This needle is the most commonly used type with a functional cross-section of an isosceles triangle,which can bear warp force from all direction，thus good effect can be achieved in the process of puncture.
This needle with barbs on four edges, can guarantee a high entanglement rate in every puncture but in the meantime minimize the damage on fiber, it is usually used in geotextile .
This kind of needle is produced as single or multi reduced needle ,similar as crown needle, mainly applied to the field of automobile interfacing , carpet and clothing. Compared with crown needle ,fork needle can raise much more velvet on the surface of p
This needle is with formed barbs ,each edge with one barb , and the penetration be 0.1mm .In the process of penetration, almost all the barbs can hook fiber at the same time, and a layer of high quality tufting surface can be produced without needle scar.
A needle with special cross-section of peach shape, which can decrease the puncture resistance and the damage on fiber to a large degree, effectively reduce the rate of broken needles . This kind of needle is usually adopted on paper making blanket and he
This needle is with the first barb opened ,can carry out much fibers but minimize the damage to the fibers ,ensure the best tenacity and excellent insulation.It is mainly used in ceramic fiber insulation felt.
