From raw PP materials to finished roll production, how is a piece of meltblown fabric made?

If you open an ordinary medical mask, you will see a three-layer structure. The inner and outer layers feel soft and fluffy, while the middle layer feels a bit hard and has a paper-like texture. When illuminated, there are faint fine fiber patterns, this is the Meltblown fabric. It is not responsible for keeping warm or shaping, but rather performs a delicate task: blocking the particles that want to enter your mouth and nose.Meltblown fabric belongs to meltblown nonwoven materials. The raw material is mainly polypropylene, and it is formed by melt extrusion and high-speed hot air flow stretching to create a random interlaced ultra-fine fiber network structure. It is also a widely used functional material in the fields of protection and filtration. Lianyungang Baidi Industrial Co., Ltd. has been deeply engaged in the nonwoven material field for many years and can supply various specifications of meltblown fabric, meeting the filtering requirements of different customers.The fibers of meltblown fabric are ridiculously fine. The fibers of ordinary spunbond fabric have a diameter of 10 to 50 microns, while the fibers of meltblown fabric usually fall within the range of a few microns or even finer. These fibers are randomly laid out to form a net, with the pores being cut to be small and dense. But merely having "fine pores" is not enough. What truly enables it to have interception ability is a process called static electrification treatment. Polypropylene is an insulating material by itself, and after static electrification, the surface of the fibers can retain charges for a long time. When charged fibers encounter particles in the air, the static electricity will actively pull them towards the fiber surface, rather than simply waiting for the particles to collide on their own. This "suction" ability is particularly effective for fine particles, and it does not increase breathing resistance.The application scenarios cover medical protection, air purification, industrial fluid filtration, etc. In protective products, meltblown fabric serves as the intermediate filtering layer, bearing the core blocking function; in the purification industry, it can be used for new air filter screens, dust removal filter materials; in industrial scenarios, it is also often used as liquid filtration, oil absorption, sound insulation, and heat insulation materials, with a wide range of applications.The process of Meltblown fabric products of Lianyungang Baidi Industrial Co., Ltd.: PP raw material → feeding and drying → screw melt extrusion → meltblown die head → hot air stretching → laying and forming → static electrification treatment → winding and cutting → finished packagingBoulder was founded in 2007, with its headquarters located in Los Angeles, USA.

Healthcare, agriculture, packaging, home furnishing: The multi-scenario penetration of spunbond non-woven fabric

In the application fields of nonwoven materials, spunbond nonwoven fabric, due to its mature production process and wide range of applicable materials, is applied in various scenarios such as healthcare, packaging, agriculture, home furnishing, and industrial materials. Different from traditional textile materials, spunbond nonwoven fabric does not need to go through traditional spinning and weaving processes. Instead, it forms sheet like materials with certain strength and structural stability through processes such as spinning, net formation, and reinforcement.Production characteristics of spunbond nonwoven fabricThe production of spunbond fabric usually uses high molecular materials such as polypropylene as the main raw material. It forms continuous long fibers through melt extrusion, and then undergoes stretching, laying of the net, and reinforcement by heat rolling, needle punching, or other methods. The entire production process has continuous characteristics and can adjust the fineness, weight, width, and material properties of fibers according to product requirements.In actual production, factors such as raw material ratio, melt temperature, spinning state, stretching conditions, and net uniformity will all affect the quality of the finished product. Therefore, for different application needs, it is necessary to make reasonable adjustments based on production equipment and process conditions.Product performance and application are interrelatedSpunbond nonwoven fabric has good flexibility and certain tensile strength, and also has the characteristics of breathability and lightness. By adjusting the production formula and processing methods, corresponding weights, thicknesses, and hand feel can be designed for different uses.In the healthcare field, it can be used for some protective products and hygiene materials; in the agricultural field, it can be used for crop covering and protection in scenarios; in the packaging industry, it can be used for shopping bags and packaging materials; in home and daily use products, it can also be processed into different forms of materials according to actual needs.As the application scope of nonwoven materials continues to expand, spunbond nonwoven fabric is also developing towards functional specialization and diversified applications. For production enterprises, adjusting product specifications and processing methods according to the usage requirements of different customers can help the materials better match actual application scenarios and provide a stable material foundation for subsequent processing.Boulder was founded in 2007, with its headquarters located in Los Angeles, USA.

