How to choose the pigment of the functional masterbatch? What is the selection technique?
The heat-resistant functional masterbatch selected pigments, the most basic requirements can withstand the temperature of the polypropylene fiber production process, to maintain its performance stability. The temperature resistance temperature is generally required to be 270~280°C or more.
The dispersing functional masterbatch pigment should have excellent dispersibility and uniform dispersion in the functional masterbatch, and the dispersant used does not reduce 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.
The brightness of the polypropylene 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.
Light resistance Some pigments have a photosensitizing effect under the action of light, which causes the colored fibers to fade and be brittle. The light resistance of the pigment is basically related to its chemical structure. Therefore, attention should be paid to the light resistance and light resistance of the pigment when making the functional masterbatch. When the pigment needs to be used, it is considered to add a UV absorber.
The pigment used in the stability function masterbatch has excellent stability to pigmented polypropylene fibers. 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.
