    12 Detailed Methods to Reduce the Resistance of Melt-Blown Fabric Summarized by Senior Technicians

    Maintaining the working efficiency of melt-blowing machines and minimizing the resistance of melt-blown fabric have become new issues that melt-blown fabric factories need to address currently. For example, for a 25g/m² melt-blowing fabric, it is ideal to control the single-layer resistance below 60Pa and the double-layer resistance below 120Pa at a flow rate of 85L/min; and control the single-layer resistance between 60-70Pa and the double-layer resistance below 150Pa at a flow rate of 95L/min

    Why is Polypropylene Widely Used in the Melt-Blown Process? What Are the Characteristics of Polypropylene?

    Polypropylene is widely used in the melt-blown process due to its following advantages:1.Controllable polymer viscosity: Thermal degradation can be achieved by using oxidants or peroxides in the extrusion process, or through the mechanical shearing effect of the extruder, or by controlling the operating temperature, so as to adjust and control the melt viscosity as required.

    New Developments in the Industry: Overcoming Nanofiber Research Processes Using Melt-Blown Technology

    Melt-blown technology is a crucial method for large-scale production of ultrafine fibers. Its principle is that polymer materials are extruded through spinnerets, and then further stretched under high-temperature and high-velocity airflows to form ultrafine fibers. The application of ultrafine fibers in melt-blown nonwovens is unparalleled by other products manufactured using a single nonwoven technology. Thanks to the availability of various raw materials that can be continuously used for melt-blowing, melt-blown nonwoven technology has developed rapidly, driving the growth of the melt-blown nonwoven industry.

    Introduction to the Main Functions of Short-Fiber Geotextiles and Standards for Judging Geotextile Quality

    Short-fiber geotextiles are generally more flexible in slope protection projects, facilitating construction and maintenance with minimal impact on the environment. They are usually applied in dike and waterway projects of large rivers and lakes where there is no wave load.

    Introduction to the Composition, Specifications and Application Standards of Non-woven Fabrics for Masks - Huaye Lecture Hall

    Today, we will popularize the classification of commonly used masks on the market and the composition of non-woven fabrics in masks. First of all, the commonly used masks on the market are divided into two major categories: flat masks and three-dimensional masks. Below, we will find two actual pictures to show you.

    What Is the Flame-Retardant Principle of Flame-Retardant Nonwoven Fabrics?

    When it comes to flame-retardant nonwoven fabrics, many people are familiar with them. This is because with the development of the nonwoven fabric industry, nonwoven fabrics have become common products in our daily lives. For instance, the thermal insulation covers used in agricultural vegetable greenhouses are mainly made of needle-punched nonwoven fabrics. In winter, greenhouse insulation materials have shifted from straw to thermal insulation covers; however, these covers have a drawback: poor fire resistance. The emergence of flame-retardant nonwoven fabrics has effectively solved the fire hazard problem in vegetable greenhouses and general greenhouses. Below, I will explain the flame-retardant principle of flame-retardant nonwoven fabrics (Note: The original text contained a suspected typo "耐磨性燃烧原理," which has been corrected to "flame-retardant principle" based on context). Compared with other nonwoven fabrics, flame-retardant nonwoven fabrics have higher high-temperature resistance, a higher melting point, and better sealing performance.
