Non-Woven Fabric Manufacturing: Details Discussion
What is Non-Woven Fabric?
Non-woven fabric is a web or sheet which is produced by using natural or man-made fibers or filaments or recycled fibers that have not been converted into yarns. Finally, these are bonding by following different methods to form a non-woven fabric. It may also have other names such as shaped fabrics or yarn free fabrics. In this article, I have presented the total process flow chart of nonwoven fabric manufacturing.
There are so many uses of non-woven fabrics in our daily life such as in clothing, civil engineering, furnishing, manufacturing factories, kitchens, cars, hospitals, etc.
Some special types of non-woven fabrics are agrotech, build tech, medi tech, mobi tech, pack tech, cloth tech, geo-tech, oeko tech, home tech, pro-tech, etc.
Types of Non-Woven Fabric Manufacturing Process:
There are mainly four types of the process followed to produce non-woven fabrics. Those are-
- Spun bond process,
- Melt blown process,
- Water jet process,
- Needle punched process.
Non-Woven Fabric Manufacturing Process Flow Chart:
The below process has to maintain during non-woven fabric manufacturing in the textile industry:
Processing of fiber (Man-made, natural, or recycled)
Dyeing (If necessary)
Laying (Dry laying, wet laying, spin laying)
Bonding (Mechanical, thermal, chemical, stitch bonding)
Raw non-woven fabric
Finished non-woven fabric
Methods of Non-Woven Fabric Finishing Process:
There are two types of finishing methods for non-woven fabric. Those are in the below:
1. Dry finishing methods:
2. Wet finishing methods:
- Anti-static finishing,
- Hygiene finishing,
- Dust bonding treatment,
- Absorbent and repellant finishes (Oil, static, water, etc.).
What Types of Fiber Used in Non Woven Fabric Manufacturing?
The following fibers (Natural, man-made, and natural fibers) are widely used in the non-woven fabric manufacturing process.
- Bi-component fibers,
- Recycled fibers.
