Polypropylene meltblown nonwoven fabric color masterbatch: The "Color Guardian" for Warm Winter protection！

At the end of November, the temperature dropped sharply and the temperature difference between day and night increased, leading to a rise in the demand for masks and warm protective equipment. As the core raw material of this type of product, the optimization of the color and performance of polypropylene meltblown nonwoven fabric cannot do without the assistance of polypropylene meltblown nonwoven fabric color masterbatch. This special color masterbatch uses polypropylene as the carrier and integrates high-quality pigments and functional additives. While endowing the material with rich colors, it does not affect the core protective performance of the meltblown fabric.

Core feature: Dual guarantee for meltblown process

The most prominent advantage of Polypropylene meltblown nonwoven fabric color masterbatch is its high compatibility with the meltblown process. The meltblown process needs to be carried out at high temperatures. The color masterbatch must have good heat resistance to ensure that it does not decompose or fade at processing temperatures above 250℃. Meanwhile, the pigment particles have undergone special treatment, with uniform fineness and excellent dispersibility, which can be integrated into ultra-fine meltblown fibers to avoid color spots and color differences.

For warm winter protection scenarios, some color masterbatches will add antistatic agents to enhance the antistatic performance of meltblown fabric and reduce dust adsorption. Products in the medical protection field use pigments that meet safety standards, ensuring they are non-toxic and odorless, and are suitable for direct contact with the skin. Its color fastness is stable. Even after multiple uses or disinfection, the color remains bright.

Production key: Precise control of detailed craftsmanship

The production process must strictly match the characteristics of meltblown non-woven fabric. First, select a carrier resin with excellent compatibility with polypropylene, combine it with heat-resistant pigments, mix them in proportion, and then add dispersants, heat stabilizers and other additives. Through high-speed mixing equipment, achieve uniform dispersion of the components. Subsequently, the color masterbatch is melted and granulated through a twin-screw extruder. The extrusion temperature and speed are well controlled to ensure uniform color masterbatch particles and a high degree of compatibility between the melt index and the meltblown raw materials.

In view of the characteristics of "ultra-fine fibers" in meltblown fabric, the pigment particles need to be refined to the micron level. Through special dispersion technology, agglomeration is avoided to ensure uniform dyeing without clogging the meltblown die head, thus guaranteeing the smooth progress of production.

Warm Winter Application: Diversified Implementation of Protection and practicality

In the field of personal protection, it dyes colored protective masks. Besides basic protection, the rich colors meet the needs of different scenarios. The bright color matching of children's special masks can further enhance the willingness to wear them. In the field of warmth preservation, meltblown non-woven fabric products such as cold-proof face masks and scarves are used. Dark-colored products can also absorb sunlight and heat, assisting in enhancing the warmth preservation effect.

In industrial protection scenarios, meltblown filter materials of different colors can be used to distinguish filtration grades, and the stable colors provided by color masterbatches make the markings clearer. In addition, it is also used in pet protective equipment, disposable warm gloves, etc. While meeting the color requirements, it maintains the breathability and flexibility of the material, becoming an indispensable important additive in warm winter protective equipment.
