In the coloring process of polypropylene fibers, polypropylene masterbatch plays a crucial role. It can not only endow polypropylene fibers with rich colors, but also enhance the overall quality of the products. However, to fully leverage the advantages of polypropylene masterbatch, correct usage is the key.

Before using polypropylene color masterbatch, it is necessary to ensure its quality first. High-quality polypropylene masterbatch should have good heat resistance, dispersibility and stability, and be able to maintain bright colors without fading during high-temperature spinning. When choosing the appropriate masterbatch, the denier number of polypropylene fibers should be taken into account. Fine denier grade fibers should be selected with fine denier grade masterbatch, while coarse denier grade fibers should be chosen with coarse denier grade masterbatch to ensure uniform and consistent color.

When mixing in polypropylene chips, it is necessary to ensure that the color masterbatch is evenly dispersed. The weight method and volume method can be adopted. After the color masterbatch is melted in the extruder or at the rear, it is injected into the polypropylene melt with a small extruder to achieve good uniformity. Meanwhile, in order to reduce the color difference of the fibers after color matching, the color masterbatch needs to be diluted and the mixing ratio strictly controlled. The proportion of long filaments mixed in is generally no less than 3% - 10%, while that of short fibers is no less than 1% - 3%.

During the production process, the temperature setting of the equipment is also very important. The temperature near the discharge port should be slightly higher to enable the color masterbatch to melt quickly and mix evenly with the plastic resin as soon as possible. In addition, applying an appropriate amount of back pressure can enhance the mixing effect of the screw and facilitate the dispersion of pigments, but it may slow down the injection molding speed.

When using polypropylene masterbatch, attention should also be paid to the storage conditions. The product should be packaged in double layers. The inner layer is a waterproof and moisture-proof polyethylene film bag, and the outer layer is a paper-plastic composite bag. The standard packaging is 25 kilograms per bag. It should be stored in a well-ventilated and dry place, with padding underneath, and protected from direct sunlight and rain. After opening and using the package, the remaining part should be resealed to prevent dust contamination and moisture absorption.

The correct use of polypropylene masterbatch can bring bright and lasting colors to polypropylene fibers and enhance the market competitiveness of the products. During the production process, every link needs to be carefully controlled in order to fully leverage the role of polypropylene masterbatch and create high-quality polypropylene fiber products.
