What are the performance characteristics of PP masterbatch?

(1) The pigment selected for the heat-resistant PP masterbatch, the most basic requirement can withstand the temperature during the production of polypropylene fiber, and maintain its performance stable. The temperature resistance temperature is generally required to be 270 to 280 ° C or higher.

(2) The pigment for the dispersible PP masterbatch is excellent in dispersibility, and is uniformly dispersed in the masterbatch, and the dispersant used does not lower the quality of the polypropylene fiber. Otherwise, it is impossible to produce a good quality colored liquid of the raw liquid, and the operation is also unstable, and it is easy to break or generate abnormal fibers when the fiber is drawn.

(3) The brightness of the stock solution has a variety of uses, among which the bed cover base fabric and the knitted fabric require a bright color tone. Since organic pigments are bright and vivid, and are easy to color, organic pigments are required for use in the above applications.

(4) Light resistance Some pigments have a photosensitizing effect under the action of light, which causes the colored fibers to fade and be brittle, and the light resistance of the pigment is basically related to its chemical structure. Therefore, attention should be paid to the light fastness of the pigment when making the masterbatch. When a light-resistant pigment is used, it is conceivable to add a UV absorber.

(5) The pigment used in the stability PP masterbatch has excellent stability to the colored polypropylene fiber. That is to say, when the colored fiber polymer is exposed to heat, light or subjected to high temperature for a long time, the pigment does not react with the fiber, and a new chemical group is formed to degrade the polymer performance. Therefore, the color masterbatch should be selected as pure pigment as possible, free of impurities such as iron, copper, lead and the like, to ensure the physical properties of the colored polypropylene fiber is excellent.

(6) Water resistance, dry cleaning resistance, oil resistance, coloring PP products are inevitably washed or solvent dry cleaned in use and in contact with oil agents, especially when used on carpets, so the colorants used must have Good washability, dry cleaning resistance and oil resistance.
