What Are Stitch Bonded Nonwovens
Stitch bonded nonwovens are a special fabric. People do not weave or knit them in the usual way. Machines stitch or knit fibers and yarns through a mat of fibers. Needles help lock the fibers together. The finished fabric looks like it is knitted. It is made quickly and does not waste much material.
Stitch bonded nonwovens are fabrics made by stitching or knitting fibers and yarns through a mat of fibers. Needles interlock the fibers, so the fabric looks like it is knitted. The Textile Institute says this fabric has many parts. It has interlooped stitches running along the fabric. It can also have fiber webs or other fabrics mixed in.
Key Features of Stitch Bonded Nonwovens
You can tell stitch bonded nonwovens by their special features. These fabrics have strong surfaces and do not tear easily. The way they are made gives them strength in all directions. The stitching lines up the fibers, so the fabric can handle hard work.
Here is how the mechanical stitching process works:
- The machine puts the fiber web into the stitching area.
- Needles go through the web and pull yarns through the fibers.
- The machine makes stitches that hold the fibers together.
- The fabric moves forward and is collected at the end.
There are many types of machines for stitch bonding. Some common ones are:
- Arachne
- Maliwatt
- Malivlies
- Malimo
- Malipol
- Voltex
- Kunit
- Multiknit
Stitch bonded nonwovens have strong surfaces and do not tear easily. They are strong both up and down and side to side. The stitching lines up the fibers, making the fabric even stronger. You can use these fabrics for tough jobs.
How Stitch Bonded Nonwovens Differ from Other Nonwovens
You may wonder how stitch bonded nonwovens are different from other nonwovens. The main difference is how the fibers are held together. Stitch bonding uses needles and thread to make stitches that hold the fibers. This gives the fabric more strength and lets it bend.
Other nonwoven fabrics use different ways to bond fibers:
- Stitch Bonding: Uses needle and thread to make stitches that hold fibers together. This makes the fabric strong and flexible.
- Thermal Bonding: Melts thermoplastic fibers with heat to bond them. No stitching is used. This works for some special fibers.
- Chemical Bonding: Uses glue or chemicals to stick fibers together. There are many types of glue and ways to use them.
Stitch bonded nonwovens are special because they use a machine to stitch layers of fibers together. This makes a fabric you can use for many things. You often see these fabrics in furniture, shoes, and roofing. Other nonwovens may use heat or glue, but stitch bonded nonwovens use stitching to stay together.
How Stitch Bonded Nonwovens Are Made
Web Formation in Nonwoven Fabric
The first step is web forming. In this step, loose fibers are put into a thin sheet called a web. Many kinds of fibers can be used, even recycled ones. Using recycled fibers is good for the planet and saves materials.
Here are the main steps for web forming:
- Loose fibers are spread out into a flat layer. This layer is called the web.
- The web is treated to make it stronger and more stable.
Recycled fibers are often used in web forming. Some examples are:
- PET (recycled polyester)
- Polypropylene (PP)
- Jute
- Aramide fibers like Kevlar and Nomex
- Viscose
- Cotton
- Other recycled fibers
You can use one fiber or mix them together. This lets you change how the nonwoven fabric will act. The web forming step is important because it builds the base for the next steps.
Stitch Bonding Process Steps
After the web is made, the next step is stitch bonding. Machines stitch yarns through the web to lock the fibers together. This makes the fabric strong and bendy.
The stitch bonding process has these steps:
- The web goes into the stitchbonding machine.
- Needles move up and down to push yarns through the web.
- Support combs and guide bars hold the web in place.
- Stitches are made by lapping, closing, and knocking-over.
- The finished fabric is pulled away for take-up and finishing.
Needles and yarns work together to make chain-stitch seams. These seams keep the fibers in place and make the fabric strong. The needles and yarns move together to keep the web steady. This locks the fibers and helps the fabric keep its shape, even when pulled.
Different materials can also be used in the process. Films, papers, and foams are some examples. Needles go through these materials and add yarns. This makes hybrid fabrics that can be used for many things.
Stitching Techniques and Machines
There are different machines and ways to do stitch bonding. Each machine is made for special jobs.
Here is a table with some common machines:
| Machine Type | Features | Applications |
|---|---|---|
| BS1-V (Single Bar) | Works with loose or pre-sewn fiber mesh, many cloth feeding ways | Home decoration, hygiene, shoe material, clothing lining |
| Double Bars | Like single bar but works faster | Many textile uses |
Stitch bonding machines do stitching and bonding at the same time. They make strong and light fabrics. More people are using these machines because they work well and can do many things.
Different needle methods can make stitch bonded nonwovens last longer. The process uses needles and yarns to hold fibers tight. This makes the fabric strong and keeps it from stretching or tearing. You can use this fabric for many hard jobs.
Tip: When picking a machine or method, think about the fibers, the web, and what you want the fabric to do. This helps you get the best fabric for your needs.
Now you know how web forming, stitch bonding, and machine choice all fit together. These steps make a fabric that is strong, bendy, and ready for many uses.
Materials and Properties of Stitch Bonded Fabric
Common Fibers and Yarns in Non Woven Fabric
Non woven fabric uses many kinds of fibers and yarns. Makers pick fibers based on what the fabric will do. Here are some fibers you often see:
- Polyester
- Viscose (rayon)
- Nylon
- Microfiber
- Acrylic
- Cotton
- Bamboo fiber
Many companies use recycled fibers to help the planet. This saves resources and cuts down on waste. Stitch bonded fabric is made with a weaving machine. The machine stitches a web of fibers together. Extra yarns or fibers can be added to the web. This gives the fabric a special look and feel. You can see clear stitching and a unique texture in these fabrics.
Physical and Performance Properties
Non woven fabric is strong and lasts a long time. The stitching holds the web together and makes it tough. Different bonding methods change how the fabric acts. Look at the table below to see how each method works:
| Bonding Method | Key Properties |
|---|---|
| Needle Punching | Good tear resistance and lasts long because fibers are packed tight. |
| Thermal Bonding | Very strong in one way but can tear easier than needle-punched fabric. |
| Chemical Bonding | Can soak up more but might feel stiff. |
| Hydroentanglement | Makes fabric strong and bendy with great tear resistance, no glue or heat needed. |
Stitch bonded nonwoven fabric can be made for many jobs. You can use it for covers, medical things, or other uses. The fabric can also be made to resist water or fire.
