Which color masterbatch is your non-woven fabric product compatible with? Choose based on the specific application scenario! 

Non-woven fabric color masterbatches are widely used for coloring and functional enhancement in processes such as PP spunbonding, meltblown, and waterjetting. Different end products have varying requirements for color masterbatches, and choosing the right one can effectively enhance production efficiency and product quality. Below, we will help you match them according to common application scenarios. 

1. Eisai and medical non-woven fabrics (masks, protective suits, diapers, sanitary pads) 

These products come into direct contact with the skin, so they have higher requirements for the purity, safety and dispersion of the color masterbatch. 

Recommendation focus: Select high-purity, non-migrating polypropylene color masterbatches. The carrier has good compatibility with the PP substrate, reducing the risk of crystal points or mesh blockage during the spinning process. 

Additional requirement: The masterbatch must comply with relevant safety standards (such as RoHS, REACH, etc.) and be non-irritating to the skin. If antibacterial or hydrophilic functions are required, one can directly choose hydrophilic masterbatch or antibacterial function masterbatch. This will not only color the non-woven fabric but also provide additional properties, reducing the need for subsequent spraying processes. 

II. Medical non-woven fabrics (surgical gowns, isolation gowns, bed sheets) 

In medical scenarios, in addition to basic coloring, it is often necessary to have barrier properties and anti-static functions. 

Recommendation focus: Flame-retardant masterbatch or anti-static masterbatch should be used in combination with color masterbatch. For flame-retardant non-woven fabric, it is recommended to use the flame-retardant masterbatch addition method. The function is distributed within the fibers, which is more resistant to washing and friction compared to the post-treatment coating. 

Color selection: Medical supplies usually adopt light color schemes such as blue and green. There is a high requirement for controlling color differences between batches. It is recommended that the supplier provide color comparison charts of multiple batches in the recent period. 

III. Non-woven fabric packaging (shopping bags, gift bags, laminated bags) 

The packaging non-woven fabric places greater emphasis on color vibrancy, uniformity and printing adaptability. 

Recommendation focus: Select high-dispersibility color masterbatches to ensure uniform color distribution over large areas and no flow marks. The fluidity of the carrier material should match the spinning process to avoid color spots caused by poor dispersion of the masterbatch. 

Additional features: If you need to enhance the stiffness or anti-aging properties of the bag (for outdoor display purposes), you can use the functional masterbatch in combination. 

IV. Agricultural non-woven fabrics (seedling cultivation fabric, weed prevention fabric, insulation fabric) 

In agricultural applications, the non-woven fabric is usually required to have certain anti-aging properties and weather resistance, and its color tends to be darker. 

Recommendation focus: For anti-aging non-woven fabric, it is recommended to use anti-aging masterbatch (with the addition of UV stabilizers) combined with color masterbatch. When used outdoors for a long period, the lightfastness grade of the color masterbatch itself needs to be paid attention to to avoid fading in a short time. 

Color customization: Dark colors such as black and green are beneficial for resisting aging in agricultural fabrics. However, it is important to ensure the uniformity of carbon black dispersion to avoid a decrease in local strength due to agglomeration. 

V. Filtered Non-woven Fabrics (Air Filtration, Liquid Filtration) 

The filter material has strict requirements for the purity and particle size distribution of the masterbatch. Impurities or large particles may affect the filtration efficiency. 

Recommendation focus: Select high-purity color masterbatches that have undergone precise filtration to reduce the increase in filtration pressure during the spinning process. The carrier has a high consistency with the PP substrate, avoiding the formation of incompatible gels. 

Summary and Selection Suggestions 

When purchasing non-woven fabric color masterbatches, it is recommended to follow the steps below for confirmation: 

Primary application: Eisai, healthcare, packaging, agriculture or filtration? Different scenarios have different requirements for purity, light resistance, and functions (hydrophilic/flammable resistance/anti-aging). 

Clarify the process again: are we using spunbonding, meltblown, or needling? The spinning speed and temperature affect the selection of the heat resistance grade of the masterbatch. 

Finally, the sample is put into use: conduct a small-scale trial on your production line to observe the dispersion effect, color accuracy, as well as the impact on filtration pressure and breakage rate.
