Non woven felt fabric is one kind of non-woven fabric. It is made of pp, pe, acrylic, and other staple fibers. And made by repeated needling and appropriate heat pressing treatment. According to different processes with different materials, tens of thousands of products can be made. These are used in various industries, and various specifications can be customized according to different applications.

The production of nonwovens by needling is entirely mechanical, i.e. the needles of the needling machine pierce and strengthen the fluffy fiber webs to obtain strength. The basic principle is. A barbed needle with a triangular cross-section (or other cross-section) is used to puncture the web repeatedly. When the barbs pass through the web, they force the fibers on the surface of the web and part of the inner layer into the web. Due to the friction between the fibers, the originally fluffy web is compressed. When the felting needle is withdrawn from the web, the fiber bundles are separated from the barbs and left in the web, so that many fiber bundles are entangled in the web it cannot regain their original fluffy state. After many times of needling, a considerable number of fiber bundles are pierced into the fiber web, so that the fibers in the web are entangled with each other, thus forming a non-woven material with a certain strength and thickness of the needle punching method. Needle punching nonwoven process forms are pre-punching, main punching, pattern punching, ring punching, tube punching, etc.
Non woven felt fabric is used not only for conventional air filtration and dust control but also for cup type masks, water locking and moisturizing of fruit and vegetable vegetation, filling of automobiles, furniture and home textiles, apparel, etc., as well as care products, cushions, thermal insulation series, etc. The use is still under continuous development.
