Polypropylene is a pure hydrocarbon, the molecular chain contains tertiary carbon atoms, heat, light received in the tertiary carbon atoms at the molecules easy to crack, so that the deterioration of the quality of polypropylene, so that the required masterbatch in high temperature spinning Easy to spread, do not destroy the fiber character, do not make the fiber fade, excellent light resistance, wear resistance, solvent resistance, bear the harsh spinning draft.

(1)
Solid color masterbatch used in the pigment, the coloring of polypropylene fiber to have excellent stability. That is, coloring fiber polymer by a long time to fight the heat, light or play when the high temperature pigment will not react with the fiber, the formation of new chemical groups make the polymer performance low. So the masterbatch should be used to make pure pure pigments, non-iron, copper, lead and other salt impurities, to ensure the physical properties of polypropylene fiber fiber fine.
 
(2)
Heat-resistant polypropylene masterbatch The choice of pigments, the most fundamental requirements of the polypropylene fiber production process can withstand the temperature, to maintain its stable performance. Temperature temperature is usually required for more than 270 ~ 280 ℃.
 
(3)
Evacuation of masterbatch with pigments should be evacuated, and in the masterbatch to evacuate symmetry, and the use of the dispersant will not lower the quality of polypropylene fiber. Or can not produce a good quality of the original liquid coloring fiber, running is not stable, easy to break in the drawing fiber or produce a very fiber.

(4)
Light resistance In the light of the role of some pigments have a photosensitive effect, so that coloring fiber fade and brittle, and the light resistance of the pigment is essentially related to its chemical layout, so in the production of masterbatch to enrich the fine pigment lightfastness, light When the pigment is necessary for use, it is possible to consider adding an ultraviolet absorber.
 
(5)
Water resistance, dry cleaning resistance, oil resistance, coloring of polypropylene fiber products in the use and can not help but after washing or solvent dry cleaning, to fight to the oil, especially for the carpet, so the use of colorants to Excellent washing resistance, dry cleaning resistance, oil resistance.

(6)
Brightness Polypropylene liquid coloring has a variety of uses, which for bedspreads and knitted fabrics, requiring bright colors. Because the organic pigment is bright and beautiful, and easy to color, so where the use of the use of organic pigments.
