Effect Of Density On Quality Of Needle-punched Machine
Dec 12, 2017

The needle density is the theoretical acupuncture number of the fiber net in the unit area (1 square centimeter), and the needle density is the most important process parameter. Generally speaking, the greater the needle density, the stronger the product strength, but, if the fiber network is close enough, then acupuncture will cause fiber damage or broken needles, but will make the product strength decline.

needling depth is the length of the fiber net after the needle puncture, unit for MM, in a certain range, with the increase in the depth of acupuncture, fiber entanglement more fully, product strength has improved, but the thorn too deep, will make fiber fracture, product strength, usually acupuncture depth in the 3~17mm between.
