How about the production process and performance characteristics of non-woven masterbatch?

non-woven masterbatch is a special particle used for non-woven dyeing, it plays an important role in the production process of non-woven fabrics, so what about the production process and performance characteristics of non-woven masterbatch? Take you to see more.

Mixing stage

First, the pigment or dye, carrier resin and dispersant are mixed in a high-speed mixer in a certain proportion. The key at this stage is to ensure that the components are fully in contact to prepare for subsequent dispersion and extrusion. The speed and mixing time of the mixer will be adjusted according to the formula and production requirements. For example, a higher rotational speed and appropriate mixing time can make the ingredients mix more evenly.

Extrusion granulation stage

The mixed material is fed into the twin-screw extruder. In the extruder, the raw material gradually melts and forms a uniform melt under the shearing action of the high temperature (generally about 180-250 ° C, the specific temperature depends on the type of carrier resin) and the screw. The pigment or dye is further dispersed in the melt during this process. Then, the melt is extruded through the mold, and after cooling, granulation and other links, the non-woven masterbatch is finally formed.

Performance characteristics

Color property

High color intensity: the non-woven masterbatch can give the non-woven fabric bright and full color. Because the pigment or dye has been finely dispersed in the color masterbatch, it can be evenly dyed in the non-woven fabric, making the color more intense. For example, the color non-woven fabric produced with high-quality masterbatches can maintain its color brightness for a long time and will not fade easily.

Good color stability: whether under the influence of light, high temperature or chemical substances, the non-woven fabric after dyeing the masterbatch can maintain good color stability. This is because the pigments and dyes in the masterbatch have been screened and have good light resistance, heat resistance and chemical resistance. For example, the color masterbatch of non-woven fabrics used in outdoor advertising can ensure that the color of non-woven fabrics is basically unchanged even under long-term sunlight.

Dispersion property

Excellent dispersion property is one of the important characteristics of non-woven masterbatch. In the production process of non-woven fabrics, the color masterbatch can be evenly dispersed in the non-woven raw materials, and there will be no color spots or uneven color phenomenon. This is due to the use of dispersants and good production processes in the production of masterbatches, ensuring that the pigment or dye particles are evenly distributed in both the carrier resin and the final non-woven raw material.

Compatibility with non-woven materials

non-woven masterbatch has good compatibility with the main raw materials of non-woven fabrics (such as PP, PE, etc.). Because the choice of carrier resin is usually matched with the raw material of the non-woven fabric, the color masterbatch can be well integrated after mixing with the raw material, and will not have adverse effects on the physical and chemical properties of the non-woven fabric. For example, it will not reduce the strength, permeability and other properties of non-woven fabrics.
