What Is SMS Nonwoven Fabric?
SMS is the abbreviation of Spunbond + Meltblown + Spunbond, referring to a three-layer composite nonwoven fabric. It is formed by laminating two outer spunbond nonwoven layers and one middle meltblown nonwoven layer through high-temperature hot rolling technology, without any weaving or knitting process.
Each layer undertakes independent core functions and complements each other to form an all-round high-performance material:
-
Outer Spunbond Layers: These two surface layers provide excellent tensile strength, tear resistance, and abrasion resistance. They make the fabric sturdy, durable, and not easy to deform or fluff during cutting, sewing, and use, adapting to various processing and usage scenarios.
-
Middle Meltblown Layer: As the core functional layer, it features ultra-fine fiber structure, dense pore distribution, and powerful filtration and barrier capabilities. It is the key to realizing the fabric’s anti-bacterial, anti-liquid, and anti-particle performance.
Different from single-layer nonwoven fabrics, the three-layer composite structure of SMS perfectly solves the contradiction between “protection performance” and “breathability”, avoiding the defects of poor air permeability of pure meltblown fabric and weak barrier of pure spunbond fabric.
Core Advantages & Key Performance Features
SMS nonwoven fabric has comprehensive superior properties after professional composite processing and special functional finishing, which is far better than ordinary nonwoven materials. Its core advantages are summarized as follows:
1. Outstanding Barrier & Filtration Performance
The dense meltblown core layer achieves a bacterial filtration efficiency of over 98%, which can effectively isolate bacteria, dust, fine particles, droplets, plasma, and alcohol liquid splashes. It meets AAMI Level 3-4 medical protection standards, providing reliable safety protection for high-risk hygiene scenarios. The fabric also has excellent hydrostatic pressure resistance (over 50cmH₂O), preventing liquid penetration effectively.
2. Balanced Breathability & Comfort
While ensuring strong barrier performance, SMS fabric maintains stable air and moisture permeability. It does not cause stuffiness, sweating, or skin discomfort during long-term wearing and use. The soft and smooth surface brings a skin-friendly touch, no irritation, no lint falling, and no static generation, greatly improving the user experience of finished products.
3. High Strength & Durability
Supported by double spunbond layers, the fabric has high tensile strength (≥30N/5cm) and excellent tear resistance. It is not easy to break or damage during wearing, operation, and processing, adapting to complex and rigorous use environments. The overall structure is stable, with no fiber shedding, ensuring the cleanliness of the use scene.
4. Multifunctional Customizable Performance
Our SMS nonwoven fabric can be customized with multiple functional treatments according to customer needs, including anti-static, anti-alcohol, anti-plasma, water repellent, hydrophilic, and antibacterial properties. It is non-toxic, tasteless, latex-free, and hypoallergenic, meeting global safety and hygiene standards.
5. Cost-Effective & Eco-Friendly
Made of high-quality polypropylene raw materials, SMS nonwoven fabric is lightweight, easy to process, and low in production cost compared with traditional woven protective fabrics. It is disposable, pollution-free, and degradable, conforming to modern environmental protection production concepts and global green industry trends.
Main Applications of SMS Nonwoven Fabric
Thanks to its comprehensive performance advantages, SMS nonwoven fabric is widely used in medical hygiene, daily sanitary products, industrial protection, and other fields, becoming an indispensable core material in multiple industries:
1. Medical & Healthcare Industry (Core Application)
It is the preferred material for high-grade medical protective supplies, including disposable surgical gowns, isolation gowns, medical protective suits, surgical drapes, medical bed sheets, and medical packaging materials. Its reliable anti-bacterial and anti-liquid barrier performance effectively reduces the risk of cross-infection in medical environments.
2. Daily Sanitary Products
Used for the surface layers and isolation layers of diapers, sanitary napkins, maternity pads, and pet pads. The hydrophilic and breathable version keeps the surface dry and comfortable, while the waterproof version effectively prevents liquid leakage, ensuring safety and hygiene for daily use.
3. Industrial Protection & Purification
Suitable for industrial protective clothing, dust-proof covers, equipment isolation layers, and air filtration materials. It can block industrial dust, fine particles, and chemical liquid splashes, and is widely used in electronics, pharmaceutical, chemical, and food processing clean workshops.
4. Other Scenarios
It can also be used for agricultural heat preservation and dust prevention, household cleaning cloths, hotel disposable bedding, and other scenarios, with strong market versatility.
