Which color masterbatch is suitable for your non-woven fabric/fiber products? Choose based on the specific application scenario. 

Polypropylene color masterbatches, non-woven fabric color masterbatches, and other products are widely used in various fields such as chemical fiber spinning, non-woven fabric production, injection molding, and blow molding. Different processes and final products have different requirements for color masterbatches. Below, we will help you match them according to common application scenarios. 

1. Non-woven fabrics (such as spunbond, meltblown, needling, etc.) 

This type of process requires that the color masterbatch have good dispersion in the substrate and a low filtration pressure rise, to avoid the occurrence of color spots or clogging of the screen. 

Recommended direction: Non-woven fabric-specific color masterbatch, the carrier has good compatibility with base materials such as PP/PE, and the pigment's temperature resistance matches the spinning temperature. 

Additional requirement: When used for Eisai or medical non-woven fabrics, the color masterbatch must meet relevant safety standards and be non-irritating to the skin. 

II. Chemical Fibers (Polypropylene, Polyester, Nylon Filaments/Short Fibers) 

The spinning of chemical fibers has higher requirements for the heat resistance, migration resistance and batch stability of color masterbatches, especially for fine denier fibers. 

Recommended direction: Polypropylene color masterbatch, polyester color masterbatch or nylon color masterbatch. Select the corresponding carrier based on the type of fiber to reduce filament breakage. 

Color consistency: When making multiple batch purchases, it is necessary to pay attention to the color difference control of the color masterbatch. It is recommended to request a color comparison chart from the supplier. 

III. Plastic Products (Injection Molding, Blow Molding, Extrusion) 

When used for products such as plastic containers, sheets, and pipes, the color masterbatch needs to take into account both dispersibility and the retention rate of mechanical properties. 

Recommended direction: Plastic general color masterbatch or functional masterbatch (such as anti-aging, anti-static, etc.), and corresponding additives can be added according to the outdoor/indoor usage scenarios. 

Process matching: Different molding methods (injection molding/ blow molding/ extrusion) have different requirements for the fluidity and heat resistance of the masterbatch. It is recommended to communicate the processing conditions in advance. 

IV. Functional Masterbatches (anti-aging, flame retardant, anti-static, etc.) 

When the product requires additional functions, one can directly select the functional masterbatch or combine it with the color masterbatch for use. 

Recommended direction: Select the corresponding functions based on the usage environment of the final product. For example, choose anti-aging masterbatch for outdoor products and anti-static masterbatch for electronic packaging. 

Blending suggestion: When using functional masterbatch and color masterbatch together, pay attention to whether the carriers and addition ratios of the two affect each other. It is recommended to conduct a small-scale test first. 

Summary and Selection Suggestions 

When purchasing color masterbatch, it is recommended to follow the following steps for confirmation: 

First, determine the base material and process: PP, PE, PET or PA? Filament spinning, non-woven fabric, injection molding or blow molding? This determines the carrier and the temperature resistance level. 

Clarify the color and functional requirements further: Do you need custom color matching? Do you require additional features such as anti-aging or flame retardancy? 

Finally, the samples were put into actual production for testing: small-scale trial spinning or trial injection molding was conducted to observe the dispersion effect, color accuracy and processing stability.