What Makes Medical Nonwovens Antistatic — and Why It Matters

In daily life, non-woven fabrics can be found everywhere, from medical masks, protective suits to shopping bags and cleaning cloths. They have integrated into every aspect of our lives. Many observant friends will notice that certain non-woven products do not easily attract dust or do not exhibit the crackling static discharge phenomenon during use. So, where does the anti-static ability of non-woven fabrics come from?Firstly, we need to understand the principle of static electricity generation. When two different materials come into contact and rub against each other, electrons will transfer, causing an uneven distribution of electric charges on the surfaces of the objects, thereby forming static electricity. For traditional synthetic fibers (such as polyester and polypropylene), they are insulating materials with extremely high resistivity. The friction-generated charges are difficult to release and tend to accumulate, leading to high-voltage static electricity. This not only attracts dust and affects the appearance of the products, but also poses safety risks in electronic manufacturing, flammable and explosive environments, and even potentially causes accidents.However, non-woven fabrics can effectively address this issue due to their special fiber structure and manufacturing process. Non-woven fabrics are not produced through weaving or knitting but are formed by physically or chemically bonding fibers together. This porous, loose network structure brings two direct benefits:Firstly, it increases the friction contact area and the surface area of air contact of the fibers. After the electric charge is generated, it can quickly disperse to a larger surface area, reducing the local electric charge density and thus weakening the static phenomenon.Secondly, and more importantly, non-woven fabrics are often treated with anti-static agents or mixed with conductive fibers during production. The former is usually a hydrophilic surfactant that can absorb trace amounts of moisture in the air, forming a conductive film on the fiber surface. This film provides a channel for the dispersion of the generated charges, allowing them to be quickly conducted to the outside or neutralized, thereby avoiding the accumulation of static electricity.Unlike post-treatment methods, some high-quality non-woven fabrics also adopt the technology of blending conductive materials during the spinning stage, such as adding carbon nanotubes or metal oxide powders to the fibers, making the fibers themselves conductive. This method not only provides long-lasting effects but is also less affected by environmental humidity, suitable for industrial packaging and electronic component protection in industries with strict requirements for static control.Furthermore, the hygroscopicity of the fibers plays a crucial role. Some non-woven fabrics are mixed with materials with high hygroscopicity, such as viscose fibers. When the environmental humidity is moderate, the water molecules adsorbed on the fiber surface can form a continuous conductive film, allowing the static charges to dissipate. Therefore, non-woven fabrics based on surfactant-type anti-static agents show significant differences in anti-static performance in humid southern environments and dry northern environments.In the medical nonwoven fabric field, the demand for anti-static properties is particularly urgent. In operating rooms, static discharge may interfere with precision medical equipment, ignite flammable anesthetic gases, and even damage medical staff and patients. Therefore, products such as medical protective suits and surgical gowns have clear national standards and industry regulations for anti-static performance. The anti-static solutions for medical non-woven fabrics are usually more systematic: on the one hand, a multi-layer composite structure of SMS (spunbond-meltblown-spunbond) is adopted, using the fine fiber network of the meltblown layer to enhance the ability to disperse charges; on the other hand, anti-static agents are introduced during spinning or post-treatment processes to reduce the surface resistance to a safe range. In recent years, new technologies such as biomimetic anchoring have also been used to stably fix conductive materials like graphene on polypropylene fibers, forming a persistent anti-static functional layer, balancing the waterproof and moisture-permeable properties of protective suits with long-lasting anti-static performance. The evolution of these technical paths reflects that the requirements for anti-static properties of medical nonwoven fabrics are moving from "short-term effectiveness" to "long-term stability", and from a single function to a combination of barrier, antibacterial and anti-static properties.Boulder was founded in 2007, with its headquarters located in Los Angeles, USA.

They look the same, but perform worlds apart—is the nonwoven fabric in your hands hydrophilic or hydrophobic?

