Differences Between Spunbond and Non-Woven Fabrics
Spunbond and Non-Woven Fabrics can be confusing when learning about them as textiles and the terms associated with them are not intuitive for those who do not manufacture fabric. They are essential fabrics used in a variety of industries, such as hygiene, agriculture, medical, and construction. If you are thinking about purchasing a spinner non-woven fabric machine or just interested in what they can be used for, then this guide will provide you with the major differences, uses, and how they are manufactured. Read more below.
Non-Woven Fabrics
Non-woven fabric refers to a type of fabric that is produced by bonding fibers together through various processes (including chemical, mechanical, or thermal bonding) without weaving or knitting the threads; instead, the fabric is made directly from the fibers created to form a completed fabric structure. This characteristic gives non-woven fabrics unique characteristics such as: lightweight, soft feel, breathable, durable, and places them in a number of products such as surgical masks, filters, agricultural coverings, and disposable hygiene products.
Spunbond Fabrics
Spunbond fabric is a type of non-woven sheet fabric that is manufactured through a process called spun bonding. During the spun bonding process, the thermoplastic polymer is melted and extruded through the Spinnerets, producing a continuous filament, which is deposited randomly onto a conveyor/transport belt. Once the filaments are on the belt, they are bonded to each other by heat and pressure, forming an even, consistent sheet of spun-bonded fabric. Common types of polymers for the manufacture of spunbond fabrics are Polypropylene (PP), Polyester (PET), and Polyethylene (PE).
Spunbonded fabrics have attributes such as high tensile strength, good porosity, reasonable price-to-performance ratio, and are used in the manufacture of many products, including medical gowns and masks, geotextiles (landscaping fabrics), and shopping bags.
Key Differences Between Spunbond and Non-Woven Fabric
Spunbonded fabrics are a type of nonwoven, but there are key differences between them:
- Production Processes: Spunbonding specifically refers to the process used to manufacture spunbonded fabric, while nonwoven fabrics are manufactured using more than one method (needlepunching, wet-laying, chemical bonding, etc.).
- Material Properties: Due to the nature of spunbonded fabrics being produced from continuous filament yarn, spunbonded fabrics typically have higher tensile strength and are more durable than most nonwoven fabrics. Nonwoven fabrics may also have a variety of textures, softness, and visual appearance depending upon the manufacturing process used to produce them.
- Applications: Spunbonded fabrics are typically selected for applications that require strength and durability, such as medical, agricultural, and packaging products. Other nonwoven products, such as those produced via meltblown processing, are selected for applications requiring filtration efficiency (e.g., air filters, N95 masks).
Manufacture of Spunbond Fabric
The manufacture of spunbonded fabric includes several advanced process steps that can be accomplished using a Spunbond Nonwoven Fabric Machine. Below is a recap of the details of the production of spunbond and non-woven fabrics:
- Melt Polymers: The production process begins when the resin (thermoplastics; typically polypropylene) is melted.
- Extrusion Process: Once the resin is moltenized, the form of continuous filaments is made by extrusion through spinnerets.
- Cooling Process: The filaments are cooled and solidified by air or some other cooling method.
- Web Formation Process: Once the filaments are continuous and cooled, they are placed on a conveyor belt in random or an aligned pattern to create the web.
- Bonding Process: The web is bonded (thermally, chemically, or mechanically) to create a single uniform sheet of spunbond fabric.
Overall, the entire production process is very efficient and thus, many manufacturers are moving to advanced machines for spunbond production. If you are looking to buy a spunbond non-woven fabric machine factory price, it is important to compare the options available to determine the production capacity, material compatibility, and energy efficiency.
Applications and Market Demand
Spunbond and non-woven fabrics are used in a variety of industries. Medical and sanitary products are reliant on spunbond materials for surgical gowns and masks that are comfortable, have excellent filtration, and are tear-resistant. Packaging, furniture, and agriculture also rely on spunbond because they are lightweight but strong materials.
There is tremendous growth in these industries and due to the increased awareness of hygiene since the pandemic, the demand for new and affordable spunbond non-woven fabric machine solutions continues to rise worldwide.
FAQ: Addressing Common QuestionsWhat is the most common material for producing spunbond fabrics?
The most commonly used polymers for producing spunbond materials are polypropylene, polyester, and polyethylene. Polypropylene is usually the polymer of choice due to its cost-effectiveness and the ability to produce fabrics with many different properties.
What is the difference between spunbond and meltblown?
They are both considered non-woven fabrics, however, they are made in different ways and used for different purposes. Spunbond has excellent strength and durability, while meltblown has fine fiber construction and is mainly used for filtering applications.
What should I consider when purchasing a spunbond non-woven fabric machine?
There are a variety of factors to consider, including production capacity, automation, material compatibility, energy efficiency, and marketplace reputation of suppliers. Additionally, comparing spunbond non-woven fabric machine factory prices will help in making a cost-effective decision.
Conclusion
To choose the correct material or manufacturing equipment for your specific needs, you must first understand the difference between spunbond and non-woven fabrics. Although spunbond is a subset of non-woven fabric due to its unique production method and excellent structural characteristics, the ongoing dependence by the industries on the many different types of spunbond fabrics will cause an increased demand for reliable spunbond non-woven fabric machines.
