In the current era of rapid development of the medical health industry, medical nonwoven fabrics, as the core material for disposable medical supplies and infection prevention, are seeing an increasingly rich product range. From daily protection to complex surgeries, nonwoven fabric materials, with their characteristics of breathability, antibacterial properties, and softness, play an indispensable role in medical scenarios. As a medical nonwoven fabric manufacturing enterprise based in Lianyungang, Lianyungang Bode Industrial Co., Ltd. has built a product matrix covering multiple scenarios based on the needs of the medical and hygiene fields.The product range of medical nonwoven fabric products is quite extensive. In terms of infection prevention, the inner and outer layers of disposable medical masks and surgical masks often use nonwoven fabric materials, balancing the functions of skin friendly breathability and splash prevention. In the fields of surgery and wound care, products such as nonwoven fabric sheets, imaging non woven fabric sheets, and imaging nonwoven fabric strips are made using water jet or spunbonding processes, with good liquid absorption performance. Some products with embedded barium wires can be used for X ray imaging, providing auxiliary monitoring means during the surgical process. Additionally, medical absorbent pads and care pads achieve anti leakage and rapid penetration through a multi layer composite structure, suitable for surgical mattresses and post operative care scenarios. The foundation of these products all relies on the performance support of upstream medical nonwoven fabric rolls.Surgical protection nonwoven fabric products are an important component, covering surgical gowns, isolation gowns, surgical sheets, surgical towels, medical round caps, medical shoe covers, and sleeves. The products are functional post processed to effectively prevent body fluid splashing and reduce the risk of cross infection. They balance the requirements for protection while also considering mechanical strength and wear comfort, suitable for various clinical surgical operation environments.Sterilization packaging nonwoven fabric is a commonly used base material in the sterilization supply process, mainly used for sterilizing various diagnostic and surgical instruments. The material has a stable microporous barrier structure, which can adapt to mainstream sterilization methods such as ethylene oxide and high pressure steam, ensuring the smooth penetration of sterilization media, maintaining the sterile state of the instruments after the sterilization cycle, and meeting the usage standards of hospital sterilization centers.Wound and care nonwoven fabrics include water jet dressing base materials, medical wiping cloths, medical inspection pads, and absorbent care pad sheets. The water jet nonwoven fabric fibers are soft, low in fluff, and have good skin friendly properties, suitable for direct contact with the skin and wounds; medical wiping cloths have balanced liquid absorption performance and are mostly used for cleaning diagnostic equipment and operation tables; composite pad sheets are combined with a leak proof membrane structure, absorbing liquids while preventing leakage, suitable for clinical examinations, bed rest care, and other scenarios.At the same time, medical nonwoven fabrics can also be processed into filter materials for masks, medical aprons, and disposable hospital bed sheets, with functional attributes such as hydrophilicity, hydrophobicity, and anti static properties that can be adjusted according to customer requirements. Lianyungang Bode Industrial can customize the weight, specifications, and functional formula according to customer needs, strictly control the cleanliness of the production environment, implement the entire process inspection and testing to ensure that the product indicators comply with industry related standards.Boulder was founded in 2007, with its headquarters located in Los Angeles, USA.

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.

As autumn progresses, the climate becomes drier and the air humidity decreases. Daily activities such as clothing rubbing and item handling are more likely to generate static electricity. Static electricity may cause clothing to stick together, dust to adhere, or even cause minor electric shocks, causing inconvenience. Antistatic nonwoven fabric can help reduce static electricity accumulation through material design, providing support for related products and application scenarios.Antistatic nonwoven fabric usually improves the material's surface charge dissipation ability through fiber raw materials, production processes, or posttreatment methods. Compared to ordinary nonwoven fabric, this type of material helps reduce static electricity accumulation and alleviates the phenomenon of fine dust adhering to the fabric surface. It can be used in protective products, packaging materials, cleaning supplies, and some industrial scenarios, and the specific application depends on the product structure and usage environment.The antistatic nonwoven fabric produced by Lianyungang Boulder Industrial Co., Ltd. is produced through a special modification process, constructing chargedischarging channels within the material. When static electricity is generated through friction, it can slowly release the accumulated charges on the surface, preventing the continuous accumulation of charges. This characteristic precisely suits the characteristics of the autumn season with dry and low moisture content, where static electricity is not easily dissipated naturally.In clean and medical hygiene scenarios, antistatic nonwoven fabric can reduce the static adsorption effect. Ordinary nonwoven fabric is prone to adsorbing floating dust and particles in the autumn dry environment. The antistatic nonwoven fabric produced by Lianyungang Boulder Industrial Co., Ltd. can reduce the material's dust absorption ability, maintain surface cleanliness, reduce dust adhesion, and be suitable for protective fabrics, clean packaging, bed sheets, etc., reducing the risk of dust pollution and ensuring a clean and stable usage environment.In the industrial production field, the risk of static electricity in autumn cannot be ignored. In electronic workshops, powder processing, etc., static discharge may affect precision components and also pose a potential risk of igniting flammable materials. Antistatic nonwoven fabric is often used as dustfree wiping cloth, isolation layer, protective fabric base material, and continuously discharges static electricity, alleviating the various impacts caused by static electricity accumulation, helping to maintain the stability of the workshop production environment, and reducing various problems caused by static electricity. Lianyungang Boulder Industrial Co., Ltd. can provide antistatic nonwoven fabric base materials suitable for different scenarios according to the actual working conditions of customers.Antistatic nonwoven fabric production process:Raw material modification: PP raw material → Add antistatic masterbatch → Hightemperature melting extrusion → Spinning → Cooling / Hot air drawing → Laying net forming → Hot rolling reinforcement → Rolling upOnline immersion antistatic treatment: PP raw material → Hightemperature melting extrusion → Spinning → Cooling / Hot air drawing → Laying net forming → Hot rolling reinforcement → Functional additive antistatic oil → Drying and shaping → Rolling upApplication directions of antstatic nonwoven fabric: protective clothing, clean suits, medical packaging, surgical gowns, isolation suits, etc.Boulder was founded in 2007, with its headquarters located in Los Angeles, USA.

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.

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.