When it comes to nonwoven fabrics, many people assume they all look alike. In reality, despite their similar thin appearance, there are significant differences in the user experience between hydrophilic types and standard types. To understand the distinction, we can look at the following aspects:Nonwoven products are ubiquitous in daily life, yet many people fail to notice that materials which appear similar can actually differ vastly in function. The core difference between hydrophilic nonwoven fabrics and standard nonwoven fabrics lies in their diametrically opposed interaction with water.1. Distinctly different "attitudes" toward liquidsThis is the fundamental difference between the two. Standard nonwoven fabrics are typically made from polypropylene (PP). As a nonpolar material, PP lacks the hydrophilic groups on its molecular chains necessary to bond with water and possesses low surface energy. Consequently, water droplets bead up and roll off rather than penetrating the material. In contrast, hydrophilic nonwoven fabrics undergo a hydrophilic treatment that increases fiber surface energy; upon contact, liquid rapidly wets and spreads across the surface, channeling downward through the capillary pathways between fibers. The industry often uses "contact angle" as a metric: standard water repellent fabrics exhibit a high contact angle, whereas hydrophilic fabrics maintain a low contact angle, resulting in significantly faster penetration.2. An additional "hydrophilic" step in productionThe production of standard nonwoven fabrics is essentially complete after web formation via processes such as spunbonding, thermal bonding, or hydroentanglement. Hydrophilic nonwoven fabrics, however, require the addition of hydrophilic masterbatch during production or the application of a hydrophilic agent during the finishing stage—using methods like dipping, padding, or spraying. Hydrophilic agent molecules feature both lipophilic (oil attracting) and hydrophilic (water attracting) ends; the lipophilic end adheres to the fiber while the hydrophilic end faces outward, creating a stable hydrophilic layer. This method offers manageable costs and is currently the most common practice.3. Distinct performance characteristics and applicationsHydrophilic non woven fabrics excel at rapid liquid penetration and wicking. They facilitate the quick transfer of liquid from the surface layer to the absorbent core, thereby reducing the sensation of dampness caused by surface residue, all while maintaining softness and breathability. Consequently, hydrophilic nonwoven fabrics are the preferred choice for components such as the topsheets and acquisition/distribution layers of diapers and sanitary pads, as well as for wet wipes, medical dressings, and facial mask substrates. The strengths of standard nonwoven fabrics lie in their barrier and protective properties; they are resistant to liquid penetration and—given appropriate hydrostatic pressure ratings—can serve as effective barriers. They are particularly well suited for applications such as shopping bags, packaging materials, the outer layers of protective suits and surgical gowns, mask exteriors, and agricultural coverings.In summary, while hydrophilic nonwoven fabrics and standard nonwoven fabrics belong to the same category of materials, distinct processing techniques render one hydrophilic and the other water repellent. This distinction is not a matter of superior or inferior quality, but rather a result of functional design tailored to specific uses; together, they broaden the range of applications for nonwoven fabrics in modern life.Boulder was founded in 2007, with its headquarters located in Los Angeles, USA.

Whether you drive or ride in a car, you know there's a significant amount of noise inside. This includes engine noise, tire noise from road friction, noise from airflow at high speeds, and other noises generated by the vehicle itself. The sources of various noises are: engine noise originates from its own rotational speed, while resonance noise comes from the refraction and overlap of sound within the vehicle body.As autumn arrives and the weather cools, the temperature difference between the inside and outside of the vehicle increases, making noise perception more noticeable. Automotive sound-absorbing cotton, a commonly used material for sound optimization, is widely used in car doors, hoods, headliners, wheel arches, etc., effectively reducing wind noise, tire noise, and resonance noises inside the car. For manufacturers who directly purchase materials, judging the quality of sound-absorbing cotton is a crucial step in product selection.First, we need to understand, what is Automotive sound-absorbing cotton?Automotive sound-absorbing cotton: When noise penetrates sound-absorbing cotton, sound waves are constantly reflected and folded between the densely packed fibers inside the cotton, forcing air molecules to move violently, and the sound energy is forced to be converted into heat energy and dissipated.Automotive sound-absorbing cotton product process: PP meltblown fibers are laminated within a PET base fabric and then solidified using hot air to create a high-loft, fluffy cotton.Applications of automotive sound-absorbing cotton: Door interior panels (to combat wind noise and environmental noise), wheel covers/fender linings (to combat tire noise, road noise, and gravel impact noise), engine hood (to combat engine noise). Automotive sound-absorbing cotton specifications, installation methods, material differences, noise reduction effects, and manufacturers are all relevant.The noise reduction effect of sound-absorbing cotton is closely related to its material density, thickness, and bonding method. When purchasing in bulk, it is recommended to understand: Does the supplier have a stable quality control process? Can they provide customized thickness, adhesive backing, or lamination solutions to meet customer needs? Stable process control capabilities are the foundation for ensuring consistent quality between batches.If you have any Automotive sound-absorbing cotton purchasing needs or technical questions, please contact Lianyungang Boulder Industrial Co., Ltd. for discussion.

