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.

Four production processes of non-woven masterbatch

1

Rinsing 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 color master batch. An organic solvent, as well as a corresponding solvent recovery unit, is required for phase inversion.

2

Ink method: As the name implies, it is a production method using ink paste in the production of masterbatch, that is, a three-roll mill is used to coat a low-molecular protective layer on the surface of the pigment. 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.

3

Metal soap method: the pigment has a particle size of about 1 μm after grinding, 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, and the metal salt solution is added. After that, 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 and 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.

Non-woven masterbatch properties

Non-woven masterbatch is divided into: SMS non-woven masterbatch, spunbond non-woven masterbatch, meltblown non-woven masterbatch.

Non-woven masterbatch use: industrial fabrics, warp knitted fabrics, all kinds of non-woven fabrics and other products.

Non-woven masterbatch reference ratio: 1:25.

Non-woven masterbatch is divided into two parts according to color: black, porcelain white, red, fluorescent whitening, green, blue, fluorescent pink and other colored non-woven masterbatch. It can also be matched according to customer requirements.

Non-woven masterbatch features: good quality stability, excellent dispersibility, quality assurance; non-woven masterbatch can be used directly with mixed resin, does not pollute the container, easy to change color; provide monochrome and full Concentrated pre-dispersed pigments, easy to mix colors. Made of high quality organic pigments and inorganic pigments and additives. The non-woven masterbatch features good filtration performance, bright color, good resistance to repair and no migration.

Non-woven masterbatch storage: The product is double-layered, the inner layer is waterproof and moisture-proof polyethylene film bag, and the outer layer is paper-plastic composite bag. Standard packaging 25 kg / bag. Please store in a ventilated, dry place, place the underlay to avoid sun and rain, and the color of the masterbatch can be up to 5 years. The remaining part should be resealed after use of the unpacked bag to prevent dust pollution and moisture absorption.
