Spunbond nonwovens are ideal for hygiene product sector. Characterized by our nonwovens’ superior softness, excellent fibres distribution, balanced tensile and elongation features, optimal physiological properties, our hydrophobic and hydrophilic SS, SSS and BICO spunbond nonwovens are used in key components of baby diaper, adult incontinence briefs and pants, sanitary napkins, panty liners and underpads, and more.
Spunbond nonwoven is a type of nonwoven made using a process where continuous filaments of polymer (like polypropylene, pp/pe) are spun and directly laid into a web-like structure. The web is then bonded to create a strong, lightweight, and durable fabric.
Our spunbond nonwoven fabrics are mainly used in baby diapers, feminine sanitary napkins, pantyliner, nursing pads, adult incontinence briefs and pants, we also call them disposable absorbent hygiene products.
These products make an important contribution to the quality of everyday life of millions of people.
Our SS, SSS and bi-component spunbond nonwovens are designed to meet different needs. All can be used in hygiene products where low basis weight, high performance and softness are essential, such as topsheet, backsheet, barrier leak cuff, core wrapping, waistband and closure systems.
Topsheet SSS spunbond nonwoven is hydrophilic, enabling efficient liquid penetration to the absorbent core while keeping the top sheet relatively dry to the touch. It is engineered for softness, breathability, and skin-friendliness, ensuring maximum comfort while maintaining functionality.
Backsheet SSS spunbond nonwoven is hydrophobic, normally laminated with PE film as a critical role in providing a barrier to liquid leakage, allows vapor to escape while offering a comfortable and breathable with a cloth-like texture, and good tensile strength to maintain integrity during use.
Core wrapping SSS spunbond nonwoven is hydrophilic and low basis weight, better tensile strength than carrier tissue. It helps maintain the integrity of the absorbent core, preventing superabsorbent polymer (SAP particles) or fluff pulp from migrating out of the core while allowing liquid to pass through efficiently.
Waistband SSS or BICO spunbond nonwoven is hydrophobic and soft, widely used in pull-up pants. It’s designed to provide excellent softness for the delicate skin, reducing irritation and ensuring comfort for extended wear, and breathable air circulation to maintain comfort around the waist area.
It is an integrated one-step process – from raw material to nonwoven, spinning continuous filaments directly from polymers and laying them into a web structure. This process is efficient, cost-effective, and versatile.
Leveraging our existing spun-bond technology platform, extensive expertise, and innovation approach, we have developed nonwoven with varying degrees of softness to meet the needs of diverse markets.
When properties like supreme silky softness and smooth touch are required, we utilize our bi-component spunbond technology. With this technology, the spunbond fibers are composed of polypropylene and polyethylene in shear or side-by-side configuration, where the polyethylene delivers enhanced softness and smooth touch characteristics.
We also offer a variety of embossed and apertured nonwovens, which make your product more functional, and differentiate it from others.
No matter which product you need, we work with a long list of general characteristics of our nonwovens.
It is a long way from resin to nonwoven in a spunbond process and attention to detail in every link of the chain is required.
Raw material preparation, 100% PP or PP/PE polymer resin and various additives like color masterbatch are used as the raw materials.
Extrusion, the raw materials are melted in an extruder at a specific temperature. The molten polymer is then pushed through spinnerets with thousands of tiny nozzles to create fine filaments.
Filament quenching, as the filaments are extruded, they are cooled rapidly using a steam of cool air. The solidifies the fibers.
Stretching/Drawing, the cooled filaments are stretched or drawn using high-speed airflow. This step increases the strength and reduces the diameter of the fibers, spunbond fibers typically have a diameter in the range of 13-17 μm (1.2-2.0 dtex).
Web formation, the drawn fibers are laid down on a moving conveyor belt to form a continuous web. The fibers can be randomly oriented (most common) or directionally laid for specific applications.
Thermal bonding, the web is thermo-bonded using heated rollers to form a final spunbond nonwoven, which involves: Passing the web through heated calender rollers that fuse the fibers together at points; Adjusting the temperature, pressure, and roller speed to control fabric properties like softness and strength.
Finishing and treatment, the bonded nonwoven fabric can be treated with surface or functional coatings such as hydrophilic finished for hygiene applications, hydrophobic treatment for water repellency, and antibacterial treatment for medical textiles.
Cutting and roll-up, The spunbond nonwoven fabric is scanned by cameras for quality control before being rolled onto shafts in large jumbo rolls, and subsequently slit into the required smaller width rolls and packed according to customer requirements.
Superior product quality is nothing but a good standard. It is reliability in every step of the process that is hard to come by.
We have the right technology and machinery, but it is responsible and quality-conscious employees in every link of the value chain that ensures our customers the high quality they expect in our products and services.
Continual improvements are necessary to exceed the expectations of our customers.
We have formalized our working processes, and nine inspection process. We have developed a system ensuring best in class quality assurance, product quality and quality logistics.
The result is accountability and traceability through every step of the production process – from raw material to final delivery.
We honour customer expectations with regards to our products and services and ensure compliance with relevant legislation and statutory requirements.
To strengthen our market position and enhance our competitiveness, we are committed to:
