Non-woven masterbatch is a new coloring product that integrates plastics and fibers. It is mainly divided into three parts: coloring agent, carrier and dispersing agent. The non-woven masterbatch can produce a polymer by uniformly and uniformly loading the pigment into the resin.

In terms of variety development, China's masterbatch manufacturers have developed non-woven masterbatch. The production process of non-woven masterbatch is generally divided into four types: washing method, ink method, kneading method and metal soap method. The following four production processes for non-woven masterbatch are described below:

1. Flushing method: the pigment, water and dispersing agent are sanded to make the pigment particles smaller than 1 μm, and the pigment is transferred to the oil phase by a phase transfer method, and then dried to obtain a masterbatch. An organic solvent, as well as a corresponding solvent recovery unit, is required for phase inversion.

The process is as follows: fine color slurry washing, evaporation concentrated material drying and adding carrier extrusion granulation.

2. Ink method: In the production of masterbatch, the production method of ink paste is adopted, that is, a three-roll mill is used to coat a surface of the pigment with a low molecular protective layer. The ground fine color paste is then mixed with a carrier resin, then plasticized by a two-roll mill (also called a two-roll mill), and finally granulated by a single-screw or twin-screw extruder.

The process is as follows: the ingredients are stirred and the coarse color paste is tri-rolled, and the fine color paste is subjected to two-roll plasticating extrusion granulation.

3. Metal soap method: after the pigment is ground, the particle size reaches about 1μm, and the soap liquid is added at a certain temperature, so that the surface layer of each pigment particle is uniformly wetted by the soap liquid to form a saponification liquid, as a metal salt. After the solution is added, it chemically reacts with the saponified layer on the surface of the pigment to form a protective layer of metal soap (magnesium stearate), so that the finely divided pigment particles do not cause flocculation, but protect a certain fineness. .

4. Kneading: After blending the pigment and the oily carrier, the pigment is lyophilized to wash the pigment from the aqueous phase into the oil phase by kneading. At the same time, the surface of the pigment is coated by an oil carrier to stabilize the dispersion of the pigment and prevent the pigment from agglomerating.

Polypropylene is a pure hydrocarbon with a tertiary carbon atom in the molecular chain. It is heated and is easily cleaved at the tertiary carbon atom after being exposed to light, which deteriorates the quality of the polypropylene. Therefore, the prepared masterbatch is required to be spun in high temperature. It is easy to spread, does not damage the fiber quality, does not fading the fiber, has excellent light resistance, abrasion resistance, solvent resistance, and can withstand strict spinning drafting.
