Nonwoven fibers are the main constituent of nonwoven fabric products. In the geotextile industry, nonwoven production is one of the fastest-growing segments, and nonwoven fibers are the basic structural elements that make up a nonwoven fabric instead of yarns and threads.
The choice of a nonwoven fiber adopted usually determines the quality and properties of nonwoven fabrics. It is because the characteristics (diameter, length, tensile strength) of the nonwoven fiber you use will always influence the processing performance of the nonwoven fabric product. You can employ ALL types of nonwoven fibers in nonwoven production based on how easy it is to proceed and cost-effectiveness.
The most commonly used fibers are;
Natural fibers: like cotton, wool, and others.
Synthetic fibers: like polyester, polypropylene, polyamide, and so on.
And special fibers: like glass, carbon, bi-component, and others.
A nonwoven fiber can be bonded thermally, mechanically (needle punch), and chemically into nonwoven products.
The company is known for expertise in:
Needle punching is a traditional method of bonding nonwoven fibers into fabric products. It is a process of mechanically interlocking nonwoven fibers webs, using different types of needles. Most nonwoven geotextiles are from needle-punched high-quality nonwoven fibers.
Thermal bonding is also referred to as melt bonding or heat bonding. Nonwoven products that are thermally bonded often comprise synthetic nonwoven fiber (polyester fibers), with some other fibers that operate as the product's binding component. The process of thermal bonding is often carried out by using hot air.
With the use of thermal bonding or mechanic techniques, nonwoven textiles are also laminated with the help of included other components.
Surface can be treated with the use of thermal aplications, smoothening or calandaring.
They use several other techniques of die cutting, such as CNC cutting and Kiss-cutting, which offers you custom designed products.

Sometimes, you can use two or more fibers in nonwoven production. You can blend them to increase the efficiency of nonwoven products like strength, absorbency, and so on. You can also make a blend of natural-natural, natural-synthetic, or synthetic-synthetic.
Nonwoven fabric products made of synthetic nonwoven fibers are widely adopted as a highly efficient medium when producing nonwoven air filters, high-performance oil filters, and other fluid filters.
