ES non-woven fabric occupies a unique and important position in the non-woven fabric family. It has demonstrated strong application value in many fields due to its unique raw material composition, diverse production processes, and excellent performance.
Raw material composition: Unique two-component composite fibers
The core material of ES non-woven fabric is ES fiber, also known as “Ethylene Propylene Side By Side” in English, which is a type of polyolefin composite fiber. This type of fiber has a two-component skin core structure with distinct characteristic differences. Its cortex has a low melting point and a soft texture, while the core has a high melting point and strong strength. When ES fibers are subjected to heat treatment, the low melting point skin is melted by the heat, like a “glue”, bonding the fibers together to form a stable non-woven fabric structure. At the same time, the core layer maintains the fiber state, endowing the non-woven fabric with good flexibility and fluffiness, which is one of the key characteristics that distinguishes ES non-woven fabric from other types of non-woven fabrics. For example, when making insulation fillers, ES non-woven fabric with high fluffiness can effectively retain air, form a good insulation layer, and enhance the insulation effect; Its flexibility allows the filling material to better fit the human body or fill the space during use, improving comfort.
Production process: Diversified processes achieve diverse products
（1） Hot air bonding process
Hot air bonding is a common process in the production of ES non-woven fabrics. In this process, the ES fibers are first combed into a web, and then the hot air blown out by the drying equipment penetrates the web strongly. The heat of hot air causes the outer layer of ES fibers to melt and bond between fibers. The ES non-woven fabric produced by this process has high fluffiness, good elasticity, and extremely soft hand feel. Taking the production of baby diaper fabrics as an example, fluffy and soft ES non-woven fabric can provide gentle care for the delicate skin of babies, reducing friction and discomfort; Good elasticity ensures that the diaper can stretch and contract moderately with the baby’s movements during use, fitting snugly to the body.
（2） Hot rolling bonding process
The hot rolling bonding process achieves the bonding of ES fibers by heating and applying pressure to the rolling mill. In this process, heated rollers apply pressure to the fiber web to melt and bond the outer layer of ES fibers. Compared with the hot air bonding process, the ES non-woven fabric produced by hot rolling bonding has higher strength. When making filter materials, high-strength ES non-woven fabric can withstand the impact of fluids and the friction of particles, ensuring stable filtration process and extending service life.
In addition to the two main processes mentioned above, ES fibers are also suitable for various non-woven fabric processing methods such as needle punched, wet, air laid mesh, and water jet. This makes ES non-woven fabrics have rich diversity in product form and performance, which can meet the diverse needs of different fields.
Performance: Soft, breathable, and environmentally friendly
（1） Excellent physical performance
1. Softness and elasticity
ES non-woven fabric, with its fiber structure and bonding method, performs excellently in terms of softness and has an extremely soft hand feel, making it a great choice in the field of hygiene products that require extremely high softness. In products such as baby diapers and women’s sanitary napkins, soft ES non-woven fabric can effectively avoid irritation to the user’s skin and provide a comfortable user experience. At the same time, it also has excellent elasticity recovery ability, which can quickly restore its original state after stretching or squeezing. For example, when making reusable eco-friendly shopping bags, the elasticity of ES non-woven fabric can ensure that the bag maintains its shape and is not easily deformed after multiple loading of items.
2. Breathability and permeability
The fiber structure and fluffiness of ES non-woven fabric endow it with good breathability and permeability. In applications such as insulation fillers and hygiene products, good breathability can ensure air circulation, regulate temperature and humidity, and avoid users feeling stuffy and hot. When making the filter layer of a mask, ES non-woven fabric can effectively block particles such as droplets while ensuring smooth breathing for the wearer; Its permeability helps sanitary products absorb liquids, keep the surface dry, and improve product performance.
（2） Good chemical stability
Although the corrosion resistance of ES non-woven fabric is slightly inferior to some other materials in reinforced corrosive environments, it has good chemical stability in general environments. This allows it to be applied in many daily necessities and some industrial fields that require certain chemical stability. When making disposable tableware packaging, ES non-woven fabric can resist the erosion of substances such as oil and moisture in food, protecting tableware from contamination; In industrial dust cover applications, it can resist the chemical reactions of common pollutants in the air and maintain dust prevention effect.
（3） Environmental advantages
During the production process of ES non-woven fabric, fibers can be bonded to each other through thermal processing without the need for additional adhesives. This not only simplifies the production process, but also reduces the use of chemicals and lowers the potential harm to the environment. In today’s increasingly environmentally conscious society, the environmental characteristics of ES non-woven fabric make it more competitive in the market and favored by many consumers and enterprises who pursue green and environmentally friendly products.
Application field: Powerful assistant for multiple scenarios
（1） Medical and health field
In the field of healthcare, ES non-woven fabric is widely used. Its soft and skin friendly properties, as well as good breathability, make it an ideal material for products such as mask filter layers, surgical gown inner layers, and sanitary pads. In masks, ES non-woven fabric can effectively filter out small particles in the air while ensuring good breathability and improving the comfort of the wearer; The inner layer of the surgical gown is made of ES non-woven fabric, which can absorb the sweat of medical staff, keep the body dry, and will not cause irritation to the skin.
（2） Thermal insulation product field
The high fluffiness and strong warmth of ES non-woven fabric make it play an important role in insulation products such as cold clothing, bedding, and baby sleeping bags. It can effectively block heat loss and create a warm and comfortable environment for users. In the cold winter, anti cold clothing filled with ES non-woven fabric is lightweight and warm, allowing people to move freely during outdoor activities; The baby sleeping bag is filled with ES non-woven fabric, which can provide gentle warmth and care for the baby’s sleep.
（3） Household goods field
ES non-woven fabric can also be seen everywhere in daily life. Disposable tablecloths, napkins, and other commonly used household items are often made of ES non-woven fabric. Its softness and good water absorption allow the napkin to gently touch the skin during wiping, effectively absorbing moisture; Disposable tablecloths made of ES non-woven fabric are not only easy to clean, but also have certain waterproof properties, which can protect the desktop from stains and erosion.
（4） Field of filtration, sound insulation, and shock absorption materials
High density ES non-woven fabric hot melt adhesive products can be used to make filter materials, sound insulation materials, shock absorption materials, etc. In air purification equipment, ES non-woven fabric filter material can efficiently filter impurities such as dust and pollen in the air, improving air quality; In car interiors, ES non-woven soundproofing materials can effectively reduce interior noise and improve driving comfort; In the packaging of some precision instruments, ES non-woven shock-absorbing materials can cushion the vibration during transportation and protect the safety of the instruments.
In summary, ES non-woven fabric occupies an important position in the non-woven fabric market due to its unique raw materials, diverse processes, excellent performance, and wide applications. With the continuous advancement of technology, its performance is expected to be further optimized, and its application fields will continue to expand, bringing more convenience and value to people’s lives and production.
