color masterbatch production process, the quality of the masterbatch produced can be guaranteed!
