Performance and quality requirements of polypropylene masterbatches

(1) The pigment used in dispersive masterbatch should have excellent dispersibility, and should be evenly dispersed in the color masterbatch, and the dispersant used will not reduce the quality of polypropylene fiber. Otherwise, it can not produce good quality stock solution coloring fiber, and the operation is unstable, and it is easy to break or produce abnormal fiber when drawing the fiber.

(2) Brightness polypropylene stock coloring has a variety of uses, which is used for bed cover base cloth and knitted fabrics, requiring bright colors. Because organic pigments are bright and bright, and easy to color, organic pigments should be used for the above purposes.

(3) Light resistance under the action of light some pigments have a photosensitive effect, so that the color fiber fade and brittle damage, and the light resistance of the pigment is basically related to its chemical structure, so in the production of color masterbatch to pay full attention to the light resistance of the pigment, light resistance of the pigment need to be used, you can consider adding ultraviolet absorber.

(4) The pigment used in the stability polypropylene masterbatches should have excellent stability for the colored polypropylene fiber. That is to say, when the colored fiber polymer is exposed to heat, light or high temperature for a long time, the pigment will not react with the fiber, forming new chemical groups to make the polymer performance low. Therefore, the color masterbatch should be selected as pure as possible, without impurities such as iron, copper, lead and other salts, to ensure that the physical properties of colored polypropylene fibers are excellent.

(5) Water resistance, dry cleaning resistance, oil resistance, colored polypropylene fiber products in use and in the inevitable to be washed or solvent dry cleaning, to contact with oil, especially for carpets, so the use of colorants to have good water resistance, dry cleaning resistance, oil resistance.
