Melt-Blown Material: The Key to Effective Mask

As the seasons change and we move into the fall and winter months, we enter a period when respiratory diseases are more prevalent. At this time, masks become an essential tool for our daily protection. But how do masks filter out bacteria and viruses? The answer lies in their core material—melt-blown fabric.

A typical mask is composed of three layers of non-woven fabric, known as the SMS structure: the outer and inner layers are spunbond fabric, and the middle layer is melt-blown fabric. Melt-blown fabric is made up of randomly distributed polypropylene ultrafine fibers with a fineness of 0.5-1.0 micrometers. These ultrafine fibers form a three-dimensional web structure that can capture and block airborne particles, including bacteria and viruses. The filtration efficiency of melt-blown fabric follows a "smiling curve," where it can adsorb nanoparticles less than 0.1 micrometers in diameter through electrostatic adsorption, and larger particles greater than 10 micrometers through physical structure adsorption.

Melt-blown material, as the raw material for making melt-blown fabric, has a direct impact on the filtration effectiveness of masks. Melt-blown material comes in two types: regular and electret-enhanced. Regular melt-blown material filters particles through physical means, while electret-enhanced melt-blown material has added electrostatic charge through the addition of electret powder or through electret treatment, enhancing the adsorption capacity for particles. Electroretreated melt-blown fabric has characteristics such as low resistance, high efficiency, and high dust holding capacity, with a filtration efficiency of more than 70% for particles with a diameter of 0.3 micrometers.

Among the many manufacturers of melt-blown material, Zhejiang Honye New Materials is a professional manufacturer of melt-blown material. The company's melt-blown material is known for its good processability, narrow molecular weight distribution, and fully dispersion. We also offer electret melt-blown material with high-efficiency electret masterbatch, which eliminates the need for mixing, saving time and effort. Zhejinag Honye's products are widely used in industries such as non-woven fabrics, medical protective clothing, masks, and water filtration materials. With their excellent performance, they provide high-quality raw materials for masks and other protective products, ensuring the filtration and protective performance of these products. Through their professional technology and strict quality control, Zhejiang Honye contributes significantly to public health and safety.
