SMS Non-Woven Fabric: Characteristics, Applications, and Advantages Explained in 2023

SMS non-woven fabric, also known as Spunbond Meltblown Spunbond, is a versatile material that finds its application in various industries. This fabric is made up of layers of spun-bond polypropylene, melt-blown polypropylene, and spun-bond polypropylene again, hence the name SMS. Its unique combination of properties makes it suitable for a wide range of applications. This article will explore the characteristics, uses, and advantages of SMS non-woven fabric.

Introduction

SMS non-woven fabric is a type of engineered fabric that is manufactured using a specialized process. It offers a unique combination of strength, durability, and breathability, making it suitable for a wide range of applications. Whether you’re in the medical, automotive, or hygiene industry, SMS non-woven fabric has several advantages that set it apart from other materials.

What is SMS non-woven fabric?

SMS non-woven fabric is composed of three layers of polypropylene. The first and third layers are made through spun bonding, where the polypropylene fibers are spun and bonded together. The middle layer is created using melt-blown technology, where the fibers are melted and blown to form a fine web. Combining these layers provides unique properties to the fabric, including high strength, barrier protection, and breathability.

Manufacturing process

The manufacturing process of SMS non-woven fabric involves several steps:

1. Spunbonding: In this step, the polypropylene fibers are extruded, cooled, and stretched to form a continuous web. The fibers are then bonded together using heat and pressure.
2. Melt Blowing: In the next step, the melt-blown technology is used to create the middle layer. The polypropylene resin is melted and extruded through small nozzles, forming microfibers. These microfibers are then blown by hot air onto a conveyor belt, creating a fine web.
3. Spunbonding (again): The final step involves another round of spun bonding to add the third layer. The process is similar to the initial spun bonding step, where the fibers are bonded together to form a stable fabric.

Characteristics of SMS non-woven fabric

SMS non-woven fabric offers several key characteristics:

• Strength: SMS fabric is known for its high tensile strength, making it suitable for applications that require durability and resistance to tearing.
• Barrier protection: The middle meltblown layer acts as a barrier against liquids, bacteria, and other contaminants. It provides excellent filtration and prevents the passage of particles.
• Breathability: Despite its barrier properties, SMS fabric allows air and moisture vapor to pass through, making it comfortable to wear for extended periods.
• Softness: SMS fabric has a soft texture, ensuring comfort and minimizing skin irritation.

Applications of SMS non-woven fabric

The versatility of SMS non-woven fabric makes it suitable for various applications, including:

1. Medical and healthcare: SMS fabric is widely used in surgical gowns, drapes, masks, and other medical protective clothing. It’s barrier properties and breathability make it ideal for maintaining a sterile environment while providing comfort to healthcare professionals.
2. Hygiene products: SMS fabric is used in diapers, feminine hygiene products, and adult incontinence products. It provides absorbency, breathability, and softness, ensuring comfort and protection.
3. Automotive industry: SMS fabric is used in car interiors, seat covers, and headliners. Its durability, resistance to abrasion, and easy cleaning make it a popular choice for automotive applications.
4. Agriculture: SMS fabric is used in crop covers, nursery bags, and plant protection. It helps in regulating temperature, protecting plants from pests, and providing a conducive environment for growth.

Advantages of SMS non-woven fabric

There are several advantages of using SMS non-woven fabric:

1. Lightweight: SMS fabric is lightweight, making it easy to handle and comfortable to wear.
2. Cost-effective: SMS fabric offers a cost-effective solution compared to other materials with similar properties.
3. Breathable: The fabric allows air and moisture vapor to pass through, reducing the risk of heat buildup and promoting comfort.
4. Excellent barrier protection: SMS fabric provides a high level of barrier protection against liquids, bacteria, and particles.
5. Versatile: SMS fabric can be tailored to meet specific requirements and applications, making it a versatile material.

How to choose the right SMS non-woven fabric?

When choosing SMS non-woven fabric, consider the following factors:

• Application: Identify the specific requirements of your application, such as barrier protection, breathability, or softness.
• Weight and thickness: Different applications require different weights and thicknesses of SMS fabric. Determine the appropriate weight and thickness based on your needs.
• Regulatory compliance: Ensure that the SMS fabric meets the necessary regulatory standards for your industry, such as medical certifications or automotive specifications.
