If you are a beginner in the textile industry, you may have heard the term “Nonwoven fabric,” but you may wonder what is Nonwoven Fabric? Nonwoven is one of the most popular and unique quality fabrics in the textile industry. It is a versatile fabric that is made from fibers that are bonded together without weaving.
The manufacturing process of nonwovens involves various methods, including spun bond, spun lace, malt blow, and so on. It is used in multiple industries and applications due to its unique properties, such as high porosity, softness, durability, and low cost. This article is going to discuss everything about this nonwovens that you need to know.
What is Nonwoven Fabric?
Nonwoven fabric is which formed without forming and interlacing or intermeshing of fiber. non-woven textiles created using mechanical, chemical, or thermal techniques.
These fabrics consist of one or more layers of fibers and are flexible and porous. They are composed of sheet or web structures that are fused together by interlocking fibers or filaments. These flat fabrics are made by combining separate fibers or molten plastic or plastic film.
Nonwoven fabrics are made specifically for each use, whether for industrial or consumer use. These fabrics can be thin and light or sturdy and durable. High-performance goods can be delivered thanks to incorporating their unique qualities through the choice of raw materials, the employment of forming and bonding techniques, or the use of finalizing treatments.
What is Nonwoven Fabric Made of?
Nonwoven fabric is directly made from fiber without forming yarn. It is composed of fibers, that have been mechanically, chemically, or physically woven into a web. Instead of being woven or knitted, nonwoven fabrics are created from fibers that are glued together mechanically, chemically, or thermally.
Nonwovens are often made of viscose, polyethylene, polyester, and polypropylene, while cotton can be utilized to manufacture products with medical end-use.
Different Types of Nonwoven Fabric
Nonwoven Fabrics are available in different types, including spud-bond, spun-lace, melt-blow, Air-laid, and so on. Every kind of non-woven fabric has various features.
Let’s explore different types of nonwoven fabrics in details:
- Spun-Bond Nonwoven
- Spun-lace Nonwoven
- Melt-blown Nonwoven
- Air-laid Nonwoven
- Wet-laid Nonwoven
- Stitch-Bonded Nonwoven
1. Spun-Bond Nonwoven fabric
Manufacturing spunbond nonwoven fabrics involves extruding and stretching polymer to produce continuous filaments. These filaments are then interlaced through a melting and spinning procedure, producing a web of fibers. The fibers are strengthened and made more durable through the use of chemical, thermal, or mechanical bonding methods.
2. Spun-lace Nonwoven Fabric
Spun-lace non-woven fabric is made by entangling web fibers using high-pressure water jets. The process creates a uniform fabric with reinforced threads. Although not as durable and stable as other types of nonwoven fabrics, it is popular in making face masks, disposable surgical gowns, wet wipes, filters, etc.
3. Melt-blown Nonwoven Fabric
The melt-blown non-woven fabric also uses polymers to manufacture this fabric. However, it is passed through a straight-line die to create long, thin fibers instead. The threads are cooled using hot air, and the resulting fiber webs are then gathered on an accumulation screen. Here, the fibers come together to create the nonwoven fabric.
4. Air-laid Nonwoven Fabric
The procedure used for producing air-laid nonwovens involves opening the fluff pulp as well as suspending the fibers in the air in a formation process. Following the deposition of the threads on the forming screen, an adhesive is used to connect the batting, as well as the fibers are then dried.
5. Wet-laid Nonwoven Fabric
The production of a wet non-woven fabric involves many phases. The raw material, which consists of fibers, is first submerged in water to separate into a single fiber. The addition of various fibrous raw materials creates a slurry of fibrous suspension next. The mesh is then put in the wet condition it was treated in to make the fabric after the slurry was treated in a mesh-forming device.
6. Stitch-Bonded Nonwoven Fabric
Stitch-Bonded Nonwoven Fabric is another popular dry non-woven fabric. This fabric uses a wrap-knitted loop structure, which gives the yarn layer, fibers web, and the additional layers utilized in its production strength and structure. The fabric’s structure is strengthened by the mixing of multiple layers.
