1. Introduction of non-woven masterbatch:

Polypropylene non-woven fabric masterbatch has good quality stability, excellent dispersibility, and quality is guaranteed; it can be used directly with mixed resins, does not pollute the container, and is easy to change colors. This product is made of high-quality organic pigments and inorganic pigments and additives. It is characterized by good filtering performance, bright colors, good weather resistance, and no migration. It is especially suitable for polypropylene spunbond non-woven fabrics, polypropylene filaments, and polypropylene fibers. Short yarn and polypropylene BCF yarn are used.

2. Main technical indicators of non-woven masterbatch:

1. Appearance: The cylinder has uniform particles and consistent color

2. Excellent spinnability

3. Heat resistance ≥230℃

4. Migration resistance ≥ grade 4

5. Lightfastness ≥6 grade

6. Moisture content (%) ≤0.2

7. Total color difference (CIELAB) ΔE<1.5

3. The proportion and method of using non-woven masterbatch:

The non-woven masterbatch can be mixed with the raw material resin in a certain proportion (specifically according to the specifications of the non-woven fabric and user requirements), and it can be used directly by simple stirring and mixing (without adding any additives) to achieve the required Color effect. Mix polypropylene non-woven fabric masterbatch and polyolefin resin in a ratio of 1.5 to 3% (specifically, it can be determined according to the requirements of the product's opening performance), and then normal processing can be carried out.

Fourth, the advantages of using non-woven masterbatch

Ensure that the pigment achieves the ideal dispersion effect, and realize the color stability of different batches of colored products;
