Frequently Asked Questions | FAQs
What is needle punching non woven fabric ?
Needle punching is a method of producing non-woven fabrics, in which fibers are interlocked and consolidated through the use of needle-like barbed instruments. The process involves laying a layer of fibers on a machine bed and then passing the needles through the fibers to entangle and interlock them, creating a stable web of fibers. This method can be used to produce a variety of non-woven fabrics with different properties, such as strength, softness, and permeability.
Needle punching is widely used in the production of industrial and technical textiles, as well as in the production of consumer products such as filters, geotextiles, insulation materials, and carpet backing. The needle punching process is versatile and can be easily adapted to produce a wide range of fabric structures, from dense and sturdy fabrics to soft and fluffy materials. The resulting fabrics are typically lighter and more flexible than woven fabrics and can be produced more quickly and economically than some other non-woven production methods.
Overall, needle punching is a widely used method for producing non-woven fabrics with a range of properties, and it is well suited for a variety of applications in various industries.