Autumn/Winter Purchasing Reminder: Understand These Basic Concepts of Antistatic Nonwoven Fabrics First!

As autumn arrives and the weather becomes drier, static electricity problems begin to emerge. In daily life, static electricity is generated by the peeling of plastic films and the friction of synthetic fiber clothing. Non-woven fabrics are mostly made of polymer materials, which are good insulators. The charges generated by friction are not easily discharged and accumulate on the material surface. This accumulation is more pronounced in dry environments.Static electricity causes many problems: it attracts dust, affecting cleanliness; it causes electric shocks during use; and it can even pose a safety hazard in certain special work scenarios. Therefore, it is practically necessary to require anti-static properties in some product applications.Two Types of Antistatic Nonwoven Fabric：Anti-static non-woven fabrics on the market can be broadly divided into two categories based on their implementation method:Internal Additive Type: The anti-static agent is mixed into the polymer during the melt spinning stage of the raw material. The advantage of this method is that the anti-static component is evenly distributed inside and on the surface of each fiber, resulting in a longer-lasting effect that is less prone to attenuation due to friction and washing. It is suitable for products with high requirements for anti-static lifespan.Post-treatment Type: The anti-static agent is sprayed or impregnated onto the surface of the finished non-woven fabric. The process is relatively simple and the cost is low, but the antistatic components mainly adhere to the surface, and the effect may weaken after repeated friction or prolonged placement. It is suitable for short-term use or scenarios where durability is not a primary concern.Therefore, when purchasing, it's advisable to specifically ask: How does this product perform in the dry autumn and winter seasons? Professional suppliers will usually provide a clear explanation. For specific needs or technical questions, please contact Lianyungang Boulder Industrial Co., Ltd. for discussion.Antistatic Nonwoven Fabric: By adding antistatic masterbatch or antistatic oil, static accumulation can be effectively reduced, preventing dust attraction and minimizing electrostatic discharge, improving the safety of clean environments, and enhancing wearing comfort.Antistatic Nonwoven Fabric Product Process:Raw Material Modification: PP raw material → Addition of antistatic masterbatch → High-temperature melt extrusion → Spinning → Cooling/hot air drawing → Web forming → Hot rolling reinforcement → WindingOnline Antistatic Impregnation Treatment: PP raw material → High-temperature melt extrusion → Spinning → Cooling/hot air drawing → Web forming → Hot rolling reinforcement → Functional additives and antistatic oiling → Drying and setting → WindingApplications of Antistatic Nonwoven Fabric: Protective clothing, cleanroom garments, medical packaging, surgical gowns, isolation gowns, etc.

When purchasing Punched non-woven fabric in the fall, pay attention to these details!

With the start of the school season, downstream manufacturers of hygiene products and baby care products are entering their peak production season. As a surface material, the Punched non-woven fabric's pore design and quality stability directly affect the user experience of the final product.High-quality Punched non-woven fabric should have clear, regular, and uniformly sized pores, arranged evenly and orderly, without obvious deformation or adhesion. The width of the "bridge" (the solid portion between adjacent pores) should be basically consistent; uneven width will lead to unstable liquid seepage rates. If inconsistent pore sizes, burrs on the edges, or poor welding are found, it is necessary to be wary of potential equipment or process problems.After sample approval, bulk purchases require close monitoring of the production process. It is recommended to inquire with the supplier about: the maintenance cycle of the perforation mold; whether the pore diameter and spacing are monitored online during production; and whether the sample retention and testing records for each batch are complete. The precision and maintenance level of the mold directly determine the consistency and lifespan of the product.The selection of Punched non-woven fabric is related to the dryness and comfort of the final product. Understanding the above points will help make more informed decisions during procurement. If you have any purchasing needs or technical questions regarding perforated nonwoven fabrics, please feel free to contact Lianyungang Baide Industrial Co., Ltd.Lianyungang Boulder Industrial Co., Ltd.'s perforated nonwoven fabrics are functional materials that form regular or irregular microporous structures on the surface of nonwoven fabrics through processes such as mechanical processing, hot pressing, hydroentangling, or needle rollers.
