The color master production process is very strict, and the wet process is generally employed. The color-mother pellets are ground through the aqueous phase, transparent, washed, dried, and granulated, (Shanghai white mother) is only guaranteed.

In addition, the pigment should be carried out while grinding treatment, such as determining the fineness of the sand mill, determines the diffusion properties of the sand grinding slurry, and the solid content of the sand slurry and the measurement of color slurry are measured.

Polypropylene masterbatch performance requirements:

1. The tandem selected by heat-resistant masterbatch, the most basic requirement to ensure the temperature during the inner end, maintain its performance stability. Temperature is generally required to be 20-80 or more.

2. The pigment of dispersible color masterbatch should be excellent in dispersibility, and uniform dispersion in color motheropasis, and the dispersant used does not reduce the quality of polypropylene fibers. Otherwise, it is not possible to produce a good quality of the original liquid coloring fiber, and the operation is not stable, and it is easy to break or produce abnormal fibers during drafting fibers.

3. The brightness of the polypropylene ravine has a variety of uses, which are used in the bed cover base fabric and knitted fabrics, require bright hue. Since the organic pigments are relatively bright and easy to color, there is an organic pigment that is used for the above use.

4. Night resistance is a photosensitive effect in the action of light, (antistatic masterbatch) makes coloring fibers fade and brittle, and the light resistance of the pigment is substantially related to its chemical structure, so it is sufficient when making color Note that the light resistance of the pigment, when the light-resistant pigment needs to be used, it can be considered to add an ultraviolet absorber.

5. The pigments used in stabilizing the parental particles have excellent stability to the polypropylene fibers. That is, the coloring fiber polymer does not react with the fiber when the color is touched with heat, and the pigment does not react with the fiber when the light is subjected to high temperature, and the new chemical group is formed to make the polymer. So the color masterbatch should be used as pure pigment, free of iron, copper, lead and other impurities to ensure excellent physical properties of the polypropylene fibers.

4. Water resistance, daring resistance, oil resistance, the amorphous fibrous article is used in use and difficult to clean or solvent dry cleaning, to contact the oil, especially for the carpet, so the coloring agent thereof Good water-resistant, daring resistance, oil resistance.

The polypropylene masterbatch  has good quality stability, special dispersibility, and quality assurance.

Polypropylene masterbatch can be used directly with mixed resin, non-contaminated container, easy to change color; provide monochrome and full concentration pre-decreasing pigment, which is easy to produce high-quality organic pigments and inorganic pigments and aids.

Polypropylene masterbatch  is characterized by filtration performance, bright color, good inductance, no migration, especially suitable for polypropylene splicing non-woven fabric, polypropylene filament, polypropylene short wire, polypropylene BCF wire use.
