The advantages of non-woven fabric needle method production

Needle-piercing cloth is produced by the needle-piercing method. The non-proof cloth is completely based on the effect of a mechanical device, that is, the needle puncture effect of the acupuncture machine, which reinforces the bulky fiber mesh structure to obtain super strength. The basic concept is: the use of triangular cross-section (or other cross-section) edges with barbed thorns to carry out continuous puncture on the web. When the barb crosses the web, it forces the surface layer and part of the inner chemical fiber of the web into the interior of the web. Because of the frictional effect between chemical fibers, the originally bulky fiber web is reduced. When the felting needle exits the web, the pierced fiber bundles get rid of the barbs and stay in the web. In that way, many fiber bundles are entangled in the web so that it can no longer repair the original bulk. After countless needle piercing, a lot of fiber bundles are pierced into the fiber web, making the chemical fibers in the fiber web entangled with each other, and then producing a needle-piercing non-woven material with certain super strength and thickness. The needle nonwoven processing methods include pre-needle, main needle, pattern needle, ring type needle and tube type needle and so on.
